This tutorial shows how you can enable Compiz Fusion on an Ubuntu 9.04 (Jaunty Jackalope) desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce FX 5200 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.

This tutorial shows how you can set up an Ubuntu 9.04 (Jaunty Jackalope) desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops.

This tutorial shows how to set up an Ubuntu Jaunty Jackalope (Ubuntu 9.04) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box).
