  1. Re:I'll believe it when I see... on Warp Drive Might Be Less Impossible Than Previously Thought · · Score: 1

    I'm mystified as to how you can relate so much detail and yet miss what I was saying.

    Two ships travel at c in opposite directions for a period of time. When they decelerate and return to the same frame of reference that they started from, the distance between them will be equivalent to one ship having travelled at 2c for the same period. It doesn't matter what the people in each ship perceive from within their reference frames while they're moving.

    This same effect is why the sky will eventually go dark—the universe is expanding at such a rate that light from the furthest side will eventually never be able to catch up to us. I.e., the relative velocities are above c.

    Not to put too fine a point upon it, but that doesn't affect my argument. If you have two ships going c in opposite directions for 1 hour, and then they stop moving, the distance between them will be twice that if only one was moving. You can replace 'absolute frame of reference' with 'starting frame' or 'parent frame' if you really need that itch scratched.

    You're picking at semantics and missing the point. If you're standing in a room and shining two beams of light away from each other, the photons appear to have a net velocity of 2c. Nobody's exceeding c. If you were inside of one of the beams, the other would look weird to you, sure, but that's due to time dilation. If we were to replace the beams of light with two ships, you'd still be able to cover twice the ground relative to one another. For practical purposes, and not the gratification of the people who feel an urge to measure how fast things are moving while in transit, the parent frame perceives you getting to your destination twice as quickly as you otherwise would. I think. (IANAP.)

    Er... no, away from each other. The net velocity is 2c.

    I don't think you quite understood—the relative motion would be FTL, but so is the relative motion of two beams of light going in opposite directions when measured from an absolute frame of reference. That gets you up to 2c. No time travel. Hilarious amounts of dilation, sure, but nothing wibbly-wobbly.

    It sounds like you really just need more staff. In Canada we generally have the results well before morning, with poll stations closing as late as 9 PST. Comments on this story from German and South African voters suggest that it takes them about 6-10 hours as well.

    ...that being said, your absentee ballots are probably more technically complicated than the very basic "fold, tear, and chuck" ballots we use in Canada. Damage to them is comparatively rare since they're only in the voter's hand for two minutes, and you can always ask for a replacement.

  11. Re:Have? on No Opt-Out For Ads On New Kindle Fires · · Score: 1

    It's almost a tragedy of the commons—companies are so hell-bent on forcing advertising on consumers that an increasingly large portion of the population will go to extreme lengths to make sure that no advertising of any sort has any effect on them. If only we could take the colossal intelligence that went into developing Google's advertising infrastructure and actually grant some of it to marketers...

    Unfortunately, the Unix philosophy doesn't make that good of an end-user product, at least as far as modern marketing knows. It's the inclusion of little details that make or break a sale and allow a company to beat the competition.

    I don't think they're making any claims about her nerves system being the same as anyone else's; all of the talk in the press release is specifically about dealing with her case. Think about it for a moment—this technology's going to be used for dealing with damaged eyes for a long time much like those of Ms. Ashworth, not healthy optic systems. Perhaps they're taking on a non-minimal test case, but it's really an extremely topical one.

    Woah, woah, woah—I'm not a Star Wars person at all. And I doubt the BBC, who just said "Tatooine" in their headline, assumed everyone would be. It's a much more neutral statement about willingness to accept references one might not get. If you want to put it to fisticuffs, though, I personally think the reference should be left out entirely; 'binary star' or the even more basic 'twin star' would do the job just fine.

    Unfortunately the concept of zeal disparages them for believing in their cause, and is an innate slur against other members of a given movement. A new word, more specific to the idea that they are acting against their own interests, is necessary. 'Radical', in my opinion, has the same problem, since it implies their belief is, again, more essential.

    Absolutely, when progress is hindered, activism, and perhaps of an extreme sort is necessary for any cause. I wish to heap blame on those who would rally prematurely, though, and in doing so endanger their movement. Extremism can be good, but jumping ahead out of turn harms everyone. At this point in the game, we're still convincing people that free culture is socially and economic viable—and this SfFC member is already calling for the CC to take on an exclusionist attitude toward people who are just dipping their toes in. That's not helping anyone; it's spiteful and downright moronic.
