2010-12-02: A tale of two lenses
Here I discuss two lenses. Both are very new. I've owned them less than three months, and they represent recent developments from the respective companies building them. But appart from that they differ in almost all aspects. Even in the very idea behind their existence.

2010-05-05: A phone for elderly hackers?
The young and smart people people have smart phones. But what phone should an old hacker choose. My answer is Nokia N900. The only snag is that this gadget isn't really a phone.

On this site there is material on photography, music, literature and other stuff I enjoy in life. However, most of it is related to my profession as an Internet programmer and software developer within the area of digital libraries. I have been that at the Royal Danish Library, Copenhagen (Denmark) and, before that, Lund university library (Sweden).

The content here does not reflect the views of my employers. They are now all past employers, since I retired 1 May 2023.
