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…

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 To make this accessible for people on slow connections as well as people using screen readers, the slides have been replaced by in-line text (the talk has ~120 slides; at an average of 20 kB per slide, that's 2.4 MB.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…

Modern SAT solvers: fast, neat and underused
In part 1 of this series, we built a Sudoku solver based on translating Sudoku to SAT and then giving the resulting SAT instance to a SAT solver. We also benchmarked our solver and found out that it, unsurprisingly, loses to the state of the art of Sudoku solvers. Since

How to make your C codebase Rusty: rewriting keyboard firmware keymap
Recently, my colleague introduced me to QMK 1, an open-source keyboard firmware. Like many non-trivia C projects, macro is heavily used everywhere, especially in keymap files 2. It didn’t bother me much since I have been programming C for many years. But I kept thinking to myself, “what would it look like if I can…

Go compiler internals: Adding a new statement to Go
Updated (2023-05-08): the Go compiler keeps evolving and it takes time to keep up with changes. While the general gist of this post remains true and it's worth reading to understand how the compiler works on a high level, the details of the modifications are slightly different now.

Garbage Collection
We say Lox is a “high-level” language because it frees programmers from worrying about details irrelevant to the problem they’re solving. The user becomes an executive, giving the machine abstract goals and letting the lowly computer figure out how to get there.
