Part of the reason for this is that standard flourescent tubes are not full-spectrum. Tungsten bulbs may or may not be natural daylight-balanced (daylight-balanced are bluer & also more expensive), but at least every part of the spectrum is represented. Not true with flourescents, unless you pay out the nose. I don't know what the spectrum on white LEDs looks like, they weren't yet in vogue when I was a photo major.
Where the issue is security, the RFID cards are used to keep doors unlocked unless a card is read to unlock them. This seems to be much more about tracking the comings & goings of students who already belong.
Kind of interesting, since school security has two main concerns: keeping students where they belong (but with enough flexibility to allow them to leave for doctor's appointments, etc), and keeping out people who don't belong-- the divorced parent who lost custody but is determined to keep their child at any cost, for instance.
Oh well, it's not like minors have rights in the US, so the schools are pretty much free to do what they want in this regard.
I realize this is going OT, but wth, I've got karma to burn.
I simply don't understand the attraction so many/.ers have to Farscape. The plots are overly simplistic (although at least they're better than Hercules in Space, aka Andromeda), and frankly-- I got tired of watching Jim Hensen's muppets years ago. The acting is flat, the directing is stale, the special effects are standard industry fare (by which I mean that they don't suck, but they're not about to win any awards either), and the premise is just looney.
Each time I've tried to watch that show I've wasted a good fifteen minutes (as much as I could stand before I started throwing bricks at the TV) of my life that I can never get back.
Mostly agreeing with the previous poster here-- the proposed break-up would have put the OS in one corp, the browser in a second (not sure if that included IIS & its supporting apps or not), and Front-end apps such as Office in a 3rd.
So instead of one enormous monopoly, we would have had three large monopolies. Hardly an improvement.
I do, however, wonder what would have happened had MS been forced to divest itself of Office, IE, IIS, etc, and split the remainder of the corporation into three parts, each starting with the same rights to MS's legitimate IP (with a special controller appointed to advise on what patents to throw out based on prior art, etc).
The remaining companies would still have had a near-monopoly on office suite software (let's face it, StarOffice/OOo is nowhere NEAR cracking that egg yet, in terms of market share), but the OS monopoly would have been gone.
Much like any other *nix distro, FC3's documentation consists of the man and info pages. The information is very useful if you already know what command or function it is you need, but much less so if you only know in general what it is you're trying to accomplish.
I find that the best information comes from googling a phrase that describes the general information (i.e., "establish POP server using Linux sendmail"), then using the specific information garnered from that to figure out which man/info pages to read.
In other words, except for the cases where a specific package is unique to the distro (and I just can't think of any here), the built-in documentation is only a second-stage process as far as I'm concerned.
Hope this helps.
Yeah, there's something I forgot to say in that previous post-- I'm -horrible- at trying to imagine what happens to forms when shifted in three dimensions. On standardized tests, I (like most/.ers, I imagine) score very highly in nearly every category-- but when it comes to spacial relations, I'm well below average. So the fact that I could solve -either- of those puzzles on my own tells you they -had- to be easy.
I don't remember how long it took me to solve the Missing Link puzzle, but I remember finding a pattern that would solve it if I just kept repeating the same moves over & over again-- I actually started keeping track at one point, and discovered that it never took more than 70 iterations of the pattern to solve it.
The Pyraminx I bought in an airport shop in Frankfurt when I was 13 years old, right before we left to return to the states. I had it solved (again, with a repeatable pattern that solved it if I just kept repeating it) before we landed in New York.
China isn't the only country with this problem. We here in the US have the same problem, albeit that the fires here haven't lasted as long-- only 30 to 40 years instead.
China has one great advantage that makes it easier for them to accept Kyoto. Since they don't have the existing infrastructure for petrol (except around major cities), it's a lot more palateable for them to make the investment in alternative fuels -now-. We in the US, however, have billions (if not trillions) of dollars worth of infrastructure to maintain as we try to move to alternative fuels at the same time. Economically, the Chinese leaders have made a difficult but smart choice-- agree to Kyoto & put the money in to developing the infrastructure to support their economy in the future, rather than investing in dinosaur-blood tech that (we ALL hope) is going the way of the dinosaur.
Yes, that quote is from Timothy etc, but please-- I'm not bible nazi, bible banger, bible anything. For the most part I consider it a poorly written and poorly documented history of a tribal lifestyle that blended myths from dozens of unattributed sources-- NOT a guideline for living today.
I'm familiar with large parts of the bible only because I read -a lot-, not because I believe what I read.
And coming from a quotes & grammar nazi, I point out that the actual quote is not "Money is the root of all evil," but instead, "The love of money is the root of all evil."
So therefore, following that same analysis, "Women = Love of 2((Evil)^1/2)"
Worse, however, would be a message saying "We survived, but all the other civilizations to which we sent this message perished shortly after receiving it. Apparently the very knowledge of sentient life, apart from their own, so violated their religious principles that they self-destructed."
This is, of course, assuming that any ETs actually -have- religious beliefes.
You don't say it in so many words, but from your post I get the feeling that you're under the impression that Linux is effecting the total number of copies of Windows sold. I doubt this is true-- the raw number keeps going up. It's the proportion of the market that uses Windows that's going down, if only so slightly yet, as many people switch to Linux. The profits, however, are made on the total number of copies sold, not the market share.
My apologies if that's not what you intended to say. I don't mean this post to be argumentative.
Interferometry of this kind is (with current technology, but even in principle) only conceivable with radio astronomy, not with optical astronomy.
Perhaps I'm reading this wrong-- or misinterpreting what you mean by "this kind". The WM Keck telescopes in Hawaii-- visible light scopes-- already use interferometry.
The principle is exactly as you describe, with timestamped data being combined on a separate processor.
Interestingly, other arrays (planned or already existing) that are designed to search for other types of signals-- such as LIGO-- use the same principles. In this case the quarry is gravity waves (predicted by theory but not yet detected), but it works by interfering the results of two linear beam detectors. When a gravity wave moves through (in theory), it disturbs the beam in one arm of the L-shaped detector more than the other. Since the wavelength is calibrated to normally exactly cancel, knocking it just slightly off-kilter will result in the sudden detection of a signal. Multiple installations are scattered across the world, partly so that each can verify the results of the others, partly so that, in the event that a wave is detected, the timestamps on the interferometers can be used to triangulate the source-- much the same way that seismologists triangulate the epicenter of an earthquake.
Sorry about these amazingly long run-on sentences!
Interferometric telescopes can drastically increase the resolution as compared to single-tube telescopes.
Having two scopes one mile apart, as far as resolution is concerned, is equivalent to having a single one-mile-wide mirror (in essence; the previous poster is correct in his argument about atmospheric distortions & other problems).
The problem is that the amount of light collected is still based solely on the sum of the surface areas of the mirrors-- not the effective area.
If not enough light (or radio waves, in this case) is collected to trigger the CCDs, the object throwing out the radiation simply won't be detected.
Incidentally, the Keck telescopes in Hawaii work this same way, but with a much shorter baseline. It helps that, at two miles above sea level, they're above much of the atmosphere, and that they both have fairly large mirrors to begin with.
For more information about how they work, Google lists plenty of resources.
sometime in the late 80s or early 90s, the Washington Post reported discovery of another large mushroom, this one somewhere in the northern Plains States (Minnesota or Wisconsin maybe, not sure)...
The headline to the article was "There's a Humongous Fungus Among Us"
Um, maybe events like this (which occur at regular intervals of 17 years, for Brood X) aren't reported loudly outside the region in which they occur, but for about two months it was any of the talking heads on radio & TV would talk about in Northern Virginia.
If you've never been in the area effected by Brood X during mating season, it's an amazing sound. Sort of like a 1950s era B movie soundtrack. Actually I heard a rumor (no verification, I have no idea if it's true or not) that that sound was actually used in at least one movie.

I know your message was in jest, but I can't not respond.
The two large land acquisitions to which you refer are the Louisiana Purchase and Seward's Folly (the purchase of Alaska, in 1867). France sold the Louisiana Territories to the US in order to finance its war with England. Russia then did the same thing with Alaska (and also to reduce its need to fortify the Peninsula, which they were never really able to maintain to begin with).
The only thing that surprises me is that Russia didn't try to sell Alaska fifty years earlier, when the money would've helped in their war against Napolean.
The two other major land acquisitions in the 19th century were Texas (which, incidentally, the northern states didn't even want to admit to the union, and wouldn't have happened at all if the Texans hadn't asked to be annexed-- although it's not like the US didn't play some pretty high-stakes political games to make that happen), and the Spanish American War.

Speaking of TMI, here's a trivia question for you: how many deaths or cases of serious illness have ever been attributed to the accident there?
Answer: zero. zilch. nada. not a single one.
Ack, NOooooooo!!!
