How to know what you’ve installed?
I’m doing a presentation on wireless as a school project (so that it can be included in a book ;)) and came across the following problem: neither OpenOffice 2 nor Gimp can read SVG files so I had to convert them in something which they can display (preferably PNG since it can preserve the transparency…

Do NOT simplify when you are explaining!
Or at least make it very clear when you do so! Simplifications and metaphors are very dangerous because they hide some detail deemed non-important by the person who is using them. But you can’t know in which context your explanation will be read (if you are posting it on the Internet), so be sure to…

Updating Ubuntu to Edgy Eft
Finally I’ve gotten around to updating to Ubuntu Edgy Eft (6.10). My first remarks were: The download is quite heavy (677 MB) so it took several hours on my 256 Mbit connection. If you have a good connection at work for example, you should download the ISO, write it to a CD and add the…
