Cron best practices
The time-based job scheduler cron(8) has been around since Version 7 Unix, and its crontab(5) syntax is familiar even for people who don’t do much Unix system administration. It’s standardised , reasonably flexible, simple to configure, and works reliably, and so it’s trusted by both system packages and users to…

Why WinQuake exists and how it works
When I took a look at the history of Quake binaries, they all made sense to me. quake.exe was the original release, able to run on DOS and Windows 95. Then came vquake.exe to support the hardware accelerated chip Vérité 1000. Later, glquake.exe generalized hardware acceleration to any vendor providing OpenGL drivers…

Introduction to monads in JavaScript
I know, I know, the world does not need yet another introduction to monads (or yet another article complaining that world does not need yet another introduction to monads). So you’ll be glad to know this isn’t one of those, in the sense that it’s not new. I thought I’d write it because, first, monads are worth knowing…

Path Tracing Quake in Blender
This week twenty-five years ago, Quake broke new ground in game engine realism. It was one of the first commercial games to have fully texture mapped 3D scenes rendered in real-time, with pre-computed lightmaps adding an extra layer of atmosphere.

Lessons learned from profiling an algorithm in Rust
Recently, I've been working on a new approximate nearest neighbor search algorithm called RaBitQ . The author has already provided a C++ implementation that runs quite fast. I tried to rewrite it in Rust (yet another RiiR). But I found that my implementation is much slower than the original one. Here is how I improve…

A Rebuttal for Python 3
Zed Shaw, of Learn Python the Hard Way fame, has now written The Case Against Python 3. I’m not involved with core Python development. The only skin I have in this game is that I like Python 3. It’s a good language. And one of the big factors I’ve seen slowing its adoption is that respected people in the Python commu

What Every C Programmer Should Know About Undefined Behavior #1/3
People occasionally ask why LLVM-compiled code sometimes generates SIGTRAP signals when the optimizer is turned on. After digging in, they find that Clang generated a "ud2" instruction (assuming X86 code) - the same as is generated by __builtin_trap().
