    He might want to take into account that the battery pack in this car is just a little bigger than the starter/lighting/ignition battery in his truck. Like 20 times the size, and could crank his engine for an hour or two continuously if that's what it takes to start it.

    Actually, while you're correct in that it makes most sense to run the engine at optimally efficient RPM until the battery is charged and then cut it off, they were at one stage researching how to make the engine revs follow the car's speed to make it sound more like a conventional car.

    I hope to god they're not stupid enough to do that in the production version. I don't care if it doesn't rev exactly like a normal car, if it doesn't change the way it drives, make it as efficient as possible.

    but their efficiency goes out the window if you let the building cool off significantly and try to heat it back up.

    This makes no sense, thermodynamically. Heat pumps are more efficient (or rather, pump more heat per unit of work input) when the temperature gradient they're pumping against is smaller (as it is when the building's cooler). Buildings also lose heat more slowly as the temperature gradient decreases (as it does when the building cools off). Think of it this way, it takes less energy to boil a kettle once an hour and let it cool off in the mean time, than to keep it at boiling point for that hour.

    The only reason it cost more for you to heat your house intermittently than to maintain a stable temperature was that you were using auxiliary heat to augment your heat pump output, which skewed your overall efficiency down. If you were running a higher-output heat pump then intermittent would once again be more efficient.

    According to Wikipedia, the original prototype used a turbo 3cyl 1L engine, and the production model is slated to use an existing production engine 4cyl 1.4L engine. So yeah, you're right. :)

    The juice has to come from somewhere, and scrubbed coal plants may be cleaner than the exhaust of millions of vehicles, but it is by no means a Free Lunch.

    TANSTAAFL. It's true. That doesn't mean there's no such thing as a cheaper lunch, and one well maintained scrubbed coal plant is definitely cheaper, environmentally, than a million cars.

    Net profit is probably greater for a successful MMO but it's *very* heavily back-loaded. A movie can get away with 1-2 years from a script to announcement to theatrical release. To be actually successful, an MMO will need at least 3-4 years in development plus a lengthy (6+ months) closed alpha/beta AND a similar scale public beta. Call it 5 years all up, for a team of at least 40-50 people. On the other hand, a skeleton crew can continue to maintain that MMO for its 5-10 year lifetime, over which it will generate strong profits if it can maintain a solid userbase.

    If you don't consider economy a meaningful performance metric then you don't know much about racing. In any race with pit stops, your strategy will change depending on how many laps you can get out of a tank. Knowing your opponents' economy is important too - you by knowing the flow rate of the fuel hose and timing their pit stop you know to within a few laps when their next stop has to be.

  16. Re:Wolves on Dogs As Intelligent As Average Two-Year-Old Children · · Score: 1

    According to TFA, wolves score lower than domestic dogs on the intelligence tests used. I suspect this may be an artifact of the test, since wolves are pretty damned smart in their wild behaviors.

    OK, I know this is going to open a whole massive can of worms, and I apologise, but - isn't this similar to the reason non-whites tend to score lower on IQ tests? As in, there's no physiological basis for such a score disparity, but the results indicate one, so it must be cultural. In this case, domesticated dogs have been bred to be good at tasks which humans set them, and so probably 'think more like humans', whereas wolves do not.

    I know that Kelpie or Kelpie Cross are pretty smart. Any dog that's been bred as a working dog is probably at least as smart as a 'special' human. Dogs from breeds that are bred as sheepdogs can be far cleverer than you'd expect.

    Since I've been waiting for an appropriate forum to rant... Skinnerian operant training annoys me. All this pontificating about stimulus and response and 'conditioning' a response... don't be fucking stupid. You ring the bell, then you feed the dog. Then after a while when you ring the bell the dog goes "oh, that's what Master does right around feeding time". There's no special axons grown between the bell-ringing sound detecting neurons and the salivating neurons. Give the dog some damn credit you imbecile.

    You CAN still have LAN parties with Starcraft 2 though, so it's NOT a (entirely) valid point. The only difference is people have to own the game to play it.

    I'm very curious to see whether they'll keep the "install spawn" option that the original game had. You could let one friend install the game from your set of disks, so if someone at the LAN party didn't have it they could still join multiplayer games.

    It's a religious cult disguised cleverly as "treatment" (which they then tell you is lifelong recovery meaning AA meetings for the rest of your life).

    There's a reason that one of the classic games in Transactional Analysis is called 'Alcoholic'.

    From 'Games People Play' by Eric Berne:

    Alcoholics Anonymous, for example, continues playing the actual game but concentrates on inducing the Alcoholic to take the role of Rescuer. Former Alcoholics are preferred because they know how the game goes, and hence are better qualified to play the supporting role than people who have never played before. Cases have been reported of a chapter of A.A. running out of Alcoholics to work on; whereupon the members resumed drinking since there was no other way to continue the game in the absence of people to rescue.
