    This is also backed up by the fact that we have 3-color vision, which you need to see ripe fruit, where as hunters like cats and dogs see in black and white.

    This is a common misconception, but false. Most mammals are dichromats: they have two different color receptors, with peak sensitivity at green and blue wavelengths. We have three, with peak sensitivity at yellow, green, and blue (the yellow receptor is commonly referred to as "red" because it is the only receptor capable of responding to long wavelengths and therefore essential for the perception of the color red, but it's actually most sensitive to yellow).

    So most mammals are color blind in the same sense that the average color-blind person is -- they have reduced color discrimination relative to us, but that doesn't mean they see in black and white.

    Ok, it turns out that the filesystem is mounted at the root rather than under /Volumes, and that I can indeed move the mount point around. The zfs command seems to mostly work, but I got a couple of kernel panics while playing with it (most recently from trying to destroy a snapshot). So, while the fact that ZFS is coming is very exciting, I don't really think it's worth messing with at the moment. It's far too flaky to trust with any meaningful data, so beyond a "cool, it's going to work eventually!" there's not much else to do with it.

    In this forum they duiscuss build 9A326 and ZFS. Some posters mention, that you can choose ZFS but it doesn't work (yet) and/or that you can't install OS X on it.

    I'm running 9A326, and I can confirm that while ZFS does indeed show up, it basically doesn't work at all. It's possible to (if the planets are properly aligned) format a partition ZFS, but it's incredibly unreliable -- I've gotten hangs, kernel panics, long delays trying to mount the drive, and reports that the drive is unreadable. It shows up on my desktop (with a folder icon rather than a volume icon), and it won't let even my Admin account modify it without authenticating. The filesystem doesn't show up under /Volumes, the physical disk no longer shows up under /dev... the list goes on.

    But at least when I copy data into the "folder", it's unquestionably ending up on my ZFS-formatted external hard drive, so at least that much works. However, it's as far as I can tell pretty much impossible to "really" use due to the permissions issues. Some actions, like deleting files, don't give me the chance to authenticate, they just tell me I don't have sufficient permissions. Normally I'd just use the command line, where I can sudo, but because the drive doesn't show up under /Volumes, I don't know how to access it from the command line. I haven't yet tried using the zfs utility to specify a mount point for it, but I did verify that zfs' man page specifies a default mount point of /Volumes/<fs>, so it should already be there.

    Of course, none of this should be taken as a complaint against Apple. They never said, even in the developer seed notes, that ZFS was working yet, so it's hardly surprising that it's so broken at the moment. I have no doubt that it will be rock-solid by the time Leopard ships, and I can't wait. Honestly ZFS is the most important new feature in Leopard from my perspective... and if they just get Time Machine working with ZFS snapshots (instead of separate copies as it does today) then I am in OS nirvana.

    Apple's attitude towards many FOSS standards vacillates between indifference and hostility.

    For example, they view X11 as a dead end and want to actively convert people to using Cocoa; hence, Apple's X11 support sucks and they have no interest in making it better.


    You mean Quartz, not Cocoa. And Quartz is unarguably far more powerful than X11 as well as faster; I think they're absolutely correct in promoting it over X11. I'm not sure what "sucks" about their X11 support, as it certainly seems to work just fine on my system.

    OpenDoc compatibility would be natural for Pages and Keynote, but I suspect apart from being a lot of work, they don't want it: Microsoft Word matters commercially, and they likely view OpenDoc as supporting FOSS competition (since NeoOffice is actually quite sweet on MacOS).

    People still use OpenDoc? Wow. I rather thought it was an experiment gone horribly, horribly wrong.

    As for ext3, I think there are two reasons. First, using ZFS, Apple has a feature-list advantage over ext3 (never mind that that doesn't translate into any real world advantages).

    Are you seriously -- SERIOUSLY -- suggesting that ZFS has no real-world advantages over ext3? That crosses the line from "Linux advocate" into "bat-shit insane".

    Second, I think Apple really doesn't want to make it easy for people two switch between OS X and Linux; despite the bluster, they must recognize that Linux is a serious alternative to OS X, in particular given the current and upcoming releases of Gnome and KDE.

    Yep. I'm sure Apple is quaking in fear at the threat of Gnome and KDE. You nailed it.

    In a nutshell, the company just isn't committed to FOSS, they are just using FOSS when they see a short-term business advantage.

    Apple is the only organization that has managed to make Unix completely appealing and usable to average non-technical users. Yes, they chose to use a better graphics library than X11, and a better (also open-source!) filesystem than ext3 -- and good riddance on both counts, I say. Why all the hostility?

    To turn on full keyboard navigation, open Keyboard Shortcuts (under System Preferences / Keyboard & Mouse) and turn on "Full Keyboard Access".

The ^F1 shortcut can also be used to toggle Full Keyboard Access on or off without having to go into System Preferences.

    I'd love to know why my points are "poorly informed" -- a quick web search revealed mounds of support for them. And the only point you bothered to make is, of course, meaningless. I'm not suggesting that "a historical record from antiquity is inaccurate because it was written mere decades after the fact". I'm taking issue with the very idea that the gospels constitute a "historical record", as you put it, in the first place.

    Does every ancient writing constitute a "historical record"? Are Zeus and Beowulf and Horus all real figures, just because there are writings about them? Or should we use rational thought and realize the simple fact that the writings are obviously fictional in nature probably means that they shouldn't be taken seriously? If I wrote a story about a man performing miracles and rising from the dead today, you (quite rightly) wouldn't take it seriously. So why do people believe a handful of anonymous stories from two thousands years ago with similarly incredible claims? (I say "anonymous" because, as most Bible scholars agree, the authorship of the gospels is unknown. The attributions to Matthew, Mark, Luke, and John are apocryphal.)

    I am absolutely 100% serious when I say that if J.K. Rowling had lived two thousand years earlier, we would now be arguing about whether Harry Potter really lived or not. Jesus was not real. There is no historical (meaning non-fictional) evidence to support the idea that he lived, and the stories of his life are too similar to earlier myths to credibly claim coincidence.

    Most atheists "believe in Jesus". The evidence of his existence is diverse and compelling. Whether he was the Son of God or a 1st-century L. Ron Hubbard or somewhere in-between is the point of contention.

    Diverse and compelling? Such as? There is extremely little evidence of the existence of Jesus as a historical figure. The only documents which describe him were written decades after his death, and are obviously unrealistic (unless you view rising from the dead, walking on water, and transforming water into wine as "realistic").

    Furthermore, and most damning, is this: let me describe someone for you. He was fathered by God and born of a virgin mother. He performed miracles, including turning water into wine. He died and rose again from the dead and ascended into heaven, liberating mankind. Am I talking about Jesus? Nope, Dionysus. The mythological life of Jesus was obviously inspired by a number of other savior figures, including Osiris, Mithras, and Dionysus (and in fact ancient historians used the names Dionysus and Osiris interchangeably, indicating that Dionysus himself was inspired by Osiris). If you actually do the research, the number of parallels between these myths is staggering. So staggering, in fact, that early church fathers denounced the stories of Dionysus as having been spread by the Devil in order to cast doubt on Jesus, the true fulfiller of prophecy.

    "For when they say that Dionysus arose again and ascended to heaven, is it not evidence the devil has imitated the prophecy?"
    - Justin Martyr, church father, circa 150AD

    The point is that there is essentially no evidence for Jesus as a historical figure, and much evidence that he is an adaptation of earlier myths -- a newer and gentler Dionysus, if you will. Likewise, the myth of Noah was clearly inspired by earlier myths -- in one story, Utnapishtim survived a great flood sent by God to destroy everything on earth by building a great ark to save himself and representative members of each species of animal. Christian mythology did not arise ex nihilo, but is in many (perhaps most) cases just an evolution of earlier stories. It's interesting and it's important from a historical standpoint, but I'm hoping that at some point we can finally admit that we just made the whole mess up.

    The reason we sometimes say that laser beams don't follow the inverse square law is a bit of handwaving with respect to human vision. Suppose you have a tiny pinpoint beam of light entering your pupil. 100% of the beam's energy enters your eye. Suppose you now stand farther away that the beam is twice as wide upon entering your eye. The beam is now twice as wide, but it's still much smaller than your pupil, so 100% of the beam's energy is still entering your eye. The inverse-square law is fully in effect, but it (in a sense) doesn't matter because, due to your comparatively huge pupils, it isn't helping to reduce the amount of energy entering your eye. At a significant distance, where the beam is large relative to your pupil, the inverse-square law is much more apparent with respect to laser beams.

As for the pollution controls in cars, don't forget that car engines have to deal with an incredibly wide range of ever-changing speeds and power requirements. It's quite difficult to build an efficient engine which operates across such a wide range of speeds, but a simple engine driving a generator can operate at precisely one speed with a fixed load and can therefore be optimized for its precise requirements.
