Damn. That should have read: "more of the simple lighting devices". Because of their limited lifespan, you'll quite simply need an increased number. Not to forget that the energy needs to produce LEDs have gone way down.

Right. And you shouldn't neglect the increased energy needed to manufacture more

Erm, an incadescent bulb also isn't a point source of light. I'm also not quite sure why you'd need sharply defined shadows in a household

You do realize that the colour spectrum of LEDs is a solved problem, right? And that there's more than one type of LED?

The energy "consumed" in a typical household for lighting amounts to approximately 10% of total energy usage.

German households consumed 609 billion kWh in 2012. Which means that using LEDs everywhere would reduce lighting usage by 75% - resulting in a total reduction by ~46 billion kWh.

This amount of energy amounts averagely to two(2) 2,6 MW power plants. That's the numbers for Germany. Of course, in 2012 we already had LEDs and stuff, so the real number would be lower. Maybe 50%? But that would stll get rid of one whole power plant. I dare say that is pretty significant.

While we were forced to use DPI in order to catch people torrenting movies (our university threatened to pull the plug otherwise!), we also used it to catch the inevitable Worm infections or Botnets.

Such computers were isolated from the rest of the net and (almost) all HTTP traffic was redirected (save for traffic to know antivirus software providers) to a page which stated that their computed was infected with Zeus, Conficker or whatever else is floating around there. And that they were to clean up their PCs and that we also recommended a complete wipe. They then had to type in "Yes, I understand" and were given a 24 hour grace period. If, after that time period, their PC was still infected they were off the net until they proved a complete reinstall to us.

Since every part of our body is replaced on a regular basis by our own cells, we're always not the "same" person at some point in time. The questio should rather be: "Do we view such nanotech as the equivalent to the already existing biological replacements?"

Nonsense. I certainly didn't create cowards!

What kind of stuff are you smoking for regarding "number of pages written" as a valid sign of quality?

When I'm grading my students, I take the number of pages as a very rough indicator on how much time they spent (with all other stuff like text size, paragraphs,... being equal). Doesn't mean, however, that this quantity equals quality.

And even if he did tell them the criteria before - that still doesn't make it a good criteria. And blindly following instructions is never a good idea.

What the fuck! We don't have those laws around here and the judge will beat you around with a clue-by-four if you suggest that you were allowed to escalate the situation by using lethal force needlessly.

Lead-acid batteries are quite easily recycled. Granted, you have to take care due to the lead - then again, the other batteries have similar problems. On the other hand, they're quite simple: Lead, sulfuric acid and that's about it. No exotic materials.

Those are locked-down consoles. Might be a trifle difficult to install a direct competitor on such a device. You're pretty naive if you think that AMD can simply provide such tools against the wishes of the creators of the console.

Not to mention that I'd be wary because even if you got it to run, you as a developer might simply be hit by the banhammer for using an inofficial API.

Right. Cross platform would be important, especially if the API appeared on the next-gen consoles.

However, I can't really see Microsoft implementing this API on their console. And I don't think Sony will do that either.

And then there's the fact that a game developer now needs to implement two APIs - and if "Mantle" is actually closer to the hardware then there won't be much portability between the two. Which makes this somewhat dead in the water.

I've heard of those drive-by-wire systems! What an ingenuous way to steer a military submarine!
