So you're saying theres no difernce beween a server and a set of discs .
When I print the file is sent to a print server, then I can go to almost any networked printer in the university
to collect my printout.

Well here we have print servers and file servers, we have servers for particular groups too.
One speciality server is mostly using GPUs .

What do you mean by your own, in my job the uni pays for them I dont; have to pay for them.
They pay for the imac & the printers and everything else why would I want to make my own ?

Why ?
I doun;t buy the chairs or the tables or anything else, so why should I buy 'servers'
and what is a server anyway I thought you claimed it just linux rack mounted discs.
Surely if you were going to buy such a thing it'd be linux rack mounted discs rather than servers.

Whatever I waned. SS Dave might be a good name.

There are lines drawn some cars aren;t allowed on public roads like the aston martin DB5 reconsrruction
of the james bond car complete with fake guns rotating numberplate and other things , except the ejector seat.
But at a few milliion dollars I assume you'll have yuor own private road to drive it on.
Then theres the formula one cars that can't be driver on public roads.
But there are other divisions the way cars are devided into groups, sports cars' saloons, SUV, hatchbacks, classic, motorsport, family

Well if run properly it could work out whether or not the heating should come on or not based by a thermostat and the ambinet temperature.

you might have to redefine afford. Each PC in my lab uses about 50W not sure how many of them I'd leave on if I were paying for them.
Just had this discussion with the lab manager for the easter period should we shut them down.

A van is the shorted name which comes from caravan.
A friend of mine has slept in his car, so what is a campervan .

can;t get much camper than that.

which could be handy, I'm guess HGV drivers need to know about weight restrictions and height/width stuff and securing loads.
