  1. Re:The TRUE test on Bell Labs Break Record With 31Tbps Via a Single 7200km Optical Fibre · · Score: 1

    The station wagon can outrun a backhoe.

  2. Re:simple load on Cray X-MP Simulator Resurrects Piece of Computer History · · Score: 1
    You need a 3 phase load. That is going to take some careful bolt placement to get the 3 phases matched.

    Remind me never to visit your neighborhood.

  3. Where is the power load? on Cray X-MP Simulator Resurrects Piece of Computer History · · Score: 1

    For the complete simulation, you need to use a generator load tester to burn the 100 or so kilowatts that the machine used.

  4. 100 million licenses sold, but to whom? on Microsoft Prepares Rethink On Windows 8 · · Score: 4, Insightful

    Microsoft has a habit of padding their sales results. How many of those 100 million licenses are currently in use? Does it include bulk purchases by OEMs? Does a Windows 8 license get subtracted when a user upgrades to Windows 7 or Linux?

  5. Re:This just in! on Popular Android Anti-Virus Software Fooled By Trivial Techniques · · Score: 4, Informative

    Virus 'signatures" are an ideal technology for dealing with common threats from the late 1990s.

  6. really long science fiction short story on Xkcd's Long-running "Time" Comic: Work of Art Or Nerd Sniping? · · Score: 1, Interesting
    The characters built some stuff on the beach, and now they are wandering around trying to figure out how their world works Their world does not work like our world.

    The form of story is unusual, in that one must use additional technology to follow it. Which the reading community developed very quickly. I use xkcd.aubronwood.com/.

  7. Re:The Smart Grid Has Arrived on The Smart Grid Has Arrived · · Score: 2

    Stealing power takes a certain level of knowledge and attention to detail. Quite a few power thieves manage to send themselves to the emergency room or morgue each year. This is far more common in regions where the theft rate is so high that the power companies install the brains of the meters on the pole transformers. They just put a remote display on the residence.

  8. Re:Yes but is this 10 units like MS Surface or? on Raspberry Pi Goes On Sale In US, Sells Out · · Score: 1

    There were 70 units available when I read an article about it this morning. 46 left when I started to order my 2. They probably started with more, but still much closer to 10 than 300k.

  9. Re:Slashdot - News by Morons on Raspberry Pi Goes On Sale In US, Sells Out · · Score: 4, Interesting
    I ordered two Model A's this morning. (I saw it in the Raspberry Pi news section of Google News.)

    I already have a few Model B's. I will develop on a Model B, because the ram makes a performance difference. My projects seem to either need more than 2 USB ports anyway, so the built in 2 port USB hub on the B doesn't help. I usually have an external hub. And most things I do are wireless, so the built in ethernet isn't useful. So why pay the extra 3.5 watts?

  10. Microsoft vs. Raspberry Pi on Microsoft Wants Computer Science Taught In UK Primary Schools · · Score: 5, Insightful
    Maybe Google scared Microsoft with the donation of 15,707 Raspberry Pi systems.

    Everyone knows the goal is to get users hooked as young as possible. Schools have small budgets, Adding more Raspberry Pi seats is way cheaper than adding more seats with Microsoft Windows. Microsoft may have a hard time.

  11. How to make a fool of yourself with the cops. on 58,000 Security Camera Systems Critically Vulnerable To Attackers · · Score: 1
    So there I was, trying to retrieve the video of the suspect for the cops, and it turns out that recording had been turned off on all 16 cameras 12 hours before the incident.

    No network issue here, I never connected the system to the network.

    One of the last things the system recorded, was the wee little hands of the owner's 4 year old grandson, playing with the mouse. He made all 16 little boxes in the status grid turn black. Just 16 little clicks.

  12. Stupid prior art invalidates stupid patents on Crowd Funding For Crank Physics · · Score: 1
    TFA has a link to stupid prior art.

    New bad ideas can be patented. It isn't supposed to be possible to patent old bad ideas. The problem, is that old bad ideas are often badly documented, because they are bad ideas. If the patent examiner doesn't find the prior art in the limited time available, then the examiner is likely to grant the patent.

  13. Re:RC car or "real" robot or ? on 2013 FIRST Robotics Competition Kicks Off · · Score: 1

    The first 15 seconds of each match are autonomous and the goals are worth twice as much. The remaining 2 minutes of each match are teleoperated.

  14. Limited Edition is a Euphemism on Intel To Debut Limited-Run Ivy Bridge Processor · · Score: 3, Interesting
    If they could make enough of these wonder chips to satisfy the projected demand, they wouldn't bother with a "Limited Edition". They're limiting sales to match their manufacturing capacity. They don't want to cannibalize potential Atom design wins with this chip that they can't yet make in high enough quantity. Expect the "Limited Edition" moniker and associated high price to go away "real soon now".

    Once they can make the things in sufficient quantity they will undoubtedly make versions with server features. Most server buyers don't need or want on chip graphics, but do want ECC.

  15. The causality choices aren't mutually exclusive on Using Multiple Forms of Media At Once Correlates With Depression, Anxiety · · Score: 3, Interesting

    Depressed people are also likely to self medicate with cigarettes or alcohol. And using cigarettes or alcohol sometimes leads to depression. In some people, it leads to a positive feedback loop.

  16. Re:800C? on "Self-Healing" NAND Flash Memory That Can Survive Over 100 Million Cycles · · Score: 5, Insightful

    The very, very small area is probably a few orders of magnitude smaller than your concept of very very small. The ieee article says it will take months to test 1 billion cycles. There are on the order of 10 million seconds in 4 months, which means the researcher thinks he can test at the rate of 100 cycles per second. In other words, the regions are so small, it takes on the order of 10ms to cool enough for the next test cycle.

  17. Nexus 7 boots Ubuntu or Android on Dual-Booting PengPod Tablet Can Run Linux/Android · · Score: 1

    It wasn't that long ago that we saw that someone had ported Ubuntu to the Nexus 7.

  18. Re:Combustible clothing on LG Builds Working Flexible Cable Battery · · Score: 5, Interesting
    When I worked at a lithium battery factory, we were taught to call it "out-gassing", and never to think of it as "fire". This is because a fire extinguisher would be worthless against an out-gassing battery. Just as rocket engines contain the perfect ratio of fuel to oxidizer for truly spectacular, and dangerous failures, charged batteries contain all they need to ruin your day. Smothering them in water, foam, or CO2 is not going to slow them down.

    This is why you don't see many lithium batteries in steel cases anymore. They figured that the pipe bomb configuration was a bad idea.

  19. Re:Has already powered an.... iPod Shuffle on LG Builds Working Flexible Cable Battery · · Score: 2

    The linked article shows the capacity as 1mAh per cm of length. A 20cm chunk would have 20mAh. They charge them to 4.2 volts, but I assume the nominal voltage is probably around 3.7volts. So 74milliwatt hours in 20cm.

  20. Re:My bleeding eyes... on Baserock Slab Server Pairs High-Density ARM Chips With Linux · · Score: 2

    It is less than half depth. There is a gap for hot air between the front and back units. In the pictures and animation on the Baserock site there are more ventilation slots. It appears that the air enters each through the front and both sides, and exits through the back. This will produce a chimney of heat in the center of each rack.

    It varies with local laws. Here is a link from the state of Utah: Girl, 13, charged as sex offender and victim.

  22. Parenthood rights for child rapists??? on The Mathematics of 'Legitimate Rape' and Pregnancy · · Score: 1, Offtopic

    If the mother is under the age of consent when giving birth, you can be sure she was under the age of consent at the time of conception. So we can be sure that in 100% of those cases, it was statutory rape.

  23. Re: optical images have an ultimate resolution lim on Color Printing Reaches Its Ultimate Resolution · · Score: 4, Informative

    This just hits the resolution limit for color printing that includes red. It is possible to make color images with just greens, blues and violets at a higher resolution, it just wouldn't count as full color. Researchers could go to even higher resolutions, if they just use blues and violets, but they wouldn't be able to render a very convincing human flesh tone. Competition will start shortly, for the smallest smurf vision display.

    Electrical properties of living creatures are not really known for being stable, particularly among sick people, the intended users for this device. Good thing that the summary has so little to do with the paper, because the summary is pretty silly
