It's not a few dozen lines of code because of, among other things, the case in which one thread allocates a lot of memory that is then sent to another thread to be freed. This actually happens more frequently than you'd think, bec

On macOS iMessage is scriptable in various ways (both officially supported and unsupported), so the security argument doesn't hold water to me. It's a business decision.

Don't use a fork and don't customize your user.js. It is exceedingly unlikely that excess power consumption is caused by anything you can easily tweak. Instead report issues to Mozilla.

Don't use Fasterfox. It tweaks many settings that frequently result in performance regressions. The default networking-related settings are set the way they are for a reason.

The parent comment isn't saying that locating in Trump Tower indicates support for anything. What it's saying is that the vast majority of people will think of the former president every time they walk into a building named Trum

But you have to use operator overloading to use smart pointers. This isn't a pedantic nerd snipe; the point is that operator overloading really is indispensable in certain contexts.

Seconding this. Nikita has been a fantastic help in reviewing my LLVM contributions over the past couple of years.

I disagree with the ergonomics being poor. C++ SSE intrinsics are significantly worse, with ugly underscores and names that are hard to remember.

"Not having C++ anywhere in the stack" is not a goal of the C language or any major implementation I know of. The two major OSS C compilers, GCC and Clang, are both C++ codebases.

The author isn't saying margin collapse should go away entirely (though, having had to implement it, it sure is tempting to get rid of the feature). Rather, they're talking about the situation in which a div is empty and has top

One of the biggest problems with Mercurial is that they took a long time for histedit to become a usable workflow. I speculate (without any evidence, so this could be entirely wrong) that this is because many Mercurial contributors preferre

You've successfully formulated the reasoning behind the legal "public figure" [1] standard from first principles. Elon Musk, especially when speaking in his capacity as owner of X, is unquestionably a public figure in a way t

This is a good point. Null pointers are the billion-dollar mistake, but the real billion-dollar mistake is having "zero values" in your language. In addition to the problems with null pointers, zero values make loose constructor s

Yes, Firefox did the right thing here, and it's arguably a bug in Chromium that it exposed SAPI to the Web. As a general rule, you shouldn't expose platform-specific APIs to Web content, if for no other reason than to avoid Web co

I doubt that a hypothetical version of Rust that avoided monomorphization would compile any faster. I remember doing experiments to that effect in the early days and found that monomorphization wasn't really slower. That's because

Interesting, I thought about this in the past but assumed it would be too slow. Do you know of any titles that have shipped with that technique?

They use the same compiler backend and you can generate pretty much any LLVM IR you want with Rust. You can argue about the performance characteristics of the kind of code the language encourages you to write, but a blanket statement like t

I suspect that it's two things: (1) the relatively good support for Wasm in Rust; (2) the Cargo ecosystem. In the case of Ruffle, the combination of the two seems particularly effective.

Debating what the "core issue" is may be an interesting philosophical debate, but at the end of the day, using a memory-safe language would have prevented this issue from being exploitable.
