    A first approximation for a strategy would be to follow a boustrophedon, and keep 2, 4 and 8 near the top, e.g. something like this: . . . . . 4 2 . 8 16 32 . 512 256 128 64

    Tried 3 games, and the scores were 2700, 1200, 5000. So maybe. But then I wrote a function to play it for me: var manager = new GameManager(4, KeyboardInputManager, HTMLActuator); …

    I would be inclined to agree; that value is _not_ entirely caused by scarcity. (Though I will point out that if a resource is scarce, people might put more value on it and try to a…

    The creation of a new coin has no bearing on the scarcity of another. Scarcity is just one requirement for something to act as a currency; another would be that it can be exchanged…

    No, but I just checked a few of the sites we made and none break from ctrl+ (regarding this: I've never seen a non-tech person, i.e. 99% of traffic for the sites, use shortcuts in …

    When I used to work with my designer friend, he would tell me to do things like that: increase this padding by 5px, lighten the color by a little, slightly decrease the border-radi…

    Are you supposed to get it to go through the space between the "stars"? Is it even possible? Edit: Got my first point (50 - 100 tries?). You need to make it go a full orbit without…

    I can't tell if you're being sarcastic... but if not, this is the first legitimate use of uncyclopedia as a source I've seen.

    It depends on the rules of the game. Maybe the rules of life are competitive: you can only increase your score at someone else's expense. The score is either 0-1 or 1-0. (Maybe you…

    There's only one way to add a finite list of numbers, but several ways to "add" infinite lists. Ramanujan summation is just one way. There are also other ways to define "addition" …

    Achilles runs at 1 unit/s and Tortoise at x Well first, Achilles has to travel 1 unit because Tortoise got a head start. That takes 1s. By then, Tortoise managed to run x units, so…

    If cryptocurrencies take off, banks are simply going to store keys for people instead of physical money. For the layperson, nothing will change. However, with cryptocurrency, the g…
