I asked the blog's author and he said hits do interrupt scripts. Aside from that, more complex scripts intended for higher difficulty have explicit conditional branches after moves to allow for blocking and counters. The triple firebal

Even with an embarrassingly parallel problem, you need to have enough compute work per memory access to achieve anything like full utilization. Suppose you're doing a pairwise multiplication of two huge arrays. That's as embarrass

If you mean the kind of people who punch Richard Spencer in the face, I'm not sure what that has to do with anything in this discussion. And if you want people to engage with you seriously, post under a real account.

I read the Jolly Roger's Cookbook (and many other BBS text files) as a teenager and used it to make thermite with my chemistry teacher in the 10th grade. And reading Phrack and old virus magazines like 40HEX did more to engender intell

Yeah, I should have mentioned that. Whereas shebang notation is understood by the executable loader, not the shell.

Rather than using shebang notation for running C source files, which as noted leads to code which isn't legal input to a normal C compiler, there is a standard trick to please both the shell and the C compiler: #if 0 /bi

Hopefully someone finds it helpful! I should also note that the picture I painted is most applicable to block ciphers, but it does apply mutatis mutandis to hash functions and pseudo-random generators. With hashing, you have an inherent los

The FCC legally regulates use of the electromagnetic spectrum. For example, FCC conformance for EMI in electronic devices is not some optional stamp of approval for the benefit of discerning consumers. It's a legal requirement.

The earliest Moldbug screeds I came across, nearly ten years ago, were accusations of elitism towards academic computer science, and he's continued espousing that view ever since, interleaved with his other political writings. An early

Here's a little gem that I don't see mentioned on there. For bit unpacking in C, the natural inclination is to shift out the least significant bit with something like this: u1 getbit() { u1 lsb = x & 1; x >>= 1; re

I'd agree if we weren't talking about a company renowned for having among the highest base salaries in the business. Engineers who go to Netflix have a lot of other options and should know what culture they're joining.

> The general rule of thumb for stock market returns is a 7% real return. Over the 15-year period from 1966 to 1981, the real annualized rate of return in the stock market was -0.4% because of high inflation. You need to look at 20 to 30
