Electrical question - power factors

[Lieutenant Scott]

There will be no heating required in that room.

[Roger Chapman]

Sorry. Put that one down to old age.

[Tim Streater]

Well he did miss out the comma. Without it you are quite justified in assuming he was suffering from hand jitter (see other post).

Not these days. More cycles per watt us the holy grail of processor designers.

Oddly enough I was talking to one of tee designers of the original ARM chips..

"Well we wer Acorn, and we had no money, and we wanted a processor to make microcomputers. Intel had money. Sun had money. Motorala had money, and so did MIPS to while we went RISC with as few transistors on the chip as we could get away with, to keep fab costs down, they put lots on.

So we ended up with a small chip that went bloody fast and was very cheap. They ended up with bigger chips that went bloody fast and got hot.

Only much later, when people started building battery operated computers did we realise we had - through sheer poverty - designed the best chip on the market, in terms of computation power per watt. The rest, is history"

Sub 10W dimwit.

Intel atom. Fanless, Micro ATX board, no graphics at all, and just a couple of 500 GB SATA disks, 512MBram and ethernet.

it SHOULD idle at about 7W peaking at 30W if both disks are spining up and seeking.

64 bit tho. Not QUITE the bunny when scaling web images, but capable of dealing up files faster than a 100Mbps network can server them ...

I've a bit more on the desktop, but not much. Gets too hot in here otherwise,.

Only occasionally need CPU speed or graphics speed - as long as I can do a full screen HD movie or flash movie, and play one 3D game I like a bit, that's enough.

[The Natural Philosopher]

no :

What is it? A ZX Spectrum?

If you can't do grammar, don't complain..

[Lieutenant Scott]

Are you referring to me as a wanker sir?

[Lieutenant Scott]

Look at Gulftown and Bloomfield:

Sandybridge E: Oddly enough I was talking to one of tee designers of the original ARM > chips..

AMD (used to, but I will never trust them) get VERY hot:

protection anyone? Get an Intel.

[Lieutenant Scott]

For sub 10W I thought you must be using SSDs. Does it not access the disks often or something?

Makes no difference to me, in the summer the window is open, in the winter the central heating operates less.

What game?

[Lieutenant Scott]

Why should I bother to make a usenet post grammatically correct? I'm not writing an article for Nature magazine ffs.

And even the way I wrote it, it was obvious which one I meant. I wouldn't have inserted a whole "it" by mistake.

[Tim Watts]

Indeed. In fact there is an arse load of cooling, being a datacenter.

Personally I feel embarassed that 100VMs will be running on 11U's worth of rack. But that's progress...

[Tim Streater]

Oh but you would. It's part of your normal level of incoherence.

[Tim Streater]

Ten out of ten, Captain!

[The Natural Philosopher]

Course not. Most of the RAM is cache as there is f*ck all process running on there and they probably swap out most of the time.

Golly. Its got a gig of RAM. I guess I couldn't get less.

Its cooler in this house with the windows closed in summer

No central heating at the moment bar the aga in the kitchen doing its

700W 24x7..

I like MUDS when nothing better to do. This one runs on Linux. As well as Windoze and OSX

its called 'communication'

If you wat to post rubbish that cant be understood, that's your choice, and its our choice to comment or simply ignore it.

I'm

You're just saying that..

[The Natural Philosopher]

tyerrs ..my Bro in law used to ne a freelance IBMer - now just freelance and making even ore - and his game is re-engineering corporate IT strategies..'out with 50 boxes running Windows NT, in with a blade server, RAID disk and VMware, and then they stick the 50 NT installs back on. Saves a fortune in maintenance, cooling, hardware and power.."

(It might not be NT. whatever corporate windowish crap is current - was current - 7 years ago).

More like your normal lack of comprehension skills. Do you find it difficult to communicate with people with regional dialects?

ample that you had a generator in your garden, and an infinitely thick cabl= e running to a piece of equipment with a bad power factor. =A0Would you be = losing out? =A0Heating in the coils of the generator?

Anything over 75W effectively needs PFC due to rules on harmonic regulation.
