Decision Tables
I really like decision tables but they’ve fallen out of common knowledge. Let’s fix that. A decision table is a means of concisely representing branching and conditional computations.

Programming the Linux Framebuffer
Previously , I installed Linux on a small ARM Chromebook and set it up without X.Org, using only the console. After neglecting that machine for quite some time, I came back to it because I wanted to try some pixel-graphics programming and the framebuffer seemed like it might be an easy target.

Oops, I Wrote a C++ Compiler
TL;DR I wrote a .NET library that can compile C/C++ code into a byte code that it can also interpret. It is used in my app iCircuit to simulate Arduinos. You can use it yourself with the nuget package CLanguage.

Never patterns, exhaustive matching, and uninhabited types in Rust
One of the long-standing issues that we’ve been wrestling with in Rust is how to integrate the concept of an “uninhabited type” – that is, a type which has no values at all. Uninhabited types are useful to represent the “result” of some computation you know will never execute – for example, if you have to define an…
