Slashdot videos: Now with more Slashdot!
I suggest SSHblack. It automatically updates IPTables and it's a python script. It allows a fixed number of connection attempts, then just drops the packets. After a period of time it can remove the ban, improving performance. This also prevents the aforementioned problem of sitting down to a virused comp, and if you're travelling, you won't have issues either =)
Extracting thorium from the ground is harder than for uranium, and the enrichment process is more difficult and costly.
Sorry, there is only one naturally occurring isotope of Thorium, therefore there is no enrichment to do.
It will however be necessary to kick start a reactor running pure thorium with something else. You can't just build up a mountain of the stuff and get a reaction going. I think that Thorium is great from a PR perspective because it's not Uranium! People are so scared of what they can't see it's crazy.
Nuclear power isn't as complicated as one might think. It all comes down to something that can boil water, to drive a turbine....pretty similar to what you do when you drive to work.
That is the waste of human knowledge with time. Failing to secure the knowledge of the world's past is criminal. Digital copies of all published work should exist, in a single location, for the preservation of knowledge.
I agree that rightholders should be able to control access to their content. Perhaps a payment system can be worked into the equation. The cost should be considerably less than print works, simply because digital data doesn't require printing, etc, etc... Orphan works should, however, remain part of our history, and should be accessible. Furthermore, any work in the public domain should be available.
So far, I've bought three books for which excerpts were available. They were scientific works, which I would not have considered buying unless I had seen a preview, to ensure they had the relevant data I needed. I then donated those books to my library.
Win, win, win, for everybody. Vive le googlebooks...
