    I do. It keeps my kid (and therefore my wife) happy with Blues Clues :)

    It's $10/month, where the Tivo is $13/month, and you don't have to buy it. It doesn't have all the Tivo functionality, and at least here there are some minor technical glitches, but it's ok.

    Does the "DVR" give out a macrovision-esque signal that would keep me from archiving the shows I want to keep a tape of?
    I don't know -- never thought of it.

    I tend to doubt it though -- the standard cable box doesn't, does it? (not yet, anyways. Sounds like it's only a matter of time ...)

  2. My cable company rents me a PVR for $10/month ... on Cable Companies Despise PVRs · · Score: 2
    I have two PVRs. One was provided by my cable company.

    (It's a Scientific Atlanta Explorer 8000 I think.)

    I much prefer my Tivo, but the cable box/PVR is nice too (mostly because it's the cable box as well, and can record two things at once. And it has an 80GB drive, larger than the 20GB my Tivo came with (it has 60GB now.))

    Still, I'm planning on switching to DTV soon -- I want two of the Tivos that go with DTV (they're sweet -- they record the mpeg stream directly, so the quality is exactly the same. And of course they can record two things at once, which the SAE 8000 can, but my Tivo cannot.) Anybody know of a good DTV deal that includes two or three DTV Tivos at a good price if I sign up for a year or so?

    Again, I'm thinking single-engine planes might not be a real comfortable place to be in that situation either....
    Correct, but actually the odds of it (loss of an engine) turning into a fatal accident are higher for a twin-engine plane than for a single-engine plane. Here's a reference for you.

    In a single engine plane, you're landing, one way or another, and if you're smart, you just land straight ahead, trees or not. That rarely kills you, but it does mess up the plane. (Turning around is often fatal unless you have a lot of speed or altitude.)

    In a twin-engine plane, you apply full power to the other engine (during takeoff, it may already be at full power.) This creates a large yaw force that tends to cause the plane to roll, sometimes so much that it can't maintain altitude and it becomes a lawn dart. It can all happen very quickly, and you're probably not very high up, so you don't have much time to correct for it.

  7. Re:Disabled airplane ... on First Emergency Use of Whole-Aircraft Parachute · · Score: 2
    The pilot was taking off when the airplane became "disabled". Therefore no altitude to trade for airspeed = instant stall.
    Planes don't just stop in mid-air. Even if the engine stopped during takeoff, you've still got all the momentum you've built up until then. As long as you immediately put your nose down and kept your airspeed above the stall speed, you could land the plane (assuming there's something to land on ahead of you. And yes, trees are usually softer than the ground.)

    They do teach this stuff when you become a pilot. In fact, they go over it pretty carefully. Problems happen when people try and turn around and land back on the runway (and don't have enough speed/altitude to do it.) Or when they don't put the nose down and then stall.

    You'll need a certain amount of time to deploy the parachute too -- if you stall your plane at 50 feet, it's probably not going to save you.

    If you are near VNE you don't need the parachute.
    Of course not. Unless you just folded your wing by trying to pull a too high-G turn :)

    I was talking about it accidently deploying at the time.

    In any event, sounds like a neat device.

    Without the aileron, the plane was mostly uncontrollable
    If the aileron totally fell off the plane, I'd expect it to still be controllable (with a little work). But it sounds like (`partially detached') instead it sort of fell half way out and then hung there -- and if it jammed up or down, that could certainly screw you up -- you may start doing rolls and not be able to stop.

    Glad to hear it didn't turn out bad. That would likely be a fatal crash.

  9. Disabled airplane ... on First Emergency Use of Whole-Aircraft Parachute · · Score: 2
    Disabled how?

    If you lose your engine in a single engine plane, and you have somewhere reasonably flat to land, you're probably better of just making a normal (emergency, dead-stick) landing.

    Even helicopters don't just `fall out of the sky' when the engine shuts off :)

    Let's hope these things never deploy accidently. It would get really interesting really fast if one accidently deployed close to the ground (right after takeoff, or before a landing, for example), or while your plane was cruising at 180 mph ...

    Perhaps that's only in Germany or Europe?

    Perhaps that's only Audio CD-Rs?

    Yes, there are Audio CD-Rs and Data CD-Rs. Audio ones cost a lot more, because they have a bit set that lets them work in non-computer burners. (also, part of their cost goes to the recording industry, part of the DAT TAX.) (Yes, I'm being US-Specific here.)

    Every time I see somebody buying Audio CD-Rs, I ask them if they're going to burn them with a computer or a stereo component. They always say computer, and then I tell them to go buy the cheaper data CD-Rs, because they'll work too. And they usually thank me :)

    In any event, assuming that every blank CD created is used to pirate their music is incredibly incorrect. 1) in the US, we can make copies of music that we have purchased, for our own use 2) people do record computer files on these as well and 3) people also record music that they've made on them.

    For the classroom that was using Knoppix, the best bet is probably to have the students mount a NFS or SMB share, and put their programs there. Either that, ftp them to a file server, or upload them with a browser.

    NFS isn't ideal, because every student has the same UID, and therefore could read what other students turned in. The best bet is probably to make a web page that requests your name and lets you upload (turn in) your program, and just hit it with Mozilla (already on Knoppix.)

    Knoppix (and later Redhat distributions, for that matter, don't know about other distributions) create a RAM disk equal to one half the size of your RAM. For Redhat, it's not used unless you explicitly use it (and the memory isn't actually used unless you put something on the RAM disk) but for Knoppix your /tmp and /etc directories are put into this RAM disk. So you have space for temporary files (plenty of space, if you have a decent amount of RAM.)
    And what does the grader do when he or she receives a disk that has bad sectors on it? Floppies tend to develop them rather quickly.
    Floppies suck. This is always a problem, not restricted to this one circumstance. Hopefully the students know to make more than one copy ...

    sendmail used to send them out, but there were security issues with that, and so it's been disabled by default. For many years now, it appears. But there was a time that they were sent out as soon as your message was received by the destination sendmail.
