  1. Command line access on Encrypting a User's Home Directory Under Mac OS X · · Score: 1
    I've never been able to mount an encrypted disc image from the command line unless I'm logged into the UI (i.e. logged into OS X normally).


    For example if I ssh into my home machine I get an error:


    hdid -passphrase "mysecret" somediscimage.dmg

    hdid: mounting somediscimage.dmg" failed: no mountable file systems.


    This disc image works just fine if I do the same exact thing while logged in locally.

  2. Lifeboat? Why? on NASA Considers Abandoning ISS · · Score: 1

    Seriously, why not just send a shuttle up, drop off a full crew (6 or 7), then go pick them up in four (or six) months. Russia would still have to send up Progress supply ships, but they're cheaper than Soyuzes. You would probably also need to leave one of the Italian cargo modules up there, both for extra supplies and for extra living space, since the US also cancelled the large habitation module.


    I can already hear (read) the indignant replies: "What happens if there's an emergency?!?!?!" Well, first the brave astronauts try to fix the problem, then, maybe, they die. Yes that would be terrible, and I'd hate to be the NASA official who had to tell their families the bad news: "I'm deeply sorry Ma'm or Sir, but due to shortsighted budget cuts from Congress and the President we were unable to provide your loved one with an emergency escape vehicle", but I personally would be willing to take that risk.


    Just in case any NASA officials are reading this, I just need to dig up my meager flight log and tweak the essays a bit and I'll finish resubmitting my application. The previous app is ten years out of date so please ignore it :)

  3. Altitude Record on Unmanned Aerial Telecom Relays · · Score: 1
    On one of the pages linked to by the linked to article, I found this:

    On August 13, 2001 on its second high altitude flight, Helios flew to 96,863 feet, shattering the world altitude record for both propeller and jet-powered aircraft (the SR-71 spy plane was the previous record holder, having flown to 85,068 feet in July 1976).
    I had no idea the SR-71 had been (publicly) dethroned! And by a propeller driven plane, at that.
  4. Re:Use Disk Copy and stay neat on Encrypting File System Options for Mac OS X? · · Score: 1
    if you type hdiutil mount imagefile.dmg on an encrypted image you get a prompt to enter the passphrase
    I wish I knew what I was doing wrong, but I've never been able to get that to work. I always get errors like the following:

    /usr/bin/hdid: "Misc.dmg" does not appear to be a disk image: No such file or directory

    hdiutil: mount: mount failed (57344).
    hdiutil: mount failed - unknown error (57344)

    But I've mounted the disk images numerous times from the finder.

  5. Re:electric circuts? on Warwick Gets a Few More Wires · · Score: 1
    on a second thought; do you have "upstream" nerve channels (hand to brain), and "downstream" (brain to foot) nerve channels? or do they just use the same neural pathways?

    Yes. Neurons, in general only carry signals in one direction and I think that holds true for the large bundles of neurons that are usually called 'nerves'. At the very least I seem to remember that that is true for the peripheral nervous system, I would guess things are more complex in the brain.

  8. Re:Article mentions Bandwidth issues on Peer-to-Peer for Academia · · Score: 1
    Actually, our brains/nervous system do have 'bandwidth' issues - which is why the doctor does that little 'smack you on the knee with a tiny hammer' test. It's like pinging your brain for a response, and how long does it take for your brain to respond appropriately.

    Sorry, but that's not how reflexes work. 'Reflexes' do not involve the brain at all. The signal from the hammer-hit goes to your spinal cord then immediately gets re-routed back to your muscles (in addition to continuing on to your brain).

    How do you (safely) extract the real file from the virus-wrapped file? I don't have any Window's machines so it would need to be a *nix or Macintoh solution.


    I doubt there is anything interesting in the dozen or so files I've received, but I always wondered.

  10. Re:Hopefully it's not all straight from the script on Lord of the Rings Theatrical Trailer · · Score: 1
    Here's the best analogy i can come up with


    I build a bird house on the far side of my property (birdhouse=Arda). I want to watch the birds so I install a camera in the birdhouse. At some point a fox breaks in and starts eating the birds or eggs. I have a gun and could easily shoot the fox, except that, even though I am watching it I'm not actually there, so would have to run out to the birdhouse before I could do anything.


    The more I think about this analogy, the less I like it, so I'll try to put it more plainly. My beleif was that Illuvatar was IN Arda only in a very limited fashion. His purpose there was to experience the world as living beings would rather than from the outside. Somewhat like the way Gandalf, Saruman and the other wizards are Maiar sent to oppose Sauron, but are not allowed to use their full power. I'm not saying that Illuvatar couldn't do what he wanted, just that he chose not to when he became Bombadil.

  11. Re:Mac OS X Support? on VIM 6.0 is Out · · Score: 2, Informative
    The screenshot you referenced clearly shows vim running in Terminal (i.e command line).


    However, it is possible to run gvim under X-Windows, which if you get a recent version of XDarwin, means it will be running in the Aqua layer right alongside your Mac programs. Try searching for XDarwin or XonX at versiontracker.com. It's not necessarily easy to get XFree86 and XDarwin running, but it's not really all that hard, either


    I've been using VIM 5.7 for quite a while under an older version of XDarwin. I haven't upgraded because it's stable and I like to use it in non-aqua mode so that I have multiple desktops.

  12. Re:Hopefully it's not all straight from the script on Lord of the Rings Theatrical Trailer · · Score: 1
    Bombadil's elvish name, Iarwain Ben-Adar, translates roughly to the oldest without father, because he was in Middle Earth before the elves came the first time. Some even think Bombadil is one of the Maiar or even the Valar.

    Personally, I think he might be a Vala, because the other mighty Maiar in Middle Earth were affected by the ring, while Bombadil was not.


    None of my friends are really huge Tolkein fans, so I guess this is just my own delusion, but the second time I read the FOTR (after I had read the Silmarillion) I was suddenly sure that Bombadil was Eru/Illuvatar himself.


    I mean, if I went to all the trouble to create this complex world, I'd want to be there to observe it (without directly changing things. Mostly :).


    To bring this back on topic a bit more, even though Bombadil is a great character, the whole Old Forest/Bombadil story is so neatly self-contained and can be separated from the rest of the story so easily, that I can easily understand why they would cut it.

  13. Re:Here is the Windows XP EULA for review : on MS FrontPage Restricts Free Speech II (It's True!) · · Score: 2, Interesting
    ...you may not use the Product

    executable software residing on the Workstation Computer,.. .

    Doesn't this mean that you can't connect a monitor to a machine running XP and then use it to display any executable except Windows XP?

    Yes, this is taken out of context, but I didn't see anything else that would refute this interpretation.

    P.S. I'm assuming that this is the real EULA and not just a joke. But I could be wrong (it's happened before)

  15. Re:STIQUITO - Build your own robot! on Fujitsu Releases Specs For Hackable Robot · · Score: 1

    As much as I enjoyed building it, the main problem with the Stiquito is that it doesn't come with a processor/controller of any kind and finding one small enough to fit the body was more than I could handle. (I'm a software person not a hardware person)

    By the way, when I bought my book there was only one on the market, so I don't know how the've improved over the past couple of years.

  16. Crewing siege engines on Fling-A-Keg · · Score: 1

    For the past six years or so I've helped crew a freind's trebuchet. For me, one of the best parts about it has been watching it evolve over the years.

    First it was traction powered (people pull on ropes), then it was widened so we could get more people pulling, then it was modified to have a counterweight (4 5gallon jerry cans full of water, approx 175 pounds). Then it had to be remade narrow so we would stop bending the weight bar pivot. Then all the side supports were moved inside making it easier to handle as well as making the length of the pivot even shorter. Then a pully system was added to make cranking the arm down easier. Hopefully next year we will have an easier way to get the pully hook up to the arm.

    Flinging stuff with a Treb is even more fun when someone one the other side is flinging stuff back at you! No, we don't throw pumpkins. We ususally use four tennis balls taped together or volleyballs.

    Pictures of the engine can be seen here. All of the links with 'War Pup' in the name are the treb. Sorry I can't seem to find any pictures of the more recent versions.

  18. Anecdotal evidence on Uplifting Dolphins · · Score: 1
    As part of a graduate level class in scientific visualization (we were using an MRI scan of a beluga whale head to try to find out which organ actually produced the sonar) I got to 'meet' one of the US Navy's beluga whales.

    The trainer made a hand motion and the whale came partially out of the water onto a dock so we could pet it. As the whale did so the trainer blew a whistle and said that was used as a reward. A couple of times the whale slid off the dock and was motioned back up by the trainer, but this time the whale gave a whistle that sounded identical to the trainer's (at least to my sonically-naive ears). When asked, the trainer said that the whale knew she was being good and was rewarding herself.

    While it doesn't have anything to do with language, it does seem to me that it is a behavior that implies a lot more self-awareness than most of the things animals are taught to do.

  19. Nanotech background on Creating Nanotech Of The Nearly-Now · · Score: 2

    If you want to get more background info on nanotechnology check out the Foresight Institute (http://www.foresight.org) or find one of K. Eric Drexler's books:
    Engines of Creation: The Coming Era in Nanotechnology
    Nanosystems: Molecular Machinery, Manufacturing, and Computation

    The former is cheaper and less technical than the second one (which I still haven't gotten around to buying).

    Certainly looks like the direct route to nanotech is going to reach a usefull state before the biologically based bootstrapping that I was always more interested in. Myosin motors and DNA/RNA computers, Oh My!
