    No, that doesn't explain it. At 3.6MB/min one hour of footage ought to be about 13GB, without overhead, regardless of whether it's on tape or on a hard drive.

    Assuming that the guy didn't actually transcode it from DV to MJPEG, then there's no reason why it should have ballooned in size like that. AVI is just a container format, it can easily have the DV data inside of it, without re-compressing each frame to MJPEG. Unless AVI adds a huge amount of overhead to the DV data, as compared to Quicktime or some of the other container formats.

    But because MPEG-2 is interframe compression, not intraframe as is DV and MJPEG, it's not suitable for editing. Those camcorders will never be good for anyone who wants to do anything with their video except watch and archive it in raw, recorded form.

    It's a big pain to make a cut when the frame you're cutting in on depends on information located in the preceding frames. In fact, I think it ought to be impossible, without transcoding to an intermediate format and back. (And since we're dealing with lossy compression, the associated loss of quality in doing so.)

  3. Re:Macs, Analog, 2 Cameras? on Cheap Tapeless DV Capture? · · Score: 1

    While I'm not sure that carrying a Mac Mini around is exactly the solution this guy is going to be looking for, it would be possible.

    The data rate of Firewire is indeed 25 megabits per second, which turns out to be around 3.6 MB/s, well within the capability of the Mini. And he never said anything about wanting to transcode on the fly...and given that to people doing professional video, DV's quality is considered pretty minimal anyway, I'm not sure it's safe to assume that anything less would be acceptable.

    What I think he should consider is a DV camera to hard drive 'direct box,' like this one. It allows you to connect a camera's digital output directly to a portable Firewire hard drive. Since the box doesn't contain the disks itself, you can just swap the drives for each project. At $1k, they're not cheap, but neither is anything that's designed for professional video production.

  4. Re:Whats the problem? on Towards a Comprehensive USB Flash Drive Policy? · · Score: 1

    Just because a laptop is missing or stolen doesn't mean the data on it is instantly compromised. You can easily use transparent encryption for everything on the hard drive and unless it's stolen while turned on and unlocked, the data is most likely safe.

    Most people who steal computers take them for the hardware, not the data. If they can't get into the HD to take a look around in a few minutes, they're just going to reformat it and sell it on eBay.

    Also, why would encrypting the data and putting it on a thumbdrive be any more secure than encrypting it and putting it on a laptop? The thumb drive, being small and cheap, is just that much more likely to get lost. Sure, people lose laptops, but they lose small things like keys a lot more. If you want someone to be careful about something, make it big, heavy (or at least heavy enough so you can tell whether it's in your briefcase or not when you pick it up), and expensive. Not tiny, lightweight, and practically disposable.

    OT: I've always wanted a laptop with some sort of remote self-destruct feature. Something impressive but not overly destructive, like a thermite charge strapped to the motherboard and hard drive. That way if it got stolen, the next time it got connected to a network...(hiss...fizzle). No compromised data. I suppose you'd probably have a hard time getting that on a plane, though.

    I was going to say the same thing as the other respondent did; CAD stations for years have used mouse-like pointing devices called 'pucks' that have tons of buttons, and interface with particular software packages. I don't know whether they're still in wide use (they were pretty slick, I'm not sure why they wouldn't be) but back in the early 90s I saw rooms of people slaving over them.

    Some of them struck me as being particularly cool because they had a flat piece of plexiglas mounted to them, parallel to the mousing surface, which had a cross-hairs on it and could be used to precisely position the mouse on paper blueprints. The speed at which a draftsman could digitize paper plans with one of these pucks was staggering.

It's unfortunate that it wasn't kept just to the expensive ruggedized Motorola-Nextel commercial handsets. You don't see regular people walking around using business two-way radios in public, and you shouldn't use a PTT cellphone either.

  7. Only A Couple Hundred Miles...Straight Up on Another Amateur Radio Satellite · · Score: 1

    The fact that it's a couple hundred miles up is what makes it different. Sure, getting a signal from Pensacola to Key West wouldn't be a big deal today, because you can retransmit the signal via repeaters located up and down the peninsula. (Or use HF, which is a completely different technical challenge, but is pretty well understood.)

    Imagine trying to get a signal from Key West to a point equally far away, but without any repeaters or being able to use longer frequencies for the HF advantage -- that's more like what space communications are like. It's a whole new ball game.

    Furthermore, there's just something different when it comes to being in space at all. Even if there weren't the technical challenges involved, it would still be interesting to do, because it's just fascinating to be directly involved with something that's orbiting the earth. I understand that might not ring everyone's bells exactly, but for some of us it's a pretty attractive draw.

    Asking 'what's the big deal, it's only a few hundred miles' is kind of like asking someone who's going on a submarine down to the Titanic: 'what's the big deal, it's only three miles...'

    They're fair assumptions if you've been watching the progress and goals of media companies recently.

    Basically, they want complete control over any interface that outputs copyrighted content. So either you can play your audio out of an analog output, probably with some "subaudible" watermarking and/or degradation, or it goes out some sort of controlled digital interface, which will only cooperate with DRM enabled hardware.

    In order to get full resolution sound and video, under the media companies' real wet dream of a future, you'd basically need to replace everything from your computer to your home theater amplifier, with closed boxes that support DRM. I doubt people will do this though, instead they'll just have one DRM-enabled box (the computer) and watch whatever degraded analog output it produces, instead of the high-quality but impaired digital ones.

    There are a lot of things I'd pay five bucks for, including a piece of software or game that I just thought was really neat; for me to pay $20 it would have to be something that I really thought I would use regularly. At least for me, $20 puts a product out of the instant-impulse-purchase category, especially when you're buying online and not in a physical store.

    A less-severe alternative, which would just keep people from leeching bandwidth outside the coffee shop itself, would be to enable WEP and change the username and password frequently. (Yes, I know WEP can be cracked, but if you change the pass frequently and use a long key, it ought to be OK.) Then post the username and pass up on a chalkboard someplace in the shop. Customers get their wireless, and you still get to seem like the good guy -- which might be important if the shop is playing for a certain bohemian ambiance.

    Someone should mod the parent up.

    Everything he said is very true: except in rare cases, just tossing an AP up in your coffee shop isn't going to do anything good for business, assuming the shop already has an established clientele. Especially in an urban area, where people can just sit on the street outside the door and get access, or across the street using a directional antenna, you might not get a single new customer from it.

    However, if you are just starting up a business and trying to draw new customers, and especially if you're in an area that's not teeming with people, free Wifi might be a cheap way to attract and establish a customer base. You can always switch to a system that requires a receipt-printed code or something later, if the place starts to resemble an Internet addict's opium den. But if you're just getting started, there's not a whole lot to lose in trying: the investment is fairly minimal, and you might get some good customers out of it, depending on the demographics of the area.

    A few years ago when I was in Budapest, I saw that a lot of the fast-food joints had internet kiosks that you could use for free ... after you'd bought food. On your receipt was a code that you had to type in, to get access.

    It wasn't unlimited, either. I think it was 30 minutes for each meal purchased. Which seemed to me to be pretty fair -- especially when you're talking physical kiosks instead of Wifi, a time limit keeps people moving.

    In that vein, wouldn't it be possible to write some code that uses the MAC-type address of each Wifi client to limit the amount of time it can connect for? Say an hour a day or something?

    Or maybe something more complex, where you get an hour free, but then can extend for another 30 minutes with each purchase. Thus you can sit there as long as you want, as long as you're buying a cup of coffee every 30 minutes. (For those who don't want the coffee, maybe you could just pay a fee -- 75% of a cup of coffee, perhaps -- for internet alone.)

    Yeah, it's not as if they have a massive database somewhere of every printer in the country (at least, I hope they don't). I think the idea is more so that they can tell if two documents were printed on the same device.

    E.g. it might let them tell an 'authentic' ransom note from a copycat, because it wouldn't be on the same printer. Or at least it would give positive verification that two notes were printed on the same machine, rather. I guess having them printed on different machines doesn't really compromise the validity by itself.

    Frankly it seems a little like a solution looking for a problem. Someone in the government saw an opportunity to make something anonymous less so, and took it.

    Relatedly, I remember reading somewhere a long time ago, about a forensic technique used to identify a specific laser printer from printouts, which used unique patterns produced by small defects and dirt on the drum. It might have been a copy machine, now that I think about it though. Anyway, my point is that even without the microdots, the authorities still have ways of potentially linking printouts to a particular machine: the thing I don't like about the microdots is the per-machine serialization. It makes it too easy to go from there to full 'Printer Registration' where you have to link the printer to a person.

    I think you hit the nail on the head.

    What makes people buy Apple is not their software. It's not their hardware (with the exception of the iPod, perhaps). It's certainly not their price or perceived value.

    What Apple survives on is two things: 1) the semi-mythical and nearly impossible to quantify 'coolness' factor, and 2) the user experience. People buy Macs because they're easy to use (or at least they have a wide perception as being easy to use, which in marketing is virtually the same thing) and powerful. It's the whole "it just works" philosophy, as cliched as that might sound.

    Apple can maintain it's edge in user experience because they have very tight hardware/software integration. By monopolizing the hardware which their OS will run on, they can limit the number of possible system configurations and then test the hell out of them, build drivers into the OS, etc. A lot of Mac users don't even know what a device driver is! (I'm pretty sure actually if I asked for a device driver to some friends of mine they'd ask whether I wanted the flat kind or the Philips-head kind.)

    If Apple sold the Mac OS for distribution on commodity x86 hardware, suddenly a lot of their advantage would disappear. You'd instantly go from a few dozen out-of-the-box configurations to thousands or millions, and have loads of incompatible hardware that people would expect to be able to use.

    Also, they'd have to start playing hardball about software licensing, which they've never done and would probably alienate a lot of users, and do a lot of damage to their "nice guy" image. A lot of PC users are surprised to know that there is no serialization during the Mac OS install process. None at all. If you have an Apple computer and an install CD, you can put the system on it. There's obviously quite a bit of piracy that goes on (and always has) but I assume Apple just doesn't bother because they realize even the pirates have paid them some money for the hardware they're installing the stolen system on. And the progress of operating systems requires you to buy new hardware periodically anyway, so you're always going to cough up every few years. They can afford to be nice.

    If Apple started selling the software by itself, I have no doubt (given their performance with iTMS) that they would come out with some pretty robust 'activation' scheme. This to me would be obnoxious: it's one of the things I've always enjoyed feeling above, as a Mac and Free Software user.

    Apple had their experiment with commodity hardware back in the clone days (anyone remember CHRP?), and Jobs pulled the plug. I don't think they'll go back there again. The question which interests me most today is, when Apple releases their first x86 version of Mac OS X for actual Apple/Intel boxes, how hard will they try to keep hackers from moving it to commodity hardware just for hobby and experimental purposes.
