  1. Re:Measly milliamps on IBM Develops Transistor Capable of 210GHz · · Score: 1

    As far as I am aware transistors draw significantly more current whilst switching state. Whether it is "on" or "off" is pretty irrelevant.

  2. Re:Hard Disk Drives are noisy on Building Quieter Computers · · Score: 1

    My 7200rpm drive runs hot to the touch. The metal chassis must act like a heat sink. I wouldn't risk insulating it with cardboard, especially if you are reducing unnecessary cooling elsewhere too.

  3. Re:audio on New Sony Clie: PalmOS Is Back in Style · · Score: 2

    FYI, ATRAC is the codec used by Minidisc.

    Question: Where does it say in any of the articles that the video quality is "high quality" or "full screen"?
    Answer: It doesn't.

    128Mb over 160 minutes is 12K/s, which sufficient for reasonably "watchable" low quality clips (as well as being pretty nifty for such a nice portable piece of kit).

  5. New? I don't think so. on Walking Around In Spherical VR · · Score: 1
    Does anyone else apart from me rememeber when this was on "Tomorrows World" (an interesting UK technology/innovation program) four or five years ago?

    They played Doom in it!

  6. Related 1995 New Scientist article on Dirt Cheap Telescopes With Liquid Mercury · · Score: 1

    I remember reading about this in a New Scientist
    article a while back. I've looked it up:

    The abstract is
    'Severe technical problems killed the liquid mirror telescope early this century. Now mercury mirrors are back - and they're hunting for space junk'

    From New Scientist magazine, vol 147 issue 1986, 15/07/1995, page 38

    An interesting article if you've got a load
    of back issues lying around or a subscription
    so that you can search the online archive.
    (Free reg possible too)

  7. Talk about net congestion... on Next Generation of Gnutella · · Score: 2

    I'll be interested to see how they deal with the problem of congestion. I know that I hit search engines around fifty times a day. If each one of my (and everyone elses) queries were distributed a la Gnutella, then surely a significant proportion of total bandwidth would be used by those queries alone. Presently, each one of my queries creates a tiny amount of traffic. This is an efficient system. I realise the cost involved in hosting something like google, but google seems quite happy to bear it... I can only see gPulp being a success if it offered a quality of result not available with current systems. A system like gPulp should be fine for specialised searching (i.e. for phone numbers or mp3s) but I doubt it would be able to outperform the brute force of google in a more general case.

  8. Re:STOP THE PRESSES! on Ask Metallica About Napster · · Score: 1
    He did receive something like 19 separate moderations on that, which is probably still the record.

    How can you tell how many moderations it received?

  9. Re:PCD Files on Microsoft Develops Security-Path for Outlook · · Score: 1

    I assume that the three letter filename exstension list is suffering from overcrowding. Files ending in PCD are then either Photo CD images or some other kind of application code.

  10. Workaround: Just use Winzip on Microsoft Develops Security-Path for Outlook · · Score: 1
    Other issues aside, this should not seriously restrict the average users ability to distribute files, since you could just encapsulate the file you wish to send in a zip file or the like.

    There is therefore no need to use Microsoft's handy community website services. As an added bonus, using Winzip might actually decrease download time for recipients with low-bandwidth connections!

  11. Same old story. on Co-Evolving Robots At Brandeis · · Score: 1
    What they appear to have done is combine genetic algorithms with behaviour based robotics. Whilst it looks impressive, don't be expecting anything too impressive in the near future

    1) Behaviour based robotics seeks to reproduce the behaviour of simplistic creatures such as ants and bees. The idea is to incrementally improve on behaviours these robots have, pushing them further and further up the evolutionary ladder. It seems however that there is a limit to how far this technique can go. Noone is going to magically add an all purpose "intelligence" behaviour to one of these things.

    2) Genetic algorithms are powerful, but rely heavily on human tweaking to guide the process. Of course evolution is a powerful process, but the inherenet parallelism of the process in the real world, cannot be simulated effectively and on a large scale using computers. No matter how many boxes you stick together...

    I guess what I am trying to say is this. AI is full of amazing little tricks and techniques. They just don't impress me anymore.

    It says on the site that the graphics chip is the intel 810.

  13. Re:Maybe time to upgrade on Looking at UltraSPARC III · · Score: 1

    I've got an IPX too. The Cognitive Science Department at Edinburgh gave a load of them away for free a while ago. Its got a 400 megabyte SCSI drive and 36 megabytes of RAM. Now I can use Linux and NT at the same time. There is a lot be said for these old systems!
