Yes, but plants and sub-stations don't need to shop on e-Bay or check their Facebook status now do they?
If they need to be connected to a network, make it a private network and most of these issues go away.
There is no sane reason that these networks and these facilities should not be air-gapped from the internet at large. There are ways around the air-gap (stuxnet), but even these are trivial to prevent by not allowing random USB keys from outside by gluing the port closed and/or securing the hardware properly, and/or beating anyone stupid enough to do this with a stick.
It's not nuclear science or anything, it's just common sense.
If you want to give these kids a solid foundation to build on that will instill good habits and understanding of how computers work - C.
Java runs on top of an engine written in C - same with Python. They're great for doing that they do which is providing a massive library to take out all the menial tasks, but those menial tasks are the ones that teach people how everything works in the first place. How do they become a menial task if no one ever learned they were there?
Do we teach calculus without first teaching numbers and then general addition, subtraction, multiplication, division, etc etc etc
I have spent years beating the bad habits of Java out of programmers. Garbage collection is all nice and wonderful but it prevents programmers from having to think about memory at all. Taking that Java programmer and trying to get them to write even simple C/C++ code or even something as basic as assembler is damn hard! Everything they have learned has to be re-grounded. It's like boot camp - break them down to so they can be built up into something useful.
It's easy to teach someone who knows C how to write C++, Java, Python, or the zillion of other languages out there.
My gmail account has had 2 spams make it to my inbox in the last 6 months (probably longer) of the 20-50 spams a day the account receives. I have never published the address and have only even given it out to friends and family but it has received spam since the day I opened it. I also don't have any other email addresses forward to it. Very effective for me.
All my servers have SSH sitting on a high port and have never had SSH attacks on them. In the one case where someone found the port, their bot attempted to use the port to proxy a web page.
On port 22 I run a program that firewalls out anyone who creates a full TCP connection:)
I've found that Synergy doesn't work correctly with the mouse look in WoW. It just spins the view around really fast and eventually settles on looking straight up - quite annoying. Keys & clicking on things work just find though.
Most of the ISPs joined onto PIPE Networks in Australia have free traffic between them. It comes up in your traffic usage but under a different heading that doesn't contribute to the monthly limit.
This makes all traffic within the ISP and most of Australia free, but everything else outside that network counts.

All well and good for prosecution immunity, but why would anyone keep an open access point these days?
I live on a main street with many business people walking past with their WiFi enabled devices. If I didn't have my access point locked down hard they'd blow my bandwidth limit inside a few days.
Yes, your computer will resend it but due to the sliding window protocol http://en.wikipedia.org/wiki/Sliding_window it will also reduce the speed at which it is sending. By dropping a packet TCP will detect congestion and reduce the size of the window. For every dropped frame it will reduce the window by a factor of 2. Each time an entire window is sent without a drop, it increases the size of the window by one.
So it quickly drops down to below the available bandwidth then slowly grows the speed up to it.
This normally happens auto-magically between the two ends of a TCP connection to grow the connection to the capacity of the smallest link in the chain as a result of random drop or FIFO queues. By tracking each flow and their window management, the window size and thus speed of the flow can be controlled by any hop in the chain.

Someone should patent the idea of such a colossal screw up .. they'd make millions!
On a more serious note, perhaps this might shake things up enough for some real patent reform.
Hell might freeze over too.
I hate users who think every address has to have a www at the start. :(
webmail.example.com != www.webmail.example.com
