I don't think it really makes sense to talk about "laws" for places like North Korea, as it's not a rule of law state.

I think they were all custom patterns specific to MacPaint and the Finder. The QuickDraw manual page 3-7 [1] says there are only five built-in patterns: "white", "black", "gray", "ltGray", and "d

There's no good way to verify that the browser hasn't been tampered with at the moment. Web Environment Integrity was an attempt, but that was withdrawn after outcry.

Widevine isn't available on 32-bit Linux, for one.

The browsers are open-source, so you could just make a custom build of the browser with a patch that saves the stream, which wouldn't require the analog hole.

Google has done this sort of thing before. My memory is fuzzy as to the details, but I think it was Native Client being allowlisted at the domain level to only work on Hangouts, or something like that.

I don't think it would let you do anything interesting you can't already do, as it's fairly easy to trigger exceptions in Java programs (OOM, for example).

But people get credit for scientific discoveries made before the technology to verify them existed all the time. Peter Higgs predicted the Higgs field in 1964 and won the Nobel Prize for it in 2013, after it was detected. The reason why the

Well, Democritus' theory of matter was closer to the truth than that of Aristotle, despite both being substantially wrong. Perhaps science would have progressed faster if Democritus' ideas had persisted up to the Renaissance inste

The main thing I can think of that would help here is the fact that Rust has stricter alignment requirements than C++ does. Any live reference can more or less be assumed to point to validly-aligned memory at all times, which isn't tru

Rust has that too, with nalgebra if you want arbitrary-sized tensors as scientific computing wants, or with glam and similar crates if your needs are more modest as in graphics. In all cases they're SIMD-accelerated.

I looked through the comments of the person you're replying to and they didn't say anything about Roe. There are all sorts of uncharitable assumptions I could make about what you might or might not believe based on your political

In many cases just using a hash table and sorting the keys is faster than using a B-tree anyway. I tried switching from a separate sort to a hash table in the Bevy game engine for binning of transparent objects recently and it was a big reg

We'll see how well it works for those languages. I have strong doubts that it'll be very usable in practice in for example Swift. That's because the boundary between "reference-anywhere" and aliasable-xor-mutable is

Other commenters have gone over many of the reasons why Go got popular, and I don't claim to know for certain, but in my view one important one is probably Rob Pike. He obviously has a well-known pedigree, he's very articulate, an

Stack overflow, which is a type of allocation failure, still aborts in Zig, so it's not that simple.

128-bit or 256-bit memsets via SIMD instructions are sufficient to saturate RAM bandwidth, so there wouldn't be much of a gain from having a dedicated instruction. (By the way, x86 does have a dedicated instruction--rep stosb--but comp

This is absolutely true. I remember Dan Luu [1] and patio11's [2] blog posts from 9 years ago and 13 years ago respectively, which were widely shared, arguing essentially that you should always prefer to join a FAANG. With FAANGs all d

Yeah, I agree. Regular H-M typechecking if you don't have subtyping is actually really fast. The problem is that subtyping makes it really complicated--in fact, IIRC, formally undecidable.

Automatic memory management is a synonym for garbage collection. Reference counting is a form of garbage collection.

The easiest ones to understand are the extortionists: "pay me and I'll go away" is not an uncommon tactic.
