Avahi daemon taking up 100% of the processor.

It seems that there is a bug that makes the avahi-daemon overuse the processor - https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/655835. Avahi is a similar thing to Bonjour on the Mac and is for finding other people to chat to, printers to print to etc. http://avahi.org/

To stop it run:

/etc/init.d/avahi-daemon stop

Create or find a new icon 24X24 pixels in png format.

sudo mv win98-start.png /etc/alternatives/start-here-24.png

To see the new icon.

killall gnome-panel

To get a theme fairly close to win98 for Ubuntu use the win2k theme from http://art.gnome.org/themes/metacity

It does warn however that you might not find it easy to change back and I haven't tried going back so be careful if you think you might want to revert.

Bulk Resize Images

From http://www.novell.com/coolsolutions/tip/16524.html

mogrify -resize 320x240 *.jpg

After this command is completed, all of the images will be replaced with resized version of themselves. Notice that in an effort to preserve the image aspect ratio, mogrify may not be produce images that are exactly 320x240. To force this to happen, modify the original command to by placing an exclamation point at the end of the desired resolution:

mogrify -resize 320x240! *.jpg
