If you’re a developer rocking an Apple Silicon Mac and writing in Zig, congratulations - you’ve chosen the scenic route through the desert of profiling tools. It’s just you, your code, and a tumbleweed named Apple Instruments. But don’t worry - we’ll try to find some oases. Okay, it’s not that bad, but we’re far away…
Why most memoization is downright useless...
A brief description of our task scheduling system
It started with a simple thought: four bytes in a hash table bucket look just like an integer. Luckily, this one idea led to a deep dive into bit-twiddling and a 2x performance boost.
As an respectable unemployed person must do, I tried to make Postgres as slow as possible
This last decade has seen an inundation of new JavaScript runtimes (and engines in equal measure), enabling us to run JavaScript in all manner of contexts...
An explanation of some major issues with asyncio.
In this post I will make the case for the concept of a “runtime resizable struct” in Zig. I will then design an API by exploiting Zig’s powerful comptime functionality.
Native CSS transitions have quietly killed the strongest argument for client-side routing. Yet people keep building terrible apps instead of performant websites.
The great indentation war is over and it seems like we have a clear winner.
Never write your own date parsing library. Never. No exceptions. Never have I ever… So… I’ve written my own date parsing library. Why? Our story begins seven…
The fundamental principles needed to get a functional vehicle in your game.
How I develop software at 800 words per minute with a screen reader
Memory safety is all the rage these days. But what does the term even mean? That turns out to be harder to nail down than you may think. Typically, people use this term to refer to language...
Today I'm discussing a trivially simple technique that I've rarely seen used in production codebases. In programming, we often need to deal with simple values that can be represented by simple, generic types built into our programming language or provided by libraries: types like integer, string, or UUID. In any
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Why Elixir is not just a good platform for modern development, but a great one - addressing common misconceptions
After watching this year’s EmacsConf and seeing Guile Emacs being resurrected I thought to myself - why limit ourselves to Guile? Sure, Guile isn’t just a Scheme implementation, thanks to its compiler-tower-based design. Other languages exist for Guile VM, such as Emacs Lisp, and Guile manual lists the following…
Apparently this horse hasn't been beaten enough.
Anubis could not load its JavaScript. The server may be overloaded. Please reload the page to try again.
Looking at old applications, we always wonder who in their right mind thought of building them so badly. But every repository has its story and every effort has noble origins. I encountered such an ap
When you're just getting started with music, you have so many skills to learn. You have to be able to play your instrument and express yourself through it. You need to know the style you're playing, and its idioms and conventions. You may want to record your music, and need all the skills that come along with it.
The target system was a distributed data processing platform that ran across hundreds of thousands of machines. At such scales, a 0.5% improvement would easily make up my salary going forward, and 2% was a good result for the half.
By default, log based on fixed time intervals rather than number of messages.
Super quick one I want to document here! I got myself on a side quest, again! No biggie, my ZSH shell was taking ages to load. When I say ages, more like...

Rust's borrowchecker comes with real downsides
