I’m a fan of Martin Fowler, I’ve used his blog post on Tech Debt to explain to managers why you can’t just give a 15-year team-killer of an app to a bunch of newbies and expect smooth sailing. His refactoring book is also pretty great. Not necessarily philosophy, or a gripping cover to cover read, but skimming though it as part of a grad school class got me thinking about how I’d refactor my own code and changed my approach to coding (most notably in favoring a series of linq queries/ streams/ es6 array ops, over ugly loops with a tangle of branching logic inside).
