Up there, still quoted: "Why do you call them servers why not just hard disc arrays."

The BBC doesn't own anything, it's a theiving organisation taking your license fee to do as they wish, even if you don't watch their channels.

I set up my own.

When I said make, obviously I meant you buy the parts from Scan etc.

So what would you name an SSD?

The only meaning of sweet I use is for tasty food.

There is no line drawn. It's like a car, a fast car, and a faster car.

>> In 1982 when I had a ZX Spectrum, people referred to the "MIP" as a fast supercomputer. A million calculations per second! But now I have between my home computers 30 trillion calculations per second, 30,000,000 times faster, although it does use 13 amps and create enough heat to open the window in winter.

No, the central heating system would do no calculations.

And it's technically 7 computers although they can be controlled as one.

A normal hobby doesn't use more electricity than I can afford.

One is more complex, one is faster. RISC and so forth.

Seat space vs. storage space. My 7 seater has 5 seats removed, it's now a van. The MOT ignores the missing bits.

Only naked boys with hot abs are allowed in it.

Between you and me, nothing. Health and softy brigade, fuck knows. Probably need to be able to do first aid for dying passengers.
