    As for thinking the 18th century is part of the medieval period ... that's just tragic.

    If you have clear sky to two of the satellites, you can get a decent idea of where you are

    Almost. You actually need 3 satellites to get a 2D fix, based on the assumption that you're at sea level. Four satellites is enough for a 3D fix. More will give you better accuracy by eliminating the errors/uncertainty in the measurements/data.

    (Remember that with reception from one satellite, all you know is roughly what time that satellite thinks it is - you need the time signals from two satellites so that you can compare them; the difference tells you which one is further away and by how much... so you always need signal from one more satellite than the number of variables you're trying to calculate.)

    None of this activity has anything to do with "capital" in terms of wealth production.

    ... except that the availability of this market is what makes the IPO investment attractive in the first place: I'm much more likely to invest my $100 in shares now, if I know that I can liquidate them whenever I want/need the cash - rather than having to wait for a stock buyback, or hoping for a dividend...

    I may also have an issue with my users installing a dev environment. If they can do that, what's to stop them from bringing in or downloading code that they can compile which then takes advantage of unpatched vulnerabilities?

    If they can bring in or download code in source form, what's to stop them bringing it in or downloading it in binary form? While I agree that there are aspects of the new Fedora policy that are questionable from a security point of view, preventing users from installing a development environment isn't one of them, since it doesn't buy any security at all...

    Government health care by contrast, is forced on everyone. That specific fact is what makes it a death panel. The person does not decide for himself what he is insured against, and is forbidden from doing so.

  14. Re:KVM? on Best Mouse For Programming? · · Score: 1

    Oh, and the schematics - don't have them to hand, but this page has most of the relevant info. (ISTR if you use the cheaper chip the schematic might need to be slightly different - the sense of the write-enable pin is inverted or something, but can't remember the details!)

  15. Re:KVM? on Best Mouse For Programming? · · Score: 1

    The one in the computer in front of me uses a Microchip 24LC21A. I think Microchip will (or at least used to) send you samples of small numbers either free or very cheaply. Or you can use another chip - don't have one to hand, but I think it's a 24LC128 - which is much cheaper. (The difference is that the 24LC21A is specifically designed for EDIDs, but typically you don't actually need the extra functionality so the other chip is just as good...)

  16. Re:KVM? on Best Mouse For Programming? · · Score: 1
    I have successfully used a similar setup, using an Aten 4-port DVI switch rather than a Gefen - though I think the specs are similar. You are correct that it is the EDID not being passed through that causes the computers to think the monitors are getting unplugged, and you are certainly correct that it is annoying (especially with certain brain-dead drivers that, once the monitor is reconnected, refuse to display anything on it until you change the graphics settings!).

    I found that you can make an equivalent to the EDID doctor for not very much money at all - using an EEPROM chip, 4 resistors and a capacitor. You have to splice this into the DVI cable, which is a bit fiddly and doesn't look very pretty, but for me it has worked way better than anything else. (Especially as I have set up another (more complicated) circuit, that detects when my KVM (KM now?) switch switches between computers, and sends the appropriate infrared signals to switch the monitor at the same time :-)

    3. Law should be treated like software: any and all changes should be incorporated into the text, not distributed as amendments.

  21. Re:So I got a new sink..... on Should Network Cables Be Replaced? · · Score: 1

    Finally, most UK toilets are plumbed directly into the mains, so as long as you drink from the cistern rather than the pan, it is a lot safer than the hot tap.
