  1. Deliberately open on Wireless Hijacker Dealt First UK Punishment · · Score: 4, Interesting

    Personally, I leave my wireless network deliberately open, and the login message (when seen) says "welcome to...". I do this in a public minded spirit, in the hope that if I need a public network in some other place, some other kind soul will leave one open as well.

    Fixed computers actually on my network are individually firewalled off.

    If I ever find evidence of massive bandwidth leeching, I may change my policy, but even then I would prefer to simply cap non-me connections.

    Morally, I don't feel it is wrong to borrow enough bandwidth off an open wifi node to read a few web pages or collect email.

    Massive bandwith leeching, copyright theft or invading someone else's samba shared files via an open network (that they probably intended to be network private) are off limits, of course.

    These days, I would hope that people are aware that these things are open by default - there have been enough articles in the major newspapers about it, and certainly I would prefer that hardware manufacturers shipped them in a default secure configuration, but I don't think this should prevent people leaving them open if they want to.

    If i leave a plate of biscuits (cookies) just inside the open gate to my garden with a sign saying "take one please", is it a crime for someone to take one?

    I have no reason to expect that he will whisk out a boring image of some glass balls that he rendered in (e.g.) maya in 5 minutes... So what's the rest of the processing time for?

  3. Re:GPL question... on Seminar On Details Of The GPL And Related Licenses · · Score: 1

    This issue seems fairly clear to me:

    Imagine three different situations in which you, as a programmer, develop new code.

    1) You write a completely new program without basing it on someone else's code. You are at liberty to release it under the GPL, under some other licence, or both.

    2) You extend an existing GPL program by modifying some functionality or UI. You have clearly created a derivative work - you must release it under the GPL (if you decide to release it at all), and you may not release those portions you have written under a different licence, because even taken separately they are derivative works of the original!

    3) You use some GPL code (e.g. an algorithm or minor UI component) from another GPL program to perform some subsidiary function of a completely new program that you write. You still must release the whole program under the GPL (if you release it at all), since it is derivative of those parts already under the GPL by containing them. However, since the rest of the program can be considered in some way complete with the GPL'ed parts removed, you can choose, if you wish, to release the parts you wrote (with the GPL parts suitably stubbed out or replaced) under a different licence as well as the GPL.

    So there is no conflict between the GPL and the FAQ.

    I have deliberately not mentioned the LGPL.

    IANAL. IANESR.

  4. UnitedLinux "Free for non-commercial uses" on United Linux is Here · · Score: 4, Insightful

    Item 9 in the FAQ states:

    "Will users be able to download free versions of UnitedLinux for non-commercial uses, similar to how Linux is freely available today?

    Yes, UnitedLinux sources will be made available for free download as soon as version 1 is released."

    What on earth does this mean? How are they restricting the commercial use? Will one 'commercial' copy be sufficient for multiple installs, or will UnitedLinux bring in a per-seat or per-station licence free for commercial use?

    I am not reassured.

  5. The ads pay for the programme? on Turner CEO: "PVR Users Are Thieves" · · Score: 1

    Ignoring the fact that I pay a subscription and still get ads (SKY), does Turner's view mean that a video tape of a programme that contains the ad spots can still be legally distributed? Or did I misunderstand? Perhaps I just have to send a letter to the advertiser to remind him pay the content producer.

  6. Re:Angular momentum on Space Elevator Could Cost Less Than You Thought · · Score: 1

    Just guessing, but the angular momentum is presumably bled off the angular momentum of the elevator, in the same way that extending your legs whilst in a spinning office chair works.

    This is presumably a problem unless you then bring equal mass back down the elevator - why has nobody mentioned imports (people, rocks, deep frozen boze condensates, perfect diamonds and mass produced statues of aliens made out of 'genuine 100% space rock') here?

  7. Re:Mandrake better at hardware detection than wind on A Visual Comparison Between XP And Mandrake · · Score: 1

    In defense of SuSE 7.2, the PS/2 emulation is how usb mice are normally used, the mouse works right from the word go during the Yast2 installer, and the only problem I had is that the mouse wheel did not work straight away.

    SuSE cannot provide the real Nvidia drivers because of licencing restrictions, but they are installed automatically and without fuss the first time you run Yast Online Update, which SuSE Yast2 installer recommends you do the first time it detects you have an Nvidia and installs the Open Source version of the drivers, during initial install.

  8. Re:Hidden Bomb? on Tracking A Thief Via The Sircam Virus? · · Score: 1

    I had one of those for FTP access to a webserver I paid for once, with Planet Online. The device was time synchronised with a similar one in the computer, and in any given 10 second (or so) period, they would both have the same numbers.

    Needless to say, the device was small enough that it was always lost when I needed it.

  9. Lightbulb trick on Technology vs. Cheating at the University of Virginia · · Score: 1

    woo! I have done this trick without the glass of water. It's really fantastic - multiple differently colours clouds of light zooming around inside the bulb, and them Boom! time to clean the shards of glass from inside of something you didn't own.

  12. 5 minutes ago, I could have ported linux to this on Self-Timed ARM Provides Low Power Consumption · · Score: 1

    Great! I have an aposite and timely post at last!

    five minutes ago, I clicked the on-line submission button indicating that I would NOT choose (for my 3rd year project at manchester university):

    Porting Linux to Amulet3
    Project: 704 Supervisor: DAE Categories: SH=C

    Amulet3 is the latest asynchronous version of the ARM microprocessor. Last year, a student designed a demonstrator board based around Amulet3 + an on-board Xilinx chip. This project is to port a cut-down version of linux to the board. Several ports of linux to similar systems exist. See DAE for Details.

    Java running 'native' via the translation layer?
    Amiga / PSX / Nintendo etc emulators running 'native'?

    On the other hand, consider insidious viruses like the C compiler trojan, but built in to the chip (ok so that may not be possible - I don't know how flexible Crusoe's 'firmware' language is).

  17. Very Amusing... on Super Shielded PC Cases · · Score: 1

    On the issue of the case, it is almost exactly the opposite of what I need! My perfect case might have some of these qualities:

    1) Ultra-light frame
    2) Maximum internal size versus frame size

    anyone else care to contribute?

  20. Re:I'm loving this book on Review:The Meme Machine · · Score: 1

    I have read the book, and although it starts off well, and speculates wildly but interesting towards the end, it dithers off into Zen buddism, and the strange and contradictory idea that as "conciousness" is a story telling construct of the memes that only reacts to events and attempts to explain them, but does not direct them (the memes do this for us) then we should make an effort to stop being concious (clear the mind), and somehow all would become harmonious and we would love one another. How was Susan able to make the concious decision to act upon this idea? As the idea itself is a meme, (which tried to replicate itself from Susan to me) why should we believe it?

    On the other hand, the first X chapters make an entertaining and simple introduction to the subject of memes, and gave me a lot of things to think about - The theory is horribly plausible, and the idea of the catholic church as an organism, which uses resources to propragate itself, and has built in defense mechanisms is quite compelling.

  22. Answer the question... Speed, and Encoding on What is the Bandwitdh of a Nerve? · · Score: 1

    The question was : What is the bandwidth of a nerve cell, not what is the processing latency of the synapse...

    Berne & Levy's Priciples of Physiology says:

    "The speed of transmission of information depends partly on the conduction velocity of the axon. Conduction velocity in turn depends on the diameter of the axon and whether it is unmyelinated or myelinated. Unmyelinated axons are generally less than 1micrometer in diameter and conduct at speeds less than 2.5 m/sec. About one second would be required for a signal in an unmyelinated axon supplying a sensory recepton in a person's foor and having a conduction velocity of 1m/s to reach the spinal cord. Myelinated axons have diameters of 1 to 20 micrometers and conduct at speeds of 3 o 120 m/s. A spinal motoneuron wiht an axon that conducts at 100m/s would be able to trigger the contraction of a toe muscle in about 10ms."

    They also point out that certain CNS cells lacking Axons known as "Amacrine Cells" signal information by current flow rather than action potential. This is of course closer to the model of electrical circuits in computers.

    They go on to mention that data in axonal cells is encoded in one of 3 ways : (1) "labelled" lines - eg in the retina - where 1 line corresponds to a unit sensory element (may be more than one cell) (2) Spatial (or other) maps - eg the motor and sensory homunculus (and also the retinal map) and (3) patterns of impulses, where the data is encoded in mean discharge frequency, time of firing, temporal pattern, duration of bursts.

    The third of these is not dissimilar to modem style encoding of information, although the information in any one nerve is usually very specific. The first two however demonstrate that slow serial bandwidth may be made up with massively parallel channels - After all if you were able to download video at a speed of 2400 bps per pixel then a truecolor video would run at 100 fps (and the eye has a lot of pixels).

    The absolute refractory period for unmyelinated cells if on the order of 1msec. The maximum frequency of signals (pulses) is thus around 1000 impulses per second (but remember that precise timing can also be used to encode signals)

    Oh - and the delay at chemical synapses is around 0.5ms.

    Bored yet?

    Anyway, that's my tuppence.
