Wow there were a lot of bad suggestions in that thread. I was just waiting for 'C Programming for Dummies' to pop up posted by E. Trollguy.

If you work in an object oriented language, I think one of the most useful books you could read would be Kent Beck's Smalltalk Best Practise Patterns. The reason being that the lessons and tricks Kent discusses in his book can be applied to Ruby, Python, Java, C#, C++, Delphi, and any other language that I insultingly forgot, where you are working with objects and polymorphism.

But it certainly wouldn't be useful for _every_ programmer to read. Those would be much more abstract like the already listed ones (mythical man month, sicp, code complete, gof, pragmatic programmer)
