Why do you keep posting that?
Once they are finished with their nerd cleansing, they can build a new Slashdot. A sexier Slashdot. A Slashdot the kids can dance to.

Solar power uses rare metals whose use could be just as bad as fossil fuels.
Huh? Yes, certain types of thin-film cells use rare and toxic metals. But what about plain old silicon cells, which make up a majority of the PV market? They consist of:
- silicon (extremely abundant and non-toxic)
- aluminum for the contacts
- tiny amounts of boron and phosphorus as dopants.
I know you're joking, but how can an ablative process be used to deposit material? They're kinda the opposite of each other.
I highly recommend a program called Celestia. It not only shows star charts, but it allows you to explore the local universe in 3D. A similar program is Space Engine, although I don't think it's as polished and complete yet (although it may have a better renderer).
Purposely. Purposefully means something else.
Teflon is not, to my knowledge, very elastic. It's essentially a rigid plastic. Condoms need to be able to stretch and experience, ahem, rather extreme dynamic loads during use. They need to be quite stretchy so that they don't tear.
You can already do this using pseudo-random number generators. While pseudo-random numbers may not be random enough for certain scientific computation purposes, they are more than adequate for gaming. There seems to be a common misconception that computers are incapable of producing randomness. Pseudo-random number-generating algorithms, seeded with simple things like the system time and keyboard events, are good enough for 99% of common everyday computing tasks.
The advantage of this 'approximate computing' is that the hardware may be able to use less power. The randomness is a drawback, not a virtue.
JPEG is not a scaling algorithm. It is a (lossy) image compression format. By 'compression', I mean it allows you to compress the file size (measured in bytes) -- not the image dimensions (measured in pixels). It has nothing to do, really, with resizing an image.
Scaling algorithms are things like point sampling, bilinear interpolation, bicubic interpolation, etc.
Decimal: 1 bit can be one of 10 different values, so five times more information is present in a single bit.
No, that's not what a bit is. 'Bit' is short for 'binary digit'. A bit can, by definition, only hold one of two possible states. It is a fundamental unit of information. A decimal digit comprises multiple bits. Somewhere between 3 and 4 bits per decimal digit.
Most people don't have the faintest clue how technology works. It might as well be magic to them. Therefore, when people see things like the Terminator franchise, Battlestar Galactica, that terrible I, Robot movie, etc., the concept of a robot uprising seems plausible to them.
I'd rather be blind than have a bullet to the head.
Funny, I'd rather the opposite.
Poe's law applies here. That discussion thread -- they're not serious, are they? It must be a subtle troll, no?
If you don't mind waiting a long time, perhaps you could use solar sails? Although, I'd guess that solar sails are only useful for providing radial acceleration (i.e. away from the sun), so this might not be useful if you're mining the stuff beyond the earth's orbit and are trying to bring it back home. And I doubt there's an analogue to "tacking" in the vacuum of space.
An alternative is to use solar cells to provide electrical power, and use the copper itself as propellant in some sort of high-efficiency ion engine or accelerator. You'd be cannibalizing your payload to use as reaction mass. Copper probably isn't an ideal propellant in such a system, but if you have billions of tons of it, you probably don't mind wasting a significant fraction of it.
A third option could be nuclear pulse propulsion. Something like the orion project?
