Your answer here is clearly wrong, as light reflected from the planet would be completely washed out by light from the star. I believe the other responses are correct which state that it is light absorbed by the planet's atmosphere that is analyzed.
I read that actually, I just wasn't aware that the differential in absorption across spectra was significant enough to do meaningful spectroscopy on the the planet atmosphere. Apparently sometimes it is, although the article didn't really explain that.
It was my understanding the exoplanets are detected by analyzing the "wobble" of the star that they orbit. How is it possible to determine anything about the atmosphere of the planet?
The article is supposed to be a tutorial, presumably for people who need more handholding than that. I guess it must not be a very useful tutorial, since all it seems to do is badly summarize the instructions.
The article only tells how to install iptables, squid, and Dan's Guardian. It doesn't tell how to customize it to your own tastes or values. Here, in full, is all the article says about customizing the filter:
While Dan's Guardian provides an excellent filter all by itself, you may want to exercise further control over the Web filtering by editing the other files in the/etc/dansguardian directory that contain external blacklists. Blacklists from squidGuard and URLBlacklist work perfectly with Dan's Guardian. Each file contains a brief explanation for its contents to make configuration easier.
So what we have is a case of relying on "Dan's" ideas of good and bad, rather than a commercial company's. Not a huge improvement on the face of it if parents are just going to install an open-source tool rather than a commercial one. Better yet would be to educate the kids and monitor their behavior rather than trusting some blanket censorship tool, open-source or not.
Is any besides mono developers user mono yet? The screenshots are pretty but why haven't I seen a single mono framework or C# app come to the linux desktop in any of the major distributions?
But C# hasn't exactly exploded on the Windows desktop yet either so I suppose it's premature.
Good point. For that matter, one can easily randomly generate datapoints that fall in any distribution through a simple numerical method, just by "throwing darts" at the graph of the distribution and keeping those points that fall below the line.
All kinds of nonrandom data follows the Zipf distribution, not just written texts. But the relationship between music and language is interesting nonetheless, especially when you consider the psychological aspects, for instance language learning versus music learning.
Yes, but I bet the phrase goes further back than those ads. 98 pounds is still seven stone, and most likely the ad picked that phrase from common usage.
First of all, Mexico is part of "America." I think you meant to say, "In the USA", which is the best you can do considering your country doesn't even have a real name. I mean, "United States of America?" How is that a country name? "Spain" is a name. "Mexico" is a name. "Group of Asian Regions", or "United States of America", or "Confederation of European Provinces" are not country names. But I digress.
I'm going to call you on your flamebait. Consulting the CIA World Factbook, I find that the "name" of Mexico is actually "Estados Unidos Mexicanos"--my God, that's not United Mexican States, is it? Most countries have a long form of their country's name which may or may not be in common use, in addition to a short form. In the U.S.A., "America" is our short form. Yes it may be ambiguous, but if you can't deal with some simple ambiguity that's your problem. In Africa there are two neighboring countries named Congo now--there's the Republic of Congo and the Democratic Republic of Congo. Sure, U.S.A. isn't the most elegant country name, but it's hardly the worst. Need I recall the S.S.S.R.? (Perhaps not the best example seeing as it didn't last very long, but who's to say U.S.A. will last longer.)
What??? You don't have "7 stone weaklings" over there?
Nope. We have 98-pound weaklings and we don't even know why we call them 98 as opposed to 99 or 100. Perhaps the imperial stone is still embedded in the American consciousness somewhere. Although it does occasionally get corrupted to a some other number in the 90's, a quick Googling shows that the 98-pound weakling reigns supreme.
It would probably be cheaper for most people to just grab some stock old desktop PC. For this purpose even an old 386 with a 100MB hard drive would be fine. Install a modem and an ethernet card. Install OpenBSD, Linux, whatever, and configure it as a bridge, NATed firewall, whatever you want. Stick the ethernet side into a hub and you're good to go. A headless old 386 or 486 ought shouldn't run you more than $30, and you could stick it in a closet or under a desk somewhere.
A workaround if you can't get the CD is just let the damn thing get the virus, and when the "reboot counter" starts up, turn back the clock two hours. The counter will change from 30 seconds to two hours and 30 seconds and you'll have time to get the definitions and updates. Once the system is up to date you can deal with the virus. Sucks but I've had to do this on more than one occasion for some hapless Windows users.
Hey, I'll sell you a Winmodem for $80, be glad to! Why not look at the brand or the friggin specifications instead of just the price tag? Pretty much any Hayes-compatible external modem should work well, infinitely better than any Winmodem, and top-notch modems that last for years and years can be bought on e-bay for a lot less than $80.
Besides, satellite service often only works in tandem with dialup anyway--you use dialup for your uplink and satellite for your downlink, and you still have to pay for dialup access. How much does that suck?
As mentioned by others a decent internal modem is just as good as an external modem. The other advantage a real modem has over crappy windmodems is that you get to offload all the processing to the modem. After all, all that realtime DSP stuff is what the modem is supposed to be doing anyway. Even though it doesn't consume that many cycles, the fact that winmodems require realtime access to the CPU can have a huge impact on performance.
How much is getting a job worth? Unfortunately for the competent job-seekers out there, too many positions require or prefer certifications as a prerequisite, as the author evidently acknowledges. Sure there may be employers out there who look past certifications, but in today's job market who can afford to take chances?
I can't RTFA to see how much the bounty is (slashdot effect), but how much do you want to bet that nobody will collect? One month and a half to provide a driver for proprietary hardware isn't very long if you're working on it in spare time, and I honestly doubt that the bounty equates to a decent hourly rate. Why such a short timespan?
I guess it just depends on your paranoia level. I'm happy enough to use secure webmail with a throwaway password at an internet cafe.
The bogeyman could be videocamming your laptop's screen and keystrokes too for that matter, if you're working with something so ubersensitive you probably shouldn't use an internet cafe at all.

There's a university in Las Vegas? And I thought UPenn was a party school...

Thanks for clearing that up.
