The Elixir 1.12 version introduced some significant changes. The main one is the ability to create scripts and import dependencies via Mix.install. The interactive console can be more helpful in the software development, prototyping and debugging processes.
The conflict between subclassing and composition is as old as object-oriented programming. The latest crop of languages like Go or Rust prove that you don’t need subclassing to successfully write code. But what’s a pragmatic approach to subclassing in Python, specifically?
Musings of a Computer Scientist.
I've worked with a number of clients on Elixir projects and I've onboarded myself, I've been onboarded and I've onboarded others. And compared to my experiences with PHP/Python/Javascript and my limited experience with C#/.Net I have experienced quite a difference.
Update for future readers: Are you looking for a way to undo something with Git? The git undo command won’t help with your current issue (it needs to be inst...
Some reflections on trusting trust, and how deep the rabbit hole goes.
This week twenty-five years ago, Quake broke new ground in game engine realism. It was one of the first commercial games to have fully texture mapped 3D scenes rendered in real-time, with pre-computed lightmaps adding an extra layer of atmosphere.
There are a number of things that people theoretically know how to do, but which aren’t possible because of how software gets made. Some of these are almost forgotten, but there are at least …
The new sqlite-utils memory command can import CSV and JSON data directly into an in-memory SQLite database, combine and query it using SQL and output the results as CSV, JSON …
I’ve been thinking about garbage collection in Rust for a long time, ever since I started working on Servo’s JS layer. I’ve designed a GC library, …
Just a normal day reversing linked lists on the whiteboard.
Confusing corners of the unix utilities
I recently spent some time going through the amazing nand2tetris course, and assignment #9 is to implement something with the Jack programming language that runs on the Hack computer. My friend encouraged me to try writing a raytracer, which is an algorithm that generates physically realistic images by simulating…
Asynchronous Rust is powerful but has a reputation for being hard to learn. There have been various ideas on how to fix the trickiest aspects, though with my focus being on Tokio 1.0, I had not been able to dedicate much focus to those topics. However, Niko’s async vision effort has recently started the discussion…
I’ve been reading John Ousterhout’s A Philosophy of Software Design . At one point in the book, he gives this advice about code comments: Unfortunately, many…
I’ve been hearing about io_uring on and off for the last couple of years. Its a relatively new technology in Linux to allow high-performance IO with very few overheads. Whenever its been mentioned, its usually been presented as a new alternative to select, poll and epoll. This led me to believe that it was just the…

If you read Programming books, then your goal is to learn. If you write Programming books then your goal is to teach. When I wrote my book…
How to turn 256 bits of entropy into a beautiful, avatar-friendly circular SVG: the Hashvatar.
Schema migrations are tricky, especially when planned downtime is not an option. Changes need to be carefully designed to stay backwards compatible so that…
In August, I set out to improve the machine learning ecosystem for Ruby and wasn’t sure where it would go. Over the next 5 months, I ended up...
Types of register explained, and which are available to pass arguments of different types. Call by value and call by reference distinguished.
I used to think that I didn’t need comments if I wrote self-documenting code. However, I have realized that I do write comments, and that I find them really useful. To see how many comments I…
Reasons why bugs might feel "impossible"
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Quick introduction to git internals for people who are not scared by words like Directed Acyclic Graph .
Recently I was doing some work decoding the new Galileo High Accuracy Service data. In short, this new service will allow Galileo (“European GPS”) users to achieve decimeter-level accuracy, which is nice. This “HAS” data is transmitted highly redundantly by making good use of Reed-Solomon encoding. To work with this…
