    If they don't, people will just ignore them and tunnel. No way to stop that, with the efficient tunnel system already in place and more arriving.

    One very interesting service that I would like to host on my phone is... wait for it... Voice!

    I would like people to call my phone with VoIP. That is a "service", and I need an IP address for it.

    The address space exhaustion is here already. I cannot get any more IP addresses. I only get two, and I pay extra for the second. If I want more I need to switch away from cable modem to something more expensive.

    Luckily I run IPv6 as well, and that gives me 2^80 addresses. It will probably be a while before I exhaust those.

    So do it. But first, you should really switch to IPv6. You cannot do a decent-sized network with a flatter routing with IPv4. So start by joining us -- set up 6to4. Anyone can do it, and all operating systems that matter support it. (Yes, that includes Windows XP.)

  6. Re:"Free" Markets on Electricity Apocalypse Soon? · · Score: 1
    For electricity, if you real want to deregulate, do it right. First, if you want reliability, make the companies financially responsible for outages. If it hits them in the bottom line, they will invest the infrastructure, procedures, etc. to make sure the lights stay on.

    Private companies do not have the kind of funds necessary to pay the losses due to a blackout. If you try to make them, they just go bankrupt. So they will be replaced with a new company that does the same thing, generating profits to its owners until it hits a blackout. And so on.

    The Commission is the only body in the European Union with the power to propose new directives. Therefore it is a legislatory body - and arguably the most powerful legislatory body in the EU.

    AFAIR the 68000 was released after the original IBM PC. That is about the only good reason IBM had for not using the 68000.

    I remember it that way too, but some googling makes me believe that the 68000 was actually out early enough that it could have plausibly been used for the PC. However, the 68000 was always a single-source thing. Intel has been fairly open towards cloning, all things considered.

    Actually, you don't have to use the cable for propulsion.

    Actually you do. It's the whole point of having the cable there at all. You need something to push off of. The only alternative is to throw stuff backwards really fast. The purpose of building a cable is to avoid that method.

  12. Re:harnessing the public interest on Space Elevator Going Up · · Score: 1

    I can do the math myself. Now do the same constant acceleration while staying attached to the cable. For extra points, figure out a way to transfer the energy from the braking of the elevator going down to the elevator going up. Oh and you have to use the cable for propulsion, otherwise you have just invented a strange kind of tethered rocked and you are not saving any energy. Good luck.

    So what? It breaks, we build a new one. So far the most credible threat from a break is that there would be microscopic carbon particles left over from when it burns up in the atmosphere. Those might be harmful. Guess what? Diesel exhaust contains lots already.

    The ascent is going to be very very slow. Imagine going at 100km/h, a speed that would impress most normal elevator designers. 15 days for the ascent, 15 more for the descent. (Admittedly the descent could be done quicker).

    Mutually Assured Destruction has served well in preventing all countries from using nuclear weapons. The only time nuclear weapons were used were when there was no risk of retaliation. The only other scenario where it makes sense to use nuclear weapons is if all is lost anyway and destruction is certain. The shield is only necessary if it is expected that some country will end up with that scenario. As such it is certainly offensive.

    There's one thing I don't get about those energetic neutrons. If you are building a nuclear reactor, you want relatively low energy neutrons, since the high energy neutrons rarely induce a chain reaction. Therefore you use a moderator. But in a fusion boosted fission bomb, what is the moderator?

    I skipped the part about the 8 registers not being true GPRs, just to keep it simple. It just reinforces the point that going to the 64-bit mode is best, since all registers truly are GPR's there. As to the MC 68000, it was very new at the time of the first PC, and only available from a single vendor.

  21. Re:About 64-bit gaming performance on AMD64 Preview · · Score: 4, Informative
    a benchmark of 64-bit gaming performance (say, its 3D calculation or its AI plotting performance) would be mostly a waste of time, as you would see very likely only see an equalling performance at best.

    This would have been the case if IA-32 was a sane architecture. Athlon64 in IA-32 mode has only 8 visible general purpose registers, whereas it has 16 in 64-bit mode. That makes 64-bit mode a win in almost all cases. Technically it would have made sense for AMD to introduce a new 32-bit mode, but it would probably have been bad for marketing.
