I am not a techie and thus could any expert please say if there are any data centres in GB offering inexpensive, 'Bring Your Own Server' service with possibility to set up the India holy river water cooled PC into a server for hosting websites? Sorry if this mailing list post is a bit different to the what you are used to. Regards, Meeku

If Quiet is what you want, I've had stuff from QuietPC that's made a tremendous difference. Not particularly cheap though.

PDF manipulation, how to print a misconfigured booklet with 'two pages per page'?
by Chris G 13 Jun '11

13 Jun '11

I have a PDF document downloaded where the (landscape) pages are actually delivered as two pages per 'page'. Thus if you print it in the normal way you get two landscape pages across each sheet of paper. Is it possible, relatively easily, to tell Acrobat Reader (or any of the alternatives) to print each 'page' of the downloaded PDF as two pages on the printer? -- Chris Green

I agree... > The watercooling kit should be open > not closed / sealed unit because it should allow me to put the > distilled water. Unless I have miss-understand, this is a bad idea. In the event of a leak you want to be using non-conductive coolant liquid. $friend had water cooling, it sprung a leak 'thankfully' over only one part, one of this graphics cards, which after being drained and dried still worked. -- James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...?

n.b. I am re-posting with subject line corresponding to the original post, is that the way to respond to mailing list digests? There was an item quite interesting.

Mineral-free ultrapure water has a resistivity of 18.2 megaohm . cm. I'd call that "pretty damn non-conductive", personally. Of course, eighteen megaohm water is capable of leaching sodium ions out of glass, so... DC.

On the subject of mineral oils, i am sure most people have already seen this, but it is still cool, especially if you like Bioshock http://imgur.com/a/jYv3X Ricky On Sat, Jun 11, 2011 at 8:11 PM, Matthew Green <matthew.j.green(a)ntlworld.com> wrote: > Yeah, you can go for cooling fluids which are basically distilled water with > additives (Which is what I've gone for).
