  1. Ok, here goes nothing... on Recommendations for Digital Security Systems? · · Score: 5, Informative

    Assuming that you manage about a terabyte of storage, here are your numbers...

    Let's use Tivo's basic quality as an example, but drop the framerate to 15fps. This should look acceptable considering the limited changes from a stationary camera.

    A week's worth of data would use up 49 GB per camera. 16 cameras? 784GB.

    I'd advise settling for something more realistic at this point. Perhaps lowering the resolution, or going grayscale. Either way, you've still got to address *sixteen* cameras, so they'll need to be Axis webcams or something else capable of talking IP. There's no way that you'll get away with USB cameras.

    So, assuming that black and white reduces you to 33% of the previous number, that's still 262GB per week.

    You'd need slightly over two *terabytes* of storage to handle 8 weeks of 15 fps, TV resolution, B&W footage from 16 cameras.

    And you'd still need a way to encode the video feed to MPEG on the fly at the camera. And handle roughly 2.3 Mbit/sec per cam into your "server," which would have to reliably write 37 Mbit/sec to your 2 TB array. Without failing.

    Now, considering the fact that this is all *WAY* under Fast Ethernet and ATA specs, it's doable. But a homegrown solution with 8 week rollback just isn't feasible. Drop the rollback by a bit, dump to tape (unless you've got a fiber line going to a remote site for backups,) and keep a lot of spare drives around. You can't afford to have a failure anywhere in this assembly.

    Sorry if I've taken the wind out of anyone's sails through the judicious use of math, but I just wanted to make sure that no one does anything without being informed.

    Granted, it's not out just yet, but you could make it handle wireless, inbound traffic, and two internal segments fairly easily.

    The only problem is the dependence on CF. Logging isn't generally a good idea to media that can't handle excessive writes. While a Microdrive would fare better, it would also cost much more.

    Okay, now suppose that your expertise where you live gets you enough to be a member of the lower middle class in the area where you live. Let's also assume that you have incurred massive amounts of debt due to college. You owe lots of cash, can't move, and the local company is paying you enough to live from paycheck to paycheck.

    Now, someone from another country comes up and offers you a job that lets you suddenly live in a wonderful new home, cover all your debts, and still put cash away each month. Do you really see a problem with that?

    It's not exploitation to them, since there's nowhere else to go. And as soon as they've saved up the cash (2, maybe 3 years tops?), they'll be in the US demanding 3 weeks vacation, 75K/year minimum, and getting it.

  10. But do we need gravity everywhere? on Expert: Mars Astronauts Would Lose Teeth · · Score: 2

    I know that we all think that a spinning spacecraft is a wonderful idea, but it's a bit much.

    What about just a single chamber, perhaps along the lines of living quarters, that spun, much like the old amusement park rides?

    A certain amount of exposure to ~1g per day should be enough to ward off the deterioration of bone mass, and it would be cheaper than engineering an entire spaceship to spin fast enough to induce gravity.

    Of course, I'm certainly missing the key detail of this spinning chamber most likely staying in place while the rest of the ship spins, but I leave the tough work to the NASA engineers :-P

  11. SGI probably feels just fine. on Linux goes to Hollywood · · Score: 5, Interesting

    As the article says, and we should all remember, SGI's also selling Linux boxes now.

    It's easier to go with something that's being worked on by the Open Source community, since you can be pretty sure that any Open project with sufficient momentum will get the major kinks out over time. Besides, it's easier for SGI than to keep on supporting IRIX, which has had its own fair share of disaster stories.

    It's going to go back to a hardware battle, and this is where IBM may not be ready to compete. Using Linux is nice, but what about render times? What about the overall architecture? Are these IBM boxes going to beat out SGI in price and performance?

    If so, then SGI should worry. Linux has nothing to do with it.

    Gel wrist pads? You know you are not supposed to rest your wrists on anything as you type?

    I'm aware of the "rules" for ergonomics. That said, I'm not resting *as* I type. I rest my wrists on them when I *stop* typing, but I still have to read. Reducing wrist travel makes it far more comfortable to deal with using the computer, not just typing or mousing about. It's a bit of a holdover from piano lessons. If you can't keep a quarter on the back of each wrist as you type/click, then you're doing it all wrong.

    As for the questions regarding accidental gestures, the system I'm using traces my gestures, and only responds when I'm holding down a button. The result is a system that costs me my right mouse button (with an updated interface, I'm sure I could assign that to the fourth button on my logitech.), and even that can be turned off pretty quickly.

    That said, the gesture system has its flaws, and so does excessive reliance on wrist pads. You have to know what you're dealing with before you hurt yourself doing something stupid.

    I'd have to disagree with that. I've been running on a gesture system for a while now, and it's actually more convenient for most simple tasks. Since I don't have to move my hand from mouse to keyboard as often, and I have a decent setup (gel wrist pads are amazing), and I *stop* every hour or so to make sure that I don't overdo it, my wrists have been fine.
    The reduction of mouse to keyboard switches has done wonders for my overall speed with my system, and caused the small amount of pain that I was already in to go away.

  19. I'd go for Sun. Wait, I did. on 1U Apache Servers - Sun or Intel? · · Score: 2

    We've got a PowerApp.web 120 over here and a brand spanking new Netra T1 AC200.

    The AC200 is a carrier grade system, and it shows. It's (relatively) cheap, it's got a USIIe chip, and it's the most manageable box I've ever touched, even amongst other Sun gear.

    The PowerApp may still have a bad motherboard revision floating around that doesn't work with their own Redhat install.

    The most important issue to take in, however, is that upgrade cost. Sun will charge you an arm and a leg to upgrade, but you won't *need* to in most cases. These are throwaway boxes.

    The nicest part, though, is the size. The T1/X1 is about half the depth of the PowerApp. For a 2 post rack, the PowerApp is a 2 man job. For the Netra, it's 1 person, no problems. The box is just easier to hold in place while screwing it in.

    Just make sure you have the 25-pin male/female adapter for the Netra if you ever want that serial port to work.

    Of course, once they're up, the hardware's proven stable, and the apps are installed, they're about equal. I don't touch them after they're up, because they both run just fine. But I prefer the Netras based on size, price range, support, and OS. Re: Solaris vs. Linux for anything critical, I'll have to stand by the one with a more stable default filesystem, better manufacturer support, and more thorough testing. I still feel burned from the motherboard incident, regardless of how quickly it got handled. We should never have gear that is not 100% guaranteed to work with the installed OS.

    Well, first off, Mr. Ego who posted that story wasn't listening very closely. What Sony's got is the GSCube, and all it is is a cluster of the original PSX CPU and some added logic to glue them all together. And yes, it runs Linux. And yes, it's massively parallel to the point of doing Matrix effects in real time or so. Sony's publically admitted to having this piece of hardware around, since they see a massively parallel architecture as the Holy Grail of console gaming, once programmers learn how to use it well.

    Of course, if Sony is in violation of the GPL, then they deserved to be hauled into court. Not because of any supposed superiority of Free Software, but because it's a flat out license violation. GPL, BSD, or proprietary, Sony has to learn that they have to play by the rules.
