'We' (human activity) emits infrared radiation (heat) and carbon dioxide (which traps infrared emitted by the Sun). If the source of heating you mentioned is indeed ultra-violet then it'll come from the Sun and would be above and beyond what we're doing.
Actually after using Java for a decade and a half I have never had the JVM crash on me due to a bug in the JVM. I have had Hotspot crash when I supplied bad pointers during JNI, and have had Out-of-Memory exceptions when I didn't change the default configuration. Otherwise I've never seen a JVM crash. Pretty amazing stuff (but then, Sun had fantastic engineers, just crappy [greedy] sales-folk who made buying Sun stuff unnecessarily hard and lengthy).
That musta been before 2005. Java is *very* fast now. If you read the following (2008) article from Gosling's own blog (ironic?) you see that Java easily beats C++, often beats C and nearly beats FORTRAN for speed. Shame your opinions on Java are so badly out of date as to be mis-informed (like so many on Slashdot). You're missing out on the great performance of Java, fast development times, huge amount of existing libraries, and true cross-platform (Windows, Linux, Mac). Here's the link for more information (and read the linked report by INRIA the French scientific supercomputing folks): http://blogs.oracle.com/jag/entry/current_state_of_java_for
Kinda right, kinda wrong (I guess you might not be a developer or might not have been in the enterprise software field when Java and later.NET first emerged, which would explain why you don't understand the considerable limitations of.NET). What actually matters is the millions of lines of code in the libraries. The language and language implementation is meaningless in comparison. Basically the.NET libraries only work on Windows and Mono have essentially declared that some libraries will only ever work on Windows (basically, Mono don't intend on implementing some minor things like, oh, WPF). In this context Java totally beats C#/.NET hands down. Sure, C# has some language nice-ities but they pale in comparison to the fact you can run Java almost everywhere (except the places that have forbidden it due to [IMHO, shitty] business reasons, the XBox and iPad/iPhone].
Incidentally the Scrabble reference was just a lame joke. But in actuality you are wrong with your attempted put-down. I do use Apple on a Mac Book Pro for ease-of-use applications, also use Linux (since 1993 I might add, which I use for development), and have some Windows game servers that I share to the world (DCS:A-10C and LockOn:Flaming Cliffs 2). I don't limit myself to one platform, although I like the the philosophy of the Free Software Foundation (having a personally signed copy of Richard Stallman's book which I bid for at an auction held by him).
You clearly don't understand the principles of signal modulation that allow a very weak signal to be transmitted even in the presence of strong noise. In fact, the usual GPS signal is extremely weak already at ground level and detectors very sensitive. Getting a signal directly from a satellite with noise below you should not be hard. This allows a receiver to pick up a signal even when a jammer is present, if you are able to hop frequencies (which I'm guessing a modern military system could do: a guess because it is likely to be classified as to the exact capabilities, but easy to implement in hardware/firmware). Then there is the fact that US GPS navigation systems can use both the encrypted and unencrypted GPS signals. Don't you think the designers of modern GPS systems thought through this scenario already? It is possible the aircraft involved had an older GPS/aerial system (ignoring the backup Inertial System and Dead Reckoning which every USAF pilot learns, so the aircraft was never in danger), most likely this is being used as a PR excercise to show how crazy the North are.
'Lebensraum'? Not now. The Israelis gave up the Gaza Strip voluntarily, trying to exchange land for peace. What did they get in return, an increase by two orders of magnitude of rocket attacks directed specifically at civilian targets. Sure the Israelis aren't perfect, and are often excessive, but you are clearly clueless about the true facts on the ground. Oh yeah, the Arab citizens already in Israel get treated the same as any of the large number of non-Arab citizens. Only the extreme Orthodox Hasidim are the real crazies, but then again I guess you selectively remember facts that conveniently fit your preconceived hypothesis (incidentally, I've been to Israel and neighbours, even meeting Hezbollah in Lebanon - I have a neutral view, but it is clear to see much of the Israeli actions are a sane democracy fighting for survival against unreasonable opponents).
Would be hilarious if an AGM-88 HARM 'malfunctioned' in the exercise and hit the transmitter. More worrying than the (easily countered) GPS jammer is the fact that they (and the Chinese, IIRC) have battlefield lasers for blinding.
Mate, I'm a New Zealander ('Kiwi') and agree with much of US foreign policy in the last decade (whether or not you believe in the toppling of Iraq, at least the US had enough sense to carry on to win, and fight crazies on other people's soil). Not all of us a myopic peaceniks with zero knowledge of history - in fact much of the commentary from our citizens runs counter to the official policy of our government and the sentiment of the majority. Again, it is the squeaky (and crazed) wheel that gets the attention. I agree that far too many Kiwis are pretty clueless in the reality of modern politics - sitting around a campfire singing kumbaya will not work with the North Koreans, Hamas, Hezbollah, etc - the biggest stick you can find does. Tarring us all with the same brush is pretty lame though. I certainly don't see all folks from the US as larger-than-life (in multiple ways) Texans, or hippies out in your western deserts, or slick Gordon Gecko types in the east. Sure, point out we have a disproportionate amount of clueless peaceniks, but no need to insult the rest of our country.
The technology to get these shots is no less impressive. Too bad many folks take such advances for granted, they don't even realize what an accomplishment is to get photos at this resolution and instead concentrate on the 'scandal' of the purported hoax. We don't deserve to rule this planet.
Which is just as well. For my devices the Windows drivers seem to crash an awful lot (compared to using stuff on Mac OS X or Linux, in my humble experience of late). This is not Microsoft's fault, just the model where third parties write drivers and never bother to maintain them after 6 months in many cases.
That's because it is so damn hard to measure distance, so sometimes even an approximate distance is not given (but as you imply, distances should be given when known or a reasonable guess is available). That's because the most straightforward way requires you to know the 'extinction' of light towards your particular star. That means, you need to have a measurement of blocking effect of (non-emitting) gas nearby and hope it applies to your (hopefully nearby) object of interest. If you are lucky you'll get a reasonable estimate for distance that is probably within an order of magnitude of the true value, and sometimes you might even get down to a factor of two in uncertainty. And this is just for stuff relatively close in our galaxy. Getting distances elsewhere can be even harder. Disclaimer: IAAFA (I am a former astrophysicist).
I found Ray d'Inverno's Introducing Einstein's Relativity a good place to start and very well presented (a much 'lighter' introduction than others, although goes in less depth, but if you have to start somewhere...).
Here's the Amazon link if you are interested (although your university library may have it, mine did which is where I discovered this gem): http://www.amazon.com/Introducing-Einsteins-Relativity-R-dInverno/dp/0198596863
Good points. Plus the Acer CEO states that people will eschew tablets for Windows 8. Wow, someone missed the clue-train. Like people will wanna pay the Microsoft tax *again* just to get improved file copy and a reorganized desktop? I personally don't think so. Most people don't get excited about Windows like they used to. They still do get excited about stuff that runs on Windows, but these days most the momentum is moving a lot of the cool stuff to the Web or cross-platform. The momentum for consumers is still away from the PC.
20 kB. You clearly are not building applications that are hundreds of thousands of lines with dozens on people working on it. If you were you would be looking at things a little differently (and yes, sure you can do stuff in C++, as I did for a decade, but you are not nearly as productive as you are in Java).
In that case write in Java and compile to native with gcj (which can go everywhere C goes for non-gui stuff). If your requirements include the word 'portability' then Java is usually the hammer you should reach for first.
If you allow your code to divide by zero (or pass any other shitty data from the receiving interfaces to the internals) then you *suck* as a programmer. Always validate your preconditions and handle the issue early. Incidentally Google uses a of languages, including a huge amount of Java (because they need to get stuff done quickly, and can always parallelize to more machines for performance [although well-written Java running in server mode often beats C++ and C, just not FORTRAN, betcha didn't know that]).

Use the rxtx library my friend. It is very good.
Not really (compared with PS3, which is advancing in total sales despite the lead the XBox had), the Kinect is though.

lol, although you sound awfully like the turkeys on the same date a decade before (apologies to our American friends, it is no laughing matter!)

The difference between an "app store" and a "repos" is that they get different points in Scrabble(tm).

Of course, that's if the star is bright enough to do spectroscopy. Most of them are good only for photometry, no?

Shit, even Java optimises bounds-checks away ahead-of-time in most cases.
