    for your "fire in sequence" idea you'd effectively need 4*refresh rate, far easier to do either of the other solutions ;)

    They also contain lead, which is banned from landfills.

    They contain leaded glass, which should be recycled anyway, into more CRTs.

    Besides, show me a LCD monitor that can display 1600x1200 and I'll show you a new car.

  3. Re:Multiple Guns in CRT's on Cold CRT Guns for Thinner CRTs · · Score: 3, Interesting

    Interesting idea.

    However, the electronics to drive it would not be simple. Currently we have 3 fairly high frequency signals, one for each gun (red, green and blue). For this idea you'd need a set of three signals for each separate gun. Assuming you split into 4 subdisplays, you'd need 12 signals (plus the various sync and other control channels). I don't think a common-or-garden graphics card is going to do that very well. Better to do it within the monitor, I'd guess it'd increase the price by about $100.

    Now, the alignment. Not as hard as you imagine; at least all the parts are within one enclosure. The display could auto-calibrate by aligning signals off the edge of the viewable area.

    Cross-talk between the different steering coils would be a far larger problem. You could either compensate for this automatically (increased electronics complexity, expensive, reliability issues) or put in some mu-metal to absorb the field (expensive, heavy)

    I suggest you do a patent search, see if anyone's had this idea before. Personally, I don't think it's feasable ;)

    Oh, and as for energy saving, I don't think so! Electrons lose very little energy during flight.

  4. Re:Oh goody. on WEP Gets A Bit Stronger · · Score: 2

    FreeS/WAN can now be compiled as a module, and is therefore more likely to be resiliant across kernel versions.

    Unfortunately there is little or no chance of getting any real encryption into the kernel, due to various laws etc.

    Yes, FreeS/WAN is a pain. Quite quite braindamaged/damaging in places. Maybe OpenBSD's IPSEC implementation is better; I'm waiting for a new machine to test it on.

  8. Interestingly I have done something similar on Light Emitting Pictures On Standard Inkjet Printer · · Score: 2

    At the lab where I worked we needed a radioactive test pattern for a PET scanner, so I hit on the idea of filling an old inkjet cartridge with oxygen-15 labelled water.

    The half-life is only a few minutes, but that's long enough for the print to dry and to run the test.

    Don't try this at home though, we had 10cm thick lead to put the printer behind!

    Fibre's really not far off.

    Wavelength division multiplexing can give this rate already, but the erbium amplifiers used to boost the signal do not amplify across the whole usable spectrum, so this datarate would only be possible for sub 50km distances.

  14. Re:What about extension cards ? on Fiber On Your Motherboard...Soon! · · Score: 2

    You only need to do the complex terminating when joining raw cable. Many fibre-optic cables come ready terminated, in one of three ways, SC, ST or FC. Additionally, for 'low' bandwidth there are lossy ways of joining two fibres quickly.

    SC and ST are similar, but one of them (ST) has a bayonet-style fitting to keep it firm, FC type has a plug which holds 2 fibres which clicks into place quite nicely. This is usually the type of port that you'll find in mid-range switches.

    I'd expect a connector similar to FC, but designed to connect with out any patch cabling.

    As for how long it took, well it *was* BT...

  22. Nifty stuff on The Joys Of Losing Your Cooling Device · · Score: 2

    I'm sure a lot of people here have cpu overheat stories. Mine fits with Tom's test quite well, but with a slight twist.

    My somewhat weird setup is a P3 in a slocket in an old slot1 BX board. This means that the system cannot monitor the CPU temp and shut it down safely.

    One day after some h/w modification (I seem to recall it was moving a tv card from slot to slot) I must have accidentally jammed a power cable in the CPU fan.

    After about 10 freezes in a day I wonder if my graphics card is overheating. It is as cool as ever (about 40 deg C), so I just touch the P3 heatsink, and blister my finger. So I spit on a spare finger and *tssst* the spit boils away instantly. I turn the machine off, thinking, "Oh well, I wanted to upgrade anyway".

    I cool the poor fevered cpu down with strips of damp tissue paper and find the trapped cable.

    An hour later I nervously turn the machine back on and hey presto, the old thing jumps into life as if nothing happened.

    I'm currently planning to upgrade to an MP athlon, but I will have to have a checklist for when I muck around with anything ;)
