Is My Teaching Getting Bad?
The results of the final exam of the UNIX - Programming and System Administration I course make me wonder whether I am getting gradually dumb or bad at teaching.
I used to think that as I teach, I am getting to know more and more about the subject, as well as have less errors and more clean formulations in my presentations. My lectures are now available from the video archive, so the students can rewatch me presenting the topics they have not understood the first time again, if they wish. I have switched the presentation format from old and boring black-and-white DVI slides to new, colored, shiny and graphically rich LaTeX-beamer format (thanks to Jiří Boček from servistech). Also the exam format and even some of the questions are still the same as they have been since eight years ago.
So what am I doing wrong?

Outgoing Mail
I archive every e-mail message I have sent since April 1999. Today during making backups of this data I have decided to count how many messages I have sent each year:
| Year | Messages | Bytes | Bytes/message |
|---|---|---|---|
| 1999 | 2110 | 5082832 | 2408 |
| 2000 | 3211 | 9393052 | 2925 |
| 2001 | 4693 | 30317777 | 6460 |
| 2002 | 7122 | 22466804 | 3154 |
| 2003 | 7669 | 25649473 | 3344 |
| 2004 | 5664 | 19496614 | 3442 |
| 2005 | 5311 | 22807724 | 4294 |
| 2006 | 5375 | 22106651 | 4112 |
| 2007 | 4828 | 33458711 | 6930 |
| 2008 | 4575 | 28287830 | 6183 |
| 2009 | 4715 | 27140012 | 5756 |
| 2010 | 4727 | 35894517 | 7593 |
The variance is relatively high, but apparently e-mail messages are getting bigger with time (no surprise here), and I have sent less messages than I used to send five to eight years ago.

I wish happy year 2011 to everyone who reads this blog.
The image is from Pink Granite Coast in Brittany, France. I plan to post a follow-up series about the places I have visited last year, including this one.
