The Composition over Inheritance Principle (2020)
In Python as in other programming languages, this grand principle encourages software architects to escape from Object Orientation and enjoy the simpler practices of Object Based programming instead.

Things I would like to see in a computer algebra system
If I were to design a computer algebra system (CAS) from scratch today, I would try to achieve the following goals. Several ideas have already been implemented in one system or another, but certainly not all at once. Some ideas could be adopted by existing CASes; others would require fundamentally different designs or…

Const all the things?
Last week someone posted a /r/cpp thread titled “Declaring all variables local to a function as const”: Ok, so I’m an old-school C++ programmer using the language now since the early ’90s. I’m a fan of const-correctness for function and member declarations, parameters, and the like. Where, I believe, it actually…

Amish Hackers (2009)
[Translations: Japanese] The Amish have the undeserved reputation of being luddites, of people who refuse to employ new technology. It’s well known the strictest of them don’t use electricity, or automobiles, but rather farm with manual tools and ride in … Continue reading →

Zero point leet seconds (2018)
While calculating certain round-trip times, here is a number I came across that is surprisingly memorable: It takes light 0.1337 seconds to travel the length of the Earth's equator via vacuum or air. Let me repeat that. It takes light "zero point leet" seconds to travel once around the equator.

Code quality only matters in context (2019)
I used to obsess about code quality earlier in my career. My experience indicates that I'm in good company here; a lot of us developers spend so much time growing our programming skills, and that kind of drive comes from intrinsic motivation. We care about what we do, and we want to do it well.

Implementing a safe garbage collector in Rust
In my last post I introduced an Emacs Lisp VM I was writing in Rust. My stated goal at the time was to complete a garbage collector. I think Rust has some really interesting properties that will make building garbage collectors easier and safer. Many of the techniques used in my GC are not original and have been…

Julia Macros for Beginners
Macros are a powerful and interesting feature of the Julia programming language, but they can also be confusing. Users coming from Python, Matlab or R have not come in contact with similar constructs before, and they require a different way of thinking about code.

New Clojure Project Quickstart
Clojure beginners sometimes struggle with setting up a new Clojure deps.edn project compared to setting up a lein project. This is one of the reasons I've built neil . But not only for beginners, I've been using neil myself a ton too, to add common features to existing deps.edn projects. You may think that neil is a…

Rust in 2022
In previous years, the core team have asked the community to write new years blog posts about Rust in the coming year. They haven't this year, but I wanted to write one anyway. However, it turned out to be harder than expected. Perhaps that's due to Rust being in an
