  1. Re:How is this random? on Fewer Shuffles Suffice · · Score: 1

    Computers don't normally shuffle with the "divide into two stacks and interleave" algorithm. They tend to do more of a "remove a random item from A and place in stack B, repeat until A is empty" algorithm.

    And as for deterministic, you forgot the variable of where the deck is split (size of A relative to B) which is another source of imperfection.

  4. Re:Possible Implementation on Saving Energy Via Webcam-Based Meter Reading? · · Score: 1

    The position of everything should be the same each time. Convert to black & white (not greyscale). Then, because the center positions are known and the position of each number, figure out which "wedge" the point falls into. A wedge is defined as starting with a number and proceeding to the next (like the hour hand in a clock).

    You can compute the coordinates of the wedge ahead of time. I would probably AND/OR the wedge from the picture with a known wedge to quickly compare them.

    0 indicates "filled" (color = black, or 0x0), . indicates "empty" (color = white, or 0x1)

    Check wedge
    0000 .00. ....

    Test wedge A (arrow not in wedge) .... .... ....

    Test wedge B (arrow partially in wedge)

    000.
    00.. ....

    Check wedge & Test wedge A .... .... ....

    (all white)

    Check wedge & Test wedge B
    000. .0.. ....

    (not all white)

    That should give you two possible wedges at most. You can either fudge it (quick) or you can do detailed checking to see which wedge to indicate. Repeat the process for each dial. Record the number. I don't know the graphics libraries for Java, but as long as they are similar in capability to those of .Net (I assume they are), then it should be a couple of hours to implement and work out the major kinks (it isn't that I can't code in Java, but that I haven't had to do any graphics processing in Java).

    There's probably even some DirectX or OpenGL functions that you can use to do the masking even faster.....but again, I don't know them off the top of my head.

    I'm just glad I don't pay per message.....$140+/month just in messages alone....not counting the base plan ($70) and the additional line costs ($10/additional phone = $40) and junk fees, etc. I have to think that if you have teenage kids (at least girls), an unlimited texting plan is a must.

    I assume that number includes both incoming and outgoing. I have asked why she text's so much and it's basically that she can carry on multiple conversations at once and deal with distractions (such as parents) without breaking conversation. So really, she's sending two or three out one minute, and receving two or three the next minute with lulls every once in a while. They basically use text messaging as an IM client without being locked in to a particular service (AOL, MSN, Yahoo, etc.).

    If you send them frequently, you should consider an unlimited plan. I pay $30/month for unlimited messaging with an AT&T family plan. This includes text, mms, and IM (we don't really do much besides text) Here's how my messaging broke down last month:

    My wife - 389
    My 17yo - 1958
    My 15yo - 11039
    My 10yo - 40
    Me - 163

    13,589 text messages for $30. Less than 1/4 of a cent per message. I'm sure some of those were counted twice, but at that price, I don't really care. That isn't even the highest I've seen. The 15yo has had over 20000 by herself in one month.

    I've always considered myself an Achiever. It isn't so much that I want to "win" the game, but I want to see every nook and cranny available to me. That includes how to horribly lose the game. I love RPG games for this very reason, the amount of content available is just so much greater than can be found in an FPS (15 to 20 maps, 20 to 30 different enemies -- including easy vs hard versions, about 80 ways to die). If they ever created a game that generated random side quests that actually fit with the story line and an ever increasing collection of "cool" weapons , I don't think I would need another game......and it's why NetHack never gets old.

    Starting class only determines how you start (starting abilities and inventory)....after a point, all characters evolve into basically the same thing. Even race has only a small bearing on your character after a point (starting intrinsics). There are ways of getting all of the equipment and intrinsics such that by the end of the game, you've collected all of the ones you need.

    Generally, I find Valkyries to be the easiest early on (and most likely to survive long enough to make initial class irrelevant)..... Archaeologists are also good because gem identification (makes it easy to buy the good equipment0..... Wizards are tough early on until you can gain some strength and good equipment.

    We have Karaoke Revolution games, but they are a lot less interactive (they are all just la la la, nothing to actually DO). Rock Band is great because (up to) four people can be playing *At The Same Time*......and it's physical. For Karaoke Revolution, we always finish in the exact same order:
    My oldest and My wife can both sing and finish at the top (virtual tie)
    My yougest is next
    The middle daughter is next
    And then me (I'm a programmer, I can't sing).

    In Rock Band, there's actually competition (ooo, I got 96% to your 94%) that varies by who is playing their strongest instrument. And because it also has a Group vs System dynamic, you don't mind being the "worst". But they are girls that like Pop, so even if the songs are popular, they aren't popular in my house.....therefore, the need for a Pop Band. And sure, they may use a limited note set, but game designers should be able to come up with something else.....even if the orange fret just controls the stage effects.

    ---This "cloud" is nothing other than the use of browser-based applications were all the hard processing is all done centrally on the server and the browser is merely the graphical interface.

    I thought the cloud was this mythical Web 2.0 type thing where it was multiple servers each providing a little bit of functionality and they were combined into a cohesive functional unit either on yet another server or directly in the browser. The cloud term would refer to how a cloud is made up of little drops of water that individually just look like water and just stands on its own, but when you step back, it looks like this single amorphous entity that is a cloud.
