If I mix 1 L water at 20° C with 1 L water at 40°, do I get 2 L water at 30°, or is it somehow more complicated than that? How about 500 mL 20° with 1 L 40° - would I get 35° water? Or would it take 1.5 L of 40°? I feel like high-school chemistry prepared me for this, but all I remember is PV=nRT, and I don't remember how I'm supposed to use 'n' in this situation.

I mean, maybe aim for a parasol instead of a rain umbrella, but the fact that these things exist mean that they're not too horrible, right?

Anyone know how the law surrounding MP3s works in the United States? I know that the format is proprietary, but that it's permissible to encode things in MP3 format for personal use. When looking up licencing costs, it appears that you can buy a license to A) Have your software encode/decode MP3s, B) Stream MP3s, or C) Include MP3s in a game. I want to encode some personally recorded WAVs as MP3s using the LAME codec, and offer them for download from a for-profit business website. I am not making money off of the MP3s themselves; however, I think they add value to a service that I provide, which I am making money off of. As far as I can tell, the actual patent surrounds the encoding and decoding of the MP3s - if I'm not doing that, I'm in the clear. And my business model certainly doesn't revolve around the encoding/decoding process; I'd do that once, and stick the files up for download. I'm not sure if I can use the LAME codec, though. Anyone have any idea or experience in this matter? I could put my files up in a WAV codec; however, my files end up about 15-20x larger, and this costs me both in bandwidth and degraded user experience.

Why is Greece (the country) called "Greece" in English? Looking at Google Maps, it looks like the local name for it is "Eλλάς", which (I think) would be pronounced "ellas" or "hellas", which isn't even close to "Greece." Where'd out name for it come from?

Clockwork Sputnik posted:So I was watching a show on the Science channel narrated by Morgan Freeman. It blew my loving mind, but Mr. Freeman made it somehow feel like a gentle hug. Are you talking about the Observer Effect, or something more specific in quantum mechanics? As for what "counts" as an observer, as far as I can tell, that's been vastly simplified (and, in the process, anthropomorphized) from whatever the hell is going on physically. I think the actual interpretation is closer to that a particle is in superposition relative to another particle until the first particle has a measurable (and measured?) effect on the second. I am not a quantum physicist, though, and you'll probably get much better answers over in the Science, Academics, and Philosophy form.

The Bramble posted:Whats a good way to estimate the average wattage used by my PC? I have a 500 watt power supply with a core2 duo processor and a modern ATI video card. I know the 500 watts is a maximum and that I likely never hit it even when playing games, but I'm wondering what fraction of that I'm actually using while browsing the internet, or playing a graphically intense game. Most reliable way is with a "kill a watt" - a ~$20 device that you plug into the wall, then plug your PC into. If you're not looking to spend any money, I guess you could try to eyeball it from your electricity meter, but that's significantly more prone to error.

Seems like putting codes in like trade chat in WoW would be an easy way for spies to communicate. Yes, they can. Due to a 1994 law called the Communications Assistance for Law Enforcement Act, all ISPs must have the technical capacity to wiretap an individual customer's internet connection, in case they are served with a warrant to do so. You can encrypt your online communications, but anything less than 256-bit is going to be torn to shreds by those NSA weenies in minutes. There is legislation in progress that would mandate that any communications software capable of encryption install a backdoor for government officials to use. This is a bad idea, will be used by hackers to gain access to your encrypted data, and won't prevent terrorists from owning and using illegally encrypted P2P communications programs.

So if I poured a cup of the same size of something that was 70 proof, would it be the same as drinking nearly 9 beers? That doesn't seem like it's right to me. Yup. 16 Oz of whiskey contains as much alcohol as 9-11 pints of beer. (Don't drink a pint of whiskey.) The typical rule is 1 "drink" is a pint of beer, a glass of wine, or a shot of hard liquor.

Arakan posted:idgi It is impossible to "enhance" an image. The image, right now, is as detailed as it can be. The computer doesn't know what to fill in the missing pixels with when you try to double the resolution. It can guess, but it won't do a very good job, because unlike you, it doesn't see an object in the picture, it just knows that there are different colored dots next to each other. It can fill in by picking a color in between all of the nearby colors, but this results in a "fuzzy" looking image, because where you'd expect sharp borders, you get an extra pixel of in between color. Your best bet is generally to find a better/larger starter image than you'll need, and shrink it down from there.

Sorry for the crappy MS-Paint illustration, but it's all I've got. In the above picture, the light-grey axis is what the wheel is spinning about, but the red dot/line is its center of gravity. The dark-grey half-circle is made out of something relatively heavy. When it spins, inertia wants to keep it fairly steady about its center of gravity, but it's forced to spin about the light grey axis. It compromises, and shoves the axis in the opposite direction that the wheel's mass shifts. The axis is in turn anchored to the body of your cell phone or your mom's vibrator, which causes that to move in tiny circles opposite the direction that the wheel is spinning.

wigtrade.cc posted:Can the network at my dorm throttle .torrent files? It's possible, yes. It's also possible that wherever you're downloading the .torrent file from is just serving files more slowly than other websites where you're downloading other files. If you want to test it, get a 25k file, say an image or something, and rename it from image.jpg to image.torrent. (It's not really a torrent, but your university's firewall might mistake it for one.) Host it somewhere that's not going to change the extension, or maybe just email it to yourself. If your university really is shaping downloads based off of file extension, this file will take as long as your real torrent files to download. Tangentially, I'd be careful torrenting things when your University is your ISP. The labels/producers/etc seem to like targeting universities, and a HUGE percent of the time your uni will hand over your info without so much as a warrant.

First off, if you're working on the web, C++ is not the language for you. You'd want something like PHP, ASP, or Java (with JSP) for your logic, and some flavor of SQL to cover databases. If you want interactive pages, you'll need JavaScript. (Not the same thing as Java.) XAMPP is a popular base for web-development - it's a binary install, and comes with Apache, MySQL, PHP, and Perl. The best way to learn is to pick a project that you actually want to accomplish, and then figure out how to do it. There are tutorials on the internet, and once you've got the syntax of a language down, the language documentation is as just as useful as any guide or lesson you'll find out there. You might also want to stop by The Cavern of COBOL programming form for better help than you'll get here.

Elijya posted:The same thing that keeps the helicopter from responding to your TV remote, or for your car radio to pick up air traffic control. They operate on different frequencies. To expand on this, a single antenna is usually optimized to work for a single frequency. It's possible to add on a software (or hardware) filter to extend the range of an antenna - this is how your car radio works. However, the range that a given antenna will operate at is not infinite. Furthermore, antennas are designed so that, for a given configuration, it will only pick up radio waves from a very narrow bandwidth; this is what prevents radio stations from bleeding into one another. Your phone is listening very specifically to the spectrum that it expects cellular signals on. If it were listening to a wider bandwidth, there would be more noise on the signal, and with digital applications, anything past a certain threshold of noise means no operation whatsoever.

It seems like every week, we have some big production issue with it - the new version of Oracle doesn't like our old PL/SQL code, a memory leak is crashing production every 35 hours, some minor configuration issue just became a big problem, etc. Is this normal for Oracle databases, or am I just on a team of losers? If it is typical of Oracle, are other database products like this, too? Do MySQL and MS SQL server constantly need some sort of tweaking and/or upgrading? I'm pretty new to this, so take it for what it's worth: MS SQL has a different (smaller) set of functionality than Oracle or MySQL, which can mean massive re-writes, and it tends to be buggy. Oracle tends to be finicky. MySQL is also buggy, but it has a very well documented set of bugs. Uugh, this is mostly hear-say; I've only ever seriously used MySQL. (And it's far less of an issue on our system is than Tomcat is.) You'd probably be better off re-posting this questing in SH/SC or Cavern of COBOL.

The average college student changes majors three times. No one knows what they want to do. You eventually pick a degree, graduate, and then still don't know what you want to do. You get a job that you're not sure is what you want to do, and you do it for a while, and maybe you change your mind in the middle. If you're waiting for that magic revelation where you stop being a teenager and start being an adult and everything makes sense, it never happens. Sorry.  That being said, there are some pragmatic steps you can take to get the best value out of college. If you're considering Engineering or Premed, at all, stay on course for them while you figure things out. Your Math and Science credits from those courses will count towards generals, but if you take the easier Math-and-Science-for-English-majors classes, and then decide that Engineering is your thing, you're going to be a semester or two off-course to graduate in time. If that's not a concern, do a breadth-first examination of your generals/core classes that you'll need to graduate no matter what you major in. Take a 1000-level science, speech, and literature, and math class next semester, whatever you aren't taking now. These are good introductions to the majors that they represent. If you hate Calculus I, Engineering is not for you. If you think reading poetry is a waste of your goddamned time, you might want to steer clear of the liberal arts. Look, I know it seems scary now, like you have to make a decision that's going to determine the rest of your life. And you know, eventually, you are. But there are no wrong answers. There's not one perfect future out there waiting for you; you're not going to mess things up by missing out on it.

Manslaughter posted:I know very little about nuclear bombs and whatnot but playing Civ today got me thinking about a pretty scary question. A modern thermonuclear warhead is 50,000 kilotons, which is about 2000 times more powerful than Little Boy. Whipping out a bit of math, 5e4 kilotons x 4.184e6 J/kt = 9.204e15 J = 5.24e10 kg m/s2 The moon is 7.36e22 kg, according to google. This means that 1 modern warhead could accelerate the moon 7.12e-13 m/s2, given a perfectly efficient transfer of energy. There are an estimated 11,825 nuclear weapons on earth. Assuming ALL of them are as powerful as the most powerful nuclear warhead, and they're ALL detonated at the same time on the moon, and there's PERFECT transfer of energy, the moon might be accelerated towards the earth at speeds of up to 8.42e-9 m/s2! Gravity accelerates the moon towards the earth at about 2.3e-3 m/s2. All of the nuclear might of all of the nations of the earth is less than a millionth of the force that gravity exerts between the earth an the moon. I'm sure I made a mistake in my math somewhere, and I know I made some stupid assumptions. Still, no one's going to be smashing the moon into the earth by blowing it out of orbit, any time soon.

Your hands/face are the most likely infection vector; the parts of your rear end that touch a toilet seat are all on the outside of you, and germs need to find a convenient path to the inside of you. Those paper covers are mostly there to make you feel better.
