Emacs Reboot #10: Lorem Ipsum

SBPP #2: Smalltalk Patterns in Ruby
Smalltalk Best Practice Patterns continues from the introduction with a brief explanation of patterns. Some notable quotes: About leveraging commonality: “large-scale software re-use has not proven to be the answer”. A lot of the mid-90s OO PR centered around the … Continue reading
SBPP #1: Introduction
The Ruby Rogues are reading Smalltalk Best Practice Patterns for next month’s book club, so I finally got around to ordering a copy. It’s high time, considering that in my experience it’s one of the most consistently recommended programming books … Continue reading
