Dallas has made his slides available.

This month we are going to try something a bit different by bringing back a frequent speaker to refresh our memories on a number of talks that he has presented to us at both chapters. In doing so, he hopes to provide us with even more information on each of his past topics.

At the November meeting of UUASC-OC, our own longtime speaker Dallas Legan will now pick up where he left on passwords, shell programming, creating start-up scripts, and screen scraping. Time permitting, he might even discuss how to create a nitrogen bomb.

Dallas will start by focusing on how to safely e-mail or otherwise transmit a password. Proving this night will contain something for everyone, after he concludes the password encryption portion, Dallas will turn his attention to BASH and teach us job control tricks, process substitution, and aliases.

Dallas is a long-time programmer who has developed code on various systems ranging from PCs to Crays.
