Doesn't this indicate a serious lack of a reasonable network design on AT&T's part? There are technologies available (SONET rings, etc) which prevent cuts like this from causing outages by setting up redundant paths. I worked as an engineer in telecom for several years, and it was my belief that all the major carriers deployed essentially bulletproof networks, and made good use of the available technology (and this was 12 years ago!). I guess I was wrong!
The trick is to build an array of light sensitive chips that each record small parts of a larger image and place them at the focal plane of a large multiple-lens system.
Oh, you mean a digital camera? Definitely sounds tricky...
How does that stop phishers from sending spoof paypal emails, and people believing them? Even if Paypal does their best to inform people of a change like this, you will always have that small percentage of people who see the spoofed email and believe it, which gives the phishers all the incentive they need to continue. (Especially considering that small percentage is probably the same set of people that buy into the phishing emails currently) Should this proposal succeed, even with just yahoo/google/hotmail, that should eliminate a majority of the recipients of these emails, which will definitely reduce the incentive for the phishers.
2) People create a lot of greenhouse gases, and pump them directly into the atmosphere. This comes by way of car exhaust, factory air pollution, power plants, and a host of other things. Automobile pollution is probably the single biggest cause though.
Actually, transportation fuels (which car exhaust is a subset of) are only the #3 contributor of greenhouse gases behind industrial emissions (#2) and power plant emissions (#1). Coal power plants are by far the worst emitters of greenhouse gases (among other nasty stuff, like radioactive Uranium, Thorium, and Potassium-40).
While cars are definitely part of the problem, I think the world needs to first focus on the biggest conributors, and start realizing that we need nuclear power plants. This is a big problem in the US, where public opinion is fairly galvanized against going nuclear.
If the telescope was on the north or south pole, that is correct... the camera would be the only thing you would need to rotate. At all other latitudes, correcting for the rotation of the earth would require moving the entire telescope on the same axis, which is not possible since it can only point straight up. This telescope would essentially limit you to a very short exposure time, while the object you are viewing is directly overhead.
