Elm is Wrong
A few weeks ago, on a whim my friend and I decided to hackathon our way through an app to help us learn how to play guitar . In a stroke of inspiration, we decided to learn something new, and do the project in the Elm programming language , about which I had heard many good things.

Some mistakes Rust doesn't catch
I still get excited about programming languages. But these days, it’s not so much because of what they let me do, but rather what they don’t let me do. Ultimately, what you can with a programming l...

A comparison of Rust’s borrow checker to the one in C#
OK, so C# doesn’t share the Rust concept of “borrowing,” so it wouldn’t technically be correct to call this “borrow checking,” but in practice when people talk about “Rust’s borrow checker” they’re talking about all of the static analysis Rust does to ensure memory safety, for which I think this qualifies.

Programming With Nothing: FizzBuzz in the lambda calculus in Ruby
I love Ruby! I’ve used it every day for years and I’m not sick of it yet. It’s an easy language to love: it’s expressive, flexible and syntactically beautiful ; it has a unique combination of useful features like mixins , metaclasses and blocks ; it comes with a useful core library and comprehensive standard library …

How Python virtual environments work
After needing to do a deep dive on the venv module (which I will explain later in this blog post as to why), I thought I would explain how virtual environments work to help demystify them. Why do virtual environments exist? Back in my the day, there was no concept

I Wrote a WebAssembly VM in C
For the last 6 months, I’ve been spending my (limited) free time on evenings and weekends writing a WebAssembly VM in C. After repeatedly throwing away small side-projects, this was an extremely productive experience for me as an engineer. I’m writing this in order to put together some take-aways and organize my…

How I turned Zig into my favorite language to write network programs in
I’ve been watching the Zig language for a while now, given that it was created for writing audio software (low-level, no allocations, real time). I never paid too much attention though, it seemed a little weird to me and I didn’t see the real need. Then I saw a post from Andrew Kelley (creator of the language) on…
