Why I still reach for Lisp and Scheme instead of Haskell
Scheme (and Lisp) lets you express complex systems and problem domains in simpler terms than any other language can. For all its brilliance, Haskell resists most of the attempts people make to just hack and write useful code quickly.

Tree-sitter vs. Language Servers
I got asked a good question today: what is the difference between Tree-sitter and a language server ? I don’t understand how either of these tools work in depth, so I’m just going to explain from an observable , pragmatic point of view.

Hilariously fast volume computation with the divergence theorem (2018)
The following presents a fast algorithm for volume computation of a simple, closed, triangulated 3D mesh. This assumption is a consequence of the divergence theorem. Further extensions may generalise to other meshes as well, although that is presently out of scope.

Faster asin() was hiding in plain sight
This one is going to be a quick one as there wasn't anything new discovered. In fact, I feel quite dumb. This is really a tale of " Do your research before acting and know what your goal is, " as you'll end up saving yourself a lot of time. Nobody likes throwing away work they've done either, and there could be…

What's the best programming language for coding agents?
This somewhat widely cited post (I keep seeing it cited, anyway) suggests that dynamic languages and/or languages that represent things more concisely are more token efficient. It seems to be cited enough that LLM search results agree. For example, when I searched for "dynamic vs static language token cost" (no…

Watching Go's new garbage collector move through the heap
Go 1.26 made Green Tea the default GC. We observe its cache-friendliness with perf, visualize the heap to see how Go allocates, and poke at a sparse-page problem a non-moving collector like Go's struggles with.

Things Unix can do atomically (2010)
This is a catalog of things UNIX-like/POSIX-compliant operating systems can do atomically, making them useful as building blocks for thread-safe and multi-process-safe programs without mutexes or read/write locks. The list is by no means exhaustive and I expect it to be updated frequently for the foreseeable future.
