  1. Re:Even More Simple on Ask Slashdot: What Would Happen If a Hyperloop Train Failed? · · Score: 1

    Nonetheless, I wouldn't be surprised if a hyperloop from SF to SD cost close to 100 billion, since it hasn't been done before, and a regular railroad running through a tunnel can cost more than $100,000,000 per mile.

    Tunnel costs are proportional to tunnel cross sectional area - the hyperloops are designed to have greatly reduced cross sectional area compared to traditional train tunnels.

    Also tunnel costs are proportional to boring time, Musk is reengineering the TBM (tunnel boring machine) for dramatically faster boring.

    The amended version, after their plant on the apple board stole the iphone idea

    Another person clueless about history,

    IBM did the first smartphone (touch screen phone with applications) in 1992, the 'multitouch' features of the iPhone were from the acquisition of FingerWorks in 2005 - a company that a variety of phone companies had been interested in.

    The LG Prada had been released the year before to wide applause by industrial designers for its capacitive touch screen.

    Samsung and Nokia both had touch screen smart phones, but were worried about cost, so hadn't released them yet, because they didn't think people would pay 'that much' for a phone.

    So the 'iPhone idea' wasn't Apples idea at all and being on Apples board almost certainly didn't impact androids development. Apple simply provided the most refined version of the smartphone idea, one that was being simultaneously pursued by all major phone companies.

    Yes, that would be very interesting. Deep Blue may have been a supercomputer, but it was still a human-scale machine. AlphaGo, on the other hand, runs on Google's immense computational cloud, which makes it a lot less impressive.

  6. "lost by a razor thin margin" on China Censored Google's AlphaGo Match Against World's Best Go Player (theguardian.com) · · Score: 2

    AlphaGo doesn't try and maximize its win margin. It would have won by 15 points or more if the winning margin mattered.

    When all paths lead to victory there is numerical instability in the rollouts so a move that gives a 15 point win margin, might, by chance get say 99.995% chance of winning, but one of the billions of other paths that also lead to a win will, by chance - give a rollout of 99.996% chance of winning. So every move in a won game is essentially random and will tend to reduce the win margin against a skilled opponent (who will always make a move that decreases their loss margin) until the win margin is 1/2.

  7. Pick another random game. Chess, checkers, texas holdem, or some made up game. Give both AlphaGo and Ke Jie one hour to study the rules and then let's see who wins.

    There is software called 'general game playing' software that does this, and they do quite well.

  10. Re:No Human Element? on AI Wins $290,000 in Chinese Poker Competition (bbc.com) · · Score: 1

    I thought Poker was a game of understanding your opponents not only based on past actions with cards but also by looking at facial expressions, body language and determining whether or not they have a good hand. Along with that, a big part is developing subtle gestures to throw your opponents off.

    Reading body language only works with really bad players.
    What modern poker AIs do is play 'game theoretically optimal' (GTO). If both players play GTO, then it is a draw, but if your opponent deviates from GTO then your GTO strategy will beat their strategy. If you are playing 'bad' players you can deviate from GTO and win even more than the GTO win rate (this is called exploitation), but it is better to simply play GTO until you know for sure that your opponent has weaknesses to exploit that you can safely exploit.

    I was commenting about the general nature of such studies. Previous studies which have seperated out 'never drink' and 'former drinker' have shown opposite trends to the current study.

    Also this study doesn't actually seperate out all 'former drinkers' from 'non drinkers', see their methodology.

    ". We reclassified non-drinkers as former drinkers if they had any record of drinking or a history of alcohol abuse in their entire clinical record entered on CPRD before study entry."

    This will not capture a significant percentage of the former drinkers who are non drinkers. So contrary to your assertion, the current study did not truly separate out the two categories.

    So is this another study that doesn't differentiate between 'never drink' and people who drank so much that they had to quit for health reasons and thus 'no longer drink'?

    Studies that differentiate between the two tend to show that the never drink people are the healthiest, it is the drank to near death and quit that skew the numbers - and thus the '1 or 2 glasses' are only healthier relative to heavy drinking not to actual abstinence.

    Yesterday, Washington Post ran a story that the Russians hacked our power grid. What happened was a laptop, not connected to the grid, owned by the power company had malware on it. It wasn't even a valid news event, but they reported the Russians did it. Fake News.

    The way you hack a system that is off the internet (air gapped - as most of the hardware that is directly connected to major infrastructure such as refineries and power generation) is that you leave USB sticks with malware on them where a victim will find them.

    The victim then goes 'hmm I wonder what is on this USB stick' - plugs it into the computer, and the malware you put on the USB stick is transferred to the laptop.

    Then once the laptop is used by a technician on the air gapped hardware, the infrastructure gets infected.

    They 'hacked the power company', which is what the story claimed, they simply were unable to bridge the air gap because someone caught the infection in time.

    Since the malware bore the signature of Russian hackers, it wasn't a 'fake' news story, you were simply not well enough informed to understand what was going on.

    That isn't what is typically done in these studies. Rather than using a valid method (statistical correlates of names with race) they instead use forced choice ratios.

    They tend to also use extremely common 'white' names and extremely uncommon 'black' names (The studies that have used common black names such as Ebony; show that the common black name ends up with better response rates than the less common white names).
