Moreover, what the person doesn't seem to understand is that if the kids have physical access to the computer, particularly when there is nobody around (ie: at home), any kind of lock will not work. Physical access to a machine has always, and will always, trump any security measures or restrictions you try and apply.
How often do we hear about root exploits? It only takes one of those for a kid to get root on his machine, at which point he can remove whatever you have put on his machine and tell all his friends how to do it.
Then some goofball administrator would slap them all down because they 'broke the rules'. Shouldn't lateral thinking and curiosity be encouraged? Are you willing to deal with that can of worms? Trying to explain to administrators that there are rules but that the ones who break them shouldn't be punished because its still educational would sure be a lot of fun.
Good luck with that.:)
I agree, there is more than enough incoming solar radiation to take care of all our energy needs. There would still be a place for nuclear generators (ie: submarines, aircraft carriers, etc...) but for the most part the household, commercial and industrial power loads could be taken care of. These account for most of our energy needs so all we would need to figure out is how to deal with vehicles.
Solar airplanes have been extensively developed, electric cars could be plugged into a solar grid and the rest could be taken care of by small nuclear generators supplemented by solar and wind systems. Come on, this isn't rocket sciences...
Oh, yeah, rockets. We'd have to figure something out for those too... Magnetic launch system anyone? http://spacemonitor.blogspot.com/2007/03/magnetic-launch-system.html
Slightly under 3 minutes. Assuming 485 knots, which is the usual cruising speed for a 747-300. So unless you can scramble fighters and shoot it down in under 3 minutes, you're fucked. Moreover, even if you manage to shoot it down it's going to CRASH into a populated area. What's worse? Losing the sparsely populated White House or an entire apartment building (easily 300+ people)?
Most of the 1421 theory revolves around a map that seems to detail North America in some fashion. However, that map was proven inaccurate as the mapping around the area it was purported to come from was WORSE than the mapping of North American, which makes no cartographic sense.
People have better maps of where they come from and worse maps of where they just explored. Makes sense. Until somebody can find more proof to back up the 1421 claim, it is an undecidable as to its veracity.
To an outside observer (read: alien), wouldn't we never actually die? We'd get asymptotically close to dying, but never go through with the whole 'dying' part. Kind of like a goth-kid that gets more emo by the second.
You have it backwards. Your public key is used to encrypt messages that are being sent TO you, which you can then only decrypt with your master key.
The idea is that you (Alice) would send your message encrypted with Bob's public key to Bob. Since only Bob has his own master key (since it doesn't get posted to the server), then only Bob can decrypt it. Bob would then reply to you by encrypting his message with your public key. And so on.

But lack of seals is good for cod. screw those seals and their radial seal agenda!
