It hit me that I should really introduce debuggers right from the start. Newbie programmers always debug their code with printf, and that's a habit that takes years to shake.
I'll do some writing about this and check it in. I'm still not back seriously working on this project, but it's always in the back of my mind.
I haven't found time to work on this project, but in the long term, it's still a project I hope to finish.
So this "news" item is just to say: a year of silence doesn't mean I've given up :-)
My current focus is the http://en.swpat.org wiki for campaigns against software patents.
Nothing has changed in my life to give me more spare time, but I've suddenly got an interest in this again.
I've decided to use TexInfo, so learning_gnu_c.texinfo is the file I'm doing development in.
I've fixed a few bugs, including the ones reported by the savannah bug reporting system (thanks Cédric Barboiron). I've also made some very small changes.
I still don't have much spare time, but I'm getting used to working on a lot of projects at once ;-)
Over the next month I'll continue to do occassional work on the book, and in January 2004 I hope to have some regular time for it.
