Threads and Goroutines
So after several years of reading oversimplified and flat out incorrect comments about threads and fibers/goroutines/async/etc and fighting this reaction: I’ve decided to write my own still-over-simplified all in one guide to the difference between a couple popular threads and fiber implementations. In order to…

What we talk about when we talk about system design
Early in my research career, I had a chance to work with some of the best system researchers1 in the world on a number of really interesting system designs. One of the enjoyable aspects of research was the particular process used by researchers (particularly in the SOSP/OSDI community) to come up with novel yet…

Rethinking Infrastructure as Code from Scratch

Small joys of programming in Odin
Update (2023-07-21): I was being a bit overly brief with liberal use of ... to mean “unimportant” in the code examples. Ginger Bill (creator of Odin) noted it might be clearer to have more correct/explicit Odin and Zig code for the examples given people would be less familiar. Those has been updated For the past few…

I have written a JVM in Rust
I have built a toy Java Virtual Machine in Rust, complete with garbage collection, exception handling, and the ability to run real Java bytecode using OpenJDK's rt.jar.

Good code is like a love letter to the next developer who will maintain it
We often romanticize the notion of programming, presenting it as an abstract form of art, a science, or even a form of magic. The truth, however, is much mor...

Accidentally Load Bearing
Sometimes people will talk about Chesterton's Fence, the idea that if you want to change something—removing an apparently useless fence—you should first determine why it was set up that way: The gate or fence did not grow there. It was not set up by somnambulists who built it in their sleep. It is highly…

Bfs 3.0: The Fastest Find Yet
bfs is a tool I wrote to do b readth- f irst s earch through a filesystem. It started out simply enough, but over the years it’s grown to include almost every feature from every other find implementation I could find, plus many of its own innovations. The new 3.0 release series includes the biggest new feature so far…

Local async executors and why they should be the default
Imagine you are new to Rust and you want to learn some async programming. Writing a chat server is a common way to start, scope is small enough to contain in a blog post, yet it is complex enough to learn most of what you'll need to build async servers in Rust. One DuckDuckGo query and we are off to the races…

What makes developers productive?
Many ingredients go into developer productivity. Some are obvious and easy to measure (build times are an easy example to point to). But I think we tend to miss other important factors, perhaps because they are hard to directly measure. For example, no system collects a number that shows how well each developer…

Discord is not documentation
I'm going to be slightly contrarian and say that I like Discord. It's great to be able to get real-time help on a problem. And it is fun to see, again in real-time, what other people are working on and struggling with. In truth, Discord is no harder to sign up to than Slack, Matrix, Gitter, IRC, or whatever. And of…

The pull request hack is fucking magic
I don't have time to keep up with all the daft Open Source projects I release. I wish my skill and my energy was as wide as my ambition. Several years ago, I came across Felix Geisendörfer's Pull Request Hack. The premise is simple - if people are making decent Pull Requests to your project then you should give them…

The theory versus the practice of “static websites”
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…
