From what I've read, one key issue was that some exchanges stopped trading or updating certain prices for a few minutes, which led to other exchanges making trades in isolation instead of tying them into the larger market. With just a few more "sell at any price" than "buy at a reasonable price" orders for a given stock on a given exchange, and with no tie-in to other buy orders from other places, the "buy at a ridiculously low price" orders that many traders leave in place just to take advantage of algorithmic glitches of this nature were triggered.

It's like being at a car auction with a robot auctioneer and putting in a one-penny starting bid, and then the robot's sensors malfunction so he can't see any more bids. He'll declare you the auction winner, but that result doesn't reflect the car's actual value and will almost definitely be canceled.
This site should be a static page that just quotes whoever said this:

"How can a team of artists work for years on a project and have the result not be art?"
The company behind the book got in touch with me and suggested that this might let me buy a PDF to use:

I'm not seeing any obvious sign of that but am currently investigating.
Exactly. He doesn't seem to realize everything is new and exciting when you first get it. We bought a pool table in my house and used it like crazy for about 6 months, and then barely touched it for 5 years. I can see the iPad being fun and useful for some things, and the price isn't terrible when you compare that some netbooks are going for close to that, but the comment "I'll never buy a real computer ever again!" is a bit ridiculous.

Even his daughter that wants one for college wouldn't want it as her ONLY computer. It would be a pain to write a paper on, or make a spreadsheet for your lab report, or probably even a powerpoint presentation. I had a tablet in college and almost never used it.
It's bloody depressing. Think of what you could do with all that gear...

it must be lovely to live with such strong self-delusion.
normally I find the comments on HN to be well thought and reasoned...

I believe he made clear what he expects on this forum.
The single biggest change is the top ads are now barely delineated, this whole redesign is a cash and "stickiness" grab.
>Good thing nobody ever had a complicated spread sheet, a document on letterhead for the office or a small programming job to do!

At home? Most people don't.

Every computer I've watched my parents buy over the past 15 years, they buy Microsoft Office as a reflex response. When I visited for the holidays and helped migrate them to their iMac, I noticed the number of Word and Excel documents they had accumulated over this period.

About 40.

Outside of school assignments, what need does a child have for a productivity suite? Close to zero, and even then, 98% of what they do for writing assignments can be accomplished by a simple typewriter or standalone electronic word processor. Programming? Don't get me started...

My sister bought a 15" MacBook Pro over the holidays, and a copy of Office. She doesn't work on documents, just logs in to Outlook Web Access and maybe reviews something sent to her. She does the real work, well, at work. Aside from occasionally loading new photos into iPhoto after one of her 2 yearly vacations, it's a $1700 web browser and media consumption device.

My non-IT friends? The same. Webmail. Facebook. Funny pictures of cats.

The computer in the traditional sense is becoming a lot more niche. Why? It's what people want.

It's like the new 2011 Mustangs are hitting dealer lots. I want the V8, a 6-speed, the performance axle and the good brakes. Out of the dozens of Ford dealers in a 100 mile radius, only ONE dealer has manual transmissions. The only reason that dealer has them is because it's Bob "Win on Sunday, Sell on Monday" Tasca -- a car enthusiast, catering to other enthusiasts.

We're computer enthusiasts. The virtues of SSDs are just as foreign as the virtues of powersliding to someone who's, frankly, just not that interested and just wants to get something done inexpensively and with a minimum of fuss that doesn't involve a debugger or heel-toeing.
guys, this looks awesome. it's obvious that a ton of work went into it. congrats!

i really like the change of direction, too -- it's becoming more and more obvious that betting your company on flash is not a good long-term strategic move.

but if nothing else, i'm happy that it makes my reading experience so much better :)
Booyah, a Palo Alto based company, is looking for an all-star Web Developer. Check out the link below for the details!

http://blog.booyah.com/booyah/2010/04/web-developer-needed.h...
From the article "Exelon was just one of a number of stocks that produced bizarre, and presumably garbled, market quotes during the “Flash Crash” of the afternoon."

(Emphasis mine)
It would only be a morale nightmare if the decisions were made randomly (or for political reasons), and not based on performance/job fit. My experience is that people tend to view letting underperformers go as a positive. It's far more damaging to morale to keep the underperformers around.
Wow, this is seriously awesome. I always avoided Scribd because I could never just download the PDF, but with HTML5 view + fullscreen mode I am happy. Now time to overtake Slideshare... ;P
Perhaps, but I've always been a little ahead of the curve. ;)

Seriously though, it'd be impossible for anyone outside facebook to provide any hard proof of their utilization. From the outside, it's all speculation.

What is your estimate on FB's future? Here's my prediction: Facebook users revolt. Another social network evolves, or an existing one becomes the dominant, perhaps orkut or ning, or foursquare. I'm not sure I'm just an observer, but I think within the two to three year mark, facebook will be about as popular among the "in crowd" as myspace is right now and we'll be talking about some other network in 10 posts to the front page of HN.

Facebook will try to get someone to buy them for maybe a couple hundred million. Tons of investors will be angry. Mark will be declared the egomaniac who didn't know when to quit and he'll struggle for the rest of his life to find another successful project.
Facebook is Dying
This just looks like someone found an exploit that could crash prices faster than naked shorts and bounce them back again once the necessary shares had been acquired. It would be very interesting to see who acquired shares at the zero and low prices and what they were doing before that - I doubt they left too many clues though. Perhaps if we look at who bought a country today that might help.
What a horrible interview process and post-interview discussion. Even if I had gotten the job, after watching that self-important and vague, irrational driven reasoning process I'd promptly turn it down.
The Relationship Between Facebook and Privacy: It's Really Complicated

It is hard to overcharge because you can always lower the price if you don't get enough sales, but if you start out low it is hard to raise without pissing off later customers. Considering it is a really useful app primarily aimed at business users $50 sounds low to me.
It's a good thing the iPad does have excellent battery life because in our family, it's being used almost all day long. The other night I completely lost my wife and daughter for hours as they played Plants vs Zombies together way past bedtime. My five year old has already requested one for her birthday.
Spot on. Ipads around my home and office seem to mutiply like rabbits. Most people can't articulate why they need one but the little things like competently clearing your email from bed or sitting through 7 hrs of airport travel hell and still have 50% battery are exceptional.
I am sorry to comment harshly but this is most WTF article which i have ever read!

To quote the Author
"""
Specifically, a large number of developers seem to think that they have the right to make software for the iPhone (or for anything else) in Flash, or in another high-level environment of their choosing. Literally, the right, not just the convenience or the opportunity. And many of them are quite churlish about the matter
"""

I mean come on!
Some one write a translator which converts code from one language to another! And stupid tactics are being used by Apple to stop it!

Does this person does not know about the Turing Completeness of programming languages??? It does not matter which programming language you use as long as it is Turing complete!

The article goes on to make dubious arguments about computational creativity on different platforms which make totally no sense!
Thanks for the well-thought questions. Being as the web is all about content, there are many players and there is plenty of overlap. We do want to create a place where people want to publish their essays, poems, notes, etc.

I too am a developer, and it is sometimes easy to get caught up in the technological aspects of interesting projects such as this, our latest. I do feel, however, that we have/are creating a platform people want to use.

Here's an anecdote about some value I feel we began providing recently: I got to work on a little project we called Readcasting a few weeks ago. It basically allows people to passively or actively share what they are reading. A day or so ago, one of the ladies in marketing circulated an article[1] about how the social aspects of Scribd (to a large extent Readcasting) has helped an author gain a great deal of exposure. I thought that was pretty nice to hear. It's always a pleasure to see that people use and like the things you build, but it also pointed directly at the purpose of Scribd - to create a platform that benefits the people who publish on it.

1. http://www.huffingtonpost.com/kate-rados/where-marketing-mis...
Excellent! I was just wishing someone made something like this the other day after feeling that using Latex on Windows 7 was a subpar experience to what I was used to on Ubuntu.
These are all great questions - thanks for giving me an opportunity to clarify. Let me try to explain.

Regarding 1)
We've done site surveys in the past to try to understand why people upload to Scribd. Every time we do it, we find that the #1 reason is: "Scribd gets me readers". Not "it hosts my docs for free", or "I like the display format", or whatever. Readers is what they want, and so we have worked very hard to maximize the number of readers we can get them.

I think file hosting sites are great, and Scribd is not attempting to replace them, they just serve a different purpose. If you want to share a file with a few friends, a file hosting site makes a lot of sense. But if you want to build an audience of strangers, posting on Scribd gives you a surprisingly good change of doing that.

If you don't believe me, try posting some doc you've written on Scribd. You will probably be surprised by the number of random people bumping into your document brought by related doc traffic, Scribd community traffic, search engines, Facebook, Twitter, our mobile apps, and all the other ways we make Scribd content discoverable.

re 2)
Absolutely. Scribd isn't trying to be a content discovery site - other sites do a great job of that. Rather, if we've done our job right, then when you bump into interesting links on Digg and Reddit, some fraction of them will happen to be hosted on Scribd. Now that we've launched the HTML5 reader, you will hopefully enjoy clicking over to Scribd to read the document that Reddit surfaced for you.

Re making Scribd a "high-end" brand - I think that is a terrific idea. Creating that kind of brand is not easy, but it can be extremely valuable.
The #1 problem I have with scribd is that you appear to be unapologetic content thieves.

Take, as an example, the [scribd] links that HN generates automatically. That's your earliest investor automatically stealing and rehosting content in violation of both your TOS and the law, and you do nothing about it.

You must be aware of it, but you don't stop it. That certainly gives the appearance that you don't care that you make a large portion of your money by screwing over rightsholders.

Truly, I believe the world is a worse place because your business exists, and that if you shuttered your business today the gains would vastly outweigh the losses experienced by all. I understand that the DMCA allows you to operate with impunity, but legal doesn't mean ethical. In this case, it's just abuse of a loophole in a poorly written law.

This is my entirely honest opinion. I continue to hope you'll close down scribd, or at a minimum engage in a MASSIVE rethinking of how you deal with copyrighted content. I know this won't be a popular opinion, but I simply can't understand how [scribd] links are anything other than a tacit admission that your real business is the monetization of pirated documents.
Two distinct responses, so two separate replies. First, the same old argument that has nothing to do with the OP:

> especially if my app doesn't depend on anything special that one platform provides.

Why is it in Apple's best interests for your app to run on iPhone? What competitive advantage do they lose if your app--which doesn't depend on anything special--runs on android, palm, and blackberry but not on iphone?
It was already a PDF/DOC/etc. aggregator -- that's always been their entire business model.

What's new is that they're demonstrating that they care about people actually being able to read the content.
Turing-completeness of programming languages is pretty irrelevant: different languages make some kinds of things easier or harder, support some idioms and discourage others, tend towards certain kinds of programming, etc. That's why programming in Haskell, Ruby, C, and asm are not all identical in practice, even though in theory any program written in one could be written in any other. And yes, they do support different kinds of computational creativity.
Could is the important word here. Even with all the technology they have now they don’t do much. Getting rid of some technology and replacing some with simpler technology seems like a efficient thing to do.

There will still be dirt cheap fully featured PCs, so if anyone in the family ever feels like they not only could but will want to do more they can to that. That’s hardly depressing.
Accenture went from 41 to 0.04, back to 41 on twice the previous day's volume. I guess once the computers stop,
the markets get thin really fast.
Two distinct responses, so two separate replies. Second, the point of the post is that it is a benefit to the programmer to learn and use multiple languages. I get the feeling that the Apple row is a McGuffin, a way to introduce his thoughts on programming education.
You're welcome, Jacques.

IT shows perfectly why technology does not brings intelligence.
You can give them the best hardware and still they wont become next Google or Facebook founders or use it in any other productive endevour!
Seriously most of the human race does not deserves the power of computing!

They wont lolcats on "magical devices!"
long live America!
What a waste!
Reddit also has considerable more uptime and speed issues than digg. I like Reddit, but it is slow and recently often experiencing issues.
You sir are correct.

There is a bit of distorted thinking and mob mentality going on here. It's beginning to seem like every other week the tech community is out with torches and pitchforks. Kind of a "burn the witch!" thing going on.

I use FB, but I think it's model is about as evil as it can get, and that was before this happened. I'll be happy when we have some options.

I don't mind everybody piling on, but it is interesting to note the vast amount of inconsistencies in people's thinking. For me, I can handle the app stuff -- it's the use of my friends to make me act against my own interests that I find truly diabolic.
I didn't compare any of those examples to all of WW2, but rather you rour example of the 100k japanese interned during WW2. And despite that, suffering can't be gauged merely on the number of people killed.

You said: "Have you seen any witches burned recently? Have 100K Japanese people on the west coast been put into camps recently?"

And my response was to indicate that tragedies like those are still happening in modern times, for very much the same reasons.

"Forced labor worldwide? Slavery was legal in the US 150 years ago. Now it is not -- in fact, we just elected a black president."

You response seems to have little to do with my point. Forced labor is a worldwide problem. Reciting US history to me does little to discredit that. I'd like to know what Obama has done recently to stop the sex trafficking of girls from Eastern Europe or Southeast Asia.
My Nexus One seems to be missing a number of symbols because I saw a few square boxes. Otherwise an amazing achievement - a very usable mobile PDF viewer.

Anyone on an iPad/iPhone/Pre able to see every symbol on that paper?
Yeah i know they are different but when one has created a bridge between two languages, disallowing it for some non nonsensical reasons of "computational creativity" seems utterly stupid to me!
> He doesn't seem to realize everything is new and exciting when you first get it.

True, but there's also the possibility of a device either truly replacing previous technology or creating a whole new niche. For example, my iPhone was cool and fun when I first got it and I had been a Treo owner for years, so smartphones aren't new to my life. However, today, my iPhone is quite integrated into my life, way beyond just a cool new gadget.

I know for my family, the iPad fills almost all needs, such that we really only need iPads plus my own laptop which I can share with my wife and kids on the few odd occasions when they actually need to use a computer. I can definitely see that being the trend in other families.
Social Privacy Using Shared Knowledge
They are representative of the state of the world in that we still allow them to go on. If you think your hands are clean in any of that, then you are sorely mistaken.
Been wanting to play with Go but have yet to find a reason to code with it (being the type of coder who prefers to learn as he works). I guess I could write a library . . or go completely nuts and write a python implementation!
I love this idea. But it looks like for the moment, their 'compile' feature (set to 'default compiler') on ec2 is overloaded.
Really? So what's a publishing deal (distribution, some marketing, storefront, updating, &c) that has a better split then that?

I can guarantee you you won't find one for video games, at least.

Also, Android market has the same split. So does Palm's, Nokia's, and WinMob. Blackberry is 80/20.
Yeah, my guess is the 2nd also. The author of the post also has a background being interested in how differences in computational platforms affect what's produced on them. He has a whole book on how, when looking at "Atari games", it's not irrelevant that they were made on an Atari, and to really understand them requires understanding the Atari VCS programming model and hardware: http://www.bogost.com/books/video_computer_system.shtml

My high-level read of this post is a worry that that's becoming no longer true: the way that programming and hardware differences made Atari VCS, arcade, Commodore 64, and Apple II software each have its own distinctive style, might not be replicated in the present day, as Android, iPhone, and Blackberry apps all look like the same munge of identical apps compiled through some compatibility layer, and not really taking advantage of anything distinctive about each platform.
If it was an error, this is the wrong way to think about things. People who had short positions with GTC limits deep into the range traveled also could have made a bundle. The limit orders would have executed damn fast.

If this was an error though, Nasdaq (or I assume the clearing houses more precisely) are doing exactly the right thing. Imagine if they didn't reverse the orders and it came out that a wall street firm happened to make 10% on a huge position today. With the way things are, someone would break out the guillotine.

(Edit: Bias Note: I've had May Put options at 118 on SPY since Tuesday. I did not close my position, so feel free to accuse me of being jealous ;))
Please don't take this as being too critical, but I used my bread-maker every other day for 2 weeks after buying it. I can't remember the last time I got it out the cupboard.
What if i wrote a haskell to C++ converter and Microsoft (Wait Apple already did that) banned it because it only wants you to use OO programmin!! Also we know that Haskell/Lisp/Scheme are more suited toward certain applications!

Still do you agree that Haskell or Scheme is "bad" for IPAd just because it has a touch interface???
"A language that doesn't affect the way you think about programming, is not worth knowing." --Alan Perlis

I think this is the point of the OP, obscured somewhat by the discussion of 3.3.1 (IMO). While in theory everything is possible with every language, each "worthwhile" language affects the way you think about programming. Idiomatic Ruby makes you think about extremely late binding of behaviour. Flash and Processing make you think about drawing on a canvas (in different ways!). Idiomatic Lisp makes you think about programs as data. And so forth.

I think it matters very much which programming language you use, and I can demonstrate this. Let's have a programming contest. You may choose what we are to build. You may pick a domain in which you are comfortable. I may choose the language you use, provided it is Turing-complete.
A similar incident happened in Tokyo Stock Exchange a few years ago.

(...) on December 8, 2005 in which a Mizuho dealer mistakenly sold 610,000 shares in J-Com, a recruitment business, at 1 yen instead of selling 1 share at 610,000 yen.

The dealer, understood to be a 24-year old woman, immediately realised the mistake but was unable to cancel the trade because of a technical glitch in the exchange's trading system. Mizuho was forced to buy back the shares, leaving it with a 40.7 billion yen loss, prompting the firm to cancel year-end bonuses for all staff in the trading unit.

Note in Japan executed trades cannot be canceled (though in this case the trader was supposed to be able to cancel the orders before they were executed). Many brokers made a big profit. Some institutional investors too. One particular day trader became quite rich and to this day is a sort of legend on internet trading boards.
My iPad is still getting about 3-4 hours use a day - and it still, 30 days later, is pretty popular at parties, restaurants, etc... I'll check back in a couple months. New Apps (PopSci, Time, Penultimate, Sketch, Alice, etc...) keep my interest, mostly. Though Videos, Field Runners, PvZ, Safari, Kindle, WSJ, Mirror's Edge, Marvel, GoodReader, and Email are in pretty much constant rotation.

It's unclear to me if I'll still be as addicted in six months, but the form factor certainly is appealing.

One thing nobody talk about the battery life - It's _not_ 10 hours. It's 10 Hours of _use_. Used on and off, I'll go close to three days before needing to plugin. That's very nice.
Oh I'm not complaining that trades are being canceled. My thing is that if it hadn't been an error, then I would have been in a good position by selling early. But since it seems to have been an error, then my selling early disqualifies me from getting the order canceled, so I lose out for making what seemed like the right move at the time.
Nice. I also recommend the Watexy bot for Google Wave if you want to try some form of collaborative mathematics.
