That is not enough, since you may still get stuck in a loop.

40 microwatts of power, to be precise. Compared to, say, 5V*1A=5W of typical phone charger, this is impractical by a large margin.

This could actually be caused by disk caching effects. Have you tried running cloc second time afterwards?

Well, that's why I always define RED(x) (for reduce modulo) as ((((x) % MOD) + MOD) % MOD). Quite useful in algorithmic competitions, which often ask you for answer modulo some prime.

From the listed words only two have immediately obvious Polish connotations (dźjada (grandpa), and dziadek is grandpa in Polish; śpjelik (sparrow), where śpiewać is "to sing"). Most words have German-ish sound to them, somewhat si

It's done so that the bits will compare the same way whether treated as float or int. (modulo NaNs and stuff)

The decreasing health bar looks like a really weird idea. I don't like to be forced into thinking fast, I prefer to make a clear point even if it takes longer.

Hm, if the example written on README is representative for current usage, then it surely changed a lot recently. I remember checking angr out a few months ago, and simply running a binary required a few dozens of, mostly boilerplate, code.

I'm pretty sure it doesn't matter whether the eneergy is stored in rotating body, or one moving in a straight line. Kinetic energy of rotation is 0.5 * I * w^2, or for that extreme case of "concrete ring" - 0.5 * m * r^2

It's really unrelated - it's more about the hash domain being rather small, i.e. 52. I would think that if you substitute the counting (go to card N+value) to proper hashing (go to card md5(value)%52) you would get the same, if no

It is possible to generate a lower bound, so it can be compared with usual numbers, like g_64 etc.

Actually, the mentioned GitList exploit hinges on yet another vulnerability: lack of distinction of command-line flags and arguments. Where user expected to put "normal" name (say a-zA-Z0-9), attacker actually supplied --flag=expl

I wouldn't be surprised if the future compilers would optimize it away as well, since ffast-math basicly makes NaN's equivalent to undefined behaviour.

It would be nice to divide the cooccurence count by counts of respective two headers, to get a sort of correlation. Now it's quite hard to see anything beyond "most popular things are paired with most popular things" which is

That is honestly a great idea for safe-ish deprecation in uninformed environment!

Presumably the stackexchange answer is what OP meant by it being an idiom.

Hmm, I guess someone would have thought of that, but this could probably be used for compressing images by reorienting the color axes so that one of them is perpendicular to this color plane, and then sending less information about that coo

There has been some malware that did just that - it was still possible to record the trace of instructions being executed along with the current instruction pointer to be able to reconstruct the binary quite well.

Can anyone explain why these two arrangements are not equivalent? They seem to both cause same phase shift and reflections, but the first one causes the photon to pass to the right, and the second - to split. https://imgur.com&#x

Vertical and horizontal here seem quite confusing. The absorptive polarizer with vertical lines drawn on it passes through photons passing through PBS, which game calls horizontal. So either the polarizer lines have negative logic (indicati

I can recommend one of his older flash games: KOHCTPYKTOP. Awesome, about making silicon-level transistors, gates, eventually chips...

Actually, they're not unit. When you type "abcd", then (without exiting insert mode) move left twice and type "xx" (resulting in "abxxcd"), then undoing once will leave you at "abcd".

Using fixed-point representation would allow using this compression method.
