    I can reguraly beat CM8000 and I'm a tentative ~1500+ rated player.

    Are you sure about this? My ELO is around 2200 and has been so for a few years. For you non-chessplayers, that means that statistically I should score about twice as well against a 1500-player than Kasparov should score against me (although admittedly the system tends to break down when the difference is that large, but you get the picture). When playing against CM6000 on the championship-level (full power, no takebacks, etc) on my K6-II 450 Mhz, I almost always get the snot kicked out of me. I've managed a few draws but that's it.

    I am not saying that you're lying, though. Some people are really good at playing closed positions (Stonewall as white and such) and specialize in beating computers. It just seems unlikely. The CM-engine was even rated #1 at one point (in 1999, I believe) on the SSDF-list (SSDF is the voluntary organization that rates chess programs).

    Chess computers are pretty boring. Every single one uses the standard alpha-beta algorithm, used in most games, with modifications for hashing.

    Correct. If the universe works very differently from what is currently thought, the argument certainly fall. This is of course implicit in just about every argument that anyone has ever given for anything.

    as for your possible escape routes.. a borg mind is the best you could come up with?!?!

    Under the assumption that the model is correct, that is one of the few ways that I can see. That does certainly not mean that I think it is the only out.

    heres a little twist on your example. given that we exist now, is there not a good possibility that someone else exists somewhere? in the future or past? or even the present? with the billions upon billions of stars in our known universe, what are the odds that we are THAT much of a fluke?

    Neat twist... You did read the title, right? The argument obviously allows civilizations to get to our population level. Just as long as they do not have significantly higher population and/or are aware of a significant number of other civilization (which would arguably follow advanced technology). If you have a million spots with equal probability that you exist in any of them, you will end up on one of them. Big deal. The quotation from the website refers to this scenario.

    now couldn't we take that and notice that we are still here =) and that every day we are still here, the probability goes up that this loophole in the doomsday scenario is valid...

    You missed the point completely and got "5: interesting"... It's OK though ;)

    The keyword here is observational bias. If there are 100 slots for the agents to exist in, it is unlikely that an agent would find itself being among the 10 first by pure chance, when there is a another explanation that says that there are only 10 slots in the first place. This is a simple and undebatable fact, and hardly the part of the argument that lends itself to attack.

    //Consider this simple program:
    int sum=0;

  15. Advanced alien civilization unlikely on Search for Terrestrial Intelligence · · Score: 4, Interesting
    With large probability, no civilization exists (nor will ever exist) which is significantly more technically advanced than we are right now. This can actually be proven given some basic assumptions and the (much underestimated) technique of proof through observational bias .

    As a warm-up, consider the following computer program: Create an array of agents ("the world"), with 50% probability it contains 10 elements and with 50% probability it contains 100 elements. If an agent knows nothing about the world except the rules, for all it knows there is a 50/50 chance that there are only 10 agents in the world. On the other hand, if it knows that it lives in slot #33, it can conclude that there are 100 agents alive. Now for the twist. If it knows that it lives in, say, slot #9, there is not still a 50/50 chance. Instead the probability is 90% that there only are 10 agents because of observational bias. It is so improbable that the agent should find itself among the 10 first if there really were 100 slots that this strengthens the probability of just 10 agents (write the program and let the agents evolve their guesses through genetic algorithms or something, if you don't believe me). Furthermore if we improve the experiment and let the array be of random size, than the best guess for a smart agent would be that he lives in the last slot or in any case that it is very unlikely that the array is, say, a factor 10 more than its slot number. How does this map to reality? Well, you and I know which slot in time that we inhabit (actually the time is not as important as our birth-number). Based on the same argument it is very unlikely that our race will survive for much longer. If we imagine that we will able to colonize planets sometime in the future, and thus increase our numbers even more, it makes the odds even worse.

    On to the aliens. For the argument above to be fair, we cannot just make an arbitrary division and count the number of humans. We must count everyone/thing that can somehow reason about this issue. Using the exact same argument, we can note that if there is, somewhere in space-time, a race that spans a large amount of stars (i.e with vast technical superiority compared to ours), it is extremely unlikely that you and I would not be one of them.

    The only escape from the logic of the above arguments is, as I see it, either:
    1. In the future we will become like the Borg, one hivemind and thus the actual number of people does not matter, since that one mind does not affect the statistics.
    2. In the future we will evolve to something very strange, which will be uncapable of posing these questions.

    By the way... A little something to make your heads spin even more ;). The above argument also applies to your age. I'll let you figure out the consequences of that one for yourselves...

  17. Re:Wrong on Oracle 9i Isn't Quite Unbreakable · · Score: 1

    You are wrong in so many ways. First of all, a statement about the properties of a program need not be empirical science. If one really wants to, these properties can be proven, for example by lambda-calculus. Thus programming is like mathematics; and just like maths you can of course make mistakes in your proof (the most common being perhaps mistaken assumptions). However, mathematical theorems are generally regarded to be proven (not just "not YET disproven") when enough people have seen it.
    One of the true achievements of the 20th century was the philosophical understanding that the meaning of a word (in this case "proven") is not definable by anything else than the sum of its usage. To say that we cannot have absolute knowledge on the workings of our programs is to take the first step towards a solipsistic view of the world (we cannot know anything with certainty, thus I assert nothing more than that I exist).
    I am willing to debate any solipsists on slashdot on this subject. I am also quite willing to debate those who have not understood the lessons of Wittgenstein, thus making uneducated statements on epistemology to the effect of "software cannot be theoretically unbreakable".
    I find it strange that while most people have some knowledge on what the new findings in physics since the 17th century are, virtually no one knows in what way philosophy have progressed.

  25. Mindmapping desktop on The Next Computer Interface · · Score: 2, Interesting
    I don't think that 3D is the way to go at all. We humans like 2D and have huge prolems thinking in 3D. Also the monitor is a 2D surface (in case you forgot ;) and the mouse/trackball navigates in 2D, so there are huge obstacles to overcome.

    However, the file-cabinet view of the desktop have lots of nice alternatives. I really want a system that treats my desktop like a giant mind-map. Every project that I work on, and all the little notes that I find myself writing all the time would fit great in a mindmap structure. Also having the entire map in a zoomable format would be a better way to use the background than just putting the standard Manga/Astronomy/Softcore/Whatever-floats-your-boat pic there. Furthermore such a desktop would interface nicely with remembrance agents. Imagine having an interactive system (perhaps integrated in emacs, like the one in MIT) that monitors what you write and suggests related nodes, that you have written before.

    And it doesn't stop there! If you have a little checkbox for 'public' on each node/note, a mindmap maps well to a html-site (like MindMan does), so you could easily transform a set of loose thoughts on a subject to something that the entire world can benefit from. The RA could perhaps also interface with something like Everything and the mindmap desktop could have an easy function for uploading nodes/groups of nodes to the community. The entire hivemind of such a network would have an enormous potential.

    Got interesting incoming mail? Tag it with a few keywords and give it a place in the hierarchy and the RA will pop it up when you need it again. The mindmap structure is immensely powerful. Got a whole slew of files in a programming project? Using the same system as you do for all the rest of your documents, you could easily arrange them so as to get a nice visual overview of their interdependence.

    Can you tell that I've been thinking about implementing a desktop (probably in scheme for that schweet scriptability) that does something like this, for a while? ;)
