Crafters Meetup: Architecture Kata
Last time I wrote about the monthly Cambridge Software Crafters Meetup which I started attending almost a year ago. In that post I briefly mentioned the Architecture Kata session which I found particularly interesting as I’ve never done anything like t…

Naming Functions: When Intent and Implementation Differ
Most of the time these days when I get into a conversation about naming it tends to be about tweaking the language, perhaps because I think there is a much better term available, or the author is a non-native speaker and they’ve transliterated the name…
