sabbatical? what??
so i haven't been here for about 4 months if i'm correct. had 10 pages of "new entries" to go through, only to discover that the "new entries" thing doesn't work the way i think it should. so i probably missed a few posts in there somewhere.
looks like i'm not the only one that's been gone, tho.
just noticed that i had my email address wrong over there on the right. it was missing the 87.
also the "+pln" in it is just so if i ever get spam from it being published on here, i can identify that my address was indeed taken from here. Gmail discards the '+' and anything between it and the '@'. but i'm sure the spammers know that too, and their scrapers probably strip that out before using it. so it's probably pointless is all i'm saying.
i'm jobless over xmas break. don't particularly care for xmas and would be fine with having fir trees and wrapped presents on thanksgiving.
speaking of being jobless, i want to tell you what my "boss" (teacher) and i have planned to do next semester. it's long and technical so feel free to skip it.

Virtualization.
My teacher wants to offer some sort of class where a max of 20 students would each have 4 virtual machines available to them, maybe running XP, 7, Linux, and Server 2003, which would all be networked together ... only within memory, not able to communicate with the school's network. These virtual machines could all be installed on each workstation, but it's certainly less manageable (and less sexy) than running them all on a server set aside for this particular purpose. We figure they probably won't run more than 3 VMs at a time, so that's a theoretical maximum of 60 VMs running on a server. I'm fairly sure that a single server couldn't handle 60 GUI OSes running at once, so we'll probably build 2 or 3 servers. With the crazy advancements in technology plus the crazy reduction in prices, I'm pretty sure I can keep the cost per server under $1000 – and those are pretty beefy 4U rackmount machines.
Accessible from the Internet.
All that above is enough of a challenge, but then he wants to offer the same course in a distance-learning format, which would require those students out on the web to be able to use these VMs for their stuff. So our idea is that they VPN in and then connect to their VMs just like they would if they were actually sitting in the classroom.
Not all 80 at once.
Instead of leaving all 80 VMs running 24/7, we want to only have running the ones that are needed. So my idea is to create a web interface that the students can log into, where they can click a button that would boot up the VM(s) they need, and then give them the IP address of said VM(s) so they could VNC (or RDP) into them. Then they would just shut them down when they're done.
