You have probably heard some variation over the saying: Those who can, do. Those who can't, teach. Those who can't teach, consult. I am actually going to complement my consulting by teaching the next semester, so I guess that puts me quite clearly in the "can't do quadrant"? :-)
Anyway: The subject I am going to teach is a 2nd year college course in computer science, focusing on XML and web technologies, at NITH in Oslo. The gig will be starting in January.
It might have been only a matter of time before I had to try this, with parents that are both teachers... Even so, it is only a thing I do a small portion of my time because I hope it will be energizing and meaningful. Or maybe it'll just be frustrating and make me feel old? I might post some of my experiences after the semester.
With the holiday season coming up I would also like to take the opportunity to wish you the best and suggest you make sure to really recharge those batteries that might be close to running out as everything must be finished in time for Christmas...
 - One might argue that I have tried a little bit already, as guest lecturing and training short courses is something I have done on the side both while I was a student myself and later.
