Activating the comma instead of the dot in OOo Calc

GNOME seems to have its own way of managing the numeric keypad, which leads to something very frustrating: the dot (or comma) on the keypad is understood as dot, while the decimal separator in Belgium should be the comma. To change that, I have not found a better solution that to add a line like this in /etc/X11/Xmodmap create it if needed:
keycode 91 = KP_Delete comma
This has been tested on Debian Woody and Debian Sarge, both using GDM and a GNOM

Understanding Memory usage in GNOME

This has been originally written by Miguel de Icaza (the famous GNOME hacker and creator of Ximian). This was retrieved from: http://mail.gnome.org/archives/gnome-list/1999-September/msg00036.html. People usually look at the memory sizes for the processes and misinterpret the information.

HOWTO Automatically clean thumbnails generated by Nautilus

This article is incomplete and was first written in June 2006
for the BeezNest technical website (http://glasnost.beeznest.org/articles/338).
To automatically clean the thumbnails generated by Nautilus, and who never get cleaned by GNOME itself and can really fast occupy a large part of your disk space, I setup a cronjob like this in /etc/cron.d/clean-gnome-thumbnails on my Debian:
#
# Clean GNOME thumbnails files
#
# Every day, at 22h.
0 22    * * *   root    find /home/*/.thumbnails/ -type f -atime +90 -exec rm {} ;
This cronjob would remove thumbnails older than 90

Setting the default printer under GNOME

This article was first written in June 2004 for the BeezNest technical
website (http://glasnost.beeznest.org/articles/135).
To change the default printer when using GNOME, it is pretty easy, provided that you use CUPS and gnome-cups-manager. Go into the "Applications" menu, then "Desktop Preferences", and "System Tools" and click on "Printing". There, you have a list of all preconfigured printers on the system. Right-click on the one you want by default and click on the "Make Default" menu entry.
