Reminder: WLUG Meeting Next Wed (3/9) Topic: Virtualization Technologies

by Tim Keller

Hey Everybody, This is a reminder that next Wednesday I'm going to be giving a talk about virtualization technologies. I plan to do some white boarding, slides and a demo of different virtualization products currently on the market (both closed and open source). If anybody has specific questions or specific things they'd like to me to cover let me know and I'll update/expand my slides and notes to cover it. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Re: [Wlug] KO

I still have such a fondness for VMS, that I still own a VAXstation 3100 and occasionally pony up for the DECUS license for OpenVMS .... :) On Sun, Feb 13, 2011 at 10:24 PM, John Stoffel <john(a)stoffel.org> wrote: > > Vaxes were clustered years ago.

Re: [Wlug] KO

Vaxes were clustered years ago. You could reboot each member of a cluster without impacting applications running on the cluster if you were careful. And swap out hardware, etc. Very cool stuff. I started on DEC-20 at WPI years ago, and missed the VMS side of things when WPI got the Encore Multimax instead of a VMS cluster. John

Remembering KO

by Ken Jones

I shall reveal my age. I was a working AN/FSQ7 programmer in Group 67 at Lincoln Labs when KO took off on his crazy venture to that mill in Maynard. I did not know Ken at the time as he was in Group 64 if my memory serves me correctly. DEC's first products were 'logic boards'. Those were the days of 'wire wrap' breadboarding. Ken's cards built with itty bitty new fangled transistor things slipped securely into a standard wire wrap board. I do not remember any specific cards, but I know they consisted of multiple individual NAND and NOR gates and probably a couple of FLIP FLOPs. >From that came the PDP-1 which I never saw. My memory focuses on the PDP-8 which was popular - so to speak. To put this in perspective the US had just deployed the SAGE air defense computers all around the country to detect and intercept Russian atomic bomb carrying jet airplanes. The SAGE computers used water cooled vacuum tube technology. I suggest, if you can find a library (remember them?), that is open check out "DEC is Dead, Long LIve DEC" The Lasting Legacy of Digital Equipment Corporation by Edgar Schein. (Is it available on NOOK?). My read of that book was that DEC was fine and healthy so long as it's engineers were producing products the customers did not know they needed, ie DEC was never consumer driven. (This is part of why KO was so beloved.) I was a TCP/IP aware person when I went to work for DEC in 1985. Inside those DEC walls DECnet was not only everything, it was the only thing. Ken Jones

KO

by kevin.paetzold

Since we are reminiscing about DEC and KO.... I started at DEC in 1978 working on the DECSYSTEM20. My first manager was one of the first 100 DEC employees and even though I was initially working as a contractor for DEC (on an air force base) in Rome NY we made a trip to Maynard where he introduced me to the mill and to Ken Olsen. It was a fascinating time as I worked at the place which essentially funded the ARPANET and TCP/IP. I went to work in DEC engineering in Marlboro in 1981. Eventually I ended up at Stratus where among other things I now manage the Linux group (I never worked on VMS although I did do some stuff with the Ultrix group). It still amazes me (and many others) that DEC went away. I often tell my engineers that when I see some computer or software technology that DEC did not have I will let them know (there is some but not much that DEC did not have first and for which very little credit is given).
