Hilariously, the C standard requires this. C11 7.21.1.3: "The macros are [...] stderr, stdin, stdout which are expressions of type ‘‘pointer to FILE’’ that point to the FILE objects associated, respectively, with the standard error, in

Bluetooth devices often have problems when you're outside, in large rooms, etc. because there aren't any nearby walls for signals to bounce off of, so they're stuck with the lower SNR option of going straight through your bod

I've played around putting USB connectors directly on PCBs, and USB-A is way more lenient than USB-C. With USB-A, you can use basically any PCB thickness between the standard 1.6mm and 2.2mm, and it'll work well enough. USB-C&#x27

memset_s was added to C11 in an optional annex, and my understanding is that there are zero platforms that actually implement it. (Microsoft implemented an early draft of Annex K that doesn't actually include memset_s.)

You can get a Yotaphone 3 for $300 shipped from aliexpress, which is an Android phone with an OLED screen on one side, and an eInk screen on the other. The eInk screen is intended to be used with apps with custom support using a yota-specif

Because if you do that, you have to walk up the entire directory tree on every file operation.

posix_spawn is fine for that point in particular: it's encouraging the use of exec to regenerate state in servers that fork child processes as workers, so that accidentally leaking information from the child doesn't also leak it f

I think a more likely explanation is that HTTP/1.1 has been around forever (20 years!), while HTTP/2 is 4 years old, but about to be superseded.

And looking through the rest, two of them were "chemical leakage/fire in the cargo bay" and one of them was obvious pilot error ("fell off the runway").

That's generally true already, though? It's pretty trivial to make a lock unusable: just fill it with super glue.

There's an optimization that targets specifically this case: identical code folding. It's not safe in general, because the standard requires that the different versions must have different addresses, but if the compiler can prove

That's a bizarre conclusion to come to. The real motivation is that if you know apps are reflecting into your internal implementation details, and you want to make a change, you're stuck with a bunch of bad choices. 1. Break the a

Reference counting isn't inherently more predictable than tracing garbage collection. Take the example where your thread is the last one to deref a gigantic object graph. You're stuck holding the bag on traversing the entire graph
