The Strict Aliasing Situation Is Pretty Bad
One thing that works well in practice in cases where you really don’t want to process single bytes at a time is to use a union for going from one type to another. Granted, writing one member of a union and reading from a different one also isn’t allowed per the standard, but every compiler I’ve come across allows it…

Why Lisp is now an acceptable scripting language
ASDF , the de facto standard build system for Common Lisp, has been vastly improved between 2009 and 2014. These and other improvements finally bring Common Lisp up to par with "scripting languages" in terms of ease of writing and deploying portable code that can access and "glue" together functionality from the…

Long Names are Long
One smart thing Google does is rigorous code reviews. Every change, before you can land it, gets reviewed in at least two ways. First, someone on the team does a normal review to make sure the code does what it’s supposed to.

Visualising the .NET Garbage Collector
As part of an ongoing attempt to learn more about how a real-life Garbage Collector (GC) works (see part 1) and after being inspired by Julia Evans’ excellent post gzip + poetry = awesome I spent a some time writing a tool to enable a live visualisation of the .NET GC in action.

Procedural Dungeon Generation: Cellular Automata
Last time we looked at generating random dungeons for video games using the Drunkard’s Walk algorithm. The Drunkard’s Walk is fun to play with, and often generates cool levels, but it’s also pretty unreliable. That’s not good enough for my purposes: I want to reliably generate big, open, cave-like maps, with lots of…
