GitHub Actions Pitfalls
During one of my assignments, I worked with GitHub Actions pretty much every day. I implemented workflows, created new actions, and helped people migrate their projects from jenkins to actions. As much as I like actions – and I like them a lot – there are some things that caught me off guard. I have collected some of…

A bug I wish I hadn't caught
When I catch a bug before release I’m usually glad, because I’ve narrowly averted ruining someone’s experience or eating their data. Today I found a bug that I wish I hadn’t caught, a bug that I wish I’d released into the wild to witness in its full glory. I found this bug in my digital card game Ring of Worlds, and…

Nix wrote half of my debugger
A few days ago I wrote about Rewind VM, a deterministic VM where every run of a Nix build is a pure function of its inputs, thread schedule included! I have been using it to find, reproduce and solve numerous race conditions in Nix builds, but it’s been making me feel a little crazy. What is this superpower, and why…

SSH quoting
A while back there was a thread on one of our company mailing lists about SSH quoting, and I posted a long answer to it. Since then a few people have asked me questions that caused me to reach for it, so I thought it might be helpful if I …

Code-GUI bidirectional editing via LSP
I built a small proof-of-concept for a system that enables real-time bidirectional editing between any modern code editor and a GUI, enabled by an LSP1 server. Code-based CAD I like working on small projects at home that benefit from CAD. I’m also a programmer with a personal development environment that I’ve spent…

Janet for Mortals (2023)
I wrote a book. It’s called Janet for Mortals, and it’s free, and it’s on the internet, and you can read it right now. And you should read it right now, instead of reading this blog post, because this blog post is not very interesting if you haven’t read the book. Heck, this blog post is not very interesting even if…

Redis Geo
Note (version) : I wrote this originally as a Redis module in early 2014, then Redis included a modified version directly into official Redis releases in 2016. Note (implementation) : The implementation included with Redis 3.2+ changed some parameter orderings from my original (intentional, well-thought-out) design…

Anatomy of an ELF executable
Almost every one of you must have written a program, compiled it and then ran it to see the fruits of your hard labour. It feels good to finally see your program working, isn’t it? But to make all of this work, we have someone else to thankful too. And that is your compiler (of course, assuming that you are working in…

On Learning Rust and Go: Migrating Away from Python
I first started using Python in 1993. It's been my main programming language since about 2000. I've written a ton of code in Python, both for work and in my free time. For several years now, I've been growing dissatisfied with it. Partly it's because I'd like more help from my programming tools, such as static type…

Code is not Literature
I have started code reading groups at the last two companies I’ve worked at, Etsy and Twitter, and some folks have asked for my advice about code reading and running code reading groups. Tl;dr: don’t start a code reading group. What you should start instead I’ll get to in a moment but first I need to explain how I…

Files Are Fraught with Peril
This is a psuedo-transcript for a talk given at Deconstruct 2019. To make this accessible for people on slow connections as well as people using screen readers, the slides have been replaced by in-line text (the talk has ~120 slides; at an average of 20 kB per slide, that's 2.4 MB. If you think that's trivial…
