Matrices from a geometric perspective
Graphics is all about geometry. In particular, there are points that have a certain color, and the pattern of colors gives you a certain picture.

Writing GUI applications on the Raspberry Pi without a desktop environment (2019)
In a previous article, I explained how I set up a TFT LCD screen on my Raspberry Pi. Because I had been previously using my Pi as a headless server, I hadn’t installed a desktop environment.

Datomic: Event Sourcing without the hassle
When I got started using the Datomic database, I remember someone describing it to me as 'Event Sourcing without the hassle'. Having built Event Sourcing systems both with and without Datomic, I think this is very well put, although it might not be obvious, especially if you don't have much experience with Datomic.
