Will It Mythos?

https://swelljoe.com/img/full-bench.png
The author created a benchmark suite to test various AI models' ability to find security bugs, specifically those found by Mythos, and found that some models, like Gemma 4 and Qwen 3.6, performed well.
The user discusses the importance of GIF fallbacks for old browsers and explores image compression techniques, including ZopfliPNG and flexiGIF, but finds that flexiGIF can give worse results due to its greedy approach. The user then implements their own GIF compression tool, ZGIF, which uses a hybrid search with pruning to achieve faster results while still beating the current state-of-the-art.

80386 Early Start Memory Access

https://nand2mario.github.io/posts/2026/80386_early_start/timings.png
When Intel designed the 80386, they gave it a trick for hiding memory latency: Early Start. Instead of waiting for an instruction to reach its memory micro-op, the 386 begins the next instruction's address work — effective address, segment relocation, the bus cycle — in the last cycle of the current instruction. Intel put it at about 9% of overall performance. It is also the source of the ...
