Gnucash (Andy Pepperdine)

The financial package is simple to use for keeping track of private accounts.

This session was a learning exercise for all of us when a new installation was shown and ledgers set up for a current account and a credit card, with examples of how to reconcile bank statements against them. There are no notes since we were all feeling our way.

Networks (Mike Godfrey)

Mike Godfrey gave a full demonstration of how to set up a PC running Linux (Ubuntu), and another running Windows XP so that each could see data held on the other via a local switch. The notes (odt) also describe how to let Linux print on a printer that is attached to a Windows machine, and to allow two Linux machines to see data on the other via NFS. The networking area is full of jargon and acronyms, a lot of which are defined in the associated glossary (odt).
