  1. Re:Never going to happen. on DARPA Begins Work On 100Gbps Wireless Tech With 120-mile Range · · Score: 2

    2. It'll need to be such high (analog) bandwidth, it'll not comply with any spectrum or power regulations, anywhere

    There may be a twisted solution to the spectrum problem, at least.

  2. Re:What about non-factory jobs?? on Automation Is Making Unions Irrelevant · · Score: 1

    The whole premise of the article seems to assume that unions are exclusively about 1950s-like factory jobs. How about all those low paying service jobs out there? I don't see too many robots stocking shelves at Walmart.

    Have you seen any? Where there's one there's bound to be more, and where there are none there's likely to be one soon.

    Actually, I'm kind of surprised by the service jobs that remain. I'm surprised we haven't seen a fully-automated fast food restaurant yet, for instance. I guess they're hiding in Japan and Germany for now.

  3. Re:Wait, what? on NCTC Gets Vast Powers To Spy On U.S. Citizens · · Score: 1

    The government should need a warrant or due process to access its own records?

    I agree. This sounds like what the government was supposed to be doing to prevent 9/11, as described after 9/11: sharing information between agencies. I thought this was the entire purpose of setting up DHS in the first place.

  4. Picture password? on IE Flaw Lets Sites Track Your Mouse Cursor, Even When You Aren't Browsing · · Score: 1

    I haven't even touched a computer with Windows 8, so forgive my ignorance, but could this be used to capture someone's picture password strokes?

  5. Re:If Nasa is about Science, lose the men altogeth on Apollo Veteran: Skip Asteroid, Go To the Moon · · Score: 1

    In fact, why are we sending a clone of Curiosity to Mars, when we could send it to the Moon instead? About all that would be required is an extra retro rocket (to replace the parachute, not the skycrane), and preferably some different instruments. (Atmosphere samplers not required.)

  6. Re:Get rid of the liquid cooling on Ask Slashdot: Geekiest Way To Cook a Turkey? · · Score: 1

    Stick it on your heatsinks and start cracking your favorite SSL cert.

    For an extra geekness point - try Bitcoin mining or AGW modelling.

    I wrote my own prime number sieves for PrimeGrid just so I could cook my turkey on my heat sinks. :P

  7. Re:"Earth"-shaking? on What "Earth-Shaking" Discovery Has Curiosity Made on Mars? · · Score: 1

    Maybe they discovered that soil at that location matches a meteorite that made a large crater on Earth? I can't think of any other way a discovery on Mars could be literally Earth-shaking.

  8. Re:Have cygwin on Ask Slashdot: What Video Games Keep You From Using Linux? · · Score: 1

    Cygwin has the advantage of more complete integration with Windows. It has the disadvantage that it's not actually binary-compatible with Linux binaries, or libraries.

    I'm running 100% Linux on my main computer right now. But for my next upgrade in 6 months or so, I'm planning to:

    1. Install Windows as the primary OS, fiddling with it however much I need to to avoid Metro.
    2. Install a Linux VM with VirtualBox. Have it run with a GUI, but in the background. Import/mount the Windows drives in /cygwin.
    3. Install Cygwin on Windows and start an X server.

    I'm hoping that this will allow me to run real Linux programs as seamlessly as if they were running in Cygwin.

  9. Re:FindImageDupes on Ask Slashdot: How To Catch Photoshop Plagiarism? · · Score: 1

    I agree that the student work should have a high visual similarity. That's why I suggest not taking its suggestions at face value every time. I think that plagiarized work should in general have a higher visual similarity than the student work in most cases. This is just a rough way to filter out work that isn't likely to have been plagiarized.

  10. FindImageDupes on Ask Slashdot: How To Catch Photoshop Plagiarism? · · Score: 5, Informative

    From the manpage:

    findimagedupes compares a list of files for visual similarity.

    To calculate an image fingerprint:

              1) Read image.
              2) Resample to 160x160 to standardize size.
              3) Grayscale by reducing saturation.
              4) Blur a lot to get rid of noise.
              5) Normalize to spread out intensity as much as possible.
              6) Equalize to make image as contrasty as possible.
              7) Resample again down to 16x16.
              8) Reduce to 1bpp.
              9) The fingerprint is this raw image data.

    To compare two images for similarity:

              1) Take fingerprint pairs and xor them.
              2) Compute the percentage of 1 bits in the result.
              3) If percentage exceeds threshold, declare files to be similar.

    Of course, you shouldn't take its suggestions at face value every time, but it should help narrow your search for cheats.

  11. I like PIE on Flexible Circuits By the Slice · · Score: 1

    Proton-Induced Exfoliation, that is. They both seem to create flexible silicon wafers of a similar thickness. I wonder whether that process would work for already-created circuits, and whether it would be more reliable. I also wonder whether this process is cheaper.

  12. Re:Batteries. on Ask Slashdot: What Stands In the Way of a Truly Solar-Powered Airliner? · · Score: 2

    Actually, assuming you leave the solar panels on the ground, batteries may be a viable option:

    1. Volta Volare has designed a small electric-hybrid airplane that should be able to go 200 miles on a charge. Of course, it's not an airliner, but...
    2. Boeing has designed a concept airliner called the Sugar Volt (video) that can cruise on battery power alone. It could be built as early as 2035.
  13. Re:Now, with centralized user tracking! on Zimmermann's Silent Circle Now Live · · Score: 1

    If there are backdoors? Doesn't the government mandate them?

    Depends on the government, I think. From one of TFAs:

    Canada's privacy laws are the most stringent in the world

    Not that I really trust the company's proprietary software any more because of this.

    In fact, the staff can be infrastructure! Seriously, I can't think of a better use for a Baxter robot than in a busy machine shop.

  15. Re:Old School: Mandrake! on Ask Slashdot: What Distros Have You Used, In What Order? · · Score: 1

    I actually bought some Linux CDs once. They were called "Linux for Windows". They were actually pretty much standard Mandrake though.

    Actually, if you include all POSIX OSes, I went...

    BSD/OS (startx to start X; xexit to "sitzung beenden") -> Mandrake -> Red Hat -> Cygwin -> Ubuntu 9.04 -> Linux Mint Debian Edition XFCE.

    I didn't really enjoy using any Linux outside Windows until Ubuntu. Then they went nuts with Unity.

  16. Re:So? on How Internet Data Centers Waste Power · · Score: 3, Interesting

    The Earth receives 170PW of energy from the sun. The sun's total output is 380YW (trillion trillion Watts). How much of that we can capture and use is limited mainly by how much money we spend. So I would say that measuring energy with money makes perfect sense.

  17. Re:How to decide the fate of helium on Scientists Speak Out Against Wasting Helium In Balloons · · Score: 4, Interesting

    Exactly! Use liquid hydrogen to cool the large magnets inside MRI scanners.

    Liquid hydrogen boils at 20.28 K. MgB2 superconducts at 39 K. (So neon would also work, but it has problems similar to helium.)

  20. Space elevator orbiting the moon? on LiftPort Wants To Build Space Elevator On the Moon By 2020 · · Score: 1, Informative

    First post? Anyway, you can't "anchor" a space elevator to the moon from lunar orbit. It would have to stretch all the way to the Earth - or at least to a Lagrange point.

    Looking through a few other Youtube videos of Morpheus tests, I found this video entitled " This is why we test". It looks very similar, except the tether kept it from flipping completely over and crashing.

  24. It's not TOO LATE; it's never TOO LATE on Is There Still a Ray of Hope On Climate Change? · · Score: 2

    Given enough clean energy, we can always build a plant that will take CO2 from the air, combine it with hydrogen from water, and make hydrocarbons. We can then gasify the hydrocarbons to produce carbon. And pure carbon (as opposed to CO2) we can sequester easily.

    Don't believe me? Look out your window. See that plant? No, the living one. That's such a plant. Then the gasification produces charcoal. Or, if you can't get enough of those plants, for this function, they can be replaced.
