  1. Re:They keep swapping the title on Milky Way Heavier Than Thought, and Spinning Faster · · Score: 1

    Yeah, I must have missed a memo, because last I knew they thought the Milky Way was half again the size of Andromeda. Granted I haven't paid *close* attention, but I was totally unaware that the consensus had changed to the Milky Way being "the little sister in the local galaxy group".

    I'm still not convinced that the distance-measuring methods astronomers swear by necessarily work correctly for extremely long distances. There's no way to experimentally confirm them, so we're working off of speculation built on speculation.

    I tend to trust the nearby distances (out to a handful of parsecs) as being approximately correct, because the parallax method, based on basic trigonometry, is also used to measure shorter distances on Earth's surface, and it works pretty well there, so unless there's something _special_ about *not* being on the surface of a planet that would make it incorrect somehow, or something special about larger numbers that would mess it up, it's probably fine. On top of that, we also used the same method for measuring distances to objects such as Pluto, and then we sent spacecraft, and they were able to enter orbit as planned, send back pictures, and so on. These distances are not as large as some of the other ones we measure via parallax, so I suppose there could be a decreasing reliability with increasing distance (beyond the imprecision we know about, arising from the imprecision of our angle measurements), but on the whole I tend to trust the parallax method as being more or less verified and the distances it gives us more or less correct.

    But once you get out past the limits of the precision of our ability to measure the angles, they have to resort to distance-determining methods that, to my knowledge, have never been experimentally tested. Red shift is a great example of this. How do we really know that objects whose spectra are shifted further toward red are necessarily proportionally farther away? Has this ever been tested? The theory sort of makes sense, but a lot of ideas sort of make sense until you attempt to confirm them and then end up being completely wrong. I'm not fully convinced that the astronomers *really* know what they're doing measuring distances at the galactic scale and larger, because there's no way (at our present level of technology, or for the forseeable future) to confirm any of the results.

    What I don't understand is why Mickey Mouse *needs* copyright extensions. Mickey's image is the #1 trademark of the Disney corporation, arguably more strongly associated with them than even the word "Disney", but certainly more than any other visual logo. I would think anything that even sort-of resembles Mickey should be protected as a trademark, so wouldn't that prevent anyone from making unauthorized Mickey Mouse cartoons, even in the absence of copyright protection?

    Okay, so somebody could distribute the extremely early Mickey cartoons as they stand, without modification. But is there really any significant monetary value in them (in that form) at this point anyway? I think all the real value is in the character himself, and the ability to use him in new material, and I would think trademark law would cover that.

    There's a categorical difference between ethnicity, which is inherently congenital if not genetic, versus what you are currently *doing*, which is a behavior issue. Being black is the former. Breastfeeding is the latter.

    Incidentally, the "feeding is necessary so bare breasts must be allowed" argument is bunk. There are innumerable ways to be relatively discreet with breastfeeding, even when you are in a public location, so that while people can tell you're feeding the kid, it's not a big public nipple display the whole time. This is what most breastfeeding women do anyway, on account of the fact that they have a sense of modesty. Covering up with a blanket is a common tactic, for instance.

    The people who want to post explicit breastfeeding pics on their Facebook profile aren't doing it because they want to be able to feed the kid when it gets hungry. They're doing it because they want to show off the breast. I don't see why Facebook should be required to publish such photos if they don't want to. Showing off bare breasts isn't in line with their publication policy. Freedom of the press belongs, after all, to whoever owns the press.

    > Interesting - that [Old English] appears to be closer to modern German... than modern English.

    Yes, it is.

    Modern English is a mixture of Greek, Latin, French, Middle English, and assorted other tidbits.

    Middle English was a mixture of various languages, chiefly French, Old English, Gaelic, French, Latin, and French.

    Old English was a mixture of Old German, Danish, Gaelic, Latin, Old Norse, and I'm not sure what all else.

    If you look at it another way, the vocabulary of modern English is about 30% Greek, 30% Latin, 30% French, 5% Germanic, and 10% Other. (Neologisms are mostly built on Greek and/or Latin roots, but a few of them fall into the Other category, e.g., "cromulent". Foreign words from other languages are also included in that 5% Other. Oh, and the reason it adds up to 105% is because some French roots are also Latin roots with the same meaning, and the corresponding English words can be seen as coming from either or both. There are also a few cases of similar overlap between Latin and Greek, e.g., "duo".)

    Now, granted, the 5% of our words that come from Germanic languages account for a disproportionately large percentage of word *occurances*, because the extremely common words like "from" and "of" and "have" are almost all of Germanic origin, as well as a high percentage of the more-common-than-average words like "man" and "throw" and "talk". Less common words mostly come from the other languages, though. "Scoliosis" and "sarcophagus" are from Greek. "Rendezvous" and "rouge" are from French. "Annual" and "pulchrous" are from Latin.

    A lot of the basic grammar also comes from the Germanic side of things, but with significant influence from Latin, and a good deal of "drift" has occurred over the years.

    I dropped primary support for IE6 back in 2005, when it was clearly far too old to consider current any more. This was right around the time that IE7 Beta became available, and I think I may have used that as an excuse, but honestly I almost certainly would have dropped primary IE6 support before very much longer whether there was an IE7 in the works or not. It was just too far out of date to continue supporting.

Everybody who's still regularly testing your site on pre-1.0 Mozilla releases, raise your hand. It's absurd. Frankly I'd be fairly surprised if anyone is still supporting Mozilla 1.5 at this point, and that's two years newer.

    I do still support IE6 to the same extent I support any other obscure and/or ancient browser, i.e., I try to maintain a basic level navigability for all browsers, but I make no claims that it will look as good or work as well as it's designed to do on something more modern. The layout will probably be wrong in IE6, colors and other styles may be applied incorrectly, and features that rely on client-side scripting may not work properly; I don't test with it thoroughly or on a regular basis. This is the same level of support I give to things like Lynx, Navigator 4.08, NetPositive, ...
