Classilla is bringing back web browser support to your classic Macintosh -- built on WaMCom, a port of Mozilla to classic Macintosh systems, using the same technology underpinning the popular Firefox browser. It's completely free and it's open source, and it's standards-compliant. Use it without cost or restriction; or, if you've got the skills, hack it and make it your own. Classilla brings your wonderful old Power Macintoshes back to life and back online.

It takes years maybe decades to master the commands available to you at the Linux shell prompt. Here are 10 that you will have never heard of or used. They are in no particular order. My favorite is mkfifo.
