Uncle Bob's case for building software that survives its own success, bundled with opinions that provoke more argument than the architecture does.

The book that turned software hiring into a sport — written by the ex-Googler who introduced programming challenges to the process in the first place.

Martin Fowler's catalog of named moves for cleaning up code that already works, cited 116 times across Reddit in 7 years as the Clean Code alternative people actually prefer.
#17 The Pragmatic Programmer
