How to implement an algorithm from a scientific paper
This article is a short guide to implementing an algorithm from a scientific paper. I have implemented many complex algorithms from books and scientific publications, and this article sums up what I have learned while searching, reading, coding and debugging.

Preparing Yourself for Modern JavaScript Development

Inside the C Standard Library
After diving into the C language through K&R, and then studying portability (see C Portability Lessons from Weird Machines ), my next challenge was to take a systematic look at the standard library. To do this I worked through P. J. Plauger’s book The Standard C Library (ISBN 978-0131315099) where he examines an…

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.

A surprisingly arcane little Unix shell pipeline example
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.

Understanding every byte in a WASM module
In my last post, we explored how to build WASM modules, both with and without WASI support, using Clang. In a comment on Reddit, it was mentioned that much of the setup I walked through in that post could be avoided by just leveraging Zig’s WASI supprt. This is a great point, and I would recommend doing the same. The…
