I'll be interested to hear the thoughts behind the "Probably Avoid" recommendation on DSA and EC signatures. They're both attractive in some situations because they produce much shorter signatures than RSA. The recommendation for AES-256 o

Your != proposed change likely results in a branch, which is what we're trying to avoid. The ^ version is fine, but the original subtraction is too as long as they're unsigned.

It reminds me of the way that aircraft avionics are sometimes made more reliable - they build N complete controllers from scratch, to the same requirements, then use a voting system to discard the output from a controller that is malfunctio

It says it only supports C89, and the largest type that C89 specifies is `long`, with a minimum size of 32 bits. So I presume it just doesn't provide `long long` (or `[u]int64_t`)

Gold's value isn't based in its industrial uses, though; in fact, the faith-based pricing of it inhibits industrial uses. Real-estate on the Moon is also divisible and un-manufacturable, but no-one seems to be arguing that we should base a

Your "every k steps" operation executes N / k times, which isn't O(k) so I don't think it meets the requirements given.

The Chinese leadership, like the leadership of every country, is a band of old men. Old men who know they won't be around to see the worst consequences of global warming, but consider that they might well be around long enough to hang from

This is why it's a really good idea to have the unit tests written by someone who didn't write the code being tested.

Making the hardware map a single thread of control onto parallel computations on separate cores is a hard problem - one that hasn't been solved yet. If you reckon you can solve it, you should definitely be able to get rich from it.

Exactly the point - that call takes 11 parameters, many of which are complex structures themselves. Compare that to: pid_t fork(void); int execve(const char filename, char const argv[], char *const envp[]); The idea is to have several si

Aye. This way, we can control a large number of aspects of the child's environment in which execve() is called, without having to have execve() do all that work for us. We can open files, change the session id, reparent the process to ini

That's actually how fork() is implemented today on Linux, too - the clone() system call can be used to implement either processes or threads (by specifying exactly what is to be copied and what is to be shared), and modern versions of glibc
