~7:15pm MAIN Topic: The History of Computing since 1968. Presenter Scott Granneman is going to break it down into decades. So, why talk about all that old stuff? "To understand "how we got here." is how all historians will point out that you want to know the history. What were the problems that we were trying to solve? We are living with the solutions...and the new problems caused by those solutions, so we should understand what was being attempted.

Back in January, Ed Howland told us about the "History of The Unix Shell". And, we learned the above usefulness of history.

So, Scott will give us the decade by decade description of the important events & inventions in computing. And you can understand what they have influenced it your problems today.

Back then, computers ran on punch cards and reel-to-reel tape. A five megabyte hard drive was the size of today's dishwasher. Mini-computers were the size of a deep freeze. Things changed.

Scott is a long time member and frequent presenter of SLUUG. He is the author of "The Linux Phrase Book" from O'Rieley Press.

BASE Topic: Upgrading 2 releases of Debian on web/email server. Part 2. Presenter: Lee_Lammert et al.
More of "how to plan" an upgrade thru 2 major rels of the Debian OS on our web/mail server as well as your system! What need be considered and planned in OUR particular case? But also, what does the discipline of doing this planning show all of our members "HOW TO PLAN" such an effort on their own systems? IE systems that may be MULTI-USER? ...systems that should have high availability & high uptime? IE you can NOT just "be down" until this "kinda works"!

Last month we outlined some of the work we planned for updating BOCK ( our web and mail server ). This will be about the next phase in our transition from Debian 10 to Debian 11 base line.
