Make: Theory and Practice
make is a widely used and valuable development tool. It's a "build" tool: it builds programs and documentation according to a "recipe". It could really be used for anything where someone edits some files, and then runs a series of processing steps to generate some other form from the edited files. For the most part…

Good coders borrow, great coders steal
Copying and pasting can be dangerous, but then again, so can many aspects of software development when done incautiously. In this post, I’ll take a look at what code copying actually means for software development, what good code theft means, and the pitfalls of copying badly.

A Crash Course on ML Modules (2015)
I was having lunch with a couple of Haskell programmers the other day and the subject of the ML family came up. I’ve been writing a lot of ML lately and mentioned that I thought *ML was well worth learning for the average Haskeller. When pressed why the best answer I could come up with was “Well.. clean language, Oh!…

Shadama: A particle simulation programming environment for everyone
We present a prototype of a programming system called Shadama. Shadama is designed for writing programs that create, control and visualize large numbers of objects. The basic execution model follows the tradition of StarLogo and its "turtles and patches" abstraction. Turtles, Termites, and Traffic Jams: Explorations…

Type inference
Type inference is a major feature of several programming languages, most notably languages from the ML family like Haskell. In this post I want to provide a brief overview of type inference, along with a simple Python implementation for a toy ML-like language.

Lessons learned from a successful Rust rewrite
I have written about my on-going rewrite-it-to-Rust effort at work: 1 , 2 , 3 . And now it's finished, meaning it's 100% Rust and 0% C++ - the public C API has not changed, just the implementation, one function at time until the end. Let's have a look back at what worked, what didn't, and what can be done about it.

Extending Emacs with Fennel (2024)
After watching this year’s EmacsConf and seeing Guile Emacs being resurrected I thought to myself - why limit ourselves to Guile? Sure, Guile isn’t just a Scheme implementation, thanks to its compiler-tower-based design. Other languages exist for Guile VM, such as Emacs Lisp, and Guile manual lists the following…

A lowering strategy for control effects in Rust
The Rust language has incrementally grown a set of patterns to support control-flow effects including error handling, iteration, and asynchronous I/O. In The registers of Rust , boats lays out four aspects of this pattern shared by Rust’s three effects. Today these effects are typically used in isolation, or at most…
