  1. Re:Bogus algorithm on The World of YouTube Bubble Sort Algorithm Dancing · · Score: 3, Insightful

    I agree on Bubb..I mean, BS. But Selection Sort is really only useful with big objects that you don't want to move much. These days everything's a Reference, so it doesn't matter so much. It makes for a really boring dance, too.

    Insertion Sort is more useful in modern use cases. If something's "almost sorted" it's very quick.

    Shell sort might be even better. It's practically identical to Insertion Sort except only subsets of dancers would step out at one time. And, with a good gap sequence, it gets done much quicker than either of the above.

  2. Re:Does this mean on Massive Volcanic Eruptions Accompanied Dinosaur Extinction · · Score: 1

    Well, it is thought we've found all the dinosaur-killer-size asteroids, and that none are going to impact Earth soon. But there are still plenty of smaller ones that could take out a major city if they hit in the wrong spot. The shock wave from the Chelyabinsk meteor caused injuries, though mainly from broken glass. Plus, you never know where a comet's going to appear.

    ...if nothing at the XKCD store appeals to you, that is...

    Stick one of these in a box. Label the box "Office chair". Stand back and watch the fun.

    And for those less familiar with XKCD, print out a card with that comic to go with the box. It might still work.

  5. I wish more websites were designed for wide screen on The Case For Flipping Your Monitor From Landscape to Portrait · · Score: 1

    Lots of websites limit their width to, say, 1024 pixels. Other websites, like this one, extend across the entire page, but don't wrap text which makes them hard to read.

    I wish more websites would allow their contents to wrap into two or more columns, like magazines do. Here, for instance, is a user style to wrap Slashdot comments into two columns.

  6. Re:Itr should not be an issue on Sony Employees Receive Email Threat From Hackers: 'Your Family Will Be In Danger · · Score: 1

    The problem is that the SSN wasn't designed to be an identification number. Some cards even say "Not for identification." Example

  7. Re:Blocking Tor solves nothing on US Treasury Dept: Banks Should Block Tor Nodes · · Score: 1

    OK, then, don't block everything from TOR nodes. Better to go phishing for criminals. They should allow logins to be attempted, but then block the login from occurring (regardless of whether the password was valid). They should then alert users to login attempts from TOR, and potentially freeze their access until their passwords can be reset.

  8. Slashdotted already?! on Riecoin Breaks World Record For Largest Prime Sextuplet, Twice · · Score: 2

    For a network with such "massive distributed computing power", that's some pathetic servers they've got there.

  9. Re:Will this go the same way as the spintronics? on Molecular Clusters That Can Retain Charge Could Revolutionize Computer Memory · · Score: 4, Interesting

    Spintronics is a quantum thing - a way of specifying more information in each electron. As such, it's very difficult to work with.

    This is more similar to carbon nanotubes. They're a new thing, which could be very useful, if only you could cheaply and efficiently manufacture them and put them in the proper places on a chip. However:

    "One major benefit of the POMs we've created is that it's possible to fabricate them with devices which are already widely used in industry, so they can be adopted as new forms of flash memory without requiring production lines to be expensively overhauled," Lee Cronin, a chemist involved in the research, said in a University of Glasgow release.

    So using these may be more realistic than carbon nanotubes!

  10. Re:RTG on After Four Days, Philae Team Gets to Rest · · Score: 3, Insightful

    It took ten years to get the Rosetta mission to the comet. By then a RTG would be fairly depleted too.

    Mod parent up. I got a USB drive as a gift that claimed to be 256GB! I tested it, and I think it's actually a 4GB drive with a little over-provisioning.

  15. Re:To compete in price on What It Took For SpaceX To Become a Serious Space Company · · Score: 2

    No, to compete in price against anyone you only need assets. That can be money, or it can be tangible assets, such as rocket parts that remain in serviceable condition after a launch. Probably no one here will like it, but under current law, even "intellectual property" counts as an asset.

  16. Re:He'll Never.. on What It Took For SpaceX To Become a Serious Space Company · · Score: 1

    I'm sure the solar panels from defunct rovers could provide at least a trickle charge.

    And he can put a better charging station there later.

    And then all the companies will rename their consumer plans, at the very least, "web" or "data" like the mobile companies do. And practically nobody will notice or care.

  18. Re:Gotta be a downside somewhere on Z Machine Makes Progress Toward Nuclear Fusion · · Score: 4, Insightful

    Yes, and all the stars in the sky would have collapsed, and we would have created black holes at H-bomb test sites.

    There might be nuclear waste to worry about given stray neutrons, but gravitons aren't something I'm worried about.

  19. I don't think he means war for 30 years on Former Department of Defense Chief Expects "30 Year War" · · Score: 5, Insightful

    I think he's referring to the Thirty Years' War.

    The Thirty Years' War was a series of wars in Central Europe between 1618–1648. It was one of the most destructive conflicts in European history, and one of the longest...it gradually developed into a more general conflict involving most of the great powers of Europe....

  20. Re:Sharing channel == worse picture quality on L.A. TV Stations Free Up Some Spectrum For Wireless Broadband · · Score: 1

    I don't have cable or satellite, but I heard their picture quality is way worse than broadcast usually has been. This could just be evening the score.

  21. Digital would be less "twitchy", but... on L.A. TV Stations Free Up Some Spectrum For Wireless Broadband · · Score: 1

    Digital becoming twitchy isn't just because of transitioning to digital. It's also because they lowered the transmitter power.

    The maximum power for DTV broadcast classes is also substantially lower; one-fifth of the legal limits for the former full-power analog services. This is because there are only eight different states in which an 8VSB signal can be in at any one moment; thus, like all digital transmissions, very little signal is required at the receiver in order to decode it.

    So if you were watching an analog signal of the same power, you'd have a hard time making it out too.

  23. Wireless charging on To Really Cut Emissions, We Need Electric Buses, Not Just Electric Cars · · Score: 1

    This has to be one of the best use cases I've seen for wireless charging stations. Put one at every bus stop where it's practical. Just by sitting there, while letting people on and off or just waiting to get back on schedule, the bus can be recharging. Also, buses are long, so the density of power sent through the charging coils doesn't have to be as high as with a car.

  24. Re:Maybe we need an HTML tag for image/work copyri on Microsoft Takes Down Slideshow-Building Tool After Getty Images Lawsuit · · Score: 2

    Not an HTML tag. It needs to be some kind of metadata embedded in the image itself. There are places in various formats for these things; I guess we just need better tools to read and write them.

  25. Make a key component removable and portable on Could Tech Have Stopped ISIS From Using Our Own Heavy Weapons Against Us? · · Score: 1

    For instance with tanks, if you make them drive-by-wire and you make the computer control system small enough, you can just pull the computer when you're done with the tank and take it with you.

    Of course, the enemy could counter this in several ways. They could jerry-rig the tank to work minimally without a control system, but it would not be nearly as effective. They could steal the control computer, but that's a security issue - the key components should be under lock and key and heavy guard. Or they could steal the control software and load it on a smartphone or something, but that's again a security issue. And all of these require more technical knowledge than hot-wiring a car.
