1) It's not really for the sake of being "Green". I don't consider longer battery life on my phone to be a "green" attribute.
2) Digital calulations are already estimations (try storing 1/3 in a float). There really is a tolerable threshold, and it does vary by the application. Software engineers already need to understand, and accept this uncertainty. If you could hint to the compiler that you were interested in this Lat Lon coordinate to 8 decimal places, but you weren't interested in the intensity of this floating point image to more than 2 decimal places, then you could allow your processor to speed up, and be more efficient. Another way you could use a hint is that I don't care if 1% of these pixels are completely wrong.

Comment: Only give access to a great big wiki site. (Score 1) 330

Let them edit it throughout the semester, and then only give access to that site (hosted on a machine on a LAN, not connected to the internet). Then everyone would have the same information base, and they could search for information. You could even keep the information alive through semesters. Make sure it's read only during the test. And you can go through it quickly after writing the test to make sure no information is too helpful.

Even better, or also, you could host a stack exchange like service too, that people can record and exchange information for the projects they do during the semester. Teaching is the best way to learn, after all...

I think most cells in the body are replaced on a regular basis. So are how old are you? By your standard, you are only a couple months old. Bodies are constantly copying cells, and if we could survive like the brooms in fantasia after being chopped into little bits, then I would say that's pretty close to asexual reproduction.

I'd add that this approach has two benefits.
1) You can fill your resume with applicable experience, and be able to answer the question "What were you doing the last six months?"
2) Meeting and working with other software engineers can make a big difference in finding a good job. It's not what you know, it's who you know (and what they think of you).

You might see the warned car beeping, but it might just do things you won't notice.

For example, in that two seconds where it thinks there might be a problem, it could increase the gain on the brakes, and reduce the gain on acceleration. So if you are accelerating towards a stopping vehicle, it will not accelerate as fast, and if you start to brake, it could brake harder. Alternatively, there could be subtle gains to be had as well. In a hybrid vehicle, it might prepare to regenerate the batteries, or if you are in cruise control it could change the speed. There are a lot of complicated things happening under the hood of a modern automobile, and you'd be surprised how little it could take in a lot of cases to reduce fatalities.

My common sense would say that if the user already gave up control of their PC to the botnet, why should they have any say in keeping the feds from removing the bot? The reason the feds are interesting is (I'm assuming) because the botnet caused harm to others. Just remove the bot, if there are consequences, and they know what they are, then it's their own fault.

But, the federal government is held to a higher standard aren't they?
