Building static binaries with Go on Linux
One of Go's advantages is being able to produce statically-linked binaries [1] . This doesn't mean that Go always produces such binaries by default, however; in some scenarios it requires extra work to make this happen. Specifics here are OS-dependent; here we focus on Unix systems.

Yesterday's Pixels, Today
In August I finished work on a game called Restricted Airspace for the Wonderbundle, a bundle of new games by NYC game designers available as a reward to backers of the Wonderville Kickstarter . It is a 3rd person aerial shooter in the style of the original Star Fox set in a city modeled on Beirut in the 1890s. It was…

The Overengineered Resume with Zola, JSON Resume, Weasyprint, and Nix (2023)
Maintaining a resume is not the most interesting use of time. Naturally, when I needed to bring my own up to date, I decided to spend a great deal more time on it and overengineer the process.

Generating the Alphabet
My current generative artwork-in-progress includes text, but I don’t want to use a font. In browser based art work, using a “web safe” font could produce inconsistent results, while including a font file would mean a large file size. Additionally, I don’t want a visual element of the project to be s

How to test without mocking
Mocking creates false security by testing isolation, not real behavior. Separate business logic from IO, use in-memory DBs, write server-side E2E tests instead.

Python datetime pitfalls, and what libraries are (not) doing about it
It’s no secret that the Python datetime library has its quirks. Not only are there probably more than you think; third-party libraries don’t address most of them! I created a new library to explore what a better datetime library could look like.

How to Structure C Projects: These Best Practices Worked for Me
I recently worked on two different C projects, and I wanted to structure them in a way that would make them easy to maintain and understand. I also wanted to make sure that the projects were easy to build and test. In this post, I will share my experience and the best practices I found for structuring C projects.

Identifying Rust's collect:<Vec<_>>() memory leak footgun
Over the weekend, I was working on a personal Rust project when I ran into an excessive memory usage problem. After an evening of trial and error, I found a workaround to fix the memory usage, but I still didn’t understand how the issue was even possible, so I then spent another evening digging through the source code…

Passing nothing is surprisingly difficult
My day job is in browsers and cryptography , not compilers, yet I often find that I need to spend more of my time working through the semantics of programming languages than using them. This post discusses a thorny cross-language issue between C, C++, and Rust. In short:

Formal methods: Just good engineering practice?
Earlier this week, I did the keynote at TLA+ conf 2024 ( watch the video or check out the slides ). My message in the keynote was something I have believed to be true for a long time: formal methods are an important part of good software engineering practice. If you’re a software engineer, especially one working on…

Getting into robotics as a software engineer
Most of my career has been working on web services and mobile apps but at some point this got old for me—in high school I was part of a soldering club and I had this lingering feeling that I wanted to get into ‘harder’ problems. Two years ago I started looking around for companies in Amsterdam and came across…
