And first most important greenhouse gas is water vapor. Regardless of the truth of AGW, it is not immediately obvious that smog in cities indicates or leads to a significant effect in the atmosphere. I believe in AGW but let's not claim the climate science is easy to understand or obvious. This is why I get angry when AGWers equate those that disbelieve in AGW with creationists; the principles behind evolution are much easier and more intuitive to understand than climate science is.
The government isn't likely to snap and go postal with me as an innocent bystander.
Oh, how utterly wrong you are. Why not ask the 22-year old man being sent to prison over this? He's an innocent bystander to.
Running C++ in a browser app? Can't see that one blowing up in anyone's face.
Of course, the big probale is you need a language that can be made to run in a very secure sandbox. Java, python, and related languages could be made to do so with some work. They run on VM's or have an interpreter. But C++? If you're talking about creating a new implementation that runs in an interpreted/virtualized/sandboxed environment and has built-in memory management thrown in, then that might be a possibility. But then again, why would you want to do that when there are so many other ones out there.
It is much easier to suggest solutions when you know nothing about the problem.
