  2. Milestone on Human Go Champion 'Speechless' After 2nd Loss To Machine (phys.org) · · Score: 5, Insightful

    Having a competitive Go engine capable of beating a 9-dan player is huge. Huge.

    Go is a far better demonstration of "intelligence" than chess in the sense that you require some form of actual AI to be competitive in it. The opening book+brute force combo used by modern chess engines is useless here.

    AlphaGo relies heavily on machine learning neural network to play.

    It requires more than skill. Pruning such a massive game tree is no minor feat - in fact, we don't know how to do it even today. All Go engines are based on some form of adaptive AI.

    Again, chess is waaaaay easier in comparison. Pretty much all chess engines work the same way: they start with precomputed moves from an opening book and then move to what's an essentially brute force approach where the engine tries positions, assigns them scores and then picks the highest score available. How these positions are scored / discarded is what separates them, but the base procedure is unchanged. This is also what leads to what chess players call "computer moves" - most chess engines will favor unassuming, conservative moves yielding small positional advantages instead of, well, more "human", intelligent ones. Picking up pivotal moments from classic games (move 17 on Fischer-Byrne, for example) and feeding them to top-rated chess engines is an enlightening exercise.

    This is all but impossible to perform in Go with even modest board sizes. The game complexity, given its simple rules, is just staggering.

    I am still waiting for a computer who can recognize my bags at a conveyor belt at least as efficiently as me

    I've worked with industrial vision devices in the past and trust me, you could set up a machine to recognize luggage as efficiently as a human being today if you wanted to. In fact, it will do better.

    The only thing surprising about the Go event is that it did not happen like ten, or even twenty, years ago. You may be impressed, but I find this most underwhelming.

    That's likely because you don't understand what it involves. Go is unlike chess in the sense that just throwing raw computing power at the problem won't help you at all; for a "small" 13x13 there are over 10^300 valid game trees to compute, and the number gets exponentially worse once the board increases in size. For reference, the estimated number of atoms in the universe is 10^130.

    Google's AlphaGo engine is an actual machine-learning AI which had to be trained plays the game much like a regular person would - Myungwan Kim actually remarked that it feels like playing against a human being. Having a competitive Go engine today is a major milestone, make no mistake about it.

    Agreed, but "decrypting" is the common term used for breaking hashes - you only need one input generating the hash value you're after.

    It is also interesting how most hash algorithms are built around block cipher primitives.

    Gah, never mind :( The article i linked lists a practical attack on SHA-1 (aka SHA160), not SHA-2. Still, it is basically the same algorithm with a larger key so it is a matter of time until someone breaks it too.

    Typically you just brute-force them. SHA256 is a special case because, just like MD5, is effectively broken: you can decrypt them with significantly less operations than the brute force approach would require.

    MS without Intel is not exciting, and Intel isn't particularly well positioned under 10W TDP, except if the user needs to run Windows.

    It featured a fantastic, humorous episode written by Darin Morgan about a monster who is bitten by a man and turns into one. Its a beautiful satire about an alien trying to make sense of human behavior (working 9 to 5, lying about sexual prowess, our love for fast food) and, at one point, he gets hit by a transgender which leads to an hilarious exchange with Duchovny trying to explain transgenderism to Darby.

    So i've just found out that Slate actually run a story on their LGBTQ section titiled Did The X-Files use a transgender character for cheap laughs?. Why, yes. Yes they did. It doesn't matter that the treatment wasn't offensive at all, or that the entire episode was making fun of the human race as a whole, or even that it actually was in line with the transition theme that was the entire point of the episode. Some people got their panties in a bunch because a transgender character threw a punch.

    Cleese is absolutely right here. Then again, he usually always is.
