Dear Mr. Torvalds, What is your opinion on manual voting vs electronic voting in the context on national elections? Can electronic voting be safe when most people participating in these elections (including politicians, businessmen & reporters) do not understand the technology behind it and the masses follow what politicians, businessmen & reporters say?

You could download a 30 day free demo of Wolfram Mathematica and play with its GPU support. They have done a good job of automating a big part of the complex GPU programming process. http://www.wolfram.com/products/cuda-opencl-programming-mathematica.html

People against this idea normally argue that your employer could ask for your unique voting key to verify that you voted in a particular way.

This can be avoided this way:

1) When you vote, you would write down you own voting key by hand in a piece of paper of your own.

2) In a web page (or CD) you should be able to see the voting keys of all the voters of any voting center.

3) If your employer asks for your voting key, you could give them a diifferent voting key of your same voting center which point to a vote of the political preference of your employer.
