Excessive nil pointer checks in Go
Let’s talk about nil pointer checks in Go. You want to prevent panics in production, but that doesn’t start with a deferred recover. It starts with defensive programming. Check your inputs, check your bounds, and check pointers for nil before dereferencing them. I’ve started to see more nil checks in Go code. In the…

Zigzag Decoding with AVX-512
I’ve been working on speeding up AVX-512 vertex decoding in meshoptimizer recently; in the process I stumbled upon two optimizations that I did not end up using but I thought they might be fun to write about! The optimizations that actually made it in require some higher level background / explanations that will have…

TIL: You can make HTTP requests without curl using Bash /dev/TCP
Minimal container images often ship without curl, wget, or any HTTP client at all. Bash can open a TCP socket through /dev/tcp, which is enough to write a tiny HTTP/1.1 request by hand for quick checks.
