One tip I can give you is to do a vulnerability pentest on a copy of your system or before you launch. http://www.websecurify.com/ is a greyhat tool specifically built do a thorough testing (really, it's impressive software) of your site and it's extremely easy to use.
Academics and students would love to contribute to Wikipedia, but it doesn't help if the whole campus IP range is blocked for editing for several years. =(
And Wikipedia is a good reference nowadays. Even Randy Paush claimed this four years ago in his famous 'Last Lecture'
Not really.. The graphene isn't used for transistors, but CNT is (carbonnanotubes: folded graphene). It is very unlikely that CNT will ever be used for scaling in transistors (16 nm) because of the k vector and phonon effects. Copper just scales linearly with size, but CNT gains too much resistance (k vector, phonons, edge/connect effects) at the lengths where this can be used in future transistors.
Getting the CNT or graphene on SiOx isn't such a problem though. If you apply the right fields you can bend the material easily enough. Though the material properties are extremely difficult to control cost-efficiently for mass production (millions of exactly the same transistors for processor components)
In research the 'scotch tape technique' is still used as the easiest method to generate graphene and graphite sheets. The scientific term is exfoliation of HOPG (Highly Orderdered Pyrolitic Graphite) and basically comes down to pulling apart two scotch tapes from each other and/or placing the tape on a SiO layer. Other methods include bottom-up synthesis on metals (difficult to fix the amount of layers) or SiC wafers (expensive, difficult to control). For flexible displays SAMSUNG is currently just printing large 30 inch sheets of graphene (with a support polymer).
If President Obama can recieve a Nobel prize for things he promised to do, within a year of when he started, then Linus Turvalds, who helped built the crucial basis for technology that will last as long as computers exist, should've gotten a prize almost twenty years ago.
