  1. Re:Correlation is not causation on Growing Evidence of Football Causing Brain Damage · · Score: 1

    No knives or handguns, but more injuries, from broken fingers to knee reconstruction and the occasional concussion, broken ribs, or internal trauma. It's a true sport. http://www.sandiegolions.com/

  2. Energy Positive on Ask Slashdot: Ideal High School Computer Lab? · · Score: 1

    Make sure any new building is a "net-zero" addition, with LEED Platinum level energy efficiency, and enough renewable energy to make the building energy neutral or energy positive. http://www.usgbc.org/DisplayPage.aspx?CategoryID=19 Include things like SolarTubes for natural light: http://www.solatube.com/ Include lots of plug-trees in open spaces for laptops (that's where you can put plants). Include a secluded quiet zone, for serious programming or study, and a glass walled meeting room for discussions and media development. Personally, I like a library with all the tech manuals, programing books, software manuals, etc. even out of date books give us valuable perspective and unique understanding. Remember you are teaching the spectrum of computer skills, from basic literacy to specialized science, include areas for business, programing, and creative visual arts. (A serious lab for robotics, AI, and smart phone apps wouldn't hurt).

  3. Still Catostrophic on Climate May Be Less Sensitive To CO2 Than Previously Thought · · Score: 1

    Assuming that this new data is dead accurate, as we have already doubled pre-industrial levels of CO2 (from under 200 ppm to nearly 400 ppm today), and temperature has already risen 1-degree Celsius over the past 100 years, we can expect to see 1.6 degrees Celsius (2.9 degrees Fahrenheit) increase in average temperature across the biosphere in our lifetimes, presuming we immediately stop adding extra carbon to the atmosphere. Last time that kind of change happened we had an ice age. Of course that happened over a few million years, not a few hundred. I guess melting the polar caps, raising the sea levels, and killing off 1/10th of the species on the planet isn't too bad a price to pay for the fun we have with monster trucks. Hey, I'll be dead by the time the glaciers hit California again anyway, guess your kids will deal with it. Then again I could be wrong. I hear they have been scientifically measuring evaporation around the planet for hundreds of years, and that since 1950 we have seen a large decrease in sea level radiation due to particulate matter in the upper atmosphere reflecting and absorbing then radiating energy into space. Kind of a global sun-screen from industrial carbon pollution and agricultural land use. Imagine how much more temperature rise we would have in the seas if that solar radiation hadn't been blocked? ... I wonder if this study accounted for that? Hmmm... but that says nothing about the Ocean Acidification that is taking place, upsetting the balance of life in our oceans globally. There is just so much we don't know. Better just keep on doing what we have been doing until we can see an unquestionable result, kind of like a global chemistry experiment. http://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's_atmosphere http://en.wikipedia.org/wiki/Ocean_acidification http://en.wikipedia.org/wiki/Global_dimming

  4. Re:Einstein replied "Check your measurements, son" on CERN Experiment Indicates Faster-Than-Light Neutrinos · · Score: 1

    I'm sure that someone else at LHC thought of this, but you can't send radio signals through the earth like neutrinos. So the distance from the control mechanism to the antenna on the top of the building, should be about, say, 18m, right? (plus any curve in the earth's surface, assuming that the receiver is over the horizon.) This really sounds like an error in measurement, repeat with a receiver on the moon.

  5. Re:Not random and not predictable? on Scientists Develop Financial Turing Test · · Score: 2, Interesting

    It means it follows a recognisable pattern, that can be distinguished from random data after the fact but not predicted in advance.

  6. Typing be allowed to evolve or die. on The Case For Mandatory Touch-Typing In High School · · Score: 1

    Typing should not be 'mandated' by public schools. This is an inefficient from of communication. QWERTY is DESIGNED to be INefficient. With Voice to Text technology, and Text to Voice, AI's getting better all the time, and the use of video-telephony and other multi-media, typing is becoming ever less relevant and will eventually be replaced by some new technology. Typing should still be an elective in High School, but never a substitute for learning long hand writing skills in elementary school.

  7. Not-for-profit on The Ethics of Selling GPLed Software For the iPhone · · Score: 1

    For the CopyLeft software, the original should set the standard. To be true to their concept, you must not charge for this game. If your intention is just to cover costs, then ask for donations. Perhaps, you could publish a free version of the standard game, then publish an upgrade to your top version for $3. Divide your work from the original. Your project should be set up to sustain the game, but not profit off the original author's code. The concept of GPL and GNU/copy-left is to create infinitely useful tools that cost nothing.

  8. Re:It's not possible even in theory on Encrypted But Searchable Online Storage? · · Score: 1

    Agreed. But like any good fiction, if this magic were miraculously plausible, the possibilities would be amazing. It would guarantee free speech forever, make money laundering a meaningless exercise, and create un-copy-able data. True freedom and real secure intellectual property are not dreams easily dissuaded.

  9. Re:You want to... on Encrypted But Searchable Online Storage? · · Score: 1

    Wouldn't this depend upon the bit length of the encrypted string. Because, as I understand it the common public key encryption algorithms use repeating periodic "chunks" and use the value of these "chunks" of data, to help randomize the code. Essentially each "chunk" of data is randomized differently, forcing you to decrypt the whole database in order to search it.

  10. Re:There is a way, kind of: PIR on Encrypted But Searchable Online Storage? · · Score: 1

    Wouldn't that set up require the searcher to share a private key with the server in advance, and send that same key (encrypted with a public key) every time? Essentially negating the ability for blind searches, because the server uses the private key to break the private key encryption locally, then uses the public key to return the results, which can be viewed by the searcher.

  11. Re:It's not possible even in theory on Encrypted But Searchable Online Storage? · · Score: 1

    You're still not searching the data, so unless the index has been carefully set up with a set of key words for each article or page, then you will miss search terms, and it will never be as good as a Google AI search.

  12. It IS Reasonable on Testing IT Professionals On Job Interviews? · · Score: 1

    You are all wrong. Not only is it reasonable to TEST people on a job interview to make sure they have the competency that you require, it is imperative, especially in the case of homeland security and other life and death situations (like commercial banking) so that you don't end up with the kind of situations that are common under the current president. Imagine if we gave our elected officials a test to see if they understand the US Constitution. If you hire a lawyer, a doctor, a IT Pro, then test him. Otherwise you are the fool.

  14. Re:Its pretty simple, really on Brain Study Calls Free Will Into Question · · Score: 1

    Misconceptions...

    Determinism-
    "- Completely determined process, action -> reaction."

    The historic mistake in our thinking is presumption of the "CAUSE -> EFFECT" (action-reaction) concept at the center of much of science and engineering. It seems very reliable at our Macro-level of Newtonian experience of the universe, but with the developing relativistic Micro-level (Sub-atomic) understanding of underlying quantum type foundations, we begin to see that the appearance of large scale stability is actually just the statistical averaging of trillions of unstable fluctuations.

    However, your dialectic counter statement:
    "- Completely random process, governed by random quantum effects."

    This is also incorrect. As I understand it, quantum processes are not truly RANDOM, they are probabilistic, altho the probabilities apparently fluctuate due to complex forces across unlimited distance on time scales so small that the complex effects seem RANDOM, and may be undeterminable.

    Therefore the proper perspective might be to think of the PROCESS OF CREATION as an ONGOING enterprise or ETERNAL event, with an infinite infinity of virtual possibilities condensing into our experienced reality at each moment. This is a BLOCK form of the "MANY WORLDS" Thesis, an infinite number of possible universes, and our conscious experience a path among them. This perspective not only leaves room for a type of FREE WILL, it also explains the seeming flow or ARROW of TIME. The "other worlds" are inaccessible or virtual to us, except as our actions take us toward or away from them as we 'move' through time.

    I predict the brain is much more complex than we suspect even now, but if this experiment is accurate, it only shows what we already know, that our conscious perceptions (even of our own consciousness) lag behind the actual events.

    We live our lives in the past using memory, only perceive the present after it has happened, and predict the future only by inference and inductive logic, which is totally dependent upon our natural genetic ability to reason combined with our nurtured abilities as programmed by individual experiences. The fact that we perceive our will as free is due to the reflective nature of our consciousness, the brain's ability to model our universe, including itself and our 'selves', and then proactively adjust our thoughts/brain/actions to choose those probable futures we most desire. The only limitations on this type of free will is the accuracy of the models and the efficiency of the predictions, i.e. education and intellegence.

    Is that clear? If I can't even tell if I'm making sense, how am I supposed to be free? OK, I try again.

    We can have free-will, the ability to choose our future path through our thoughts and actions (or inactions), even if our brains react to what has come to be, because their are an infinite number of possible universes and our consciousness are such that they move through time and our individual potential future paths are apparently undetermined (do to ONGOING PROCESSES OF CREATION). By accurately modeling reality, we can predict where we are headed, and thus effect our individual actions (including thoughts) to take us in a different direction. From our perspective the choice ripples out through physical effects and seem to change our world, directly and indirectly, creating a future we predicted.

    How much CHOICE we have depends upon the accuracy of our model and our ability to handle the complex variables (i.e. education and intelligence). We may make mistakes or move randomly out of ignorance, especially at first, but given enough experience data we can usually predict at least general probabilities instinctively, if not specific outcomes.

    Interestingly, from an eternal perspective, such as many spiritual traditions proclaim, the "World Path" of any individual is just one version of the possible. As from this perspective we each essentially create a universe through our choices, but only experience
