    Remember, there are two ways to get someone to buy something.
    1. You can make something they want, so that they choose to buy it
    2. You can make it legally mandatory, either by direct requirement, or by outlawing the alternatives.

    Ok, I looked at it, with their helpful red boxes to indicate what they think was taken. I could believe there might be some photoshopping in the body and head, but the background doesn't make any sense at all. I don't see more than a stylistic resemblence between the buildings in the "original" and the "ripoff". The general pose and style of armor are really close, but, like Radix itself, really just more mass-produced crap like all the other anime crap out there. I'd think having a 12-year-old's fantasy drawing on their application would have done them more harm than good.

    A fighter pilot sits fairly upright. It's a long way from the top of the head to the bottom of the feat, compared to laying down, where your head and feet are at the same level. Of course, at 11G, the blood pressure in the blood vessels at the back of your head while laying down perfectly would be about like hanging from your feet at 2G. Nevertheless, it's endurable, and greatly increases efficiency of the propulsion. You wouldn't want to perform complex tasks at even 3G, but you could easily endure it.

    It doesn't mean the velocity is faster than 'c'.
    That's how it's negative...Thank you. I'd been beating myself around on this one. Trying how to figure out how to get a negative IR. An IR less than 1 would be big news... Oh, wait. It already was.
    So when it enters the material, it is going back out of the material? Ok, I think these guys have simply discovered reflection. If, at the interface from medium A to medium B, it reverses direction, it never entered medium B. If it did enter medium B, then it is moving in the positive direction in medium B, which this article says it isn't. Either medium B is non-homogenous, and is using a gradient of IR to bend the light back out the surface, it is reflection, or they're playing silly symantic games concerning the direction of time.

    Making this shift even more lucrative for the studios is the cost of manufacturing DVD's, which at slightly more than a dollar per disc is less than half that for a cassette.

    First summer I had my license, our local Barney Fife pulled me over. I was feeling pretty safe, because I had just quietly left the parking lot, complete stop at the intersection, no tire noise, and hadn't yet reached the speed limit. I know he would have come up with something, probably the classic "broken headlight" if I'd not surpressed the reaction to burst out laughing, when he gave me a warning because I was "thinking about" speeding.
    He was right, though. He'd seen me a couple of times when I was out of reach.

    Does everything on here have to involve Linux? Besides, I doubt that Linux is going to choke on arbitrary bad sectors. Bad sectors in the boot chain or swap, sure, but unless the drive is in the process of failing, you should have them all mapped out anyway at install time, via badblocks (mke2fs -c).

  12. bus speed? on Digital Video Capture and High Frame Rates? · · Score: 4, Insightful

    At 640x240x24, you're talking 7372800 bits per frame. At 1000 frames/second, we'd need to be transferring 7Gbps. That would be a bit hard to handle. You could cut the rate by dropping colors. At B/W, it'd be pretty manageable, but that's probably not what you want. You probably also want higher resolution. No matter what, you wouldn't be able to swallow the stream for long.

    Oh, and by the way. The confusion about a million frames/second versus 103 was just poor word choice in the article. What they mean is a 1 microsecond shutter speed - 1 microsecond frames with 9707 microsecond gaps. Great stop-action to cut blurring, but manageable transfer rates.

  13. Re:Bad weather on Solar Surgery · · Score: 1

    This kind of beam would be useless for cornea modification. They use the excimer laser because it's completely absorbed in the first layer of cells, flashing them to puffy dust (it looked really wierd from the inside). Using sunlight, they'd have something more suitable for things like sealing leakers in diabetic retinopathy, for instance.
    Obviously, this tool gives doctors in remote field hospitals and in primitive areas an extremely high-precision scalpel that makes non-bleeding incisions, and should cut down sepsis substantially. Surgeries would have to be performed only on cloudless days. If you had a laser handy for backup, you'd use that instead, and wouldn't need this.

    She should have pointed out that that was only while boosting. Automobile mileage is not measured just for accelleration. Coasting is part of the trip too, and once you're out of the atmosphere, you can coast for a long, long way. Look at voyager - Not a drop of fuel used in 20some years. They're squeezing every mile out of that fuel, or how about that Saturn V second-stage from an Apollo shot that gave us all a scare a few years ago, looking like an asteroid.

    It's also a dupe. Even with my crappy memory, I wouldn't forget a story like this.
    It'd be massively stupid to build one of those in the middle of Indiana farmland, or the ocean, but we're talking about low-productivity desert, within a reasonable transmission distance from population. Besides, who knows what kind of bizarre weather disruptions it'll cause? It'd still be localized, and any probable change in the weather around there would be an improvement. It'd be funny, though, if it just built up a big thermal inversion and capped itself off.

  23. response to the question and Re:Buried fibre on Wireless Dilemma at Newton's House? · · Score: 4, Insightful
    Before I offer a useful response to the question, I must add a new acronym. RTFP (Read The Fine Post) -
    Hard line (cabled) ethernet cannot be used as it will be both be too expensive and involve digging underground which is not allowed.
    Oh. You can't bury copper, but you CAN bury fibre?
    Now, answering:
    The mention of "high gain aerials" points the way.
    Find a point in each building where rf-transparent material (glass would be best, but wood sheltered from rain would do (2.4Ghz and water, don't you know)) faces a spot of similar material on a building you want in the network. Finding a trail of thses, connecting the dots, you can then lace the campus together with 802.11 WAPs, pringle-can antennae, and some N jumper cables, and you're using 802.11 to bridge the buildings, probably for about $200US per building. Note that the antennae don't have to be at the exterior wall. Inside a nice DRY wooden cabinet, able to see the target through a window, will do nicely. Sure, the wall may block signal, but it's signal you don't care about anyway. I don't know of any WAP that can be both a bridge and an access point simultaneously, so you'd need a second wap in the building if you want to use 802.11 to the nodes. Otherwise, you just hang the bridging WAPs on the wired network.
    OOH! Do these buildings have cupolae? If so, enough rf should shoot through the slits to propogate even during mild rain (put the WAP inside a tupperware container or something).
  24. Re:Does USB Have Power to Go That Far? on DIY USB Extension Cables Using Cat5/6? · · Score: 1

    It's a timing thing. A simple amplifier can do nothing, even if it somehow caused 0 delay. It's more like the maximum length of an ethernet segment. It's timing. 3 meters at 66% the speed of light (usual speed factor of metal transmission lines) is the maximum timing drift. There's a bit of wiggle-room, to let the devices meet timing, so you might be able to stretch a single segment to 4 meters. The high-speed supposedly is good to 5 meters, also with a bit of fudge. Beyond that, the signal, with its timing, must be regenerated.
    For an analogy, think of one of those marble racetrack things, where you send the marble down lots of troughs, jumps, and such. At a certain distance, you can set up a jump that succeeds every single time, forever. Beyond that distance, you may be able to tweak one that still makes it every time when you're testing it, but change the temperature, let the joints in the tracks wear a bit under vibration, let the marble sit in the sun for a few minutes, whatever, and the ramp may fail 100% of the time. Making a custom ramp/landing box combination could let you greatly exceed the limits of the specification. As long as your combination uses the nonstandard interface to each other and the standard interface to the standard modules, there's no reason not to do it.
    With USB, though, I have never heard of anybody making a bridge. It looks like 5 3 or 5-meter segments are the best you can do.
    For my webcam, I gave up and got X11 (made sure i bought it by going directly to their URL. I'll be DAMNED if I'm going to click a pop-up/under) for the last 100 feet. Resolution sucks, though.
