Is OOXML Artifically Complex?
OOXML is less an act of sabotage than the continuation of a flawed, inelegant lineage.

Default musl allocator considered harmful to performance
In a real world benchmark, the default musl allocator caused a 7x slowdown compared to other allocators. I recommend all Rust projects immediately swap to a different allocator in a musl environment.

SQL needed structure
The data on the page is presented in a hierarchichal structure. The movie page contains a director, a list of genres, a list of actors, and each actor in the list contains a list of characters they played in the movie. You can't sensibly fit all of this into a single flat structure like a relation.

Contracts for C
C++ seems to finally converge with their contracts proposal, I decided to give it a try and come up with ideas how such a thing would look for C. This is in early stages, not a full proposal yet, a…

Fil's Unbelievable Garbage Collector
Fil-C uses a parallel concurrent on-the-fly grey-stack Dijkstra accurate non-moving garbage collector called FUGC (Fil's Unbelievable Garbage Collector). You can find the source code for the collector itself in fugc.c , though be warned, that code cannot possibly work without lots of support logic in the rest of the…

io_uring is faster than mmap
Sourcing data directly from disk IS faster than caching in memory. I brought receipts. Because hardware got wider but not faster, the old methods don't get you there. You need new tools to use what is scaling and avoid what isn't.

Poor man's bitemporal data system in SQLite and Clojure
On trying to mash up SQLite with ideas stolen from Accountants, Clojure, Datomic, XTDB, Rama, and Local-first-ers, to satisfy Henderson's Tenth Law. Viz., to make a sufficiently complicated data system containing an ad-hoc, informally-specified, bug-ridden, slow implementation of half of a bitemporal database…

Speeding up PyTorch inference on Apple devices with AI-generated Metal kernels
Our lab investigated whether frontier models can write optimized GPU kernels for Apple devices to speed up inference. We found that they can: our AI-generated Metal kernels were 1.24x faster across KernelBench v0.1 problems, and 1.87x faster across KernelBench v0 problems.

Indices, not Pointers
There is a pattern I’ve learned while using Zig which I’ve never seen used in any other language. It’s an extremely simple trick which - when applied to a data structure - reduces memory usage, reduces memory allocations, speeds up accesses, makes freeing instantaneous, and generally makes everything much, much…

A staff engineer's journey with Claude Code
This started as an internal Sanity workshop where I demoed how I actually use AI. Spoiler: it's running multiple agents like a small team with daily amnesia.

Quirks of Common Lisp Types
Humans have a tendency toward binary thinking (pardon the pun). If it's not A, it's B. Perhaps because Lisps have REPLs, they are often thought of from the outside as being dynamic, interpreted languages. Our years of Python have taught us that such languages don't really have strong typing - it's all a wild guess…
