A couple of good reads I’ve encountered in the last month or so that cover things I’ve thought myself, but are written much better than I would have:

• The Beginner’s Creed - something I’ll probably keep in my notebook in perpetuity.
• Small Functions Considered Harmful - related to my DRY Isn’t Free post.
• I’m an Idiot
• The Wrong Abstraction.

If you’re a programmer/software engineer/whatever, read them, they’re well worth your time.
