  1. Not that pricey on Open Source Driver For Microsoft Surface 2.0 · · Score: 1

    The local M$ store at the Mall of America has them for sale for $5000. Looking at the specs, its not much more than it would cost to build a comparable desktop system.

  2. Re:I'd rather a pill I choose to swallow on Nanoparticles Heated By Radio Waves Switch On Genes In Mice · · Score: 2

    I'll ignore the more mundane uses, and the sinister corporate scenarios*. For now just imagine the prison scenario. You don't need to build expensive walls or fences anymore, just a centrally placed and secure RF transmitter. Walk too far away from it, and the specially implanted genes for [bodily function] are turned on or off. Either killing you, or disabling you so you can be dragged back to your cell.

    *Turn on the genius genes from 9-5, turn on the retard genes from 5-9. Smart workers that will do what you want and never leave.

  3. Its propaganda. on Osama Bin Laden Didn't Encrypt His Files · · Score: 2

    From TFA:

    In contrast to his public statements that focused on the injustice of those he believed to be the “enemies” of Muslims, namely corrupt “apostate” Muslim rulers and their Western “overseers,” the focus of Bin Ladin’s private letters is Muslims’ suffering at the hands of his jihadi “brothers”. He is at pain advising them to abort domestic attacks that cause Muslim civilian casualties and focus on the United States, “our desired goal.”

    Out of 6000+ documents, they picked this to release. You don't need a huge imagination to see why.

    Although I do give them credit in making this public and trying to focus attacks back on to US forces. It makes leaving Iraq/Afghanistan a lot easier if you don't have to worry about them killing each other after you leave.

    The largest underground network of pipes (2820 km) [2] and aqueducts in the world. It consists of more than 1,300 wells, most more than 500 m deep, and supplies 6,500,000 m3 of fresh water per day to the cities of Tripoli, Benghazi, Sirte and elsewhere.

  7. Re:What does this help? on FBI Seizes Server Providing Anonymous Remailer Service · · Score: 1

    Maybe instead of solving the crime, it simply stops more threats from being mailed out. Until a new anon-service is found. And in the meantime the person might mess up and reveal themselves.

  8. Power Grab on University of Pittsburgh Deluged With Internet Bomb Threats · · Score: 3, Insightful

    Soon enough someone will catch on that they can really increase their law enforcement power/budget/detail/department, pass some laws, and maybe get rid of some civil rights because of this. If enough people get pissed off enough, they will happily trade some freedoms for making this all go away.

    I'm surprised the TSA hasn't jumped in on this, setting up checkpoints and searching people anywhere they want on campus. Its the perfect situation to lend credibility to their viper program.

  9. Keep your friends close, and your enemies closer. on Mitch Altman Parts Ways With Maker Fair Over DARPA Grant · · Score: 3, Informative

    Seriously, if anything they should have been more cooperative and helpful. DARPA has all the cool toys. Not to mention they can help you do cool things you cant do otherwise. Rockets, lasers, etc.

    And if it doesn't work out, hey, you're in. You now are in a position to affect change and make it run your way, or do max damage (if you so choose).

    Everyone always assumes a homicidal kill-all-humans AI. Why doesn't anyone ever assume a friendly or benevolent AI will turn sentient first?

    Then you get a fog to read your brain and "upload" you into its systems. Then you have a human-sentient-fog. Wouldn't you trade your physical body for a foglet one?

  12. Re:The Twin Creeks information page says 10 cells on Cheap Solar Panels Made With An Ion Cannon · · Score: 1

    No, they took one thick donor wafer and cut it up. So under normal production, that one wafer would make one solar cell. Now that same wafer was cut into 14 wafers. Of those 14, 10 made it all the way to the final step. So they took 1 wafer and made it into 10.

    This is an example of their efficiency. Not a statement of fact that they have only made 10 cells total.

  13. Re:Incomplete article on Cheap Solar Panels Made With An Ion Cannon · · Score: 1

    If you check out the video on their site, they have a robotic system that automatically loads/unloads the cells through an airlock system.

  14. Re:Get ready for....nothing! on Cheap Solar Panels Made With An Ion Cannon · · Score: 4, Informative

    The $/watt number refers to the cost of the PV chips. So it costs them $0.40 to create a chip that outputs 1 watt.

    At $0.40/w you're paying $400 for a 1Kw panel. At that cost it will take 4000 Kwh @ $0.10/Kwh to pay for itself. That's about 2 years if it gets ~8hrs of sun a day. Everything produced after that 4000Kwh is "free", and since panels last for 10, 15, even 20+ years, that's a lot of "free" power. If grid electricity costs more than $0.10/Kwh, then payback is even faster. (I'm assuming perfect efficiencies to keep the math simple, but you get the point)

    We will soon reach a point where not having such predictive capabilities will doom any launched vehicle to a debris collision. Its interesting to think that such a program provides so much space superiority over other nations.

    At the UofMN people walk out with entire desktops; while the people are still in their office. We had one person who was at her desk talking on the phone, with her back to the door, looking behind her out the window. Someone walked in, unplugged her iMac, and walked out with it.

  21. Re:Who's this for? on Indian Government To Track Locations of All Cell Phone Users · · Score: 1

    In India there really are next to no landlines across most of the country. So its cell phone or nothing.

  22. Re:Governments with Control Issues on Indian Government To Track Locations of All Cell Phone Users · · Score: 2

    Because after the attacks on that hotel, and a few other terrorist acts caused by foreign parties, the Indian government wants a way to track such suspects.

    They can do that already if they know the cell number, but by knowing all numbers and locations at any one time, they can data-mine and compute probabilities of what each cell phone user is doing, relative to both historical and real-time data, and if it is suspicious or not.

    For example, if you see a phone go from a known hideout to another target of interest, you can now track that. Before you would have no way of doing that without knowing the exact phone to track. But when you can see all the phones, you can pick what to follow based simply on where it's been, and then find out who it belongs to. The exact opposite of what they do now.

    Also, in India there really are next to no landlines across most of the country. Yet everyone owns a cell phone, and runs their online life through it. So, you see, it is quite brilliant.

    The optimist in me wants to believe they will also use it for mass transit, infrastructure planning, and health/sanitation. But data sharing like that is unlikely if the system is in the hands of security forces.

    You have a sheet of vinyl that is 30m by 35m. That it weights 800kg (~750g/m2) is quite plausible.

    The paint weights 350kg because it is made out of silver, and they are putting on several coats. The screen has to be very reflective, and silver works best.
