Does anyone know where _BitInt(N) is specified for the WASM ABI, if it's specified at all? Clang can compile it, but when it comes to long term compat I'd rather it be written in a standard somewhere.
As _BitInt implies, I'm concerned about C23 here.

Подводные камни устройства карты видимости в СУБД PostgreSQL
Карта видимости - это достаточно простой механизм в СУБД PostgreSQL, но даже он имеет множество интересных тайн, если погрузиться в детали реализации. В этой статье мы выясним: 1. Какие особенности есть у механизма сбрасывания и установки бита полной видимости. 2. Как Index only scan использует бит полной видимости. 3. Зачем записывать информацию об изменении карты видимости в WAL. 4. Каким образом карта видимости участвует в оптимизации предвыборки Bitmap scan. 5. Зачем механизму оценки селективности нужна карта видимости.

Yesterday, I finished :python: support for #birch. Today, it will be :c_language:.
I like this second project, since it allows me to try languages it didn't use or used months/years ago.:github: https://github.com/Wervice/birch/
You are welcome to leave a ⭐.

PostgreSQL. Устройство карты свободного пространства
СУБД PostgreSQL способна бысто работать с огромными массивами данных благодаря множеству различных механизмов, таких как карта свободного пространства, позволяющая за короткий промежуток времени найти страницу из основного слоя с необходимым свободным пространством для вставки новых версий строк. В этой статье мы разберемся в устройстве карты свободного пространства, а также познакомимся с алгоритмом получения страницы с необходимым свободным пространством.

SectorC is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written.

For those who know more about compiler stuff: Do you prefer Clang/LLVM over GCC or vice versa? Why?
I know there's no one-true-answer to this but I am interested in hearing opinions. I am currently trying out Clang if it would give me better warnings and errors.

I.. I got the actor animations to work in my C game engine...
LOOK! IM SO HAPYP
So the animations now have a thing that they can be set "interruptable" and "loopable." This means that the animation cycle can handle itself. There is no deeper state machine.
For example the enemy death animation now stops instead of looping. And the enemy plays the attack animation properly in midst of moving.
It still looks a bit rough but I'm quite happy how well it came out, I can now move on to other things in the project!
Here's the code: https://codeberg.org/akselmo/artificial-rage/src/branch/actor-update-loop-refactor (I may merge it to main branch soonish.)

Hoping to get some work done on my Icecast-to-HLS tool over my break. Got libcurl support implemented for input, just need to get libcurl output done for posting files to webservers and I should be in a pretty good spot. #programming #opensource #c_programming
