In whatever job we do, we always encouter those sneaky problems where we find ourselves using the same tools over and over again. We don't know why we are using them. Or do we ? Is it because they are perfect for their tasks ? Or because they save so much time ? Never mind.
  1. Libero - very fine stuff to solve your programming problems using solid finite state machines.
  2. awk - that wonderfull UNIX tool that let's you parse and manipulate data on a snap.
  3. fly - a cute routine to generate GIFs from a description file, cool for CGI-ing
