The Simplicity of Prolog
Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are…

Java Hello World, LLVM Edition
After exploring Java bytecode in previous years (2022, 2023, 2024), this year we’ll take an unexpected detour for a Java advent: instead of generating Java bytecode, we’ll use Java to build and execute LLVM IR, the intermediate language behind compilers like clang. Using Java’s Foreign Function & Memory (FFM) API…

Why I'm writing a Scheme implementation in 2025: Async Rust
I really love Rust. I’ve been using it as my language of choice for about ten years now. I believe that it is a remarkably well designed language, and that includes the parts that are often most criticized, most notably async.

Zig; what I think after months of using it
Ah, Zig . I have a love-hate relationship with this one. A “new” (reading: appeared a couple years ago , already — yes, already ), language with high ambitions. Zig was made to run at low-level, with a simple design to solve many problems C has (macros, allocators, error handling, more powerful types like baked-in…

Great things about Rust that aren't just performance
Nearly every line of code I write for fun is in Rust. It's not because I need great performance, though that's a nice benefit. I write a lot of Rust because it's a joy to write code in. There is so much else to love about Rust beyond going fast without segfaults.

Weird Expressions in Rust
Rust has a very powerful type system, but as a result it has some quirks, some would say cursed expressions. There’s a test file, weird-expr.rs , in the rust repository that tests for some of these and makes sure there consistent between updates. So I wanted to go over each of these and explain how it’s valid rust.

Eurydice: a Rust to C compiler
Perhaps the greatest surprise of the last two years was, for me, the realization that people not only care about compiling C to Rust (for obvious reasons, such as, ahem, memory safety) – they also care about compiling Rust to C! Wait, what?
