If you want to have it much faster, use transparent PNG image for saturation-value rectangle instead of drawing everything in canvas and then just color its background property according to hue. Long ago I needed color picker, so I did re

Now you made me blush. At least with such short competitions your involvement is limited. Constraints work both ways: deadlines are liberating when they pass.

Even more so then. No matter which solution you pick for "rich web" experience (Java, Flash, HTML5, Unity), somebody is going to get subpar performance. Also, Java applets are canonical example of RIA: http://en.wikipedia.org/wiki/Rich_Int

Works very smooth for me (Win 7, Firefox 3.6.8). <rant> As a sidenote, this difference of experience highlights a big problem with rich web applications. You get so high variance in performance depending on a particular comb

Fascinating, it's amazing what people can do under severe constraints. I just finished my second JS10K entry (also a game, but much simpler) in about the same total time (though spread over more days). I found the hardest part was to balanc

Try this: http://en.akinator.com/ It's pretty good at figuring out who you think about (fictional or real) just by asking yes/no questions.

This wouldn't work anyways. Especially for datamining-is-our-core-competency company like Google it should be relatively trivial to match your old and new identity. There are plenty of ways how to do it. There are only 7 billion people, y

LaTeX's default look is very tired, especially if you spent some time in academia. Every CV/paper/thesis looks the same. LaTeX is a good crutch if you are complete design antitalent, but the same thing that prevents you from shooting yourse

They kind of have to be sideline businesses. Expensive niche job boards work well only if you already have a valuable community and reputation. They can't be created out of thin air, you need to have "main business" to piggyback upon. Most

With some handwaving it could be about $82.5K (computation spread over 1 year) or $125K (computation done in 1 month). total cost was 35 CPU years (Intel Nehalem, 4-core, 2.8GHz) 1 EC2 compute unit is about 1 GHz Xeon let's assume 1

This also works for SQL commands: use SELECT before UPDATE/DELETE with the same WHERE clause for sanity check.

More likely it looks like bias favoring cross-disciplinary research. Different fields have different typical citations rates. Biological sciences tend to have orders of magnitude higher impact factors than other fields [1]. So, for example,

Ah, yes. For the lower bound, we can estimate just the price of fuel (no plane amortization, crew and ground personnel costs, airport taxes, etc). This seems to be currently about $54K per flight (London to San Francisco). 747 burns abo

Very rough estimate based on passenger ticket prices gives about $20 per GB/s. SF <-> London is about $1,200 for return ticket (Kayak) 747 can have about 400 passengers bandwidth is 12 TB/s (from the post) 400*1200/2 = $2

So this explains Palantir's massive funding [1]. Even in a normal environment what they do is lucrative, but in a current state of affairs this must be a gold mine. [1] http://www.crunchbase.com/company/palantir-technologies

If the interview is adaptive (increasing difficulty till you can't handle it anymore), strongest candidates may end up feeling it went terrible, while weak candidates may feel it went very well (not being aware they were culled out early).

With lotteries there is a strong selection bias. Rational people usually don't indulge in lotteries. Among lottery winners there will be disproportionally more people who are going to be really bad with money management.
