The Need to Grind Concrete Examples Before Jumping Up a Level of Abstraction
If you go directly to the most abstract ideas then you’re basically like a kid who reads a book of famous quotes about life and thinks they understand everything about life by way of those quotes.

Building a WoW (World of Warcraft) Server in Elixir
Thistle Tea is my new World of Warcraft private server project. You can log in, create a character, run around, and cast spells to kill mobs, with everything synchronized between players as expected for an MMO. It was floating around in my head to build this for a while, since I have an incurable nostalgia for early…

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

Building static binaries with Go on Linux
One of Go's advantages is being able to produce statically-linked binaries [1] . This doesn't mean that Go always produces such binaries by default, however; in some scenarios it requires extra work to make this happen. Specifics here are OS-dependent; here we focus on Unix systems.

Yesterday's Pixels, Today
In August I finished work on a game called Restricted Airspace for the Wonderbundle, a bundle of new games by NYC game designers available as a reward to backers of the Wonderville Kickstarter . It is a 3rd person aerial shooter in the style of the original Star Fox set in a city modeled on Beirut in the 1890s. It was…

Autotuner: How to speed up your Rails app
Ruby’s garbage collector is designed to be adaptable, scaling from short Ruby scripts to running apps that serve millions of requests per second. While it’s designed to be adaptable, it may not work optimally for every use case. For this reason, Ruby’s garbage collector supports many parameters that can be used to…

Generating the Alphabet
My current generative artwork-in-progress includes text, but I don’t want to use a font. In browser based art work, using a “web safe” font could produce inconsistent results, while including a font file would mean a large file size. Additionally, I don’t want a visual element of the project to be s
