It does do something similar... and more. IIUC, when unwinding on panic Rust does unlock the mutex, but it also "poisons" it so that a subsequent attempt to lock will return an error. This is because on panic all the code protecte

These are distinctions without a difference. Events replicated across several independent Matrix servers are not meaningfully different than events broadcast across independent clients in terms of observability or repudiation.

I don't know how it was approached for vitamin D, but it's all about the model they choose, which in the first instance is just something they pull out of thin air. For many water soluble vitamins and minerals the model is based o

AFAIU, cmov wasn't originally intended to be a guaranteed constant-time operation, Intel and AMD won't commit to keeping it constant-time in the future, but it just so happened that at one point it was implemented in constant-time

I've been using OpenBSD and PF for nearly 25 years (PF debuted December 2001). Over those years there have been syntax changes to pf.conf, but the most disruptive were early on, and I can't remember the last syntax change that eff

Iowa City is in Johnson County. A 2024 point-in-time count of the chronic homeless population--the highly visible population noticeably encountered in public spaces--in Johnson and Washington Counties combined is less than 200 people. See

Using the app a small soda at McDonald's is ~$1 ($1.14 near me, but that may include the SF soda tax). Less than $2 for a large for those beckoning diabetes. But soda is definitely cheaper elsewhere, and drinks, even soda, are usually

Have you used the app? You may need to use the app to get the McValue and similar lower-priced menu items. It's a brilliant price discrimination strategy.

Isn't that horribly out of date? More recent benchmarks elsewhere performed after some Go improvements show Go's C FFI having drastically lower overheard, by at least an order of magnitude, IIUC.

Until a few years ago, gccgo was well maintained and trailed the main Go compiler by 1 or 2 releases, depending on how the release schedules aligned. Having a second compiler was considered an important feature. Currently, the latest suppor

You're definitely correct. "#!" is reserved (see Rationale C.2.1), but not required, though it's described as "ubiquitous" (see Rationale C.1.7). "/bin/sh" isn't required either, but ar

It's already too exhausting to use for OOM, which is why Rust effectively punted on that from the very beginning. And the ironic thing is that anyhow::Error (or similar) seems poised to become idiomatic in Rust, which AFAIU always al
