Relevant tweets from Demis;

 Lee Sedol is playing brilliantly! #AlphaGo thought it was doing well, but got confused on move 87. We are in trouble now... Mistake was on move 79, but #AlphaGo only came to that realisation on around move 87 When I say 'thought' and 'realisation' I just mean the output of #AlphaGo value net. It was around 70% at move 79 and then dived on move 87 Lee Sedol wins game 4!!! Congratulations! He was too good for us today and pressured #AlphaGo into a mistake that it couldnt recover from

If it's true that AlphaGo started making a series of bad moves after its mistake on move 79, this might tie into a classic problem with agents trained using reinforcement learning, which is that after making an initial mistake (whether by accident or due to noise, etc.), the agent gets taken into a state it's not familiar with, so it makes another mistake, digging an even deeper hole for itself - the mistakes then continue to compound. This is one of the biggest challenges with RL agents in the real, physical world, where you have noise and imperfect information to confront.

Of course, a plausible alternate explanation is that AlphaGo felt like it needed to make risky moves to catch up.

In the post-game press conference I think Lee Sedol said something like "Before the matches I was thinking the result would be 5-0 or 4-1 in my favor, but then I lost 3 straight... I would not exchange this win for anything in the world."

Demis Hassabis said of Lee Sedol: "Incredible fighting spirit after 3 defeats"

I can definitely relate to what Lee Sedol might be feeling.Very happy for both sides. The fact that people designed the algorithms to beat top pros and the human strength displayed by Lee Sedol.

Congrats to all!

My friends and I (many of us are enthusiastic Go lovers/players) have been following all of the games closely. AlphaGo's mid game today was really strange. Many experts have praised Lee's move 78 as a "divine-inspired" move. While it was a complex setup, in terms of number of searches I can't see it be any more complex than the games before. Indeed because it was a very much a local fight, the number of possible moves were rather limited. As Lee said in the post-game conference, it was the only move that made any sense at all, as any other move would quickly prove to be fatal after half a dozen or so exchanges.

Of course, what's obvious to a human might not be so at all to a computer. And this is the interesting point that I hope the DeepMind researchers would shed some light on for all of us after they dig out what was going on inside AlphaGo at the time. And we'd also love to learn why did AlphaGo seem to go off the rails after this initial stumble and made a string of indecipherable moves thereafter.

Congrats to Lee and the DeepMind team! It was an exciting and I hope informative match to both sides.

As a final note: I started following the match thinking I am watching a competition of intelligence (loosely defined) between man and machine. What I ended up witnessing was incredible human drama, of Lee bearing incredible pressure, being hit hard repeatedly while the world is watching, sinking to the lowest of the lows, and soaring back up winning one game for the human race.. Just incredible up and down in a course of a week. Many of my friends were crying as the computer resigned.

So AlphaGo is just a bot after all...

Toward the end AlphaGo was making moves that even I (as a double-digit kyu player) could recognize as really bad. However, one of the commentators made the observation that each time it did, the moves forced a highly-predictable move by Lee Sedol in response. From the point of view of a Go player, they were non-sensical because they only removed points from the board and didn't advance AlphaGo's position at all. From the point of view of a programmer, on the other hand, considering that predicting how your opponent will move has got to be one of the most challenging aspects of a Go algorithm, making a move that easily narrows and deepens the search tree makes complete sense.

The crucial play here seems to have been Lee Seedol's "tesuji" at White 78. From what I understand this phrase in Go means something like "clever play" but is something like sneaking up on your opponent with something that they did not see coming. Deepmind CEO confirmed that the machine actually missed the implications of this move as the calculated win percentage did not shift until later.https://twitter.com/demishassabis/status/708928006400581632

Another interesting thing I noticed while catching endgame is that AlphaGo actually used up almost all of its time. In professional Go, once each player uses their original (2 hour?) time block, they have 1 minute left for each move. Lee Sedol had gone into "overtime" in some of the earlier games, and here as well, but previously AlphaGo still had time left from its original 2 hours. In this game, it came down quite close to using overtime before resigning, which is does when the calculated win percentage falls below a certain percentage.

Another way to look at this is just how efficient the human brain is for the same amount of computation.

On one hand, we have racks of servers (1920 CPUs and 280 GPUs) [1] using megawatts (gigawatts?) of power, and on the other hand we have a person eating food and using about 100W of power (when physically at rest), of which about 20W is used by the brain.

AlphaGo's weakness was stated in the press conference inadvertently: it considers only the opponent moves in the future which it deems to be the most profitable for the opponent. This leaves it with glaring blind spots when it has not prepared for lines which are surprising to it. Lee Sedol has now learned to exploit this fact in a mere 4 games, whereas the NN requires millions of games to train on in order to alter its playing style. So Lee only needs to find surprising and strong moves (no small feat but also the strong suit of Lee's playing style generally).

We were discussing the probability that Sedol would win this game. Everyone, including me, bet 90% that no human would ever win again, let alone this specific game: http://predictionbook.com/predictions/177592

I tried to estimate it mathematically. Using a uniform distribution across possible win rates, then updating the probability of different win rates with bayes rule. You can do that with Laplace's law of succession. I got a 20% that Sedol would win this game.

However a uniform prior doesn't seem right. Eliezer Yudkowsky often says that AI is likely to be much better than humans, or much worse than humans. The probability of it falling into the exact same skill level is pretty implausible. And that argument seems right, but I wasn't sure how to model that formally. But it seemed right, and so 90% "felt" right. Clearly I was overconfident.

So for the next game, with we use Laplace's law again, we get 33% chance that Sedol will win. That's not factoring in other information, like Sedol now being familiar with AlphaGo's strategies and improving his own strategies against it. So there is some chance he is now evenly matched with AlphaGo!

I look forward to many future AI-human games. Hopefully humans will be able to learn from them, and perhaps even learn their weaknesses and how to exploit them.

Depending how deterministic they are, you could perhaps even play the same sequence of moves and win again. That would really embarrass the Google team. I hear they froze AlphaGo's weights to prevent it from developing new bugs after testing.

I wouldn't be surprised if, in a month, Lee Sedol was able to beat AlphaGo in another match. This is what happened in chess. The best computers were able to beat the best humans, until the best humans learned how to play anti-computer chess. This bought them a year or so more, until computers finally dominated for good.

According to the commentary of both streams I was watching, after losing an important exchange in the middle (apparently move 79 https://twitter.com/demishassabis/status/708928006400581632) it seems AlphaGo sort of bugged out and started making wrong moves on an already dead group on the right side of the board. After that it kept repeating similar mistakes until it resigned a lot of moves after. But the game was already won for Lee Sedol after that middle exchange. It was really interesting seeing everyone's reactions to AlphaGo's bad moves though.

That was really cool! It seemed after the brilliant play in the middle the most probable moves for winning required Lee Sedol to make impossibly bad mistakes for a professional, which would be a prior that AlphaGo doesn't incorporate. I've heard the training data was mostly amateur games so perhaps the value/policy networks were overfit? Or maybe greedily picking the highest probability, common with tree search approaches, is just suboptimal?

Right now I don't know if I'm more impressed by AlphaGo's artificial intelligence or its artificial stupidity.

Lee Sedol won because he played extremely well. But when AlphaGo was already losing it made some very bad moves. One of them was so bad that it's the kind of mistake you would only expect from someone who's starting to learn how to play Go.

The game seemed to be going in AlphaGo's favour when it was half way through. Black (AG) had secured a large area on the top that seemed nearly impossible to invade.

It was amazing to see how Lee Sedol found the right moves to make the invasion work.

This makes me think that if the time for match was three hours instead of two, maybe a professional player will have enough time to read the board deeply enough to find the right moves.

After AlphaGo won the first three games, I wondered not if the computer had reached and surpassed human mastery, but instead how many orders of magnitude better it was. Given today's result, it may be only one order, or even less. Perhaps the best human players are relatively close to the maximum skill level for go, and that the pros of the future will not be categorically better than Lee Sedol is today.

GoGameGuru just published a commentary of the game with some extra insight https://gogameguru.com/lee-sedol-defeats-alphago-masterful-c...

The author thinks that Lee Sedol was able "to force an all or nothing battle where AlphaGos accurate negotiating skills were largely irrelevant."

[...]

"Once White 78 was on the board, Blacks territory at the top collapsed in value."

[...]

"This was when things got weird. From 87 to 101 AlphaGo made a series of very bad moves."

"Weve talked about AlphaGos bad moves in the discussion of previous games, but this was not the same."

"In previous games, AlphaGo played bad (slack) moves when it was already ahead. Human observers criticized these moves because there seemed to be no reason to play slackly, but AlphaGo had already calculated that these moves would lead to a safe win."

Which, I add, is something that human players also do: simplify the game and get home quickly with a win. We usually don't give up as much as AlphaGo (pride?), still it's not different.

"The bad moves AlphaGo played in game four were not at all like that. They were simply bad, and they ruined AlphaGos chances of recovering."

"Theyre the kind of moves played by someone who forgets that their opponent also gets to respond with a move. Moves that trample over possibilities and damage ones own position achieving less than nothing."

And those moves unfortunately resemble what beginners play when they stubbornly cling to the hope of winning, because they don't realize the game is lost or because they didn't play enough games yet not to expect the opponent to make impossible mistakes. At pro level those mistakes are more than impossible.

Somebody asked an interesting question during the press conference about the effect of those kind of mistakes in the real world. You can hear it at https://youtu.be/yCALyQRN3hw?t=5h56m15s It's a couple of minutes because of the translation overhead.

Lee Sedol definitely did not look like he was in top form there. I would say (as an amateur) his play in Game 2 was far better. It was the funky clamp position that perhaps forced AlphaGo to start falling apart this game. [0]

I wonder if Lee Sedol can find a way to replicate that in Game 5.

Here's the post-game conference livestream:

At the end, Lee asked to play white in the last match, and the Deepmind guys agreed. He feels that AlphaGo is stronger as white, so he views it as more worthwhile to play as black and beat AlphaGo.

Conference over, see you all tomorrow.

Also:

Lee Sedol doesn't have RAM that can be crammed with faithfully recalled gigabytes of information, and that allow exhaustive, yet precise searching of vast information spaces. The amount of short-term information Sedol can remember perfectly is very small by comparison, and doing so requires a lot of concentration and effort.

Secondly, the faculty with which Lee Sedol plays Go wasn't designed for the exclusive task of playing Go. Without having to load a different program, Sedol's brain can do many other things well.

Now that we have two points for interpolation, expectations are down to near best human competency in go using distributed computation. Also from move 79 to 87 the machine wasn't able to detect the weak position, that shows its weakness. Now Lee can try and aggressive strategy creating multiple hot points of attacks to defeat his enemy. The human player is showing the power of intelligence.

This game is a great example for the people that said that AlphaGo didnt play mistakes when it had a better position because it lowered the margin, because it only looks at winning probability.

AlphaGo made a mistake and realized it was behind, and crumbled because all moves are "mistakes"(they all lead to loss) so any of them is as good as any other.

Im very suprrised and glad to see Humans still have something against AlphaGo, but ultimately, these kind of errors might dissapear if AlphaGo trains 6 more months. It made a tactical mistake, not a theory one.

AlphaGo obviously made mistakes in game 4 under the pressure from LSD's brilliant play. I'd like to know if the "dumb moves" are caused by the lack of pro data or some more fundamental flaws with the algorithm/methodology. AlphaGo was trained on millions of amateur games, but if Google/Deepmind builds a website where people (including prop players) can play with AlphaGo, it would be interesting to see who improves faster.

> This was when things got weird. From 87 to 101 AlphaGo made a series of very bad moves.

It seems to me, that these bad moves were a direct result of AlphaGo's min-maxing tree search.

According to @demishassabis' tweet, it had had the "realisation" that it had misestimated the board situation at move 87. After that, it did a series of bad moves, but it seems to me that those moves were done precisely because it couldn't come up with any other better strategy the min-max algorithm used traversing the play tree expects that your opponent responds the best he possibly can, so the moves were optimal in that sense.

But if you are an underdog, it doesn't suffice to play the "best" moves, because the best moves might be conservative. With that playing style, the only way you can do a comeback is to wait for your opponent to "make a mistake", that is, to stray from a series of the best moves you are able to find, and then capitalize that.

I don't think AlphaGo has the concept of betting on the opportunity of the opponent making mistakes. It always just tries to find the "best play in game" with its neural networks and tree search in terms of maximising the probability of winning. If it doesn't find any moves that would raise the probability, it picks one that will lower it as little as possible. That's why it picks uninteresting sente moves without any strategy. It just postpones the inevitable.

If you're expecting the opponent to play the best move you can think of, expecting mistakes is simply not part of the scheme. In this situation, it would be actually profitable to exchange some "best-of-class" moves to moves that aren't that excellent, but that are confusing, hard to read and make the game longer and more convoluted. Note that this totally DOESN'T work if the opponent is better at reading than you, on average. It will make the situation worse. But I think that AlphaGo is better in reading than Lee Sedol, so it would work here. The point is to "stir" the game up, so you can unlock yourself from your suboptimal position, and enable your better-on-average reading skills to work for you.

It seems to me that the way skilful humans are playing has another evaluation function in addition to the "value" of a move how confusing, "disturbing" or "stirring up" a move is, considering the opponent's skill. Basically, that's a thing you'd need to skilfully assess your chances to perform an OVERPLAY. And overplay may be the only way to recover if you are in a losing situation.

Apparently AlphaGo made two rather stupid moves on the sidelines, judging from the commentary. Which incidentally is the kind of edgecase one would expect machine learning against itself is bad at learning, since there is a possibility that AlphaGo just tries to avoid such situations. It will be interesting to see if top players are able to exploit such weaknesses once AlphaGo is better understood by high level Go players.

This was probably the closest game in the series. Livestream: https://www.youtube.com/watch?v=mzpW10DPHeQ

A few months back, the expert consensus was that we were many years away from an AI playing Go at the 9-dan level. Now it seems that we've already surpassed that point. What this underscores, if anything, is the accelerating pace of technological growth, for better or for worse.

In game four, we saw Lee Sedol make a brilliant play, and AlphaGo make a critical mistake (typical of monte carlo-trained algorithms) following it. There's no doubt that with further refinement, we'll soon see AI play Go at a level well beyond human: games one through three already featured extraordinarily strong (and innovative) play on part of AlphaGo.

By the way, for those who want to learn by themselves, there are a lot of ways to play Go against a computer in a way that is friendly for beginners.

My rough journey so far - on a Mac, but much of this can be done on Linux - I started out playing 9x9 games against Gnugo, giving myself as much handicap as possible (without it resigning immediately), and then removing stones as I improve. I got to the point where I could sometimes beat 9x9 when I started with two extra stones, and then I started with 19x19.

Took me a while to win 19x19 with 9 stones, but then I won by learning a bit more about extending on hane. Then you can improve from there.

After that point, you can also switch to fuego or pachi, which are stronger by default. The end result is it really is easy and possible to learn a ton just by playing against software, tracking your ability throughout, just by picking programs with different strength and handicap levels.

I've also enjoyed using GoGui to pit two computer programs against each other and watch how they play with various handicaps.

Then there's all the puzzles - goproblems.com, smartgo, etc. Finally, there are plenty of ebooks you can buy through smartgo books.

This doesn't get into playing against humans on the various servers, but there's plenty of information about that online.

Great game and amazing series/match. This last one was absolutely nail biting. My hat off to the AlphaGo team and to Mr. Lee Sedol. Sedol showed incredible fighting spirit and stamina. Just imagine sitting through a 5 hour game like that last one, with full concentration all the time. And seeing the expression of exhaustion and disappointment on Sedol's face after last moves and his resignation. Phew... I bet that he came in rather confident into this last game, after beating AlphaGo in the fourth, figuring he had found a weakness. And he seemed to have a rather good start, securing a decent territory in the lower right corner. We can all marvel at the machine/software the DeepMind team has built, but still I feel that the real marvel is the human brain. Will we learn anything from this series, about how it functions and evaluates game positions in a stratetgic games? The classic problem/mystery is how extremely good the human brain is at pruning game-trees. Whole branches are thrown out in split seconds and probably never explored. Currently taking a watt-for-watt comparison there is no question about whose "hardware" is superior -> Lee Sedol's brain. But I guess the DeepMind team and the community will take plenty of lessons from this and in a few years span, Lee Sedol's phone will beat him 100% of the time. At least I wouldn't be willing to bet against it, even though we are hitting the roof in Moore's law.

My rough summary of the match, informed by the various commentators and random news stories.

Game 1: Lee Sedol does not know what to expect. He plays testing moves early and gets punished, losing the game decisively.

Game 2: Lee Sedol calms down and plays as if he is playing a strong opponent. He plays strong moves waiting for AlphaGo to make a mistake. AlphaGo responds calmly keeping a lead throughout the game.

Game 3: Lee Sedol plans a strategy to attack white from the start, but fails. He valiantly plays to the end, creating an interesting position after the game was decided deep in AlphaGo's territory.

Game 4: Lee Sedol focuses on territory early on, deciding to replicate his late game invasion from the previous game, but on a larger scale earlier in the game. He wins this game with a brilliant play at move 78.

Game 5: The prevailing opinion ahead of the game was that AlphaGo was weak at attacking groups. Lee Sedol crafted an excellent early game to try to exploit that weakness.

Tweet from Hassabis midgame [0]:

 #AlphaGo made a bad mistake early in the game (it didnt know a known tesuji) but now it is trying hard to claw it back... nail-biting.
After a back and forth late middlegame, Myungwan Kim 9p felt there were many missed chances that caused Lee Sedol to ultimately lose the game by resignation in the late endgame behind a few points.

Ultimately, this match was a momentous occasion for both the AI and the go community. My big curiosity is how much more AlphaGo can improve. Did Lee Sedol find fundamental weaknesses that will continue to crop up regardless of how many CPUs you throw at it? How would AlphaGo fare against opponents with different styles? Perhaps Park Jungwhan, a player with a stronger opening game. Or perhaps Ke Jie, the top ranked player in the world [1], given that they'd have access to the game records of Lee Sedol?

I also wonder if the quick succession of these games on an almost back-to-back game schedule played a role in Lee Sedol's loss.

Myungwan Kim felt that if Lee Sedol were to play AlphaGo once more, the game would be a coinflip since AlphaGo is likely stronger, but would never fix its weakness between games.

After the first 3 games I thought that AlphaGo was far beyond human level, but it's a harder call to make now. It seems very unlikely that an AI would be very close to exactly matching a human, one would expect it to be much stronger or much weaker.

Perhaps humans are closer to the "Perfect Game" than we think? http://hikago.wikia.com/wiki/Hand_of_God The top players estimate they would need a 4 stone advantage to win a perfect player.

While what the AlphaGo team has accomplished is nothing short of amazing, I'm not sure if everyone's thinking about this in the right context. While playing there's a "super computer" behind the scenes with these specs 1,920 CPUs and 280 GPUs [0]. Then consider all the machines used to train this neural net. I'd say Sedol's brain is pretty freaking powerful. Also, with that much computing power I would expect AlphaGo to win with the right team and the right approach to solving the problem. It would be very interesting to change the rules and limit the processing power of the computer playing a human.

Four components:

Learning (viewing millions of professional game moves).

Experience (playing different versions of itself)

Intuition (ability to accurately estimate the value of a board)

Imagination (evaluating a series of "what if?" scenarios using Monte Carlo Tree Search)

I think the significant thing about AlphaGo is that apart from some hand-crafting in the Monte Carlo Tree Search routines, this is all general purpose programming.

It may only be baby-steps, but it does feel like a genuine step towards true (general) AI.

Really interesting and close match, it was great listening to the expert player analyse the game and having the final score be uncertain until very late in the game.

I found the discussion around weaknesses in the Monte Carlo tree search algorithm interesting. It sounds like the opinion from the expert is that there are some inherent weaknesses in how MCTS tends to play moves against theoretical moves from the opponent that don't make sense; ie. that AlphaGo sees a potential win that would only happen if the human player made very bad moves. It's fascinating that the seeming weakness in AlphaGo would come from the algorithmic part of the AI and not the neural net. Could it be that as the neural net becomes stronger and stronger at the game, eventually the algorithmic part of it would become less useful to it? If that's the case, it really feels like this could be the path to truly general AI.

I tried to learn Go a decade ago. After spending some time on it, I came to the conclusion that it's just not an enjoyable game for me. Here's why:

As you can see in this match, games are often won and lost by just a few points (1% of the whole territory). So, not only do you have to count territory precisely at the end, but throughout the game, and this isn't easy to do in your head.

Maybe if you are an autistic accountant, that's fun, but not for me. If I have to play a strategic board game, it will be good old chess. And now that computers are finally beating people at both, there is no longer any need to look at Go as some kind of mythical last refuge of humanity.

Google improved the outcome by putting in large amounts of processing power. What happens, if humans would do the same?

Instead of just Lee Sedol, how about putting the top 10 Go players in a room vs. AlphaGo? Would the chance to win increase?

Maybe we find out, that 3 top go players vs. AI is the optimal way and adding more humans decreases the odds to win the match?

This would lead to following question: Why does AI improve, if we add more processing power while adding more human brainpower decreases their overall power?

Maybe we find out, that 3 good developers working on a project are optimal and more decrease the chance of success?

What's needed to use programs like AlphaGo to enhance human enjoyment of Go (and other games like chess where i have more experience)? I'm more interested in this than in the "man vs. machine" narrative.

Ideally we could take AlphaGo and produce an algo that can smoothly vary its playing proficiency as a human opponent increases in skill. The problem I've seen in chess computers is that setting them to "amateur" results in 3-4 grandmaster-perfect moves followed by a colossal blunder to enable the human opponent to catch up.

Ideally you could use a computer opponent as an always-available, continuously adapting challenger to train hard against all the time.

Would it be conceivable that similar type of AI can deploy and manage unmanned military vehicles, e.g. unmanned drones and tanks, and monitor battle progress (assuming that the other side is managed by human)? It wouldn't necessarily be turn-based, but constantly evaluating its moves against changing environment outside its control and reach its objective? I think such future is conceivable and scary at the same time.

I question how much of it's success is down to the AI/understanding the game/outplaying the opponent vs. simple culled brute force. Especially when they can throw Google level computing power at it and they have mentioned using heat maps and looking at move sets.

It could be argued that it's only AI when it understand the game rules and plays to them without iterating random choices until it finds a hit. Machine learning would be between the two, but still not what many would consider true AI.

What I'm finding terrifying is that we compare best players of entire human population to machine. Even if machine is only barely on the same level, honestly, 99.9% of people probably wouldn't stood a chance against it, no matter how hard they would be trying. Those professional players are best of best.

Now compare that level of AI with average person. Go game might not be directly applicable to our lives, but it's only a demonstration. And it's replicable as easy as copy'n'paste, compare that to amount of time, money and efforts required to grow and train a human.

That future where not only drivers and factory workers are replaced by robots, but anyone who's not doing extremely intellectual work, is getting closer. Factory robot is not that cheap, it requires manipulators, repairs. But cheap office work does not require anything physical, it's replicable extremely fast and gonna cost very low. It's exciting and terrifying feature. It's not going to look well with current capitalistic economical model.

I almost overlooked this article because I got turned off by the opening description in base 10, as there is a lot of math trivia out there that is specific to base 10 which holds little general significance.

But a little further down, the article discusses how this was discovered originally in base 3, and I think it's much simpler to understand in that context, since all primes except 3 (aka 10 base 3) end in just either 1 or 2:

"Looking at prime numbers written in base 3 in which roughly half the primes end in 1 and half end in 2 he found that among primes smaller than 1,000, a prime ending in 1 is more than twice as likely to be followed by a prime ending in 2 than by another prime ending in 1."

The results are particularly striking in base 11 - looking at primes below 100 million, only 4.3% of primes ending in 2 are followed by another prime ending in 2 (compared to the 9.1% you would naively expect) with similar numbers for other pairs.

A prime ending in 2 (in base 11) is also unlikely to be following by a prime ending in 5, 7 or 9, whereas it is particularly likely to be following by a prime ending in 4 or 8.

It would be interesting to know what structure there is (if any) in this NxN "transition matrix" for various bases.

Here is my attempt to work through the math and figure out how "surprising" this result is.

Clearly, we should expect that for small primes (< 100e6) it is less likely that a prime ending in K (in base B) will be followed by another prime ending in K - because for that to happen, none of the B-1 numbers in between can be prime.

A (very naive) model of the distribution of primes says that every number n has probability p(n) = 1/log(n) of being prime. Assume that a number n ends with a k in base b. Define p = 1/log(n). Then the probability that the next prime ends in k+j is, roughly,

 q(j) = p * (1-p)^(j-1) * sum_{i=0}^{infinity} (1-p)^(i*b) = p * (1-p)^(j-1) / (1 - (1-p)^b)
In this formula, j takes values 1 to b (where j = b represents another prime ending in k).

For n ~ 1,000,000 and working in base b, under this model we would expect to see around 6.97% of primes ending in k followed by another prime ending in k, whereas we expect to see 13.7% of primes ending in k+1 (it is apparent how naive the model is, since in fact we never see a prime ending in k followed by a prime ending in k+1, except for 2,3). It would not be hard to extend the model to rule out even primes, or multiples of 3 and 5, but I have not done this.

Around n ~ 10^60 the distribution starts to look more equal, as the primes are "spread out" enough that you expect to have long sequences of non-primes between the primes, which blurs out the distribution to be roughly constant.

I think this is what the article is getting at when it quotes James Maynard as saying "Its the rate at which they even out which is surprising to me". With a naive model of 'randomness' in the primes, you expect to see this phenomenon at low numbers (less then 10^60) and for it to slowly disappear at higher numbers. And indeed, you do see that, but the rate at which the phenomenon disappears is much slower than the random model predicts.

I think that is why it is surprising.

I don't think this is true at all. Take a look at the famous Ulam Spiral: http://scienceblogs.com/goodmath/wp-content/blogs.dir/476/fi...

You can see that while prime numbers are difficult to predict, they're anything but random. I'm not sure why the article is claiming that mathematicians used to think the distribution of primes was evenly distributed, which is complete and utter nonsense.

For those willing to try this over toy code, I did a (horrible, horrible, I'm terribly ashamed of it) quick Python snippet to check it out:

 def primer(): p = 3 while True: is_prime = True for x in xrange(2, p): if p % x == 0: is_prime = False break if is_prime: yield p p += 2 give_prime = primer() primes = [1, 2] # had to separate this into 2 lines because Python primes.extend([give_prime.next() for x in xrange(9998)]) # so we get 10,000 primes primes_dict = {} for i in xrange(len(primes) - 1): p0 = str(primes[i])[-1] p1 = str(primes[i + 1])[-1] key = "".join([p0, "-", p1]) try: primes_dict[key] += 1 except: primes_dict[key] = 1 # let's delete the 4 outliers from the begining del(primes_dict["1-2"]) del(primes_dict["2-3"]) del(primes_dict["3-5"]) del(primes_dict["5-7"]) 
So long story short, my results over 10,000 primes:

 In [57]: primes_dict Out[57]: {'1-1': 365, '1-3': 833, '1-7': 889, '1-9': 397, '3-1': 529, '3-3': 324, '3-7': 754, '3-9': 906, '7-1': 655, '7-3': 722, '7-7': 323, '7-9': 808, '9-1': 935, '9-3': 635, '9-7': 541, '9-9': 379}
And you can clearly see that the tendency to avoid the same last digit is starting to show, thow those that end in 1 are still not showing it completely. Tried with 100,000 primes but the (horrible) algorithm kinda got stuck so I settled with 10,000 to make this a "quick test".

Before you go, please believe me I'm sorry for primer() and give_prime. I'll try to never do those kind of things again.

Edit: I've edited this like 5 times already over little typos and bad transcription mistakes I did all over the place. Should work now.

Primes seem to me to be more of an information theoretic concept than a number concept.

Primes are the simplest way to encode specific kinds of graphs that unambiguously encodes all sub-graphs.

If you try to come up with a bit-representation that is equivalently rich it becomes difficult to think of one that is as simple yet preserves the semantics of the factorization tree.

So I guess my point is that the factorization tree of numbers is the fundamental concept, and it's information theoretic. Primes happen to be an encoding of that fundamental concept into integers, but if we found an equivalently rich representation using a different encoding, we might understand primes better. I doubt that the quirks of the encoding has anything to do with the fundamental concept however.

I once was really interested in finding patterns in prime numbers. I got a long csv file of prime numbers from the internet. I used symbolic regression on it, to try to predict the next prime in the list.

Symbolic regression basically uses genetic algorithms to fit mathematical expressions to data. The program I was using, Eureqa, tries to find the simplest expressions that fit, with only a handful of elements. To prevent overfitting, and give a human understandable model.

Anyway this actually worked. Far from perfectly of course, but it was able to get much better than random predictions. It was definitely finding some pattern.

Unfortunately I used up Eureqas free trial forever ago, and I'm not going to pay thousands of dollars to buy a subscription. But I am now thinking of writing my own software to do this, and then running it on a dataset of mathematical sequences like the primes.

Unless I'm doing something wrong, it honestly it doesn't seem like the actual prime numbers have a statistic that deviates from random numbers with a prime distribution. Hence it looks like to me just the result of a) specifying the "next" number which naturally favors the digit after it and b) probability of a given number being prime (prime number theorem).

For those who have Mathematica and want to experiment with this, here's a quick function to generate the data:

 f[n_, base_] := Module[ {m, d, dpairs}, d = Table[Last[IntegerDigits[Prime[i], base]], {i, 1, n}]; dpairs = Table[{d[[i]], d[[i + 1]]}, {i, 1, Length[d] - 1}]; Map[#[[1]] -> #[[2]] &, Tally[dpairs]] ]
For the first n primes in a given base, it returns the mapping {i,j}->count for the all pairings of digit i followed by digit j. E.g., for the first million base 5 primes

 {2, 3} -> 68596 {3, 0} -> 1, {0, 2} -> 1, {2, 1} -> 64230 {1, 3} -> 77475 {3, 2} -> 72827 {2, 4} -> 77586 {4, 3} -> 64371 {3, 4} -> 79358 {4, 1} -> 84596 {1, 2} -> 79453 {4, 2} -> 58130 {4, 4} -> 42843 {1, 1} -> 42853 {3, 3} -> 39668 {2, 2} -> 39603 {1, 4} -> 50153 {3, 1} -> 58255

It should be noted that from the original paper, the asymptotic formula that Oliver and Soundararajan conjecture still says that each possibility for the last digits of consecutive primes should occur about the same number of times in the limit. It's just that the amount by which the frequencies vary is more than you would expect from the most naive model of primes as being "random".

As a non-mathematician, this is a pretty neat read. I was distracted by the personification of the numbers though (they have 'likes' and 'preferences', which in my day-to-day vocab are concepts applicable only to things that possess the ability to think). Is this common in mathematical writing, or is this paper an abnormality in that sense?

(I don't mean to nitpick - I'm genuinely curious. I recall seeing the same thing in high-school chemistry, but never in physics, for example, and I'm curious if entire fields see this effect or if it's a product only of the audience being written to).

I just spent 5 minutes looking for a chart showing the distribution of reserved commands in Python. Didn't find much.

A while back, I read something about different number bases' ability to help find additional primes. The base itself was prime, so maybe 7 or 13. Can't find the article ATM. I hypothesized that prime numbers are "code" provided by this universe to allow us to access other data stored in other primes. Quines of a sort, if you will. One way to invalidate this hypothesis would be to do a mean distribution of basic operators in a simple programing language and compare it to what we are seeing in primes.

Just based on this knowledge, I know that a prime number is guaranteed not to be immediately followed by another one with the same ending 1 time in 2.

Counter-intuitive at first but makes sense - the outcomes as a whole converge towards the average (50% heads, 50% tails). Nonetheless, it shows that each toss is related to the others. One can expect that primes are even more related - or at least to the primes that came before.

Does a prediction based on base 3 hold up better over primes under 100 than 1000 and 1000 than 10000?

Is the ratio of how well a base ending sequence is predictive scale to a predictable range based on the base that the prime number field is viewed within?

Just thinking about what might be happening, I would imagine that the answer is yes, but that a lot of crunching would be needed to graph and deduce a relationship to an actual predictive property statement.

> Quanta MagazineNUMBER THEORYMathematicians Discover Prime ConspiracyA previously unnoticed property of prime numbers seems to violate a longstanding assumption about how they behave.

Zim + Teemo for Quanta MagazineBy: Erica KlarreichMarch 13, 2016Comments (2)

Share this:facebooktwitterredditmailPDFPrintTwo mathematicians have uncovered a simple, previously unnoticed property of prime numbers those numbers that are divisible only by 1 and themselves. Prime numbers, it seems, have decided preferences about the final digits of the primes that immediately follow them.

Among the first billion prime numbers, for instance, a prime ending in 9 is almost 65 percent more likely to be followed by a prime ending in 1 than another prime ending in 9. In a paper posted online today, Kannan Soundararajan and Robert Lemke Oliver of Stanford University present both numerical and theoretical evidence that prime numbers repel other would-be primes that end in the same digit, and have varied predilections for being followed by primes ending in the other possible final digits.

Weve been studying primes for a long time, and no one spotted this before, said Andrew Granville, a number theorist at the University of Montreal and University College London. Its crazy.

The discovery is the exact opposite of what most mathematicians would have predicted, said Ken Ono, a number theorist at Emory University in Atlanta. When he first heard the news, he said, I was floored. I thought, For sure, your programs not working.

This conspiracy among prime numbers seems, at first glance, to violate a longstanding assumption in number theory: that prime numbers behave much like random numbers. Most mathematicians would have assumed, Granville and Ono agreed, that a prime should have an equal chance of being followed by a prime ending in 1, 3, 7 or 9 (the four possible endings for all prime numbers except 2 and 5).

I cant believe anyone in the world would have guessed this, Granville said. Even after having seen Lemke Oliver and Soundararajans analysis of their phenomenon, he said, it still seems like a strange thing.

Yet the pairs work doesnt upend the notion that primes behave randomly so much as point to how subtle their particular mix of randomness and order is. Can we redefine what random means in this context so that once again, [this phenomenon] looks like it might be random? Soundararajan said. Thats what we think weve done.

Prime Preferences

Soundararajan was drawn to study consecutive primes after hearing a lecture at Stanford by the mathematician Tadashi Tokieda, of the University of Cambridge, in which he mentioned a counterintuitive property of coin-tossing: If Alice tosses a coin until she sees a head followed by a tail, and Bob tosses a coin until he sees two heads in a row, then on average, Alice will require four tosses while Bob will require six tosses (try this at home!), even though head-tail and head-head have an equal chance of appearing after two coin tosses.

Can someone explain this?

Perhaps I have missed something, but the introductory example seems to follow from simple probability and therefore I do not find it mathematically remarkable.

Say, there is a fixed and equal probability that each number ending with 9 and 1 is prime. I could go along with that assumption, although the fact that primes get less likely as you go higher is potentially relevant.

What the authors consider here is starting with a prime ending in 9.So the next potential prime ends in 1. If only because 1 is the next number to be checked, a 1-prime is more likely to appear next than a 9-prime. The probability of that can be calculated, depending on your assumptions, as a geometric sequence. In any case, P(next prime is 1) > P(next prime is 9).

"Most mathematicians would have assumed, Granville and Ono agreed, that a [known] prime should have an equal chance of being followed by a prime ending in 1, 3, 7 or 9" So - I'm a definite nope on that.

This result appears to be exactly what I would have assumed was the case.

Not to be a downer, but was any thought given to the safety of the plastic(s) used?

This is something that's in your mouth a lot and constantly exposed to saliva.

The Dimension 1200es mentioned doesn't appear to be specific to medical applications.[0] The product page lists the only compatible thermoplastic being ABSplus-P430. The MSDS for that basically says the stuff is dangerous in molten form, and beyond that there's very little data.[1] The same company makes "Dental and Bio-Compatible" materials for use with their other products, and these appear to have considerably more safety data.[2]

>The aligner steps have been printed, in addition to a riser that I added in order to make sure the vacuum forming plastic (sourced from ebay) ...

As another commenter pointed out, the vacuum forming plastic is probably the primary concern because the 3D printer was just used to create the molds. The specific type of vacuum plastic isn't mentioned.

Regardless, very neat project.

It looks like the author took into account the safety of the plastic in creating these, which is a good thing. Maybe more so than dentists. You know "silver" fillings aka dental amalgum? They are 50% mercury by weight and are still being used. Supposedly safe because it is inhalation of mercury that is poisonous. Removal of those fillings with a drill can be dangerous. When some guy told me about this and was talking about it being the next asbestos/mesothelioma, I was thinking "sure! That sounds like conspiracy crap!" Then I looked it up on the FDA site like he suggested:

There is not really much tech required. You can simply cut apart the gypsum model tooth by tooth and align it perfectly with wax and add space for you gum. Finally create a mold and use medical grade silicone to make the tooth straightener.

Silicone also allows for more movement and gives you control of upper and lower teeth in relation to each other.

While this is not rocket science there are considerations about jaw alignment that would be difficult for the amature to get right the first time around in any but simple misalignments.

I'm not trying to downplay how much the hacker/geek in me loves this, however, as a former* dental student, I would highly suggest not trying to pull this off on your own.

First, teeth and their movement is more complicated than it might first seem. You have to think about the entire masticatory apparatus, for example:

There's more root than crown, how does the root move in relation to the tooth? Root resorption is a common problem in orthodontic treatment.

Is there / will there be enough bone surrounding the tooth to support the intended movement?

How will the patient's occlusion (how the teeth fit together) be affected? Part of the Invisalign process is to take a bite registration that shows the upper and lower teeth in relation to each other. This is important, and ignoring it can potentially lead to other complications:

- stress fractures

- supraeruption of opposite tooth

- TMJ pain

Does the patient display any parafunctional habits that will affect the new tooth positions? For example, do they grind, clench, or have abnormal chewing patterns?

Many Invisalign techniques require the placement of anchors, holds, and various other structures attached to the teeth themselves. They allow for more complex movement than the insert itself would be able to provide.

Adjustments are often required mid-treatment. Not everybodys anatomy and biology is exactly the same, so you have to adjust accordingly.

Now, does every general dentist take this into account 100% of the time? No, but theyre at least trained to recognize these situations and compensate for them.

That said, many simple patients dont require any more thought than the OP put in. Its a good thing he looked in a text book and realized that theres a limit to how much you should try to move a tooth at each step before youre likely to run into problems. And if you do run into problems do you think a professional is going to come anywhere near your case?

A few issues I have with his technique:

Unless he poured his stone model immediately after taking the impression, its likely there was a decent loss in accuracy. Alginate is very dimensionally precise, but only for about 30 minutes. The material that most dentists use, PVS, is dimensionally stable for much, much longer (not to mention digital impressions).

Vertical resolution of the 3D print does matter. You might be moving teeth in only two dimensions, youre applying it over three dimensions.

Again, I think it is awesome that someone gave this a shot, and did a fairly good job as well. Im all for driving the cost of these types of treatments down, as well as promoting a more hacky/open approach to various treatments. Just know theres more than meets the eye.

* I decided to go back to tech, theres too little collaboration in dentistry for me to make a career out of it.

> No, David. If I were in the job now, I would have simply told the FBI to call Fort Meade, the headquarters of the National Security Agency, and NSA would have solved this problem for them. They're not as interested in solving the problem as they are in getting a legal precedent.

That's quite the quote, especially given his history of employment.

The weirdest thing about this whole cell-phone saga to me is that the perps are dead, did not appear to be part of some organized group and that very little could be done to them that hasn't been done already based on evidence found on the phone.

Then there is the bit that a lot of the information that is on the phone is also already in the log files of the carriers. It's as if that phone somehow magically is going to yield an entirely new class of information that may not even exist in the first place.

To me it has been evident from day one that this is not about this phone or the data that's on it but just about the legal precedent, getting it in black-and-white from the former head of counter terrorism is quite an indictment of his successors.

The larger issue, by far, is whether we are a free people.

From the article:

 CLARKE: No, the point I'm trying to make is there are limits. And what this is is a case where the federal government, using a 1789 law, is trying to compel speech. And courts have ruled in the past, appropriately, that the government cannot compel speech. What the FBI and the Justice Department are trying to do is to make code writers at Apple - to make them write code that they do not want to write that will make their systems less secure.
If the FBI gets its way in this case, forcing Apple employees to perform a service for the government, then it sets the precedent for the government to compel anyone to do anything the government wants. When you are forced to work for someone against your will, this is called slavery.

Of course the FBI used a terrorist attack to try and get what it's always wanted, and it will abuse the unlock power in the future if it gets it now, but judges could easily cite this case as a defense for the government to compel other action from the people.

Clarke makes it sound like there is court precedent against this compulsion, but that would be overturned if the FBI wins.

Indeed, encryption and privacy are very important, but our very liberty is more important.

I think Apple and all other tech companies that support it move as the FBI (or whoever controls the FBI) expected or wanted.

What was revealed a few years ago was the fact that big tech companies betrayed people's trust. So quite naturally they should attempt to regain that trust. Because if majority of people stop trusting tech companies and start using end-to-end encryption, use of encryption stops working as a signifier that indicates a higher likelihood that the user's doing something wrong. Thus it's crucial to keep ordinary people away from using encryption. In order to achieve this, it's important to make people trust big tech companies again.

In my opinion, this is what the writer of the plot of the dispute between the FBI and Apple thinks.

I am surprised that a search for "math" only turned up one result in this thread, about car accidents vs terrorist victims.

Isn't it true that encryption legislation or policy is sort of irrelevant next to the very clear math that says encryption will always be ahead of decryption? Even in a (hopefully avoidable) dystopia where encryption is illegal, would that really stop technology companies from continuing to do what they've always done?

John Oliver has a great segment[1] where he notes that the majority of cheap, available encryption applications aren't even US-based, and so it becomes nigh-impossible for our (or any) government to stop any pedestrian from encrypting.

Encryption and privacy are what make this reality work. You think you are you. I think I am me. This reality's ability to keep those separate is a privacy feature. From a Buddhist's perspective our understanding (Dharma) is that we are, on some level, all the same entity.

One of the early sutras put it this way:

> "Discrimination is consciousness. Nondiscrimination is wisdom. Clinging to consciousness will bring disgrace but clinging to wisdom will bring purity. Disgrace leads to birth and death but purity leads to Nirvana."

Encryption gives the means by which we can enable privacy between ourselves, or what we think of as self. If we enable complete privacy from all others, we drop into a self-world. If we disable privacy, and join all the others disabling privacy, we drop into an isolated type of Nirvana, with the implication everything becomes quite boring. I have compared this in the past to the observed push and pull of public and private cloud business models.

One solution may come via virtual realities where we can arrive at consensus in a fair and measured way without centralized control. It is my belief that immutable data structures backed by encryption, such as a blockchain, are the path out of this mess.

Just thinking it _should_ be much harder to compel individuals to do something like this than it is to compel a corporation.

The Apple situation annoys me because it's no longer about the web. It's about breaking crypto on a device which is vendor-locked. The same thing as breaking homegrown crypto, or DVD crypto; easy and trivial. The fact that Apple doesn't use ephemeral keys and can't simply throw away the key in the event of an incident is worrisome enough.

Real crypto needs to be more compartmented than that. A bank is not secure because of the massive door - it's safe because it would take a thief weeks to empty every safety deposit box.

It's also made even safer when the key is (more or less) thrown away for periods of time and nobody can get it. Even with manual over-ride. Literally somebody could be dying inside the safe and nobody could save them.

In properly implemented crypto nobody should hear you scream.

I want to point out one other thing about this project, if only to assuage my guilt. And this community of hackers and entrepreneurs seems as good a place as any to clear the air.

There is a necessary abridgement that happens in media like this, wherein a few individuals in lead roles act as a vignette for the entire effort. In particular, on the software team, James and I are highlighted here, and it would be easy to assume we did this whole thing ourselves. Especially given very generous phrasing at times like "Turner rebuilt Magic Pocket in an entirely different programming language".

The full picture is James and I were very fortunate to work with a team of more than a dozen amazing engineers on this project, that lead designs and implementations of key parts of it, and that stayed just as late at the office as we did during crunch time. In particular, the contributions of the SREs didn't make it into the article. And managing more than half a million disks without an incredible SRE team is basically impossible.

> Measuring only one-and-half-feet by three-and-half-feet by six inches, each Diskotech box holds as much as a petabyte of data

This number is very interesting. Basically Diskotech stores 1PB in 18" 6" 42" = 4,536 cubic inch volume, which is 10% bigger than standard 7U (17" 12.2" 19.8" = 4,107 cubic inch).

124 days ago Dropbox Storage Engineer jamwt posted here (https://news.ycombinator.com/item?id=10541052) stating that Dropbox is "packing up to an order of magnitude more storage into 4U" compared to Backblaze Storage Pod 5.0, which is 180TB in 4U (assuming it's the deeper 4U at 19" 7" 26.4" = 3,511 cubic inch). Many doubted what jamwt claimed is physically possible, but doing the math reveals that Dropbox is basically packing 793TB in 4U if we naively scale linearly (of coz it's not that simple in practice). Not exactly an order of magnitude more but still.

Put it another way, Diskotech is about 30% bigger in volume than Storage Pod 5.0 but with 470% more storage capacity.

That was indeed some amazing engineering.

It's an interesting subject. I'll never click on or be persuaded by ads, so they're not really gaining anything by showing me ads. I'm essentially worthless traffic to them no matter how they cut it.

I do understand the problem they're trying to solve, and I would like to pay for content that I find worthwhile. A convenient microtransaction protocol where I _don't have to sign in or interact in any way_ would be nice.

So, just for fun. The video quotes "over 1PB" of storage per box.

I count 6 columns of 15 rows/drives. Might be 7 columns even, there's some panels that aren't fully open on the video.

So, 90-105 drives. I'm guessing they are using 10TB drives, although maybe they can get bigger unannounced drives? Roughly, the math seems to check out.

Quite impressive. Guess the Backblaze guys need a Storage Pod 6.0 soon :P (I know, I know, different requirements/constraints)

From a business sense, this is a great move. Amazon's cloud storage offerings are pretty expensive, even with various deduping strategies in place, Dropbox needed both store and move in and out massive amounts of traffic. If DB had reached the point where they could staff the extra over head of doing it themselves, and figure out how to spread the hardware cost out well, it will give them more pricing flexibility in the near future.

Key points:

1. Dropbox moved from AWS to its own datacenters after 8 months of rigourous testing. They didn't exactly build a S3 clone, but something tailored to their needs, they named it Magic Pocket.

2. Dropbox still uses AWS for its European customers.

3. Dropbox hired a bunch of engineers from Facebook to build its own hardware heavily customised for data-storage and IOPS (naturally) viz. Diskotech. Some 8 Diskotech servers can store everything that humanity has ever written down.

4. Dropbox rewrote Magic Pocket in Golang, and then rewrote it again in Rust, to fit on their custom built machines.

5. No word on perf improvements, cost savings, stability, total number of servers, amount of data stored, or how the data was moved. (Edit: Dropbox has a blog post up: https://blogs.dropbox.com/tech/2016/03/magic-pocket-infrastr... )

6. Reminds people of Zynga... They did the same, and when the business plummeted, they went back to AWS.

7. Not a political move (in response to AWS' WorkDocs or CloudDrive), but purely an engineering one: Google and then Facebook succeeded by building their own data centers.

Oh dear I didn't realise Dropbox had invested all of that time and money moving into their own data centre. From my perspective the future of Dropbox looks bleak. Mass storage with Amazon is much cheaper [edit: from a consumer perspective]. I know Dropbox has superior software that works (as opposed to the poor apps by Amazon and Google) but I imagine a lot of people are like me i.e. Store most of the stuff at the cheapest location and use Dropbox just for docs that you want to sync on multiple devices. Total income from consumers like me equals 0.

Dropbox also had that email app didn't they that they recently announced was closing down - mailbox if I recall correctly.

Can anyone convince me that this move by Dropbox isn't going to end very badly for them?

Should All Research Papers Be Free? nytimes.com

If it is funded by government in any way (public university, research project) I think it is borderline defrauding the tax payer that the research funded by tax-money is not free by default. Since close to all research is government funded in some way, shape or form...my answer would be yes in the general case.

I think the long term answer is decentralized publishing. Publish everything you do on a university or private website and let others decide if it's good or not when they want to cite it instead of a peer review that is set in stone. I think people reading papers deciding if they want to cite you are smart enough to figure out if it's good research or not. The peer review process is overrated (and quite often suffers from insider networks). If you decentralize publishing you can also have other researchers upvote a paper to basically approve of the academic standards in the paper.I also think the static nature of papers is a problem. I'd much rather cite a specific version of the paper. I'm thinking about git and pull requests along the lines of "want to cite, fixed layout" or "new research disproves this" etc.

Full disclosure: I'm a founder of a company called Scholastica that provides software that helps journals peer-review and publish open-access content online. One of our journal clients, Discrete Analysis, is linked to in the NYT article.

It is incredibly obvious that journal content shouldn't cost as much as it does.

- Scholars write the content for free

- Scholars do the peer-review for free

- All the legacy publishers do is take the content and paywall PDF files

Can you believe it? Paywalling. PDFs. For billions.

Of course the publishers say they create immense value by typesetting said PDFs, but as technologists, we can clearly see that this is bunk.

There's a comment in this thread that mentions the manual work involved in taking Word files and getting them into PDFs, XML, etc. While that is an issue, which you could consider a technology problem, it definitely doesn't justify the incredible cost of journal content that has been created and peer-reviewed at no cost. Keep in mind that journal prices have risen much faster than the consumer price index since the 80s (1).

The future is very clear, academics do the work as they've always done and share the content with the public at a very low cost via the internet.

PS. If you want a peek into how the publishers see the whole Sci-Hub kerfuffle, check out this post from one of their industry blogs - the comment section is a doozy: http://scholarlykitchen.sspnet.org/2016/03/02/sci-hub-and-th...

When I finished my PhD at Northwestern, part of the university's procedure involved going to the ProQuest Web site. ProQuest is a journal and dissertation publishing company.

They asked if I wanted my dissertation to be available, free of charge, to anyone interested in reading it.

Clicking on "yes, I want to make it available for free" would cost me something like $800.

Clicking on "no, I'll let you charge people to see it" would cost me nothing.

Having just finished, and being in debt to do so, it shouldn't come as a surprise that I wasn't rushing to pay even more. So now, if people want to see my dissertation, they have to pay -- or be part of an institution that pays an annual fee to ProQuest. (BTW, e-mail me if you want a copy.)

My guess is that it's similar with other journals. And while professors have more than PhD students, they have limited enough research funds that they'll hold their nose, save the money, and keep things behind a paywall.

Which is totally outrageous. It's about time that this change, and I'm happy to see what looks like the beginning of the end on this front.

Taxpayer funded research must be free to read.

Also, a research that has been at least partially tax-funded resulting in a publication, must not be usable as an necessary ingredient for a commercial patent.

That is, a patent can include this type of research, but it cannot be a 'necessity' for the patent to be viable. Or, if the particular research, is necessary for a given patent to be viable, the patent must grant no-fees, no-commercial-strings-attached use.

This allows a corporation to establish patents as means to protect itself, while allowing the tax funded research to be used by others without commercial strings attached

Yes. They should.

It is in the best interests of humanity to make the knowledge obtained through research available to anyone looking for that knowledge. There is a clear consensus among scientists that the current publishing model is at best inexpedient and at worst hostile to that end.

Most people are asking what good the current publishing model provides, but I think to answer that question we need to ask: "compared to what?" It seems clear to me that the current model is better than having no publishing mechanism at all, but I doubt that anyone seriously thinks that the "none" model is the only alternative.

I think that if we sat down today and thought up a new publishing model from scratch, we would be able to outdo the status quo on just about every "good" people have mentioned here, as well as provide features that the current model is incapable of. I think it is highly likely that we could make a system that ran on donated resources alone.

Some things we might want/have in a "from scratch" model:

1. Direct access to data-as-in-a-database instead of data-as-a-graph-in-a-PDF

2. Blockchain-based reputation system for scientists

3. P2P storage and sharing of scientific data

4. Tiers of scientific information, e.g. an informal forum-of-science, semi-formal wiki-of-science, and formal publications

5. Automated peer review process

6. A better and more consistent authoring tool for scientists

Something I'd like to see here: results published in research papers aggregated and released as open data.

There must be a lot of interesting meta-analyses that aren't getting done because the necessary data is locked away behind paywalls, and usually not in an easily machine readable format into the bargain.

University presidents love to tout how important their scientists are because they publish in these journals.

For me, this is the cog of the problem. People who are in a position to change should push for it.

The main problems with tax-funded research and grants is that money is given in return for citations in journals with high "impact factor". As a result, publishers of those journals are indirectly supported by the state. Instead, government or funding organizations should review the results of the work for themselves, but they are unable to do it, because they usually don't understand a thing about research subject.

Publishing used to cost money when it required physical printing/distrubution/storage of journals. Now all of this is basically free, but they still charge. Most theoretical physicists for example only care about "publishing" in the ArXiv (all free, open source). The traditional publishing is ridiculous.

This isn't the right question. The question is, "Who should be profiting from research papers?" The Journal performs quality control for the sake of consistency and prestige, but the papers and their reviews are put together by researchers, commonly at great cost for marginal personal gain. The article's hero doesn't really care. She needs to read papers, and needs other people to be able to read them, so she built sci-hub (demo: https://sci-hub.io/10.1038/nature16990).

I was thinking a good startup company may be an open publication and peer review site. Something where users are non-anonymous and they are weighted by their accomplishments irl. Submissions and peer reviews would be open to anyone but weighted heavily by ranking, which is affected by irl achievements and cumulative quality contributions to the site. Like a combination of stack overflow and wikipedia maybe.

Money would be made by donation (ala wikipedia) and paper submission fees. Perhaps organizational level membership fees, such as universities, etc.

Just an idea I haven't had time to work on.

What follows is just my very uninformed opinion. I'm not a scientist myself, but my interest in CS and math has made me an avid reader of scientific papers and books - whenever they're publicly available, that is.

What publishing houses do is exploit the rules of the social games that scientists themselves willingly play. When the importance of an academic work is judged by the names of its authors, or by the name of the journal in which it is published, or by the presence of fashionable keywords in its title or in the abstract, scientists are giving publishing houses the very rope with which they will be hanged. So, while the behavior of publishing houses is certainly antisocial and most abominable, it is only made possible by the very scientific community that condemns it.

Is there any fundamental reason why scientists can't always submit their papers to the arXiv, and let the web of citations determine their relative importance?

I am still willing to pay for a high-quality printed version of research journals, but for the online access I think we should simply give away because research knowledge should belong in the public domain when you choose to publish the knowledge with a research journal. You are not publishing a paper within your 4x4 walled intrnaet.

But I get it. There is a business cost behind running a journal / magazine (although not all reputable one charge fees!). So here is the radical question: why the fuck do we need 100+ CS-related journal publishers out there? All we need is one.

It takes time, effort and money to publish and peer review research. If journals can't make money providing access to the research who is going to pay for it?

Also there is currently a lot of BAD research out there. Domain experts don't have time to review all of it. Journals with prestigious names act as filters and as sort of priority queues for where you should look first.

Because no vote exists without enlighten choices.

Chosing without relevant information on future choice that will impact every one require citizens that can have a constructed opinion. And experts are doing a poor job at being right. (look at the financial regulations made by experts and the long lasting crisis since 2000).

> But that financial model requires authors to pay a processing charge that can run anywhere from $1,500 to $3,000 per article so the publisher can recoup its costs.

These two facts seem to point strongly to the publishers' being in the right. 30% is not a high number. If they were to lower their prices by 30%, running completely as nonprofits (or whatever number would break even), do you think people's complaints about difficulty of access would go away? If not, your complaining is not about their profit.

And you can't seriously expect them to eat a >$1000 loss on every paper.

Either we need a single party to fund upfront, like the government, or we need some other way to pay for it.

The narrator voice style is also pretty much the same that is used in those. I wanted to like these videos but I did not feel that they had any value what so ever.

Once again, I am so glad that I caught this on the live-stream because it will be in the history books. The implications of these games are absolutely tremendous. Consider GO: it is a game of sophisticated intuition. We have arguably created something that beats the human brain in its own arena, although the brain and AlphaGO do not use the same underlying mechanisms. And this is the supervised model. Once unsupervised learning begins to blossom we will witness something that is as significant as the emergence of life itself.

Perhaps the last big question was whether AlphaGo could play ko positions. AlphaGo played quite well in that ko fight and furthermore, even played away from the ko fight allowing Lee Sedol to play twice in the area.

I definitely did not expect that.

Major credit to Lee Sedol for toughing that out and playing as long as he did. It was dramatic to watch as he played a bunch of his moves with only 1 or 2 seconds left on the clock.

My (long) commentary here:

https://www.facebook.com/yudkowsky/posts/10154018209759228

Sample:

At this point it seems likely that Sedol is actually far outclassed by a superhuman player. The suspicion is that since AlphaGo plays purely for probability of long-term victory rather than playing for points, the fight against Sedol generates boards that can falsely appear to a human to be balanced even as Sedol's probability of victory diminishes. The 8p and 9p pros who analyzed games 1 and 2 and thought the flow of a seemingly Sedol-favoring game 'eventually' shifted to AlphaGo later, may simply have failed to read the board's true state. The reality may be a slow, steady diminishment of Sedol's win probability as the game goes on and Sedol makes subtly imperfect moves that humans think result in even-looking boards...

The case of AlphaGo is a helpful concrete illustration of these concepts [from AI alignment theory]...

Edge instantiation. Extremely optimized strategies often look to us like 'weird' edges of the possibility space, and may throw away what we think of as 'typical' features of a solution. In many different kinds of optimization problem, the maximizing solution will lie at a vertex of the possibility space (a corner, an edge-case). In the case of AlphaGo, an extremely optimized strategy seems to have thrown away the 'typical' production of a visible point lead that characterizes human play...

It is interesting how fast this has happened compared to chess.

In 1978 chess IM David Levy won a 6 match series 4.5-1.5 - he was better than the machine, but the machine gave him a good game (the game he lost was when he tried to take it on in a tactical game, where the machine proved stronger). It took until 1996/7 for computers to match and surpass the human world champion.

I'd say the difference was that for chess, the algorithm was known (minimax + alpha-beta search) and it was computing power that was lacking - we had to wait for Moore's law to do its work. For go, the algorithm (MCTS + good neural nets + reinforcement learning) was lacking, but the computing power was already available.

We are indeed witnessing and living a historic moment. It is difficult not to feel awestruck. Likewise, it is difficult not to feel awestruck at how a wet 1.5 kg clump of carbon-based material (e.g. Lee Sedol brain) can achieve this level of mastery of a board game, that it takes such an insane amount of computing power to beat it. So, finally we do have a measure of the computing power required to play Go at the professional level. And it is immense, or to apply a very crude approximation based on Moore's law, it requires about 4096 times more computing power to play Go at the professional level than it does to play chess. Ok, this approx may be a bit crude :)

But maybe this is all just human prejudice... i.e. what this really goes to show is that in the final analysis all board games we humans have inveted and played are "trival", i.e. they are all just like tic-tac-toe just with a varying degree of complexity.

Finally, I also feel that while experience is crucial, the older generation would flush out by the younger generation every decade. I wonder if age really play a role in championship - not that AlphaGo isn't considered a 1000 years old "human" given it has played thousands of games already.

This looks like the "Sensing" feature that Honda has implemented on some of their other vehicles. I just bought a 2016 Accord that does the same thing -- there's a camera mounted on the windshield, another camera in the front grille, and a radar sensor on the front bumper.

Calling it "self-driving" is kind of a misnomer and I think the article kind of blows it out of proportion.

It will track the car in front of you and keep a safe following distance, keeping either the maximum cruise control speed you've set, or whatever speed the vehicle ahead of you is driving, whichever is slower. It will accelerate or brake accordingly. It will also attempt to stay in the lane by using the onboard cameras for tracking the lane markings.

The lane keeping assist is not nearly as autonomous as the article makes it out to be. It does not like to work on sharper curves on the freeway, for one -- the system will disengage and tell you to steer manually. It still wants you to keep your hands on the wheel. It must be looking for very very subtle movements on the wheel, because the system will yell at you if you take your hands off the wheel for longer than 10-15 seconds.

All in all it's a pretty cool feature for longer road trips (keeping in your lane can just get kind of tiring, even with cruise control) but it's not the sort of autonomous driving that the article here paints it out to be.

Americans could rather use a robot highway driving instructor.

"Consider moving over to the right line; you're driving at the speed limit, and a speeding car is approaching; you may confirm this in the rear-view mirror."

"I have detected that you came to a full stop at the end of a generous freeway entrance ramp in light traffic. Suggested future action: look over the shoulder as early as possible and match the speed of the traffic."

"Suddenly exiting out of the left lane is dangerous. Please know which exit you're supposed to take, watch for its approach early, and change lanes ahead of time. If you miss an exit, do not make a sudden, dangerous action. Look for an alternate route or U-turn starting at the next exit."

Just for comparison, you can get a Subaru Legacy Premium with Eyesight for $25,835 (or a Crosstrek for thereabouts, and an Outback for $2-3K more), since at least summer 2015. So nothing Honda are doing here is revolutionary technologically, they're just bringing the same technology to a new market ($5K cheaper), which is still something.

I highly recommend that if you invest in THIS technology that you go all in and get the blind spot detection and rear cross traffic alerts. I have had a Subaru with Eyesight for over six months now, and I don't regret buying it and definitely like the blind spot/cross traffic alerts, they're legitimately useful day to day.

I will say one downside of this system is what I call "alert fatigue" particularly lane drift warnings, ice warnings, traffic pulled away warnings, etc. You can disable many of these, but it would be my only whine.

I have had automatic braking pre-warn me a handful of times, but not had it activate yet except when I pulled into the garage and the dangling tennis ball confused it and even then it only slowed me slightly. You get a yellow warning then red, then brake, and most of the warnings are legitimate I am just ahead of them.

Lane keep assist and distance based cruise control are like crack. It feels like you just get on the freeway, push a few buttons, and the car almost drives itself.

The article really wants to compare with electric vehicles, for some reason. The subheading says "they are being snapped up faster than electrified vehicles." This is repeated in the article, which says the relevant options packages "are being snapped up at a far higher rate than electrified vehicles." Discussing the Q50's technology package and how many buyers opt for it, it says "Thats three times as many people who pay extra to buy a hybrid-electric version."

What's the deal? Is this just because Tesla happens to be the one with the best system at the moment? It doesn't make any sense to me, and really distracts from the article's main thrust.

The real problem with self-driving cars is the car to human handoff. Over the long term it's incredible unlikely that humans will be any good atall at remaining aware and 'up to speed' on the current situation in the event that the car needs to give control back to the driver due to road conditions, hardware failure, or sudden situation that it cannot contend with.

Conversations about self-driving have focused on zero defect rate in-city self-driving vehicles, but a lot of these technologies are reaching Pareto-efficient levels of usefulness. I don't need my car to drive the first and last miles; I'd be perfectly happy if it just drove on the highway.

And why do humans drive long haul trucks for anything other than the first and last miles? Trucks should drive themselves between depots at the edges of metros and then humans can drive them into the city. https://www.mercedes-benz.com/en/mercedes-benz/innovation/th... "Self steering"... How long before that moniker is replaced by "Self driving".

And why are humans delivering packages? They might not be for long: http://www.reuters.com/article/us-starship-delivery-robot-id...

It's going to shock our economy once industries begin constraining roles to the level at which robots can be "good enough". After figuring out how to manage them, we'll start to see robots deployed in force.

The elephant in the room is this one:

When will highways be upgraded/updated for self driving? I don't mean V2I (vehicle to infrastructure) capabilities, but properly painted and maintained lane lines, reflectors, and signage. The infrastructure is just not there. You can't simply rely on a car's sensing abilities for self driving.

Am I missing something? Why is this top news? There are several cars out there with adaptive cruise control. In fact, I think most mainstream cars offer it as an option now. It's pretty impressive but calling it "self-driving" is hyperbole.

Subaru's eyesight is technically even more impressive considering it does image processing to detect vehicles, whereas most of these systems are based on radar. Although I don't see the point because radar is more reliable IMO. Unless you use some features which only camera can provide (stop at traffic lights?), which Subaru doesn't yet do. From whatever research I did before buying a car, Volvo's system (uses both radar and camera) seems to be one of the best overall, along with Mercedes, and Subaru being a close third.

This is a interesting proposition for Honda, but really not that new. Even the price is not /that/ new.

In fact, this is technology that has been sold at around the same price point in the industrial transportation sector -- think of logistics and lorries -- for quite a while. This is where the majority of the innovation is taking place.

For example, just this week it has been revealed that the UK Govt will likely to announcing tomorrow funding for driverless truck convoys in the North of England. What's the price differential between these intelligent trucks and regular trucks? $0.

In fact, so much innovation is taking place in the industrial sector that just last week Toyota announced that it has hired the FULL workforce of Jaybridge Robotics, a firm that specializes in autonomous industrial vehicles, mainly in the agricultural sector.

If you want to understand the tailwinds in the sector, follow the b2b and industrial segment of the market. Technologies and trends are already starting to filter down.

I'm curious about whether this is going to be a net win or lose for safety.

If users treat these automated cruise systems as a "magic self-driving device" when it can potentially make mistakes or hand back control when it's confused, drivers are going to die.

If people "really want to look at their cell phones", and they take this as the tool that lets them pay no attention to the road, it better be up to that task.

The title is a bit misleading. I have a 2016 Civic Touring that has the Sensing Package. It's effectively a sensor package (cameras in the top-middle of the windshield and below passenger-side headlight) with integration with the steering and powertrain systems and very basic logic.

When you turn it on the car basically tries to stay in your lane by looking at the lines on the road. It actually tells you when it can and cannot see the lines. When it detects you going outside of the lane (without using your signal) it takes control of steering and corrects for you. You can also set it to stay within some distance of the car in front of you and it will control your speed. Supposedly, it will also auto-brake if you are in danger of collision but I haven't had a chance to test that yet (and hope not to have to).

The whole thing is more like a driver assistance system and if you take your hands off the wheel for more than 15 seconds or so a bunch of alerts start going off and the system disengages. After using it for a few months I think this is probably a good idea. There are quite a few places in the SF Bay area that have worn out and faded lines on the road and once the system loses sight of the lane markers it just stops working. Not a great moment to have your hands off the wheel or your eyes closed. ;-)

For the price its incredible that Honda offers something like this. Suburu offers something similar but the next best thing is buying a Tesla for much more. I treat it sort of as insurance on long trips. If I start dozing off or am distracted the system keeps me in check but it is not reliable enough to be truly autonomous. So yeah, it can sort of drive autonomously.

As a preview of the future it gives me hope and it's possible this may be the last car I actually buy (when cars drive themselves it could very well become a service industry).

I've owned three cars with automatic cruise control for the past decade. This isn't exactly new technology, perhaps only at this price point.

The first car I had with this, an '06 Infiniti, was only able to slow to a crawl, not a full stop. So while it was useful on the highway it was useless in stop and start.

The second car, a '11 BMW, added "Stop & Go" to the formula. Great? Not quite. What would happen is that the car would come to a full stop, and then a timer would run, and if the car didn't start moving again within 10 seconds the cruise control would shut off, and to resume you'd have to push the pedal. This was especially maddening when stop & start traffic is inconsistent and the stops last 10.5 seconds. Basically the idea of being able to set & forget was completely undermined by this and driving with the feature on was more stressful than driving with it off and just doing everything manually. A complete bust. I don't know why it does this but I can see it being some combination of the product team needing to ship the feature in the state it was in, and legal requirements.

The problem with both of these implementations is that they promised to alleviate some of the issues with past "auto-drive" features (and you should consider Cruise Control to be the very first auto drive feature), but introduce their own. If you want the user experience of set & forget, you need very predictable conditions if you want any of these mass market systems to work for you, and unfortunately that's just not the way the roads are.

I think I have the feature in my latest car too, but I've given up and decided to enjoy manually driving, and just wait for fully autonomous vehicles.

How do we as drivers keep up with the rising levels of automation? It's challenging but doable for owners, but imagine jumping from a pain old 1990s car into a flashy new rental with all the bells and whistles... With a bit of exaggeration, one might make a case for individual type rating, like airliner pilots need to have.

Before we reach fully autonomous driving, we might see an age of widespread "car illiteracy", with more and more people who have a driver's license, but who have completely lost touch with the state of the art in car UI concepts. With not enough time on automatic transmission, people here in Europe occasionally even struggle with something as simple as park/neutral/reverse/drive (don't ask my where I got that)

Sounds like these cars are far from self driving. Just some added safety features that resemble self driving but, are dangerous to use without a foot near the break and hands on the wheel.

I think this sentence pretty much says it all, "For instance, some owners have posted videos of hands- and foot-free driving on YouTube and the car inevitably makes a mistake.".

It sounds like these features are going to end up being abused and probably causing serious fatalities. As we have seen people want to txt and even watch movies while driving. These new features will allow wreck less drivers to pay less attention to driving and more attention to how many Instagram followers they have.

I'll be sure to pay more attention to people driving Honda civics when I'm on the highway.

This looks like the same functionality the Tesla Model S has. One of the big draws for the new Model S cars. So much so that people are getting rid of their older Teslas because they did not have the autopilot.

I thought it's only a matter of time before autopilot becomes common place but it looks like its happening sooner than I thought. The good thing is this has nothing to do with the car being electric or not. But the main thing is, if Tesla thought its going to be a differentiator in terms of calling their cars "luxury" its going to be a problem for them. Given that the internals of the Model S itself are not particularly luxorious they need to think about it.

From the article: "as long as lane markings remain visible and another vehicle is in front of the car." That's more like platooning, which was demoed two decades ago in Demo 97 [1], than self-driving. Are there more details about how this works, especially about autopilot disconnect and user takeover? Tesla's system is known to have trouble with offramps.[2] (Tesla customers are very forgiving. "It's a beta", one says in their forum.)

Honda's follow-the-leader system avoids some of Tesla's problems. Radar systems for not rear-ending the car ahead are already pretty good, and many are already on the road. Lane following by lane markings isn't that reliable, but restricting it to following the car ahead handles traffic jams nicely while locking out most of the hard cases.

The deployment of self-driving systems which are much dumber than Google's is worrisome. I've written before of the "deadly valley" of automated driving. This is another "deadly valley" system. The deadly valley begins where the driver can take their hands off the wheel and tune out. It ends where the automated system can correctly handle more situations than a human driver.

Google is trying hard to get to the far side of the deadly valley. That's good. Look at the problems they're having. Their only known fender-bender in autonomous mode was when the vehicle was trying to deal with a drain blocked with sandbags and very slowly maneuvered around it, to be hit by a bus, while in a wide lane at a right turn, because the AI misjudged the likely behavior of the bus driver. Google's dealing with the hard edge cases. Cruise, on the other hand, ran into a parked car in San Francisco when the autopilot lost lane tracking, veered left, overcorrected right, and the driver took back control too late. That's a more basic failure.

It also shows the problem with semi-autonomous systems. Expecting the driver to compensate for failures of the automation will not work.

Volvo Car Group President and CEO Hkan Samuelsson says that the company will accept full liability whenever one of its cars is in autonomous mode.[3] He has it right. This needs to be a requirement before the "move fast and break things" crowd gets on the road.

It would be nice if GitHub supported a Gerrit-inspired code-review process, where instead of having to choose between:

1) piling new commits onto the existing branch/PR, or

2) force-pushing and completely losing the old commits on the server

You could instead push into a "magic" ref-spec and the server would retain the original commits, but also the rewritten commits, such that a PR can have multiple revisions. This is somewhat hard to explain unless you're familiar with Gerrit and its "patch set" workflow.

Why? Because my preference is to rewrite history in order to address code review comments, such that what is finally merged leaves a clean history. But it is also valuable during the code review process to be able to look across the revisions to make sure everything has been properly addressed.

The only way to do both, today, is to create a new branch and PR for each "revision". i.e. new-feature, new-feature-rev1, new-feature-rev2. Then close the original PR and reference it from the new PR. A bit tedious.

One of these changes, and one that annoys me every single day, is when I get an email about a comment, the email doesn't include any context (e.g. it should include the previous comments on that line and probably the hunk as well). And when I click "View on GitHub" to see it in context, if the commit is now on an outdated diff, I get taken to a page that doesn't show the comment at all. It takes me to the Files view, but the Files view doesn't show outdated comments. If the comment is on an outdated diff then it really should take me to the Conversation view with the comment in question expanded.

Only related to review in a somewhat indirect way, but I really wish the commit view on github (as well as other git tools) had an equivalent of --left-only command line option to git-log. It's incredibly useful for viewing a high level of the history of a repo that uses merge bubbles, and lack of tooling around doing just that seems like that main reason people do things like squash their branches before merging to master (which is where I think it connects back to review).

I can't say I'm a fan. If I select a single commit, instead of giving me a list with a single commit check-marked, it gives me only that single commit and an option to 'show all commits'. So to change the commit you are viewing requires clicking 'show all commits' (waiting for them to load) and then selecting the other commit you want to view (which should just be a check box).

Also it totally baffles me that these actions all require server-side requests. It's really a lot easier to go to the old commits tab, and to ctrl click an open tab for each commit then to use this new feature.

At one point Github offered the best and cleanest UI of all the alternatives - but I doubt this will be the case for long at this rate.

I've noticed some open source projects (particularly Angular 2) follow this convention where they never actually "merge" the PR, but rather rebase it into their main branch and have a message in the commit to close the PR.

The advantages seem to be that you get a cleaner git history, and you can keep all the "in-between" / WIP commits that tell the story. Is this done through an automated tooling or is someone manually rebasing it into master? It seems to be a really useful practice so I'm curious how people do it. It would be great if GitHub could offer this natively, as I think many power Git users appreciate the benefits of rebasing over merging.

What's really great about this is that it's a joke on the future that's been predicted so many times already, my favorite of which being the last vignette on Disney's Carousel of Progress. The future family is talking about points in a video game, and the oven hears it and turns the temperature way up, ruining another family Christmas dinner - the joke being that this convenience was finally going to make Dad able to not ruin dinner.

Somewhat related story: me and some coworkers were talking in a room where someone had a Windows 10 laptop being used to present some data. We were talking as usual when the laptop suddenly decides to open a browser to a Bing search with what looked like a few (badly) voice-recognised words of our conversation. That was a rather awkward moment, given that we were discussing some extremely confidential information, and not helped by the "did someone say 'Hey Cortana'?" the laptop's owner promptly blurted out. If I remember correctly, none of us said anything that sounded remotely like that phrase, yet it activated.

It's now company policy that built-in microphones have to be disabled, and only external ones are allowed to be used when necessary.

I think they need to pick a different name. 'Alexa' is very easy to trigger with other names, and reliably activates when I am watching any show with a character named 'Alex', 'Alexy', etc.

One side effect I've noticed is that they seem to have tried to account for it, which has made the Echo less responsive to actual requests; a few times I've stood in front of it yelling 'ALEXA' trying to get it to stop and it does not respond.

This happens to me with Siri and podcasts - I listen to podcasts in my car, through my iPhone. Occasionally what people say will sound close enough to "Hey, Siri" that it stops the podcasts and and answers whatever question it could extract from the talking following what it thought was "Hey, Siri".

It's repeatable, too. One time it happened right as I was parking, on an episode of This American Life. (Or Serial. Or Planet Money. Yeah, yeah, I listen to a lot of NPR shows.) So I kept rewinding back over that part, and it kept triggering Siri.

I have experienced a similar thing while freelancing or design and web development. I used to work 16 hours some days and less hours others, but then sometimes I would need to work and found it hard to kick it into gear.

I think creativity is like a well, and when you do creative work its like drawing that water out. If you use too much water one day, the well runs dry. You have to wait for the goundwater to fill it up again.

Not only did I begin viewing creativity as a limited resource I create and have access to over time, but I noticed that some activities, like reading about science, listening to music, and walking around town actually increase the rate at which the well fills up.

So now I have made it a daily habit of doing things that inspire me, and I also daily draw from the well like the author said - but Im more careful not to creatively 'overdo it' and leave myself unable to be creative the next day.

Viewing it this way has helped a lot, for all the same benefits the author listed. Im in a rhythm where I dont feel I need a break on the weekend, I just still have energy.

If I told you that every car needed 8 gallons of gas to drive 100 miles, you'd point out I was wrong - so many different makes and models, not to mention variables from tire pressure to driving style.

Yet for the potentially even more complex range that is different people, it amazes me that so much of the advice is didactic - we all need 8 hours sleep, 8 glasses of water, and 8 hours of work with breaks is optimal.

The closest I get to advice is 'learn your body and what works for you'. Thanks to the OP for sharing what works for him.

I started contract work last fall. I set me rate assuming a 25 hour work week. At first I tried working ~4 hrs / day everyday day. I quickly realized this did not work for me. Working everyday, even just a little is not sustainable for me. I have a family and they are still on the 9 to 5 schedule, so working even a few hours on weekends cut into my family time which is important to me. So now I force myself to take at least one weekend day off with no prgramming. This is hard because I love to program. Also I have a hard cutoff time during the week days at about 5:30pm when my wife and kid get home. I usually feel like I want to keep working but that forces me to stop (at least until my daughter goes to bed). So now I work 5 or 6 days a week but seldom exceed 6 hours/ day. Most days are closer to 4hrs. It's great at this pace because I usually always feel like i want to keep programming so I don't get burnt out. And if I do have an off day I just don't work.

The problem I am running into now is what do I do with my spare time? All my hobbies are computer based (video games and Raspberry Pi projects) but I am trying to minimize my screen time in my off hours. This will get better in the spring and summer as the weather gets better but during winter on the Oregon Coast going outside is hit or miss.

And I hear you about not being able to go to bed until I solve a problem I am stuck on, that drives me crazy.

As a freelancer, I understand where some of the comments "As a freelancer this won't work" are coming from. However, the last year I've flipped my freelancing model where I offer a more productized service with a clearly defined scope and set price. Instead of doing design work for $XXX/h, I'll deliver A,B,C within Timeframe Y, for Price $XXXX. With clearly defined services, I've actually been working for the last 12 months using a similar model, usually constraining myself to 4h/day with weekends off. My productivity + revenue have increased dramatically. Productizing your service makes it easier to market and generate leads, while it gives you the flexibility to work the way you want and actually free up time. Awesome post OP!

I agree with this article mostly, although 3 hours a day might be too little to make good progress with work for some people.

This article reminded me of my previous workplace (about 7 years ago) where my manager discouraged engineers from working for more than 6 hours a day. He recommended 4 hours of work per day and requested us not to exceed more than 6 hours of work per day. He believed working for less number of hours a day would lead to higher code quality, less mistakes and more robust software.

Although, he never went around the floor ensuring that engineers do not exceed 6 hours of work a day, and some engineers did exceed 6 hours a day, however, in my opinion, his team was the most motivated team on the floor.

3 hours a day is just not enough for everyone.

For some projects it's perfectly fine but some tasks can only be done if you focus for a large amount of time on it, work obsessively on it until you reach a milestone.

The greatest work I have ever done, was always done when I retreated like a monk for several weeks, cutting myself of the whole world and working almost non-stop on the task until I made a significant breakthrough.

Then I go back to the livings and share the fruits of my work, and of course, take a well deserved rest for several days.

The trap into most people fall is that they are confusing being active and working.

I agree with the author with some exceptions: when you are working as a contractor or freelancer for someone else's project maybe 3h/day is not acceptable. When you've got externally imposed deadlines 3h/day may not be sufficient.

But i agree that working less than 8h/day could be really more productive. I also liked the "less stuck for coding" topic as "...it is sometimes hard to go bed without solving some unknown issues, and you dont want to stop coding in the middle of it..." so maybe forcing themselves to stop could be a solution.

Anyway, i would really like to work 4 or 5 hours a day but keeping holidays and weekends free from work and i think this can only be achieved if you can pay your living with products of your own such as your apps and not by freelancing (i am a freelance and i know it!).

But i enjoyed the idea behind the article and i will try to achieve it one day.

I'm pretty sure this has worked for the author, and it will work for a lot of other people as well, but a lot the benefits raised can still be achieved when working more than 3 hours a day.

A few points are raised in the post:1. If you only work 3 hours, you're less tempted to go on twitter/facebook/hacker news.

True - but that's really a question of discipline, work environment and how excited you are about what you're working on.It's perfectly possible to perform for 10 hours straight without distractions, just make sure to take an occasional break for physical health.

2. Better prioritization.

Treating your time as a scarce resource helps focus on the core features. But your time is a scarce resource even if you work 12 hours a day.Programmers are in shortage. They cost a lot. And the time you're spending on building your own apps could have been spent freelancing and working for someone else's apps.Always stick a dollar figure on your working hours. Even if you're working on your own projects.You should always prioritize your tasks, and always consider paying for something that might save you development time (Better computer. better IDE. SaaS solutions, etc).

3. Taking a long break can help you solve a problem you're stuck on.

Personally, I find that taking a short walk, rubber duck debugging or just changing to a different task for a while does the same.If I'm stuck on something, I don't need to stop working on it until tomorrow. I just need an hour or two away from it.

I mostly agree with the author, but I don't see the point of stopping yourself when you're "in the zone". Why lose the flexibility?

What works for me is having a baseline of 3 or 4 hours of daily work, and not imposing any hard limits when I want or need to do extra hours. This works out great, because I have no excuses not to do the boring routine work as it's just a few hours, but I also have the liberty of doing obsessive 10h sessions when I'm trying to solve a tough problem or when I'm working on something fun.

When I was freelancing there were a lot of days when I didn't do much but then there were days when I got into the flow and worked 2 or 3 days almost straight. Most of the time this ended up at around 40 hours/ week on average but in spurts. This was probably the best work environment I have ever been in.

I hate about the corporate workplace that it doesn't accept any kind of rhythm but treats you like a machine that performs exactly the same at all times. Nature is built around seasons and so are humans. They are not machines.

Historically, working 24 hours a day (I include sleep because after a certain number of hours you even dream of code or your business) for 1 year typically accomplishes more than working 3 hours per day for 8 years. Or 1.5 hours per day for 16 years. There is just some kind of economy of scale.

---------

EDIT: I got downvoted. Come up with whatever standard of productivity you want (ANY standard that you want) and adduce a single human who in 16 years times 90 minutes per day accomplished more than I can find a counter-example of someone doing in the same field in 1 year. 1 year of 24 hours a day strictly dominates 16 years of 90 minutes per day, and you cannot find a single counterexample in any field from any era of humanity. Go ahead and try.

oh and by the way, in 1905 Einstein published 1 paper on the Photoelectric effect, for which he won his only nobel prize, 1 paper on Brownian motion which convinced the only leading anti-atomic theorist of the existence of atoms, 1 paper on a little subject that "reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics by introducing major changes to mechanics close to the speed of light. This later became known as Einstein's special theory of relativity" and 1 paper on Massenergy equivalence, which might have remained obscure if he hadn't worked it into a catchy little ditty referring to an "mc". You might have heard of it? E = mc^2? Well a hundred and ten years later all the physicistis are still laying their beats on top.

https://en.wikipedia.org/wiki/Annus_Mirabilis_papers

Your turn. Point to someone who did as much in 16 years by working just 90 minutes per day.

Closer to our own field, Instagram was sold for $1 billion about a year after its founding date, to Facebook. Point out anyone who built $1 billion in value over 16 years working just 90 minutes per day.

When I first found out about the web, early 90's, and it was "obvious" that the role of the web was to expand scientific publishing. I expected that everybody would publish latex files (raw source, not PDFs) in computationally accessible formats, with raw data in easily parseable, semantic forms.

That didn't really happen as expected. In my own chosen field (biology) it happened much more slowly than I hoped- physics (with arxiv) was far better. However, just getting PDFs on biorxiv is only a small part of the long game. I did not appreciate the huge importance placed on publishing in high-profile journals has on one's career trajectory and how large a role that would play in slowing the transition to free publication and post-publication review.

The long game is to enable the vast existing resources, and the new resources, to be parsed semantically by artificial intelligence algorithms. We've already passed the point where individuals can understand the full literature in their chosen field and so eventually we will need AI just to make progress.

While this is nice in that it sets the example (and provides publicity to bioarxiv) it's not a couple of Nobel laureates that post one out of dozen(s) of papers/year published that will make the real difference.

The system is aged and inefficient (some would even argue it's rotten) and IMO comprehensive changes are needed. Like racial or gender discrimination can't be addressed without changing the social rules people live by, the current academic system that's rather elitist, non-inclusive, discriminatory, often more biased and less fair than many think needs to change substantially.

Such change will be aided by important people setting examples (and often going back to their old ways). However more substantial change is needed on multiple levels, most importantly: academic leaders and funding agencies (run by the former) need to stop looking at who's who and how many Nature/Science/insert-your-fancy-journal papers does the person have. For instance, the culture of applying for grant money with work that's half done to maximize one's chances needs to stop and so should the over-emphasis of impressive and positive results.

Additionally, publishers exploiting everyone need to die out and as long as these researchers "go rogue" with a single paper (rather than for instance committing to publish 100% preprints and >75% open access), not much will change.

But seriously, given the increasing "media savviness" of subsequent generations (from Baby Boomers who grew up with TV, to Gen Y for whom the Internet is a given), the general ability across the spectrum of humanity to synthesize disparate information sources and filter them, compare and contrast, decide what is 'truthy' vs actually true... is increasing. Given all the information scientists have to process... What if machine learning was applied to this problem? The role of traditional gatekeepers is breaking down. I see this is the publishing industry - lots of content, most of the self-published books are awful, but books like "Wool" are able to rise to the top.

At least I hope humanity is getting more sophisticated. What is the median of the age of Trump supporters and the one sigma std dev? That would be an interesting statistic.

The pictures are not bad, but the captions are incredibly cringe and condescending. Of course he would not bother to tell us how to disable the delete in the firmware. Seriously, I mean, thousands of people have gone on these state-sponsored package tours in North Korea and we see the same set of trains, roads, hotels and attractions that they have really got boring.

One photography project I do found interesting is the set below commissioned by Getty Images. The photographers they hired found a loophole in their visa conditions, managed enter NK from Russia and reached Pyongyang on trains rarely used by tourists. They were able to interact more with the locals since the border guards as well as people en route have not been "coached" to speak to foreginers and the whole thing came out feeling much more genuine than these tourist flicks.

I went to North Korea in January as an American (incidentally on the same tour as the kid who is currently being detained there and in the same group). As mentioned in the article, Americans can't go on the train, so I can't speak to his experiences specifically, but I have a few reactions to this.

1. He probably didn't need to modify his camera firmware - I took pictures of basically whatever I wanted and they didn't look or care. The only exception to this was the (singular) grocery store, which I thought was hilarious because it was actually pretty nice. (With surprisingly good food, too! I'm still snacking on some of the candies I bought there.) I went on a helicopter ride and took a bunch of pictures of anti-aircraft guns and the like hoping that they would make me delete them and I would have a story to tell, but no such luck.

2. There's a big difference between the different tour companies. Some of them really sold the dystopian totalitarian state experience, with extremely strict guides who yelled at people on the tour and checked everybody's cameras and so on. The people on those tours seemed to have signed up for that experience and were, I think, happy to receive it. My group was drunk off our collective asses literally 24/7, our guides were making dick jokes, a guy wandered off on his own on New Years Eve and didn't get back to the hotel until ~3am after getting in a fistfight with a cab driver, and it was generally a party. It seems to me like the author of this article went in looking for a dystopia to photograph, and the tour company gave him one.

3. North Korea is poor as hell, obviously has a horrible government, etc. If you've been to other extremely poor parts of the globe it's obvious that it's a poor country trying to pretend to be a rich one. The successful example of neighboring South Korea makes their failure to provide for their citizens even sadder. But I would guess total quality of life is comparable or better in the DPRK than many other places I've been. (Somalia, nasty bits of Bangladesh, etc)

4. The citizens and possibly government are (not totally unreasonably) terrified that the US is going to invade and crush them like ants at any given moment. I think this drives a lot of their government's malinvestments.

NK is really a surreal place, no matter how much you learn about it, something new will still shock you

for example, I watched a documentary about a Western eye doctor who went there pro bono to do cataract surgeries

the thing was, when he gave people their sight back they didn't thank him, they went up to a picture of 'Dear Leader' and wept and prostrated themselves in a cathartic show of gratitude

Pictures are okay if not just generic NK photos, definitely not rare, and the captions, wtf?

"At night, the elderly Chinese dance in the streets in unison avoiding any displays of individuality."What is this? To avoid any display of individuality??? I just marvel at this wishful thinking. They do that in unison because it's fun to do activities with other people sharing the same interest. If i'm playing Starcraft with a bunch of friends, am I avoiding display of individuality? Why can't the biased eyes just state the obvious that the elderly are just enjoying themselves.

Honestly I've seen way better NK photos and way better wishful NK journalism. Why is this even on Hacker News?

Most interesting comments by the photographer:

>"Anyone who composes a work that has not been assigned to the writer through this chain of command is by definition guilty of treason. All written works in North Korea must be initiated in response to a specific request from the Workers Party."

>"After the Korean War, North Korea was economically a more attractive destination than South Korea, and many people, including 100,000 ethnic Koreans from Japan, were welcomed into North Korea."

>"in North Korea you only travel big distances by bus or train, when you get permission."

>"This was one of the most strange moments - when we finally arrived in Pyongyang. Through the courtains of the compartment window, we looked at a surreal scene that appeared like something out of a theatre in its perfection and artifice. Elegant men, beautiful women, walking in a simulated hurry, travellers without a reason (ours was the only train that day), all to impress us and so that the station doesn't look empty."

WOW. What an ignorance.

1) NK's ICBMs program is much more advanced than SK's2) Young generation is openly doubting the regime3) There's a lot of smuggling of SK's soap operas and music4) Their nuclear research is top-notch considering the circumstances5) All other parties involved (US,China,Japan,South Korea, Russia) are all to be blamed for suffering of 25 millions of people living in an artificial skansen of communism.6) Praising the great leader is one way how to protect yourself and your family when the "democratic, cool westerners" are not going to help you.

And the guy is openly preaching China for being much more advanced ? NK's regime is scary but the one in China is even scarier. They are pragmatic criminals that embraced the art of trade.

US and SK should have invaded and liberated the NK long time ago. They are as much part of the problem as the NK's leadership is.

Nice. Here is what I see if I just consider the pictures: very clean cities and countryside, disciplined and healthy people living their simple lives. People work and serve their country. Everyone is poor but equally so. No apparent inequality. People get education and perform arts. Of all poor places on Earth it doesn't look like it is the worst.

So this is how it looks to me if I put aside the usual "North Korea is evil" media context.

Finally, a reason to go into JavaScript development with a background in compilers! I can see the need for cross-compiling tools and certain special skills for performant web development in the future, especially since even with complete adoption of WebAssembly this will still create a split between browsers that support it and browsers that don't.

From glossing over the wasm spec, it seems it's designed for C++ compilation, which in the environment I do development, is totally impractical. It sounds like a TypeScript to WebAssembly compiler isn't on Microsoft's radar. In that case, it might be time to work on some tools for analyzing syntax and start annotating types, because compiling from ECMAScript to WebAssembly would be a great boon in production.

For all the complaining about it, I think I will actually be a little sad to see Javascript go. It wasn't perfect, but it had a powerful unifying effect on the Web Community when we could write, share and learn about our code in a higher-level scripting language that we could all read. (Even if there were some surprising little quirks that took a while to get used to.) Despite the stated intention from WASM - there is just something fundamental about AST trees - no matter how well you pretty-print them - that doesn't allow sharing and shared learning the same way. As a run-of-the-mill guy who makes my bread maintaining websites as much as greenfield-developing them, I feel like I'm in for a bit of a rough ride trying to decipher and debug binary/AST code compiled from Perl (or whatever). Guess I'll have to suck it up and learn to do it, though.

Would it eventually permit library sharing between, say, a Python runtime compiled to WebAsembly and JavaScript in the browser?

Because that would pretty cool.

Web Assembly should make code more portable and faster on the web. No more transpiling to JavaScript (which honestly is a hack; going from one language to another language which is then compiled). If you want to use CoffeeScript, even though I dislike it, you'll be able to compile directly to WebAssembly instead.

I can't wait until this is fully baked with DOM access, etc.

I think it's really impressive what Dell has put together here. As my old Thinkpad T430 is nearing it's fourth anniversary I have been looking for an upgrade for a while and compared different options with a focus on lightweight, powerful laptops with good Linux support. And so far the XPS 13 seems way more attractive than the new Lenovo Skylake laptops (e.g. the 460s), which have lower resolution displays (some models still start with a 1.366 x 768 (!) display, which is just ridiculous in 2016), less and slower RAM, smaller hard drives and -as far as I can tell from the specs- less battery life as compared to the XPS 13 but are actually 300 - 400 $ more expensive, even when choosing three year guarantee for the XPS. The only thing I don't like about the XPS is Dell's guarantee, which is "send in", meaning that I probably won't see my laptop for a few weeks if it has to be repaired, whereas Lenovo will send a service technician to me who will usually be able to repair the laptop immediately (I already had to make use of this service twice, once to exchange a noisy fan and once to replace a broken display bezel).

I guess I'll wait for Apple to reveal the new MB Pro line before making a decision, but it seems that for the first time in 10 years my next laptop will not be a Lenovo/IBM.

It's running Fedora fine right now but software management is totally different from my Debian-based experience. Might ditch it. ;)

It's nice to see Dell beginning to actually adopt Linux and Ubuntu. I always kind of figured part of the strategy of going private was to be able to move away from the status quo of being just another Windows vendor... By offering choice and eliminating lock-in, they can go after techie types and serious users who otherwise would have probably just bought a ThinkPad or MBP.

The previous models didn't support DFS in wifi 5ghz making them unable to work in high density wifi environments. Actually what's worse is that they randomically lose connection on a DFS AP (when the channel gets into one of the DFS-reserved ones they can't access). So you basically have to force them on 2.4 or disable DFS on the APs.

This applied to both the Broadcom and Intel wifi. Any chance these models are better in this regard?

This is great, but Thinkpads have always had good Linux support. I have a friend who bought the previous XPS 13 Ubuntu edition and it had all kinds of problems which are only being worked out now, problems that aren't present on most Thinkpads.

I got the X1 Yoga one month after it came out, installed an alpha version of Ubuntu 16.04 on it and everything just works, including the touch screen.

It is unfortunate that Dell chose to use small arrow keys and at the same time overload the arrow keys with the 'Home-End-PgUp-PgDown'. Hard to believe this layout was chosen for their Latitude and Precision lines too.

I suspect it has to do with two internal hard drives, but I've sort of given up at this point (I bricked the first box, and Dell sent me a new one) and relegate this otherwise very nice laptop to the accounting department to run Quickbooks and Office.

Since this is today's gun argument thread, I'll just point out that the UK is currently commemorating the 20th anniversary of its first and last "mass shooting" incident, at a school in Dunblane, Scotland.

The ensuing total ban on handguns and further restriction on gun licensing mean that mass shootings are nonexistant, firearm murders are extremely rare (about one per year in a country of 60m), shooting of suspects by police is extremely rare (police are not routinely armed, except for anti-terrorist patrols at strategic points with MP5s), and of course firearm accidents and suicides are less common as well. Sadly suicide is a problem in the farming community; farmers often have shotguns for pest control purposes and deer culling.

Terrorism is like a mosquito in a room. Hearing its buzz will drive people nuts but the actual harm caused is negligible.

But right now people are pretty much ready to throw their basic rights and freedom away in the hope it will make the buzz go away.

This doesn't mean toddlers are more dangerous than terrorists. It means there are more toddlers.

I don't think the internal logic of the argument works anyway. Do people react to terrorism solely because of the perception of present danger? I always thought terrorism was feared because it signalled that a group of people would prefer to dominate their host with violence than to assimilate into the predominant culture.

Increasing terrorism is a sign of increasing difficulties assimilating. The ultimate worry is that in 100 years our countries will be split into separate warring tribes.

Edit: Everybody is misunderstanding me. I'm not saying that "terrorists are more dangerous than toddlers!" or "gun control is bad!". I'm saying that people fear terrorism for different underlying reasons than its impact on fatality, and that understanding this will help communication between the right and left (perhaps allowing your arguments to be heard across political lines.)

To play devil's advocate, which gun law would have prevented this person from getting shot by her toddler?

As a gun rights advocate, she presumably has been around guns for a long time and should have been well versed in how to handle them safely. I doubt there's any training that could be mandated that would exceed the experience she already had. Short of banning guns entirely, which would require a constitutional amendment, I don't see what the proposed solution is.

She should definitely be facing some harsh penalties for negligence and endangering a minor if she isn't already. In general, I think it makes more sense to have laws that punish people for bad things that actually happen, not for things that might, conceivably, possibly lead to something bad happening.

No amount of legislation is going to prevent idiots from being idiots.

1. The source for this article is http://www.snopes.com/toddlers-killed-americans-terrorists/, which says

>Broad counts indicate that 21 toddlers shot and killed themselves or others in 2015; 19 Americans died at the hands of potential or suspected Islamic terrorists.

Even taken at face value, that's 21 to 19.

That page is itself a bit confusing. They count the number of deaths by Islamic terrorists while evaluating a claim that merely says foreign terrorists. The guardian then spins that into terrorists, not specifying foreigners. Glancing over https://en.wikipedia.org/wiki/List_of_terrorist_incidents,_J... and https://en.wikipedia.org/wiki/List_of_terrorist_incidents,_J... turns up the following:

https://en.wikipedia.org/wiki/Charleston_church_shooting, 9 deadhttps://en.wikipedia.org/wiki/Colorado_Springs_Planned_Paren..., 3 dead

Neither seem to be by foreigners, so snopes is not wrong, just confusing. The guardian is flat out wrong. The numbers are 9+3+19=31 versus 21 for toddlers.

2. The fear of terrorism is of the tail. People aren't that worried over the 10 people who die in an attack, comparatively. They're worried about the 3000 people that die for a large scale attack, even if it's less likely.

I bet if you took the last 25 years, terrorist deaths would be more than toddler gun deaths. If the latter is around 25 a year, we have a total of 625, versus 3000 from 9/11 alone.

What interests me about the gun debate (if one can call it that), is that there are ways of dying that are considered acceptable risks and ways of dying that are not. If you are driving your kids across town and get t-boned by a drunk driver and everyone dies, that is considered a tragedy. But no one will advocate giving up driving. Something really bad happened, everyone move on with your lives.

Or when a relative dies because of a medical error, they might be rage at the particular doctor at fault, but there isn't a general outcry against hospitals or doctors. Everyone will still urge you to go to the ER at first signs of a serious problem.

But if a lunatic shoots a few people in a public place, then guns should just be banned altogether and there is a general outcry and the POTUS needs to visit the victims to console them.

Maybe someone can enlighten me why the risk of gun deaths is so much less acceptable (to a portion of the population) than the risk of death by automobile.

EDIT: Skiing is purely entertainment. About 41.5 people die a year in skiing accidents[1]. This, too, is considered an acceptable risk.

Gun ownership is less about protecting individuals from other individuals, and more about protecting our society from governments that want to oppress it. You could make the argument that no such power exists today, but that's besides the point. Powerful, oppressive, nations have existed before and they could exist again.

This is more a reflection of how vanishingly rare either event is than a compelling argument for fewer guns.

In a population of 300m or thereabouts some people will die in some very peculiar ways. We can dig up some of the rarer ones to compare with terrorism.

That said some limitation of US gun ownership law does seem sensible. But this story is no more than gossip.

This will no doubt be framed as a victory for our Pro-Gun society.

After all, ubiquitous gun ownership has so diminished the rampant terrorism problem facing the USA that fewer people in 2015 were killed by terrorists than by small children. Compare that to, say, 2001, when thousands of people were killed by terrorists on average each month, and you can only see a victory in todays improved pro-gun climate.

Many people have rightly pointed out that terrorism, being a tail risk, should not have such an out-sized influence on policy or lead to the erosion of civil rights. If that is your take-away from this article, good for you.

Some people, including the article's author, then go on to argue that because of a different tail-risk (toddler's shooting people with guns) we should ban* all guns. This is a terrible argument. I am not saying there are no good arguments out there, I am saying this is not one of them.

*Yes, I said ban. Guns are already regulated, no proposed legislation would prevent this incident, and bans are the explicit end goal of most pro gun-control groups[1]

The statistics are always misinterpreted; they can't be considered in the same domain. Terrorists fall in the risk domain that is subject to tail events. Toddlers with guns don't. In plain English, you're not going to see a 10x increase in deaths one year from toddlers playing around with guns, while that's very possible with terrorist activity. In fat-tailed domains like terrorism, single, extreme events make up the entire mean, so just because something bad doesn't happen for a short period of time doesn't mean it's any safer. All it takes is one extreme terrorist event to do some serious damage.

Any discussions of guns in America that doesn't delve into the differences between states is bound to be uninformed just like this article. You want to see what gun control looks like in America? Go to New Jersey. We have gun control. You cannot leave your house in New Jersey with a gun. The laws and their enforcement are so draconian, you cannot safely even go to the gun range with your very legal gun. This is what gun control looks like in America. We have some of the worst ghettos and gun violence in America because we have gun control, because the only people stupid enough to have a gun on them in New Jersey are criminals. This isn't some hypothetical. This has been reality for decades here. So before some uninformed idiots make idiotic generalized statements about guns in America, I'd like to invite them to New Jersey and see how safe and wonderful their gun-controlled vision of America is.

No one could possibly make such arguments if they really considered the outcome of their actions, but most Americans are too stupid to do that generally and can only consider their own fantasies as reality. That's how we ended up in this situation of draconian drug and terrorism laws. Americans consider what they want to happen as what will and what is happening, despite a flood of evidence to the contrary. Then they write idiotic articles like this without even doing research and finding out what really happens when you have gun control in America.

When there's a researched, well-thought out article on gun control, maybe there'll be something to discuss. Until then, we're wasting words on both sides. Conversation my ass.

This is the latest in a line of articles (and arguments) for that matter that completely fails to address the gun culture we have in the United States. It paints a picture that people who have guns are just these crazy old hicks, ha ha look at them with their silly guns.

First of all in large areas of the country (and around the world) guns can be useful tools of survival or hobbies, including around where I live. We have shooting ranges, gun safety courses, numerous retailers that sell them, and no mass shootings either alongside a healthy and large hunting population. Guns are important here is the takeaway.

It's awfully sad what happened to Jamie Gilt and that toddler is probably going to have some serious issues to work out as they grow up, but let's be clear: she left the gun loaded in an accessible area. That was her choice and now she's paying for it.

Second of all, the problem with this article is that it's basing all of it's arguments in the rational. Guns are dangerous; yeah, we know, they're literal killing machines, that's what they're for. Guns are unnecessary; maybe where you live and we could get by without them too, but we don't want to. We LIKE the guns, that's why we spend large amounts of money on them. In Australia they made big steps in what many consider to be the right direction with a buyback program, but if that was offered here I can honestly say I wouldn't go for it. I bought my guns for a reason; I want them here.

You know a Toyota Camry would probably be much safer and much more economical and better for the environment than a Charger with a V8 engine, but the argument of safety, economy and environment completely misses the reasons I would buy the Charger; it's fun and I like it. And I feel it's an essential part of our freedom to make certain that people are allowed to choose what they WANT instead of what is necessarily the best decision FOR them.

Obvious answer: Ban toddlers rather than end-to-end encryption.

On a more serious note, the gun deaths in America are a cultural problem (being careless with weapons, not locking them away properly, etc). No ban will fix culture. There are ways of improving the world without bans. I loathe the kneejerk reactions like "someone was harmed by X - BAN IT FOR EVERYONE!". What happened to self-responsibility? Why can't we just educate people and encourage them to train in the safe handling of guns? It's not that hard.

A key promise of Obama's campaign for the presidency was to run the most transparent government- however the only person to really deliver on that promise was a whistleblower. Secret courts, secret domestic spying, and now calls for weakening of the digital equivalent of the safe shows that he either was not honest about transparency, or has radically changed his opinion since becoming POTUS.

Maybe it's that he decided to use his political clout to pick healthcare as his signature in American history, not wage war against the NSA, but either way it saddens me to have campaigned for someone who has empowered a surveillance state instead of fight against it.

Liberty literally means "freedom from arbitrary or despotic government or control", and freedom in the information age means the liberty to communicate and store information. Anything to compromise that makes us all more vulnerable to control in all parts of our lives, not just those stored in zeros and ones. I believe America can be "Land of the free, home of the brave", but not without digital liberty.

Mr. Obama, you are the one who upset the balance with secret, dragnet surveillance of nearly all communications. That's not the bargain the public has had with law enforcement for the last 300 years. Widespread, end-to-end encryption is simply the natural reaction to the arms race you started. We would have never come to this point if the government had kept surveillance within court-supervised bounds.

Obama has a meta-point however that proponents of the absolutist position don't seem to want to face. Democracy relies on transparency. Many of the progressives who are rallying in support of absolute right to privacy are some of the same people who constantly criticize Swiss bank accounts, Cayman island financial shenanigans.

But if companies were to implement the same sorts of impenetrable encryption, on every device, all the way down to the corporate desktop, in a way that not even the company executives themselves can read the email of their own employees, then lots of regulations the government applies to companies would be mooted.

Taken to the extreme, if all communication is digital, and 100% impregnable, and people maintain good OpSec, then it will be hard to impossible to execute lawsuits or regulatory investigations into malfeasance because they'll be no paper trail.

The end result of going full tilt on crypto is cryptoanarchy. This was pretty much well argued in the 90s among the cypherpunks community. Most of the libertarians and Objectivists were salivating over how strong crypto protocols would end fiat currency, end taxation, end regulation, and so on.

So how far as a society are we willing to take this? Does it just extend to private data? Does it extend to transactions? To payments you make for things? To transfers of money? To business transactions? Will Democracy be able to audit nothing of the interactions of citizens or our institutions in the future?

You don't have to agree with Obama's position to see that cryptoanarchy and Democracy are on a collision course, and it makes sense to discuss the possibilities openly without just plugging your ears and taking an absolutist position that demonizes anyone who disagrees.

Privacy will die, not because it's undesirable or a bad idea, it'll die like copyright and DRM - because it's technically and economically easy to defeat, and people will be motivated to do so.

In the end, they are going to introduce laws that make it illegal to implement end-to-end encryption. This sucks, but it's going to happen. France is already moving to do it [1], and in the US, John McCain and others are also calling for similar laws [2]. They will all start off saying that it will be controlled carefully etc., as Obama keeps saying, and then it will be used with reckless abandonment.

What this essentially means is a move to Android for criminals, terrorists, and anyone that wants privacy (since Android allows installation of apps that have not been approved by a gatekeeper bound by the laws of the countries it operates in, whereas iOS does not by default). Open source Android apps with strong encryption will be built in countries without such laws. All of this will likely be the downfall of a few lazy drug dealers that don't want to give up their iPhones, but since the cat is out of the bag and apps with end-to-end encryption already exist and will continue to be built, the governments making these moves will not actually catch any reasonably intelligent terrorists that install and use these apps. They will, however, gain exactly what they want: the ability to conduct surveillance on most people in the world whenever they want.

This is akin to the politicians that don't want to believe the science around global warming. They believe that if they just deny it, they will turn out to be correct. Obama is doing the same with "golden key" encryption. It is not that the experts are correct and know what they are talking about, it is just that they are disengaged and being stubborn.

"I'm the President of the United States of America and if I say that there must be math that gives me what I want. If you don't invent it, you are disengaged."

If law was adopted to require backdoors - those who are privacy conscious would simply move their data to countries that allow for strong encryption as well as deniability.

It'd still pose an issue for when people are accessing their data, however depending on your setup this will be very hard to prove from a third-parties perspective given ample security precautions taken (ie using an offshore VPN all the time, data never full accessed locally).

For larger tech companies, I'd assume setup of a new company structure offshore and sensitive data handling to be "outsourced" offshore too (ie parts of the EU, other OECD countries).

I hate it when leaders get all upset when the balance is shifted away from them, and yet are perfectly fine when the balance tilts in their favor.

FTA: "then that I think does not strike the kind of balance that we have lived with for 200, 300 years."

200 years ago, it was not possible to cast a dragnet and catch everyone who was doing Something Bad(tm). The government had to get a warrant to open mail; today, the NSA can sift through billions of messages (metadata, they say) in a second.

Even considering US Mail: you could not keep track of who was sending whom mail, at scale. But today, every letter that is mailed has its front and back scanned (for reading the address); but more importantly, these images are saved for future use.

All of this is possible thanks to technology. And when the balance was tilting in their favor, the Establishment was quite happy. But when the balance tilts the other way, suddenly they're crying like a spoiled child whose toys have been taken away.

You can't just throw tantrums when things don't go your way. If the technology permits E2E encryption, they'll just have to live with it and find other ways to catch criminals.

All this talk about "warrant-proof spaces" presumes that they're something new, when in fact they aren't. In the past, conversations in private tended to not be reduced to tangible form and were lost to law enforcement unless they had the foresight and the warrant to bug the location. Now that so many of our communications are mediated by technology, they are by necessity reduced to a tangible form. Secure end-to-end crypto merely takes us back to the status quo antebellum.

Let's get the facts straight about encryption and security. The DOJ needs our help, and we need theirs

We need a grassroots movement here. I know we have the EFF and Apple and a slew of others. But we all need to be writing about this to have our voices heard.

I am in between projects and writing about this extensively online. Would anyone like to work together to organize facts and promote discussion in a concerted manner? The goal would be a) to make a concise message that is understandable by a non-techie, b) back it up with facts and primary source, and c) seek out public figures who can share our message. I have a running summary of events here which I will put in a github repo [1]

Dear technologists:

The task of educating the public and our government on encryption may be even harder than you think. Everyone needs to understand the issues at stake in order to make up their own mind, and it could take years to educate the general public about encryption.

We can expect to continue seeing terrorists attacks in the news regardless of what laws Congress passes. This much we know, and this is, of course, out of our control. However, uninformed law enforcement will blame encryption and they will blame technologists for not allowing them to catch these attacks. Unless all law enforcement truly understands the technology, then they will always blame citizens for fighting for their right to privacy.

Of course, we know this is about security vs. security, not security vs. privacy. Privacy is a secondary focus for many. But law enforcement believes our primary focus is privacy.

My primary concern is that law enforcement does not know how to keep us safe in a world where criminals can sometimes communicate with smartphones across the world in a way that cannot be monitored with a warrant. Regardless of whether Cyrus Vance, James Comey, Loretta Lynch or Obama truly understand this or if they are putting up a smoke screen, the fact is that law enforcement across the country trust them the most. Non-technologists will be more moved to understand the security and economic implications of forcing backdoors upon Americans and US phone manufacturers. For the most part, they are not going to see eye to eye with us on privacy concerns. Lindsey Graham has already changed his view. We can share facts with others and let them make up their own minds.

Some damage is already done. The fact that Vance and Comey have been fighting this for so long is going to make it difficult for them to go back and convince officers of the law that technologists were right, and they were wrong. Many officers will continue to feel snubbed by the tech community.

If we're to advance to the next level of our mutually trusting society, we must all understand encryption technology and its implications. To the extent that we do not all understand encryption, and the ease of which it can be used regardless of government mandates, we will continue infighting and not progress together.

The idea that technologists feel the issue is black and white or absolutist is absolutely incorrect :-). Math is black and white, but our public safety and security is not. It is a complex equation that must be balanced, and we have that focus just as President Obama does. The difference between us and the DOJ is we understand a few more pieces to the equation. I'm open to the idea there are pieces that technologists do not know about, and I encourage the administration to share these details with us. Until all the details are on the table, we won't be able to come up with a solution together. Let's focus on discussing and sharing the variables and their weights. Given information, people can make up their own minds.

If backdoor laws are passed, it's not the end of the world, but our industry will suffer while non-technologists struggle to understand why terrorist attacks continue to occur. It'll be another 4-8 years until we can dig ourselves out of that hole. Let's keep the great country we have and bring facts to the table for open discussion.

This is incredibly naive bordering on puerile. To suggest that POTUS' view on this is without nuance is to miss his point. POTUS went on to cite existing warrant mechanisms and their underlying principle:

"And we agree on that, because we recognize that just like all of our other rights ... that there are going to be some constraints we impose so we are safe, secure and can live in a civilized society."

I'm not suggesting that this means POTUS and the government have the right answers at the moment. Despite that, we can't ignore the important role law enforcement plays in society, the requirements in support of their role, and the complexities surrounding the right to privacy. We need people advocating for the right balance, not just getting each other frustrated.

OP may have worries other than US law enforcement being from another country. This is one of the /many/ complexities in this space.

I think a lot of libertarians miss the fact that many of the communications monitoring aspects that the administration is proposing includes authorization by court order.

It's not like your communications are being monitored by random government employees at will for no reason. There's a specific safeguard here for personal privacy, and that's through a court order.

If government is monitoring your communications, then there's a pretty dammed good reason, as determined by a judge.

Sure, you might call that final safeguard as not enough or susceptible to corruption, but once you do that, you cease to be able to function in a society.

Judicial review is the "trust zone" that citizens are expected to have on society. If you don't trust judicial review, then there's no hope left for you to function in a normal society filled with other people. If you don't have such a "trust zone" in government, then you are basically forced to build your own army to protect you, since you don't trust government.

Since having your personal army is stupid, your best option is to make sure judicial review cannot be corrupted.

Can someone explain to me why universal basic income seems to be more popular than negative income taxes these days? To use some examples I'm picking out of my hat:

1. Universal basic income: Everyone gets $10K per year.

2. Negative income tax: Everyone gets $15K per year, phased out linearly across an income of $60K (i.e. if you earn $0 you get $15K, if you earn $20K you get $10K, if you earn $40K you get $5K, and if you earn $60K then the negative income tax is fully phased out).

Why is 1 preferable to 2? Is it just that it's less susceptible to tax fraud? Note that the amount that an unemployed person gets in UBI is less, because the same amount of money is being distributed to more people, even millionaires.

While I can understand the benefits of basic income, it still bugs me that this might massively undermine democracy and turn out to be a point of no return for a society. Once every single voter has an incentive to vote for politicians that promise increases of their basic income, each election will turn into a competition on increasing that type of spending. It's basically a massive redistribution scheme. This is different from welfare systems, which only support a small number of people who actually need it.

This basic income idea has been popping up a lot lately. And there's some merit to it, but there's some major problems too.

The biggest problem I see is giving people cash. Why not instead give each adult a voucher for housing (just barely adequate for cheap housing) and each person $5/day food stamps (or something similar), regardless of income.

Everyone gets a lower stress level this way. The risk of being homeless or hungry go to near zero. It doesn't matter if you're unemployable, or starting a business, or between jobs. You know you're going to be okay.

While giving people cash seems to have the same effect, it doesn't. At least here in the US, money problems are (mostly) a money-management problem. Many people use any cash they get to pay for whatever seems the most pressing at the moment - whether it's rent or a big screen TV. People buy the TV when they have money and rent isn't due yet, then have a little unexpected expense and can't pay rent. The stress level hurts them, hurts their families, causes increased expenses (e.g. payday loan).

My parents were like this, in six-figure-income years and in dead-broke years. It hurt us quite a bit. And "loaning" them money NEVER helped - they'd pay the mortgage today and then buy the TV when the next payday came in. And there's LOTS of people like this, which is why there's a payday loan on every corner.

Now, we've taken care of my mom by covering her housing and utilities directly. And her stress level is down a lot. It works great. This would have also helped me a lot when I was a student. And it means more startups - since all startups would be "ramen profitable" by default. And in the US, we could fund this with about a 10% tax (probably less if we took some funds out of SS, disability, section 8, etc.).

I'm from Montreal where there's already income to families not making enough money. This is great but obviously some people abuse the system and use it to drink beer all day so some Montrealers don't like the idea of using their taxes to give them money.

But one very important point that people don't know is that giving basic income like that, even if abused, reduce criminality. When you have no money and are desperate, you're more likely to start doing illegal actions. Economically speaking, when you start thinking about the cost of more criminality, you realize that it's a pretty good deal to give basic income.

Not everyone here agrees with what I just said - most people don't even know that - but I think that in itself is a great reason.

The title of the article is completely misleading.

http://www.fin.gov.on.ca/en/budget/ontariobudgets/2016/ch1e....

From the Budget:>One area of research that will inform the path to comprehensive reform will be the evaluation of a Basic Income pilot. The pilot project will test a growing view at home and abroad that a basic income could build on the success of minimum wage policies and increases in child benefits by providing more consistent and predictable support in the context of todays dynamic labour market. The pilot would also test whether a basic income would provide a more efficient way of delivering income support, strengthen the attachment to the labour force, and achieve savings in other areas, such as health care and housing supports. The government will work with communities, researchers and other stakeholders in 2016 to determine how best to design and implement a Basic Income pilot.

I find it quite interesting they are presupposing a Universal Basic Income, will strengthen attachment to the labor force instead of decreasing it. Human Nature suggests other wise.

I think there's a real opportunity for a grand compromise between the left and right here. If a basic income/negative income tax is bundled with abolishing most or all other government handouts and retirement plans, small government minded people like myself could get behind it.

One thing I worry about is that this could cause massive inflation and a recession (stagflation) as people drop out of low-wage work in droves. What percent of society will decide to live on solely the basic income if it's high enough to pay for basic expenses? Work is virtuous and builds character. Idle hands are the devil's playthings.

And what would it do to our democracy if a huge portion of the population is living on someone else's dime and not even trying to join the workforce. Isn't it fair to call them children? What insight could they possibly have in the democratic process except to vote their own immediate monetary interests? I believe in universal suffrage, which is why this is a conundrum for me.

The issue with basic income is in the long-term. When more and more generations of people start to depend on it (I've seen it with welfare in my hometown), it becomes a crutch and will stifle their future success.

Eventually, there won't be enough people giving back into the system and the whole thing will collapse. Before this happens, taxes will continue to be raised in people in lower income brackets.

The politicians love it though. It creates an instant voter base. Why would a person, receiving free money, vote for someone that will take it away?

Because of things like this, I wish we had laws in place that all voters had to at least 1) work some sort of job (it doesn't matter what it is) and 2) proof they paid income taxes.

While I spent more than eight hours on both puzzles, I found them to be thought provoking and I learned stuff in the process so I don't feel like I wasted any time and I got a check in the mail for $200. My code was reviewed by their dev staff so they had immediate feedback on my programming ability and high confidence to bring me in for an on-site interview.

If an applicant wants to apply for a job they have to write code in the language of their choice to apply using the API. Upon successful application, request their SSH public key and supply a git repository they can check their code into. A hook script will email me upon successful commit.

A moderately experienced dev will not spend much time to apply, and frankly would probably enjoy the interface better than most job application websites. :-)

A lesser experienced dev will end up spending more time, but really if they are successful we would still want to look at them.

A couple of months ago I did a 'homework' assignment for an interview (it involved writing a simple REST service in go, even though I have at least one personal project demonstrating exactly this skill -- to an even greater degree -- in my github profile). During the phone-discussion after turning in the project, the mid 20-something lead developer couldn't find anything to nitpick (I could have) and even told me he thought I was a better programmer than him. The conversation went very well and I felt confident I would receive an offer.

Now, what do you suppose happened next? I never heard from them again and all of my attempts at communication were ignored. I'm starting to think my age is becoming a factor (mid 30s) -- and also these kids have no sense of respect and professional courtesy. I'd like to say this was an isolated incident, but that would be a lie.

Stupid me just spent his Saturday doing another such project, though at least this one presented a more interesting problem. I swear, if I find out I had my time wasted again I'm going into consulting. Or maybe I'll go to truck driving school. Or open a cafe. Screw this "employee" stuff.

The fact that so many employers treat candidates like this tells me that the whole "it's hard to find good developers" line is a lie.

I definitely wouldn't call myself an expert, but in my career I've probably interviewed a few hundred people. I think people way over-complicate this stuff by trying to be too clever.

To me, the most useful question is this: "here is an example project that we'd be likely to do, how would you build it?" Then you just let them walk through the steps they'd take.

From there you can launch into why they made the choices they made, trade-offs, philosophy, etc. When you hear people explain how they would make something real, you start to learn a lot of things about them without even needing to ask, and so you're less likely to get scripted answers. They're also probably in their comfort zone at this point, so you get to see them in a more real way.

I don't necessarily mind "homework" style projects, but I tend to shy away from that sort of thing as it's not always respectful of the candidates time.

Two questions I usually avoid (but see getting asked all the time): puzzle questions, and language trivia. I don't ask puzzle questions because I've never seen it correlate to something useful. Most puzzles require an "aha" moment where your subconscious bubbles up some kind of answer, but the easiest way to short circuit that part of a persons brain is to put them in front of strangers with a time constraint. Puzzles might give you a clue as to a persons overall IQ and confidence, but it won't tell you a lot about how they can do the job.

Puzzle questions are also "expensive", in that they usually put a candidate on edge, and they set off the candidates bullshit detector. Let's keep in mind that we're going to reject the majority of candidates, statistically speaking, but you still want them to think highly of your company. If they feel like they're being rejected for a BS reason, you've just created animosity towards your company. It's important that the people you reject still feel respected.

I don't ask language or framework trivia, as I don't think it's useful. I might lob a softball about a framework just to make sure they've actually used it, but I'm not going to ask something hard.

The real problem here isn't coding interviews; its how we (hiring managers) approach the entire question.

The goals of a technical interview should be:- Confirm the credentials presented aren't complete BS- Validate they know enough to be immediately helpful- Assess their long term potential (brains, social skills)

Coding challenges tend to be good at the first two points but very questionable for the third. Incidentally, given that I'm seeing a 50% washout rate from a basic SQL code question (supported by confessions from candidates that they fabricated credentials/experience), you would be silly not to include some form of practical test.

The third point (potential) is best measured by talking with them about a project they really cared about. For those who cannot share work examples, pick a good side project. Don't get hung up on the content - focus on their passion. You'll get a better view of my capabilities if you chat with me about building an ad server, mobile optimization, or SEO analytics (real world projects I care about) than with a contrived example.

As for the github profile of code shrugs why? Seems like a bit of a cult to me. I'm happy to sharing anything that's useful (and do so on my blog) but don't have the free time to spend developing code for the sake of "work samples". My work samples run on production servers as commercial projects, thank you very much..... Suspect many other good candidates are the same.

Sorry but I will not write any code for you.

Furthermore, after providing ZERO feedback in the past when I have provided github links, offline code samples, personalized cover sheets, etc. to prospective employers this also will not be done. I'm not going to worry and beat myself up because you can't be bothered to provide feedback even when requested to do so.

Homework for programming jobs is just like homework for school: it is not used to judge competency but to demonstrate that your time is not your own as it belongs to someone else. In the case of programming jobs the homework assignment also acts as a filter to weed out employees who will not be properly subservient to the employer.

I am in the midst of my job search, fortunately I'm not currently working (due to an international move) so I have more time.

So far, I have completed around 12 1 hour phone coding tests, the same amount of 30 min chats with recruiters, I have 8x 5 hour on-sites scheduled, have spent about 4 long days on one take-home assignment, 6-8 hours on another, and have two more assignments to complete, both of which I estimate will take over 8 hours each.

I haven't had a weekend for the past 2 weeks because I've been working on assignments and I'm pretty stressed and exhausted.

This process has made me consider changing careers because it's so exhausting. When companies give you take-home assignments I don't think they realise how many things you have going on at the same time.

Additionally, I've found that a one hour coding test has allowed companies to move faster in the process with me than those who have given assignments. When I receive an offer from a company I am happy with then I will tell those companies with assignments I haven't finished that I won't be moving forward with them and they will miss out on a great candidate!

On paper (or blog), having a candidate write code for an interview is better than a BS whiteboard session.

In practice, it means I spent 20 hours on my last piece of sample code I submitted to a job I was excited about. Only to be told no thanks, with the feedback of:

"Your app meets what we spec'd out, but it differs from our style."

And to be clear, after I repeatedly asked for what they were looking for in this code, they replied "we are purposely providing nothing except functional requirements to see what you produce".

I could have given them exactly what they want, but I guess they'd rather just wait and hope that someone magically codes the same way they do?

Honestly I should have billed them after that.

Last week, I finished 2-3 hours of on-site interviews which required a flight and an overnight stay after an initial phone screen, a phone technical interview, and a short technical challenge online.

I was surprised how a couple really basic concepts evaporated from my head during the in-person white boarding. The questions though were reasonable and the interviewers were friendly. All in all a positive experience just an incredible investment of time it seems for all concerned.

The take away is I need to practice solving problems on a white board with just 3 hours of sleep. The sleep deprivation part might be the most important factor to simulate.

Hm. Maybe bourbon? Or a good cider?

Like the author, having run a hiring program for several years based on coding challenges designed to mimic the work the team does (ie, work sample tests), I do not understand why any tech company does developer hiring in any other way.

I particularly like how this team iterated on their uploader problem, abstracting it out to a socket server and providing a test suite for it. Reacting to ambiguity by abstracting the problem was clever. And, of course, a great illustration of how a standardized hiring tool can, like any software project, be iterated on and improved --- unlike a free-form whiteboard interview.

I think the reason so many companies resort to asking candidates to do a programming project for the interview is because they are lazy and don't want to take time to interview someone, or they suck at interviewing, or both. Bottom line, if you can't judge someone's ability by talking to them it's YOUR fault. You suck at interviewing. Last time I was looking for a job a company I was interested in gave me this massive assignment and I just told them to take a hike. I'm not spending all day writing some code for you for free sorry. Sure there are lots of horrible programmers out there, and you'll end up hiring them if you suck at determining what their skill level is via a conversation. But I hope other GREAT developers follow suit with me. Refuse these stupid programming challenges.

Is giving out an 8+ hour programming project as part of the application process really considered good hiring practice? If you apply to five jobs, you're expected to spend an entire unpaid work week writing code that doesn't benefit anyone? If a company receives 20 applicants, their ideal candidate selection wastes a collective work month?

I don't really understand this ideal. What's the point of maintaining an online portfolio and a github profile full of code if companies prefer to waste your time writing a pointless uploader?

A lot of people here seem to suggest it is unreasonable to ask someone to do some coding in an interview given that you've shown a series of projects and provided references. Unfortunately I've been through a variety of interviews where I feel the conditions which I was asked to code were unreasonable (whiteboard, overly complex problems while under pressure, using a language I was not comfortable with or just academic problems that are rare in the real world), but I really think confirming their ability to write code, beyond things like github repos etc, is an important step of hiring a developer (because i've seen great github repos and references, but ended up with developers that are very, very average)

I've only hired tens of people, and while that is not a massive sample size, I'm still astonished by the simple questions we ask that people get stuck on. The one that continues to shock me:

"In any language of your choice, write a function that takes an array of ints and returns the sum of those ints (If you use a language such as php do not use array_sum)"

I'm just looking for something like:

function sum($ints) {

 $sum = 0; foreach($ints as $i) { $sum += $i; } return $sum;
}

Then we follow up with something like: "lets say your input array contains [4,-7,0], walk me through the code"

And we finally ask "talk to me about some things that could go wrong at runtime that might cause issues with this function". Expecting people to talk about overflows (maxint?) or if its a dynamic language like php, checking for non-integer values.

I estimate that around 50% of people get ruled out during the "coding" exercise mentioned above. It is astonishing that these people even apply for developer jobs.

I can see the value from a hiring perspective in asking candidates to code, but it's no panacea. The bias in the interviewing process that so many acknowledge still bleeds through into many of the coding projects in the form of prescribed languages or frameworks. I suppose there's some merit to that if the intention is to screen for experience in a particular language or framework, but it does run counter to the commonly-expressed sentiment that companies are looking for smart developers who are able to learn new technologies rather than developers who have happened to use particular technologies.

As a candidate going through the job search process now, though, I have to say that it gets tiring to do a project or programming test for every different company. I can juggle more traditional applications (phone screens, on-site interviews) at a time than applications that require coding projects as I'm limited by the number of 4-hour (or 8-hour or whatever) blocks of time I can devote to completing a project for each one.

I think a coding test is the wrong approach. Typically a coding test is too simple to be meaningful, or too difficult to be practical.

Instead I would have a Mock PR in a github style discussion forum. Have it be a contrived example of some things that could be improved or some things that could spark really good discussion. Give the mock PR link to the candidate and ask them to Peer review the code. Make the discussion and comments of the the candidate the basis for which you determine their aptitude. If they have a lot of depth in their critique then you can be relatively confident how they would interact with the team in a real work scenario.

If a company asks me to do 8 or more hours of artificial coding test I usually refuse, unless I really want to work for this company (because it is well known in the community, which are few).

However, I'm happy to work on any real task for a reduced or limited fee. It's a win-win: the company gets to know the candidate under real conditions, has an actual task solved at a reduced price, and the developer does not give away his/her time for free. Plus, if it works out, the candidate has learned already the first steps about the company's system and process and can directly build on it.

I'm always wondering why not more companies do this.

I just instituted a coding assignment with our hiring (exceptions made for those with extensive github/similar open source contributions), and so far only have had three candidates do it, but I'm a fan.

Mine is crafted so a really competent developer could get it done in 30 minutes, and intermediate 2 hours and a junior probably not finish. I tell them to send what they have in after two hours that I'm as interested in seeing the structure and thought process than the final result. It seems much better than having someone do it at the office or one a whiteboard for accessing basic competence.

Yes it sucks, but after you get bit once or twice by hiring people who knew all the right words but can't actually produce something useful you get a lot more open to it. I'll gladly take the time to take you out to lunch to discuss the job and code assignment and give feedback afterwards, investing a couple of hours into finding your next job shouldn't be this huge ordeal and gives off a diva vibe I don't want in my organization anyway.

Calcado describes his wish that the candidates be "more T-shaped", and not just worker bees with narrow skills. But I see no mention of ways his more successful hires "branched out" and expressed wider interests or capabilities, presumably in in domains outside computing.

Here, do the T branches apply only within computing, like knowing more than one software tool? If so, I think that's not what Tim Brown meant.

Presumably an interview seeking signs of "T-branching" would propose higher level questions, like business acumen or domain curiosity or spontaneous Q&A to better understand or elaborate the requirements needed to solve a representative problem. Otherwise the "T" just equates to broad software skills.

The process I've seen working best to this day was at Pivotal Labs: pair for a half hour to one hour with 3 different people in the team you're being hired for. You get to measure everything, from communication skills to cultural fit. Perhaps pair on an internal tool, or even better, an open source project (in which case the candidate gets an extra incentive for not wasting their time).

If you're dealing with too many candidates, issuing a simple 1-hour coding challenge will weed out the uninterested (and won't favor people that have 4-8 hours to devote to a huge coding challenge).

not sure why there is so much resistance here about doing an 8 hour test, I might be in the minority but for a traditional whiteboard interview I would spend a lot more than 8 hours revising algorithms and so on, and have a lot of stress due to whiteboard coding not being anything like real coding.

Being able to take a Sunday to work on a challenging problem in my own editor / computer / dev environment sounds great! I wish that all companies added in their job ads something like 'if you want to skip the whiteboard send us your solution to this problem together with your resume' where the problem is a representative problem of the type of work they do, then you spend the interview discussing your solution as opposed to playing algorithm-roulette.

It would also cut down the uncertainty when you see a job ad where they ask for all sorts of different languages / skills, if you have fun doing the coding test, it's likely you'll enjoy working there, and vice-versa (in which case you might decide not to even apply)

A few years ago I was given a programming test after an initial phone screen with a HR person. They said do it in any language, and it had a fancy framework that let you edit and test the solution before you sent it.

I chose Clojure since I was learning it at the time. The problems were easy and I made working solutions, but the framework wasn't working. I gathered some call stack data and sent it to the people that make the tool. They thanked me for the feedback and later fixed the bug.

I sent the completed code by email to the company with a note about what had happened. Showing clearly that my code works in the form of some tests.

Then, on the basis of this they didn't proceed.

I've only had to do 4 of these, as they aren't that popular in my corner of the earth yet, but I didn't like them, I have a kid and stuff to do and I can't spend my time doing 4 hours extra on the weekend unless it is a job I really, really want.

First out of the 4 I did what was asked but got refused because I didn't clean up the code afterwards ( I thought I'd been cool for demonstrating some lesser known functionalities of the language and API I was dealing with). If I've spent 4 hours doing it, I don't want to spend 2 hours making it really pretty.

Second out of the 4 I misunderstood the instructions so I went in and 'fixed' their code to make it work they way I thought they wanted it ( was maybe too tired since it was late at night after a day of working on a personal project) This was actually a job that was close to one I really, really want.

Third out of the 4 I can't remember anything about it now.

Fourth out of the 4 they really liked what I did and we had a great interview, and then I got turned down because they thought I wasn't really that interested in their company (which was true, I was just fulfilling a job search requirement while getting my startup going)

Aside from that I interviewed at a social analytics startup one time and we ended up talking data mining and they asked me to do a 2 weeks project with them to do a POC of sentiment mining Twitter/Facebook. I gave them what my consulting fees would be, but they seemed really interested in me doing it for free as conditional for pursuing employment there. So I never got to try that coding exercise.

Well, you cant give people stuff to do offline because they cheat (youll see the whole thing show up in no time as a Stack Overflow question). And you cant avoid coding questions during interviews because it is astounding how much people lie on rsums; seriously, even people who describe their background as Advanced Knowledge of $LANGUAGE, can choke when asked to do the most trivial things in $LANGUAGE.

I try to ask questions that arent completely ridiculous, but definite tests of knowledge. And in my mind I judge correctness not so much on remembering obscure syntax but on how they approached the problem, and how much time it seemed to take them to start doing something. I always ask about things like how they approach debugging, testing, etc. because these are important too and they tell you a lot about how likely the person is to be able to handle any problem you come up with.

> we would ask you to use just your languages standard library, no third-party libs or frameworks... With the problem description, we sent to candidates a functional test suite, a binary that when started would try to connect to the candidates server implementation, open lots of sockets, sends lots of messages, and verify the results against what the problem description stated. The candidate was instructed only to send their submission once it passed the functional test on their local box.

Incidentally, this is exactly how the "Sun Certified Java Developer" certification was structured. You were only allowed to use java.* and javax.* packages provided as part of the JRE, and even among those things like the SQL packages were off limits. Instead of sending a test suite, they provided an interface you needed to implement and then when you submitted it, they had some sort of test suite that tested your code for conformance to the spec (and if it failed, you failed). If it passed, someone would manually review your program to make sure it made sense with respect to the requirements (which were intentionally somewhat vague, like real requirements) and if you passed that step, you had to write an essay about WHY you made certain design decisions (like sockets+serialization vs. RMI, etc).

This was by far the most challenging and fun task of its type that I've done, and to this day if I see that someone has that certification I know that they have what it takes to get things done. This methodology should really be utilized more, although for many companies the overhead of designing such a challenge would be way over the top. Makes me think that things like https://www.stockfighter.io/ have a future in our industry.

As I mentioned in another comment on this thread, one of the biggest issues is framing programming as a low-status, commodity activity.

I doubt Digital Ocean does this since they want good people, but a lot of firms absolutely design their hiring process to create an upper hand and lower your status before you even walk in the door -- especially if you're an experienced engineer.

Short timed tests or whiteboard hazing are the worst version of this. These are the most blatant attempts to commoditize software labor down into a fixed set of "primitives" like data structure trivia or riddles. This is what organizations like HackerRank exist to do: allow big companies to suppress wages by creating these sorts of commodization filters. They don't attempt to capture the value of creative problem solving at all -- because the company is not pricing the value of creative problem solving into the budget for the position, since it's a rank-and-file commodity job.

For this reason alone, you are better off flat out rejecting anything like a HackerRank test or similar online, interactive, short timed test. I would absolutely go so far as to even refuse to write code on a whiteboard if asked to do so in an in-person interview. It's fine to talk about how to solve a problem and spec things out. But the minute it becomes focused on actual fucking syntax, it's game over. You are now a cog.

Longer-form tests are a lot harder to evaluate from the candidate's point of view. Now you are asking for a significant chunk of my time, without paying me. And I am still at the mercy of whatever you happen to think constitutes a valid test. I might look at your take home test and thing, "wtf? this has nothing to do with real world work." Where does that leave me? Of course I want to impress the hiring staff, but I also don't want to get roped into a bad job, and a team that hires me to do real world work by using contrived coding examples is probably not a good place to be.

Personally, I think it's a lot more useful to talk about code that already exists. Either example code form the candidate, or example code that you give to them along with some time to study it.

Engineers read code more than they write code anyway, and right when you hire someone, even if you're a bleeding edge start-up, their short-term impact is a lot more predicated on their ability to read code and quickly learn a new system, not so much writing a bunch of stuff from scratch.

It's also pretty hard to fake competency when reading and discussing actual code. If you don't know how something works, you just don't know. You probably can't just google how the internals of some highly-specific ad hoc code works, unlike data structure trivia (which is yet another reason why it just doesn't matter how much data structure trivia you have memorized).

Basically, my overall conclusion is that when someone asks you to code in a short, timed setting, they are basically lighting a cigar, fingering their handlebar moustache, kicking their feet up on the table, and saying "dance monkey dance."

Unless you are literally desperate for the job, you should reject it right away. You are being positioned so that no matter how well you do on the test, you are but a lowly code typist and they will not take your attempts at negotiation seriously.

I understand the appeal of having candidates write code as part of the application process, but in my view it's useless and worse, it will drive off some of the best potential candidates you could get.

First, why is it useless? Because it is an artificial and contrived exercise and not real work. Even if you design your requirements to mimic your real work environment, there's something key missing; the candidate has no knowledge of your team and your environment. How I would write code for my current team vs. how I would write code at any other job I've been at is different. You're basically asking the candidate to take a guess at what kind of paradigms your code reviewers like and what they don't like and hope it works out. One team might find use of closures smart and great, and another might find it unintuitive and adding unnecessary complexity. Your applicants have no way of knowing and just have to hope they write code your team likes.

On top of that, one contrived exercise is not a good way to get an idea of a persons' actual skill and knowledge. I'd much rather have a 30-90 minute conversation with someone where nobody writes any code than to review a contrived example. I get the appeal of the programming task, it can be done asynchronously and thus doesn't require any developer time until you go to do the review. But is it really saving you much time? Anyone who's code doesn't pass unit tests or any other automated level of screening wouldn't probably make it very far into a conversation either.

If I have an applicant spend 1-4 hours writing a code example I've had them use at least as much and probably more of their time for far less benefit than if I had simply called them up on Skype and talked to them about programming. The conversation will reveal not only a lot more to me about their actual skill set, but also their personality and how they might fit into my team. Now I realize teams doing exercises aren't skipping the conversation step, but I'm advocating for skipping the programming task step and going right to the conversation if someone's resume is solid and they can intelligently answer some basic questions (a handful of questions that should take no more than a couple minutes to answer, not an essay.)

Second, why would I say it drives off good candidates? Because I know a lot of really good developers (including myself) who skip any job posting that requires writing code as part of the application process. Why do I do that? Because it tells me the team behind this application is immature. They haven't yet gotten to the point in their careers where they realize these exercises are a waste of everyone's time. That means there's probably going to be a lot of other young dude bullshit in the team that I'm not interested in dealing with.

This will sound moralistic, and I don't mean it that way, but I think this relates to our general lack of clear values as a society. With religion absent in many people's lives, not much has stepped in to take up the slack and say "what really matters is being a good person" or "what really matters is wisdom" or "what really matters is family". So we're left with the messages we ARE getting, which are from a combination of advertising (what really matters is having a lot of money/nice things), Hollywood (what really matters is being good at shit) and the news cycle (which focuses on careers and especially major careers). "Mom gets home from work and has a fun late afternoon with her kids, spending no money and getting nothing much done" isn't a story we ever see upheld as a great, positive way to spend our time. So we pursue the things we do see people praising and talking about - promotions, money, milestones, important-ness.

I moved to SF in 2008 as a poor college grad. Since then, I've spent all of my time in startups. It's an unhealthy addiction and it's going to kill me.

I was the third engineer at Eventbrite, and I spent years working many extra hours. After 4 years, it felt like I worked 10 years.

I quit and moved to Europe to try to leave the startup scene, but a month later, I found myself the CTO of a startup in London. The addiction continued. Eventually I found myself back in SF. I'm on my 3rd CTO role now. We're about to raise a series B.

More than I'd like to admit, I want to stop this madness and just enjoy life. Hang out with my family. Perhaps move to Denver or Austin to maintain some semblance of tech life, but get out of the madness. I've been looking at houses in Denver for over a year. And it depresses me.

I know that it can't happen. I know that I'll be working like this until my health prohibits me.

The only reason I work hard is to surround myself with people I respect.

When I find myself pushed into situations where irritating people have crept into the mix, and no one seems to be willing or able to do anything about that, I look for an exit.

Boss' nephews. Obnoxious assholes who constantly talk about getting laid. Bitchy careerist ladies who constantly demand bullshit, and seem to foment panic with every breath they can muster. Narcissistic retards dumb as a bag of hammers, but smug to the core about everything they do, which usually turns out to be sitting on their asses all day, looking up trivia about sports. Weirdos who can't seem to bathe themselves, even though they're like 40 years old?

I work hard to separate myself from these people.

Work is a good excuse around which to build your life. The excuse approaches perfection in occupations such as programming which is getting paid for what would basically be your hobby. Andas any excuseit is, as lovingly ever-favoured by your mind, easily used to avoid facing things in life, and edges in yourself. Staying busy is the opposite of having enough. It is doing versus being. When you do, you're trying to achieve something. When you be, you're liable to realise that you aren't missing anything, and that the keys to your life are found within yourself. People need both flavours but work rarely offers the latter.

I worked hard -- or, long -- because I had a shit personal life and neighbors who made it miserable to be at home. And, I was taught early and thoroughly that there was nothing I could do about such things.

Let me tell you, it is a terrible way to live.

Working hard and smartly and with fun, which I occasionally got to do, was something different and immensely satisfying.

But, if you are "working hard" because life sucks. Get your life in order. The sooner the better, not just for you, but ultimately, for your career.

Anyone who says you can't. Or that you have to "pay some sort of dues"? Fuck them.

As I overheard in the cafe, the other day -- my paraphrase may not be as snappy as the original: There's one choice where the outcome is 100% certain: Not choosing. Making no choice, taking no action, no chance.

The young-ish fellow was advising another young fellow on whether to ask a girl out.

As someone who's ended up spending his life alone -- and, is that "not by choice", or, per the above, precisely by choice. Let me tell you, there is no more important choice.

Family, friends, lovers, work and interests that matter (however, and, big or small). There is no more important choice. "Work hard" on those.

It really depends. Most times you just need the money. Sometimes you have nothing better to do. Many times you just keep doing it because you are used to doing it. A few times is your dream job and you just can't stop doing it. Work is more than economics, is not a function of money. Work is action. My father is a 73 'retired' professional and scholar, now serving as a congressman, and already thinking what to do next. Action is life and you should never stop it: work til you drop.

Another question would be: why do we keep working so hard for money when technology could already solve many of our needs?

There's several issues intertwined here. The easy ones are those market forces I experienced at the relative bottom of the pay-scale and at the smaller end of the company scale: you're asked to work harder and more hours because it makes more money/profits for your employer to get you to work as long as possible for as little as possible.

However, I think there's two more aspects I think I can contribute.

Firstly: some kind of social identity. I've worked in a fair number of fields and a fair number of jobs, so being attached to a job or thinking of "myself as a particular profession" seems quite alien. But a fair number of my colleagues saw/see themselves as possessing a particular identity, and work/professions defined that for them. We have a very powerful social indoctrination that you are your job: we have titles, little boxes for "profession" on forms, and many people have internalized the messages that "you are what you are employed as", and that you need this external direction/identity to tell you what to do (I don't want to retire, what would I do with myself?!), and that their social identity is formed through their work/networks. Its a bit of a self-fullfilling prophecy, because as we move away from community oriented networks, people's social networks do become defined by where they work. Even if you manage to get out of the ratrace, you discover that your friends are still in it, so they don't have time to spend with you and you can't identify with some of their everyday struggles if you aren't going through it also. I should also note that people who gained this identity through work took retrenchment and change the hardest psychologically, and its easy upon reflection to understand why.

The second aspect though is this: generating the impression of work. I don't know whether its base human psychology (I think there are good arguments from anthropology that it isn't) or a culture-bound phenomenon, but I believe two things: that most humans still have a fundamentally reptilian-brain/cargo-cult psychology that is pretty close to the marxian concept of a labor theory of value, and that in modern large-scale professional life, metrics able to easily tie a worker or professional's inputs to outputs/profits accurately aren't commonly available.

So there is a social/cultural aspect here: how do most people judge how much you're bringing to the workplace? If you're not working in a widget factory, most people's have a heavily weighted proxy to just look at "how busy you look".

Would any CEO, politician, or professional in our culture, ever, justify themselves in taking their salaries by saying everything was running smoothly, and their job was to sit there, like a good taoist-esque ruler, just sitting and facing the horizon and not interrupt? The very idea is absurd, even though we must admit, I think rationally, that in some situations at the very least, that may be the most reasonable course of action. No, instead we justify such by "hours work put in" because it seems to be both a good cultural proxy, and I suspect because, even if its pretty bad, at least its a good cultural value to motivate the lower-downs into being good workers.

But it is of course, on an intellectual level, obscene and ridiculous. And it results in the promotion and workplace culture that I've experienced now at a lot of firms and professional workplaces.

Fresh out of university (economics), I was under the belief that government was generally wasteful. And I worked there, and I saw that it was, and it is, and all was good :)

But I didn't know true waste until I worked for the larger private corporations. We'd hire 15 men, 10 consultants, 4 managers, and support staff to do in 2 years what I could probably do with a skilled team of 4 in my area in government in 12 months. Am i being a little bit hyperbolic, maybe...

When I worked in government, the 2-3 staff would tell you something was bullshit, bitch, take a long lunch break, but get something done...maybe not everything, but something. They weren't salespeople.

In private sector professional firms, people will just lie and say everything they do is productive and a success. Its a hustle, its a sale. They'll come in to the office and rather than eat with their families at home, they'll eat breakfast at work while still not doing anything. They'll go to conferences and say "how great we are!". They'll come up with as many jobs and tasks as they can, and the efficiency of what they do is totally irrelevant. They still play solitaire on their computers. They get tonnes of people to proofread documents n times with n meetings (before eventually switching back to the original version). They'll restructure before restructuring back. They'll fire. They'll hire. It doesn't matter, just do STUFF.

The philosophy is just spend all the money you have and get your staff to do STUFF, expand your empire as much as possible, make everyone work, be seen to work, take credit for everything good, disown everything bad.

To them, long hours wasn't/isn't inefficient or a sign of intellectual failing, its a sign of how awesome you are, and you come in early and you stay back late not because you're doing anything (indeed, amongst the honest ones, there is a haunting realisation that your job, or at least the hours you're putting into it, maybe isn't actually producing anything, or might even be creating more work...), but because its a culturally-structurally reinforcing meme.

I'm not saying that all this culture is universal amongst us, or our workplaces, or our societies. But its there, and I think its all having a pretty powerful impact on our relationship with work, labor, and status...

I also was hoping the author would discuss the developing trend of people working from home and how that relates but.. nope.

One thing that would help is if our governments, all governments, would stop spending money they don't have, and therefore stop devaluing currencies. When the Fed "buys" $4T in mortgages to relieve banks from holding any risk, where do they get all that money? They don't - they just "print" it, by clicking on a computer. And in the process, they devalue everyone's wealth.

Take a look at this chart: http://blogs.wsj.com/economics/2015/12/14/a-brief-history-of...

Yes, things are not quite as volatile since 1930, but also note that there is only inflation, whereas before, there was deflation to balance out the inflation. I know everyone says deflation is the devil. I'm not so sure about that.

I like the explanation, but I don't like the idea of telling everybody that things where different in the past. When most people were farmers they also worked more than 12 hours a day, since you need to take care of such a big place. When most people were factory workers people also worked more than 12 hours because the boss thought it would make him more money if you worked more (and with simple, mechanical work that's actually true). The kind of work changed, as well as the reason. But we always worked too much.

And there is one reason he didn't mention: When you don't work so much, you need to figure out what to do with your time. You can't watch movies all day. Nobody can do that for a long time. So you need to think hard about other reasonable things to do. And thinking is painful and scary.

Get Work Done Syndrome is truely a modern notion entirely absent from the laissez faire peasant farmers of yonderyear who tilled soil in return for a long glass of summer wine at the end and maybe a 20 minute long smoke of fine tobacco. Modern notions of work involve McDramas taking place in every western household where first world problems really are a truely despotic problem indeed. Master slave relationships engender this and it leads to a domestic tilling of the soil in the fields of suburbia, working for McJobs with a McPay. The kind of real work; that of some spiritual understanding, or mastering the body, or doing shadow work of the mind; 'Dumping all your ailments on a plate for those to ponder' is entirely absent in the west, where it is assumed that only those more credentialed shall offer answers, and none else. The East might have these problems just not as severe, and I worry about the encroachment of americanisation into the Eastern mindset and rich tradition and approach to existential crises.

OMG, guys, this is getting really strange. Half of the commenters here read the word "process" and jumped to their own conclusions, possibly true in general, but obviously wrong in the case of Erlang.

It bears repeating: Erlang processes are not OS-level processes. Erlang Virtual Machine, BEAM, runs in a single OS-level process. Erlang processes are closer to green-threads or Tasklets as known in Stackless Python. They are extremely lightweight, implicitly scheduled user-space tasks, which share no memory. Erlang schedules its processes on a pool of OS-level threads for optimal utilization of CPU cores, but this is an implementation detail. What's important is that Erlang processes are providing isolation in terms of memory used and error handling, just like OS-level processes. Conceptually both kinds of processes are very similar, but their implementations are nothing alike.

Beautiful way of putting it. Also very close to Alan Kay's vision of "object oriented"

"In computer terms, Smalltalk is a recursion on the notion of computer itself. Instead of dividing computer stuff into things each less strong than the whole like data structures, procedures, and functions which are the usual paraphernalia of programming languages each Smalltalk object is a recursion on the entire possibilities of the computer. Thus its semantics are a bit like having thousands and thousands of computer all hooked together by a very fast network." -- The Early History of Smalltalk [1]

I also personally like the following: a web package tracker can be seen as a function that returns the status of a package when given the package id as argument. It can also be seen as follows: every package has its own website.

I think the latter is vastly simpler/more powerful/scalable.

What's interesting is that both of these views can exist simultaneously, both on the implementation and on the interface side.

I get the feeling that people reading this and saying "it's just kind of like a pool of PHP FastCGI instances or Apache worker pools" etc. Do not understand that Phoenix + Elixir can serve minimal dynamic requests about 20% slower than nginx can serve static files. This is very very fast.

It also leads to better code due to being functional, lots of amazing syntactic sugar like the |> operator and the OTP can easily allow you to move processes (these basically have very little overhead) to different machines as you wish to scale. Pattern matching and guards are also incredible.

I really do not want to write anything else!

In the late 90s I implemented the same concept for a web application written in Perl. (It's still running today.) There were three tiers to it:

Tier 1: a very small master program which ran in one process. It's job was to open the listening socket and maintain a pool of connection handler processes.

Tier 2: connection handler processes, forked from the master program. When they started they would load up the web application code, then wait for connections on the listening socket or for messages from the master process. They also monitored their own health and would terminate if they thought something went wrong. (ex: this protected them from memory leaks in the socket handling code.) When an http connection came in on the socket, they would fork off a process to handle the request.

Tier 3: request handlers. These processes would handle one http request and then terminate. When they started, they had a pristine copy of the web application code (thanks to Copy-On-Write memory sharing of forked processes) so I knew that there was no old data leaked from previous requests. And since they were designed to terminate after a single request, error handling was no problem; those would terminate too. In cases where a process consumed a lot of memory it would get released to the OS when the process ended. We also had a separate watchdog process that would kill any request handler that consumed too much cpu, memory, or was running much longer than our typical response time.

This scaled up to handling hundreds of concurrent requests per (circa 2005 Solaris) server, and around six million requests per day across a web farm of 4 servers. That was back in 2010; I don't know how much the traffic has grown since then but I know the company is still running my web app. This was all very robust; before I left I had gotten the error rate down to a handful of crashed processes per year in code that was more than one release old.

BTW, while my custom http server code could handle the entire app on its own, and was used that way in development, for production we normally ran it behind an Apache server that handled static files and would reverse-proxy the page requests to the web app server. So those 6 million requests per day were for the dynamic pages, not all of the static files. That also meant that my web app didn't have to handle caching or keep-alive, which simplified the design and makes the one-request-then-die approach more viable.

You don't need to "crash the server" in response to an error from a single user - It is sufficient to just close the connection and destroy the session.

I doubt that erlang spawns millions of OS processes because that would be extremely inefficient due to CPU context switching. So in reality, all erlang is doing behind the scenes is closing the connection and destroying the session... It's not actually crashing and restarting any processes... You can easily implement this behavior with pretty much any modern server engine such as Node.js and tornado.

If the government wins any of these court battles, it's only a matter of time until one-way encryption is outlawed. It follows logically that if criminals/terrorists can't use iPhones to securely communicate, then they'll just move on to the next convenient encryption app. The government will continue to order companies to break their one-way encryption until the government realizes they're playing musical chairs and then they'll issue an executive order to ban one-way encryption outright. The precedent allowing them to do so, will be all of these initial court battles vs Apple, whatsapp, and whoever else gets defeated. In the wake of these events regular people, like you and me, will be harmed by hackers and commercial companies exploiting this new world without one-way encryption.

All computer code can be rephrased in common written (english, perhaps) language. I'm not talking about pseudocode, I mean an actual translation layer from, say, C to english phrasing that specifically describes the computer code to be written.

And at that point it's just speech. I don't mean "like speech", or "something sophisticated people should recognize as speech", or "code is speech" ... I mean, it's just plain old speech. Just very boring, long-winded (and extremely precise) descriptions of computer source code.

No one can stop me and my peers from sending meaningless garbage data to each other.

So, if it simply looks encrypted, but acctually contains randomized meaningless shit, how can anyone prevent me from bahaving in this manner, and claim that I've done harm?

I've paid for the service, and I can spam it with trash as I see fit.

I find it disturbing how the intelligence and law enforcement community seem to think there is some kind of natural right for them to snoop on people.

In case of the good old phone system, the very way that worked maked wiretapping very easy. The same was true for physical mail (one major reason why most states created and held on to the monopoly on mail for so long).

With email and IM this is - again due to the way this works - a lot more difficult. Artificially restricting encryption just so they can keep on doing things the way they're used to is a bad idea, and kind of naive, too.

Yann LeCun's comment on AlphaGo and true AI facebook.com

Preface: AlphaGo is an amazing achievement and does show an interesting advancement in the field.

Yet ... it really doesn't mean almost anything that people are predicting it to mean. Slashdot went so far as to say that "We know now that we don't need any big new breakthroughs to get to true AI".The field of ML/AI is in a fight where people want more science fiction than scientific reality. Science fiction is sexy, sells well, and doesn't require the specifics.

Some of the limitations preventing AlphaGo from being general:

+ Monte Carlo tree search (MCTS) is really effective at Go but not applicable to many other domains we care about. If your problem is in terms of {state, action} pairs and you're able to run simulations to predict outcomes, great, but otherwise, not so much. Go also has the advantage of perfect information (you know the full state of the board) and deterministic simulation (you know with certainty what the state is after action A).

+ The neural networks (NN) were bootstrapped by predicting the next moves in more matches than any individual human has ever seen, let alone played. It then played more against itself (cool!) to improve - but it didn't learn that from scratch. They're aiming to learn this step without the human database but it'll still be very different (read: inefficient) compared to the type of learning a human does.

+ The hardware requirements were stunning (280 GPUs and 1920 CPUs for the largest variant) and were an integral part to how well AlphaGo performed - yet adding hardware won't "solve" most other ML tasks. The computational power primarily helped improve MCTS which roughly equates to "more simulations gets a better solution" (though with NNs to guesstimate an end state instead of having to simulate all the way to an end state themselves)

Again, amazing, interesting, stunning, but not an indication we've reached a key AI milestone.

For a brilliant overview: http://www.milesbrundage.com/blog-posts/alphago-and-ai-progr...

John Langford also put his opinion up at: http://hunch.net/?p=3692542

(note: copied from my Facebook mini-rant inspired by Langford, LeCun, and discussions with ML colleagues in recent days)

I don't know if I'd agree that unsupervised learning is the "cake" here, to paraphrase Yann LeCun. How do we know that the human brain is an unsupervised learner? The supervisor in our brains comes in the form of the dopamine feedback loop, and exactly what kinds of things it rewards aren't totally mapped out but pleasure and novelty seem to be high on the list. That counts as a "supervisor" from a machine learning point of view. It's not necessary to anthropomorphize the supervisor into some kind of external boss figure; any kind of value function will do the trick.

I would like future competitions between AIs and humans to have a "power budget" for training and during gameplay. For example, a chess grandmaster that has played for 20 years would have spent X amount of energy training. The AI should get an equivalent budget to train with. During gameplay, the AI would get the same 20 watts [1] that a human has. This would drive the development of more efficient hardware instead of throwing power at the problem :)

It sounds reversed to me- shouldn't the "cherry" be supervised learning and the "icing" be reinforcement learning? At least insofar as reinforcement learning is closer to the "cake" of unsupervised learning, as there is less feedback required for a reinforcement learning system to work (a binary correctness signal rather than an n-dimensional label signal.)

It might also be argued that most "unsupervised learning" in animals can be broken down into a relatively simple unsupervised segment (e.g., an "am I eating nice food" partition function) and a more complicated reinforcement segment (e.g. a "what is the best next thing to do to obtain nice food?" function.) I'm sure someone like Yann LeCun is familiar with such arguments, though.

If you look at how child learns, it's huge amount of supervised learning. Parents spend lots of time in do and don't and giving specific instructions on everything from how to use toilet to how to construct a correct sentence. Lots of language development, object identification, pattern matching, comprehension, math skills, motor skills, developing logic - these activities has huge amount of supervised training that runs day after day and year after year. There is sure unsupervised elements like ability to recognize phonemes in speech, tracking objects, inference despite of occlusion, ability to stand up and walk, make meaningful sounds, identify faces, construct sequence of actions to achieve goal, avoiding safety risks from past experiences and so on. However, typical child goes through unparalleled amount of supervised learning. There was an incidence of a child who got locked up in a room for over a decade and she didn't developed most of the language, speech or social skills. It seems unsupervised learning can't be all of the cake.

Indeed, even 'purely mental' things like having an "intuition" about physics is certainly guided by one's embodied experience.

(1) Adversarial learning is unsupervised and works great.Most of language modeling is unsupervised (you predict next word, but it's not real supervision because it's self-supervision).There're many works in computer vision which are unsupervised and still give more or less reasonable performance.See f.e. http://arxiv.org/pdf/1511.05045v2.pdf for unsupervised learning in action recognition, also http://arxiv.org/pdf/1511.06434v2.pdf and http://www.arxiv-sanity.com/search?q=unsupervised

(2) ImageNet supervision gives you much information to solve other computer vision tasks. So perhaps we don't need to learn everything in unsupervised manner, we might learn most features relevant for most tasks using several supervision tasks. It is kind of cheating but very reasonable one.

Moreover,

(3) We observe now just fantastic decrease of perplexity (btw, it's all unsupervised = self-supervised). It's quite probable that in the very near future neural chat bots write reasonable stories, answer intelligibly with common sense, discuss things. All of this would be just a mere consequence of low enough perplexity. If neural net says smth inconsistent it means that it gives too much probability to some inappropriate words i.e, it's perplexity isn't optimized yet.

(4) It's quite probable that it would open a finish line for human-level AI. AI would be able to learn from textbooks, scientific articles, video lectures. Btw, http://arxiv.org/pdf/1602.03218.pdf gives a potential to synthesize IBM Watson with deep learning. May be, the finish line to human level AI has been opened already.

There's also a huge issue around problem-posing and degrees of freedom, that doesn't necessarily get better as your AI tools improve. Go has a fairly large state space, but limited potential moves per turn, well-defined decision points, limited time constraints, and only one well-defined victory condition. The complexity is minuscule compared to even something relatively well-structured like "maximize risk-adjusted return via stock trades".

It seems that AI does well when the problem and the performance metrics are well defined: chess, Go, various scheduling problems, pattern recognition, etc. At the very least we can track, quantitatively, how far off we are from a satisfactory solution, and we know we can only ever get closer.

"True", or general-purpose AI, is harder to pin down, and thus harder to define well. I'd argue that the moment we have define it formally (and thus provided the relevant performance metrics) is the moment we have reduced it to a specialized AI problem.

When you ask your AI maid to vacuum your house, you would prefer it not to plow through closet door to grab the vacuum, rip your battery out of your car and hardwire to the vacuum, and then proceed to clean your carpets. If you don't want to create a list of rules for every conceivable situation, the AI will need to have some understanding human emotions and desires.

Stop looking at the red dot. Take a step back and look around you."True" AI is here and it's been here for some time. You're communicating with it right now.

It's just that we find it so hard to comprehend it's form of "intelligence", because we're expecting true AI to be a super-smart super-rational humanoid being from sci-fi novels.

But what would a super-smart super rational being worth 1 billion minds look/feel like to one human being ? How would you communicate with it ?

Many people childishly believe that "we" have control over "it".You don't. We don't.

The more we get used to it being inside our minds, the harder it becomes to shut it down without provoking total chaos in our society. Even with the chaos, there is no one person (or group) who can shut it down.

But "we" make the machines ! Well... yes, a little bit..

Would we be able to build this advanced hardware without computers ? Doesn't this look like machines reproducing themselves with a little bit of help from "us" ?

Think about the human beings from the Internet's perspective - what are we for it ? Nodes in a graph. In brain terms - we are neurons, while "it" is the brain.

But it's not self-aware ! What does that even mean ?

Finally, consider that AlphaGo would have been impossible without the Internet and the hardware of today.

And that "true" AI that everybody expects somewhere on the horizon will also be impossible without the technology that we have today.

If so, then what we have right now is the incipient version of what we'll have tomorrow - that "true" AI won't come out of thin air, it will evolve out of what we have right now.

Just another way of saying the same thing - it's here.

Is this good or bad ? Well, that's a totally different discussion.

Accidents rose 17% that Monday? Does it mean 17% more than any other day, or just that the raw number for that Monday is 17% higher than it used to be? Because they worded it like the latter.

For all this page says, accidents were up 17% every day of the year over that decade.

All these articles seem to keep gloss over the actual issue: the switch between standard time and DST twice a year.

Both sides of the Atlantic these sort of articles crop up regularly. Move to summer time year round and so forth.

What is always forgotten is latitude, and that we forget to learn from history and experience.

In Southern England, or California I doubt it's much more than an annoying relic of olden days. But I don't think anyone has true statistics on whether it is or not. Go north and it starts to matter and accident rates go up when you don't have DST.

The UK had an experiment of staying on summer time between 1968 and 1971, introducing British Standard Time. At the end of the period, the vote was to restore the old way, by a large cross party majority.

I believe at the start of the expermient it was generally thought it would confirm the sense of getting rid of summer time permanently. Switching clocks twice a year is annoying after all.

DST is about the compromise between two reasonable scheduling systems: in one you use a 24 hour day with a clear landmark (noon, when the sun is highest in the sky). In another model you use sunrise as a natural beginning to the day.

Sunrise is a bit complicated, and in winter it compresses the afternoon more than many people would like. Also hard to build the necessary clocks. So we simplify things and make a compromise between the two systems, and we get DST.

This is insane and a complete waste of sunlight.

>If, by the way, you think the solution is to stay on DST throughout the year, I can only tell you that we tried that back in the 70s and it didnt turn out well. Sunrise here in Chicago was after 8:00 am, which put school children out on the street at bus stops before dawn in the dead of winter.

I think Daylight Saving Time is a bad idea in the same sense that (abusing) global variables is a bad idea in programming.

In programming, changing a global state in order to achieve something is almost always a bad practice because it affects everywhere and sometimes in unpredictable ways. Instead of abusing global states, we invented object-oriented programming, which I consider as a way to keep states locally (inside objects).

So if someone wants to save daylight, that should be achieved locally for example by changing school schedules.

Web compatibility is a long road, and it's crucial for us to be able to know what missing functionality is most important and the places where we need to focus on performance the most. The purpose of the package is to help us find and prioritize bugs and missing features. We want to know which sites are the most broken (and, even more importantly, which missing features are breaking those sites). From the Web developer side, we also want early feedback on use cases that may be slow today, so that the browser engine can eventually become a great experience for everyone.

A year or so ago, I've read that servo project is fairly easy to contribute to even if you have no prior rust knowledge, other than the core basics, and are willing to learn it as you go. The reasoning was that there are tons of core functionality missing, therefore there are plenty of low hanging fruits.

I was wondering, is it still true (or ever was true)?

Any plans to make the browser cache aware of cross domain resources? Basically a hash based cache, where as long as the hash is valid it can be used from a hash based caching pool. This could be integrated with SRI to reduce unnecessary network load without compromising user privacy.Will not provide complete privacy, but might reduce exposure to 3rd party CDNs.

If something like this is implemented, providing frequently used resources via a plugin, privacy aware CDN or even a custom CDN similar to https://addons.mozilla.org/en-US/firefox/addon/decentraleyes... would be possible.

 Servo project aims to achieve better parallelism, security, modularity, and performance.

I agree with the general motivation that having too much AI research in the hands of software companies who keep it proprietary harms transparency and progress. But there is already a lot of neural-network free software, so why another package? For example, these widely used packages are free software, and seemingly more featureful: http://torch.ch/, http://www.deeplearning.net/software/theano/, http://pybrain.org/, https://www.tensorflow.org/, http://leenissen.dk/fann/wp/, http://chainer.org/

The implementations look odd. A network consists of a collection of neurons, which are implemented individually as structs. The forward pass through the network is a series of nested loops, and the gradient descent implementation doesn't use backpropagation - it uses finite differences to approximate derivatives, which is known to be inefficient. Given the overall design of the library, it isn't really clear what you would use it for in practice.

I hope that future versions take inspiration from other open source machine learning libraries, which show how to use linear algebra and backpropagation and are much more effective.

- It's nice that GNU is taking on such a project

- FANN seems like a pretty good alternative

- The value of the software at the big "monopolies" lies within the data, not necessarily the software

- This needs to be in some publicly accessible repo. Downloading a zip file and submitting patches? I thought we, as a society, were over that way of building OSS.

Funny.. The majority of AI research is currently using open source libraries (Theano, Lasagne, Torch, Keras, Scikit-Learn, Nolearn, etc. etc. etc.)

Now Google does have access to a whole lot of data that the rest of the world doesn't. and FB, Google, and etc. have more than a bit of a hardware advantage... for now, at least. Distribute a shared system over a P2P infrastructure, and you can change that. Perhaps rather significantly.

This is something that I have wanted to exist for a long time, but is a pretty massive undertaking because there are so many small niche podcasts.

The podcasts I spot checked all looked fairly accurate, although you do need to be careful with common names. Jordan Morris [1] is the name of a podcaster/comedian, a soccer player, and a singer. All of their profiles are combined into one. In order to separate those out you would need to do some analysis on the genre of the podcasts. The podcasts that talk about sports are probably talking about the soccer player, etc. It is also tough to rely on common lookup tools like Google because the Jordan Morris that is a podcaster is probably the least famous of the three but is clearly the most relevant for your site.

Awesome product. I love that podcasts are getting more attention, with companies creating discovery platforms like http://producthunt.com/podcasts.

One suggestion - would be really nice to have categories for podcasts. Much like movies, it is difficult for niche/indie movies to compete with the super well funded hollywood productions. For example, we produce a software podcast (http://softwareengineeringdaily.com) and it would be a huge benefit to be able to search for Tech specific shows and see what's relevant to you.

Keep up the good work!

Overcast[1] has an index. At least for the incredibly small subset of podcasts I looked at, Overcast is a more complete index.

Podcat does not seem to get the names of podcasters correct. For example, searching for Marco Arment links to only some episodes of 'Build and Analyze', which is Arment's old podcast where he appeared in 100% of episodes.

Podcat appears to index names if the given name is name-checked in a podcast's episode text. That's going to be a spam target.

Potentially Podcat could be a great thing. Interesting work.

Please keep it up and continuing to find a way to make it more complete. Right now I can find appearances by Daniel Negreanu by searching in iTunes, but not through Podcat.

Another possible feature: strip out the repetitive portions of episode descriptions on the results page when the displayed text is always the same for all the results on the page.

This looks cool, very fast search and I like the idea of referencing names (presumably through name-checking of episode summaries?). I worked on a side project a few months ago[1] as I just wanted my own personal webplayer. It's OK, but has the limitation that it only works with podcasts that have discoverable RSS feeds; many are behind the walled gardens of iTunes or Soundcloud or other proprietary platforms unfortunately. As it's really to scratch an itch for my own needs it doesn't do ratings/comments/recommendations which would be on my todo list for a more complete app. Are you planning on adding these features in the near future?

Funny automation fail:

The tech podcasts I listen to frequently end with recommendations.

One of the recommendations in the latest JavaScript Jabber is for a Taylor Swift album.

Podcat attributes the entire episode to Taylor Swift

Podcat Episode Details: https://www.podcat.com/podcasts/D13bdo-javascript-jabber/epi...

Request:

Since most of my podcasts are technical (as I assume many other HN readers' podcasts are) many of them also have video. Sometimes only specific episodes have a video component (e.g. Lately in JavaScript), and sometimes every episode has a video component (e.g. JavaScript Air).

All of the ones I listen to that have video versions also provide an audio-only version, but the host or guests occasionally still refer to something on the screen.

So, it would be nice to be able to filter on episodes that do or don't have a video version.

the "top 250" would be interesting and for me personally, I'm not sure how much faith I'd put into it: I'm quite finicky when it comes to podcasts. I have a couple of podcasts that I listen to religiously, but I also have some podcasts that I subscribe to, but would only download depending on the guest for that episode, and then there's some podcasts that are right up my alley, interest wise, but something as simple as one of the person's voices/accent is so off-putting that I disregard it completely. With movies, it's easy to say "that movie isn't for me, but I can understand the praise it's receiving", but I don't think podcasts really work that way

Which cryptographers and cryptography experts think, in 2016, that a crypto system could be created that is, baring bugs, completely secure right up until the point where you don't want it to be? He showed clips of legislators asking for magic crypto unicorns (10m). Is this some kind of 4 out of 5 cryptographers think it's an "impossibility", and do we really think that that remaining one is actually an expert?

Or is this just an attempt at "fair and balanced" reporting, implying that, while they couldn't find any "experts" to take the opposite side, there must be some out there. John Oliver doesn't usually do that though.

Would it be possible to build devices that could be unlocked a fixed number of times across all units (say 1,000 times). Devices could be heavily hardware encrypted, but unlockable with an encryption key, a portion of which comes from a publicly monitored blockchain/distributed ledger, that when used reduces the number of future uses.

This way, the government could be granted access for extreme cases, but without the potential for abuse or mass surveillance. Once there were 1,000 check-ins, not more keys could be generated.

Thoughts?
