Here's something I tried running (index generation):

map = function (docID, text) {
var results = [];
var words = text.split(' ');
for(var index in words) {
results.push({key: words[index], value: docID});
}

this.done = true;
this.results = results;
}

reduce = function (word, docIDs) {
self.postMessage("starting reduce for distributed relevance-sorted index generation");
var counts = {};
var results = [];
for(var index in docIDs) {
var docID = docIDs[index];
if(docID in counts) {
counts[docID]++;
} else {
counts[docID] = 1;
results.push(docID);
}
}

results.sort(function(a, b) {return counts[b] - counts[a];})

this.done = true;
this.results = results;
}

data = {1: "the quick brown fox jumps over the lazy dog while the slow yellow fox stumbles around the yard", 2: "on the ning nang nong where the cows go bong and the monkeys all say boo", 3: "lions and tigers and bears oh my , i suppose next we'll see monkeys and maybe a fox"}

Didn't seem to work, but maybe I did something wrong.
The failure has not been prevented, it has merely been postponed to a point at which it will be vastly worse.

This is a fundamental misunderstanding of economics that politicians tend to have. You can't spend money and change history, all you can do is let the errors f the past be worked out via natural processes, like bankruptcy. If we had liquidated all those fraudulent securities we would have a stronger economy than we do by damaging the rest of the economy in order to perpetuate the fiction that those securities were not fraudulent.

The money used to support these bog use housing securities was taken out of the economy, and that act damaged it more than letting banks fail.

It, notably, also did not free up the credit markets which remain seized. In this case the market was not tricked by a political action that did not address the fundamental issues.

Hopefully, Khan, and the people he inspires, can work towards a solution to the larger problem in making education accessible to everyone: while the resources for education are readily available to anyone who can get to a public library, the culture of the least educated people often prohibits self-improvement.

I don't mean this to be a prejudiced statement, I understand there are prejudices and nuances, but I live in a very blue collar neighborhood, and I hang out in the library and interact with the middle school and high school students here. The percentage of people in my town who would feel comfortable admitting an interest in watching a Khan Academy video is very low.

Height is not the most important factor in swimming, but out of 10 people, only one was under 6' and he is still taller than average. Now look at something like size of hands and they are going to stand out even more. Practice may be able to get an average person to the 90th percentile in most things but once you start talking about 99.99% DNA becomes extremely important.
Yep. Sometime, even people with a lot of practice in writing thought provoking blog posts lose their "game".

Adams will "win" his next post I'm sure. He practiced a lot, but he also has this elusive thing called talent. He just mistook it for practice this time around.

The performance problems originate in the design of your trace compiler, not in static vs. dynamic dispatch. Some suggestions:

* The interpreter should have a fast profiling mode (hashed counting of loop backedges) and a slower recording mode (for every instruction call the recorder first, then execute the instruction). Either implement it twice (it's small enough), use a modifiable dispatch table and intercept the dispatch in recording mode (indirect threading), or compute branch offsets relative to a base (change the base to switch modes).

* Don't record traces for a long time and then compile everything together. Do it incrementally:

- Detect a hot loop, switch into recording mode, record a trace, compile it, attach it to the bytecode, switch to profiling mode (which may call your compiled trace right away).

- Make the side exits branch to external stubs which do more profiling (one counter per exit). Start recording hot traces and continue until it hits an existing trace or abort if it hits an uncompiled loop.

- If you completely control the machine code generation (i.e. not with LLVM), you can attach the side traces to their branch points by patching the machine code. Otherwise you may need to use indirections or recompile clusters of the graph after a certain threshold is reached.

- Region selection has a major impact on performance, so be prepared to carefully tune the heuristics.

* Sink all stores, especially updates of the virtual PC, data pointers etc. Don't count on the optimizer to do this for you.

* Due to the nature of the source language you may need to preprocess the IR or you need to teach the optimizer some additional tricks.

- E.g. the loop [-] should really be turned into 'data[0] = 0'.

- Or the loop [->>>+<<<] should be turned into 'data[3] += data[0]; data[0] = 0'.

- It's unlikely any optimizer handles all of these cases, since no sane programmer would write such code ... oh, wait. :-)
I think this is the crux of the matter. Sure "I Like <something>" may lead into "I want to receive more information about <something>" but it's not necessarily a '===' relationship it's not even an 'implies' relationship. More like "x implies y sometimes."
Ask HN: Review my startup - DuringConstruction.com
Hi HN! I just released the first iteration of a new service that provides nice coming soon pages. The idea is to replace the hideous GoDaddy ad filled pages with something nice looking and useful.

The average person cannot be Scott Adams either.

The point is that you could make the comparison to the top 1% (that's what a pro athlete is) of anything and point out that innate talent and hard work is what got them there. He uses athletes because it's easy - most of us don't have that ability, and somehow feel this isn't fair.

Most Hacker News readers, though, are on the high end of the IQ scale. I sure as hell don't have to explain to you how (generally) our innate ability to understand computers better than the average person somehow means we have to work less...

I have to agree that it's against Facebook's own interests. If they let random sites spam away, then pretty soon it will turn into MySpace, and competitors will eat its lunch.

The error is to assume that krugman is an expert and that people who disagree with him are unqualified.

This is because much of what passes for economics is rationalizations given with a political purpose, and the primary propagandist in that effort is krugman. Remember. This is the guy who advocated that we should have a housing bubble, the denied we were in one, etc.

He is, to be sincere, and embarrassment to the science of economics.... But he is the government designated esparto and so there are millions of people who believe his nonsense because they don't know better and trust the experts.

Actually, the science of economics isn't that hard, nor is it complicated enough to need ot listen to an expert. You can teach yourself. Economics in one lesson is the tittle of a book that im sure you will find enlightening.... And it was written by an expert.

I don't think people are more apt to downvote than in the past. But there are a lot more voters. Plus I recently removed the -4 threshold on comment scores and instead merely never display a number lower than -4. So downvoted comments now cost more karma.

I think you misread the stats by a bit. From the article:

"Together, these 3.6 million workers with wages at or below the minimum made up 4.9 percent of all hourly-paid workers."

"Although workers under age 25 represented only about one-fifth of hourly-paid workers, they made up about half of those paid the Federal minimum wage or less."

"Among employed teenagers paid by the hour, nearly 19 percent earned the minimum wage or less, compared with about 3 percent of workers age 25 and over."

I also really like how the birds flew in and I thought that it's one of the things people always said couldn't be done without Java or Flash plugins. By that metric html5 really is a success.

Although I wouldn't say there's a best part. The experience were running smoothly on my system, so it all the pieces added up to something more. Tough the draw/write were a bit out of place, but I can imagine that they wouldn't want to leave it out because of the way stuff you made (the drawing) interacted with the automated stuff (the birds).

I always run my browser un-maximised at only about 1/3 of my monitor's size, so I like how the web-experience came out of the browser, but like others, fearing a bit that this might become more normal. I already hate how youtube videos are auto-starting; imagine some tab in the background spawning multiple windows simply because they are trying to make an experience.

So if nothing else this shows that we don't need Flash even for flashy experience-oriented art sites :)

Thanks PG. I have previously considered YC, unfortunately the cost of living far exceeds the amount of capital YC could provide initially.

Looking around the industry lately it seems that you can't do a startup unless you're fresh out of college with not a care in the world.

On the other hand, if you actually have industry experience (even if you are under 30), you can't "drop out" of "real life" because of implicit responsibilities (socially - such as dependents, and financially - such as rent/bills).
Austrians correctly predicted:
The great depression
The rise of Naziism
The decline of the soviet union, and it's fall, and why it would fall, based on economic principles about 50 years before it happened.
The appearance of the housing bubble in 2000, along with the prediction that it would burst and take down major banks.

In my lifetime, when krugman and politicians have been saying one thing, and austrians have been saying another, consistently the austrians have turned out to be right. Meanwhile the politicians in question are no longer in office, and krugman contradicts himself regularly.

Plus, if you will read some austrian writings you will find the are retry straightforward and comprehensible.

Unfortunately, on topics like this, wikipedia has a very strong left bias, so it is best to go to the source.

I think this was the original idea. But now Apple is a direct competitor (iAds), and clearly not shy about blocking competitors from their platform. Microsoft (or whoever) could do the same as well. It makes sense for Google to control and promote their own platform for their services (see Chrome and Chrome OS), as an insurance policy if nothing else.

I think this is a great idea and useful service and I would definitely use it. However, I think the main page could use some redesign. In my opinion, the appearance appears 'dirty'. The example site looks great and has good vibrant color choices but your website doesn't reflect this style. At first I thought the snapshot of your example site was an ad. Maybe want to fix that? Once you have more examples you can have a gallery of them so people can get an idea of what they want and of what you can do. Layout/placement/content seems fine, it's just the color and theme of your website brings me down. I feel like things need to pop. Hope this helps.

I think monetary policy is the primary axis upon which these two schools are separated. Chicago is under sway Keynes when it comets minatory policy-- but note this is not the same as keynsianism which is a modern political theory that ignores the repercussions of easement that Keynes warned about.

Austrians are pretty much hard money. There are some interesting comments made by rothbards and Friedman about each other ot illustrate the split.

The schools reach similar conclusions on a number of issues, though.

You already accepted they are separate, I'm just trying to add flavor here, not win a point.
At the time, I mocked Verizon for branding their Android devices as "Droid," but now I think it's a little brilliant. Companies like Dell and anyone else can release crap, and it won't damage Verizon's brand, since most of the public doesn't know that they have the same OS underneath.

> I presume that 5% luck, is luck in the instance of the game, not luck being gifted at it

I think you're right, because he also says, "playing a best of five series eliminates most of the luck." Playing best of five wouldn't eliminate the luck of being gifted, because that kind of luck would give you an advantage in each game. Luck in the instance of the game probably averages out over many games.

> The only thing you can probably be confident of is that with good practice you will improve. But no guarantee that if you do more hours of practice than another person that you will be better.

Absolutely. I remember when I was learning to play guitar, my book talked about a guitarist who became very proficient very quickly, because his father was adamant about him only practicing the right things. I, on the other hand, always wanted to jump in and start playing Hendrix or Zeppelin. I didn't want to play scales for hours on end, so even after a few years I was only marginally better.

This is exactly what I'm talking about. I only mentioned Krugman because he's often vilified by the same people who get wound up in economics threads.

People on the Keynes side of the equation also get wound up over mentions of Chicago School stuff.

That said, it is weird that you're saying Krugman is some sort of government designated expert when almost every column he writes is critical of the economic policies being made in Washington. He disagreed with the size of the stimulus (he wanted it to be larger), he thinks the Fed has its head in the sand, etc. . . .

And as far as Paul Krugman being an expert, I find it very strange that you would disagree with that. You might disagree with his policy positions but he is most definitely an expert in the field.

Notice I never made any judgements about policy itself. My remark was that people who are not qualified in economics dismiss people who are right out of hand: Krugman is just a good example because he really seems to rile up libertarians and Austrians.

Personally my favourite opposing viewpoints to Krugman are made by Tyler Cowan, I like to read them both. Anyway, it's not my objective to get into a policy discussion, I was interested more in the meta-observation which you so handily provided reinforcement for.
