  1. vast energy required on Sea Level Rise Can't Be Stopped · · Score: 2

    creates even more CO2 with our current energy generation

  2. next Carrington Event will make this trivial on After Recent US Storms, Why Are Millions Still Without Power? · · Score: 1

    A repeat of the super solar storm may take out power in most of the world. It may fry most satellites and computers too. It may takes months if not years to restore power then. Some ice core evidence suggests such storm happens about once per 500 years.

  3. short for "O my God, I better find it" particle on CERN Announcing New LHC Results July 4th · · Score: 1

    If you spent ten billion, you better find it too.

  4. gravity is too weak to interact subatomic scale on CERN Announcing New LHC Results July 4th · · Score: 1

    The other tree sub atomic forces are at least 10^38 times stronger. Atoms are mostly empty space. It would be very rare for the black hole to get close enough to another particle to absorb it, much less a cascade of particles that would really enlarge a black hole. And particle size black holes evaporate very quickly.

  5. SpaceX will fly circles aroudn them on NASA'S Orion Arrives At Kennedy, Work Underway For First Launch · · Score: 4, Insightful

    Even though SpaceX is only a candidate for the low-orbit (space station) manned program and Orion is for deep space, I would not be surprised if SpaceX does so well they are considered for deep space too.

  6. Apple should close its stores in China on Apple To Pay $60 Million Over iPad Trademark Dispute · · Score: 1

    They should move the factories too, but Apple is too entrenched. The Chinese would still be able to get their iPhones the old way by mail order or US agents.

    Customers in China account for 12% of Apple revenues. This may double soon as their demand is insatiable.

  7. new Chinese premier's family has billions on Apple To Pay $60 Million Over iPad Trademark Dispute · · Score: 5, Informative

    Chinese leadership wealth makes Romney look "middle class" in comparison.

  8. Neandertal DNA is much older on Oldest DNA Recovered From 7,000-Year-Old Skeletons In Spain · · Score: 2

    And more detriorated. But shot-gun fragment analysis has recovered over 85% of a Neandertal genome. Enough to make detailed analysis to say how its related to homo sapiens.

  9. "one in a a trillion" event on CERN Announcing New LHC Results July 4th · · Score: 5, Informative

    During a run they record billions of collisions and terabytes a day. Even so that is just a tiny fraction of so-called "interesting collisions"; most routine data goes unrecorded. Over the months they have recorded trillions of collisions, each which represents the state of several thousand detectors. Then they search for Higgs decay candidates off-line. There are several potential decay patterns, so the search may be done multiple times. Last year's "hint" of the Higgs was 3-5 anomalous events at a likely energy at two colliders. They'd like at least a dozen, for 4 to 5 standard deviations above the noise before they call it a new particle. This is searching for one significant event on average out of each trillion recorded.

  10. didnt even have devkit the first 9 months on On the iPhone and Apple's Meteoric Rise To the Top · · Score: 3, Interesting

    I remember hackers jail breaking the thing to expose the underlying Mac UNIX. Opening it up to 3rd party developers was an uncertain but profitable move.

  11. trustworthy 3rd party to verify currency on A Cashless, High-Value, Anonymous Currency: How? · · Score: 1

    Right now a organization like MasterCard or a Federal Reserve Clearing House verifies the electronic certificates shuttling through cybersapce. i am not sure I'd trust a distributed verification like in bitcoin.

    But the trouble with trusted 3rd party is that they can collect information about the transaction. Then it isnt anonymous.

  12. early internet, and Mintel were telephone lines on France Ending Minitel Service · · Score: 1

    Although a landline could go as high as 56 kbits, you usually got half of that. This was OK for text-rich pages. But totally inadequate for the graphics and video rich web of today.

  13. Alaskan Pipline may have to shut down on Oil Exploration Ramps Up In US Arctic · · Score: 4, Interesting

    I heard below 20% capacity or about 400,000 barrels a day it can become unsafe to operate in the winter. Its down to about 500,000 now.

    I drove along the pipeline road from Valdez to Fairbanks 6 years ago. Its an amazing thing to see,

  14. ocean has 100 meter hills & valleys due to gra on U.S. East Coast a Hotspot of Sea-Level Rise · · Score: 1

    Here is a map of these sea level variations. A large hole in the Indian Ocean is probably related to the convection cell jamming India into Asia.

  15. link to the tomography experiment controversy on U.S. East Coast a Hotspot of Sea-Level Rise · · Score: 1

    This experiment happened early in the web era, so there is not a lot of material on line. See the marine animal paragraph near the end.

  16. satallite altimeter better for GLOBAL sea level on U.S. East Coast a Hotspot of Sea-Level Rise · · Score: 4, Informative

    The TOPEX satellite has been measuring the whole ocean surface for 18 years and found it has risen about two inches at a very even rate of increase. Various scientists attribute about 80% of this to thermal expansion of warmer oceans and the rest to melting ice. Although the ocean surface temperature appears to to have gone up a bit, that may bot be indicative of the total thickness of the ocean. The best proposed temperature experiment- measuring the speed of sound half around the world- has been tied in environmental litigation. The sound source might hurt marine animals hearing is the claim. The sound source is not an explosion, but a distinctive wide-frequency chirp that can be integrated at the receivers over a period of hours. This experiment would be repeated every few years to look for changes in sound travel time, which would show temperature changes of water velocity.

    Local tidal guides or GPS would be affected by vagrancies of local land level changes, which are rather common. This ranges from ice age rebound, sediment deposition loading, sediment erosion unloading, and even a bit of tectonic rise in the Appalachians. And this Nature article says the pattern of water circulation in a region can change locally too, contribution to an apparent LOCAL sea level change.

  18. "defense advanced research project" DARPA on How the Militarization of the Internet is Changing Warfare · · Score: 2

    Part of the goals was a distributed network with no "head" could be knocked out in an attack. The 14 root name-servers are the closest thing to a head.

    I remember before there were hierarchical name servers, we kept the list-of-the-internet on each of our computers and updated it weekly. Above about 10K names its got cumbersome.

  21. will swiss survive diversification? on Are We Failing To Prepare Children For Leadership In the US? · · Score: 0

    They've been a fairly homogeneous culture for several thousand years, protected by survivalism in the mountains. But there have been some protracted disputes about construction mosques in the cities.

  22. Apple store: affordable uniform on Apple Store Employees Soak Up the Atmosphere, But Not Much Cash · · Score: 1

    Apple is chinos plus one of their store shirts. Tiffany's you have to dress upscale, go to the cleaners each week, etc.

  23. Kepler may tell us what is "normal" on Kepler-36's 'Odd Couple' Defy Planet Formation Theories · · Score: 2

    It was modeled that one in two hundred solar systems would have the proper orientation to generate transits viewable by Kepler. That would mean as many as a thousand solar systems in Kepler's 150K star aperture. From these we should get a model of what is typical and atypical.

  24. like Steve Jobs security clearances to sell Pixars on 'Nuclear Free' Maryland City Grants Waiver For HP · · Score: 2

    When Pixar was still a hardware company making graphics accelerators, Steve sold one to a DOD contractor. He had to get a security clearance to do so. Someone got the clearance data using FOI and posted a couple weeks ago. Both this and Nuclear Free Zones is some extreme government bureaucracy.

    He was hounded into dangerous therapies because of his sexual orientation. Now the largest computer company in the world is run by a gay man. What would Alan had given us with another 20 years?
