  1. Usefulness limited? on Obama To Get Secure BlackBerry 8830 · · Score: 2, Interesting

    but only to those with the secure software loaded on their own devices

    How useful is the phone then really, if you can not even call the dry cleaners down the street? Or maybe Obama only communicates with 5 or so people?

  2. Re:What copy? on Copyright Lobby Targets "Pirate Bay For Books" · · Score: 1

    Maybe the publishers are so greedy, BECAUSE they have to pay the lawyers!

  3. Cost on Robotic Penguins · · Score: 1

    The head (almost an arm) movement of the artificial penguin is extraordinary - a very elegant design. It must be cheaper, lighter and more robust than a "normal/classic" jointed arm.

  4. Progress in theoretical physics on Quantum Setback For Warp Drives · · Score: 2, Insightful

    This is best guess at the moment. We don't have a unified theory of everything proven and in the bank. We are not yet even sure how many dimensions the universe is constructed out of (the total varies between 4 and some large number every month). So it is an improbability with current physics knowledge versus a distinct impossibility (a small but significant difference in argument)

  5. Re:DANGER DANGER on American Airlines To Offer Wi-Fi In Planes · · Score: 1

    and the cell phone and network will go crazy in switching.

    Exactimo, typically the mobile phone base station on an airplane includes a jammer. The noise floor is raised on all the cellular bands except the airplane's base station channel, forcing the mobile phone to connect to that channel. It therefore takes the least RF power for the mobile phone to connect to that particular channel.

  6. AC vs DC on The Underappreciated Risks of Severe Space Weather · · Score: 1

    As far as I understand, the changes in the earth's magnetic field induces a current in the long conductors of the grid via the process of magnetic induction. Unless I have the wrong process pegged for this phenomena, should the current induced due to the changes in the magnetic field not be an AC current instead of a DC current (as stated by the article)? Or is the induced current so slowly varying that it can be considered DC from the point of view of the power grid?

  7. Re:Learn how to learn on Proposal Suggests UK Students Study Wikipedia and Twitter · · Score: 1

    This web-related teachings should not replace anything like history, but should be in addition to the normal curriculum. The amount of time people spend on education are steadily increasing as the world we live in gets more complex. We might cast the web out a bit wider than just Twitter and Wikipedia, and teach them how to use the web safely, e.g. what are the privacy implications when you open up your profiles, ideas and rants up to the whole world on facebook. Or how to use search engines efficiently, or teach them a program language. Computer literacy and internet literacy should be compulsory in this day and age.

  8. Re:Productivity on Companies Waste $2.8 Billion Per Year Powering Unused PCs · · Score: 2, Insightful

    No, because logging on, firing up applications and development environments, opening any projects/files that you are working on takes time. Say conservatively 10 mins per day. That is 50 mins per work week. That is almost an hour of my time a week - already exceeding the cost of the energy (depending on your hourly rate of course).

  9. Speed vs. generalisation on Microchip Mimics a Brain With 200,000 Neurons · · Score: 1

    From the article: "The reason why computers seem much slower is that they are serial machines, while our brains run in parallel"
    Computers are definitely faster than humans doing focused tasks, like computing a 1024-point FFT or inverting a 1000x1000 matrix.

  10. Re:Chrome only browser ... on All Five Smartphones Survive Pwn2Own Contest · · Score: 3, Insightful

    Chrome is also one of the newest browsers in the market. The longer a browser is out there, the longer the time someone can develop a hack for it. I bet for the next contest, presuming that Chrome will still be around, there will be a few Chrome hacks to go around.

  11. He who controls the bootloader... on Researchers Demo BIOS Attack That Survives Disk Wipes · · Score: 1

    Controls the everything about the machine...
    Every flash upgradeable BIOS needs a monitor program to upgrade the BIOS itself. Typically that monitor program resides in a separate block in flash and is rarely updated (depending on the programmers, of course!). Putting this monitor program in ROM would allow you to solve this and always allow you to update the BIOS.

  12. Cambridge (UK) on Places Where the World's Tech Pools, Despite the Internet · · Score: 1

    It is the British version of Silicon Valley (called Silicon Fen) , and is certainly much more prominent than Romania. ARM is probably the most famous of the Cambridge-based companies.

  13. Price vs. Efficiency? on Building Your Own Solar Panel In the Garage · · Score: 3, Informative

    The panel in the article produced 17 Watts, for a panel size of about 1m x 0.5m (approximated from photo with mobile phone in it). A quick google reveals a 43W polycrystalline panel of similar size for about 300 euros (about 7euros/watt peak)

  14. Seed the solar system/galaxy on UV-Resistant Micro-Organisms Discovered In the Stratosphere · · Score: 1

    1. Cross these UV-resistant bacteria with these http://en.wikipedia.org/wiki/Deinococcus_radiodurans> radioactive-resistant bacteria.
    2.Blast them towards the planets/exo-planets
    3.Let life take hold

  15. Cryptodiagrams on Australian Gov't May Employ a Homegrown Quantum Key System · · Score: 1

    I guess Alice and Bob http://en.wikipedia.org/wiki/Alice_and_Bob were replaced in the design document with Sheila and Bruce!

  16. Gemini planet imager on Exoplanet Found In Old Hubble Image · · Score: 5, Interesting

    Keep them coming! One more place to point the Gemini planet imager in 2010 http://gpi.berkeley.edu/index.html
    Once we can do direct imaging, we can sample the planet spectra, and determine the atmosphere, composition, etc.

    a. Journalists

  19. Re:A problem for AMD? on Intel Moves Up 32nm Production, Cuts 45nm · · Score: 1

    You mean being only one step behind instead of two?

    No, AMD's processes uses strained silicon, that is faster than normal silicon.
