  1. Re:Old Laptop (aka a "california server") on Energy Efficient and Cheap Servers for Home Use? · · Score: 1

    Why not replace the hard drive in the laptop with a more modern one? I have a tiny Toshiba Libretto that does this job, and despite comming with a 810MB hard disk, it now has a 10GB drive in. The only thing to watch is that most laptop hard drives are not rated for 24/7 operation, so will only last a couple of years before they die. However there is a Hitachi 7200RPM drive at 60GB that comes in a version rated for 24/7 operation.

    Last time I checked Egypt, Libya, Algeria, Tunisia, Morocco where all on the continent of Africa. These countries are largely populated by people of Arab extraction who I would never describe in a million years as black, and are certainly not Nego. However if any of these people emigrate to America they are technically African-Americans who are not black, no matter how the census bureau tries to define the term. Just because the majority of people of African descent in America in black does not make everyone from Africa black.

  3. Re:Damn straight on Movie Playback From 1TB Holographic Disc · · Score: 1

    While SuperAIT is nice, it is really only 500GB native per tape, because Sony claim 1:2.5 compression. I would love to know what they back up to get those sorts of ratios.

    Back in the real world this is 1000GB native per disk so is twice the capacity of first generation SuperAIT. If we used Sony's dodgy compression ratios this is 2.5TB per 12cm disk and a transfer rate of 320MB per second.

    Like a previous poster said, I just want to know when I can buy one.

    Fine by me, let's leave it in Athens on a perminant basis. Heck they even have 14 ski resorts so they could do the Winter Olympics as well. Would solve the problem with IOC members taking back handers in an instant. It would also save a shed load of money with not having to construct new facilities every four years and the resultant impact on the enviroment. The Olympics are Greek after all so hold them in Greece (I am not remotely Greek in anyway in case you are wondering).

  5. Re:$1 billion in energy savings.. on Efficient Power Supply Contest · · Score: 2

    Pretty easy really, you introduce legilislation that requires new power supplies to meet a minimum efficiency requirement of say 75% and tell the companies that you are going to ratchet it up year on year. Old computers get replaced, and old power supplies fail and get replaced. In a fairly short period of time the bulk of power supplies in computers are all high efficiency ones. Sure they will cost a bit more, but when the volumes on high efficiency supplies increase the price will drop over what they cost today.

    We did that in Europe on fridges/freezes over the last 15 years and it has worked just fine. In that case at the start we did not know how to achieve the targets and the manufactures had to do basic research in order to meet the targets. For power supplies we know today how to make them >90% efficient.

    Repeat after me 3V arcs, 3V arcs, 3V arcs.

    This is basic 101 physics, but when two contacts that are at different potentials are brought together, sometime before they make contact there is arcing between the two - period. The lower the voltage the closer the two have to be before they arc, but they will arc. This is why you have to debounce switches in electronic circuits.

  10. Re:wrong on Perfect Digital Skin · · Score: 1

    Er, there has been a fast'ish approximation for about 20 years now, and has been extensively used for the calculation of absorbed doses in radiotherapy treatment planning. The only difference with visible light is that the energies and wavelengths of the photons are different.

    Interestingly radiotherapy treatment planning is now abandoning these fast approximations for individual photon modeling using Monte-Carlo methods as this yields better results, and they now have the computational power to make it feasable.

  11. Re:Old news... on Perfect Digital Skin · · Score: 2, Informative

    It is even older than this. The basic algorithms for sub-skin scattering of photons where worked out about 20 years ago for radiotheraphy treatment planning. All you need to do for visible light is adjust some of the parameters.

  12. Re:Question on The Gimp from the Eyes of a Photoshop User · · Score: 1

    Nope, the MDI is a work around for the fact that in early versions of Windows there was a techincal limitation that stopped one executable having more than one top level window. I think the limitation was lifted in Windows 3.0, but I could be wrong.

    Multiple toplevel windows is of course the only way to go though it took some ten years before Microsoft started using this themselves.

    If you read the article, the problem the reviewer appears to have are that MacGIMP does not have the standard dumbed down, only one toolbar and that the menus are in different places. Well blow me down but the second of those complaints is basically saying I am used to Photoshop and this new package is not Photoshop so if the item is on a different menu or in a different place it is confusing. That is total bunkum.

    Not really album sales for 2003 where an all time record high in the United Kingdom. Though again single sales slumped yet again. The reason for this is obvious though, they are way to expensive to bother with. Three singles would more than cover the cost of an album. I remember when it was more like seven or eight singles to the price of an album.

    That is not the case. The said foreign nations are free to leave the United Kingdom tomorrow if they want. The problem is they don't want to leave. That is their choice. The fact likely to face the death penalty if they return to their home country, or that they might not be afforded a fair trial is the only reason they get to stay in the United Kingdom.

    No but it outlaws incitment. So while it is not illegal to privately fatasize about it, anouncing to the world that necrophilia is a good thing etc. etc. is illegal.

    Frankly this debate is somewhat late coming to slashdot. The problem is that we have here in the UK a case where a man viewed necrophilia pornography on the internet and with in hours killed a young woman to practice such acts for himself. The case is finished and he has been found guilty and handed down a life sentance.

    Most reasonable people would see at least an element of incitment in this. The British Police in light of the past facts are making a responsible call for a crackdown on sites that under existing legislation would be illegal in most countries in the world.

    Where the hell do they get figures of 10 and 30 Tesla from? A 25T magnetic field is about as strong as man can produce without using explosive flux confinement or discharging massive capacitor banks.

    This is high school physics, the magnetic field from a straight conductor is easy to calculate. To get a magentic field of 30T, 1m from a straight contuctor requires a current of 150million amps!!!
