  1. Re:GPL'ing Solaris to gain the Linux kernel & on Sun Mulling GPL for Solaris · · Score: 1

    Actually, and more interestingly, is the possibility of going the Apple route and open-sourcing the software to sell the hardware (yeah, yeah, that isn't quite what Apple is doing, blah blah blahbity blah).

    Sun makes good hardware. SPARC gear is generally very well-regarded. If they GPL Solaris so that they can suck in GPLed improvements from Linux and the *BSDs (not that they couldn't do that before), they've just drastically improved the performance of an OS that already did quite nicely on their own hardware. If this helps them sell hardware, Sun has to consider that a good thing.

    This all assumes Sun wants to stay a hardware company (which recent signs - cancellation of US5, specifically - indicate to be less likely). If they want to go software, I have no idea why they would do this.

    I feel the same way about GPLed codecs as I do about patented codecs; they're both ridiculous restrictions to apply to mathematics.

    Yes.

    But TV is filmed at 30 fps (technically, most TV is actually broadcast at 60 1/2frames (fields) per second, yielding 30 full frames per second, which is the higher figure, and therefore requires more bandwidth. Which is why I used it.

    Presumably 24 or 32 bits per pixel, like most video. (8 bits per channel color, 8 bits transparency (optional and normally unused)).

    So:

    1920x1080 = 2073600 pixels per frame * 24 bits/pixel = 49766400 bits per frame * 30 frames per second =

    177.98 megabytes per second, uncompressed.

  11. Re:That's solved at a lower level on Apple Releases Major iTunes Update · · Score: 1

    You can't always use them. You don't necessarily have space, money, or the ability to add a PLL (which is cute, by the way - PLLs are a nice source of jitter when used to do clock recovery). How sure are you my application can tolerate group delay more than a couple wrong bits (hint - audio would generally prefer the wrong bits to the group delay).

    Acknowledge that it's a problem, please, because it is. I'll happily acknowledge that the audiophiles are full of shit, but jitter exists, is a problem, and doesn't always have a solution.

  12. Re:That's solved at a lower level on Apple Releases Major iTunes Update · · Score: 1

    It's channel bit error caused by clock jitter. Checksumming works up to a point, but I've worked on systems where clock instability was causing data corruption on the data bus. In addition, as clocks run faster, capacitance and inductance play an ever greater part, and without careful circuit optimizations, can result in heavily rounded clocks. Heavily rounded clocks can significantly increase jitter, especially in double-pumped data buses.

    I'm not talking about sending a WAV file across the internet. I'm talking about the electrical pulses that represent that WAV going from the DSP on your sound card to the D/A. There's very little in the way of checksumming going on there.

  15. Re:This whole limit of computers... on Apple Releases Major iTunes Update · · Score: 1

    Sorry... jitter is NOT a myth, even fully in the digital domain. Now, the audiophiles blow it way out of proportion, but engineers do in fact worry about jitter all the time.

    Let's say we have self-clocked digital streams. Let's say we're detecting digital level in the middle of the digital pulse, in order to minimize possible jitter effects. If jitter approaches 1/2 clock, then it can and will effect the output.

    DAT systems, as you point out, RAM buffer, but those RAM buffered samples have to be sampled at time points; exactly how do you propose to have a digital RAM buffer that doesn't use discrete time points of data?

    Jitter can affect digital dubs. Jitter can, in fact, screw up anything digital.

  16. Re:dredging up the sedna debate on Best Images Yet Of Saturn's Moon Titan · · Score: 1

    Nah, the parent of my post defined planets as "things with atmospheres" in an attempt to include Titan and (inferring from the rest of his post, specifically his derogatory manner towards Pluto/Charon/Sedna) disinclude Pluto. I agree, a planet doesn't need to have an atmosphere; my main criteria is sized large enough to be rounded by gravity, and having an orbit (or in the case of near-binaries like Pluto/Charon, the binary center) around the star at the center of the system. Probably by my criteria Sedna is also a planet, and I'm fine with that - in other systems. And this is why.

    Personally, I think that Pluto should remain a planet solely for historical reasons, despite the fact that its right on the cusp of what ought to be considered a planet. Similarly, Sedna should never be recognized as a planet. I'm fine with setting the deadline to now. The actual definition of 'what is a planet anyway' has as much to do with history as it does with science, at least in the solar system. Put a rational scheme into play for other planetary systems, sure, but leave the 9 planets of Sol alone.

    I would say that both the wage demands and the safety rules are natural effects of collective bargaining. I don't think you can separate them, and while you can distinguish their separate effects, I don't think you can meaningfully draw a line between them.

    Safety rules are part and parcel of union activities. You can't have the one without the other; it's like trying to seperate the Iraq war's removal of Saddam from power from the casualties incurred in the process.

    No, the safety stuff is not a red herring, because its part and parcel of the discussion of unions. The union is what drove the company out of business in your discussion. Wages, safety rules, and all.

    And for what it's worth, I agree with you - there are good unions and abusive unions. Good unions are about fair pay for fair labor, and abusive ones are about as much pay as they can get for as little labor as they can do. Unfortunately, the same split exists among companies - fair pay for fair labor, and as much work as they can get for as little pay as they can get away with. Abusive unions and abusive companies counterbalance when they meet up with each other, to the detriment of everyone else, but when you get a good union at an abusive company or a good company with an abusive union, you know someone is getting screwed.

    Sure.

    Unions were one of the major reasons that things like OSHA exist; they pushed for safer working conditions for their employees.

    Unsafe working conditions in factories kill people.

    Would you argue that the working conditions today are much safer than industrial revolution era working conditions? A large portion of that change is due to union activity.
