Observation: I used to be a good hockey player, I have not practiced for 7 years so now I am bad. I also used to be a mathematics student at a high research university 18 years ago. Now I can no longer calculate (whole number) quartics in my head. I have also found that if I practice on IQ test related questions I achieve a higher IQ score in other IQ tests. Appreciate the article but would suggest "exercising" your intelligence can make you more intelligent in that field.

The TSA is apparently working on a fix for this sort of situation. I fly a lot, and recently on Southwest's booking system, I've started to see a form field for entering a special "I am not a terrorist" ID for people with coincidental identifying information. I don't know what it takes to get one, but I'll copy-paste the help file:

> The Redress # is a unique number issued by the DHS (Department of Homeland Security) that is used to facilitate passenger clearance for persons who have the same name as someone on the TSA (Transportation Security Administration) watch list.

China Blocks Avatar, Citing Restless Natives and James Cameron's Filthy Wealth
That is awesome, but what's the point in using batteries? It's just a sop to the environment that drastically limits the device's potential. The fact is that hydrocarbon fuel is still the best, highest density energy transport we have. Batteries are still weak and, especially for flight, awfully heavy.

Keep the electric motors but ditch the batteries and replace it with a small gas turbine generator. For the same weight, you could probably increase the flight time by a factor of 10, well beyond the willingness of most people to sit in that thing ...
You mean a train station? Yes I would.

Blowing up a plane/train/stadium/airport security waiting line/etc... is easy. The "real" risk I guess is people using jets full of fuel as flying missiles. However, post-9-11, no passengers will permit that use. Hijacking planes is over.

So the scenario you describe: getting onto a rapidly moving tube of metal with a couple hundred people who haven't gone through metal detectors or x-ray machines is exactly what happens every time I take the train. In fact, the lack of hour long security lines, having to remove my coat, belt, shoes, etc... is one of the reasons I strongly prefer the train.
Why not offer both?

B) should be disincentive to save using money, not a general disincentive to save itself. One could make investments in any other commodity whose value relative to other commodities stays constant or increases.

It is a somewhat unusual tax, in that your tax rate is based on what proportion of your assets are in dollars. Does someone know what the rate per year on dollar assets is and how to calculate it? You would need to know how much money the Fed prints in a year. Do they publish it or was that what auditing the fed was about?

Also for A), banks probably factor in inflation while setting the interest rate for a loan. So, the relevant variable, i guess, is unexpected inflation rather than the value of inflation itself. The debtor benefits only when the loan market makes low estimates.

Well, sorry to be so low-tech and all, but I tackle this problem in a couple of ways:

1. A (private) blog - person with the idea posts it, discussion happens in the comments. Pluses: Easy, clients for everything under the sun, easy mail gateways etc. Minuses: Someone has to cull the important stuff into an actionable request.

2. Our fault tracking system (homebrew but think bugzilla) - someone posts something (severity=wishlist) - you can close it if the discussion goes nowhere, or turn it into an active item if there is a conclusion. Pluses: very searchable, keeps all know-how about the project in one place. Minuses: Not the friendliest UI on the planet.

Seeing the words "startup" and "3-person team", my gut reaction is "don't ovethink this".
My first thought was that the company might be mismanaged.
It may be just going through growth pains.
The concept seems innocent enough. It sounds like what is needed is is a filter that keeps both sides of the discussion civil and warnings that "this post may be archived" with the appropriate reason so that no one is left guessing.

In my view, a good idea is generally the merging of one or more crappy ideas and so-so ideas into something that's workable. Because of this, I think you need to provide some mechanism for the cream to rise to the top. For the use case I'm envisioning, sharing ideas with a small number of users, I don't think a traditional voting system would work.

I think this could be an interesting space to employ some sort of visualization. I'm thinking something like http://www.archimuse.com/mw2006/papers/lowndes/lowndes-fig2-... for ideas.

Technically, I'd want something like this to be real time, shouldn't be too hard with ajax. There would also probably need to be supporting collaboration features, like chat.

Fish oil protects against cellular aging: study
I agree with this being reposted occasionally, as its lessons are fresh to newcomers.

Several of the other comments reference useful books on the topics, particularly on algorithms. One book that has a lot of important lessons about becoming a good programmer is Coders at Work.

One of the interviews is with Peter Norvig who tells about a bloggers failed attempt at solving sudoku. Peter's solution used a very novel approach to the problem that is non-obvious, and I would put this in the category of what you can learn from studying algorithms. They are not all about reducing computational complexity. Perhaps the other extreme example is an epic stack overflow answer that repeats many times that you can't use regular expressions to properly parse html. And this keeps coming up, it seems.

And I found the lessons in Coders at Work somewhat startling. I recommend it to new programmers and old programmers alike. It's not about the IDE, it's not about the language, it's not about the testing.
Find out if you have legal recourse. Assess the extent of the situation, and the clients involved. Place correct information on your website. Expose your competitor in whatever way necessary, especially for people cancelling with you.

You really don't understand how the topology of the Chinese political landscape has changed since 1989 - the "new" regime has brought wealth to tens of millions, and the country has seen dramatic modernization in the past decade and half. Not to mention the majority of China's young student population grew up completely divorced from the brutality of the Cultural Revolution. Something like Tiananmen Square simply cannot happen again today, even if it were allowed, simply because you wouldn't find enough supporters.

Keep in mind that when Tiananmen Square occurred, China was still a Soviet-style backwater with numerous spectacular failures at modernization. People were frustrated, oppressed, and starving. Now they're just oppressed - and that makes a huge difference.

The Chinese are nationalistic in the sense that they will defend their government, however imperfect they perceive it to be, because the alternative is treasonous (i.e., to side with foreign interests and ideology).

This is something Westerners find difficult to understand - but is very much rooted deeply in Chinese culture.

or every new vulnerability issued an OSVDB ID from January 1, 2010 through April 1, 2010, I will donate $0.50 (fiddy cents) of my own money to the OSVDB fundraiser. I challenge anyone who feels that OSVDB is a valuable resource to the security community to match my donation.

If people took him up on that, the Checkout account is going to have a surge of small donations, right? Oof. Aside from changing your usual pattern of behavior, which is always a risk with payment processing, small donations are often used to probe stolen credit cards to see if they are active or not. I could see a payment processing algorithm not liking that.

This would be less problematic if Google had customer service at least as good as Santa Claus'.

Sure, technically speaking Santa Claus doesn't exist. But if you post a letter to him, the Post Office puts it in with a big pile of mail, and parcels it out to dogooders. Many poor kids, as a consequence, do end up getting presents because they wrote to Santa Claus.

And how does this indicate that these hack attacks are sanctioned or originate from the Chinese government?

Nobody is saying the Chinese government isn't censor-happy and oppressive, but get a grip on yourself man. Talk to some Chinese - particularly the young ones - and you will find a population very truly eager to attack the West in whatever way they can. It's more than likely that a significant number of hacks coming out of China today are occurring out of people's own free will, not by the explicit order of the government.

Yet another Git tutorial. I've found that it's impossible to master Git by treating it like a black box- one _must_ understand how it works to truly understand it.
Test case: http://ejohn.org/files/json-parse/

Firefox 3.5: eval: 549 JSON.parse: 490
Safari 4: eval: 246 JSON.parse: 215
IE 8: eval: 1438 JSON.parse: 1031
Chrome: eval: 241 JSON.parse: 656

So yeah, a bit faster in Firefox and Safari, much much faster in IE 8 (the one that matters), and oddly slower in Chrome. I'll go out on a limb and blame their lax parsing (they support malformed strings).

In the end though the parsing is a distant second to the improved security: Guaranteeing that eval will never get touched in modern browsers is a huge win from a framework perspective.
Honestly, yes.

If someone wants to kill lots of people, they'll find a way. There are no metal detectors in a train station, but a bomb on a speeding subway car is just as lethal. There are no metal detectors in the mall, yet it'd be trivially easy for terrorists to fire off a couple shots in a mall and then mow down people with submachine guns at the exits. There used to be no metal detectors in schools, but then some teenagers found out it was trivially easy to kill lots of people there too.

The only reason I can think of why planes are any different is that a plane crash is much more sensational. "300 killed in mall shootout" would make headlines, but it doesn't inspire the same fear as "300 killed in downed airliner", particularly since it's virtually certain you'll die if your plane blows up in midair.
I offer both Paypal and Google Checkout because they're both wrapped in a consistent API by e-junkie. e-junkie doesn't support Amazon at the moment.

This reason was dismissed in the article:

You say it's a patent issue? Nothing's changed since the last time I walked that lonely road: I still have yet to see an Apple patent that covers the pinch-to-zoom gesture, and Palm, Microsoft, and a laundry list of other companies are all now using the move without consequence. Besides, it's freaking Google -- the same company that up and decided copyright law was broken and started scanning out of print books because it wanted to try something new. Even if there is some mythical Apple patent on pinch-to-zoom, Google is one of the few companies that has the financial and legal resources to get it invalidated -- and there's plenty of prior art out there that'll help it along the way.
Agreed. Legally, GA aircraft under visual flight rules must have at least 30 mins reserve so currently this thing wouldn't be allowed to fly!

Battery powered aircraft aren't completely impractical though. This Chinese electric 2 seater has a 40KW brushless electric motor, 400lbs of payload and up to 3 hours of endurance:
http://www.flyingmag.com/pilot-reports/lsa/sport/electrics-e...

The downside is it's slow (60mph), but if the engineering challenges for lithium-air batteries are ever solved you'd have a serious competitor to piston aircraft. Not to mention that electric engines are far more reliable than piston ICEs and you don't have to worry about fuel fires (just don't use Sony batteries ;-)
That's actually my point. "the Chinese are fiercely nationalistic" being too big of a blanket statement, since you are including the baby-boomers who protested all over the country in 1989, and older generations who spent their adulthood under Mao.
"Talk to some Chinese - particularly the young ones - and you will find a population very truly eager to attack the West in whatever way they can."

Why? I am genuinely curious. I can see why someone (say)in an Islamic society would want to attack the West, but why would a Chinese kid hate the West?
Google Gets 75% Of Paid Search Clicks & Dollars: Report
Holy cow - when you read this article right after this one:

http://reason.com/archives/2006/03/01/why-poor-countries-are...

it really blows your mind. I think the nay-sayers are missing the point of this article - it doesn't matter if you are sympathetic to the family. You have to remember that the higher paying job isn't creating 2x the economic output - her choice to take the lower paying job means that:

There is one fewer position making $120K

There is one more position making $60K

Now consider this: the $120K position is much more likely to be a management position, which, if done well, could create several $60K positions, lets say 3. This means that for the economy as a whole, there is one less $120K position and TWO fewer $60K positions.

In my opinion this is very scary.
It seems to be true in the US.

Choose the Water Pump Well Suited for Your Purpose
Well, The World is not running short of water. In fact, there is exactly the same amount of water as there was a million years ago. But the problem is soaring population and overwhelming industrialization, causing rivers to run dry across the world, resulting into shortage of water from the US to India and from Northern Nigeria to Central Asia. Therefore, water pump plays an important role in sufficing the demand of water consumption whether at home or on farms or in a company, and helps millions of people or families in Asia and Africa in watering their crops and slaking their thirst.
Did you actually say something, or just toss out a bunch of epithets that have nearly lost all meaning?

"300 killed in mall shootout" would be at least as big a story as an airline crash, probably dramatically bigger. The numbers killed in shootouts before the gunman is killed or otherwise disabled is usually in the single digits or double digits in extreme cases. As far as I know, there's never been a shooting incident in a first world nation with more than a few dozen killed or injured.

Normal Cryonics
Ask YC: [How] do you maintain a daily routine?
I usually waste a lot of my time on things that don't matter and as I'm getting older it's becoming a bigger priority for me to spend my time wisely. This year I resolved to get this part of my life under control. I think the best way to do it is to have a daily routine. When I tried to force a routine on myself, I realized there are three problems I need to solve:

- Sometimes I just don't want to do things in the scheduled order
- Sometimes other things take priority so I can't stick to schedule
- I cannot force myself to have a regular sleep schedule

I solved the first two problems in the following way. I divide the day into four hour chunks. The rule is, I can rearrange the tasks within a chunk any way I want, but they must be done within the designated chunk. If something prevents me from doing a task, when I get back on schedule I can drop any of the items within the chunk I'm currently in, but not in any other chunks. This way I have enough flexibility to do the things I want (or can), but enough structure that I don't lose track of things.

But I can't solve the third problem. My natural sleep schedule is very irregular. If I go to sleep at a given time, I can't fall asleep, and can't wake up in the morning. If I sleep when I want, my schedule becomes very irregular (I end up going to sleep on different times every day, usually my sleep time shifting later and later into the night until I flip over). Every time I was forced to keep a sleeping schedule (for a full-time job), I have been very unproductive and miserable.

This has been the biggest stumbling block to implementing a daily routine. Does anyone have a similar problem? How do you solve it? All the standard remedies (exercise, etc.) don't help me go to sleep at a regular time, and I don't want to force myself to sleep via OTC medication. Perhaps I can work around it? Or force a schedule somehow? How do you do it?
You have to assume Cameroon has as many clever, ambitious sociopaths as any other country. Why aren't they providing basic services? The article explains why long-term investment doesn't take place, but it doesn't explain why simple for-profit services don't crop up in competition with the official ones. For instance, if it costs too much to get a contract enforced legally, then there is a market for enforcing contracts illegally. This is obviously bad news for the government officials profiting from the legal enforcement of contracts -- unless they are the ones running the illegal service, and they structure it as an inferior, low-end alternative to their legal service. (Corrupt government officials have an advantage over the mafia: corrupt government officials don't have to worry about getting shut down by the authorities. They just have to share the loot with their superiors.)

The article also doesn't explain why government officials, even corrupt ones, fail to make cheap investments that pay off over a few years. For instance, a kleptocrat should want a reliable supply of clean water to ensure that the farmers are healthy enough to plant and harvest crops, so he can steal the profits. If an epidemic means the crops rot in the fields, that's money out of his pocket. Money is readily converted to power, via bribes, weapons, or propaganda. Losing money means losing power. Why wouldn't a kleptocrat spend money on sanitation, especially if that means getting good marks from foreign governments and NGOs and qualifying for more aid?
