Note: the article was originally circulated on #cleancode and #kohana on Freenode and is now recorded here as an archive. It seems very useful as something to link people to on IRC when they have questions, so feel free to share as well.
At SevenStrokes, we practice Clean Code. Although code speaks louder than words, at the moment my public repositories are heavily outdated. What isn't as outdated, however, is a short introductory guide I wrote on Clean Code for the internal use of SevenStrokes. Although it is a guide which focuses on the basics, it does make some assumptions on the reader having some knowledge about programming. You'll notice that the examples are primarily written in PHP, but are applicable in all languages.
The article answers the question of why good code matters, what is good code, and covers the three pillars of good code: syntax, architecture, and workflow. It shows coding examples of how to write good code, introduces you to the more abstract architectural jargon, and different tools and processes out there.
