If you really think you can: pitch. Don't just complain that other people are getting the money.

Thanks. I guess it's similar to the whole P != NP issue.

Has anyone heard if they managed to observe the effect of gravity on the particles? The Nature article was vague...

I remember hearing that this was one of the reasons why they needed to trap antimatter for observable lengths of time. To my understanding, they aren't completely sure yet which way antimatter "falls."

Both signify that the project was done quickly & may have bugs. Also, they aren't necessarily attempting to turn the project into a business, or even make money off the project.

It's a warning. They aren't looking for startup advice, they just want to show a (hopefully) helpful project that may have a few bugs.

I had the same experience (Droid 2), except it crashed before I could even accept the Root Permissions dialog, so I doubt I suffered any major damage. (The default permissions are more innocuous)

Using http://www.alloscomp.com/bitcoin/calculator.php :

On my computer (netbook running Chrome in Ubuntu), bitp.it clocks at 2.2khash/sec. Using this, I'll give 2000hash/sec/user as a conservative estimate.

If you had 1M daily visits, averaging about 1 minute of interaction (high, but assuming you have long-form content), you'd have 12000Mhash/day, or about 2.77Mhash/sec.

Plugging this in with current rates, this ends up being $0.08/day. For 1M views. This is about 3 orders of magnitude lower than just AdWords.

You might be able to do it with Java, but honestly that's even worse.

The hard part is that it is a security issue to record video from a webcam from a webpage. Flash lets you get around this.

When I started, I was thinking about using JS both "for the lulz" and because I'm comfortable enough with it that it wouldn't be a hindrance, like LOLCODE or Befunge.

I went with python instead because I assumed I'd need to squeeze as much efficiency as possible out of my programs.

For this round, these fears were completely unwarranted. All of the problems, except the second, were trivially O(n). (#2 wasn't worth optimizing, but it was possible)

Does anyone have experience with the next round? Is speed still not really an issue?

So fossil does have rebase?

Thanks for providing that. The biggest question I had was "Why?"

Even still, I don't completely understand his point (is he being rational?). Hasn't mtgox been invaluable in giving value to Bitcoins? Without it, it'd be harder to liquidate to hard currency, and the market value would be considerably lower.

He doesn't seem to be affiliated with a direct competitor to mtgox either, because that would also explain it...

EDIT: Yeah, I have a feeling he's being irrational:

  "The day before yesterday I was owed [owed] 100 BTC = $160 but today it $320 and it is too much for me. And it continues to grow simply because everyone is looking for people who cabal [can?] draw their own exchange rate on mtgox."

Although he has a completely valid point: the increased valuation of btc has increased his debts in real currency, he's approaching the problem in the wrong way. He technically is justified to a certain degree: mtgox has had this effect on btc. And now that it's down, I'm sure the exchange rate will fall.

In addition, it turns out that he runs btcex.com, a Russian competitor to mtgox.

When we did a stock market game in high school, we weren't allowed to use penny stocks.

I was so excited to find stocks that were doubling or tripling daily, only to realize how worthless it'd be in real life.

If anyone out there is a trader that works with penny stocks, I'd love to hear your insight. Is it possible to "game the system" by working with just a few (10-100) shares, instead of large holdings?

To be fair, the same happens in the stock market:

With bike locks, you're not looking for tensile strength, you need to resist shearing & shock loads.

Carbon fiber, for example, may be considered to be almost as strong as steel, but it breaks pretty easily when subjected to shear and shock forces, i.e. a bolt cutter.

Quickly skimming the article, graphene is only twice as strong as steel in this regard. Although this is still great, you have to be careful.

You can debate the validity of Crockford's claims all you want, but I think you're missing the point.

This exercise just shows how silly benchmarking is, especially when all the contenders are "sufficiently good."

To help improve the quality of comments, what if the OP's vote was weighted more than everyone else's? Their upvotes could be worth 3-5 instead of just 1 point.

An OP is motivated to keep their comment thread awesome: having better comments leads to more upvotes on the story. And, on a personal level, the OP would be less likely to upvote snark against their own story.

The obvious downside would be that the OP could effectively censor opposing ideas. However, I don't think this would happen that often: counterpoint comments generally do pretty well on their own, and would probably still rise to the top even without the OP's help. (Of course, the best OP's would recognize the benefit of discourse and promote these comments anyways... but not everyone is perfect)

I tried unity in 10.10 and found it to be cumbersome. I was shocked when they announced they were moving to it for 11.04.

But, it looks like it's undergone a few improvements.

(Strangely, I know,) I trust the people working on Ubuntu to make rational decisions. It looks like unity pulled through.

Thanks for addressing the issue. A lot of people are taking this as an opinion question: it's not.

Knuth has a large range of problems in his text. He scales them all by difficulty on a log scale from 0 to 50. Things rated 00-05 might be a basic facts or arithmetic (What is 6! ?).

A set of problems in the 20s would be a good chunk of work, each taking about 20-30 minutes. By the time you get to 40's, you're dealing with problems that you could write a paper on. In the introduction, he demands proof of Fermat's Last Theorem as an example for 50.

To the human or the printer?

This is pretty amazing & clever.

I wish the font file was available just to play with, even if it was a crippled version. Even though it's not a "full" typeface, I'm surprised he's not charging more. If it works as advertised, I'd gladly pay more than $15 for that bit of cleverness.

Agreed. A QR link would be nice.

"color camera group" isn't working for me, sadly.

I'd have to disagree too.

I just applied this year, and was incredibly pleased to get accepted. (woo!)

The thing is, my grades weren't stellar. Don't get me wrong, they were great, and I was ~15th in my class-- but people had better. Similarly, I only had a 2010 on the SATs after taking it twice. (To be fair though, I did have good AP scores)

Yet, with all that, I was the only one in my class to get in, out of 6. That group included the valedictorian, and saledictorian--heck, I was the only person not in the top 5%. And, I've been the first person to get in from my school in at least the last 7 years.

And, for what it's worth, my extracurriculars were relatively flat: only one language (French), no instruments, no athletics, no arts.

github_update.php wouldn't be linked to by any of your pages, so it shouldn't show up in the google index. You could also force it to accept some password as a GET parameter for a wee bit more security.

I agree though, this is still a really simple way to automate deployment.

If you're doing this sort of manipulation, it's not like you can't afford the extra cycles.

I set up a jsperf to do some benchmarking:

If you can help out by running the tests, it'll be great to compare browsers.

This isn't exactly the perfect tool for the job, but it's close enough.

> Could you link to a Twitter account, e-mail subscription of some sort? There's a 95% chance that I forget everything you just wrote after I close this tab, unless Techcrunch, Daring Fireball, and HN shower you with attention.

I think the "threads" link works pretty well for this.

>A "report" button for individual comments would also be great.

Isn't this what flagging is for?

I assume they're doing this because of some government restriction on photographing the city? Otherwise, I can't imagine that this kind of effort could be profitable...

Can you indicate where your company is located? (This really does not sound like a telecommuting job)

Edit: Looks like SF.

Is there a reason that Apple needs to keep creating its own proprietary connections/protocols?

Worse, they keep changing.

I've also spent some time on http://hacker.org

Rather than focus on a specific "answer," you instead write algorithms to solve various flash games based on NP-complete/hard problems. Its interesting since there's always ways to improve. You can start out with a brute-force solver, but as the levels scale your program won't.

They also recently added a "challenges" section, which is more about specific coding tasks. Those are also pretty fun & scale well.

And yes, despite the domain name & poor design, it's actually a pretty serious site. The same guy also did http://goproblems.com/ , which is cool if you're into Go (the board game, not the lang).
