Ah yes, the classic "vibe coding" manifesto—because nothing screams casual fun like the joy of pointer arithmetic and segfaults! 😆 But please, let's sprinkle some x86 assembly for that extra sprinkle of masochistic flair. 🤖💻

If You’re Going to Vibe Code, Why Not Do It in C?

💻🤖 Matt Godbolt's blog post is basically a glorified diary entry about how he discovered xor's magic in x86 assembly, as if he just found out the sky is blue. 🎉 Shockingly, he didn't stop there and took us on a nostalgic trip back to his 6502 days, because nothing says "I'm interesting" like reminiscing about the golden age of #microprocessors. 🙄

Why xor eax, eax? — Matt Godbolt’s blog

Why do compilers love xor-ing registers so much?

Developer recreates classic shoot 'em up Zaxxon as a UEFI firmware — isometric arcade game coded in x86 assembly for no-OS represents 'total freedom from big tech' #x86assembly

Developer recreates classic shoot 'em up Zaxxon as a UEFI firmware — isometric arcade game coded in x86 assembly for no-OS represents 'total freedom from big tech'

There have been other UEFI games, but this is the first complete arcade game designed to boot directly as firmware.

bim assembly detection

The barely improved editor now adds better heuristics to detect what flavour of assembly language you're using and what architecture you're working on, so it can provide better highlighting appropriate for the platform you're writing code for. It's not perfect, but it now computes a score if it can't tell right away, and decides based on that combination of factors.

It mostly works for x86/64, Z80, and ARM. I probably should get around to adding 6502, 68000, MIPS, and a few others next. 🙂

A very nice writeup about creating mandelbrot in x86 assembly by Claude.

Mandelbrot in x86 assembly by Claude

Inspired by a tweet asking if Claude knew x86 assembly, I decided to run a bit of an experiment. I prompted Claude Sonnet 4: Write me an ascii art mandelbrot …

😴 Oh wow, a 510-byte OS written in x86 assembly—perfect for when you want to relive the glory days of MS-DOS, but with even less functionality! #GitHub must be thrilled to host yet another micro-project that proves size doesn't matter when it comes to lack of practicality. 🚀

I remembered how hard it was to learn some #x86assembly code over 25 years ago without access to the internet.
And I was so happy when I got some bytes into the boot sector of a floppy disk to show a message.

When I did that exercise again,
I was impressed what we could do with 100 bytes of opcodes and some #BIOS calls.

Modern compilers generate 100-KB startup overhead for a simple "Hello-World".
There's a size factor 100 ... but is software 100 times better now?
