  1. Re:The REAL value of the transit system on Cracking Atlanta Subway's Poorly-Encrypted RFID Smart Cards Is a Breeze, Part II · · Score: 1

    Thats one of the most moronic statements I have ever seen.

    Aside from the whole "its already subsidized" thing, people bought those cards because they were cheaper, not because they were at some magical "correct" price point.

  2. Sounds like bad methology on Is Time Moving Forward Or Backward? Computers Learn To Spot the Difference · · Score: 2

    You tube videos? And analysation on block level?

    Won't the fact that the video codec has a direct timeline (with predictive frames, etc) override the rsults?

  3. Re:Lead is mentioned some 16 times on How LEDs Are Made · · Score: 1

    When was the last time you have seen somebody use a soldering iron with has mask and gloves? In contrast to europe, american solder is still lead based.

  4. Re:Somewhat off-topic: why not uncut LED panels? on How LEDs Are Made · · Score: 2

    They would be too bright, and too expensive. Those 5mm LEDs (outdated crap) have LED dies of a less than 1/20th of a mm^2 inside.

    High-end power LEDs that put out the equivalent of a 100W incan bulb are 2-4mm^2.

    A disk the size of a traffic light would be able to draw 10000s of Amps, and be bright enough to illuminate a stadium (if you could drain the waste-heat away). Driving it with lower currents would be a collosal waste of dies.

    So the wavers are cut into conveniently sized pices that have reasonable power draw and thermal conductivity and then later are put together according to the requirements.

  5. 25 year old technology on How LEDs Are Made · · Score: 1

    Not just the production way is low-tech, this type of LED is depricated for everything but the cheapest crap available.

    Modern LEDs are basically all SMD, the high power ones typically mounted on a solid metal core PCB. And those are acutally manufactured in a more modern type of way.

  6. Re:volume on Why Tesla Really Needs a Gigafactory · · Score: 1

    There isn't that much to gain from economy of scale, as those types of cells are already produced in 100s of millions per year. So we are realistically looking at something like halfing the price at most, not cutting it down by an order of magnitude or something.

  7. mAh is only half the equation on Sulfur Polymers Could Enable Long-Lasting, High-Capacity Batteries · · Score: 2

    What matters, in the end, is the amount of energy a battery can store.

    With Lithium Sulfur cells, the voltage is a little more than half as high as for Lithium Ion batteries, so the initial advantage is not as large as it might seem from the mAh numbers.

  8. Re:Programming is over-hyped as a career on Will Peggy the Programmer Be the New Rosie the Riveter? · · Score: 1

    Also, didn't Rosie the Riveter quite after a couple weeks because the job was too dirty and dangerous?

    Seems like a bad goal to set...

  9. Re:What do the humans actually do on a ship? on Rolls Royce Developing Drone Cargo Ships · · Score: 2

    Oh, yeah, you COULD do it.
    If you overengineered the ships (making them 5 times more expensive) AND had complete checks agter every 1000 operation hours of everything (which is basically every round-trip for a container ship).

  10. Re:Impressive. on Tesla Model S Can Hit (At Least) 132 MPH On the Autobahn · · Score: 1

    Wrong. Per default, Autobahn has not speed limits.

    Unless indicated otherwise, if you enter the autobahn, NO LIMIT.

    Yes, there are speed limits quite commonly, but if you discount Stadtautobahn stuff and the Ruhrpott, 2/3rds of it are unlimited. Case in point: You can drive Stuttgart/Berlin and have all but 50km or so of the distance unlimited.

  11. Re:Great... on 6TB Helium-Filled Hard Drives Take Flight · · Score: 1

    In theory. In practice, helium will interact with, for example, iron alloys (steel), ending up with de-electonized protons migrating through the bulk metal, and at the other end snatching up some of the fermi-gas and going their merry way.

    The same way, in vacuum systems, getting rid out of the stupid hydrogen magically appearing out of nice stainless steel enclosures that have been ultrasonic cleaned and baked under vacuum is a real problem. I have seen suggestions of burning the whole chambers under vacuum at 650C to get the protons out, and even that isn't really the end of things.

  12. Re:Expensive Apple on Smartphone Sales: Apple Squeezed, Blackberry Squashed, Android 81.3% · · Score: 1

    How the hell do you get a 15k phone bill?

    And why are you bragging about your stupidity to not get a contract to accomdate your usage profile?

  13. Re:Uses of Java applets on Firefox's Blocked-By-Default Java Isn't Going Down Well · · Score: 1, Insightful

    Are you posting in Bizarro land?

    Your own link tells us that over 91% of the users of chrome didn't even encounter a SINGLE java applet in a whole MONTH.

    Thats an absolutely overwhelming sign that java is almost extinction-level rare in the web. Hell, I would bet that the rate of people encountering embedded MIDI files was much higher.

  14. Re:Sacrilege on Boeing Turning Old F-16s Into Unmanned Drones · · Score: 1

    The F16 was always the bargain bin little sister of the F15 (the "real" fighter jet).

    Its main appeal was that it was _cheap_, not that it was good.

  15. Re:I seriously like my Surface Pro tyvm on Why Is Microsoft Setting More Money On Fire With Surface 2? · · Score: 1

    Obviously that comment IS needed and insightful, seeing all the mouth breathers who cannot tell about the RT from the Pro.

  16. Re:Not being well reviewed ... on Why Is Microsoft Setting More Money On Fire With Surface 2? · · Score: 1

    People cry about 900g being heavy, but try to find a laptop of that size thats even remotely as capable. Even the smallert Macbook air is heavier, and its inferior in every single way.

    Plus the docking station with 4k capable video out should take care about it anyway.

  17. Re:Ah slashdot bias.. on Why Is Microsoft Setting More Money On Fire With Surface 2? · · Score: 1

    Ah, right. Because nobody cares about an order of magnitude speed difference.
    Because all those nice, docile consumers in their walled google/apple gardens don't need to MAKE anything, and media decoding is done in hardware codecs.

    I guess your office is stuffed with professional web-browsers?

  19. Re:Conspiracy theory: Bitcoin crash of April 2013 on US Mounted 231 Offensive Cyber-operations In 2011, Runs Worldwide Botnet · · Score: 1

    If the US wanted bitcoin gone, they could have done so.

    There exists something called an "51% attack", which means that anybody having more than half the hashrate of the Network is acknowledged as the boss and can do as he wants (stuff like spending the same bitcoin multiple times, manipulate the difficulty of future block mining, etc).

    Back in April, before mass ASICS, the US could have trivially gotten that far. Hell, last year anybody willing to spend 5-10 million could have done it with off-the-counter hardware.

    For an agencies who have a double digit BILLION black budgets, this is totally peanuts.

  20. Re:Those magnets sure were fun on U.S. Gov't Still Fighting the Man Behind Buckyballs; Guess Who's Winning? · · Score: 1

    I don't think its disturbing to be able to buy them "so easily".

    I mean, seriously. You need a credit card or paypal to buy from them, so you are no infant in the "I eat metal stuff" phase.

    And secondly, you have dozens of way more deadly things in your appartment at any time, anyway.

    DX made a new site just for their lasers. I think the name is yourlaser.com or something.

    IIRC, they did this because custom troubles for the main DX stuff,even if their were no lasers, got out of hand, in particular in australia.

  22. Re:Sooo.... on Cold War Plan Tried To Put a Copper Ring Around the Earth · · Score: 1

    No, it did NOT work as planned. Because those dipoles were supposed to de-orbit after a few months.

    Instead, a significant part is STILL up there.

  23. Re:20 min of fun on BMW Debuts First Electric Vehicle Made Primarily of Carbon Fiber · · Score: 1

    You might not realize it, but I would bet a lot of money that 90% of the time, you are using less than 20% of the power your car has.

    Seriously. If you have a 200HP car, it will do that if you floor the pedal a bit below the redline. Normal driving? It takes maybe 15-20HP to keep a car moving at 70MPH on the highway.

  24. Ain't it nice on Yahoo Receives Special Recognition For Fighting For User Data Privacy · · Score: 4, Interesting

    This is just like Kafkas "Der Prozess".

    You got secret laws that people/companies are ordered by a secret court to be followed, and they are not even allowed to tell anybody about it.

    Land of the free.
