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. I wanted to add a lightweight heads-up display to the server, and I wanted a graphical application that could operate without X…

Exploring biphasic programming: a new approach in language design
I’ve noticed a small but interesting trend in the programming languages space. I’m not sure how novel it is, but this pattern, which I’ll refer to as “biphasic programming,” is characterized by languages and frameworks that enable identical syntax to express computations executed in two distinct phases or environments…

Code reviews do find bugs
There’s some 2015 research out of Microsoft titled Code Reviews Do Not Find Bugs 1 1 Code Reviews Do Not Find Bugs; How the Current Code Review Best Practice Slows Us Down ; Czerwonka, Greiler, Tilford; IEEE International Conference on Software Engineering; 2015. which seems strangely named because reviewers do find…

Integrated assembler improvements in LLVM 19
Within the LLVM project, MC is a library responsible for handling assembly, disassembly, and object file formats. Intro to the LLVM MC Project, which was written back in 2010, remains a good source to understand the high-level structures. In the latest release cycle, substantial effort has been dedicated to refining…

Convolutions, Fast Fourier Transform and polynomials (2022)
You may remember from high school what a polynomial is. If so, you may also remember how to multiply two of them. But what if I told you that the method you were taught is slow as F? In this post we will connect polynomials with the Fourier Transform and convolutions, and show you how to multiply polynomials with…

Unification in Elixir
Pattern matching is a pervasive and powerful tool in Elixir. This isn't too surprising if you know a little about the history of Elixir's parent language, Erlang. Erlang was originally inspired by and written in Prolog, a logic programming language where pattern matching has first-class support. In

The weirdest QNX bug I've encountered (2021)
I am responsible for the reliability of the firmware updates on our devices and this work never gets boring. The thing about firmware updates is that by definition, every bug is caused by the updater because before installing the affected version, the bug was not present. You could say that updates are the cause and…

A bunch of programming advice I'd give to myself 15 years ago
I finally have the feeling that I’m a decent programmer, so I thought it would be fun to write some advice with the idea of “what would have gotten me to this point faster?” I’m not claiming this is great advice for everyone, just that it would have been good advice for me. If you (or your team) are shooting…
