"Breaking news! Corruption and totalitarianism of the Russian government, KGB and orthodox church exposed by the unimaginable injustice dealt to the members of the Pussy Riot and undisputed chess champion Gary Kasparov"

Anyways, here's what I was motivated to write in an earlier post on this topic:

Why isn't Madonna or these other outraged people protesting over the 32 miners killed in South Africa?
I understand 3 years (or is it 2?) is a tough punishment for what is basically vandalism by western standards (although I'm sure we can find examples or worse injustices in any of the western judicial systems). The organized and overblown reaction to all of this is much more about ruining Russia's reputation as a democratic nation than anything else. I've actually heard the nightly news-anchor here in Canada report on "International condemnation" of the sentencing. Are you fucking kidding me? Miners being gunned down for protesting in South Africa, Omahr Khadr still sitting in Guantanamo for something he might've been involved when he was 16, all the Wikileaks shit from Iraq Afghanistan... and the Pussy Riot going for a 2 year stint for vandalism is causing "international condemnation"?! If anything's made me aware of how alive the cold war is, this is it.

Also this:
I don't want to be misunderstood.. I'm in favour of Kasparov and the Pussy Riot doing what they're doing and fighting for a better government in Russia... as anyone should be doing for their country! But I am just irritated by the "better than thou" indignations echoed in media channels of the equally unjust western world that tends to ignore massive wrongdoings that are too inconvenient to the larger narrative.

One fragment from a BBC documentary by Adam Curtis explains rather well the mechanics of current Russian pro-democracy campaign in the Western media. http://www.youtube.com/watch?feature=player_detailpage&v...

The video deals with PR guru Edward Bernays work for his client, a United Fruit Company (UFCO). When a newly elected Guatemala president Jacobo Árbenz threatened to nationalize UFCO's plantations, Bernays engineered a campaign to turn the popularly elected president doing hugely popular things for his people, into a threat to democratic values and a communist with links to Moscow.

In reality, Arbenz was no communist and no dictator, as the documentary points out. But Bernays has set up a shell American press agency which bombarded US media with reports about alleged freedom violations in Guatemala. Bernays has also apparently organised a few violent anti-US actions in Guatemala to support his thesis.

As a result, president Arbenz was ousted in a coup and replaced with a proper dictator, which was generally viewed as a good thing by the freedom-loving public in the US. Interestingly, the whole time the United Fruit Company has been kept out of the picture, even through it was paying for the campaign.

The whole BBC documentary http://centuryself.blogspot.com/ is quite interesting.

Kasparov is a totally manufactured 'Russian opposition' figure.

As late as 2004 he was a member of a US "Security Advisory Council" (NSAC). It was funny to see Kasparov's name on the website under the slogan: "Advisory Council members have dedicated their careers to American security", right next to assistant Secretary of Defence
http://img717.imageshack.us.nyud.net/img717/1337/kasparov.jp...

I respect his anti-Putin views, and his chess achievements, but how exactly can he make a political career in Russia with such a background?

His current role is to get beaten occasionally by the police and to remind Western audience that Russian president is evil.

The most intriguing part of this affair to me has been the revelations of the patriarchy as basically tools of the KGB and now Putin. The airbrushed out $30K watch that bloggers found the reflection of. Wild stuff.

Kasparov's political role is interesting. He's been a thorn in the regime's side for some years now, but has only been moderately harassed. Not entirely sure why; perhaps the cost/benefit analysis of how much they fear him (probably not greatly) versus how much negative PR they get from going after him.

I know a lot of people believe Putin saved Russia, but I gotta say, having the same people in power for too long is never a good thing: they get comfortable, they lose their focus, things get stagnant and everything goes downhill from there.

There's a reason why the US does not allow the same person to be president more than twice in their life (although that doesn't stop them from putting someone they trust in power).

Karsparov has a history of staging or attending protests and getting arrested. After his chess career ended he has been trying to reinvent himself as a "people's champion" and "pro-democracy" leader. So far this has mostly amounted to him getting marginalized and beaten up by police.

As far as I can see, this is too bad for consumers AND start-ups.

Consumers lose - For example, I lost a very important feature on my phone due to a ridiculous patent threat by Apple (Universal Search).

Start-ups lose - I know atleast a couple of friends who were working on an innovative Adreno-Android based project that they left off only because of the fear of being sued (also,they were bootstrapping and they didn't have the money to afford a counter-suit, in case of a legal threat).

Now this is exactly the kind of behavior these patent wars are driving us to. Everyone is to blame here, but I personally have a heavy bias against Steve Jobs because he was a man who invented nothing useful except these patent wars. And boy, people keep praising him instead for his innovation...Seriously, we need more articles on how much innovation this man has ruined more he has contributed ever.

There are a lot of 'Apple deserves this' type of comments in this thread that I'd like to address.

The patent system is probably flawed (IANAL), but companies do need to have a way to defend their innovations. Apple did re-invent the smart phone in 07, and has been the design leader since then.

Android has followed in their footsteps - witness the design shift from their pre-iphone roadmap which consisted of blackberry-look-alike designs.

Further, there have been no bold re-imaginings of the smartphone in Android-land (sorry, a better notification system doesn't really qualify). They are taking Apple's innovations and applying a different business model to achieve success.

Google and Apple are both amazing companies, but I have a hard time finding fault with Apple's decision to sue Google's partners. If the tables were turned, and Google came out with an Android phone first, I would support Google suing Apple for the same reasons.

This article gives a good overview of how to use the build system in Sublime, though I always feel slightly pea-brained when articles like this pop up because they omit the very simple cases and that seems to be all I use.

If you use Sublime Text and just want a build system to save and start HTML pages when writing HTML and JavaScript, you can simply do:

Tools -> Build System -> New build system, write:

    {
// or add the chrome path to the environment
"cmd": ["C:/Users/ThyUsername/AppData/Local/Google/Chrome/Application/chrome.exe", "$file"],
"selector": "html"
}

and save. CTRL+B then saves your html file and opens it in Chrome. I think on a Mac you'd do:

    {
"cmd": ["open", "-a", "Safari", "$file"],
"selector": "html"
}

Initially, I used the sublime build system for doing grunt builds as well. However, I've migrated towards using 'grunt watch' instead. Running your build on every file modification is pretty great. Combined with the SublimeLinter package, it's about as painless as I've experienced in web dev.

How We Nearly Lost the Discovery Shuttle waynehale.wordpress.com

Every Shuttle in the fleet has had one or several extremely close scrapes with death. To look at the Shuttle record and see the history of calamity it's easy to think that we just had bad luck, but quite the opposite was the case. We were enormously lucky with the Shuttle, in a fairer world we would have lost more of them, and sooner. The Shuttle was plagued by many fundamental design flaws which combined to make it an inherently unsafe system. Within the last years of the program that knowledge finally started to sink in, which is why the Shuttle was essentially restricted to missions to the ISS.

Some of the achievements of the Shuttle program have been inspiring, and the vehicle itself is pretty to look at, but we should have canned that program long, long ago.

"We informed the foam technicians at our plant in Michoud Louisiana that they were the cause of the loss of Columbia..."

That to me is pretty disgusting. In an incident like the loss of Columbia, there is no one, true "root cause". To assign blame to those foam technicians was disingenuous and just another instance of "passing the buck" that seems to happen so often in the post-mortem of NASA failures. NASA knew of earlier foam strikes (STS-112) yet chose to continue flying without diagnosing the problem. Even during the tragic STS-107 flight, engineers knew of foam strikes and their concerns were ignored. Even though they would have been almost completely powerless to remedy the situation on STS-107, the higher-ups decided to continue on with the mission instead of addressing the concerns with the heat shields. The article author states later in the article that he apologized to the foam technicians. Commendable, but I am still bothered by the fact that NASA was initially so eager to place the blame on a single contractor instead of owning up to their own culpability. Leadership and responsibility needs to come from the top, especially in such a prestigious organization!

A great post, especially since it seeks to get at the truth of something that has implications for future missions, at the risk of the OP's reputation.

This part is one of the more disturbing parts though, and a good reminder of why technical persons of all fields, whether rocket scientists or programmers, should not adopt a "Well, we worked hard and we're smart so I'm sure everything's fixed"

> What you probably don't know is that a side note in a final briefing before Discovery's flight pointed out that the large chunk of foam that brought down Columbia could not have been liberated from an internal installation defect. Hmm. After 26 months of work, nobody knew how to address that little statement. Of course we had fixed everything. What else could there be? What else could we do? We were exhausted with study, test, redesign. We decided to fly.

How is it that this mentality exists at NASA? Isn't it a matter of logic that if the foam was shown not to have been an installation defect, that the engineers have to keep looking for the actual cause? The OP just brushes over this but surely there was some kind of debate, like: "Well, the particular test claiming that the foam was NOT an installation defect was poorly conducted, and all our other measurements say that the installation is the likely cause, so moving on..."

I really hope there isn't some kind of "Oh fuck it, just ship it" mentality at NASA.

The lesson I take from this is that the Shuttle should have been killed on the drawing board, never flown. It's a hideously complex design with no real advantages over expendable or re-usable rockets. It might have made sense as part of a tens of trillions of dollar integrated infrastructure plan (as originally proposed in the 1970s), but once those elements were killed, zombie/frankenstein shuttle wasn't the right answer.

NASA could have focused more on great science programs (like the Mars rovers, unmanned deep space probes, planetary science -- think of what they could accomplish with even 50% of the current overall NASA budget), military and government launch could have continued with ICBM-derived rockets, and private space could have gotten an earlier start.

This reminded me of the problem of unit testing vs integration testing. Sometimes, no matter how much code coverage you have, the unit tests don't find that critical bug that takes everything down.

Yes, I know I shouldn't say it out loud, but here I am saying it (take me, Police) - out of curiosity, I went to Hard Candy section of The Hidden Wiki. (Yes, it is exactly what you would think it is.)

GOD.

There are seriously forums full of pedofiles sharing pictures and - maybe worse? - their stories and wisdoms. Maybe out of utter fascination, I spend about few hours on there and I felt like I want to murder all humanity. On one of these forums, there was this alleged "doctor", who adviced people, from what age you can have sex with your children without their doctor to notice. Tips how to kidnap young children. The worst thing was that I just knew that - if they don't do something stupid - they are basically untracable and uncatchable, while I would simply want to catch them all and kill them one by one. (I am sorry for being so expressive.)

There were also some picture forums but really I couldn't stand that, I just wanted to vomit while I was shaking.

I... am not sure why I am writing this. I am all for Tor. But we have to admit - when everything is allowed and anonymous, EVERYTHING is allowed and anonymous. And the dark parts of humanity flow on top. Drug markets, weapon markets, assasin markets (altough I don't know how sersiously to take those), terrorist websites, child porn websites.

But - as hard it is for me to say it - to see that the seriously f...d up child molesters are freely allowed to say really anything there and noone has a chance to catch them just shows that Tor is really anonymous and safe.

edit:
I do not know if The Hidden Wiki is still operating, if the dark places I visited are still operating, it is about one year and I did not feel any urge to revisit it again.

Ooh, the Tor darknet. I went there recently out of curiosity. You can get used to doing everything over Tor quite quickly, if you use it for everything you don't really notice the latency.

Yes, Tor has CP, but I didn't look for it so I didn't find it. Same with all manner of other illegal content, pretty sure it's there.

I2P and Freenet are more interesting than Tor, though, because they are truly P2P. Freenet is basically a distributed hash table (DHT) for HTML, CSS, image, and other files. It filters scripts and cross-origin requests out of HTML before serving them. I2P is like Tor, but everyone's a relay node (truly P2P, no central origin), and it's faster, but I haven't tried I2P. I have been on Freenet... it's slower than Tor!

A word of advice for those living under truly oppressive governments - do not connect to Tor directly (nor to a Tor bridge, to be on the safe side). Get a cheap VPS/EC2 abroad and use SSH tunnel to connect to that and from then onwards - to a Tor bridge. The reason is that, if connecting to Tor directly, security services will be able to figure out you are using Tor (although not what you are using it for) and may take an interest.

I wish there were a simple way to communicate how large and widespread CP is, and how much law enforcement could use your smarts to go after these guys.

There are more households sharing CP in your community than there are bus stops. (We can roughly map IPs of known CP files advertised over torrent networks.)

There are too few innovators in this space because specifics on CP networks are privy to law enforcement, and investigators are often patrol cops who get promoted into a child crimes unit.

It's fine (and true) to say these technologies are used for many more things than CP, but that's not an excuse to turn a blind eye to it, anymore than Craigslist does to child exploitation.

Tor is also the solution to your Twitter API woes. Like it or not. I'm sure many SEO people use it to get around Google's restrictions. These are not necessarily uses that infringe anyone's IP. Twitter is UGC. And Google caches the entire web, indiscriminantly.

Tor, like the 'net itself, is controversial. It can be used for bad things. It can also be used for good things. It could be used to break criminal laws, or to enable copyright infringment. It could be used to violate TOS that may or may not be enforceable in civil court. Or it could be used just to evade idiosyncratic censorship by some webmaster that has no legal basis whatsoever. (This comment itself is being posted through Tor.) It is, however, any way you look at it, useful.

There may be an "intended purpose" for Tor. But as with almost all software, that means little. Users decide how they will use it. And that is unpredictable.

Did the folks at MIT, when they developed Tor, say to themselves, "You know, this will be used to commit crime"? Probably. But they also probably envisioned some other uses that were of undisputed benefit to society.

As someone else said, MIT is still behind Tor. Grep the source for the Tor client for IP numbers. You will find that some belong to MIT. My understanding is that Tor is controlled by a small group (maybe only one person) because like anything else that uses a network, there has to be a bootstrap, a "root" that hands out the initial addresses. And anyone that uses the Tor trusts that root. Somewhere there is/are a few people with a great responsibility on their hands: they make Tor possible, for better, or worse.

More people need to use Tor for non-criminal purposes. Using Tor as a workaround for censorship, whether it is on HN, or in some oppressed country is to be expected. If you are the censor, and you don't like it, ban Tor. It is not difficult.
HN does not ban Tor.

One of the great myths on the 'net is that an IP address equates to a machine or a customer account. False. It represents an interface, which is itself an ephemeral concept. Interfaces can be created, cloned or destroyed at the blink of an eye.

This may all be frightening or it may be exciting, it all depends on how you look at it. It shouldn't matter whether you are a good samaritan or a criminal. It is just technology. Abstract tools. A hammer can be used to build something or it can be used to destroy something. It has no moral sensibility on its own.

That's up to you, the user.

As a Tor user (I can't post to HN without it), it bothers me that others are using it for criminal purposes. But when I look at hammer, I see a tool for creation, not destruction. I think like a carpenter. What can we build?

The hammer has no consciousness of its own, any more than Tor does.

Harvard cracks DNA storage, crams 700 terabytes of data into a single gram extremetech.com

I really liked their paper. Its a bit less over the top than the extremetech guys but hey, that is the difference between pop journalism and science.

Clearly with some form of fountain code or LDPC codes you will be able to get the data back, but what struck me is that I always thought of DNA as relatively unstable, in the sense that cells decay/die etc, but the fact that just sitting there, DNA which isn't expressing various proteins under the influence of other cellular mechanisms, well it just sits there. That was new for me.

When I showed it to my wife she pointed out that the sourdough starter she has been using since we were married was from her grandmother, I joked that the next megaupload type raid would have to sequence all the DNA the found in a place to figure out if Shrek3 was encoded in it somewhere. That would be painfully funny I think.

If you store data onto 50 DNA strands, can you always read back all the data from all 50 strands, or does one need to store multiple copies of each in case the sequencer can't "find" a particular strand?

If one does need multiple copies, it would seem that this method suffers from the coupon collector's problem [1] (i.e. to collect all 50 strands requires collecting 225 random strands on average), and that the retrieval rate could be improved by using a fountain code [2], which allows each strand to simultaneously encode data at multiple addresses, which would decrease the number of strands required to be sampled to only slightly more than the number of strands worth of data requested.

This article is incredibly misleading. First of all there is an inconsistency. The headline says they stored 700 terrabytes (4.4 petabytes). It then later says that they actually stored 700 kilobytes (Their book) and that they did made 70 billion copies (44 petabytes?). The main thing is that storing 700 kilobytes and then making 700 billion copies is considerably less useful than storing 70 billion terabytes outright. Aside from that though, this is awesome, and a huge step forward into promising and uncharted territory.

I notice that the article fails to mention how long it would take to extract all 700 terabytes of data...

Assuming 5.5 petabits stored with 1 base pair representing 1 bit, we can extrapolate the time required to extract the data based off the time taken to sequence the human genome (3 billion base pairs).

5.5 petabits / 3 billion bits ~= 2 million, so theoretically it should take 2 million times longer to sequence the original.

3 years ago, there was an Ars Technica article about how it now only takes 1 month to sequence a human genome[1]; the article now claims that microfluidic chips can perform the same task in hours.

Assuming 2 hours (low end) to sequence the human genome:

2 hours * 2 million = 4 million hours = 456 years, give or take a few years.

So, maybe not so great for storing enormous amounts of data. But if you want to store 1 GB, it would only take ~6 hours. Not too bad.

This result doesn't seem all that impressive. In the end it's just an example of the advantage of being able to pre-commit to a strategy. The linear algebra parts are entirely unnecessary.

For example, suppose we're playing the iterated prisoner's dilemma. I pre-commit to a strategy: if you've defected in the last 5 games I will always defect, otherwise I will defect unless I haven't cooperated in the last 4 games. In this situation your optimal strategy is to always cooperate, even though I'm taking advantage of you. Punishing me won't change my strategy, I've pre-committed to it. The rational strategy, and the one evolution would eventually settle on, is to always cooperate with me.

Commenters seem to be missing the point of this. Go visit the signup page, and right at the bottom you'll see this tagline:

If you can spare $50 for a social network I'm guessing you can spare $50 to help put an end to slavery. Yeah, it's 2012 and it's still a pretty big problem. That shit is unacceptable. Really. </whiteguilt>

Personally, I'm not the fan of the "don't spend money on anything until the world's problems have been cured" style of thinking, but it's certainly a novel idea.

Now all they have to do is fix the title of the signup page. Right now it says Signup For App.net.

EDIT: Interestingly, the domain name of freetheslaves.net belongs to "Superhuman Ventures, LLC." I don't know enough about how people taking donations work, but I find it pretty strange that Free The Slaves have a long list of directors and staff (https://www.freetheslaves.net/SSLPage.aspx?pid=285) but no mention of what their corporate structure is. Is this unusual? Should they explicitly be a charitable organisation?

Yeah, sounds stupid to spell it out like this. Not everyone knows what app.net is, nor what its backstory is (I still don't). Ergo the spoof garners a well-deserved WTF.

This is for a Charity? Well they botched that then IMO.

After clicking the top "alpha.ihave50dollars.com" link (and others) you end up at heello.com. So I then understandably thought the site was a "snark-attack" by the Heello/Twitpic guys.

After all, Heello was started by Twitpic when Twitter was just starting to clamp down on their API usage and was about to start their own photo service -- so Heello was started pretty much in the same spirit as App.net was -- at least in the sense of "Hey! I'm pissed at Twitter, so now I'm gonna make a competitor clone".

So I wonder, why doesn't anyone mention this Heello? Does the App.net guy have more Hacker Mojo than the Twitpic guy? Is this Heello guy pissed that App.net got paid $700k+ for doing what they wanted to do 1-2 years ago?

Hmmmm...

Where Dalton is going I don't know (and I feel he's generally a pompous ass when he speaks/writes) but... I think app.net is a matter of OWNERSHIP. Ownership of your data and ownership of the company.

Companies are beholden to those who pay. If it's the users who pay, the power is with them. I like that idea. If it's the advertisers, they don't need to care as much about the user, see FB and Twitter.

Stuff DOESN'T have to be free. I pay for many things, and in general the things I pay for are better than things which are free.

This is quite funny, it made me chuckle.

Now, putting the joke aside, let's be real. Whilst the majority of you aren't willing to spend $50 (Including myself), the fact is, some people already have and they have managed to raise a lot of money.

I suppose it doesn't matter what product you have as long as you know how to market it and most importantly, solve a problem.

Whilst App.net may be ideal for developers because it considers their requirements, I highly doubt whether main stream users care the problems that App.net is trying to solve. None of my friends would pay for a social network, and neither would I. Why? Because I can use my phone and there's plenty of other free alternatives.

Either way, I wish App.net all the best but I rather keep my $50.

tomku 17 hours ago 1 reply      
Thanks, downloaded and read through it and I picked up a couple new tricks, even as a pretty experienced Vim user.

Some comments:

1) The order feels a little artificial. I like that inserting text isn't mentioned until a couple chapters in, but I think that the focus on saving/writing files at the start is misplaced. If I'm a newbie and I don't know how to change or insert text, I don't have the ability to meaningfully practice saving as I read.

2) There are some weird inconsistencies, like teaching :next (:n) for next file, but Ctrl+^ for previous file. :Next (:N) is easier to remember, works in vi and is shorter to type than the less-compatible :prev that I would otherwise suggest. :! is mentioned several times in different contexts, without a hint that it's the same command in each but with a different prefix or argument.

3) There's a focus on memorization of compound commands rather than understanding how motions and operators work. If you know how the cursor works and that "y" means "yank from cursor", you don't have to remember that "yl" means "yank a single character" because you can compose it from "yank from cursor" and "one character to the right". This composition of movement and operators is one of vi's greatest strengths, and I think that exposing new vi users to it as early as practically possible is a great way to get them to appreciate what they're learning.

All in all, it's a worthy read for someone who doesn't know any vi and needs a quick lesson in the basics, somewhat like the foreign language learning products that focus on teaching you enough conversational vocabulary for a vacation or business trip. If you want to immigrate to vi-land permanently, I'd suggest supplementing this with something like Drew Neil's "Practical Vim"[1] to learn the "bigger picture" stuff as well.

Once every six months something inspires me to put a book on the Kindle that I received as a Christmas present two years ago. Then the frustrations begin. In this case, after finding the table of contents I try to use the up-down-joystick-button to navigate the TOC. It's just painfully slow and it's displaying definitions for every word I happen to be on (it starts off showing me the definition for "Table" in Table of Contents). The lag between pressing the button and the cursor actually moving is too frustrating for me to even use the damn device.

Perhaps the "two years old" is my problem and I just need a newer device but, boy, I just can't get myself to use this thing with any consistency.

On a related note, is there an easy way to find other free or dirt-cheap (US $0.99) E-books on Amazon?

The Amazon site likes to group things into "As low as <price>" sections, which means there's a least one item at that price, with most things costing more.

OnLive assets acquired by newly formed company techcrunch.com

hncommenter13 8 hours ago 1 reply      
There appears to be quite a bit of confusion as to what happened here. The TechCrunch article doesn't really provide enough detail, saying only that the staff was fired in order to "reduce the company's liability" which doesn't really make sense.

I am not a lawyer, but as an investor I have seen this happen before. My guess (no connection to the company, wasn't aware of them prior to today) is that in lieu of filing for bankruptcy, they did an Assignment for the Benefit of Creditors.

But what may have happened is:
1. OnLive recognizes that they're essentially bankrupt. Directors and managers now have a fiduciary duty to maximize the recovery for creditors, not for shareholders.

2. Instead of going through a formal bankruptcy process, the company does an Assignment for the Benefit of Creditors (see a good explanation here [1]). Any price paid for the assets by a buyer above what is owed to the creditors goes to satisfy the liquidation preferences, though it's unlikely there will be much if any recovery of value above the debts owed to the creditors. The value of the common equity is totally wiped out (both common stock and employee options) as the total value of the assets is well below the amount due creditors + the liquidation preferences.

3. A buyer for the assets (the source of money with which to pay off the creditors who now own the assets of the defunct company) forms a new company, call it OnLive Asset Acquisition Corp.

4. OnLive Asset Acquisition Corp purchases the assets (not the stock) of the defunct corporation now owned by creditors. The new acquirer buys the assets so as to avoid any existing/potential liabilities of the defunct corporation from whom it purchases the assets. Imagine there's a company whose only asset is a rack of servers that you wish to purchase. To gain ownership of the servers, you could buy all the shares of the company or you could just buy the servers as an asset with no encumbrances. You would likely do the latter, as buying the stock comes with potential liabilities for past/future money owed or lawsuits. That's likely what happened here, but for IP, etc.

5. The original employer OnLive is no longer operating. The employees are all terminated, as their employer is gone and its operating assets are owned by a new company. The new company may or may not seek to hire some or all of the employees of the defunct company.

6. Even if employees had been able to exercise their options, they were virtually certain to be worthless. There is no way the price paid by the new owner for the assets of the dead company would exceed the debts + liquidation preferences (otherwise the directors wouldn't have liquidated it). Had the employees exercised their options, any cash they paid to do so would have gone to the creditors to satisfy the company's debts and they would have received zero in proceeds.

It's a sad story for the employees, but there are rarely any happy outcomes for a company in bankruptcy.

Again, I'm purely speculating on what happened. But based on the facts disclosed so far, it's not clear that one can conclude that the employees received a specific and unusual screwing by management vs. a typical screwing associated with the liquidation of a bankrupt employer.

This article is bullshit. The CEO of a company cannot "take back" or "wipe out" your right to purchase stock, aka stock options.

More likely what happened is that the company sold for equal or less than the outstanding preferred stock overhang. Another way of saying this: OnLive's investors got all the money (they raised $56MM) and the founders and employees got ZERO for their common stock.

A stock option is a binding CONTRACT to purchase stock (typically common stock when you're dealing w/ employee stock options) at a set price. If a company is acquired and the price of common stock is below the "strike price" of the employee stock options then the employee has a valueless option to buy stock for more than it's worth.

Oftentimes in an "exit" that's just shy of bankruptcy, common stock holders will get nothing and investors will get all the proceeds, often at pennies or nickels on the dollar.

So... Did OnLive screw its employees? Highly unlikely.

Luckily this sort of thing rarely happens. The reason is that you need great engineers to trust you if you want to succeed. By founding a startup you are taking great personal risk, but your employees are also taking some of that risk with you. Most startups pay (very very) below market salaries, and bring employees up to parity with a much less terrible place to work (very few very bright people would prefer to work in at a big company), and by giving out options.

I suspect that the CEO and other high level managers at this company will have serious trouble recruiting the next time they want to start something new, because they now have nothing to offer. Nobody is going to trust their promises, stock options they issue will be seen as basically worthless (since everyone will think they are likely to be screwed out of them), so they will have to pay market rates (which is probably 2x-6x what startups generally pay in total compensation).

If I were a founder of a company, and I were faced with this choice, I would probably rather let the company fold than cash out (or in this case probably just not go under) while leaving employees behind. Failure is rarely punished in the valley, but nowhere is dishonesty or double dealing more likely to be recognized and rejected.

I'll accept that there's a lot to be learned from stool, but I don't think this explanation has much to do with it:

“Have you ever figured how information-rich your stool is?,” Larry asks me with a wide smile, his gray-green eyes intent behind rimless glasses. “There are about 100 billion bacteria per gram. Each bacterium has DNA whose length is typically one to 10 megabases"call it 1 million bytes of information. This means human stool has a data capacity of 100,000 terabytes of information stored per gram. That's many orders of magnitude more information density than, say, in a chip in your smartphone or your personal computer. So your stool is far more interesting than a computer.”

Small, implanted labs-on-a-chip will eventually solve the data gathering problem. Software and lots of data (both your own and others suitably like you, where suitably is a thousands of times more specific than it is today) will identify the difference that are "normal" versus those that are "unhealthy".

This will upend the medical industry, which is one of the most inertial industries in existence. Worse, all the regulations that protect us will ultimately be used to protect it, in far worse ways than the whole RIAA/MPAA thing.

I hope technology can beat it.

So does this confirm that it was mostly done to get back potential equity? If so how many of the employees are likely to go back?

Or was this done because they ran out of money and it's the only thing to do so most probably will? Except why fire them and do all that song and dance?

Also I like how the staff is all fired and some rehired but the service remains operating....

SoftwareMaven 9 hours ago 0 replies      
If the company was sold for less than the investments (or not a lot more) and the employees really were fired, it likely represented no loss for the employees and perhaps a way to sweeten the deal for the acquirers. The employees don't see a loss, because their stock wouldn't pay out until after the investors got theirs (which may be at a minimum multiple). The acquirer has less risk because they can weed out anybody they don't want to bring along and the firing risk went to a defunct company.

Sad really. This reads like a legal maneuver to escape prior financial obligations. Fire everyone, sell the assets to a new company, have that company re-hire the staff (if they are stupid enough to work there) and then negotiate new contracts with various vendors until you are up and running. Meanwhile creditors, investors, and disgruntled employees are left to sue an empty husk of a corporation with no assets.

It will be interesting to see the ramifications on Perlman's career. In a valley that embraces shooting high and missing, this doesn't feel very 'gentlemanly' if you will.

I appreciate the distinction between arrays and pointers, but the article fails to mention a similar pitfall: A struct is the sizeof its members., which isn't necessarily true.

It's like how everyone learns that (INT_MAX + 1) == INT_MIN (even non-developers seems to know this) yet that it actually is undefined (in C/C++), I feel that just noting that it isn't the whole truth (such as noting that the OS handles the memory behind your back) is quite valuable, even when learning the basics.

Otherwise you might end up feeling, as I do, that your foundation is shaky and built up on lies - not really knowing what "facts" you can trust.

"Arrays are not pointers". Right. And wrong, actually.

The article says that arrays are different from pointers, but it does not prove it. It is quite simple to prove, see the program below.

Also, it's not interesting to limit the definition of arrays to just the locally and statically declared ones. If you do that then something like 90% of C programs (if not more, I think I never wrote such a C program except for exercises in class) don't use arrays at all. In all the other case (arrays passed as argument to a function, dynamically allocated arrays…), the are the same as pointers. Again, see the program below.

In reality, it is a bit pedantic to insist on this distinction, except for the rare case where it is a performance issue (the arrays of the article require one less memory access, the one to get the address of the memory at which the array starts).

    #include <stdio.h>
#include <stdlib.h>

void
f (char a[], char *b, char *c)
{
printf("Once passed to a function as arguments:\n\n");

printf("What the article limits the definition of array to:\n");
printf("&a = %p\n", &a);
printf("a = %p\n", a);
printf("&(a[0]) = %p\n", &(a[0]));
printf("a + 1 = %p\n", a + 1);
printf("&(a[1]) = %p\n", &(a[1]));
printf("\n");

printf("Pointer to an array:\n");
printf("&b = %p\n", &b);
printf("b = %p\n", b);
printf("&(b[0]) = %p\n", &(b[0]));
printf("b + 1 = %p\n", b + 1);
printf("&(b[1]) = %p\n", &(b[1]));
printf("\n");

printf("Pointer to dynamically allocated memory:\n");
printf("&c = %p\n", &c);
printf("c = %p\n", c);
printf("&(c[0]) = %p\n", &(c[0]));
printf("c + 1 = %p\n", c + 1);
printf("&(c[1]) = %p\n", &(c[1]));
printf("\n");
}

int
main (int argc, char *argv[])
{
char a[4];
char *b = a;
char *c = malloc(sizeof(*c) * 4);

printf("What the article limits the definition of array to:\n");
printf("&a = %p\n", &a); /* behavior differs only here, this is the
difference with pointers */
printf("a = %p\n", a);
printf("&(a[0]) = %p\n", &(a[0]));
printf("a + 1 = %p\n", a + 1);
printf("&(a[1]) = %p\n", &(a[1]));
printf("\n");

printf("Pointer to an array:\n");
printf("&b = %p\n", &b);
printf("b = %p\n", b);
printf("&(b[0]) = %p\n", &(b[0]));
printf("b + 1 = %p\n", b + 1);
printf("&(b[1]) = %p\n", &(b[1]));
printf("\n");

printf("Pointer to dynamically allocated memory:\n");
printf("&c = %p\n", &c);
printf("c = %p\n", c);
printf("&(c[0]) = %p\n", &(c[0]));
printf("c + 1 = %p\n", c + 1);
printf("&(c[1]) = %p\n", &(c[1]));
printf("\n");

f(a, b, c);

return 0;
}

Here is a possible output of this program:

    What the article limits the definition of array to:
&a = 0x7fff5590ff00
a = 0x7fff5590ff00
&(a[0]) = 0x7fff5590ff00
a + 1 = 0x7fff5590ff01
&(a[1]) = 0x7fff5590ff01

Pointer to an array:
&b = 0x7fff5590fef8
b = 0x7fff5590ff00
&(b[0]) = 0x7fff5590ff00
b + 1 = 0x7fff5590ff01
&(b[1]) = 0x7fff5590ff01

Pointer to dynamically allocated memory:
&c = 0x7fff5590fef0
c = 0x202f010
&(c[0]) = 0x202f010
c + 1 = 0x202f011
&(c[1]) = 0x202f011

Once passed to a function as arguments:

What the article limits the definition of array to:
&a = 0x7fff5590fec8
a = 0x7fff5590ff00
&(a[0]) = 0x7fff5590ff00
a + 1 = 0x7fff5590ff01
&(a[1]) = 0x7fff5590ff01

Pointer to an array:
&b = 0x7fff5590fec0
b = 0x7fff5590ff00
&(b[0]) = 0x7fff5590ff00
b + 1 = 0x7fff5590ff01
&(b[1]) = 0x7fff5590ff01

Pointer to dynamically allocated memory:
&c = 0x7fff5590feb8
c = 0x202f010
&(c[0]) = 0x202f010
c + 1 = 0x202f011
&(c[1]) = 0x202f011

As we can see, for their practical use arrays and pointers can really be seen as the same thing. So again, except if you are optimizing a program where you can statically declare your arrays and access them a lot (i.e., you are doing matrix multiplication), the difference between arrays and pointers does not really matter.

One thing to note:

Maybe you should explain the first element of an array having the same memory address as the actual array a little bit more, and relate it to why array indexing is 0-based too - the index is that many offsets from the beginning from the array.

Nice introduction. I think it is worth pointing out that much of what you discuss is implementation dependent, the c standard doesn't require an implementation to lay out data in memory in any particular way. Instead it requires that access semantics behave in a particular way. These semantics, in turn, align with easy, low level implementations.

This doesn't surprise me at all. When you develop on someone else's platform, you have to walk a fine line between not being successful at all and being too successful such that the platform provider co-opts your business (maybe you get lucky and get bought out). This is nothing new. Such moves as this were (IMHO) inevitable. They'll slowly chip away at anything they see as taking revenue from them.

The part I disagree with is that this will doom Twitter. It will not. They've already achieved a certain level of success. Most people use and will continue to use the Website or the official client and be happy with that.

I do believe that Twitter is doomed to be acquired however. Apple seems the likely frontrunner for this but I think Twitter needs Apple more than Apple needs Twitter at this point.

Twitter is ultimately infrastructure and infrastructure seems doomed to commoditization. Twitter has eyeballs too but social platforms seem fickle at best. There is nothing preventing Twitter from becoming the next Myspace.

There are many reasons I'm glad about Facebook's floundering market debut. This is one of them: it's taking the wind out of the sails of the social hype (IMHO).

Of all the social media and web services that have cropped up in the last 5 years, Twitter was the one that really filled me with joy. It's so simple! It's just plain text in bite sized pieces at a time. And it's universal! It works just as well on state of the art hardware as it does on a crappy SMS dumbphone or green-screen serial terminal. And it's as compelling in Egypt or Pakistan as it is in New York or London.

Whenever I get fed up with the complextiy of Facebook or Google+ I'll load up Twitter on an old Apple II, via TTYtter and a serial connection; I'll watch the green text scroll along at 1200 baud and think about how this one simple, geeky text service, pure as a 1980s BBS, somehow made it, worldwide, in 2012.

And now they're hellbent on ruining all of that. Fuck Twitter.

Sometimes I tend to see the dark side of human in everything they do. Sorry, its just the way I am.

I say when twitter was still this little chick, their approach was "we love all users, we welcome engineers; build amazing tools and surprise us!". I think the reason for that was to speed up the process of spreading the word - a simple fact that geek working on twitter 3rd party is still a human with plenty of friends to spread the word about twitter - so he can be helpful: let him spend his time doing what he likes doing the best - programming and he will become our cheap (free) PR tube.

But now I bet most of a new age civilization knows or uses twitter. So it is time for a reality check: "fuck off of our platform; we don't need you anymore! You got all your friends to know twitter, some even addict to it; now stay away from trying to run your pathetic queries, using our own data stream".

Just my version/2c.

edit: my understanding is that Dorsey still has the most to say in the twitter world. With all its nastiness going on between twitter curtain, I say stay the hell far away from any startup he will do in the future. Sorry, but if he signs up half of the world on his square, what on Earth is stopping him from switching 2.5% to 10% fee?? nothing!! At least the past (present) shows he has the balls to execute moves that average tweeting Joe is not a fan of: shutting down 3rd parties, kicking out linkedin, shutting down instagram access, etc. Bottom line: stay away!

If Twitter's business is threatened by third-party apps, why not charge for an API license? I also can't quite understand why developers expect a free API from services like Twitter and then complain when something changes?

What is the business advantage of Twitter (or Facebook, or what-have-you) releasing a free, public API to anyone who asks, and how did they plan to monetize it when it got popular? You can't build your business model around "here, use my service for free" and not have a plan how to convert either the users of the 3rd party developers' software or the 3rd party developers themselves into paying customers (or monetize on that somehow, i.e. mining data, selling ads, etc). Maybe I'm just being naive -- I honestly don't have much experience dealing with these sorts of things, so I would love it if someone could break it down.

Unless platforms like Facbeook or Twitter make a significant amount of money from their devs, the way Microsoft or Apple does, telling their devs to go pound sand at some point is inevitable.

Twitter wants to give you access to the data. Their client is their main product. Thus, every 3rd party client is competing with their main product, that seems to be a fact.

Theres no way to stop you from building one anyway, twitter knows that. If you go against their rules, you're a revolutionary, and if you win that revolution, they'll have to deal with you.

You can't expect however, that the incumbent is going to go around encouraging revolutions against themselves.

The only alternative is to encourage everyone to make clients, at which point, they're just a big cloud xmpp server to the world.

From here, I think we should move to a distributed model, like email and xmpp.

It needs to be Open Source so anyone can run it and everyone owns their data.

It needs to be compatible with current Twitter apps so all it requires is setting the API root.

It needs to be distributed so anyone can follow anyone anywhere. There is no owner or root, there is no place to shut down.

Proof of concept: https://nstatus.herokuapp.com

Source: https://github.com/maxpow4h/nekomimi

I wrote about the requirements of it here: http://maxpow4h.com/blog/twitter/

edit: you can use any username with any password to sign in to nstatus. It then uses that password for your username. You can even do this from the official iOS Twitter app, just sign in.

Developers seem to flock to platforms like Apple, Facebook and Twitter based on the fact that they have a large and growing user base without giving thought to this issue of commoditization of complements and how the ultimately destroy the business or livelihood of these developers.

Most people building products or sharecropping on other people's platform never make meaningful income and yet those platform keep will prefer to announce large sums paid out to developers to encourage you to keep building complements. Apple will claim they paid out $5 billion but spread the numerous app developers it becomes peanut and not enough to pay their bills. They won't tell you that to pay out $5bn they made atleast $2billion based on their 30% cut.

They don't tell you that iOS app success is a "lottery": 60% (or more) of developers don't break even

can't say I blame them really. They have a product, they have the infrastructure to support it....why shouldn't they have right of first refusal on how to monetize the thing?

Seems to me that developers are getting all pissy because they can't have free reign to a platform that isn't even theirs. Perhaps, at the end of the day, Twitter doesn't care - they don't need the developers as early adopters anymore and it must be a fair old strain to keep the api infrastructure supporting them when the resources could be more profitably used building something else inside the company.

The only other reason I can fathom why they would doing this is they eventually intend to heavily push ads over their network, something that third party apps could interfere with.

I don't know if this is the worst thing that Twitter could have done, but it's probably fairly high up there. I wonder what people like Tapbot and thinking right now, they're grandfathered in for some very, very specific agreements but they know that one misstep and they'll end up out in the cold or paying a fortune.

But then what does that mean for a Tweetbot user like myself? Less incremental updates? One day the application breaks? Who knows, too early to tell.

I'm mostly surprised Twitter isn't just leveraging the fact they are pumping out that many requests and slipping ads or promoted tweets or promoted tweeters into the API stream and making cash off that. Seems like it'd make sense.

The large swath of discussion seems to be focusing on App Development, which is probably the hardest hit.

However, there's another area that has gotten me wondering, non-app, non-client based websites using the API, in reference to the Display Guidelines..er Rules.

This is the bit specifically.

"Users must have a consistent experience wherever they interact with Tweets, whether on Twitter.com, a mobile client, website, or in an application developed with the Twitter API"

So lets say that I go to GitHub and grab a little jQuery plugin to pull in my tweets on my personal portfolio. Does that also mean I have to make sure I include my own avatar, my username, Tweet actions, and twitter branding, among other things? What if those elements are unnecessary to the design or intention of what I'm doing on the site?

And then there's the fact that all of these jQuery plugins are going to have to start implementing authenticated access (if they weren't already, which many seem to not be.) I don't have access to data on the matter, but I would surmise that there's a significant number of personal and portfolio sites out there pulling in tweets that are either not authenticated, or are modifying the tweet display in some way. All the ones I've interacted with have settings for turning avatar display on or off, or unlinking hash tags or links, etc.

Thoughts?

Not bullshit, these are demonstrably useful products for people who want to utilize new traffic sources in the interest of making money or growing their business.

"But services like Storify and Favstar, which are actually useful and/or fun, those are no good."

ummm...ok? Utility is in the eye of the beholder...Twitter is a B2C product, so they're going to try and limit the number of competing services that are stealing B2C market share from them (why would you expect them to be ok with people using alternative Twitter apps instead of the official one?)

Now, Twitter is not a B2B company, so it makes sense that they would allow those types of services to continue. It's quite possible they're allowing B2B services that are utilizing the twitter platform to continue operating because they plan to acquire a few of them in the future to try and actually make a profit one day.

Since when did people consider unlimited access to Twitter's API an unalienable right? It is their platform, and their API. It's also completely free.

Twitter is absolutely free to limit usage of their own API however they wish. If it means they want to change the rate limiting on their servers, I see no problem with that.

The fundamental problem is that people like reading things that are written by people that have a slightly higher IQ than them (at least for people this side of 100).

The reason that this is a problem is that the average person has more friends closer to the median IQ than they do further away. So when people share new sites with one another they are generally sharing it more often with lower IQ people than they are with higher IQ people. These people come, love the content, stay, and repeat the cycle.

Countermeasures are just fighting this effect. It happened to Reddit, Fark, etc. One countermeasure is smart-flight evidenced by people fleeing to other subreddits like "TrueReddit" or making nearly identical subreddits "CanadianPolitics" vs "Canada". Or "LibertarianDebates" vs "Libertarian". It's like "white flight" only the division isn't racial, it's cognitive.

In my opinion HN suffers far less than it reasonably should, given its popularity and influence. Probably due to good attention, moderation, and direct involvement by pg. It's likely that when I joined HN I knew far less about the world and tech; upvoting the 500 mile email posting or a basic article on split testing. But I've grown and the community probably became a bit more mainstream and less intelligent.

The only community I haven't really seen it happen to so far is Less Wrong, but over there they are absolutely fanatical about keeping out poor discussion. I don't know if that is worth the effort.

To me, the best thing to do is to just leave once it gets bad enough and a better alternative pops up. Something else will come along. Maybe a secretive invite only HN, or something that customizes which articles you see based on what you upvote. The problem with the former is that secret societies are generally self-important and word always gets out (remember fight club anyone?). The problem with the latter is that it absolutely ruins a feeling of community. So those probably won't happen, it will probably just be a new community, much like this one, but with a clean slate.

So the general sense is that HN used to be great and a more open place. I agree. Here's an idea to prevent and reverse the decline of HN:

Set a large karma threshold for upvoting rights.

If you give a bunch of new users the right to upvote they'll just upvote each other based on their ideas on what makes a good community. There's no way to maintain or enforce the culture of the community when the new members can just bootstrap their own culture base with little to no input from the existing community.

If pg was inclined he could set this threshold, normalize/zero-out the karma scores for all accounts created after date X, and effectively go back in time to that date in terms of who has the power to set the tone and culture of HN.

Odd state? It certainly is... but it is only what... a year or two old now?

It seems to me that what is missing is a clear winner. Sure, competition from a number of different fronts is really great, but I think what made Java tick for a long time was JBoss and Spring. For Ruby, it is Rails. I'm sure Python has Django and others.

Clearly lots of people are working on it, but a powerhouse framework for NodeJS just hasn't surfaced quite yet. The OP's mention of security being bolted on as an afterthought really is something that makes me shudder. I can't imagine building a large scale public facing system without method level access control. I fear a whole new generation of injection type attacks against NodeJS frameworks.

While it is fun to play with all the shiny new NodeJS toys, I don't see why sticking with tried and true on the backend (take your pick of Python / Ruby / Java) is such a big deal. A lot of the cool features that are being touted in the NodeJS frameworks have been already done elsewhere for much longer.

For me, I've really successfully used NodeJS in one area where it really shines... scraping web pages... but that is simply because working with a jquery-like interface to the DOM, on the server side, is amazing.

In the end, it seems like if you're bootstrapping a company / product (like many of us here are) and trying to pick what to use for your base platform, the obvious choice is building features instead of building frameworks. This means you stick with the tried and true and hope that in the future, the shiny new toys mature a bit more before you go down that path.

Node.JS is a decent platform for developing on, if you know the caveats. You have to be very careful with the modules and frameworks you use -- as mentioned in the article, maturity of modules varies.

I know people that have had issues with socket.io and skipped it (and node.js) for their production needs. That said, my aha, gotta be careful, moment was when I was setting up a quick test, picked one of the http-digest auth modules, and had a bug -- actually a completely incorrect digest auth implementation (basic auth was fine). This was the second node.js module implementing digest auth that I used that had a bug that relatively simple testing would have found. (The other bug was around the caching/lifecycle of nonces.)

I plan on going back and submitting patches for both of these modules, but the lack of basic testing in two cases of a well known (and documented) feature reminded me that the platform is still in transition. (This is just one example of some issues I've run into)

Why I say you have to be careful? For the downsides, there are definite upsides. I needed a simple test https server w/ a rest API and serving a static file -- total lines of code, about 25. A great boon to prototyping.

Like any new framework, evaluate it in consideration with your needs.

You could potentially narrow it down a little bit by taking Express out of the equation. As far as I know, Express doesn't play on the browser. You could use Express to serve static content or a blog or an API but you would need to supplement it with something like Backbone or Ember on the client to build something like gmail or trello.

And while you could use Meteor (or, I'm sure, Derby) for a static website, that's obviously not what it's designed for. I've never tried it, though. I'm sure it would be a real beautiful experience.

One of the major reasons why OnLive struggled (and now failed) is because they launched their platform (20010) well after the launch of the XBox 360 (2005) and PS3 (2006).

Serious gamers, the early adopter market for OnLive, already had purchased an XBox 360 and/or PS3. Since OnLive, as far as I can tell, didn't have any compelling, exclusive titles, and provided a gaming experience that was inferior to alternatives, there was no reason for a serious gamer with a console to try (or switch to) this new platform.

OnLive needed to launch around the same time as the other consoles and deliver a superior experience, or an equivalent experience but at a lower price point (upfront and over time).

I don't have the answers, but severance pay sounds like a great way to protect against these kinds of assholes.

Why isn't Twitter charging for their API? dustyreagan.com

They do, and the price is $0.0001 per tweet.

Search rate limits through the normal API can be prohibitive for many use cases like news/brand monitoring. Or even citizen monitoring programs for local police. So they resort to datasift and gnip and are charged volume-based amounts on behalf of Twitter. And presumably, at the end of every month, a wire transfer goes out to Twitter.

Now that doesn't mean that twitter makes $1 per 10,000 tweets. A license to the tweet is required separately for each end user of those two platforms. So with 1000 datasift users accessing a particular tweet, Twitter is making $0.10 on it. The more people request that tweet the more money Twitter makes. Marginal cost = 0.

For more info, check out the Datasift FAQ's:

Or, why don't they just interleave ads into the streams and require developers to either display those ads or pay a CPM equivalent to hide them? It seems clear their main concern is around the home_timeline feed anyways, so weaving in their 'sponsored tweets' and requiring developers display them seems straight forward enough.

Unless it's a per/something charge the numbers wouldn't be significant. I would guess there's less than a thousand serious API developers.

It's because they want to build an advertising business and they don't want to compete with their developers. Twitter as a service is not the business they're in. They want direct access to their audience to increase their chances at monetization.

It makes perfect business sense, it just sucks.

Serious question: do people still have any remote desire to give the people behind Twitter money, after all they have pulled and shown themselves to be?

Because they ran the numbers. It wouldn't justify the valuation their investors demand, and it would be a distraction. Ads are their only hope. Draw your own conclusions.

I would assume that its in the works, but they already slapped developers in the face yesterday with new restrictions, if they added pricing plans on top of that, that would be inhumane and too much for developers to handle in on gulp.

Additionally with the pricing, its hard to get right. They won't be able to modify prices as they see fit after they announce them. So it seems like a logical progression: 1 restrict amount of data. 2 next, determine pricing

I don't think charging for API access will make them as much money as they want/need compared to being a media/ad company, that's probably the main reason. But, you're question did prompt me to ask my own:

Why doesn't Twitter rev-share their ads with 3rd party devs? http://gist.io/3383601

Not quite the same point - but similar thoughts: http://bit.ly/N9HnAD. What's really missing is a proper service contract. Not giving guarantees - or at best implicit ones will kill ecosystems.

NaNs Just Don't Get No Respect drdobbs.com

NaNs are annoying because, thanks to them, equality on floating point numbers is not an equivalence relation. In particular, NaN /= NaN.

This means that in Haskell, for example, you cannot really rely on the Eq class representing an equivalence relation. Code relying on the fact that x == x should be true for all x could not work as expected for floating point numbers.

I don't know if this has any practical ramifications in real code, but it certainly makes things less elegant and more complex than they have to be.

There are much worse thing than NaN's.

They are called denormals. These appear when dealing at the same time with lots of big numbers (very far away from 0) in operations with lots small numbers (close to 0).

In such cases the FPU (or whatever deals with fp numbers), switches to a format that could be very inefficient producing an order of magnitude slower operations.

For example when dealing with IIR filters in audio, your audio buffer might contain them. One of the solution is to have a white noise buffer somewhere (or couple of numbers) that are not denormalized and add with them - it would magically normalize again.

I'm not a guy dealing with "numerical stability" (usually these are physics, audio or any simualation engine programmers), but know this from simple experience.

The things this author likes about NaN are also properties of NULL in many environments (that NULL cannot be compared to NULL, that operating on NULL returns NULL, etc.); so while you might not see many languages default initializing things to NaN, you do see them default initializing things to NULL with similar effect.

I've gotten a bit pissed at the Microsoft C compiler for (1) having no standard way to generate NaN or Infinity and (2) having a good enough static analyzer that if you generate one by casting, it emits a warning saying that your arithmetic overflows.

Gee, thanks MSC. I didn't expect "x = INFINITY;" to overflow.

An alternative workaround to writing `float f = 0` in languages without NaN:

    float f;
bool thingIsFoo = condition1; // store the result…
if (thingIsFoo)
f = 7;
// ... code ...
if (thingIsFoo && condition2) // and explicitly depend on it later
++f;

But this causes an extra `&&` to be computed at runtime, so it seems NaNs are still better for this case.

You've written quite the interesting and informative article, and your logic as for why you initialize to NaN was perfectly clear.
