My Emacs Lisp book is finished
I am very proud to say that after about 10 months of work I finished writing my Emacs Lisp book . If you haven’t heard of it yet, it’s called “Hacking your way around in Emacs” and it is an intermediate-level textbook on Emacs Lisp, showing a lot of useful things on about 100 pages.

Java in the Small
Java has many features that make it well suited for large, long-lasting projects. But I find it surprisingly good for small tasks as well. Recent language features make it even better. The killer features are compile-time typing and great tool support.

Kill Your Dependencies
This post talks about Ruby but it’s true of every language community: Python, JavaScript, Java, etc. The scourge of dependencies spares no one. This is a dependency visualization of every Rails app I’ve ever used. Does any of this sound familiar: Gemfile with 100s of entries. Test gems loading in production. Each…

Debugging memory corruption: who the hell writes “2” into my stack? (2016)
Several weeks ago we received a bug report from a customer that said their game was crashing when using IL2CPP scripting backend. QA verified the bug and assigned it to me for fixing. The project was quite big (although far from the largest ones); it took 40 minutes to build on my machine. The instructions on the bug…

C Is Best (2025)
Since its inception on 2000-05-29, SQLite has been implemented in generic C. C was and continues to be the best language for implementing a software library like SQLite. There are no plans to recode SQLite in any other programming language at this time.

The use of `class` for things that should be simple free functions
For those who only read above the fold: I don’t say that all object-orientation is bad! OOP, especially classical polymorphic OOP, has a well-deserved place in real code. I’m going to talk about a very specific antipattern that I see with some frequency: the use of class for things that should be simple free functions.

Web automation: Don't use Selenium, use Playwright
For web automation/testing, Selenium has been the de facto "standard" since forever. It's simple to get started with and supports almost every programming language. My problem with it has been: It's good enough, but nothing more. It doesn't work that well with modern, Javascript framework heavy sites (Angular, React

LLMs use a surprisingly simple mechanism to retrieve some stored knowledge
Researchers find large language models use a simple mechanism to retrieve stored knowledge when they respond to a user prompt. These mechanisms can be leveraged to see what the model knows about different subjects and possibly to correct false information it has stored.
