Is the JS file somehow being embedded into index.html on the server side? If not, how do you expect this to be atomic when the user’s browser is making two separate requests (with an arbitrary delay between them)?

This is how Rust’s mutexes work as well - albeit using RAII rather than a callback, but with the same fundamental innovation of putting the data inside the mutex object. I’ve used it in my C++ code as well; it’s a great pattern.

Makes me wonder how many other lurking type confusion bugs there are. KASAN only found this one because it happened to produce an out-of-bounds access (I guess pci_dev is larger than whatever struct the pointer really pointed to); it can’t

That's right. Indeed, if the optimization is implemented properly it should have no observable behavioral difference except for performance (better in some cases, worse in others) which is not really something POSIX concerns itself wi

As does macOS. Linux also supports it (zram), though I think most distros don’t enable it by default (could be wrong).

If you click the link in the blog post with the text “firewalls need adjustments to let 'QUIC' traffic through”, it seems like there is some of the latter as well. Well, not holding off on allowing it through their network, per s

Personally I don't think the analogy holds up; the situations are too different. Computer security contends with securing systems against people who are assumed to be hostile. AI alignment research seeks to prevent systems from becom

Because it’s fine-tuning an existing 7B-parameter language model, not training from scratch.

Note that macOS now has three “apps” to view your passwords, three different UIs for the same database. There’s Keychain Access, there’s the Passwords section of System Settings, and there’s the Passwords section of Safari preferences (w

You don't need a larger mutex for fairness. For recursive locking, maybe. But most mutexes aren't recursive. That's one of the big problems with pthread mutexes: they try to pack too much functionality into a single type.

The kinds of programs that were putting in entirely nonstandard paths (~/app.config), or paths specific to macOS or Windows, are still doing that. But when it comes to a 'well-behaved' Unix program, there used to be one place

But what makes an abstraction 'right'? I would say it's if it makes the program easier to make correct, or easier to write, or easier to understand, or easier to maintain, or ideally some combination of all of those. But ea

Even with an arena allocator, the indirection is likely to increase cache misses, especially when the array element type is something small like an integer. It’s possible to implement something like smallvec without the branch by having it

Do you know if any of them support GPTQ [1], either end-to-end or just by importing weights that were previously quantized with GPTQ? Apparently GPTQ provides a significant quality boost “for free”. I haven’t had time to look into this in

But Bob was right that the problem was algorithmic. Checking whether a string ends with a prefix of an emoji abbreviation is a task that could easily be done in a microsecond. It’s apparently taking 100 milliseconds, which is 100,000 tim

Swift’s choice has the advantage of visually unifying the two cases where text in a string literal is interpreted as something other than the text itself. One is backslash escapes like \n and \\. The other is string interpolation.

Rust code tends to rely extensively on generic containers to encapsulate various safety properties. That will be hard to replicate in C. Still, I’d like to see how it works out in practice. But where’s the code? Judging by the website fo
