    cutting silicon with laser to cripple it does NOT lower the cost.

    Still better than talking to a hand. Google doesnt listen to the users, they dont even have a place to post any concerns/complaints (probably because there was no way to automate it).

    I think what she meant was "You can't win the lottery if you don't buy a ticket".

    Actually you win lottery EVERY TIME you dont buy a ticket, but only 1 in few hundred millions if you do buy it.

  4. Re:99.97% dropout rate on What Professors Can Learn From "Hard Core" MOOC Students · · Score: 1

    Define dropout.
    I signed up for >30 courses in total. I have 7 certs of accomplishment, all with 95-100% score. The rest I didnt bother doing quizzes/assignments, I downloaded all the videos and learn at my own pace for myself, I dont need any more diplomas.
    I only failed in one class I was doing quizzes/assignments, by 3% (at first they send me cert and said i passed, but later revoked it after recount/quiz fixes or something).

    Im sure I am destroying their stats taking all those courses and not doing any "work".

    Hopefully app acl list will be USER defined instead of app defined.
    How retarded is it for an app to blackmail you for Contact list/messages and phone calls just so you can play a game? How come its the app that decides and has the upper hand instead of the user? How come App can blackmail me and I cant simply REFUSE to give it data?
    I want to be able to define ACLs per application. I dont give a shit what app wants, it can eat a duck for all I care. Phone status? sure, feed it fake USER DEFINED status. I dont need a game to know that I have GPS enabled. You want GPS data? Sure, let me feed N38 53.86205 W77 2.19162.
    Its my phone damnit!

    Yes, but using Mems microphones like those

    20 for $12.

    I dont know the math behind you algorithm, but it might be even possible to directly use PDM stream (http://en.wikipedia.org/wiki/Pulse-density_modulation) from those microphones without converting it to PCM first. At 3MHz per micropfone you can cram 32 mics into 12MB/s stream in a small USB dongle that costs ~$40 to make (as low as $30 in bulk if you mfg in China).

    Tablet is an ideal UI for something like this. If you could modify your code to visualize source of sound like in this /. article it would sell like hotcakes on kickstarter at $200.

    I'm not an EE so I won't pretend to fully understand this particular case but I like it when tech companies reach a bit and try something hard. This may or may not be a good idea but I'm still excited about it.

    Nice.

    One from the article solves sync problems by building an array of cheap ($1 for Nokia ones) cellphone digital microphone modules.
    This is quite brilliant and reduces cost tremendously. All you need is one USB I/O chip with 20-30 IO pins.

    How fast is your algorithm? Could it run on average (2x 1GHz A8) ARM tablet? Is it expendable to more microphones?

    This smells like a perfect kickstarter project - app + USB dongle you connect to android tablet/phone.

    Plenty of A31 around, still If I was shopping for a cheap tabled I would look at RK3188 instead.

    I admit I was misleading. GPU is faster, CPU is slower.
    Rockchip on the other hand wins both cpu and gpu comparison (with crusty overclocked quad mali400) against fastest Tegra3.

    My point was cheap Chinese SOCs aren't about bottom dollar_and_performance anymore. They are still bottom dollar, but performance starts to catch up.

    GPU is not a problem, video decoder (cedar) is, but there is a working open source driver now for A10. There is also a working open source driver for MALI400.
    Both experimental, but nightly builds work ( as good as experimental stuff would)

    Allwinters most popular chip at the moment is quad Cortex-A7.
    Rockchip is another Chinese manufacturer making quad A8 (RK3188)

    Both are faster than fastest Tegra3.
