  1. Re:Get with the Times Linux on Ubuntu 12.04 LTS Won't Fit On a CD · · Score: 1

    I remember back when DOS 3.3 came on three (3) high density 3.5" floppy disks...and all computers did back then was compute and all they do now is compute...

    How standards-compliant was the web browser packaged with DOS 3.3? How about the free office suite?

  2. Re:Ok on Ubuntu 12.04 LTS Won't Fit On a CD · · Score: 1

    Ok, use a DVD, now you have space for whatever Unity/Gnome3... AND Gnome 2.

    Space is not the issue with Gnome 2, support is. Ubuntu 12.04 will be supported for five years (not the usual LTS policy of three years) on the desktop. Canonical cannot guarantee that they can maintain abondonware for five years. They had the same issue with a previous Kubuntu release when KDE 3.5 was abandoned, and the Kubuntu version was not LTS as was the Ubuntu version.

  3. Re:overburn! on Ubuntu 12.04 LTS Won't Fit On a CD · · Score: 3, Informative

    Overburn is a great option, but it does _not_ work with name-brand media. Cheap CD media has a lot of overburn space because the manufacturing process is, well, cheap and the tolerances are not strict. Therefore the manufactures leave a lot of overburn space that may or may not be useful. With these you can get anywhere from 750-780 MB on a disk. The name-brand CDs are manufactured to ISO 900x specs, so they can bring the tolerances way down. You might not be able to go above 720 MB on some of these.

    Note that no matter which type of disc you overburn, the end might not be readable! I hope that something nonessential is way out there on the end, and that the installer knows how to handle a non-read potion of the end of the disc.

    Conservation of matter dictates that the pancakes are still there.

    You have never seen me eat pancakes. I gobble them down so fast that for every m of pancakes I eat, 1/c^2 of e is released.

  5. Re:It's all downhill from here on AMD To Lay Off 10% of Global Workforce · · Score: 0

    I encourage everyone to read The Lights In the Tunnel, as a primer on the coming age of technologically driven systemic unemployment.

    Or Atlas Shrugged, which describes almost this exact scenario of regulation and company-destroying in the interest of the public good.

  6. Re:how about low-tech on Light Barrier Repels Mosquitoes · · Score: 1

    Great research. But this seems to me like overkill. A mosquito net works and is proven and costs very very little.

    No, you don't understand. The researcher specifically mentions that the laser divides space into two parts, and that the mosquitoes cannot move from one part of the space to the other. Do you really think that a simple net could divide space into two parts?

    Back in to replace boiled water? Is there not a closed radiator at the top? (that was my assumption, having never worked on such a system)

    Tank you for the explanation.

  9. Re:idiots. on Belgium To Give Up Nuclear Power · · Score: 1

    I was under the impression that the isolation condenser is gravity fed: hot water goes up and away from the core and cool water flows down towards it. Of course, if the water is boiling away then that is another issue, but at least it does not require electricity.

    Please correct me if I'm wrong, I am not a nuclear engineer. Thanks.

  10. Re:Radiation Symbol on Blow-By-Blow Account of the Fukushima Accident · · Score: 1

    Just how hard is it to put a radiation symbol right side up? What a good way to destroy the credibility of your journalism by implying that you've done so little research into this that you don't even know what the symbol for radiation is, let alone what radiation and radioactivity are.

    That's all right. The Japanese flag is upside-down too!

  11. Re:idiots. on Belgium To Give Up Nuclear Power · · Score: 1

    Pretty hard with old reactors. You require something catastrophic to happen. Pretty close to impossible for new designs that use passive cooling systems.

    Fukushima had a passive cooling system. It was _shut_down_ because it was cooling too quickly!

    That will break as soon as I edit the file with a non-supported application (that doesn't know to update the stored SHA1 hash). This is why it is important to implement the feature at the filesystem level.

  13. Re:In short.. on Rethinking the Nature of Files · · Score: 1

    I have never seen a discussion like: "I downloaded a picture from facebook and now all the likes and comments are missing!"

    I have actually run into this when moving photos from BrilliantPhoto (Windows-only) to F-Spot in 2005, and then again when I moved from F-Spot to Digikam some years later. The solution lies in _embedded_ metadata fields such as IPTC or XMP. Some implementations try to use "sidecar" XML files for metadata. It does not work very well as then _all_ applications which use the file must know about the sidecar files and fully support them. In practice that never happens. Now these researchers want the applications and devices that couldn't figure out sidecar files to understand filesystem-specific metadata?

    I can operate an Evo with one hand. I also have very small hands (16.25cm from base of palm to tip of the middle finger.)

    Man this sounds like an infomercial. I won't mention any free SIP providers by name. Google them. There are several.

    Go ahead and mention them. The ones that I've dealt with are hard to set up and have terrible service. If you know better, then I'd like to be informed as well.

    Actually, that is one of the advantages of the 787:

    More efficient, more _consistent_ fuel usage. The plane weighs much less than comparable or competing aircraft as it is the only one which incorporates a plastic (composite) fuselage.

    Consider, it would take light over 4 seconds to cross from one side of the sun to the other (if it were crossing vacuum and the sun weren't in the way)... That tiny comet hitting one side couldn't possibly cause a CME to blow off the other side in less than a second.

    From the scale of the image, then either the comet was traveling at faster than C or the video was sped up. The CME occurs a slight delay after where the comet would be had the Sun not been in the way, accounting for scale and video speed.
