Just when I thought that I had enough things to play with, I discovered some great tools on the 'net.
The first of this (and what consumed me a good amount of time) is pkfix-helper, an auxiliary script for pkfix that guesses the fonts used by old PostScript documents generated by dvips with fonts that are scalable and that are much better to transform to PDF format than bitmapped fonts. I even got some time to write about pkfix so that people get a better idea of what it is all about (the previous version of the document was quite bad).
Another tool that I've been playing with are mind-mappers. One from KDE (which I can't recall right now) and one implemented in Java, called Freemind. Using those tools is quite fun and you also get a better idea of what you have to do (say, using them as a task planner). Interesting stuff.
I just don't understand why it is listed in Debian's contrib section, while it is Free Software and its dependencies seem to be fulfiled with Free Software only (remember that Java has, now, Free virtual Machines).
