Slitter: A slab allocator that trusts, but verifies
Slitter is Backtrace’s deliberately middle-of-the-road thread-caching slab allocator, with explicit allocation class tags (rather than derived from the object’s size class). It’s mostly written in Rust, and we use it in our C backend server. Slitter’s design is about as standard as it gets: we hope to dedicate the…

Good Design is Imperfect Design, Part 1: Honest Names
by Eric Evans Perfectionism is a pitfall. For those who, like me, love elegant design and see its utility, there is a slippery slope waiting when a satisfying design does not emerge in a reasonable time. It takes constant self-discipline to recognize this and accept, let go, ship and move on – or return in...

Simple Systems Have Less Downtime (2020)
The Maersk Triple-E Class container ship is 1,300 feet long, carries over 18,000 containers across 11,000 miles between Europe and Asia, and… Its entire crew can fit inside a passenger van. As a former naval architect and a current marketing consultant to startups, I found that

Knuth on Dijkstra (2014)
An excerpt from my book Coders at Work that I frequently find myself wanting to cite mostly because I get a kick out of someone having standing to call BS on Dijkstra:

SQLite Is Dynamically Typed (2020)
A small, cool fact about SQLite is that its columns are flexibly typed. You can store any value in any column! Try it out: sqlite> create table t1 (v1 int, v2 varchar(10)); sqlite> insert into t1 values ("abc", "this string is longer than 10 characters!"); sqlite> select * from t1; abc|this string is longer than 10…

A Bestiary of Functions for Systems Designers
Whether your game surfaces its numbers to the player or not, odds are it has underlying systems that rely on them, and you use functions to determine how those numbers affect each other. In other words, a mathematical function is usually at the core of the answer to a bunch of frequent game design questions.

How to write slow Rust code
I have recently published a blog post that, as I had expected (actually, hoped for, as that would attract people to contribute to the “study”), generated quite some polemic on the Internet!

Learning that you can use unions in C for grouping things into namespaces
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…

Faster CRDTs: An Adventure in Optimization
Some researchers in France put together a comparison showing lots of ways you could implement realtime collaborative editing (like Google Docs). They implemented lots of algorithms - CRDTs and OT algorithms and stuff. And they benchmarked them all to see how they perform. (Cool!!) Some algorithms worked reasonably…

Sorbet Compiler: An experimental, ahead-of-time compiler for Ruby
For the past year, the [Sorbet](https://sorbet.org/) team has been working on an experimental, ahead-of-time compiler for Ruby, powered by Sorbet and LLVM. Today we're sharing the source code for it. It lives alongside the existing code for Sorbet on GitHub, mostly in the `compiler/` folder:

The journey to controlling external monitors on M1 Macs
When M1 Macs were launched, a new GPU with iOS-like architecture started driving the external monitors. This meant that the old method for controlling monitors using DDC wouldn't work anymore. Apps like Lunar and MonitorControl had to find other ways to change the brightness of the monitors.
