  1. Exponential Birthdays on Turning a Nail Polish Disaster Into a Teachable Math Moment · · Score: 1

    Every time somebody I know turns an age that is a "round" number in my head I get a special nerd-glee. Squares and Cubes do it, for example: 9,16, 27, 64 etc.

    l also enjoy hiding the Fibonacci Sequence in things, just to see who notices.

    On my 27'th birthday I got a "Happy Birthday" message with Fibonacci exclamation points. I was most pleased.

  2. Re:Previous charter subscriber on Charter Strikes $56B Deal For Time Warner Cable · · Score: 2

    Huh... As a previous Charter customer and Current TWC customer, the only good thing I have been able to say about TWC Customer Service is that at least it wasnt as bad as Charter.

  3. Casual Access and Listen to the Users on Ask Slashdot: How Should I Build a Maker Space For a Liberal Arts College? · · Score: 2

    I was a member of the Techshop maker-space here before it folded. The thing that did them in was a lack of casual accessibility, as well as an overambitious start, I think. The way they structured it was to charge large fees for "training" classes to clear you on the use of the various pieces of equipment, after which you were free to use them so long as you were a current member. But it would take several classes and hundreds of dollars to get even a small project off the ground, simply because of the way they mapped out the different class certifications. They were a business so it's expected, and the need for proper safety training is undeniable. But it meant that it took a serious investment before you could accomplish much, and those dedicated enough to do so would generally rather spend the money on their own tools. And on top of that they opened their doors with everything from CNC mills and 3D printers to automotive decal printers to SMB circuit board ovens to metal casting; in other words far more expensive equipment than their user-base actually needed or used.



    At the end of the day, there are two things to strive for, and they wont be easy.

    The first is variety of tools and workspaces. It needs to be a place where people come to tinker and to get some idea out of their heads and into reality. So it needs to offer access to whatever it is that the actual local users are wanting to use. If they want metalworking, get a welder and a few milling machines. If they want woodworking, get some drill presses and chop saws. But dont invest it the cutting edge of everything up front. I recommend some kind of request system, so it can organically grow in the directions the users want. If they see the space is responsive to what they feel they are lacking, it will also go a long way to keeping them coming back, even if they dont have every little thing at first. This will be a balancing game between responsive acquisition and responsible budgeting. Fundraising drives can help, just like a high school that needs a new scoreboard, etc.

    The second is casual Accessibility. Dont make them spend a hundred bucks and take a class that won't be held again for two weeks, just so they can drill a single hole. This is another balancing act between responsible safety and easy access, and the first solution is staff.

    It also really helps to have a large scrap pile for free (or free-ish) materials.

  4. One good turn... on James Watson's Nobel Prize Medal Will Be Returned To Him · · Score: 5, Insightful

    Finally gets another. One guy does something selfless, and another guy does too as a reward. Especially since in an auction he's not just covering the cost, he's running the price up with his participation in the bidding. When everything i read seems to drop Humanity notch-by-notch, it's nice to see something that bumps it up a bit. Kudos Human Race.

  5. Investment? on Factory IoT Saves Intel $9 Million · · Score: 2

    As somebody who designs networks of sensors and controls for manufacturing processes, I want to know what the investment was, and what payback period they are using to calculate those savings. Depending on the size of the plant $9 million might not even come close to covering that kind of mass retrofit.

  8. Re:This is not entirely what it appears in summary on Mass. Supreme Court Says Defendant Can Be Compelled To Decrypt Data · · Score: 1

    Unless I missed it (I know I broke Slashdot rules and actually read the ruling) I dont think he had actually admitted to the crimes themselves, only that he did admit that he was in possession of the Encryption Key. Presumably they already had compelling evidence of the crime itself or they wouldn't have been investigating him in the first place.


    From the Ruling:
    On the day of his arrest, the defendant was interviewed by law enforcement officials after having
    been advised of the Miranda rights. In response to questioning, he said that he had more than one
    computer in his home. The defendant also informed the officials that "[e]verything is encrypted
    and no one is going to get to it." In order to decrypt the information, he would have to "start the
    program." The defendant said that he used encryption for privacy purposes, and that when law
    enforcement officials asked him about the type of encryption used, they essentially were asking for
    the defendant's help in putting him in jail. The defendant reiterated that he was able to decrypt
    the computers, but he refused to divulge any further information that would enable a forensic
    search.

  9. Re:So whats the case law on keys on Mass. Supreme Court Says Defendant Can Be Compelled To Decrypt Data · · Score: 2

    Not quite, but you are making a good point. According to The Ruling the only reason the motion was filed and this issue came at all up was because the guy happened to have used a particularly effective encryption software that the State was unable to circumvent. But they tried and would have been perfectly allowed to use any of the information found had they succeeded. Which is like saying that the 5th amendment would protect the contents of my safe, but only if I can afford a top-of-the-line one.

  10. Digital vs Physical on Mass. Supreme Court Says Defendant Can Be Compelled To Decrypt Data · · Score: 4, Insightful

    I get the legalese argument the guy as trying to make and the narrow line they tried to draw with the ruling, but Im not sure why it even got past the original judge.

    If it had been the exact same situation, just a combination lock on on physical file cabinet in his office, once a proper court subpena was issued Law Enforcement might have asked for the combination as a courtesy but would have been perfectly within their rights to simply cut the thing open. And if they found evidence of some unrelated crime, that is long been fair game just like a drug bust during a traffic stop.

    Maybe it's different by State, I dont know

  11. Nothing to do with "Liberating form Power cords" on Step Toward Liberating Electronic Devices From Their Power Cords · · Score: 2

    This "new" supercapacitor has nothing to do with liberating devices from Power Cords. Supercapacitors still need to be externally charged. All this development does is make them a bit more resilient than current model when in more rugged environment, and supposedly make it where we used supercapacitors as structural components. In other words your car would not have a separate battery to replace, because it's frame itself would be used to store electricity. While the creator seems to think that is the wave of the future, I dont see it as a particular good (or cost effective) idea.

  12. And Fire qualifies for many definitions of Life on Physicist Unveils a 'Turing Test' For Free Will · · Score: 5, Insightful

    The fact that a smartphone (Or I assume by extension any personal computer) can qualify should be an indcator that the test itself is flawed. Just like how many early definitions of Life applied to Fire (breaths, eats, grows, responds to outside stimuli, etc) even though it is just a chemical reaction.

    Wow, bullying, in the boy scouts? I'm utterly shocked. Who would have though an organization full of teenage asshole testosterone pumps would be susceptible to bullying?

    Just because the national management is regrettably old-fashioned and very very conservative does not mean the youth themselves are assholes. At that age they more often actually live up to the public Ideals.

  14. Re:A gift for those skipping out on their contract on Obama Asks FCC To Make Carriers Unlock All Mobile Devices · · Score: 1

    The contracts that the rest of the world think are a ridiculous and counter-productive system?

    Besides, this would have nothing to do with contracts. It just means that if you want to change carriers, you would be able to take your phone with you. IF you hadnt yet paid off the subsidy, they would probably bill you for that when you left, not force others to pay for it. And if they stiff the company on a contractually obligated fee they will most likely find themselves in court or have bill collectors harassing them, just like with every single monetary contract in the country.

    Apple was "more than a little troubled that AppGratis was pushing a business model that appeared to favor developers with the financial means to pay for exposure."

  18. Invented Conenctions on School Shooting Prompts Legislation To Study Violent Video Games · · Score: 4, Insightful

    Saying this man killed his mother and then a bunch of children and teachers because he played video games is about and logical as saying he did it because he ate fatty foods, so we need shut down all McDonald's. There is no link whatsoever, beyond the fact that somebody wants to milk the events and the heightened emotions it is generating for their own crusades. Tighter gun control would not have stopped a determined and unstable man from stealing guns to go killing. Even if there had been no guns, Im sure he could have found another way. Hell, this was the 2nd deadliest elementary school killing because the deadliest used a bomb.

    This really is getting ridiculous. I am getting really tired of all the politicians and lobby groups trying to spin this tragedy to their own agenda.

  19. A step on Accelerator Driven Treatment of Nuclear Waste · · Score: 3, Insightful

    Its a step in the right direction, but it wont gain any sort of sustainable foothold until the technology can get the half-life of the waste down to within a single lifetime. In truth, what it really needs to accomplish is a technology that actually breaks even: something that reduces the stockpile at at least an equal rate to what our nuclear power use is producing.

    Either that or productive Fusion, which does not produce near the lasting Radioactive waste.

  23. Maximum Exposure on Ask Slashdot: Teaching Chemistry To Home-Schooled Kids? · · Score: 1

    If you want to keep him interested and enthusiastic, expose him to as much chemistry as you can, while educating his teachers. Buy him chemistry sets and beginner books, and have his parents research more advanced things so they can accurately answer his questions as they come up. Take him to Science museums, the hands on kind if you can. Look for summer programs and other focused "day-camp" style STEM programs, im sure you could find some that have a chemistry focus. Even just taking him on tours of nearby chemical manufacturing plants could spark his interest.

    Just remember it is your job to assist and guide, not force them to pursue something even after they loose interest (should he do so). I had parents that tried to do that with piano lessons, and it eventually turned into the worst chore i had all week.

    Id also recommend getting him involved in some educational social programs, like the Boy Scouts or similar. The merit badge programs are what got me interested in all sorts of things as a kid, and these days they have badges for modern technical stuff Chemistry and Robotics and Programming and the like, not just knots and wilderness survival.
