Personality Basins
Personality basins are a mental model that I use to reason about humans within their environment: from modelling why people are they way they are, how they change over time, how mental illnesses and addiction function along with how we should look for their cures, and how the attention economy optimizes itself to…

Hi all! I'm starting a new article series here. This one is going to be about Unix utilities that you should know about. The articles will discuss one Unix program at a time.

Using gRPC for (local) inter-process communication (2021)
Using a full-featured RPC framework for IPC seems like overkill when the processes run on the same machine. However, if your project anyway exposes RPCs for public APIs or would benefit from a schema-based serialisation layer it makes sense to use only one tool that combines these—also for IPC. Microservices for…

Lush: My favorite small programming language
I meant to write about this when I started my blog in 2009. Eventually Lush kind of faded out of my consciousness, as it was a lot easier to get work doing stuff in R or Matlab or whatever. The guy…

Using Erlang hot code updates
One of the Erlang ecosystem's spiciest nerd snipes are hot code updates. Because it can do it. In ways that almost no other runtime can. I use Elixir which builds on Erlang and has the same capabilities.

Dear sir, you have built a compiler (2022)
I am afraid to inform you that you have built a compiler. I know you wanted a “simple prototype” that would just add that one feature to your programming model. You said that “SSA is an overkill” and “it’s just way too much infrastructure to maintain for a simple task” and yet, six months later, you have pile of…

Hand Tracking for Mouse Input (2023)
The other day I saw the launch of Apple Vision Pro, the whole thing was very interesting, but one thing that caught my attention was the finger input. It seems very intuitive, by using the finger pinching as sort of like a cursor or mouse input. I figured I want to try it out, so I took it upon myself to create it.

How to Build a Chess Engine and Fail
A Chess-AI is something every programmer should build at least once and [Sebastian Lague’s](https://www.youtube.com/@SebastianLague) [competition](https://www.youtube.com/watch?v=iScy18pVR58) was the perfect opportunity for me to do so. Constrained to 1024 tokens I wanted to implement an evaluation function similar to…

A BBC navigation bar component broke depending on the external monitor
Recently, my team and I fixed an absolutely bizarre bug that only one person in the team could reproduce. And to make it even weirder, she was only able to reproduce the issue when using her work laptop at home; it worked fine with the same laptop in the office.
