  1. Why Microsoft is in Vancouver on IBM Seeks US Patents For Offshoring US Jobs · · Score: 1

    Microsoft open a development center in Vancouver because of Visa problems for foreign workers. I know an European (Danish) guy who successfully interviewed for Microsoft, and then couldn't get a visa (in that "lottery" style programme). Microsoft then decided to get him working in Vancouver, and he'll go to Seattle every once in a while to meet up with the rest of the team.

    The PS3 version will be worse than the PC version anyway, and won't include all the maps:

    Epic's Mark Rein has now said maps have had to be cut from the PlayStation 3 version because the next-gen system can't handle them.

    Speaking to IGN, Rein commented that the maps not in the PS3 release didn't sit well on the console "because the system didn't have the resources to produce a smooth gameplay experience."


    The PS3 omgpowerhouse looks less and less powerful...
  9. Forget my reply (parent post) on First 'Quantum Computer Chips' Demonstrated · · Score: 1

    Forget what I said in my , I misread your post. But for RSA and other public key algorithms, the speedup is exponential, so they're effectively defeated by QC. Grover's algorithm is just a quadratic speedup, so it can be defeated by doubling the key size.

    I can also feel obstacles by deflection of air, but at a short distance only... I'm sure many of you can too.

    Have you ever walked in the dark and could feel obstacles near your head? For example, you expect a door to be closed, but suddenly you can feel you're close to it, that has happened me a lot of times... It must be something about the way the air goes around obstacles, which we can probably hear or feel in our skin.

    2- If it had, it would probably be as expensive as the PS3, and would fail terribly (like the PS3 is failing, or probably worse due to having a weaker brand name)

  22. Re:Missed the Boat on August NPD Numbers Look Good For Wii, 360 · · Score: 1

    Sony killed the PS3 with a series of stupid moves. The first of which was to make a console which can't be cheap (at least not in its first years)...

    The PS3 could be a fine choice for the next generation, but apparently it can't work on this one.

  23. Re:Easier to control, maybe on Smarter-than-Human Intelligence & The Singularity Summit · · Score: 1

    Suppose it's a committee, then. The AI now has to convince the entire committee to let it out of the box.

    That's obviously not what I meant. What I meant is the situation in which the AI would need to convince only one person, but any person who it can trick would be fine enough. I was saying that the situation under which only one person interfaces with the AI doesn't seem very likely.

    It doesn't need to be Open Source either - imagine a government developed AI, or one developed in a big company. There's only one copy of the AI running, maybe only one computer which can run it... but several people who could talk to it. Does it seem unlikely to you for some reason?

    After you prove that:

            * Strong AI will actually exist
            * It will be the most powerful thing ever

    Those are two very extraordinary claims you're making -- for that matter, what quantifies "powerful"? Seems to me that, in its little box, the AI has no more power than a Slashdot troll.

    If Strong AI won't exist, then our discussion is pointless, so I'll ignore that possibility.

    I thought it was clear that I meant that it WOULD be the most powerful thing ever if it escaped to the real world. At that point, imagine it could build a body for itself and use all the resources in the world, guided by a brain thousands of times faster than ours, and maybe also qualitatively smarter... improving itself, copying itself, building/seizing more hardware for itself or its drones, inventing new technologies which we don't even dream about... The technological singularity, in other words.

    Seems to me that from the point that:

    a) The AI is out of the box
    b) It can manipulate objects ... it's pretty much the most powerful thing in the world from then on.
  24. Re:Easier to control, maybe on Smarter-than-Human Intelligence & The Singularity Summit · · Score: 1

    Objectively speaking, how do you know that only one person would ever be in control? Assuming we're talking about a developing effort done by many people, is everyone else supposed to trust only one person to interface with the AI? It doesn't make much sense. What situation do you foresee in which only person will ever interact with the AI?

    Subjectively speaking, I think you're thoroughly underestimating the power of intelligence and knowledge...

    Extraordinary claims require extraordinary proof, and the burden of proof is on people who think people (or some specific given person) would be trustworthy enough to control what will be the most powerful thing ever.

    http://en.wikipedia.org/wiki/Electrical_synapse

    Without the need for receptors to recognize chemical messengers, signaling at electrical synapses is more rapid than that which occurs across chemical synapses, the predominant kind of junctions between neurons. The synaptic delay for a chemical synapse is typically about 2 ms, while the synaptic delay for an electrical synapse may be about 0.2 ms.


    2 ms is very hard to get on the internet, isn't it? Maybe when the Internet2 kicks in ;)
