Win16 Retro Development
Several months ago I had a go at producing a high resolution 256-color driver for Windows 3.1. The effort was successful but is not yet complete. Along the way I re-learned many things I had forgotten, and learned several new ones. This blog entry is based on notes I made during development.

Girls just wanna have fast MPMC queues with bounded waiting
Disclaimer: An earlier version of this post claimed the structure is wait-free, this is incorrect. Being wait-free requires that failure or suspension of any thread can’t cause failure or suspension of another thread. This queue in fact does not fulfill that requirement. The main section which discusses the wait…

Introduction to Datalog
In contrast to the imperative programming paradigm, declarative programming expresses the logic of a computation without explicitly specifying its control flow. That is, declarative programming focuses on the what , not the how . If you have tentatively researched declarative programming before, you have likely read…

It's probably time to stop recommending Clean Code (2020)
It may not be possible for us to ever reach empirical definitions of "good code" or "clean code", which means that any one person's opinions about another person's opinions about "clean code" are necessarily highly subjective. I cannot review Robert C. Martin's 2008 book Clean Co...

Lua: Good, Bad, and Ugly Parts (2012)
I have been programming in Lua for about 9 months and it seemed like a good time to pause and reflect on my experience with it. I have used various languages over the years -- Perl ( soaplite.com and other projects, including my current consulting work), C ( a DHCP /DNS server for Arduino and a ping-pong juggling…

Why writing a linked list in safe Rust is so damned hard
Before I start this post, let me preface it by saying that I’m not an experienced Rustacean by any means. The excellent foks at /r/rust gave a lot of helpful feedback and cleared up some misconceptions I had. Futher errata and corrections are appreciated. This post is aimed at helping other fledgling rust-learners…

NixOS is making me less afraid
Something funny happened a little while ago: I read about FreshRSS, and it sounded nice, so I installed it on a server and started using it . That would not have happened a year ago, but then again, a year ago I didn’t have any NixOS servers.

The Simplicity of Prolog
Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are…
