Spent most of the day reading up Python's C/API and SWIG. Boy, it's been a long time since I've used C. 4 years or so... I think I grasped a lot of the details though. I guess programming is like biking - you can't unlearn it.

Not that dusting-off all these C books in my shelve wasn't nostalgic enough, but Martin, an old school mate from the Bonn days, sent me my first Unix book that he still had borrowed. It's called "Standard Betriebssystem Unix" by Hans-Josef Heck. It was published in 1991 when Linux was still wearing diapers.

Believe it or not, I learned Unix with that book without actually having a copy of Unix on my computer. At the time I was still using DOS. When I eventually installed Linux, I knew all about cat, grep, chmod and vi. I think I was in tenth grade then. And now just look at these kids today. They feel like computer pros if they can change the color of their Windows XP desktop. Oh well, I'm talking like my grandpa now...
