People can't seem to summarize his argument without getting much of it grossly wrong, because his manifesto was a haphazard collection of good points, bad points, good arguments, lousy arguments, misrepresentations of others' views, and unstated implications. A perfect recipe for people to argue past each other about it.

It's worth remembering that one of his conclusions was to end or replace gender-based diversity programs at Google. Given that, it's easy to understand why people would be upset. If gender-based diversity programs are responsible for qualified women getting jobs that they otherwise wouldn't have gotten due to bias, then the lack of that program means those women wouldn't have gotten those jobs.

Disney acquires own streaming facilities, will pull Netflix content thewaltdisneycompany.com

Maybe when I am 60, 70 or 80 the film industry will get their shi* together and finally agree on a solution that has long been found in the music business.

For a truly complete platform, I would FOR SURE pay more than the 10$ a month for Netflix. 20, maybe 30! But then I want it ALL. All films they have in storage.

I mean, it is 2017 and there are a lot of films I can't find on Netflix, Amazon Prime or, when I am in spending mood, on Apple TV. Why? I mean how silly would you want to be as studios? There is no big DVD business anymore, BlueRay never totally took off. People have a net connection and multiple streaming devices at home, thats it. Thats the big asset they could build on! Instead they let their libraries die the death of the unseen film.

Still, many keep shuffeling around harddrives with terabytes of pirated films. And why shouldn't they, as long as there is no substantial offer?

So I decided for me (and the cloud guy I am), that with my 3 services I have, I am ok. If a film is not there, I don't care. I surely won't order a DVD of some old film somewhere and I surely will not subscribe to another service. If Disneys pulls their films from Netflix: thanks Netflix for their growing self produced content that often has a quality not seen before.

If every studio thinks I'm going to pay them $10+ a month to stream their content, they are going to be very mistaken.

I can't imagine that a lot of people want to spend the collective hundreds of dollars to sign up for all the streaming services. It's almost asking to drive people to torrents.

Now, if Disney does something like $30/year or something really affordable - sure. I might do that on a whim. I guess it's all about volume vs. price.

Netflix, however, I'll keep paying for gladly because of the library size. For the streaming price, it is well worth the value.

The records I clicked on have this notice

Digitized from a shellac record, at 78 revolutions per minute. Four stylii were used to transfer this record. They are 3.8mm truncated conical, 2.3mm truncated conical, 2.8mm truncated conical, 3.3mm truncated conical. These were recorded flat and then also equalized with NAB.

The preferred version suggested by an audio engineer at George Blood, L.P. is the equalized version recorded with the 2.3mm truncated conical stylus, and has been copied to have the more friendly filename.

I'm trying to guess but can't imagine what the reasoning for this is. I've tried A/B/C/D testing a few tracks on some crappy speakers and can't discern any difference.

While it's certainly admirable to try and digitize it as thoroughly as possible, I just can't see how a difference of 0.5mm in the stylus width is worth increasing your work load 4x times over (having to record each record 4 times rather than just once).

Some very very good stuff in here. I've gotten pretty into 20s thru 50s music over the past couple of years. I usually buy compilations on LP, though, so it's a treat to find these straight off the 78s. A big portion of the stuff never even makes it to digital.

Just at a glance, I'm seeing The Light Crust Doughboys[1], basically a string band supergroup. Multiple members would go on to found famous western swing bands (Bob Wills, Milton Brown). Very proto-rock-and-roll -- listen to that electric guitar -- Elvis would cover some Western Swing numbers[2] in his early days[3].

Also seeing some older stuff, including a few recordings by the (arguable) best banjo player of all time, Vess L. Ossman[4] (from 1907). Pretty cool to listen to these march numbers and then hear them evolve into jazz/ragtime only a couple years later[5] (this is a recording by Fred Van Eps, the second best banjo player of all time, from 1914).

EDITS: seeing some other personal favorites:

Hank Penny, a favorite western swing singer of mine[6]. He usually does it hot/upbeat/fun.

Blind Blake, a guitarist who could play the fretboard like a ragtime piano[7]!

Oh, and here's the WWII-era Bob Wills I was waiting for[8]. Got that classic Leon McAuliffe pedal steel playing. No Tommy Duncan vocals, unfortunately.

Neat! An old solo Art Tatum[9]! Widely considered the best pianist of all time... And another, a whole album[10]!

Really classic early electric guitar playing on a jump blues number by T-Bone Walker[11]. I actually believe he's one of the first to use the electric guitar in blues.

Great steel guitar playing on this Gene Autry cowboy number[12].

Looks like there's a lot of Django for all you gypsy jazz fans[13]. Never heard this take on Avalon before, I dig it.

Lot more to dig through and lot of obscure stuff I'd like to give a shot, but I'm out of time for now...

Internet Draft: Let 'localhost' be localhost ietf.org
587 points by beliu  1 day ago   162 comments top 23
user5994461 1 day ago 8 replies      

 First, the lack of confidence that "localhost" actually resolves to the loopback interface encourages application developers to hard-code IP addresses like "" in order to obtain certainty regarding routing. This causes problems in the transition from IPv4 to IPv6 (see problem 8 in [draft-ietf-sunset4-gapanalysis]).
That does remind me of the times I was dealing with weird connection issues in some critical services.

It turned to be related to the use of "localhost" in the configuration. It resolves to ipv6 on some systems and that breaks everything because the target app is only listening to the ipv4 address.

Went as far as removing all references to localhost and added lint errors in the configuration system so that noone could ever be able to give localhost as a setting in anything.

On the one hand, this isn't exactly a new idea and in the real world has been happening for years now.

* dnscache from djbdns has handled "localhost." queries internally all along, since 1999. It maps "localhost." to and bgack again. Various people, including me, have since added code to do the same thing with the mappings between "localhost." and ::1. (http://jdebp.eu./Softwares/djbwares/guide/dnscache.html) I implemented implicit localhost support in my proxy DNS servers for OS/2, as well.

* It is conventional good practice to have a db.127.0.0 and a master.localhost "zone" file on BIND that do this. This is in Chapter 4 of the book by Albitz and Liu, for example.

* Unbound has built-in "local zone" defaults mapping between "localhost." and both and ::1.

On the other hand, this proposal explicitly rules out all of the aforementioned existing practice, by demanding that both proxy and content DNS servers instead return "no such domain" answers for the domain name "localhost.". That seems like a fairly pointless deviation from what is fast approaching two decades of existing practice, for which no rationale is given and none is apparent.

At least on the OS I use, which is more IPv6 ready than most, /etc/hosts solves this "uncertainty" problem.

I have found that failing to include a localhost entry in the HOSTS file can lead to some strange behavior.

If there are "computers" out there that have no /etc/hosts or deny the computer's owner access to it, then maybe it might be time for an Internet Draft from Joe User.

There should always be a mechanism for the user to override the internet DNS. And applications should continue to respect it.

Also very important to point out; this same standardisation is missing on the TLD level.

Both for safeguarding internal use, and making a global TLD reserved on the global DNS zones.You'll find organisations using in production .local .dev (Taken by Google on 2014-11-20, followed by .app in 2015) *.zone (Taken by a LLC on 2014-01-09 ) as internal domains, with potential conflicts with the Internet's DNS resolution.

More importantly .dev [1] and .zone [2] are now valid TLDs, so watch out people!

One time I was debugging a problem for a user of our desktop software (I work on https://expo.io) by sharing his screen and taking over his computer.

I have no idea how anything worked on his machine.

Took a while to track that was down. Was both bewildering and sort of satisfying to figure it out in the end.

Right now, section 3 of this draft would prohibit all SRV queries for localhost, which may hinder development and deployment of a SRV based application. That's an immediate problem.

But not only are there existing applications to which it is immediately applicable - it is a design error in HTTP that plain address records are used for resolution. One day this will be corrected, in which case measures like this should continue to apply.

If you're looking for The Single Greatest Predictor of Future Stock Market Returns[1], here it is: http://www.philosophicaleconomics.com/2013/12/the-single-gre...

This is a long read, but it's worth it. The metric can be calculated in FRED[2], and as a predictor of future returns, it outperforms all of the most common stock market valuation metrics, including cyclically-adjusted price-earnings (CAPE) ratio[3]. (Basically, the average investor portfolio allocation to equities versus bonds and cash is inversely correlated with future returns over the long-term. This works better than pure valuation models because it accounts for supply and demand dynamics.)

I've never seen market valuation expressed as market cap as % of GDP. I'm not an economist, so I'll leave the detailed arguments to them. But it would be at least useful to explain why you think this is a meaningful metric as compared to those typically used to measure market valuation (e.g. P/E ratios etc.).

Your graph also ties your valuation metric to the 2000 peak and the 2008 peak. However, there were crashes in 1990 and 1987 as well. Should readers conclude that the 1987 peak level was also too high, and that therefore the last ~30 years have also been too high as well? (Abstaining from investing in the stock market at levels above the 1987 crash would have resulted in the loss of tremendous opportunity for wealth creation.)

There are a lot of opinions implicitly expressed in this site; it would be good to try to make those explicit.

For market overvaluation, it says: 9.1 / 10 "DEFCON 4"

DEFCON 5 is peacetime, DEFCON 1 is imminent nuclear war. For example, during the Cuban Missile Crisis, the US reached DEFCON 2. Should this say DEFCON 2 instead? Or is "above" normal readiness the intended meaning?

The metric used to calculate market overvaluation is interesting but it has little value for predicting a stock market crash.Let's take he last 3 major US crashes:

1987: this crash was caused by automated trading systems which could run wild in the absence of any prevention regulations such as circuit breakers

2000: the collapse of the dotcom bubble

2008: start of the financial crisis caused mainly by opaque credit default swaps and packaged subprime loans

Of those 3, only the dotcom bubble seems to be a bit related to the market overvaluation metric. And even right before the dotcom bubble crash there were plenty of economic guru's who argued that classic overvaluation metrics were not valid anymore because we were now in a 'new economy'.

The other two crashes were caused by black swans; occurrences that nobody was aware of and that were only understood afterwards. Most likely the next crash will be a black swan as well.

Good idea for a website, should be able to get you some nice revenue from intermittent visits. You probably want to focus on financial services for your ads.

I'm not going to say anything about your numbers and your models other than, without the ability to see how they looked at previous crashes, it's hard to see if the site is useful. To the innumerate masses and emotional investors the flickering numbers are persuasive enough. So they really don't matter.

On the bad side, your UX is god-awful. Use an oldish, slightly crappy monitor to look at it and you will discover that your background is indistinguishable from the foreground. The top bar of the box completely disappears, too. Also, a row of buttons is NOT a good tabbed interface--there is no indication that clicking on "Market Volatility" is going to reload all the content below the row of buttons. Maybe make actual tabs, at least make that stuff a distinct box.

This could be a nice little side product to make you some extra money. Get some GA on there, and slowly add features. I think a bit of interactivity and the ability to customize the predictive models through some drag and drop could actually make the page sticky and get people coming back.

How is the heat matrix diagram calculated? It seems to be wrong. Public Debt has a 3.7/10, while it looks like its around 8.5 in the heat diagram.

Looking at the individual ratings:- Household Debt: 5.5 / 10- Market Overvaluation: 9.1/10- Market Volatility: 0.3/10- Public Debt: 3.7/10--> SUM = 18.6/40 or 46.5%

Also I noted: Drawing a linear trend line through the "Market Overvaluation" diagram, does make it look a lot better though. One could argue that people get used to certain levels, hence a growing trend over time.

Taking only these factors into account, it does not look like the market is gonna crash soon. In my opinion it's likely going to be caused by another factor not listed here ;)

Correct answer, of course, is no one knows, because the future is opaque and unpredictable. And indeed you have some very smart professionals going to cash or directly betting on a 5-10% correction in the S&P500. And a set of equally smart fund managers calling for a 2600 target by mid-2018.

What we can say with some certainty, based on options activity, is that if a single day 3-4% drop in the S&P500 occurs it can trigger a massive unwind in short volatility positions:


And with several political risk factors on the near term horizon, including the possibility of a government shutdown in late September due to the failure of Congress to extend the debt ceiling (yes, they are arguing over who is going to pay to fund the border wall with Mexico). It certainly should surprise no one if a coming tomorrow could be very different than the extraordinarily low-volatility landscape we face today.

I was (sort of) there when the 2000 tech crash happened and was in the thick of it when the 2008 crash happened.

This thread and a few offline conversations made me reexamine what I believe about the stock market and the nature of the 2000 and 2008 collapses. Of course, I'm not an econ nor do I have data to back up anything I'm saying.

All manias, from tulips to tech IPOs to housing bubbles are born when the common person joins the frenzy. On the flip side, the mania collapses when the common person walks away or never shows up the party. For the tech IPO frenzy of 2000, the common person never even showed up to use all those exotic new ideas which were getting funded and going public. During the housing bubble, the common person bought and sold houses which setup the flywheel. Eventually, the common person walked away from the asset in question bringing down the entire charade.

Today, the market is soaring. People are starting to wonder when gravity will reassert itself but in my view, this time the difference is that the common person cannot walk away. Unless adblocking and disdain for social media become extremely mainstream, the common person is so busy amusing themselves to death online that they are not going to leave the tech mania. Companies like FB and Google have made the web sticky.

Does this mean the stock market will rise indefinitely? I don't know. I do know that once there is a captive market comprising everyone online, no company is going to stop advertising or figuring out ways to reach buyers online.

We are in a new age where you just can't get away from the web. We are the product but we also have no way of exiting the dragnet.

This is sooo cool! Great job.

One thing that might be helpful is to have a separate (informational) page that indicates what the diamond looked like at other period of economic failure--in fact, what it looked like leading up to the period of failure/crash would be really interesting.

I'm curious: How quickly can some of these variables changes? For example, it seems the VIX is at it's low end--how quickly can it spike to say, 30? How fast can the other vars change?

Economist here. You should really keep in mind that the same GDP must go both towards paying off the national debt and paying off household debt. Also you should track commodities (at the very least, the ratio between put & call options).

Your volatility section seems to be a very poor indicator of a future crash in the manner you are using it. Volatility is not a predictor, but instead a descriptor. An analogy I think is the weather stick - Is this stick wet? Then it is raining. It is a very poor item to use in your context.

Further, sustained periods of low volatility often are sometimes indicators of complacency among investors and indicators of higher chances of bubbles. Sustained periods of low volatility are at times indicative of higher future risk of a market crash, not a low predictor. I think you need to re-evaluate how you use volatility.

Normalizing household debt against the GDP makes the assumption that we are comparing the debt with the ability to pay for it.

But according to graphs like this, even though the GDP has been rising, median households have not been getting a corresponding increase in income: https://en.wikipedia.org/wiki/Household_income_in_the_United...

So the income we are adjusting against is not necessarily going to the people that are in debt!

So VIX doesn't give an indication of much. The VIX formula has changed so many times, and the human behavior around the assets that VIX tracks has changed to reflect those changes and the new products those changes are based on.

Different people gamble in weekly S&P500 options than gambled in monthly S&P500 options. Different people gamble in the 5 consequetive week at any given moment weekly options, than gambled in the single week at a time weekly options.

The options market itself has had ebbs and flow in interest.

And the self fulfilling prophecy of keeping the market propped up when everyone buys PUT options expecting it to crash has disillusioned a lot of people from participating at all. People know what the central banks are up to, why pretend to have confidence in any of it. The Swiss bank is printing money to buy US stocks for free. Everyone's creating money through new bond issuances to buy things for free.

This all contributes to a lower VIX.

American companies sell products & services outside of the United States. Comparing American GDP with the aggregate value of the US stock-market is deeply misleading, especially given a historical comparison: foreign markets such as China have gained in relative importance over timeframe under consideration.

When looking at debt, one should not just observe the nominal amount, but also the interest rates, which have never been lower. Large companies can tap public debt markets and borrow billions at 1.5% over a timeframe of ten years. Risk is thus lower than the website suggests (at lower interest rates, a company can carry more debt). Additionally, returns to equity will be higher (the I in EBIT is smaller, so profits are bigger).

As the site makes clear, nobody really ever knows if the market is going to crash. On the market valuation side they claim the current market is overvalued. But overvalued is a relative term... As you have to value versus something, and that something is usually something historical.

The way I see it though is the markets are a big voting machine.. and they're making predictions about the future and incorporating future expectations. With the current US administration still pondering over tax plans and infrastructure stimulus packages that are promised, market may be underpriced???

The volatility index, or VIX, has become a popular measurement to reference in the context of predicting the market over the past couple years.

The problem is that it does not seem to have any real predictive power and I have yet to see any shred of evidence that the VIX has been shown to have predictive power over the future value of the stock market.

It is calculated from past price variance and is used in calculating the theoretical price of options, but that is it.

Does anyone have any evidence the VIX has value?

I think you could estimate much more accurately with the prices of deeply out-of-the-money put options. Those are effectively a betting market on whether stocks will crash or not. We should expect option prices to take into account every major factor (not just these four), because if they didn't, people would get rich by trading on the "missing" info until prices corrected themselves.

One could argue that the volatility scale should be the other way round; that the diamond should be showing extreme values on everything other than household debt, which is middling.

The market is normally calm on the way up, which is why you might think its current upward movement will soon be interrupted by a volatile down-move.

The market is a chaotic system, with severe non-linear responses. As such, it can remain stable much longer than people think, and crash much harder than anyone expects.

I love the idea, the simple design, and the humble tone of the byline ("no one knows for sure, but there are indicators that can help us guess. We can chart these indicators to give us the illusion of foresight.").

However, I have two suggestions. First, the numeric rankings (such as "5.5 / 10") need context: why not say something like "10 is the highest value reached in the historical record"?

Second, the explanations you give for chosing these indicators need a bit of work, as evidenced by some of the comments and questions on this thread. Most lay readers won't understand why the ratio of total stock market capitalization to annual GDP is important.

Companies commissioning stories has gone on for a long time.

For example, the Isaac Asimov story "My Son, The Physicist" was commissioned by an electronics company to run in an ad in "Scientific American".

Another Asimov example. "Think", IBM's in-house magazine, commissioned Asimov to write a story based on this quote from J. B. Priestly:

> Between midnight and dawn, when sleep will not come and all the old wounds begin to ache, I often have a nightmare vision of a future world in which there are billions of people, all numbered and registered, with not a gleam of genius anywhere, not an original mind, a rich personality, on the whole packed globe

Asimov write the story "2430 A.D." about a world where Priestly's nightmare had come true. (The title comes from his estimate of when human population at its current growth rate would reach the point where the Earth had so many people that there were no resources left for non-human animals).

The funny thing about this story is that "Think" rejected it, because they wanted a story that refuted the quotation. So Asimov wrote another story, "The Greatest Asset", that refuted Priestly, and sent that to "Think".

"Think" then decided they liked the first story better and ran "2430 A.D."!

I'm pretty sure that there was at least one other similar case with Asimov.

"Software engineering researchers have a tendency to be optimistic about the future. Though useful, optimism bias bolsters unrealistic expectations towards desirable outcomes. We argue that explicitly framing software engineering research through pessimistic futures, or dystopias, will mitigate optimism bias and engender more diverse and thought-provoking research directions. We demonstrate through three pop culture dystopias, Battlestar Galactica, Fallout 3, and Children of Men, how reflecting on dystopian scenarios provides research opportunities as well as implications, such as making research accessible to non-experts, that are relevant to our present."

Interesting they mention and get quotes from the author of the Three Body Problem series. I just finished reading that series, and the whole time I had the feeling that it was written more to convince people of something than to actually entertain the reader.

The ideas in the books were pretty amazing, unique, and imaginative; but the story and writing itself was quite sub-par.

edit: I listened (audio books) to the English versions. I thought the translation was excellent. I don't want to spoil anything, but the author has a very dark vision of mankind and kept having his characters ostracized to the extreme which got old pretty quick. I didn't feel like the books were missing anything descriptive from lack of translation.

This is actually part of the plot of the movie (Three Days of the Condor) and book (Six days of the Condor). The protagonist works at a CIA site where they read basically everything released and break down the plots to see if it has any strategic value and/or state secrets.

If I had to guess, this still goes on at the state level, but this article is about making this sort of data (minus the state secrets awareness) available to the corporations able to afford it.

I'd also say that I think this might be an amusing reversal of the old mantra: Ideas have no intrinsic value. This business is pretty much about the expression of ideas. Maybe they have value because they are writing them down and marketing them.

Rest and vest: engineers who get paid and barely work businessinsider.com

There seems to be conflation in this article between two very different groups.

Group A is folks who are acquired and have outsized grants that say vest over N years (N between 2 and 4). It turns out the acquisition was probably a mistake, but the acquiring company made it (and won't own up to it). That's what's described in the Facebook and Microsoft examples. This is the classic "rest and vest" scenario (Note: an acquisition is not required, just any outsized grant).

Group B is "just" engineers at Google, Facebook, etc. getting paid really well for not doing much, while hanging out with the lavish perks. I've never heard of anyone refer to this as "rest and vest". In particular, I found this quote disturbing:

> There are a lot 'coasters' who reached a certain level and don't want to work any harder. They just do a 9-5 job, wont work to get promoted, dont want to get promoted.

At Google (and elsewhere), it's considered fine to reach a senior / terminal level and stay there. Is a VP or Director of Engineering lazy if they never move up? Of course not. The same is true of individual contributors.

Finally, the numbers mentioned for compensation are normal for very senior engineers at Google (and again, Facebook, Microsoft, etc.). This isn't "rest and vest", it's just business as usual. I don't particularly agree with the folks who spend their days in classes, taking long lunches, etc. but if they get their work done, what do I care?

It's not just SV that has this phenomenon. I worked at the NASA Jet Propulsion Lab from 1988 to 2000. I had risen to the rank of Senior Member of the Technical Staff, the second-highest rung on the technical career ladder. Beyond that there is the rank of Principal, which is very hard to attain. It's essentially the equivalent of getting tenure. It requires peer review. Most engineers never attain it, and I was not optimistic that I ever would. So in 2000 I decided my JPL career had peaked, and so I quit to go work for an obscure little Silicon Valley startup in Mountain View. ;-)

To my surprise, when I announced my departure, a bunch of people suddenly came out of the woodwork to tell me that they really didn't want me to go, including a number of very senior managers. So I used that as leverage to negotiate a deal for myself: I would come back after a year on the condition that I be promoted to Principal. Which is what happened.

The problem was that my promotion did not in any way coincide with JPL's strategic needs for my skills. One of the reasons I had left was because I had been on the losing side of huge political fight (http://www.flownet.com/gat/jpl-lisp.html) and when I returned I couldn't find a project that was willing to take me on. But they couldn't fire me because I was a Principal. So I basically spent the next three years getting paid for doing nothing, and getting pretty depressed about it. It's actually not fun to feel like a parasite, at least it wasn't for me.

Can confirm.

But it's not a nefarious thing and the people aren't slackers: 90% of the people who end up in this position are ass-kickers who strive to have impact and get bored: most feel bad about slacking but their bodies and minds simply need a rest. They created BILLIONS in value and even providing tech support, they "pay for themselves" many times over -- that's why companies like Google keep them around.

Subtly: the kind of people who end up resting-and-vesting are precisely the kind of hyper-ambitious people who develop unique knowledge and skills.

This article is very misleading. It's not uncommon for engineers who've been instrumental to a key product or development to be given a light duty afterwards. This is primarily because these folks bust their ass and quite literally are exhausted once their project ships. The time with light duty is meant to retain this key talent and give them back some work-life balance. Also if your thing lands and it's big enough you usually get promoted and they want you to focus on soft skill development, literally making friends, so you can go on to do something bigger. My last half, my manager told me that all he wanted me to do this half was make friends. This is because he was giving me space to find the next big thing. When you shift from task oriented work to bigger picture stuff, you can't just start building stuff thinking people will use it. You have to spend time talking to people about what problems they have and see if you can come up with a way to solve them. It's really not unlike a startup in that regard.

There's also the old joke of the mechanic that comes to fix the machine by knowing where to tap with a hammer. So having people around who know where to tap is key. They are well worth what they are getting because sites like Google, Facebook, Amazon, etc... can't go down and if they do millions of dollars are burning for each minute those sites are down.

I attended Caltech in the era that Feynman was a professor there. I heard he was paid XXX a year. I opined that was ridiculous, who could possibly be worth that much?

An upperclassman laughed and told me that Feynman was worth that much to the university even if he did nothing. Attaching his name to the university brought in donations, grants, and top talent.

Of course, Feynman being Feynman, worked like hell anyway.

Ok, thanks for sharing this. I made this observation for the last 3 years myself, not as an employee even, but as a contractor. I had three positions at two companies, all paying quite high (150k$/year). I changed the positions because the workload was so low that I had an hour of work a day, then pretending I was doing work for the rest of the day which I can't stand for more than a few months. Now I changed again in the hopes of having real work to do, comes out that they contracted me only for "if there will be work in a few months". Interviewing several people on what I can do for them: essentially nothing. "Maybe you could google if using docker would make sense". On the one hand this kind of "work" feeds my family and hives me lots of freedom, but on the other hand it leads to nothing. And I am usually not the only one who has no idea why they are going to work.

And they wonder why house prices in the bay area are so high. :-(

I started work at Sun Microsystems on the Monday after they had IPO'ed (the previous Friday). It was about a year later when all of the various restrictions on personal stock sales had been lifted that I clued in that some people just didn't care any more about work and it was quietly explained to my shocked ears that these people were now multi-millionaires and working was no longer 'for a living' it was 'for the fun of it.' Or not. And I asked why they didn't just leave and the answer was simple, because it gave them something to do and their friends all worked here. Further many of them had been given additional "refresher" options and the more the stock went up the more they were worth thousands a month in additional value down the road.

I was fascinated to see how the different people responded to that new found wealth and the options it brought with it. For the good ones, it empowers a sort of fearlessness to do the right thing even if you boss doesn't think its the right thing. Or to advocate for an important point that might be politically inconvenient for the company. For some it affected their opinion of everyone else as if they were somehow so much "more" than folks who hadn't been there pre-IPO.

Fortunately most of the latter types left fairly quickly.

I could see how it could easily be the 'best' management choice to have someone like that not putting in too much face time at work. Bad managers control their reports by threatening to fire them, if you can't control them they are a threat to the bad manager, better to keep them far away from anything that could set them off.

That said, if you find yourself in this place the absolute worse thing you can do is to do nothing. Get healthy, learn something, use that 'free' time productively. It isn't like you can get it back later.

>Medina said he experienced the high-pay, no-work situation early in his career when he was a software engineer in grad school. He finished his project months early, and warned his company he would be leaving after graduation.

>They kept him on for the remaining months to train others on his software but didn't want him to start a new coding project. His job during those months involved hanging out at the office writing a little documentation and being available to answer questions, he recalls.

This isn't a good example. The company budgeted X dollars over Y months for a total comp package of Z for an engineer they knew had a discrete timeline, and the engineer finished in Y-3 months. What should the company do, fire the engineer and save delta-Z? The company got what it wanted and more by having him stick around and answer questions and do documentation work for 8-10 hours a week of "free" labor.

I did the work-from-home (wfh) thing for about 5 years across two different jobs. The first job was the worst kind of wfh situation because there simply weren't any boundaries between work and home and day work bled into night into weekends.

The second was the other worst kind, paid very well to do almost nothing, and again day nothing bled into night nothing into weekend nothing. I tried to use it to study things or learn other topics, but every once in a while I'd be needed for a few days, go and put a fire out and be back home doing not much at all. The reason for the situation was a disastrous corporate management. However, the situation was so great in theory (get paid top-10 metro senior pay to do nothing at all) that I actually had a hard time changing jobs because I kept telling myself I actually enjoyed screwing around.

Given a binary choice of one or the other I'd actually choose the second job again, but I'd structure my days very differently and try to be much more productive. The good news is that life isn't binary, and I'm in a place now where I work most days in an office, but can wfh when I need to, and rigorously control my schedule so work and home-life don't intersect. I took a pay cut, but I love this current work much more than either of those two jobs (and my wife is much happier as well) -- lessons learned I guess.

The article lumps few different scenarios under the sensationalist "look, ppl are making shit ton of $$$ and are barely working!!!" umbrella.

None of the scenarios are unique to SV or even IT world in general, the only "shock factor" is the compensation figures.

But again, most of the scenarios are pretty typical to corporate environments. Unless you're on some "kick ass all-star" team, once you start growing you can cruise if you choose to.

What struck me as odd is the "Just dont talk about it and everyone will assume you're on someone elses team" bit. Can't really picture an environment where a person doesn't show up the next day and everyone just "assumes" they are on a different team now...

This is probably why Apple, a hardware company, has operating margins that are higher than Google and Microsoft (even though their gross margins are almost half of Google's and Microsoft's).

The only person I can think of that might have this arrangement at Apple is Scott Forstall. I think that's why he's been radio silent until very recently (or he could just be very loyal to Apple). Maybe Katie Cotton when they changed their approach to PR from wartime to peacetime, but that could just be a regular retirement.

I mostly don't understand how Google and Microsoft employ so many people, or what they even do.

I know the rest and vest type. It can be demoralizing for others to know that some in the company aren't pulling their weight, because they got lucky in the past with stock offers.

It's one of the many reasons I like Netflix. We allow engineers to be paid almost entirely in cash. No one is resting and vesting that I know of -- not only because we wouldn't tolerate unmotivated people -- but because there's no vesting schedule that I know of. AFAIK, you can leave any time with everything. If you want to leave, then leave. We'd rather hold onto people that actually want to stay and get stuff done, and be self motivated.

One of the interesting trends of the past 10 years is the degree to which "big tech" has replaced "big finance" as the place for the elite to go to collect huge paychecks for relatively "nice" white collar work.

It makes total sense for top SV engineers to get paid well, IMO. But I am afraid working for these big tech firms is starting to have that feeling of "elite pedigree" that pervades complacent industries, like finance.

In 2002-2006, one could have written a similar article, but about top staff at Goldman, Morgan, UBS, etc. There were plenty of $300k-$500k salaries being paid for maintenance work for profitable business lines.

Options and RSUs are an interesting twist in Silicon Valley. To compete with the stock option packages given out by startups to early employees, Google and Facebook grant RSUs (and similar) instead. In Wall Street, the "golden handcuffs" used to be a near-guarantee of a year-on-year raise, an end-of-year cash bonus, and a track toward promotions that had built-in pay increases. No one wanted to throw away their time invested in a single firm. SV firms are different in that turnover is high, so vesting acts to counteract that. They have such fast-growing stock values, the stock grants can also be used in lieu of bonuses. Plus, to management, it really is "funny money" that does not actually increase operating expense.

Anyway, though the mechanics are different, it seems the net result is the same. "Golden handcuffs" are as real in tech as they are in finance.

The saddest reflection I have on reading this article is on how capitalism seems to value different professions wrongly.

These salaries are bigger than top specialist physician salaries. And physicians need 12-17 years of post-undergrad training, as well as often requiring $200k of medical school student loan debt.

It just seems like if Google and Facebook can afford to pay this price for engineers (who add leveraged value via their software contributions), capitalism should figure out how to pay doctors more, as well.

And go down the list of other "non-BS, but comparatively underpaid" professions like teachers, firefighters, etc. They could all use a compensation upgrade.

But what is the exact mechanism that is making it so finance and tech are among the only fields where labor compensation is commensurate with leveraged value-add?

Is it unethical to keep a chair warm when my boss didn't give me new tasks to do?

For other areas of life (immigration), I need to get more years of continuous relevant work experience.

I come to an office every day, but my boss just doesn't have enough to keep me busy. My job title is "Project Engineer", which is vague enough to cover everything from DLL debugging to Node.JS programming to network monitoring to evaluating Advanced Planning systems. The latest task is to do some online course in machine learning, even though he didn't specify how the company will need it.

On bad days, I feel useless. But I reconcile the situation to myself by saying it's basically a "basic income" (the salary is not high; the minimum that people on my visa can have). I could think about changing after I have the years of work experience, but years just come with patience, not with productivity. I feel like my situation isn't "fair" because my friends are so much more stressed, but I need the years, not the results.

I also do a lot of side projects and post them online (e.g. learning Chinese - http://pingtype.github.io ), but my contract and visa specifically state that I can't have any other paid work. So all my projects must be free and open source.

If another rest-and-vest person wants to comfort their conscience, I suggest reading more about Basic Income theories.

IMHO this is probably the first! thing you should do. To my own surprise people will give you money for your service even if you don't have a websites (and name, logo, slogan or anything else), and you send your 'product' via email.

And 3 out of 4 ideas don't survive these 20 calls - so you'll save a lot of time if you sell first and build later.

As someone who is responsible for bringing products to market on a daily basis, there is a considerable amount of strat being omitted which will better prepare you.

Pricing. Determine where you want to position your product in the market. Identify the competitors that compete on price vs the one's that compete on quality. Determine where you want to position your products and which competitors to go after. This should help you determine which customers you want to market towards as well. It also helps you determine the effort you can apply to each channel. [Spend more time on the difficult customer to obtain]. Michael Jordan didn't become Michael Jordan by practicing his dunk.

Companies like this have been around for years, and whenever I read about them I'm surprised that people would risk going to prison (or worse) just to get a discounted air fare. I wouldn't even carry a package for a friend unless I could see exactly what was inside, let alone carry a suitcase full of unknown stuff for a total stranger.

Also, an inevitable question when going through security checkpoints in some countries is "did you pack your own luggage". I assume that if you answer "no", you'd be subjected to a very thorough search for bombs or contraband.

Calling a company "Airmule" seems to be a particularly bad choice, since the term "mule" is commonly used to denote a person who carries smuggled drugs (sometimes concealed inside their body).

Get your PR and compliance straight if you want to avoid such pieces, don't complain afterwards while calling names.

I don't know anything about airmule's operation or China's customs/security, but the on-board courier industry is a legitimate one that has regulations and procedures that it's not clear the author of this article is aware of.

> "We have found contraband in [courier] shipments," says U.S. Customs official Bob Fischler, "but percentage-wise it is infinitisemal. And in any seizure we made, it was obvious that the on-board courier had nothing to do with it." In fact, at New York' JFK and at London's Heathrow airport, because of the sheer volume of courier shipments, all courier pouches go to a central location for clearance. The courier is typically dismissed before customs physically inspects the shipments.

When I was studying in Taiwan in the early 80s, the island's high tariffs motivated travelers to carry suitcases full of stuff--Walkmans, cameras, Italian shoes, etc. Contact a guy in Hong Kong, he gives you a bag, a guy in Taipei picks it up and gives you NT5000, enough to pay for your ticket.

I never got up the courage to try it myself, but friends did. My girlfriend did it once.

Looking back, I realize how exceedingly stupid this was. Had there been heroin inside that camera, you were going to prison for the rest of your life. They didn't (and still don't) screw around.

I heard all sorts of stories. An Australian backpacker was caught at Korean customs with 50 Rolex watches stuffed in his shirt. He was sent up for ten years. Numerous young Americans and Europeans busted for drug smuggling were rotting in prison in Taiwan, Korea, and Japan. At the time, with these countries technically allied with us against Red China, execution was not a politically feasible alternative.

This Mule thing is just another respin of an old practice. Best to avoid.

It's significant that the business is about shipments from the US to China. That seems to be hard. Getting stuff shipped from China to the US seems to be ridiculously easy and fast. You can order stuff off Alibaba and get fast delivery via China Packet, which is a postal service with really good rates for China to the US. Delivery in the US is via the USPS.The other direction is much more expensive and slower.

The US needs to renegotiate postal rates with China. China is still getting the "developing country" discount from the USPS.

This makes me super curious about the pre flight baggage controls. How do they handle someone who picks up the extra bag, but winds up not taking the flight?

With baby formula, i'd just return the bag and apologize, eating the $99. Heroin on the other hand, i could probably move at a steep discount. $1k or so, not worth the risk. $10 or $20k? hmm. The bag needs to be worth at least $1000 in the target country, just to break even.

it seems like pretending to be a stoner, and setting up enough to buy a plane ticket could get you a lot of money for $99. Fake id and a prepaid credit card aren't that hard to come by. It's not like the ID needs to pass TSA inspection, as you're not taking the flight.

Seems like a very risky business. If your customers are willing to be pasties, it'll be ok. but just a couple of sharks completely change the risk profile. Doing stuff that precludes government enforcement of contracts is just crazy crazy risky.

Looks quite shady, especially given we're talking about China. Anything being wrong with the package - not even drugs - that'd be insanely bad - but I'm sure there are many other things which require special papers to get into China, or are prohibited, and if something is wrong, it's the courier's ass on the line. I don't see how it could be worth the risk of being imprisoned in China. I mean it's one thing to be in a "gray area" as an American in the US, with all legal protections and ACLU and so on, and another thing doing the same in China...

And I wonder what TSA thinks about people transporting things that they have little idea about in their luggage?

reuven 2 days ago 0 replies      
I'm glad that the author of this travel blog is warning people against using Airmule. Someone is going to get in a heckuva lot of trouble.

First: I can only imagine, when checking my bags, getting the question, "Did anyone give you anything to bring on the flight?" and answering, "Yes, my entire 2nd bag belongs to someone else who is paying for half of my ticket."

That alone would be enough to give you extra-special scrutiny when checking in.

But let's assume that you get through security, go on your flight, and arrive. I've traveled to China many times, and have thus put my bag through the customs/airport scanner many times. If they find anything illegal -- and in China, that can mean all sorts of stuff -- you are in Big Trouble. I haven't ever seen anyone pulled aside when going through customs in China, but I don't envy them.

And sure, Airmule can say that they've inspected things, and that this is safe and fun, etc. Just try telling the Chinese customs officials that the drugs don't belong to you, but rather to a startup in Silicon Valley. I'm sure they'll be very attentive.

Airmule's site attempts to calm potential couriers' nerves by saying, "Read this Wikitravel article." (Reference: http://wikitravel.org/en/Air_courier) However, the article says, very clearly:

> You need to be very careful about the legitimacy of the jobs you take. The last thing you want is to be caught > transporting contraband (or worse) on a plane. A good way to avoid this is to use an agent (usually a > representative of the service you are working for), who will take you through customs and clear the contents.> Always check the reputation of the courier company before booking. None which are reliable and legitimate > would ever try to ship anything illegal.

Airmule doesn't promise to have an agent on the arrival side. They do promise that they'll "walk you through" things, but that's very different from physically being there in China and claiming the luggage and any responsibility for it.

The idea is a good one in theory, but as executed, it's half baked -- and might lead to executions of a more literal sort, if people aren't careful.

I haven't heard about air couriers for years, but I don't travel much. That said, I was under the impression that for basically all of them the package being couriered was never in the possession of the traveler but was instead packaged as freight and was delivered to the airline as such and handled as such at the receiving end. If the "courier" in question wanted to drop it off or pick it up themselves they'd still have to go to the appropriate air freight terminal.

If these folks are providing packages to travelers to be checked directly by the traveler then they're idiots and so is anyone who takes them up on the offer. If not for the defensive tweets, etc. I'd feel that (as someone else noted) this must be a satire of the 'gig' economy.

Cheers everyone, this is Sean Yang, CEO and cofounder of Airmule, the air courier startup with an admittedly strange name that you might have read about earlier today.

Is Airmule legal?

On Board Couriers (OBC) have existed over decades. Their purpose is to service cargo that needs to be delivered in a timely manner. Its quite an expensive service, often servicing auto parts, airplane parts, important documents, passports, NASA parts, etc. Costs can vary from a few hundred to thousands of dollars. To become an OBC is simple, just call any OBC company and register on their list. In our case, we simply request you to list your trip. The OBC companies size doesnt have to be the same as Fedex, UPS or any airline cargo department. As long as they follow the TSAs IAC regulation, only ship items from a Known Shipper, and have the cargo secured in a locked area inaccessible by outsiders. At Airmule, we have a surveillance camera over cargo 24/7. (49 CFR 1544.228, 1546.213, 1548.15, 1548.16, and 1548.7.)

So yes, OBCs are totally legal, as well as all OBC companies. I see many ask the answer to Did you pack everything yourself question. The answer is to be honest with Airline company No, I didnt. Im an OBC and I have the manifest, and I know whats inside my luggage.

Every single traveler will receive a manifest prior to receiving Airmule shipments Airmule is 100% responsible for the items on the list.There are items we dont accept if they dont comply with our policy or the destination country customs policy:

For example:

1. Powdery items.2. Pills, medicine, prescriptions3. Unclear liquids (wine, etc.)4. Live plants5. Animal products (elephant teeth, fur items, etc.)6. Counterfeit items

If the Shipment is for commercial purposes, we will declare through the proper channel. We contract with a professional customs brokerage company for every single country we service. In that case, couriers simple leave the item at customs, a receipt will be issued by Customs, and Airmule will handle it onsite, couriers will be relieved from duty at that point. Airmule is not Smuggling. We do pay duty on behalf of shippers. Our shipping policy is very restrictive with Senders responsible for all duty fees.

For those who likes the name, we cant do anything about it. Regardless of what we are called; it sounds like you dont want to work with us. We just hope one day, when you need something urgently, that Airmule is a better and more affordable option to help with delivery, and saves your day.

Airmule has been running for almost 2 years, weve helped thousands of travelers to see the world they never were able to see before. The deal we post is 100% authentic, but a very limited offer. In appreciation of your time to read this, wed like to give a bonus for $100 if you use coupon ISupportAirmule when list your trip. If you still have concerns, please do not hesitate to contact me directly at sean@airmule.com

Awesome analysis, I have added it to my favorites list. Around 1990 or so when I was in the kernel group at Sun and a team had just embarked on the multi-processor kernel work that would later result in the 'interrupts as threads'[1] paper. During that time there was an epic thread on email which was something like "What the F*ck does load average mean on an MP system?" (no doubt I have a copy on an unreadable quarter inch tape somewhere :-(). If it helps, the exact same pivot point was identified, which is this, does 'load average' mean the load on the CPU or the load on the system. While there were supporters in the 'system' camp the traditionalists carried the day with "We can't change the definition on existing customers, all of their shell scripts would break!" or something to that effect. Basically, the response was if we were to change it, we would have to call it something different to maintain a commitment to the principle of least surprise. This has never been an issue for Linux :-).

As a "systems" guy I am always interested in how balanced the system is, which is to say that I am always trying to figure out what the slowest part of my system is and insuring that it is within some small epsilon of the other parts. If you do that, then system load is linear with workload almost regardless of task composition. So disk heavy processes load the "system" as much as "compute heavy" processes and "memory heavy" or "network heavy." In an imaginary world you could decompose a system into 'resource units' and then optimize it for a particular workload.

This is great work in general and excellent historical research.

As an additional historical note: in Unix, load averages were introduced in 3BSD, and at that time they included processes in disk IO wait and other theoretically short-term waits that weren't interruptible. This definition was carried through the BSD series and onward into Unixes derived from them, such as the initial versions of SunOS and Ultrix. At some point (perhaps SunOS 3 to SunOS 4, perhaps later), the SunOS/Solaris definition changed to be purely runable processes.

(I'm not sure what System V derived Unixes such as Irix, HP-UX, and so on did, and their kernel source is not readily available online for spelunking.)

As of early 2016 when I last looked at this, the situation on FreeBSD, OpenBSD, and NetBSD was somewhat tangled. FreeBSD load average only included runable processes, but NetBSD and OpenBSD counted some sleeping or waiting processes as well.

Under Better Metrics the author discusses ways of drilling down to find the source of a high load average. I feel like this section should mention `atop`, which is imo a really underrated single-pane-of-glass view into everything your system is doing, now and historically.

If you haven't tried `atop`, give it a go.

This historical analysis in this article though is great, because while Load Average has been an oft discussed and we'll understood topic for a long time, the decisions that got us there are not.

Several years back the company I worked for ended up picking up some work for a client. Every quarter we'd download a huge trove of TIFFs from some source, and then do some image conversion work before shipping transferring them to the customer's infrastructure.

There was a java application that powered the logic side of things, calling out to ImageMagick to do the actual processing and conversion. For whatever reason, after careful benchmarking we settled on a java thread count that happened to get us the peak throughput, but also caused system load average to hit around 400 and keep steady at around that level.

The day that happened, and I could show that no application on the server took a performance hit, was the day that I finally persuaded my boss that load average is an interesting stat, but it's not the be-all and end-all, and that a high load average doesn't necessarily correlate to an actual problem.

sreque 19 hours ago 1 reply      
One source of high load average spikes that I've seen in my job is when a process crashes and generates a core dump. While the core dump is being written, all threads in the process are in the TASK_UNINTERRUPTIBLE state even though they are doing absolutely nothing, and as such they all count towards the load average as if they were spinning on on a CPU core. If the total virtual memory of the process is large, say in the multi-GB range, coredumping can take on the order of a minute, and Linux will report an unreasonably high load average if that process had a lot of running threads.

Things like the above scenario make me treat the load average metric with a lot of skepticism. I would much rather use other metrics to infer load.

Good article. However, it is missing the reason why load averages include tasks waiting for disc/swap.

One of the things that the load average is sometimes used for is to work out whether it is appropriate to start some more processes running on a system. For example, make has a "-l" option, which prevents more parallel jobs being run while the load is above a supplied number. When a system is thrashing due to insufficient RAM, then the load average will be high, and this option will appropriately prevent more tasks being started which would make the thrashing worse. If the load average was just based on CPU, then it would be low while thrashing, and using that make option could lead to complete system collapse.

This analysis cleared up a mystery for me. I've noticed that when a server app is under heavy load in Linux, the load average goes high if the bottleneck is the CPU or the disk, but the load average goes low if the bottleneck is network resources (like databases or microservice calls). I know why that happens, but it's very unintuitive and it confused me when I was new to Linux. I thought load average would measure the CPU load only. Now I know the historical reasons for measuring system load instead of CPU load.

I kind of like it the way it is since it's handy to be able to distinguish network load from CPU+disk load just by looking at the load average. However, since the load average includes other stuff as well, sometimes I still don't know what the load average really means.

Page swapping seems like it makes a lot of sense to include in the load average. Disk I/O seems like something more towards the opposite end of the spectrum, though TASK_KILLABLE (https://lwn.net/Articles/288056/) presumably mitigates this where used.

OT: what could cause a system to have a load of 1 when idle?

I have one (unimportant) Linux system that idles with a load of exactly 1. The issue persists through reboots. It is a KVM virtual machine and qemu confirms nothing is going on in the background.

Any ideas how to find out what's causing it?

Working in open office plans is simply awful.

Personally I believe remote work, for any tech-enabled employer, makes the most sense. The impact on infrastructure by removing commuting alone could maybe help save the planet. And our collective sanity.

Wouldn't it be nice to have ISPs that can provide an infrastructure that could actually support that? I think so.

The hideous effects of cluster-fucking hundreds of thousands of people daily just needs to stop. Tech companies are guilty. They're huge and, humbly opined, are idiots for making it worse and not really needing to. Top that off with an open floor destination and.. damn, work is beat.

Apple has insisted in presentations to the city of Cupertino that the open floor plan designs are conducive to collaboration between teams, per Bloomberg. But the high-level executives, including Apple CEO Tim Cook, are exempt from this collaborative environment and have offices on the fourth floor of the new building.

See, this is exactly what's wrong with open plan offices in most places. If a CEO honestly believes open plan is better for collaboration, then they need to eat their own dog food. That CEO needs to be sitting right in the middle of things. If they find they can't get anything done as a consequence of the collaboration they are in the right place to take action to fix that. And if they are able to achieve productive outcomes, they are also in the right place to argue against people who say it's not possible. Letting upper management avoid all the downsides of the open plan layout causes problems with it to fester and will bring overall worker satisfaction and productivity down. In short, it is bad management to treat management in a special way.

My company only has offices for upper management. Everyone else is at a table. Tables are arranged in groups of four.

Now, I get it, some people like open office environments. Good for them.

Me? Well, I've told many coworkers that I can't work from home because I wouldn't work from home. There are too many distractions at home, so I need to be at the office to be productive.

But this open office?

There are days where I am convinced I would do more work, be more productive, and feel more satisfied if I worked from home.

I went and bought some noise cancelling headphones. They help, but definitely not enough. My table is by the main door. With a room of 40+ engineers, there's constant distracting traffic. Some people make snide comments about my choice of operating system, keyboard, language, editor, typing noise, attire, whatever. Or to chat about the games that I missed last night, something happened at the not-company-sponsored-happy-hour that I didn't get the invite to, or something about lunch that, you know, you should have been there and if only you wouldn't leave the office for lunch. Or about how your racing car is in for the shop because, well, actually I don't even care why. It's just in the shop (I know! you told me!) and you expect me to care about car parts too, and shame on me for not knowing the difference between a maserati and a miata.

On the other hand, any time I mention to my boss that I'd like at least a cubicle the response is "it's not going to happen". Thanks, boss! I'm glad you've got my productivity concerns on your plate. I'm glad they can just, you know, be heard. Not addressed, just heard. It's really helpful to be heard. All day. It's real helpful to hear everyone's discussions while I'm trying to do work.

Honestly, guys, if you like an open office environment, that's good for you. Not everyone wants one and not everyone works well in one.

I worked at Apple during the years when the company designed and built its first campus at 1 Infinite Loop in Cupertino. As I recall, Apple R&D employees were considered stakeholders and participated in the design of the interior spaces. Apple wisely decided to give each engineer a private office. There were open areas near the offices with comfortable furniture and whiteboards for engineers to meet and collaborate. I worked in one of these buildings from 2001-2007, and I can confirm that the work areas were beautifully designed and ideal for fostering productive work. It's sad to hear that Apple apparently abandoned this approach in its new campus.

Man, I remember in college when we would be working long hours in the library on a computer lined up in a row of computers. Every one would be intensely working on what they needed to. Sometimes two would work together. This was especially true before presentations when we were trying to put our stuff together. It was neat. It was collaborative. It was fun. And we were happy.

Open floor plan is reminiscent of those days, but it isn't working. And I cannot figure out why. What's missing? Intensity? Work? Stress? Team building therapy? Or just trust? Whatever it is I hope we figure it out.

Headphones are a poor solution to the noise problem in open offices. I find it uncomfortable to wear them for 8 hours at a time, and it means I can't overhear the conversations I do want to overhear. Sitting elsewhere only works if I have a task I can do on a laptop; for serious development work I need a lot of screen real estate. That solution also has the same problem as headphones where I might miss important conversations because I'm too busy hiding from noise created by people doing work completely unrelated to mine.

There's a pretty happy medium, 2-10 person offices (with 4-5 being the most common size) with glass walls. Google used to have a lot of these before completely open plans became en vogue, and it was very rare to hear complaints. They allow frequent interaction with your most common collaborators while blocking out conversations from distant teams. They reduce visual distraction while still allowing in lots of natural light and inviting conversation. Doors were usually left open, so it was pretty comfortable to walk into another office and start up a conversation.

With the giant, open, chicken-farm style floorplans, people feel too self-conscious about dozens of people overhearing to have small 2-3 person conversations near their desks, which means more formal meetings with all the associated overhead, and fewer impromptu questions like "hey does anyone know of a tool to do X?" And then you're still more distracted anyway due to all the typing, people walking by, large groups being loud when gathering to eat lunch or go to a meeting together or whatever.

I only see two advantages of completely open floors: slightly cheaper (glass offices can be made almost as dense, but not quite, and I guess the glass partitions aren't free), and better circulation to dissipate bad odors more quickly.

Because private offices offers control over your working environment; if you need to collaborate, use a conference room, if you need a quick discussion, call them up on Slack.

I'm not going to touch wether or not the CEO has earned the best working environment, but let's bring attention to the fact that the CEO is promoting less control over your working environment for his employees and claim open-office plans offers all kinds of benefits, while the C-level management chooses to opt out. Either that's very noble of them to sacrifice all the benefits of open-office, or they're being a bit disingenuous about why almost everyone else gets an open-office plan.

My company recently switched to an open floor plan. It's done nothing but increase distractions and office gossip. Everyone I know tries to get away from their desk as often as possible. Ducking into side rooms, attempting to work from home, and just plain using any excuse to escape the zoo.

Management loves open plans because it's the cheapest seating arrangement. They claim that it will increase collaboration while exempting themselves from having to deal with the environment. The truth is that just being able to see someone without walking over to their desk isn't going to magically make you communicate with them more or make your output higher. Some people like open floor plans but it's been my experience most people don't and just grin and bear it while slowly dying inside.

This is just an overused cover-up story to avoid stating the real reasons which is cutting costs and monitoring employees.

They use "collaboration" so that you can't voice your opposition to it easily.

If you do that they will beat you with the "not a team player" and "not a culture fit" sticks.

Then in reality unhappy employees sit next to each other with noise cancelling headphones whose job has been unnecessarily harder than it already is because now a part of their mental focus and capacity is actively going towards ignoring distractions.

Why don't they want to be as productive and collaborative as their reports? Conference rooms and phone rooms are just as available to them as they are to the rest. They can probably even afford much better head phones than the rest.

I just don't see enough of a difference to justify it.

cordite 15 hours ago 0 replies      
I've worked in both, and both have their benefits. However, my evaluation of open office may be biased because we also use slack.

Regarding open office plans:Focus does suffer in an open layout. Creativity does suffer too. In the face of a fire in production, an open office creates a low friction environment for task distribution to handle it. A factor that makes up for this is that we can work from home one day a week. I find these times to allow me to be most creative for planning long term solutions. Occasional remote work is possible and effective thanks to several technologies including Slack.

Regarding individual or paired offices: focus is easy to accomplish, and it is easier to be creative. It can be quiet, but it sure feels lonely when my team members take 3-6 minutes to walk to. Unfortunately, meetings, ad-hoc visits, and email were the communication methods here. Remote work was near impossible and impractical with just email for peer involved processes. This was also in a very corp-legacy environment and my ability to make an impact was unsatisfying. So I feel my creativity was often wasted and unvalued.

Overall, I think I like what I have now, which is mostly open office, but still occasional time for individual creativity.

The open office arrangement works for some industries but for others, each company would need to evaluate how specialized their workforce is to choose a suitable arrangement.

I would prefer a glass office with the freedom to have it closed much of the day without any "judgement".

I am developer with an office now, but if i close the door I seem to be keeping people off, and not "social" or "accommodating". Leaving the door open exposes me to a lot of distractions (noise, visual-people walking etc, people just stopping by or spying on me) which are unhealthy and reduce my productivity. I have since learnt to ignore as much distractions as I can.

Working previously in an audit firm, the open space worked well, because there is constant collaboration with multiple audit colleagues and all tasks complement each other hence the need to constantly keep tabs. But in development,if I have my specs or requirements , I don't need to keep in touch unless when giving updates, requesting for a resource, asking fr help or something else that is really pressing.

We have screen walls (~2 meters) around teams of 2-4 people. I think 2-4 people is a decent compromise, you get friction-less cooperation with the people you work with but you don't get to overhear 20 different conversations about what someone did on their weekend.

I am still bothered by other people's conversations across the screen-walls though, and I prefer to not listen to music all day.

Our CEO is sympathetic to the issue with open offices and maybe if we move to another place it will have a different layout, but converting an open office to separate rooms is not that easy. Does anyone have any suggestions when management would actually accept taking measures to avoid the negatives of open office plans?

Oh, please. A trip to Wikipedia would have told you that[1]:

> A systematic survey of research upon the effects of open-plan offices found [] high levels of noise, stress, conflict, high blood pressure and a high staff turnover. The noise level in open-plan offices greatly reduces productivity, which drops to one third relative to what it would be in quiet rooms.

> Open-plan offices have frequently been found to reduce the confidential or private conversations which employees engage in, and to reduce job satisfaction, concentration and performance, whilst increasing auditory and visual distractions.

Further, open office plans spread disease more readily[2]:

> elevated risks [for disease] were found among employees in all three traditional open-plan offices

An open office floor plan robs you of the ability to control the noise level in the environment. There is literally no way for me to convince enough of my coworkers that they should:

* Either take their phone with them, or silence it if leaving it at your desk.

* Stop having meetings in the aisle immediately next to my desk.

* If you're going to video conference in the meeting rooms, and have the other end at full volume, close the damn door. If you don't know enough about video conferencing to understand what a feedback loop is, and want to spend the first 10 minutes of the meeting generating them, close the damn door. Stop looking at me like I'm rude when I close the door for you.

Calling people out gets a typical "oh, sorry", but not an actual change in behavior.

Maybe it encourages me to talk to the team nearby. Maybe. But is it worth the losses? No. (The team next to me is sales. They're not bad people, but they are fairly noisy. (And I'm sure they'd say the same of us, in fact!))

Apple has the money to afford whatever it wants. If it's like any other place I've seen, I expect there's longstanding communication of one or another sort from high performers that they want distraction-free environments.

From what I've observed of such high performers, they are not anti-social nor anti-collaborative, nor are they "crippled" in either respect. Rather, many of them are the most capable in these areas, because they actually pay attention and focus on getting things done -- and done as well as time and resources allow.

The fact that Apple, like many workplaces I've observed, chooses to ignore this and push a paradigm that increases their stress and decreases their effectiveness and efficiency?

Well, as I learned in my own experience, over the years: This is just a fundamental level of dis-respect.

I don't know anything about Apple work internals, specifically; the last time I intersected with those peripherally was in the early '90's.

But when you blatantly disregard what employees tell you -- and in this case, "professional" employees who have a high degree of training and awareness about the tooling they need, including their work environments, to be most effective. Well, that's just disrespect.

And employers who persistently engage in such, deserve what they get. I hope -- because at some point, this counter-productive... "ideology" needs to die.

P.S. Those employees that want cubicles or open-space? Fine, give it to them. I don't want to dictate environment, either way.

Trust your employees to select what works best for them.

And measure the results. Objectively, not in the typical performance review ex post facto rationalization and justification.

In my own experience, top performers cautiously (politics) leapt at the chance to work from home and otherwise gain undistracted blocks of time to adequately focus on complex problems and program management.

Those who embraced the cycle of endless meetings, interruptions -- including environmental -- and superficially-addressed delegation? They faced the same problems, month after month, cycle after cycle.

We're going one step better at my work with our new/future office, "Activity Based Working". All the trappings of "open plan" but with even more features to make Government work more soul-crushing and complicated.

One office, with desks for 80% of the staff (because the other 20% need to take the hint and resign). Each desk only has one monitor, keyboard, and a mouse. If you've got certain ergonomic requirements, or need a colour accurate monitor, or a large monitor, or several monitors then you're just a naysayer who is obviously not productive enough to understand the ways of the future.

No one 'has' a desk, instead you grab your laptop out of your locker each morning and go find one. Or you might be allocated a desk via a morning raffle, not sure on this one yet. At the end of each day you clean every surface with alcohol wipes, which you then queue up to place in the singular bin that services the 300ish staff. Anyone who sits at the same desk twice will have to complete "Activity Based Working" training, in much the same way intoxicated road users may attend a DUI class.

There will also be no car parks for staff, who are being encouraged to use public transport. The fact that this public transport doesn't actually exist yet is just a "growth opportunity", but who's growth we're referring to here is not yet clear.

This might all sound like a joke, but the sad thing is it's 100% serious. Literally all of the above has been set in stone by minister that our department reports to.

Being alone and hiking and camping in the wilderness without human contact for longer period can be amazing experience. There can be initial anxiety and intense desire to go back after romance goes away and your internal shit comes to light. When there is constant need for do chores to survive but also free time and no human contact, no books, radio or music, mind gradually settles into itself.

It's like coming from bright light into a dark room. Gradually your eyes adjust and you start to see more. Coming back into the civilization is similar to someone pointing flashlight into your eyes. So much external triggers for behaviour. Realizing that I'm not actually me with other people and I'm disappearing into network of others. Me with others is mainly just bunch of triggers that fire based on conditioning.

If I can feel intense otherworldliness from just week or month alone, I imagine that if someone spends decades alone, civilization might seem like miserable alien ant colony. Everybody is responding to commands from others and carrying stuff they don't care about.

ps. It also can trigger psycosis, panic or some kind of madness (prairie fever, cabin fever) in some people. Romanticizing it as escape from all your problems might give people the wrong idea.

It baffles me that people think it's so shockingly outlandish that there are people who don't reactionarily buy into the tribalistic pressures around us to simply act like everyone else. Humanity is not homogeneous, yet some notions like these are always projected out to be considered an immutable, inescapable constant. I can only guess that's that same fear of being different shining through.

I presume that on sites like this, there's a higher percentage of people who attempt to be more intentionally decisive about themselves and their lives. We don't necessarily have to toss out everything like Knight did, but looking at life and all the weird social rituals and expectations built up, the dichotomy between those and what seems actually beneficial becomes apparent. That conflict causes a choice, we would seek to do the "better" thing, and that draws many people outside the superficial social norms.

I especially bristle at this quote: "Why dont we want to be alone? Because the stuff thats down there is stuff you dont want to see." Anybody who tries to intentionally better themselves knows what's down there. You have to assess what you are if you're going to change. Sure, you can deny and hide from all that and simply find comfort in floating along with everybody else in social inertia, but that seems to me to be a shameful waste of those conceptual abilities which (apparently) make us uniquely human.

I have the impulse to become a hermit myself, fundamentally because I'm tired of living up to other people's ideologies: going through schools and finding a job in a cubical. getting married at the right age and then raising the right amount kids, saving for their college fund and then for retirement.

but why?

I can't help but compare with my surroundings, even I have quit Facebook for many years. I can't be myself when I'm around others, but become a money maker for things I don't need. I can't concentrate on what makes me happy.

I recall what made me happy. it was when I finally understood some papers, some equations, some code. I just want to find a quiet place to do these. I hope to become an awesome painter and a guitar player too.

I just want to have enough to survive and focus my energy on these things. I don't care if I have successful kids or fancy cars.

The idea of introverts and extraverts being distinct groups of people with completely different neurological responses to social situations is a largely false one, created by self-help woo merchants to unhelpfully pathologise the feeling that EVERYONE has from time to time that they want to be left the fuck alone.

You know what? It's a normal, neurotypical part of life as a homo sapiens to want to be by yourself sometimes. And equally, it's a normal, neurotypical part of life as a homo sapiens to want to socialise sometimes.

We're a weird species like that, the way sometimes we want something and other times we want the opposite.

The title IMO is far more interesting and thought provoking than the actual story. So this guy lived in the woods somewhat near people, and stole to get by...

I've personally always been fascinated by the topic as I have met several hermit monks, have a friend who lived as one for half a year, and contemplated it for myself. The history of religious asceticism and hermits is quite interesting, and many of history's most famous philosophers/religious leaders/prophets were either hermits, or had periods of reclusion. And nearly every single religion has these hermit figures.

Anyhow, the downside is that being alone is tough. Physically and mentally. Humans are social creatures. However I have personally benefited from periods of isolation and reflection, even if I'd much rather be around others.

We live in a world in which who we are is defined by what we do. We are a role - parent, engineer, carer. Strip that away and all that remains is a who. That's the reward of solitude: a situation wherein you have nobody to bounce your 'self' off, nobody to define yourself in relation to, allowing you to surface.

Turns out that who you are is simply a sequence of reactions to experience - the external kind as well as that which bubbles up internally. Rather than terrifying, this should be seen as profoundly liberating.

My personal theory for explaining hermits throughout history is simple, these people had/have aspergers. I have aspergers myself, and I can very easily see someone who has aspergers who for whatever reason no longer wants to socialize anymore getting up and doing their own thing out in isolation. I don't truly believe that any neurotypical person, and for that matter many aspies could do it, but if you're brain is wired in a way that socialization doesn't provide that reward that it does for most other people, either because you don't understand social interaction and have no desire to learn the rules so you can play the game, or simply because you have discovered the rules and simply have no interest exhausting the effort, going out into isolation and spending the rest of your days pursuing other things that give you fulfillment.

Can't say I'm a fan of the author's choice for title of this post. It's Chris Knight's story, and nothing in this post presents any evidence for anyone else at any other time, aside from this single sentence "Think of Jesus, Mohammed, and Buddha: they all spent very long periods of time alone before introducing their religions." I totally believe there have always been people who want to be alone sometimes. Pretty much everyone wants to be alone sometimes. But ugh, this sentence & title seem to strain credulity and are so completely unnecessary and tangential to this story.

I find it interesting that silent retreats work for so many people. While I do get some benefits from meditation it doesn't really lead me to terrifying situations. From time to time it feels like I am having some epiphanies wrt to my shortcomings but meditation seems too gentle to call those moments a confrontation. There is always this nice, cool distance between me and my thoughts. Throwing me into an impro theater group might be more beneficial (and terrifying).The required spontaneity would force the "actual me" to live through uncomfortable situations and perhaps grow.

His slide on "learning to learn" has a goal of removing the ML expert in the equation. Can somebody who's more of an expert in the field comment on how plausible it is?

Software engineers need to know to recognize and classify problems in CS. You need to know what algorithms and data structures exist, what their properties are, and what they are called. The areas that come up will come from Math and Computer science (which are closely related). A solid computer scientist person knows how to derive some Dijksttra algorithm from first principles. A good software engineer recognizes the problem at hand, and recalls the algorithm to pick when presented with the problem.

What is that problem in front of you? Gradient descent? Tree traversal? Multiple dispatch? Path finding? What structure represents the data or algorithm? Ring buffer? Blocking queue? Bloom filter?

You rarely need to remember a pathfinding algorithm or trie implementation by heart. What's important is that you a) recognized the problem at hand as "path finding", "bin packing" or whatever. Terminology is important here. The good software engineer needs to know the proper names for a LOT of things. Recognizing and labeling problems means you can basically look up the solution in no time.

So CS is definitely very relevant for software engineering - but you need a broad understanding instead of a deep one.

There is always the argument that a lot of devs basically to monotone work with SQL and some web thing in node and rarely even reach for a structure beyond a list or map. That's true - but sooner or later even they bounce into a performance or reliability issue that's basically always due to incorrect choice of data structure or algorithm. I'm only half joking when I suggest that most of todays "scaling" is compensating for CS mistakes in software.

I don't understand why the author is so suspicious of formal methods. Other engineering disciplines are based on the application of solid, well-understood principles from the natural sciences to practical problem domains. There are few solid, well-understood principles in computer science that are directly and obviously applicable to software engineering so far.

I vigorously contest the idea that software engineering cannot be rigorous and so shouldn't try.

Here's the graphic transcribed as text for non-English speakers.

Software Engineering: Requirements, Modifiability, Design Patterns, Usability, Safety, Scalability, Portability, Team Process, Maintainability, Estimation, Testability, Architecture Styles.

Computer Science: Computability, Formal Specification, Correctness Proofs, Network Analysis, OS Paging/Scheduling, Queueing Theory, Language Syntax/Semantics, Automatic Programming, Complexity, Algorithms, Cryptography, Compilers.

In my opinion, some of those could be on the other side of the line (estimation could be CS, language syntax/semantics and network analysis could be SE). But I agree with the general division.

I studied Electronic Systems Engineering, but somehow always found jobs in software companies. One problem I struggle with is the division between DRY (Don't Repeat Yourself) and WET (Write Everything Twice) coding styles.

Most programmers hate it when code is repeated. They prefer to spend days trying to integrate external libraries instead of just copying the necessary functions into the main branch. There are good reasons for this (benefiting from new features when the library gets updated), but there are also risks (the code breaking when the library gets updated).

Software Engineering priorities include Safety, Portability, Modifiability, and Testability. I interpret that as a WET programming style. "If you want it done well, do it yourself." There's no arguing about responsibility then - the code is mine, and I should fix it if it breaks.

I've seen similar articles to this one, both in print and on web sites. I used to explain it to people as the difference between 'coders' and 'engineers' but I think my own hubris at having a degree got in the way of my thinking on it.

Over the decades I've met a bunch of people who program computers for a living, and there is clearly a spectrum where on one end is a person who spends the weekend benchmarking different sort algorithms under different conditions for the fun of it, and the guy who left the office at 5PM once an integration test passed on a piece of code that he pasted in from stack overflow was deemed to have no regressions. There are many different disciplines that have such a wide dynamic, from chefs who spend their weekends trying different flavors to cooks who take frozen patties out, reheat them and serve. Painters who throw human emotion into a painting and painters who lay down a yellow line on a road according to a template for $20/hr.

It seems to me that most, of not all, of the 'theory' stuff in computer science is just math of one form or another. This is not unlike all the 'theory' stuff in electrical engineering is just physics. You can do the tasks without the theory, but you rarely invent new ways of doing things without that understanding.

But just like carpenters and architects there is a tremendous amount of depth in the crafting of things. That brilliance should be respected, college trained or not, so trying to 'split' the pool doesn't lead to any good insights about what being a good engineer is all about.

This is quite inaccurate. Hardware directly influences software. "if" statements, functions, and threads didn't exist at one time, and all require explicit hardware support.

Software engineering is where the rubber hits the road in terms of requirements definition, creating a solid design, fitting stuff into an existing legacy environment (SAP anyone? Java EE?), iterating prototypes with stakeholders... and usually in large corporations. It was out of many years of budget overruns in defense procurement that software engineering cornerstones such as CMMI emerged.

To me, the essence of software engineering is that 20% is about building the 'good' solution itself, e.g. architecture, code, release / deployment, ... the remainder of the engineering is navigating / tolerating the inherent corporate messiness of politics, opinions, power, and everything else... engineering the solution is the easy part; engineering good requirements and quality is tough.

The author has a slightly funny use of the word engineering. If you look at its use in a conventional field like making cars then the science bit is the basic physics and chemistry of how gasses expand etc, the engineering is designing the machinery so the brakes work, the engine produces enough power and doesn't break and the like and then human issues like whether the workers go on strike or the end users are idiots and crash are not engineering.

Similarly I'd say in software the engineering bit is making reliable systems that are fault tolerant and secure and so on and then the people bits like the user interface are something like design and psychology, not engineering.

Let's revisit the definition of "engineering", in a simplified form:

 Science -> Engineering -> Technology
Engineering borrows scientific[1] knowledge to create[2] technology[3]

[1]: or empirical knowledge

[2]: or maintain or implement

[3]: or processes

The relationship between science and engineering has been clear for a while now, even before the appearance of software engineering.

There's a lot of science at work in existing software, so it would be inaccurate to say that software is "unscientific". However not many people get to work on those projects.

A vast majority of people can make a decent living working on user facing technologies built with existing technology. At that level appealing to non-technical stakeholders has much more weight than applying engineering rigor.

But that's not the reality for everyone.

These are complicated terms. Harvard's CS was part of their Applied Math department. There are Applied Maths of scheduling programmatic Engineering outcomes for sure. Fred Brooks taught us all that.

I studied Russell, Godel, Tarski and Quine and then compiler and runtime logic (as a Philosophy major). Back then CS was mostly a realm of 3-Page proofs on alpha renaming or newfangled Skip List speed/space utility.

As an old VAX/Sun or 512K/DOS C programmer working in DC for decades around lots of TC, datacenter and transaction processing folks, an SE MUST have basic speed/space, set theoretic, programming by contract, data integrity and MTBF abstractions in their heads while they plan and develop. Both accuracy and performance against test and measure just matter for the business cases 24/7.

Content software developers patching together framework components on 2 day schedules for consumer Web bloatware rarely understand something like data integrity needs of billing system logic embedding in redundant switches failing over on rough schedules. Typing commands is not even Software Engineering.

Software Engineering is not an individual identity phenomenon. SE is how groups show responsibility for stakeholder outcomes unrelated to paychecks. First rule of SE is everyone on the team passes the bus test. Nobody is essential. Unless we seek luck, we can't improve what we don't measure. Learning how and what to measure takes real training and group method application. So many out there never know what they are missing.

Business competition minus lucky windfalls is largely based on COST ACCOUNTING. Successful operations will discover heat dissipation costs challenges. Basic CS speed/space, contract covenant assertions, data integrity and MTBF logic in Software Engineers translates very easily into understanding business innovation problems.

I neither agree nor disagree with the article. I think it conflates a lot of stuff.

But look, what the math and science sides of the room throw at us definitely informs the engineering. In every other engineering principle from architecture to ditch digging, there is a feeder system from a variety of mathematical and scientific disciplines. While many other engineering disciplines are well established, they are not immune to this and in general don't begrudge it.

Doctors are required to keep up on the state of treatment. Architects need to keep up on materials science AND new mathematical modeling techniques and tools. Car designers care about new discoveries in lighting, battery and materials technology.

Here's a good example of the kind of stuff we all should be on the hook for. I've tried to push this paper up to the front page a few times now because it's roughly the same as if someone walked up and calmly announced they'd worked out how to compress space to beat the speed of light:


Folks are generalizing linear sort algorithms to things we thought previously were only amenable to pair-wise comparison sorts without a custom programming model and tons of thought. No! And then a famous engineer-and-also-mathematician made an amazingly fast library to go with it (https://hackage.haskell.org/package/discrimination).

We're seeing multiple revolutions in our industry made of... well... OLD components! While deep learning is starting to break untrodden ground now, a lot of the techniques are about having big hardware budgets, lots of great training data, and a bunch of old techniques. The deep learning on mobile tricks? Why that's an old numerical technique for making linear algebra cheaper by reversing order we walk the chain rule. O(n) general sort is arguably bigger if we can get it into everyone's hands because of how it changes the game bulk data processing and search (suddenly EVERY step is a reduce step!)

We've similarly been sitting on functional programming techniques that absolutely blow anything the OO world has out of the water, but require an up-front investment of time and practice with a completely alternate style of programming. But unlike our fast-and-loose metaprogramming, reflection and monkey patching tricks in industry these techniques come with theorems and programmatic analysis techniques that make code faster for free, not slower.

Even if your day job is, like mine, full of a lot of humdrum plug-this-into-that work, we can benefit from modern techniques to build absolutely rock solid systems with good performance and high reliability. We could be directly incorporating simple concepts like CRDTs to make our systems less prone to error.

It's our job (and arguably it's the hardest job of the field) to dive into the world of pure research, understand it, and bring what's necessary out to the world of modern software. That means more than just tapping away at CSS files, or wailing about NPM security, or shrugging and saying, "Maybe Golang's model is the best we can hope from in modern programmers."

"I ended up between the Supermicro SSG-6048R-E1CR60L or the SSG-6048R-E1CR90L the E1CR60L is a 60-bay 4U chassis while the E1CR90L is a 90-bay 4U chassis. This nice part is that no matter which platform you choose Supermicro sells this only as a pre-configured machine this means that their engineers are going to make sure that the hardware you choose to put in this is all from a known compatibility list. Basically, you cannot buy this chassis empty and jam your own parts in"

This is a major departure from the Supermicro business model and practices and basically broke all of our next generation expansion roadmaps.

This was not a technical decision - it is the same old economic decision that every large VAR/integrator/supplier has succumbed to for the last 30 years. They aren't the first ones to try this trick and they won't be the last.

We (rsync.net) are not playing ball, however. After 16 years of deploying solely on supermicro hardware (server chassis and JBODs) we bought our first non-supermicro JBOD last month.

There are a couple needful tweaks to this BOM for anyone wanting to follow this..

Only populate one CPU socket. Zone allocation between two NUMA nodes is kind of hard, especially since Ubuntu 16.04 zfs is pre- OpenZFS ABD where memory fragmentation is reality.

I would recommend better NICs like a Chelsio T5 or T6. Aside from better drivers and a responsive vendor, you can experiment with some of the iscsi offloads or zero copy TCP.

Supermicro seriously under-provisioned I/O on that chassis. I'd add LSI/Avago/now Broadcom cards so you can get native ports to every drive. Even if it's just a cold storage box, it will help with rebuild and scrub times and peace of mind. The cost of this is not bad compared to the frustration of SAS expander firmwares. 2x24 or 3x16 and 4 drives on the onboard if you can skip the backplane expander. Supermicro will usually do things like this if you insist, or an integrator like ixSystems can handle it.

More subjectively, I would also recommend FreeBSD. It seems their main justification for Ubuntu was paid support, which can be had from ixSystems who sell and support an entire stack (Supermicro servers, FreeBSD or FreeNAS or TrueNAS, and grok ZFS and storage drivers to the tune that they have done quite a bit of development.

> I purchased these units through a vendor we like to use and they hooked us up, so I wont be able to share my specific pricing. (...) If you build the systems out on there youll find that they come in around $35,000 (USD) each.

That devided by 52 x 8 = 416TB is 0.084$/GB. For comparison, the Backblaze Storage Pod 6.0 [1] claims 0.06$/GB for the version with the same hard drives. Although this version has a bunch of extra features like 2 x 800GB SSD's for ZFS SLOG, 8x more RAM for a total of 256GB, etc.

We bought our initial 2 TrueNAS servers from IX Systems (SuperMicro) back in 2011, have been upgrading over the years and they have been very reliable servers.

Currently each server has 63 drives (4TB HGST NL-SAS) with 1 hot spare, configured as RAIDZ.

Right now there is 200TB of usable storage, we initially started with 29TB and have been expanding as needed when it hits about 79%, I buy 18 drives roughly every 6-8 months, 9 drives per server and expand the pool.

To say that we never had issues is lying, we did have some major issues when upgrading from versions, but this was early on, now it is a rock solid storage system.

Although there is less than 300 active users connecting to the primary server, there is a lot of very important pre & post production high dev videos.

Reboot with 63 drives is around 10 minutes or less.

Resilvering could take 24-48 hours, depending on load, depending on how much data the failed drive contained.

Performance has been great, reliability has been great, support has been great.

Sadly IX Systems can no longer provide support after the end of this year, they've extended support beyond the expected lifetime of the hardware.

Zfs on linux and huge single servers, what could go wrong?

It's like a blog written by a 22 year old straight out of college that's never dealt with a real production deployment/failure

Zfs on Linux has data loss bugs. There's at least one unpatched and there are bound to be more.

Single huge servers eventually fail. Maybe it'll be a drive controller. Maybe it'll be CPU or ram with bit flips as a side effect. Downtime would be the least painful part of the eventual failure.

Biggest question: why?

At that scale something like Ceph would be more reasonable. Just because ZFS can handle those filesystem sizes doesn't necessarily mean that it's the best tool for the job. There's a reason why all big players like Google, Amazon and Facebook go for the horizontal scaling approach.

To a certain extent, this how we used to travel back in the day.

You hung out in a hostel, had conversations with other travelers (instead of thumbing through Instagram), and let the randomness of other people and life, not apps, dictate your itinerary. You walk down a street, "oh hey that looks interesting", and wander down a quiet alley that leads to cute cafe, or jump in the back of a tuk-tuk headed to a waterfall that may or may not really exist, but who cares? You're riding the wave. One of the main reasons for travel/holidays is to break from routine, and the single most significant one can do, bear with me Silicon Valley, is to put away that smartphone. Try exercising your intuition instead of apps.

Many folks nowadays have optimised their lives so much that they've needed to create a noise-generator to bring back some humanity.

This is great. I think that the illusion of time speeding up as we get older is due to getting into a routine where we do the same thing every day, and the brain begins compressing memories as our everyday experiences become less novel. Using a "randomizer lite" program to shake things up might be a good start to breaking the routine.
owenversteeg 1 day ago 2 replies      
Ah, but what was his source of randomness? Perhaps he didn't have enough entropy and now he's got to do the last few years all over again ;)

I think I naturally do a bit of that myself: whenever I have some empty time, I fill it with something "random", only instead of choosing randomly I often choose the cheapest option. For example, I once booked a flight to Iran departing hours after I bought the ticket, simply because it was the cheapest option for an interesting place to fly (under $180 round-trip.)

I think the design choices really impact the end result, though. One minor design flaw might result in completely eliminating a whole lot of interesting places or things, which is what I'd be scared of. For example, that cheap fare to Iran was only on one travel search site, which didn't have an API. By selecting one booking website as an API, and letting the algorithm decide for me, I wouldn't have gone to Iran.

Similarly, there are a lot of things that wouldn't seem like an "option" to a computer but are an option to me. I've wanted to see Greenland from the air, so I've been taking a lot of flights that pass over Greenland on the way to places I needed to go anyway. But if the algorithm decided for me, it would probably have booked air tours over Greenland - substantially more expensive in terms of both time and money. It wouldn't be able to say "hey, you know that trip across the Atlantic you have in a few weeks? Why not pay $25 more to have it fly over Greenland?"

I've noticed that problem in my life as well. As a result, I decided to consume media a bit more randomly. My harddrive has a folder called "todo". This folder contains subfolders labeled "watch", "listen" (which includes "music" and "podcasts"), "read" and (a fun one) "pilates".The folder "watch" includes mostly movies and documentaries, sourced from my public service broadcaster's VOD service (which I scan weekly for interesting stuff) or youtube. The "music" subfolder of "listen" contains first and foremost dj mixes I've collected from eclectic rss feeds."read" has all kinds of PDFs and HTML pages (mostly scientific papers, long-winded articles and e-books). The "pilates"-folder contains videos of individual exercises (I find it more exciting to not always do the exact same routine)

On top of that I've written a script which prompts me to choose a category (i.e. one of the folders delineated above). It then randomly opens a file from the respective directory. When I am done using a file the script asks me whether I'd like to archive it, keep it (in case I am not done with it yet) or delete it.

I love the idea of random surprises.

I created a simple app that picks random items from a Chinese ecommerce site within a set budget. My long term goal was to use ML to learn what each user liked and send them random items on a schedule, selecting from multiple sites.

I never finished it because other things took precedence but the random selection part works.

Anyone interested in this as a service?

I'm not a developer but I did once build a prototype that sent text message inquiries throughout the day (within hours configured as "open" on my calendar). The questions were customized around a few goal areas, as a way to measure my progress. I never found much support for it, but the concept was intended to give techies with the hyperactive schedul tools a chance to leave "generic" hours on the calendar while still being accountable to being productive during those times.

Tried a similar idea with a diet-specific set of goals. Aiming for 100% comprehensive tracking of your calories seems a bit crazy to me.

you don't need an app to do that though. a spreadsheet is perfect for that purpose (and telling Google Assistant to 'flip a coin' or 'give me a random number between 1 and 20') and gives unlimited flexibility and less reliance on developer to implement features you want. not a lot of people appreciate this, but sometimes trying to accomplish a task with the general-purpose tools you have at hand can lead you to discover solutions so good it is in fact superior to any dedicated tool.

Your solutions in detecting Chrome headless is good.

But someone who really wants to do web scraping or anything similar will use a real browser like Firefox or Chrome run it through xvfb and control it using webdriver and maybe expose it through an API. I find these to be almost undetectable.. The only way you can mitigate this is to do more interesting mitigation techniques. Liie IP detection, Captchas, etc.

edit: when I say real browser, I mean running the full browser process including extensions etc.

You can just use document.body.

I also suggest to use a data URL instead. E.g. "data:," is an empty plain text file, which, as you can imagine, won't be interpreted as a valid image.

 let image = new Image(); image.onerror = () => { console.log(image.width); // 0 -> headless }; document.body.appendChild(image); image.src = 'data:,';
> In case of a vanilla Chrome, the image has a width and height that depends on the zoom of the browser

dumb question from someone who's written a ton of scrapers and scraping based "products" for fun:

at what point does it make more sense for companies to just start offering open APIs or data exports? Obviously it would never make sense for a company who's value IS their data, but for retail platforms, auction sites, forum platforms, etc... that have a scraper problem, it seems like just providing their useful data through a more controlled, and optimized, avenue could be worth it.

The answer is probably "never", it's just something that comes to mind sometimes.

Let's say this is about the Google memo. And let's say, for the sake of argument, you're a person who thinks Damore had some good points and some bad points but you think the hysterically censorious response to him was way over the line. But you don't want to become a pariah yourself, so you stay quiet about it. The argument Damore was making was fiddly, kind of subtle and takes a long time to explain, it's not worth the trouble you're going to get into. You take the Kolmogorov option and decide to wait out this insane time period.

Only it turns out, when you don't decide to argue for that subtle and qualified defense of Damore, a bunch of alt-right internet trolls make some terrible fallacious defenses of things he didn't say. Suddenly, the original censorious instincts seem much more righteous and justified. After all, "Now there are only full-throated red-pillers arguing in Damore's defense! We were right all along!"

Now there are two sides to this issue, and they're both identity politics and brain-dead shouting. Because no one stopped and offered a third option: actually discussing his argument, acknowledging where he was right, and discussing what he got wrong.

Besides ideological self-righteousness, Aaronson left out one important component of oppressive regimes, which I think is actually far more important: it takes a relatively large amount of people to topple a regime, while small groups as well as individuals do nothing but expose themselves by rebelling. So no individual with any regard for his own personal safety has any incentive to rebel, and will instead go along with the flow for as long as it's tolerable to him.

But this, on the other hand, would create an odd situation where actually the vast majority of people might actually wish for rebellion, but none of them actually acts out on that wish. Which I also think is actually much more likelier than what he's putting forward. True crusaders are rare, most of people are "just following orders".

A bit of game theory might be useful - https://object.cato.org/sites/cato.org/files/serials/files/c...

Riots and revolutions are difficult to start because of a number of obstacles:

* It is not clear how many sympathizers you have.

* Even if you believe you have the numbers, being the first to act may result in you being made an example of by the authorities.

It's smarter then to rely on more ambiguous signals. Playing stupid is a good way to do this. The problem is, the people who want to "stick it to the man" are generally young people who still process emotions with their amygdala - they can't keep their ego in check and pretend they don't realize they are contradicting the official doctrine.

It's fun to think you can be like Martin Luther, nailing The 95 Theses to the church door. We only hear about Martin Luther because of a quite literal survivor bias. Also, Luther survived because he claimed to not be challenging the Vatican's authority, but simply having a scholarly debate. He was also quite lucky that the secular authorities were lenient (perhaps for political reasons - there were lessor nobles who weren't so keen on the Holy Roman Emperor's authority).

What I find myself wanting to fight is not the prevailing views on a topic, it's the willingness to lie and mislead to promote those views. I saw that this past week with the Google memo situation. I also saw a shocking amount of it last year with the US election. Sloppy journalism feeds the people who seem to want to believe the worst in everything, who in turn feed entire social networks. Eventually sufficient people have heard a thing that the network as a whole believes it. Individuals have little influence. I suppose public consciousness (and social media in particular) could be thought of as a big NN.

I don't know anything about Kolmogorov, so I can't evaluate the assumption that he obviously saw through the lies and was horrified by the brutality - but I will note that a great number of prominent intellectuals, who were in absolutely no private danger from the soviet regime whatever they'd believe and say, and who definitely had access to information about the brutality, who still chose to support and defend the regime.

Without evidence to the contrary, it's plausible that Kolmogorov simply supported his government and found the brutality to be acceptable collateral damage.

If we've learned anything from the 20th century, one thing should be the lesson that even very smart people can be found supporting extreme brutality in support of an ideology.

My only complaint is the 'truths everyone knows' but doesn't say. Most people just don't care. there are a few thousand people that think deeply about worldview A, and a handful of others that think deeply about worldview B. Everybody else is worried about milking their cow, or pilgrimage to the holy land, or picking the kids up from soccer practice.

When worldview A is dominant, problems are framed in terms of A. It's literally hard to have those 'hey, that's funny' moments. And when I do, it's easy to dismiss them. I haven't thought as deeply as the worldview A people, i'm probably forgetting some minor detail. Worldview B people are trained scientists, who spend years honing the 'hey that's funny' detector. I can't compete with that.

Maybe i'm weird. I don't think so. I've had my insights about programming problems, but there are so many topics where i'm simply ignorant. There are so many subjects where i'm a fish, i can't see the water.

The author brought up sexual orientation. I am not a human sexuality researcher. I don't care to be one. My information comes from the culture i live in. I was incredibly happy for friends that were able to marry. If i lived a hundred years ago, i strongly doubt i would hold that same view.

I agree with the author, because culture creates defaults. Push culture when you can. Make better defaults. Most people don't change the factory settings. They are lazy. Or busy. Or really just don't care.

Time and again, though, I'm disappointed by how reductive and unmeditative these discussions are. I'm also surprised by how angry people seem.

This is a site used by a lot of very smart people, but I think there is an element of people transferring the confidence of their domain expertise from one area into another, without noticing that they've crossed that border.

One problem with creating an island of reason in what is apparently a sea of chaos is that the values that are cherished: reason, truth, rationality and merit are quite possibly the very things the regime is trying to suppress - or at least use a fuel for their outrage in order to promote their views and desire to be seen and hear at the expense of everything else.

The problem I see here now is that the regime is much more distributed with no apparent central authority to work against, however quietly. Comparisons have been made with the Soviet Union, the Vatican and the Nazis but they were all based on an ideology. Social outrage, social signaling and self-righteousness are more fundamental characteristics of humans' group behaviour than politics and for that reason it will be much harder to oppose and even harder to change.

A more apt example might be the effort it took/will take to topple slavery - which despite the change won in the Americas still unhappily exists today in other forms. Other fundamental beliefs can be so deeply rooted in culture that they persist for many hundreds of years and change, even it if is superficial, can take a very long time.

Charles Murray's research exists. Brendan Eich is still rich. Richard Stallman has an extremely unpopular opinion about child porn on his website and he still does talks to people who worship the ground he walks on.

Tell me, truly, is this a view held by many here? That, as the church denounced Galileo's observation that we turn around the sun as heretical, so too our modern PC culture suppresses legitimate inquiry into wether gender is a determinant of programming aptitude? This is a comparison worth drawing?

Galileo was a scientist. He published papers, books, treatises. He devoted his life to the pursuit of the truth, found a big piece of it, and was punished by society for it. He is one of the giants whose shoulders we stand on.

Kolmogorov sounds cut of the same cloth. He built a research center, helped other scientists on the way up, and left a legacy.

James Damore is a junior programmer who wrote a 10 page 'manifesto' accusing his colleagues of having inferior genes. This created a textbook hostile work environment,[1] leading to his firing.

The amount of sympathy I've seen here is dismaying. It is illustrating just how far we have to go until equality is the rule of the day. Please, before you throw in your lot with him, consider how ridiculous the analogy OP made here is. The Google Manifesto is manifestly not A Dialogue Concerning the Two Chief World Systems.

The BitTorrent Protocol Specification v2 bittorrent.org
311 points by Nekit1234007  1 day ago   107 comments top 9
jzelinskie 1 day ago 5 replies      
This update to the spec is a modest change that's largely a preemptive reaction to SHA1 being broken; large portions of BitTorrent are designed around the 20-byte length of a SHA1 checksum. They've decided to move forward with SHA256 truncated to 20 bytes to avoid incompatibilities with existing infrastructure such as the Mainline DHT.

Beyond the hashing algorithm, some important additions that were previously proposals without widespread use (e.g. merkle tree for hashing pieces) are becoming required. The focus has mostly been on optimizing latency for the P2P protocol and making sane improvements to the file spec. I feel like trackers were largely overlooked in this update, but I'm biased because I work on a popular tracker.

Ideally, BitTorrent would be broken down into separate specifications that could be used together or in separate systems: one for the file format and piece representation for sharing files, one for the P2P protocol, and one for discovery (trackers, DHTs). I want to believe that there would be far more interesting P2P projects if you could just lift robust primitives from BitTorrent.

Scaevolus 1 day ago 4 replies      
1) Chunks don't span files. Each file is validated by the hash of its merkle tree. This is the biggest user-visible change, since it means you can download one file without downloading others.

2) SHA1 is replaced with SHA2-256 (2x longer hashes and not broken).

3) Files are represented by a tree structure instead of a list of dictionaries with paths-- this reduces duplication in deeply-nested hierarchies.

4) Backwards compatible-- you can make a .torrent file with both old and new pieces, and a swarm can speak either. This requires padding files from BEP47, which most clients probably don't support.

Per-file metadata increases pretty significantly, from ~19B (just length) to ~68B (length + hash).

I have to admit, BitTorrent is one of the things I took for granted.

I never really thought about the details of how it works, or the really really impressive feats that were accomplished to get it to work. I knew it was a really good technology, but reading this and the comments here puts it on a whole other level.

Why isn't this technology talked about more? Why are blockchains the big "thing" right now with people trying to use them everywhere to see where they fit best, but torrent networks are kind of just... ignored?

The decentralized nature of it seems to open so many possibilities at first glance, is there a reason they aren't being taken advantage of? Is there some kind of "great filter" kind of thing that is preventing widespread usage of something like a torrent network?

I just don't see this technology ever going mainstream. I first deployed this type of application in 2003. It was named Redswoosh and did effectively the same thing as BitTorrent, just in a closed client. I was also a very early adopter of BitTorrent using it personally.

Users hated it for general use, even when downloading big files. 1) They didn't like having to install/run some special software to download a file. 2) They didn't like the effects of uploading to others and it slowing down the connections.

Consumer networks are asymmetric having far more download capacity in upload capacity. This makes sense since 1) most users download and want to use the available bandwidth for faster downloads, and 2) it prevents commercial applications on consumer circuits. This is far from ideal for applications like BitTorrent.

I'm not saying there isn't an application for this technology, I'm saying all the good applications don't want to ask the users to pay for distribution to other users. Thus it's relegated to mostly piracy, open source, etc.

Bittorrent Inc. has been trying to commercialize this for a decade now, I just don't see it happening. If there was anyone who could commercialize it, it was Travis Kalnik, and while he exited for 20m, he was very lucky, (and happy) to get out of that market.

It's weird seeing this. In Australia prostitution is completely legal. There was actually a publicly listed brothel for a while. Strange to think other societies criminalise it.

I think being legal is best for the health and wellbeing of the sex workers and minimises the criminal involvement.

There are brothels all over the place but mostly they are pretty low key, often hidden in backstreets or warehouse areas with only a red light and a sign to indicate they exist.

I wish we had such an enlightened position on drugs, which remain almost completely criminalized, whilst other parts of the world move towards legalization of various aspects of drug law.

Either as a society we accept that some people will trade sexual favors for money or we refuse it. I can see arguments both ways. In the end, that is a stance on how you weight two values:

1. The morality to add financial consideration in the decision to provide consent to a sex act.

2. The amount of freewill that a person has within the job market.

What is interesting is that you can have different liberal or conservative position on both of these considerations and still be unsure about the side the scale weights in:

As a conservative:

1. Social conservatives tend to consider sex like a serious matter, set apart from the rest, so they will say that consent is not to be sold.

2. Fiscal conservatives tend to consider freewill in the job market is close to absolute: you are always free to refuse a job, so people deciding to go into prostitution really chose it without constraints.

Depending on how you weight sex-is-special vs job-market-is-free, you can be against or for prostitution as a conservative.

As a liberal:

1. Social liberals will tend to consider that consent is important in every part of life but that sex is (or can be chosen to be) an activity like any other. If someone is really willing to sell sexual favors, under what principle forbidding it? (and it turns to be a fetish too)

2. "Fiscal liberals" (is that an expression? Not sure, non-native here, I mean the opposite of "fiscal conservative) tend to consider wages and employment to be a tool of oppression and control. In that respect, they will be less likely to consider that someone who works for money chooses to do so freely.

Depending on how you weight you-are-free-to-sex-as-you-want vs wage-is-a-way-to-control you can be a liberal and be for or against prostitution.

3.) There is a problem with human trafficking that has to be dealt with. But dealing with this problem in some manner is surely the better way than making prostitution illegal. As long as there are hormons in this world, prostitution will exist. Learn to live with it.

Summary of results from prostitution decriminalization experiment:

* Female gonorrhea rates decreased 40%* Reported rape offenses decreased 30%* No evidence that decriminalization increases human trafficking

> She has a theory, though, in that while she knows for some men rape is about power, "I think the argument that we're making is that that might not be true for all men, and for some, these activities could be substitutes."

> In other words, for some men, rape may be just about sex. And if there's a legal and accessible market for it, the number of rapes in a community may go down. This has not been a popular theory or study. And for many, it challenges the notion that rape is about violence and power, and not sex. "So I consider myself a feminist, but I think this finding angers a lot of feminists," Shah said. "It is a very controversial idea."

What the hell is this "rape has nothing to do with sex" nonsense and why does challenging this absurd assertion anger feminists? How removed from reality do you have to be to believe that forcing sexual intercourse on someone has nothing to do with sexual attraction?

But back to the topic of criminalization, it's downright disingenuous to conflate prostitution with human trafficking. And I don't believe the government should be in the business of imposing its moral whims on the decisions of consenting adults.

Banning anything that has a high demand mainly gives criminals control of the market. It has little impact on demand but is an abrogation of any responsibility to regulate.

The same was true of the US 18th Amendment, of the "War on Drugs" in the US now, of the banning of sex work, or most anything else. When the government decides to just ban something, others step in to control the market without any rule of law or responsibility to the public.

TFA: Still, perhaps even more surprising than the decrease in gonorrhea was another public health development. Sexual violence, or rapes, dipped dramatically. And this wasn't just amongst sex workers. It was across the board, according to FBI crime reports and jurisdiction level data.

"Reported rape offenses decreased by about 30 percent," Shah said.

That's another big decrease. Shah says, if anything, you'd expect rape to go up as when prostitution is decriminalized, sex workers are more likely to report rapes. She compared this to neighboring states, too. The drop was only in Rhode Island. So she examined other crime data in Rhode Island, like burglaries and murders, to see if there had just been a drop in crime generally.

It didn't match.

Saying "takes aim at the demand" for a mutually consenting interaction just seems a way of targeting men without explicitly saying it. Different countries and situations, but the reporter doesn't note the different treatment by the state when one sex is criminalized versus the other.


> "You see the silencing of victims," Hughes said. "It is just very harmful to women. It really is a libertarian approach, but the ones who get freedom are the pimps, the sex buyers, the businessmen who then can rent properties to the massage parlors, and to the sex buyers. There's very little freedom for the women."

Nothing wrong with a woman's perspective, but men's behavior was criminalized too. I would think it would add to the article to get some of their perspective.

Not including men's perspective, except as the businessmen who make money off the women and the rapists, makes the article sound like the reason for prostitution's negative reputation is men. Would a quote like the following fly?

> "Criminalization is a punishment for men who won't conform. We're just supposed to go live without sex and not complain about it, and be good men."

It's legal in Germany too.

My girlfriend grew up in a red light district.

She said it was mostly okay, the nights were a bit rough, because the clients would often argue loudly with the girls right before her window.

But the "madame" of a brothel around the corner would always look after the children going to school in the morning so they wouldn't be bothered.

As someone from a country where all form of prostitution is legal and regulated it did not really ever come up as something odd when I grew up. Prostitution is becoming less prominent in recent years because families move into places traditionally frequented by prostitutes but the industry is healthy as ever as far as I can see.

Do you guys think that the majority of sex workers really enjoy their work or prefer it? Do you think that this is the career they prefer? Do you think it may have some affect on their psychological well-being?

I believe prostitution is an indication of a lack economic and social well-being both in the case of buyers and sellers.

Within about one or two decades maximum there will be revolutionary advances in robotics including things like much better weight-to power ratio artificial muscles and increased bio-mimicry. This will lead to truly life-like sex robots. Along the same lines, the majority of "ordinary" jobs that humans can currently do without high-bandwidth connections to computers or control over them will be replaced with sophisticated AIs and robots or automation. The perspective on sex work and general objectification of women will shift more towards one side then.

I think the best way to handle prostitution and recreational drugs is to let each neighborhood decide what is allowed. If the majority of residents and majority of property owners are okay with a particular activity, it should be legal there.

There are always going to be problems allowing these activities and problems with banning them. If you let each neighborhood decide, at least you're moving the problem to areas that are ready and willing to deal with the problems. They can tax it, regulate it, provide security, drug treatment etc. That means the neighborhood has to form some kind of legal entity, of course.

And you're giving the customers reasons to go where they are welcome. By doing it on a neighborhood level, it becomes much easier to comply. It's easier to drive 15 blocks than to go to the next county.

And I think enforcement where it is banned can just be done with fines, giving people a good reason to take their business to where it is welcome. There's no reason to put people in prison.

You should also read part 2 of the article.

After some relationships from 18-28 that all ended unhappy, I decided to screen my next partner in a very rational way. Of course I wanted romance and some attractiveness out of my next girlfriend, but I primarily wanted a friend that I could talk to when we were 95 and sitting in wheelchairs next to each other, unable to do much else. Destiny called and the girl I then met and found worthwhile to date further became my wife and mother of two children.

Why I reference the second part of the article: we just talked about it and totally agreed that our marriage was more or less how it should be (as described in part 2) and felt not at all touched by part 1.

While we are for sure people that are different, we usually find new stuff we absolutely want to do together. Last year we did boat- and radio licenses (5 so far...), this year we began pistol shooting in a sports club, we travel to many places, have tons of family meetings (I think being in a supportive family helps a lot, too)... yes we also have the occasional fight, but there has been exactly no occurence where it had not been completely resolved before sleeping.

So being rational about your partner does not mean to stop the fun, stop the romance, but means you know exactly what you get into and care for the happiness for you own life.

Remember: a divorce is often the complete destruction of your life dreams. You can destroy yourself and/or your partner. Your partner REALLY gives the single life he/she has in your hands and hopes, like you do, that everything will go right. Don't be a fool when given such a treasure.

1. I have always hated the notion that having a happy marriage is about filtering through many candidates to find the one perfect partner. Although I do think it's reasonable to try to learn early on what you're looking for, this idea that we should all be dramatically expanding our dating pool to find the perfect person is abominable.

Look at a city with a massive population of eligible young people, like say NYC.. and then listen to what people in NYC say about the dating scene there. It's not pretty. Having such a huge pool of potential mates discourages people from committing. In other words, it makes it harder to find a long term mate, and it makes you less satisfied with whoever you're seeing.

2. Biology isn't the only reason a person might want to get married before 40. There's something to be said for sharing your early adulthood with a person. Meeting your life partner at 37 will be a very different experience from meeting your life partner at 22. Not necessarily a bad experience, but not what everyone is looking for.

I like the way this article flips the commonplace 'What are the criteria for selecting my perfect mate?' to 'What are my motivations for getting married?'.

However, it needs to be said that if and when children arrive on the scene, everything changes. So really, in my opinion, the predominant issue is 'Do I want to have children and how do I want them to be raised?'

What I always tell people who are dating, and only half joking, is you need to find someone you can be bored with.

When you're young and just done with education, starting work, things are changing quickly. You're getting a lot of new experiences and meeting new people. It can be very exciting.

Unfortunately, it's unlikely to continue like that. You can't always be travelling, changing jobs, or even go out on the town. This is primarily if you're going to have kids. They need a routine, which means you need a routine.

So the challenge is to do the exciting dating thing while looking for someone who will be happy with something much more monotonous. I met at least a couple of women who seemed likeable but just didn't act like they were going to be happy on the long straight.

Marriage, monogamy, and (romantic) love are conservative notions that are close to being (or should be) marginalized in my opinion.

Romantic love, especially, is an extremely superficial and hollow idea exalted to high heavens by the group-think of the masses. I gave up religion, and over the years realized that love is the second, way more sneaky and no less damaging, delusion that humanity indulges in. It has to go the way of the religion.

I hope most of you would agree that at least 70%-90% of being in love has something to do with the appearance of your person-of-interest (most of it visual). No matter how you cut it, no matter how much of an intellectual you are and how much you prefer to connect deeply with a person, in the end, given two individuals, you fall in love with the one that is more visually attractive. What a coincidence!

And what is visual attraction? In other words why do we find some people more beautiful than others? Because we have a biologically ingrained form of discrimination based on looks. It's lookism plain and simple.

Note that I do not buy the silly notion that 'beauty is in the eye of the beholder' and that 'I don't find that person attractive but I'm sure someone else will'. This is somewhat backed by data (e.g., the OKCupid survey), but I have developed this belief on my own. Humans of all races have a built-in instinct to find some visuals more appealing and attractive than others. It is sad but true. To take it to an extreme, if we find some visuals disgusting (e.g., spilled guts, slimy things) we don't all of a sudden go "I'm disgusted by slimy spilled guts of animals, but that's just me, I'm sure there are plenty of people out there who have the exact opposite reaction, that they love to look at slimy spilled guts".

What I'm trying to say is that standards of visual attraction, while not physically objective, are largely biology objective, and yet, it's a bad thing, because it's a symptom of biological imperfection. It's a genetic defect in our biology and 99.99% of humans are afflicted by it.

I personally think social individualism is a concept that needs to gain traction in modern society. It is the 'atheism of love'.

I very much enjoyed Part 2 of this article. It puts forward a much more complete framework for success than part one, which mostly just talks about the flaws in many standard approaches.

The notion that you are going to find the perfect person for the rest of your life at any given moment in time is ridiculous - you are going to change, they are going to change, your relationship is going to change both of you. The sense of friendship, being at home with one another, and the mindset that a marriage takes work have all been instrumental in my own marriage so far.

My wife and I met in our early 20s. The things we wanted out of life - both individually and as a couple - have changed significantly over the past decade. It is likely that if either of us had known where we would end up we might not have chosen our past selves to be together with our future selves. However, we've been a part of every individual and collective change and have worked to build a strong relationship through the changes. There is something amazing about walking through adulthood together and staying committed through all of the ups and downs.

This was a very insightful read for me, where I introspected and identified a lot of things I had done wrong myself in relationships. That said, it was also kind of depressing. It seems that one of the greatest unsolved challenges of life is efficient matchmaking, and despite all the technology poured into it we are nowhere close to having a good solution.

Swipe-apps (latest generation of matchmaking) are completely shallow and almost entirely based on appearance and no other factors which leads them to be used for either hookups or entertainment.

Profile-based apps lead to box-checking behaviors, incentivizing people to look for "scan-tron partners" as the article calls its.

Personalized matchmaking services are expensive, time-consuming, and are limited to the pool of people willing to invest that amount of time and spend that amount of money, which is not that many folks.

This is one problem area I'd love to see some new startups address in a serious manner.

Finding the right life partner requires a series of filters. For me, those filters were: 1) quality of conversation; 2) ability to share work; 3) trust and reliability; 4) physical attraction. Not necessarily in that order, but long-term, the conversation and ability to collaborate with someone on the joint project of a household or family are way up there in what to look for. You definitely talk and work with each other a lot more than you moon and snuggle, so you should find someone you like to talk and work with if you want to like your life. It's really hard, though, because when you're attracted to someone physically or just desperate for sex it's a lot easier to fool yourself into thinking that their conversation is really interesting, when in fact you're just high on pheromones.

>everyone looking for a life partner should be doing a lot of online dating, speed dating, and other systems created to broaden the candidate pool in an intelligent way.

Anyone ever heard of the paradox of choice?

All of the research I've read hints at relationships that start with a dating website being being much more fragile than relationships that have met more traditional ways and much more likely to end with a bad outcome.



One may argue this is good that we are ending "bad" or "not perfect" relationships... the other side of the coin is online dating may not be leading us astray from actually meeting someone we are compatible with and is just a distraction or worse, it may be making us bad at relationships once we met someone.

It was surprisingly hard to figure out the problem with these two articles.I mean it all makes sense, I couldn't stop nodding. And dont get me started with the picture from the stairs where the fighting couple stands below the lamentable single person. I mean: yes! And if that is not enough, our reading efforts are rewarded with a handy checklist for choosing the right partner.

I know the author might not happy about this, but I have an odd feeling (ha, shoot me). And the intensions they where, as they always are , the intentions where good. Nobody was hurt, no potential was spoiled, no time was lost. Everyone is happy. Sure there are conflicts and stumbling blocks, but with solid work and communication you disolve them into harmless bumps while sailing away on your Loveboat. Ready for the next chapture. Buying a house. Having kids. Growing older together. Die with a smile on your face surrounded by caring people.

If anything is overly romantic, than this. Completely ignoring the context you live in and reduce everything to a handfull of personal traits and skills is overly simplicistic (stupid) and naive, because:

- you cannot create love by communication, or transform friendship or nice feeling into love

- It is reasonable if you seek for true love and believe in fate (But only until you're 30)

- If you have been hurt, betrayed, used and left, take it as a sign to loath yourself less (and not others more)

- Life can be bitter. Love can vanish. Dreams can be shattered.

There is this song "Hello" from Adele, which is fairly popular. It describes somehow a state of love and connection after it is long gone. Something I'm not sure this author would even understand.

graycat 1 day ago 0 replies      
What I saw in my own romantic relationships and those of others was a simple, blunt point: Do both of the people actually want to follow the first part of the standard marriage ceremony?

"We gather together to join this man and this woman with the bonds of holy matrimony."

Instead, one or the other didn't really want to "join" or "bond" and, instead, was just using, exploiting themarriage and spouse for some selfish aims.

For women, the main use was money -- she wanted to be supported. That was as far as she thought. Later one had one child, retired to a back bedroom, lived on chocolates, gained 150 pounds, and vegetated. Another had one daughter and later one by accident, retired to a back bedroom and lived on cigarettes and beer. One decided to become really good BFFs with Jim Beam and Jack Daniels. One really wanted just to do social climbing at the most expensive country club in town. Another wife wanted the spouse's wealthy family to fund a retail startup. When the startup failed, she went to college, then art school, then became a leading horse woman, all with no interest in her husband, and finally just moved out. She was very pretty, moved to NYC, apparently to try to make a big splash in media. Never heard from her again!

One husband liked sex with men as much or more than with his wife (at least two cases of that, with both of the wives very desirable); the wives didn't like that situation.

Another wife just wanted her husband to put her through law school at which time she planned to leave the marriage. Another wife just wanted her husband to put her through graduate school, at which time she planned to leave. Another wife wanted to use the marriage as a home base for various projects, around the world, to save the world.

I saw a lot of such problems: It was simple: One or both of the spouses failed right at the first sentence of the marriage ceremony -- they just didn't want to join or bond. Just didn't. To them the marriage ceremony was just a costume party with nothing serious and no connection with reality, and they wanted the marriage not to join or bond with their spouse but just to exploit them.

So, from this theme and these examples, what is in the OP is too complicated and misses the point: The point is, both spouses have to be serious all the way through the marriage vows, and failing right at the first sentence is really simple, much simpler than the OP, way too common, and a guaranteed disaster.

> But good old society frowns upon that, and people are often still timid to say they met their spouse on a dating site. The respectable way to meet a life partner is by dumb luck, by bumping into them randomly or being introduced to them from within your little pool.

Well, yeah. This is how social networks work: similar people group together, people socialize within that group, and they match with people who they are similar to or find ideal. They don't need to search for a partner because their ideal partner is already somewhere within their social network.

People with poor social networking skills will not "bump into" potential partners because their network is poor. It's like expecting to find an investor for your startup if all you do is post to "Show HN". You might have to actually leave your forum, or computer.

And so, after eliminating all choices from one's existing in-person social network, people with bad social networking skills look for dates on the internet. This is an uncomfortable yet common-sense truth: much like marrying your cousin, there is a stigma for a reason.

There is currently no online service that can correctly predict if someone will enjoy your physical presence. You can check however many boxes you like and you will still end up being weird. This is perhaps one of the biggest reasons that there is a stigma against online dating: usually it does not work out. If online dating really worked you would only have to go on three dates before you met a perfect partner [that was also geographically and socially convenient to date]. But it turns out that online services are just another poor social network.


Aside from that probably-going-to-get-me-downvoted-to-hell-unpopular opinion: the author presents one view of how to pick your life partner, from one way of life. Depending on where you live, your personal values, your preferences, your goals, etc your ideal partner may look quite a bit different than the author describes.

Humans change over time. Your ideal partner right now may end up being a completely different person in 10 years. You can either accept this, or accept that your life partner is simply a "current partner" and that, similar to all other kinds of partnerships, it may not last forever.

The author is also conflating life partnership with marriage. Traditional marriage is a generally horrible custom that developed around the idea that one partner didn't have as much agency as another, and that the partnership is necessary so that the oppressed individual can retain some form of protection, usually in exchange for sexual or other reciprocation, and the relationship is almost always exclusive (for the oppressed partner).

You may want a life partner, but don't want to get married. This is increasingly the norm in modern western society (whereas before it might have landed you in jail or dead). You may want more than one partner, or your partner does. Non-monogamous relationships are becoming more common and better understood by the general public.

I'm not an expert, so I can't tell anyone how to pick a life partner. All I know is that to understand what you want in someone else, first you have to know what you like and don't like, for yourself as well as in others. Then you need to be able to express that coherently and immediately, without shame, regret, or miscommunication. Knowing how to do that will help you to search for and identify a potential life partner. But remember that it may not fall within the normal accepted standards of society, and you have to accept that, or you may indeed fall into the same trap that so many others have when they rely on a universal measuring stick to find the right fit. And above all, I think that if you can't find what you're looking for in your social network, you need to expand your social network - and not just via dating sites.

I like this pricing model compared to udacity's new nanodegrees. This works better for people who want to rush through the course as quickly as possible. It essentially encourages faster completion.

You pay $49 per month and finish at your own pace. On Udacity you pay a fixed price of approximately $800 per semester with a trial period of 7 days. Since you are paying for the entire course upfront, you might realize after a few weeks that you don't like it. On Coursera, you can stop anytime and you've only paid $49 x number of months you tried.

After having taken Udacity's ND, the only way I would consider taking this course is if they go in-depth with the theory so that I can clear interviews and work on projects from scratch. There's just too many resources for DL now. It's getting ridiculous. Had Udacity gone in better details with their ND I would glady have paid double for them.

Coursera does not having proper support systems like good quality forums/any mentorship/project reviews. Although, been a while since I took a Coursera specialization, would rate Udacity higher on that front even though their ND was too basic (I can't even talk about what I did in a project clearly because of so much lack of stuff).

The article hides a common but incorrect assumption. Look at this paragraph:

> As mentioned in the memo, gendered interests are predicted by exposure to prenatal testosterone higher levels are associated with a preference for mechanically interesting things and occupations in adulthood. Lower levels are associated with a preference for people-oriented activities and occupations. This is why STEM (science, technology, engineering and mathematics) fields tend to be dominated by men.

The assumption here is that employment in STEM industries fundamentally and solely involves "mechanically interesting things".

The reality is that tech companies are composed of people and make products for people. Google themselves have found through their own research that the best managers are defined by their people skills, not their technical skills. So why aren't the management layers of tech companies composed of mostly women?

Strong technology is important for success, but so is leadership, market fit, team dynamics, understanding the customer, etc. The hardest question in tech companies is not "how" to build, but "what" to build. This is essentially a people-oriented problem, since customers are people.

I am always surprised that well educated people who are definitely not "creationists" but consider evolution as a way human kind developed are ready to ignore evolution when it comes to gender.

Clearly man and woman are different physically and mentally as for millenias they played different roles. Why "gender people" keep ignoring that and are claiming that sex is not something inborn and is a "cultural" phenomena is hard to understand.

For me gender studies are just new incarnation of Lysenkoism. Lysenko strongly belived (and thousands of soviet scientist) that weeds could spontaneously evolve into food grains because is should cooperate with communistic party.

Those who were against that obvious stupidity and claimed that genetics is the way to understand plant evolution were fired or put to jail or executed.

What I find interesting about all this is how many people take personal offense from statistics. (and conclusions drawn from statistics)

The author seems to put an effort into explaining statistical distribution and what it means and what not. He's explicit that statistical observations can't be used to judge particular individuals. Draws a graph of overlapping distributions to drive the point home even more.

I'm not sure why would anyone get offended by statistical observation. It's not personal by definition.

> But sexism isnt the result of knowing facts; its the result of what people choose to do with them.

We know that men are taller than women. I can see you agreeing, but actually this statement is ambiguous, because these two are not the same thing:

 A man is taller than a women On average, men are taller than women
Sexism is taking a random male and a random female, and claiming that despite all the facts presented to you, the male is taller than the female. It doesn't matter that in a specific case a female is taller than a male.

The same can be applied to any group and their respective stereotype. The *ism happens when we fail to assess an individual on the data given to us, preferring to fall back on mentally-lazy stereotypes/generalisations even when what we can see says something different.

 A single study, published in 2015, did claim that male and female brains existed along a mosaic and that it isnt possible to differentiate them by sex, but this has been refuted by four yes, four academic studies since. This includes a study that analyzed the exact same brain data from the original study and found that the sex of a given brain could be correctly identified with 69-per-cent to 77-per-cent accuracy.
Well I'd argue that isn't great accuracy as 50% is what you'd expect from chance (though I haven't read those references). In fact, I might expect a similar accuracy from a machine-learning technique to predict sex based on your height.

I haven't touched on the causes of population differences. With height, I don't think anyone thinks it's anything other than genetic (by way of testosterone levels). For interests and skills, the proportion that is caused by testosterone versus culture/environment is still unclear.

If we believe there is still a cultural effect, then I think positive discrimination is justified to counter this.

As an anecdote, we were wondering why our four-year old son suddenly lost interest in 'Frozen'. He told us this week that a girl had told him at nursery that 'Frozen' wasn't for boys. Cultural stereotype reinforcement is alive and well, and starts early!

From below (I wanted to make sure this didn't get hidden under a downvoted comment):

>I fail to understand how a memo calling for MORE diversity can get headlined as "anti-diversity memo" on all big media outlets. Do journalists even do independent research anymore or are they just regurgitating whatever reuters send their way without scrutiny?

The author is referring to psychological diversity, in other words, Google should be more receptive to diverse viewpoints. This is both true and not true. Yes, we should listen to others and understand, but that does not mean we should accept and value everyone's viewpoints. To invoke Goodwin's Law, perhaps we should be more sympathetic to the viewpoints of Nazis? How about white supremacists?

There are viewpoints that do harm people within society, and this is one of them. Strip this down, this is the basic "woman's nature" argument that was used for years in the past to keep women barefoot and in the kitchen. The underlying claim that women are bad at tech is ridiculous. As mentioned below, the early programmers and data entry workers were women as it was considered "office work". I'll also throw out names like Grace Hopper and Ada Lovelace. Read a site like Godel's Lost Letter, and Lipton always points out women who have made contributions to the field. I even recall an article about a house wife who researched new fractals. Women have been engaged in science, technology, engineering, and math (and medicine) since the beginning. They were male dominated because people held the viewpoint the author does, which is essentially, "It's not a woman' place". Bullshit, plain and simple. This memo does not call for more diversity. It may cite scientific research (yes, men and women are different physically and psychologically), but it calls for the same status quo that initiatives like the ones the author lambasts are trying to overcome. Are they perfect? No. but they are a step in the right direction. We need to understand these difference and adapt to them not use those differences as a way to exclude.

I think science is a bit hyperbolic a term for this fiasco. More like mere statistics at best and we know how statistics can work out.

Calling psychology or psychiatry a science is a generous proclamation. None of the above practitioners, including a neuroscientist, neurologist, or a cognitive scientist, can explain completely why someone can look at a shot of whiskey, know it is an expensive whiskey, know how to balance the shot to their lips, then prepare for the burn, and then swallow it while hoping they will get "lucky" tonight but feel lousy tomorrow all at the same time.

We're not there yet when it comes to classifying humanity into "phylums" or categories via science.

This is obvious and not the point of contention. The crux of the other side's disagreement is in the assumption that differences in brain chemistry attributable to sex necessarily account for all or the majority of the differences we observe in career distributions. I think the insane reaction to this memo is unfortunate because the author does appear to make an earnest effort to discuss this topic, but the memo's defenders are not doing the argument any favors by arguing against the weakest version of the opposing argument.

As mentioned in the memo, gendered interests are predicted by exposure to prenatal testosterone higher levels are associated with a preference for mechanically interesting things and occupations in adulthood. Lower levels are associated with a preference for people-oriented activities and occupations. This is why STEM (science, technology, engineering and mathematics) fields tend to be dominated by men.

And why we see fields like law being dominated by women, right?

EDIT: I, and I suspect most other scientists wouldn't disagree that there are [edit - had this as aren't previously, woops!] physiological differences between men and women, but as I read the memo, that was not what was being argued. What was being argued was that those differences were the reason for the gender imbalance in tech (i.e. women are predisposition to be less interested/capable in STEM fields), in other words, the effect size associated with biological sex is larger (and indeed must be significantly larger) than any/all combined societal/'nurture' effects.

Would people consider it sexist to administer a completely automated test of technical and personality questions which was used by an unbiased program to hire only the best qualified candidates?

What would you say if the results were essentially the same as the status quo?

By the Article's Author's account, she believes that we would probably maintain the status quo with such a test, because she thinks people are self-selecting out of STEM. Others seem to think that there is some other barrier to entering -- would a test like this fix the issue, or is there something else going on?

This defense of the "manifesto" is flawed just like the others. It picks out a small subset of the claims made in the document, discards the context and all the other claims, and then harangues us for having a problem with "science".

We can talk straightforwardly about what makes the document problematic: whatever the validity of the "scientific" claims it makes about gender differences, there is no support (and likely no validity) to the connections it then makes to software development work. Despite that unjustified leap, the document goes on to suggest strongly that women working at Google are less qualified than men. There is no science Debrah Soh can cite to back up that assertion, however much she might want to.

Anyone can wrap an incendiary statement up in a pile of banal sentiment and ambiguous appeals to social science. When challenged, refocus the debate on the truisms and the footnotes and pretend you didn't write the nasty stuff you hid in the middle. And, as we can see, plenty of very smart people will fall for the trick.

Gender equity has been improving in the United States for several generations. As that has occurred, female participation in STEM fields (and in the professions, like medicine and law) has expanded dramatically. Many science fields are now approaching parity. Most have more than twice as much participation as computer science. That includes the field of mathematics, which is closely related to computer science and is certainly more intellectually challenging than "computer science" as practiced in the industry.

Among all STEM fields, computer science is distinguished for losing the participation of women over the last 10 years.

Unless the women of 1950 are somehow biologically different from those of 2017, the author's theory will somehow have to address the fact that her argument would have predicted the fields or law, medicine, biochem, mathematics, astronomy, statistics, accounting, and actuary would all be bereft of women over the 20th century --- obviously, the opposite occurred, despite the sexual revolution that was immediately to come.

The author of this article discusses a correlation between increasing gender equity and decreased STEM participation that does not appear in the evidence. There's a reason she does that: if you don't stipulate that correlation, the argument against gender bias in computer science has to confront another damning fact, which is that gender disparity in the field isn't global. Unless women in Asia are somehow biologically different than those of the US, her argument needs some way to address the fact that women make up the majority of STEM majors in many of those cultures.

Reading this article and then this thread, I find that there's really only two aspects of it that HN finds persuasive: the headline's appeal to "science", and the footnote observing that the author is a female scientist. That's not enough. Everything in between those things is wildly off.

In discussions about gender parity in CS, the word "preference" is a coded appeal to the Just World Hypothesis. There is a yawning chasm between neuroscience findings about "agreeableness" and "stress tolerance" and suitability for any particular kind of white-collar symbol-manipulation work. Ms. Soh must intuitively understand that, but mentions it not once in her piece, instead pretending that observations about the kinds of toys children play with allow us to reflect participation statistics directly into real preferences about work. Shenanigans.

This article would be a lot more worthy of a discussion if it actually discussed the actual issues.

How much is nature vs. nurture? (many of the behaviours the manifesto attributed to genetics are actually purely environmental)

Should that even matter? Shouldn't hiring processes be purely meritocratic?

The fact that the author of the memo argued for affirmative action for hiring more conservatives shows that he doesn't have anything against discrimination, as long as he profits. If he wanted a science-backed solution, he'd have supported motions to remove the topic of gender, race, political affiliation entirely from the hiring process. (Anonymous job applications can help with that).

Many of the sources were also quite misleading, or links to blogs instead of papers. The memo wouldn't pass peer review at any journal, and can, frankly said, not be called science.

As we also just had a big discussion about this topic on HN, this article is misleading and from an outlet that previously has published hit pieces on diversity policies[1], I flagged it - this discussion belongs into the recent megathread, not as its own onto the frontpage again.

Cycling can reduce risk of death by 41%, death by cancer 45% and death from heart disease by 46% http://www.bbc.co.uk/news/health-39641122

A single 10ft cycle track can carry the same number of people as 7 lanes of car traffic.

Netherlands is currently at 10% obesity and going down to 8.5% by 2030. The UK is at 27% and predicted to go up to 35%.

So cycling really does appear be to that miracle solution for urban transport but you absolutely cannot 'share space'. Absolutely key to segregate. A good end to end network is only as good as its weakest link and too many times, town planners give in to politicians and local residents and deliver stuff that really is does not provide inclusive ages 8-80 cycle routes.

Come to Amsterdam to see first hand proof of this study. Virtually no one wears helmets... because you don't have to. Infrastructure is designed to be bikers first. Drivers are constantly aware of bikes and also receive training to avoid the most common accidents (hitting a biker when opening the door - see the Dutch Reach).

The biggest threat to a biker in this city is another (often less experienced) biker, pedestrians not looking around or trying to cross tram tracks parallel. However, it did take almost 40 years to get here though, changes starting in the 1970s - I do hope many cities will follow a similar route.

u801e 3 days ago 0 replies      
I think a lot of the problems that cyclists have when riding amongst motor vehicles have to do with existing laws (such as riding as far right as practicable when going less than the normal speed of traffic).

In reality, most traffic lanes are not wide enough for a cyclist and a car to travel side by side with sufficient clearance between the two vehicles. A cyclist is about 2.5 to 3 feet wide and many states have laws requiring at least feet of distance between them and the cyclist. The cyclist will also ride about 2 to 3 feet from the right edge of the lane. A car is a little less than 6 feet wide on average.

If you add those distances up, you end up with a total of 14 to 15 feet. Even on interstate highways, lanes may only 12 feet wide. On surface streets, they may only be 10 feet wide. Because of this, you end up with the situation where cars will "lane split" while passing a cyclist and frequently misjudge how far they are from the cyclist when passing them. Also, the lane splitting car cannot leave enough room for cars in the adjacent lane because the lanes do not have sufficient width to accommodate a vehicle and half of another vehicle.

Another problem is that cyclists riding to the right aren't as visible to traffic as opposed to those who are "taking the lane". They're more vulnerable to collisions such as "right-hooks", traffic entering from side streets and opposing left turning traffic who didn't see them.

The laws should be changed to say that cyclists are like slow moving vehicles who are entitled to the full use of the lane they're riding in and passing traffic must move completely into the adjacent lane, when safe to do so, to pass the cyclist and only return to their original lane of travel after they have sufficient clearance. The law should also allow vehicles to pass cyclists on a double-yellow when its safe to do so with the same conditions as above.

This will legally sanction the "take the lane" type of riding and make cyclists more visible to the rest of traffic.

You mean less dangerous. To me, San Diego and Ft. Worth are average areas. In these places bicycles are relatively rare compared to cars. I am always surprised when I see them.

Cars weigh thousands of pounds. Consider the safety precautions for cars with air bags, crumple zones, and crash testing. There is no protection from cars for someone on a bicycle.

They try to say riding on the sidewalk with a bike is more dangerous because cars do not look out for bicycles at driveways and such.

But personally in most areas I don't feel safe biking on the street, and would rather stay on the sidewalk like I did when I was a kid. I would just have to pause to check before crossing driveways and intersections.

I believe that there will eventually be something like a smart safe city where 2000+ pounds vehicles do not freely mix with pedestrians, cyclists, and baby strollers. There should be physical barriers or totally separate walkways.

Think about it. They can't even sell a car without an airbag anymore. Yet what chance do you have from a physics standpoint to be truly safe when the other vehicle exceeds your mass by 2000+ pounds?

So my question is "why wouldn't this just rip in half from the forces it's under?"

The upward force for the 20m chimney is calculated at ~600 tons. 600 tons is not a lot for a building to support in the downward direction, but quite a bit for a fabric tube to support, in tension. It's the rope/(space) elevator problem - you need a super material to handle that much force, don't you?

But aside from worrying that our wacky inflatable tube of death will rip free from its tethers and tumble freely in the wind, killing thousands, I actually really like this idea, as geo-engineering. It is a process that can be stopped and started relatively cheaply, unlike a lot of other proposals. If the tube has unforseen effects, it could be deflated and reeled in, unlike eg throwing particulate into the upper atmosphere.

I get that the upwards wind force can sustain the fabric structure, but it is hard to imagine that it could also carry a bunch of huge turbines, as well as the cabling required to carry the generated electricity. Not to mention safety concerns. Does this seem unrealistic to anyone else?

Also, would it be possible to do a proof-of-concept using an existing man made structure like Burj Khalifa class skyscrapers? Presumably it would be easier to deploy a tube off the top of one of these than to build one from scratch.

If the column of air is really moving at 300 MPH, they'd better diffuse that at the bottom so people (and things) aren't sucked into the chimney (it would suck to be ejected at the top without a parachute but you could probably sell a ride to the top to the wing-suiters).

Engineering issues aside, to evaluate if a super chimney would be energetically viable you need to understand the concept of "Convective available potential energy" or CAPE--https://en.wikipedia.org/wiki/Convective_available_potential.... CAPE has dimensions of energy/mass and a describes how much energy is released by raising a mass of air to some higher elevation.

CAPE is used to forecast storm development, as updrafts can more likely spontaneously form when there is more energy released by the updraft. CAPE values can also be zero or negative, in which case there would be no available energy to sustain an updraft. From my understanding, CAPE is the only factor that would determine if a super chimney could work at a given time.

I have not found a good resource on global CAPE patterns including daily patterns, but it seems very likely that there is any fixed location and fixed elevation that always has a positive CAPE value. It would be an absolute requirement to find such a location for this project to work.

You should also be able to calculate a crude bound on the maximum updraft velocity simply as a conversion of potential energy to kinetic energy. Wikipedia says that exceptionally high CAPE values proceeding extreme thunderstorms are around 5kj/kg, which would accelerate a mass from rest to 100m/s (220mph). Of course this is an extreme value, typical values are more like 1kj/kg, which correspond to a velocity of 44m/s (100mph).

If this net force is stronger than gravity, then the air will experience upwards acceleration. This will continue as long as there is a difference strong enough. At the top of the tube, there is no more force since the density will be the same since the air will spread out after exiting. (If it's not already at the same density after going through the tube).

Looking at it this way this seems sound to me, am I wrong?

Presumably you just lay a pipe that goes up the side of Everest and free power!

I wonder if the author asked the question "Why don't we have tornadoes all the time?"

If they had, that would have lead them to the physics of tornadoes. In my case it was the physics of so called 'dust devils' in the desert which are much smaller phenomena but based on the same ideas. Warm air rising through cooler air.

You might ask, but why don't we have them all the time? And the answer is that as air goes up, it spreads out, and as it spreads out it becomes less dense, and the lack of density is perceived as a colder 'temperature' even though the air molecules still have more kinetic energy and are thus 'hotter'.

In the video the tube is supposed to constrain the air (which it will) and the warmer air will rise inside of it, but without an energy source the warm air rises until its 'weight' is equivalent to the un-risen air underneath it, at which point it stops rising and the system is stable. If you were to cool off the bottom the air would start sinking again.

This has been experienced time and again by inexperienced makers of fires in their fireplaces. If you don't put enough energy into the air to make it rise, it comes back down the chimney and fills your living space with smoke. A fireplace is a remarkable little machine, where the fire heats the air, which pulls in more air as the air above rises, which puts more oxygen into the fire and increases its energy output etc. But without the fire burning in the fireplace the air stops moving.

Tornadoes benefit from a mass of really cold air sitting on top of warm air. This does two things, one the cold air above pushes down on the warm air to pressurize it, and two when a "hole" begins forming in the cold air mass it operates like an inverted tub drain and the warm air starts draining out of the tub. The energy source for a tornado is the temperature differential that is set up by the result of moisture condensing out of the air and super cooling the air around it.

Similarly a hurricane is powered by the temperature differential between the ocean and the air above it.

All three systems (fireplace, tornado, hurricane) share a common theme, there has to be a source of energy for them to operate. Without it, the air reaches equilibrium and just sits there. No magic allowed.

That said, if instead you built a tunnel, then you could connect two different air masses and extract energy from two different pressure differentials. The most interesting ideas have a tunnel under the Rockies or under the Sierras between the Mojave desert on one side and the milder (and moister) climate on the other. To the delta you can get from that is linear with respect to distance and/or a geographic feature that can inhibit the natural balancing of the air masses (like a range of tall mountains).

Sadly neither super chimneys nor lighter than air vacuum balloons are workable ideas.

Edit: It occurs to me that if you could make the chimney high enough you could put the top in the underside of the jetstream, then you could suck air up using the venturi effect.

So many signals suggesting this is a wild physics-defying idea that could never work, e.g. how many websites claiming 'this one neat trick solves global warming' really hold the key to solving global warming?

I hope that's not the case and by this time next decade we're all laughing about that century and a half where we put so much carbon in the atmosphere wow wasn't that a hoot...

Realistically, I am sympathetic to the idea that geoengineering, massive structures and engineering projects enabled by modern materials, etc. deserve more thought.

scythe 4 days ago 0 replies      
These geoengineering proposals should be understood as mitigation strategies to be implemented after we have reduced carbon emissions, since even then we still have a problem. But this one seems very dubious.

>Speaking in terms of thermodynamic, we can say that chimney prevents adiabatic cooling of a rising parcel of air. Normally, when hot air freely rises in atmosphere, it expands as it gets higher and pushes the surrounding air. That causes surrounding air to heat and rising air to cool. That process continues until equilibrium is reached. At that point air stops its ascending. Unlike freely rising parcel of air, the air in the chimney is restricted in its horizontal expansion and thus, it is not free rising. When air rises in the chimney it also expands but only into upper direction. It compresses the layer of air above it, heats it up and loses its own heat. At the same time air below does the same thing. And thats how it goes all the way until the chimney exit: layers of air are being pushed and push themselves. That results in maintaining the same amount of heat in every layer of air, and that is how the chimney works.

This explanation ignores gravity. Air above you exerts more pressure on you than air below you, albeit by a tiny amount. But when the only thing moving is air in a 5-kilometer chimney, you can't get something for nothing. For intuition, just imagine the chimney is full of water. The water at the bottom is obviously under more pressure than the water at the top. The chimney faces the same consideration, but the ideal gas law applies.

Furthermore, the equation used in the "Calculations" section:

>q = dh2 /4 [ (2 g (po - pr) h ) / ( (l pr / dh) + pr ) ]

is sourced from this website:


which rather obviously works from the assumption that the chimney is placed inside of a heated house.

This all seems to be a sort of Sokal effect in climate science, I'm afraid. The paper 'SubiculumCode cited does not really analyze the thermodynamics used for the chimney and points more to the unrealistic dimensions (1 kilometer diameter and 10 kilometers high).

But the basic concept appears to be the same. Quite a few of them are from many years ago. So it would seem the idea works to some extent, and perhaps the the idea of a much taller, and flexible variant is the crucial difference that will make a big difference.

I have trouble understanding this mindset. It's like, if you were walking away from your car in a parking lot, and someone said "Hey! You've left your car unlocked!", and you yelled at them angrily "Stop looking at my car!!!". It makes no sense at all, and yet it's practically the universal response from people who don't know what they're doing.

People occasionally suggest that software engineers should be professionally licensed. I have a different proposal: I think that people who want to manage a business involving software development should have to get trained and licensed.

ETA: while my proposal is somewhat facetious when considered about all software development, perhaps it's not completely inconceivable that we could require businesses collecting any personal information from users to be licensed and audited. We already have PCI-DSS compliance rules for businesses using credit cards; this would be analogous, though it would have to be enforced by the government, as credit cards wouldn't necessarily be involved.

I wound up fixing it for them on the way out (after weeks of telling me it wasn't a concern). A simple command line script would have deleted the entire database leaving the university with no budget for the upcoming year. Another place I worked kept production passwords in the code repository; when I complained they told me they passed their audits every year so it didn't matter. HIPAA company in the US no less.

I was involved with one of the bigger ICO right at the beginning of the ICO craze. I had pretty regular conversations with the project founder and was in talks to become the dev evangelist. The project had raised ~$5 million in ETH (this is when ETH was trading around $80). Despite the fact that this project had raised a crazy amount of money the whole project was being conceptualized and coded by a single 23 old guy who was promising features that much larger projects with teams of the best people in the field were yet to solve. Not to mention the project was blatantly lying about it's PoW algorithm.

When I tried to point out that the project should use some of that money to organize the software engineering aspect the founder got pissed off with me accusing me of trying to run the project. They had a second round and raised even more money (in addition to the insane capgains on their first round).

I check the github from time to time and it appears they've got at least 2 other devs involved and may actually bring a blockchain to market but this doesn't hide that fact that the project needed nowhere near the amount of money they raised. Hell they could've used a couple hundred grand from the first round and literally just paid a team of people to build the blockchain for them. did I get off of a gravy train? Yes. But there are more things to life than money.

There is very little skepticism or research with these icos . Most of the commenters are trying to help the project and receive tokens in return, do tasks to qualify for free tokens ( bounties ) , or promote the ico so their token value increases

The SEC guidance galvanized us on not offering tokens. Instead, we are going to offer shares directly in the company, even if they are mostly issued via an ERC20 contract. If we are going to get heat from the SEC, might as well go all out and issue proper shares.

Plus tokens don't even make sense most of the time. You can't buy a Tesla car with TSLA and you do not get dividends/trading with a car. And no one outside kids at Chuck E Cheese want to use venue-specific currency.

Even the SEC realizes that not all token sales are securities. Some people in the industry simply aren't getting it, they are creating a straw man which the agency isn't even arguing for.

So there are all these people on the periphery just HOPING for their prophecy of a heavy handed government breaking the cryptocurrency rush.

They read the headlines.

They create the headlines.

They purposefully don't read the SEC report or consider any information to the contrary of what they are expecting.

Despite S.E.C. WARNING? This is an article about everyone getting smarter and restructuring their offering where necessary, and continuing to move forward.

Even the WARNING in the SEC's DAO report two weeks ago acknowledged that not all token offerings were securities. But detractors and regulated entities with a legitimate reason to be skittish, used it as the WELP SHOW'S OVER GUYS argument which is completely unfounded.

> Nick Morgan, formerly a lawyer in the S.E.C.s enforcement division, said that the security label was likely to apply to any coin that an investor buys with the expectation that it will increase in value as a result of the efforts of the entrepreneurs who created it.

The SEC still answers to the courts, and this consolidation of capital will allow these new organizations to take it to the courts efficiently. The Howey test from the 1940s did not consider this kind of asset to ever exist. It isn't an end all be all, it is a test.

The SEC is not mandated by Congress to undermine interstate commerce, it is created to provide confidence. So far, they've been playing it smart.
