a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

I’ve been writing a load of Swift code recently for work and this has lead me into the world of typed functional programming. The app needs to build certain objects from a comma separated string, and this lead me to applicative functors, which lead me to brain ache but enlightenment. So here’s my thoughts on how I got to understand these a little better.

All of the code is in Swift, so less clean than Haskell. I’m also only a about 6 weeks into Swift development so I probably haven’t got all of the idioms right. I’ve avoided the optional shorthand wherever possible here, preferring Optional<Type> over Type? because I believe the latter is hiding something that helps understand this code in the context of other generic classes.

It’s also long! I think it’s probably the longest blog post I’ve ever written but I found it interesting and useful, for myself, to write. If you’re one of those people who skip to the end of a book to find out whodunit then I’ve included
