#syscalls — Public Fediverse posts

🔧🤖 Ah, what a noble quest: #coding a web server in #aarch64 #assembly to fill the existential void left by modern conveniences. Because, clearly, the best way to achieve enlightenment is by manually handling #syscalls and discarding decades of progress. 🌐🚀 Enjoy reinventing the wheel, one byte at a time!

NVIDIA just blessed us with a "groundbreaking" open-source #profiler that promises to spy on our GPUs without slowing them down. 🙄 Finally, we can monitor every mundane syscall without feeling like we're swimming through molasses—because who doesn't want more data to ignore in production? 🚀🔍

The irony is that the constraint that you're talking about went away in the early 1980s when processors with more than just a single accumulator register became popular.

Sinclair QDOS is another, roughly contemporary but a few years earlier, example. The 68008 had far more general-purpose registers than the Z80, so the system call TRAPs in QDOS uniformly return an error code in D0 and up to three results in D1, D2, and D3.

🍖 Ah, the "essential" #guide to the #Windows x86-64 syscall table—because everyone just loves a riveting dive into #hexadecimal soup 🥣. Don't worry, by the time you finish deciphering this, Windows 27 will be out and your newfound #knowledge will be as useful as a floppy disk 📀.

🤔 Oh, you wanted to know where the #bytes go? Well, let's take a thrilling tour through the #labyrinth of #syscalls, because nothing screams excitement like relentless file paths and arcane #assembly #language. 🚀 Spoiler alert: it's all gloriously tedious, but don't worry, your bytes are probably somewhere safe... or not. 🤷‍♂️

🎩✨ Behold, the riveting saga of #syscalls on OpenBSD! Because, naturally, manually entering addresses for every build wasn't enough of a party 🚀. Now, watch in awe as one brave soul ports a "real" application to raw syscalls—truly, the Shakespeare of low-level programming! 🐢🔧
