Heat is not infrared photons. Heat is random motion of microscopic particles. Infrared photons are electromagnetic radiation, just like visible light.
The confusion comes from the fact that heat can be transferred via radiated emission from one body to another. If you shine light on something, it will get hotter. Hot objects emit light, with peak wavelength dependent on the temperature. For temperatures less than red-hot, the object will emit mostly infrared.
It's probably possible to capture the infrared light emitted from a hot object and turn that into electricity with some kind of photovoltaic, but your photovoltaic would have to be colder than the hot object, or else the photovoltaic will emit its own infrared and lose energy. So you end up needing a temperature gradient; you'd probably be much better off with a Peltier.
Computer science and software engineering are two different things. What is now called CS really needs to be separated into software engineering and pure CS. The CS people really don't care about software dev cycles and databases, and the SE people don't care much about Turing machines and information theory. The problem is that the CS department is clogged with students who just want to get into the industry, and the professors want to teach a more theoretical approach to CS.
Should I really need to evaluate the ethics of of every company I purchase from?
You shouldn't need to, but you should nevertheless evaluate the ethics of every company you purchase from.
Yes, but then if a recount is done, and the receipt states that you voted for candidate X, and the system shows that you voted for candidate Y, you have undeniable proof of fraud.
No more of this nebulous FUD currently surrounding the voting machines. You would have cold hard evidence.
I don't know what you are talking about. If something becomes a science, it wasn't a philosophy? You seem to be forgetting that science used to be (and maybe still is) a field of philosophy. It was philosophers who came up with the concept of an atom. And it's philosophers who came up with the concept of strings.
You might argue against it from an ethical standpoint, but there's nothing irrational about it. Why should we allow North Korea or Iran to have nukes? To be fair? Fairness is irrelevant. We are powerful and we want to stay powerful and that means we want others to stay weak.
From the LHC design report, the proton energy is 7000 GeV before collision. This is small potatoes compared to some of the ultra high energy cosmic rays. We often get particles of 10^18 eV, and some as high as 10^20 eV. In other words, the LHC is not going to destroy the Earth.
From others' posts, I can tell that I hold a minority opinion, but video game crime has gotten way out of hand. We should charge anyone who frags another player in a deathmatch with homicide, because there's really no difference between violence in the game, and in real life.
Most vigilante animal rights activists won't go as far as killing people though. They might commit arson or property damage, but how often do they kill people?
I have to agree with the window model sucking. I tend to maximize all my windows anyway and alt-tab between them. I only window them when I need to copy and paste something where the copy and paste feature doesn't work for some reason.
Especially annoying are those apps that spew multiple toolbars and palettes in several child windows which constantly get in the way (as in most paint programs).

Won't work. Each pixel would have to travel in a different mode along the fiber or they'd all be blurred together, and you control so many modes.
Yes, but give me a reasonably good default option so I don't need to choose if I don't want to.

That's why you hack your phone. Then it can be useful for you.
There's lots of timewasters for social-skill deprived undergrads - D&D, WoW, etc. D&D is a social activity. TV is not.

The whole problem with this argument is that it is the worst execs are overpaid as much as the best. http://www.dolmatconnell.com/resources/2006DCPTech 100Study.pdf

Because might makes right.

You are missing the value of tiny. Tiny means you can carry it with you. Everywhere.

When I write my ultimate badmalspyware, I'm going to blackmail the world for ONE MILLION DOLLARS. I'll be laughing at the schmo who only got $430.

Want to get this law removed? Everybody, start accusing your lawmakers of sexual misconduct.
Yeah. It's like they have an unwritten commandment: thou shalt not play God.
