He wasn't doing arbitrage. He was investing in companies in that he thought were going up in stock price. Clearly he was researching different companies, and finding ones that he thought would do well in the future, but most people hadn't noticed yet. Then he would buy into them, and wait for them to hit it big, then cash out. This is not arbitrage, this is straight out investing.

I've never seen such a concise description of my academic life.
Your first point is a good one, and looking back was presumably the basis for pg's disagreement. And as long as there is no serious problem with posts by brand new accounts that alone is likely a good enough reason to say I'm wrong.

Your second point could be fixed by allowing users to create pseudo-accounts that don't visibly link back to their main accounts. Although as I think about that now that would only work until lawyers got involved, so not at all on serious issues.

On second thought I concede to your points.
The Paleo diet is not exactly mainstream science, so I don't think that's neither here nor there in relation to this article.

This seems to be a good summary of what refined carbs are: http://lowcarbdiets.about.com/od/glossary/g/refinedcarbohdra...

Or, in short: All sugar including corn suryp, white grains (rice, wheat), starch, and grains in the form of flakes, puffs and so forth.
Until it runs out of glycogen and turns to beta-oxidation...

On the plus side, you'll be really sensitive to insulin when you do get some carbs into your system again :) And hey, I just read an article that said lowering insulin levels is the key to the longevity gains resulting from caloric restriction.
What's the evidence that you're thinking of that HFCS is particularly bad for you? Sugar is bad for you no matter what form it takes.

Emotiv is such a trainwreck; part vaporware, part straight old-fashioned fail.

They're literally years behind schedule with a product that doesn't work (see http://killerprojects.wordpress.com/2010/04/10/arduino-assis...) and is based on a theoretically flawed operating principle. They were a great PR machine for about a year a long time ago and since then have had one fiasco after another.
I've just put a web app into production and one of my client's associates is driving me nuts with his "shrug reports" ('A bug report with no error message or “how to reproduce” steps and only a vague description of the problem. Usually contains the phrase "doesn’t work."'). So I really enjoyed this list.
I hate "me too" posts, but when I saw what you wrote I really did want to give you more than one "upvote". I'm a mathematics (and computer science) major at a large, middle of the road university and I can say my experience has been exactly this. I gave my full rant in another comment ( http://news.ycombinator.com/item?id=1312043 ). Basically, real mathematics takes a lot of mental resources, so in order to appeal to the masses universities have to make the material mind-numbingly stupid. Remember: it would be unacceptable to large corporations if only 1% of the current engineering graduates were graduating, regardless of how much smarter that smaller group would be.

> Of course most smart people I knew would more or less blow off the homework and just ace the tests, and thus they would often end up getting a B- even though they probably understood the material better than anyone else.

My Calculus II class graded mostly on the stupid homework (from James Stewart's book, no less) and attendance!

Unless you care enough to work hard in highschool and have enough money to go to a school like MIT, "higher" education is a huge joke.

Many gifted children fail at the commonly accepted academic standards.

The value of the commonly accepted academic standards is debatable.

Given my IQ, I could be considered a failure because I stopped with a Masters instead of finishing a PhD. I might be considered a huge failure because I've devoted myself to raising my son (and learning lots of interesting things along the way) rather than to a technical career. But I'm not a failure, I'm simply succeeding on a different path from the expected one.
This is interesting stuff, but I do wish they didn't show the solutions immediately after the question. The Prolog and Lisp versions do this better, by providing a link to the solution.

I was surprised not to find "heisenbug". It's on Wikipedia, along with other families of bugs.

No, I don't think that's true. Grains in general are troublesome (there are some worse than others, so that for instance bran won't kill you and flax is downright good for you [but yech]), but this isn't some fad about how bleached flour is particularly bad for you. Foods consisting primarily of flour are in general not going to be particularly healthy.

Here's a link:

http://www.health.harvard.edu/newsweek/Glycemic_index_and_gl...

'carbocation posted a link to an Excel spreadsheet of GI listings for lots of foods, too.

You'll find that the lists aren't simply about demonizing Coca Cola and Wonder Bread.
It's not as simple as avoiding refined carbohydrates. Rice, baked potatoes, watermellon, dates, and parsnips all have a very high (>90) glycemic index, while some refined carbohydrates such as whole wheat bread and pasta have medium to low GI (<70).
It's good to see the poor stability of the Facebook API starting to get some more public attention. Much of the downtime that top Facebook apps have is due to the platform itself and developers are often powerless to do anything about it. It's disappointing to see that platform stability is still bad even though Facebook has been at this for nearly 3 years.

SHA-224, SHA-256, SHA-384 and SHA-512

is any one better than another? for instance, the way AES-256 and -192 are considered potentially less secure than 128, at least according to something i read from Schneier a while back.
According to the spreadsheet 'carbocation posted from the National Cancer Institute, white rice has almost as bad a glycemic impact as white bread.
True, but reading a longer work on a topic can also reveal a lot of things you didn't know you didn't know.
Fructose actually has a very low glycemic index, about 20 compared to 100 for glucose and about 68 for sucrose. HFCS has a glycemic index of about 62.

If you want to follow a low glycemic index diet, it's much more important to avoid potatoes, white bread, white flour and rice than HFCS
Posting 1 comment on 10,000 sites to see which are vulnerable lets you concentrate the bulk of your efforts on the best targets. There's no URL in the post which may mean they are creating a list to hand-spam later on. It's a lot harder for filters to catch hand written text and if a random comment gets through the likelihood that a hand written one will is high.

So maybe out of 10,000 sites they find 1,000 that are good targets and then have their third-world employees go to town working at 10x the rate. Not a bad return.

It's sort of like burglars cruising through a neighborhood on multiple nights to see who has the lights off.
No, but they don't care. They're just using Mother's Day as an excuse to do some drug-dealer marketing--giving a little bit away for free to try to make you a consistent customer.
Are there studies that study the effect of exercise on the badness of sugar? Do bread, pasta, potatoes, etc. qualify as sugar? (looking for an excuse to keep eating these things)

Not really. MSFT basically destroyed an existing competitor (netscape) by putting IE in every copy of windows. They used their monopoly in desktop OS to get a near monopoly in web browsers. They also did fun things like make OEM's pay for windows licenses for every machine sold or would raise the price of licenses OEM's did want. So... you bought a machine to put Linux on, you still paid for windows.

Apple on the other hand, makes a phone that has a controlled market for applications. There isn't a pre-existing competitor there that they are destroying, so it's not really the same.

The success of other smartphones actually works in Apple's favor here. There's nothing wrong with Apple having a monopoly on Apple products. What is wrong would be having a monopoly on all smartphones, then abusing that monopoly to corner the smartphone web browser market.

What Apple is doing, is pretty much the same thing that all of the game console makers do. You can't easily get software for a Wii that Nintendo doesn't approve of... Same with Sony, and, of course, MSFT on the XBOX. [yes, you can buy a Wii game at walmart... just not one that Nintendo doesn't want to license.]
How rapidly can you place upward into more advanced classes (presumably only for math majors) at your university?

I always guessed it had to do with spamfilters: Previous approved posters will get auto approved on next posts, I assume (for some filters).

I might be considered a huge failure because I've devoted myself to raising my son (and learning lots of interesting things along the way) rather than to a technical career.

Not by me. I've been following much the same path. Learning more about my children's interests has helped prepare me for a more challenging career now that my children are growing up.
Thats a good point. It'd be interesting to see someone do the calculations to see how the energy levels required for building and running electronics (in addition to the destruction of areas that possess various necessary minerals) compares with the amount of energy required to do stuff manually.

The argument about wood as a good renewable building material is a good one, however, not getting the "bulk" and not getting most are two completely different things, and the world really needs to get on a renewable system fast.

Also, while in a lot of places you will find reference to there being zero net change in the amount of trees being cut down, the fact of the matter is that a lot of old growth forest is still being destroyed.

This reasonable looking article: http://ecology.com/features/paperchase/, says that 9% of wood for paper is taken from old growth forests.

Here is another place that lays it out in a graph: http://www.greenfacts.org/en/forests/figtableboxes/figure-2-.... http://www.greenfacts.org/en/forests/.

After reading the IAMA more closely, I think that I was wrong in my initial assessment of him, he is doing it because he want the exercise, and is still participating in more "real" projects on the side in a less stressful setting, which is cool. My real point was that it would be really easy to do something like this, thinking that it would be great, and then realizing some time later that you were part of something that you really didn't like on principle.

THIS SWORD RUINED MY LIFE, DON'T BUY IT. My life was great, I had a beautiful wife and a successful self-owned business. Then last week, a short portly gentleman with a short necktie barged into my slaughterhouse business and demanded I kneel before him...I declined. He unsheathed the Cold Steel and began destroying all of my﻿ meat in a whirlwind of fury, my business was gone. He turned to my wife and struck a gallant pose with Cold Steel, she couldn't resist him and fell in love and left me. (via youtube)
But Google does a lot of trafic shaping as well: If you Wget a video, you see the first bytes stream in really quickly, after which the speed goes down. No need for your ISP to do this as well.
I assume Google tweaks it so your buffer doesn't get empty, but also not too full: if you decide the close the video, the buffer is wasted (which, on Youtube's scale, is a LOT of data).
Telstra's subsidiary in New Zealand was also at the bottom of all rankings, but this week they installed the Google cache boxes to mask the issue.

YouTube now hits 3-5Mbps for me. At start of playback it appears to burst a chunk of video, and as it gets close to needing to buffer, it bursts another chunk.

Maybe the Australian parent should look into it, it helps a lot.

I can actually watch 720p and higher without having to pause and come back in 10 minutes.
It depends on the classes, actually. They do "clepping out" on a per-professor basis. But trust me, I'm looking into that.

EDIT: I even sat in on an upper-level programming languages course, and the most advanced thing you learned (from what I gathered) was a bit of Common Lisp. I hate to sound like an arrogant ass, but for the entire lecture I was thinking "Is there something wrong with me? I learned this in highschool!"
My favorite YouTube comment:

THIS SWORD MADE MY LIFE, BUY IT. My life was a mess I had no wife and no job and obviously no self-self owned business. About a week a guy I, a short portly gentleman, wore a short necktie and barged into a slaughterhouse business demanding that the owner kneel before me.. he declined. In a fury I unsheathed my Cold Steel Great Sword destroyed all of the meat ruining the mans business. His wife, a fine woman, was next to him so I struck a gallant pose and she immediately fell in love with me.
I'm still trying to figure out just how much some smart students' educational choices are constrained by family income.

Traveling light works great when you're young and childless. It gets a lot harder to be "light" when you have a diaper bag and a milk pump.

There are always degrees--there are lighter ways to travel with children (being willing to carry soiled cloth diapers versus carrying a volume of one-time-use diapers), but kids often get in the way of the illusion of not needing money or possessions.
Yoda conditions, like ternary operators[1], are perfectly readable if you have more than a week's experience working with them IMO.

Actually, I was thinking more of the public's attitude towards offshore drilling, really. Recollection bias will make it seem to be more common than it actually is, and more people will frown upon it.

From a purely rational standpoint, you're right. People won't see that as long as nothing goes wrong, though. It would be good to see responsible parties informing the public of what they've learned, and how this sort of thing will be avoided in the future.

The thesis here ("Initially promising children often underperform") might be correct, but there is nothing in the methodology that supports this point.

What troubles me about the submitted article (which I submitted after seeing it recommended by a local friend on a statewide email list in my state) is that the lead paragraph includes the statement "According to a 2003 study, a mere 40 percent of gifted children will complete an undergraduate degree or pursue graduate studies. The rest drop out." I see contact information for the University of Montreal press officer (for follow-up on this press release), but I don't see any citation to anyone's study, and it is not at all clear who constituted the 2003 study population. Perhaps that was a very unrepresentative group of gifted students and this result will never be replicated. I'm not at all sure what is going on here based on the reported statement. This drives me back to Peter Norvig's advice on reading research reports

http://norvig.com/experiment-design.html

and suggests much better research is needed on this issue.
Ask HN: A good tutorial for C#/.Net?
At work, our main legacy app is written in C#/.Net - so far, my main experience has been working in Ruby/Java. Working in .Net has been good so far but I haven't been able to find a book/tutorial that tied a lot of "essential concepts" together really well. E.g. how does the Global Assembly Cache (GAC) tie into your application, things of that nature.

Any recommendations?
There are attacks against AES-256 that haven't been extended back to smaller key sizes.

If you're typing the letters S-H-A-2-5-6 into your code, you're doing something wrong; you should be using GPG, or Keyczar, or some other high-level interface that has chosen the algorithms for you and deployed them safely.

That said, the standard practice today in new software that will be audited is SHA256.

All this web page says is "don't use SHA1".
I get this a lot from dedicated ebook readers: "I don't care about formatting and design in ebooks!"

Gary Taubes' Good Calories, Bad Calories is a great book that examines the science behind low-carb diets and attacks low-fat diets as completely lacking scientific support and being essentially the biggest public health disaster of the 20th century.
My personal perspective: I am a Kaiser member (California) and I love it. It is extremely simple to deal with: if I ever feel sick, I show up at a Kaiser facility and pay a $10 co-pay. If I need tests, I walk down the hall and pay a $20 co-pay. There is no billing, no headache, no mess. Everything is in one facility and integrated. The doctors, nurses, and NPs seem competent, if somewhat busy.

That said, I've heard that people with rare and specialized conditions have a harder time navigating the Kaiser system, but I'm not sure that it's any worse with other healthcare systems.

Overall, it has made me a believer in the HMO model when properly executed. And it appears that it takes complete integration for it to work right: the joy of Kaiser is having everything in one building and managed through one system.

I think I agree with you for the most part. I'm giving them the benefit of the doubt until about 3 months have passed. If after three months I still feel that they've done something wrong then I'll start to believe it. The reason why I've listed elsewhere in this thread, when change to something familiar happens we will have a 'knee jerk' response that is conservative, even if in the long term we'll change our minds.
Google has a good track record. In most cases Google is actually too conservative for my tastes. Some of these new defaults have been in Google Labs for years. The changes to GMail when Buzz was launched is the only big screw-up I can remember and they addressed that quickly enough.
While it's nice that fructose doesn't raise blood sugar like the other monosaccharides, you need to keep in mind that fructose gets preferential uptake treatment by the liver. If you eat too much of a food that contains fructose, you can overwhelm your liver into producing triglycerides (see http://www.ncbi.nlm.nih.gov/pmc/articles/PMC302539). While we're not entirely sure that triglycerides themselves are responsible for ill health, having elevated levels has been linked to all sorts of chronic diseases.
At first I was wondering if people would object to this being posted here (I'm not such a person btw), but then I realized, this really is HACKer news.

Also, the boots full of meat really put me off too :)
I don't agree that the reason people think an e-book is worth less is overvaluating the cost of paper and ink. People feel that an e-book is worth less than a paper book because the physical experience of handling a book is worth more than the experience of reading a book on a computer or e-reader screen. The e-book has other advantages, but we're not used to those and thus it feels to many people like they're getting less.

Also, I believe that the author under-estimates other values inherent in a physical book, such as the ability to lend it to someone else, at least as long as DRM is the norm.
and if you lose your job, you'll actually be conditioned to want to get right back into the same limited housing options because you won't be paying full price.

and the irony is that you are paying full price, just not paying all of it directly. you the taxpayer are paying the difference between the employer paid option and the open market option.

but that's all hidden from you, because, if nothing else, this system thrives on deception.
