  1. Re:So if I'm reading this right ... on iPhones Can Read Tattoo Ink For Medical Info · · Score: 1

    Well, when they're tattooed with special fluorescing nanoparticle ink they do

  2. Very unimpressive demo video, keys easily visible on Exploiting the iPad's Glowing Keyboard · · Score: 1

    That has to be one of the least impressive video demonstrations I've seen, it probably would have been quicker to frame advance the video manually and type the easily visible key presses by hand.

    If this program could decode key presses from further away where keys are no-longer easily distinguishable by eye then I would be impressed.

  3. Re:Thank god on Bitcoin Mining Tests On 16 NVIDIA and AMD GPUs · · Score: 1

    Yeah bitcoins definitely looks like it's suffered a bubble, but if bitcoins is used properly there is no need to "find new investors" (ala pyramid scheme) as you are principally using it as a free money transfer medium, not just as a way to make more money.

    I just spent £120 on a new 5870, if it can pay for itself in bitcoins I'll be happy.

  4. 90% figure is bollocks. on Scientists Breeding Super Bees · · Score: 1

    bees pollinate 90% of the world’s food crops

    Bullshit. The most important staple crops like rice and wheat are wind pollinated, at most 30% of world food output depends on bees (the highest figure I could find, the lowest was 6%)

    The main effect that losing bees would have is that a lot of fruits, such as apples, would die out.

    If you're that paranoid that every article about biological research makes you worry about "I am legend" scenarios or clouds of murderous insects, I don't know what you're doing typing on a computer. Skynet and the matrix people! What could possibly go wrong?!?

    Yes what could go wrong if you create a new bee strain that out competes all natural bees, becomes a monoculture and then becomes susceptible to a newly evolved disease that it has no resistance to?

  5. Intentional delayed patent enforcement as defence? on Apple Ordered To Pay $8M For Playlist Patents · · Score: 1

    I can't remember the term for it, but isn't there a patent defence if the patent holder intentionally delays attempting to enforce a patent to maximise damages that invalidates the patent?

    Given the patent was filed in 1996, and this sort of functionality started to appear in audio apps in early 2000, it would seem like a prime candidate for this defence...

  6. Space blanket awning and beach umbrellas on Ask Slashdot: Large-Scale DIY Outdoor Cooling of Cairo's Tahrir Square? · · Score: 1

    I'd suggest anything that can create shade, either making some space blanket awning (something like this perhaps) or try to get hold of cheap beach umbrellas.

    The umbrellas can also be painted with slogans etc.

  7. Inversion of control? on Facebook Trapped In MySQL a 'Fate Worse Than Death' · · Score: 1

    Surely they must have, at some point, refactored their code to use IOC so they can just replace all their MySQL data access classes with another data store, no?

  8. Filed in 2007? Here's some prior art from 2001 on Patent Troll Goes After Notebook Cooling · · Score: 1
  9. Re:Is that all? on Hard Drive Overclocking Competition From Secau · · Score: 1

    what's to stop me from just putting an additional set of heads and control electronics on the other side of the disk

    Err, the engineering difficulty involved? But, you know, if you can just install an additional set of heads and controllers on a hard drive then I guess you've got the prize money in the bag!

  10. Re:Text a One-Time-Password on Sound-Based System Promises Chipless Phone Payment · · Score: 1

    Acoustic coupling means my phone, that I hold against my face, is getting all the germs from all the other phones (and so faces) inserted into the coupler

    You didn't bother watching the video did you? It works long enough distance that it doesn't need to physically touch the device like an old "acoustic coupler" modem (hence "acoustic coupling scheme" for want of a better phrase, not "acoustic coupler").

    It would be insane for every shop to have to install and maintain a femtocell and have front facing screens just so that customers can use a QR code online mobile payment system when there are now several technologies that allow them to just plug a new reader (either NFC or this new sound based system) into their POS system and have their customers wave mobiles in front of it.

  11. Re:Text a One-Time-Password on Sound-Based System Promises Chipless Phone Payment · · Score: 1

    Um, a simple acoustic coupling scheme is sounding a lot simpler to me than setting up and maintaining femtocells and wifi everywhere that shops want to roll out mobile payment.

  12. Re:Text a One-Time-Password on Sound-Based System Promises Chipless Phone Payment · · Score: 1

    QR code on the cash register and cameraphone, already working

    Again, this relies on the customer's phone having a signal. Bad signal and the QR code is useless. The cash register could have a camera, and the phone display a QR code, but that's still only one way communication which limits its usefulness.

  13. Re:Text a One-Time-Password on Sound-Based System Promises Chipless Phone Payment · · Score: 1

    Why can't the phone just text a One-Time Password to the cash register? Or use HTTPS? Or USSD, the GSM infrastructure high priority message used for topping off prepaid phones? Or any of a number of other comms techniques?

    How will the phone get the address of the cash register? All of those ideas would require the user to enter the cash registers details on their phone (time consuming) and if their phone doesn't have signal then the whole thing won't work.

    With this the phone can send card details to the cash register regardless of signal and without the user having to type anything in.

  14. Re:back to capt'n crunch on Sound-Based System Promises Chipless Phone Payment · · Score: 1

    Given the limitations of the cell phone microphone and the network, I would wonder how complex the tone could be.

    How complex the tone could be? It's obviously going to be a modulated digital signal, so they can use whatever encryption protocol they want.

  15. I made a Dreamachine... on 'Dead Media' Never Really Die · · Score: 1

    And what happens when you trash the copyright attribution on a photo from 2010?

  17. Chromium, much? on Mozilla Labs Introduces the Webian Shell · · Score: 1

    The Webian Shell basically consists of a browser which will replace the traditional desktop, and web applications are given more importance than the native applications.

    This idea seems so familiar...

  18. Irrelevant comment on Cheap GPUs Rendering Strong Passwords Useless · · Score: 1

    And any system worth its salt (crypto-hashing joke) won't allow that many attempts against any external or internal authenticator and will NEVER expose its password hashes.

    What an utterly irrelevant comment, obviously you can't GPU-accelerate a remote login, that's got nothing to do with the issue here.

    Fact is data breaches do happen (see Sony) and if you can suddenly brute force a password 300x faster than before that is a very big deal. 10 GPU equipped desktops can now do the work of 3,000 CPU based desktops...

  19. Why don't they just release 2 versions... on TI vs. Calculator Hobbyists, the Next Round · · Score: 1

    A specially marked hobbyist version, and a locked down certified exam version? That way people who want to tinker can get the open version, people who need to use it in an exam can use the certified version and TI doesn't have to play cat and mouse trying to prevent people from hacking it.

    I'm at home you insensitive clod!

  21. Bluetooth also works well for Arduino on Why Google Choosing Arduino Matters · · Score: 1

    It's a nice idea, but only supporting a usb connection? I've already used an Arduino with a bluetooth module to communicate with my android phone over a BT serial connection, worked rather well.

  22. Article is just guessing on Groupon Deal Costs Photographer a Year's Free Work · · Score: 1

    The article's author has no idea what this guy's finances are, what sort of company he operates behind his name etc.

    For all we know he has several staff who handle post processing and a deal with a print house for cheap prints.

    The author literally doesn't know what he's talking about because he didn't actually bother contacting James Corrin to find out why he did the deal, what he's getting out of it etc.

    Is it this one? Or maybe this one?

  24. What about proxy apps? on Google Allows Carriers To Ban Tethering Apps · · Score: 1

    Thanks to the usb debugging it's quite easy to use a proxy server on the phone instead of full tethering. I prefer this as it lets me specify which programs use the internet on the phone so, for example, windows update doesn't try to update over 3G.

    I'd think that carriers can't tell the difference between proxy traffic and regular traffic as it would just appear as an http get request from the phone.

  25. Do we need to hear about this every time?? on Bin Laden's Death Being Used To Spread Malware · · Score: 5, Insightful

    I swear I read this same article every time: "[Insert world event here] being used to spread malware"
