Set Debian or Ubuntu server timezone

This one’s an easy one, from the tzselect (1) manpage:

sudo dpkg-reconfigure tzdata

Install a Java Virtual Machine (JVM) plugin for Google Chrome beta running on Ubuntu Linux

Interested in getting Java to work in the just-released Google Chrome on your Ubuntu install? You can always try linking directly to the plugin binary:

$ locate
$ sudo mkdir /opt/google/chrome/plugins
$ cd /opt/google/chrome/plugins/
$ sudo ln -s /usr/lib/jvm/java-6-sun- .

Works for me!
