We do not have real issues since October 2004 but we group them by month like mini issues. The latest issue may still grow and change.

Until September 2004 LinuxFocus was published every second month. These are the available issues:

Hubert Kaißer died

One of the former translators of the German team died unexpextedly on 2005-11-19. He was active in LinuxFocus for many years and was a very reliable translator. Our sympathy goes to friends and family.

Goodbye Guido

2005-08-20
After many years of very interesting work with LinuxFocus I (Guido Socher) will leave the project. It is difficult step because LinuxFocus was once my passion and hobby, so there are a lot of feelings involved, but I can't do it forever.

I will move on to http://tuxgraphics.org. The recently started series on microcontroller programming will continue at tuxgraphics.org.

There are a number of people who are willing to continue LinuxFocus. Write to new(at)linuxfocus.org if you want to join them. They need both people and hardware.

During the transition LinuxFocus will stay online. To avoid that the existing site becomes unavailable while possible restructuring is ongoing the new team will settle first at new.linuxfocus.org . LinuxFocus has 12964 files therefore this seems the best solution.

I wish the new team good luck and a problem free start

Regards
Guido Socher
