Effective Java

Essential book if you’re doing a lot of Java coding. Make sure your colleagues read it as well :^). Very easy to read, I read its 230 pages in about two hours (but that probably depends on your knowledge and experience with Java).

I’ve re-read it three times by now, and it makes me realise that I’m not
programming in Java as much as I used to, but it also makes me realise that I don’t really mind that (..., gee, some story, well, start at http://philip.greenspun.com/panda/server-programming.html).
