Conveniently enough, I’m not the only blogger on a “be a better programmer while still having a life” kick. If you’re interested in more tips about becoming a better programmer, check out Itamar Turner-Trauring‘s excellent post about learning more tools and techniques while you’re at work.
While you’re at it you should check out Itamar’s Software Clown newsletter, it’s full of great mistakes you can learn from and maybe even avoid running into yourself :)
