You can still exclude people with HIV just not every group that might have incidence of it higher than some arbitrary percentage. If you tell people with HIV not to donate, 99.9% of them will refrain. The .1% that don't refrain would have donated no matter the restriction. What about people who have HIV and don't…

You cannot donate if you have Sickle Cell Anemia, either. Since people descended from sub-saharan Africa have the highest incidence of this disease, should we exclude all people of African descent?

People lie about the sex they have to everyone, including themselves. Rules like this don't necessarily make anyone safer. Gay male blood donors are accepted in most Western countries but not here. They aren't having trouble screening the donated blood for Hepatitis and HIV prior to use. Which are the better odds…

Aren't organ donors (of the type discussed here) dead? So who cares if they harvest everything and use less or none?

Maybe, but not at all effective.

The fan itself is part of the inefficiency. A heat source at the floor will rise and create convection; it puts the heat first in the area of the home people tend to be in, and the vents are placed in the positions most strategic to heating (one would hope, at any rate.) While it may be possible to have people up on…

It's not wasted until the Chinese hack into our computers, steal the plans, and build their own.

The function of a light bulb is light, not heat. While it may be true that 100% of the energy going into the bulb comes out as either light or heat, your light fixtures and their placement are designed to maximize light only. A ceiling fixture will just add more heat near your ceiling, which isn't terribly useful. …

"Vivid" is also a common word in the english language and not a proper noun like "Pepsi", "Kleenex", and "Xerox". (IANAL) Part of the legal calculus here will be determining if the two companies are in the same market and thus using the same word would create customer confusion.

Depends. They can work at night when everyone else is asleep. They work on weekends and holidays and they work as long as they are charged. The have no wages so you only pay a sales tax on them and then write off the depreciation over their lifespan.

Fingerprint reader for the win. Avoids Apple's patent on unlock methods and avoids Google's current pattern swipe thingy that leaves a greasy tattle-tail smear on the screen. You only need to remember to bring your fingers along. Cool beans!

The minute someone figures out how to suppress the gene through drugs, it will show up on the black market for sale and we'll all discover first hand what the side effects are of the medication and/or the uncontrolled growth of muscle.

Well, we would perhaps see a reduction of trucks driving between major metros rather than just within. Why truck goods between Phoenix and Los Angeles, for example?

Sorry... meant "iPhone 4". It would be an example of Apple not supporting older versions with the new software.

Use taxes should also be levied in the form of weight-based vehicle registration fees. Right now, the average car owner subsidizes the trucking industry by paying more than their share of road repair costs. If trucks were charged based on the damage they do, we'd probably see more trains.

"Well Done Filet Mignon"... ugh. Well done? What a waste.

Yes. The more voters that are affected, the more likely these laws will spring up.

IOS devices are uniform. There is a single OS/Hardware manufacturer and they support all their devices. Android is just a free operating system that hardware manufacturers may choose to use and may alter from standard. As long as they can alter them from standard, there is no way they can be supported by the OS…

My phone (Nexus One) will be two in a few months. Are you saying it's going to spontaneously die prior to its two year mark?

The guy has a fractured skull as a result of his injury. Not at all funny or ridiculous.
