Rust to C compiler – 95.9% test pass rate, odd platforms
I am experimenting a bit with a new article format: instead of an overarching theme, this is more of a collection of smaller bits and pieces, sewn together.

Some programming language ideas
Programming languages seem to have somewhat stagnated to me. A lot of shuffling around ideas that already exist, not a lot of new ones.

I Switched from Flutter and Rust to Rust and Egui
This is just a personal experience, there are no absolute truths. Like in any other blog post, a lot of the things you'll read here could be just a skill issue, or legitimate issues. It's up to you to decide.

Zig's Lovely Syntax
It's a bit of a silly post, because syntax is the least interesting detail about the language, but, still, I can't stop thinking how Zig gets this detail just right for the class of curly-braced languages, and, well, now you'll have to think about that too.

Rating 26 years of Java changes
I first started programming Java at IBM back in 1999 as a Pre-University Employee. If I remember correctly, we had Java 1.1.8 installed at that time, but were moving to Java 1.2 (“Java 2”), which w…

A review of Nim 2: The good and bad with example code
I've been using Nim for about 1-2 years now, and I believe the language is undervalued. It's not perfect, of course, but it's pleasant to write and read. My personal website uses Nim .

Ruby and Its Neighbors: Smalltalk
Smalltalk was the second major influence on Ruby's design. A different kind of influence, since almost nothing of Smalltalk's syntax made into Ruby. But many of the details of how objects work are directly inspired by Smalltalk, including the idea that every piece of data is part of the object system.

The Algebra of Loans in Rust
The heart of Rust borrow-checking is this: when a borrow is taken, and until it expires, access to the borrowed place is restricted. For example you may not read from a place while it is mutably borrowed.

Gleam, Coming from Erlang
I recently took some time to try Gleam, the type-safe language that runs on the Erlang virtual machine. For a couple of weeks, I used it to build a little feed aggregator. These are my notes.

Building the Rust Compiler with GCC
If you know one thing about me, it is that I love working on the Rust compiler. Some people kayak, travel or play guitar - and I stare at assembly, trying to figure out what I broke.

Why formalize mathematics – more than catching errors
I read a good post by one of the authors of the Isabelle theorem prover, that got me thinking. The author, Lawrence Paulson, observed that most math proofs are trivial, but writing them (preferably with a proof assistant) is a worthwhile activity, for reasons similar to safety checklists - “Not every obvious statement…

Why SSA?
If you’ve read anything about compilers in the last two decades or so, you have almost certainly heard of SSA compilers , a popular architecture featured in many optimizing compilers, including ahead-of-time compilers such as LLVM, GCC, Go, CUDA (and various shader compilers), Swift 1 , and MSVC 2 , and just-in-time…

Odin: A programming language made for me
In my book Understanding the Odin Programming Language I wrote that “Odin incorporates some of my favorite C best practices, straight into the language”. But I didn’t really elaborate on the details. Let’s do that here! This brings me to talking a bit about a previous job I had. Back in 2021 I worked at a place called…

The Cost of a Closure in C
