Nuclear is inflexible. I think nuclear plant should produce hydrogen during low load period and that cars should run on hydrogen. In Germany, they have stopped using nuclear, the result is more pollution caused by coal. Il think nuclear is the less bad solution until solar solutions are developed.

It looks as if oracle is doing its best to make developers hate them. The problem is that developers of today often become decision makers of tomorrow. Oracle misbehaved about mysql, about java (very bad handling of security issues), about opensource software (open office, open solaris and java) and now even about solaris. I do not know if there are really short term benefits, but I think it is a long term suicide.

As a real people who uses X every days, I can ensure you I have no idea where are the computers that runs the programs that are clients of my display. In fact most of these computers are virtual machines. network transparency has been the first feature of X since many years and the third main Windows program (after Word and putty) I use has been hummingbird exceed, or Xming or reflection X.

Electrolysis is not the more efficient, but hydrogen production by electrolysis is probably the more effective way to store electricity.

Nuclear plants have often excedents of electricity that they burn in resistors in order to avoid overloading the grid. If they could generate hydrogen instead of wasting energy, their efficiency would improve. IMHO nuclear remains the cleaner energy (less harm to our planet) and the safer (http://nextbigfuture.com/2008/03/deaths-per-twh-for-all-energy-sources.html). I think that nuclear and hydrogen should have a good synergy.

Upgrading a system to install windows 8 instead of windows XP is very difficult for unqualified people and will require almost the same installation time than Ubuntu and will probably have more driver issues than ubuntu (ubuntu works better on old hardware than recent windows).

I must admit that it is difficult to find qualified people on ubuntu.

I have already teached math to pupils of 17yo. The most classical theme was the study of a function, but in most of the subjects, the questions are badly phrased and disturbing. My strategy was to teach them how to study a function with only the function as input (without the questions). And when they have understood how to do this, study the different wording of questions and how thy match what they have already understood.

In mathematics, I think the program should first understand the equations, then try to understand the text.

Use crypto and only store the key. A key is small enough to be typed in without OCR. If your data is (correctly) crypted, there is no problem in leaving copies in the wild.

The only solution to protect data is duplication. There is no need for a safe.

For example, I would be really annoyed to lose all my digital pictures. There is a copy on the computer of my father (in another town). It is stored in a crypted (ecryptfs) directory because some pictures are personal. He does not have my password. I have also a backup of its data.

Yes and B gets used to smartphones and in a couple of years may buy a new one. And friends of B who would not buy a smartphone if there wasn't the example of B. I think that one of the reasons of the success of Microsoft (25 years ago) is that it was so easy to copy its softwares. All the stolen phones are like advertising.
