Extending Python with Rust
Sometimes a pure Python script can't just deliver the performance we need. When that's the case we have to resort to writing our logic in a "fast" compiled language like C or Rust and expose the function with through a Python module. This way we get the best of both worlds. Today I focus on how to use Rust for writing…

Bare-Metal Kubernetes, Part I: Talos on Hetzner
I’ve been running a Kubernetes cluster on a mix of virtual and bare metal machines with Hetzner for about a year now, and while the setup has served me well, being a very exploratory exercise at the time it wasn’t very well documented.

Asynchronous Python and Databases
To quote the last part of this blog post, "I think it's [asyncio] really well done, it's fun to use, and I still am interested in having more of a SQLAlchemy story for it, because I'm sure folks will still want this no matter what anyone says.". To that end, SQLAlchemy 1.4 now includes complete support for asyncio …

Useful algorithms that are not optimized by Jax, PyTorch, or TensorFlow
In some previous blog posts we described in details how one can generalize automatic differentiation to give automatically stability enhancements and all sorts of other niceties by incorporating graph transformations into code generation. However, one of the things which we didn’t go into too much is the limitation of…

Why there is no Hitchhiker’s Guide to Mathematics for Programmers
For those who aren’t regular readers: as a followup to this post, there are four posts detailing the basic four methods of proof, with intentions to detail some more advanced proof techniques in the future. You can find them on this blog’s primers page. Do you really want to get better at mathematics? Remember when…

Why static languages suffer from complexity
People in the programming language design community strive to make their languages more expressive, with a strong type system, mainly to increase ergonomics by avoiding code duplication in final software; however, the more expressive their languages become, the more abruptly duplication penetrates the language itself.

Writing HTML in HTML
I've just finished the final rewrite of my website. I'm not lying: this is the last time I'm ever going to do it. This website has gone through countless rewrites – from WordPress to Jekyll to multiple static site generators of my own – but this is the final one. I know so, because I've found the ultimate method for…

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…
