"The garage-door opener frequency at issue -- 390 megahertz -- has belonged to the military since around 1950. Openers have legally operated at that frequency since at least the early 1980s, Karasek said. U.S. law allows low-power electronic devices to operate on military frequencies if they don't cause interference. It was a good frequency for garage-door openers because transmissions can penetrate the doors."
The article goes on to say the military is trying to make more efficent use of their current spectrum. So this problem is caused my manufacturers of the door openers, and not the military.
I agree 100% with this. My best profs in college taught the old fashoned way, an over head projector, writing the notes as they went along, based off the hand written copys they prepared for themselves. this way if a student had a question they could divert from the lesson plan to answer it. the teachers who used powerpoint were useless. ever have a class where a "coordinator" makes up the ppt slides to use for all 4 sections of the class, yet he only teaches one. the other 3 teachers have to figure out what is going on, then try and convey that info to the students. So many times in my circuits class my prof was like "um im not 100% sure why he put that in there, ill have to find out for next class"
my best math teacher, and signals teacher were big fans of doing stuff by hand. and in signals i got used to having Maple do algebra simplifications for me (no use in doing 5 and 6 term PFE by hand) and now i have gotten slightly rusty at it.
On the other hand computers in labs are great. using a computer to interact with a microprocessor, but then again it is kinda necessary in that situtation.
It would be cool if teachers could recreate colonization and wars using some RTS game. imagine being able to see the wars happen in real-time? maybe after class let the students try their hand at being a general and commanding the troops, see if they are any better than the real life ones. thats just one idea for bringing computers into classrooms
Ummm, you seem very very paranoid about this remote control warfare. But what you fail to realize there is nothing to stop militaries from developing remote vechicals right now, that use traditional controls. In fact i remember reading stories on slashdot about remote control development and training...
Yeah, the lucky drunks!
ever see those pint glasses with a buldge near the top? it looks like someone put a dougnt around a glass when making the mold.
it holds 20 oz instead of 16oz.
my buddy told me they were called irish pints
No, according to his logic, a valid conclusion to draw would be that Microsoft is very successful due to the sheer number of users paying for their software.
he didn't say it was the best, just that it was successful. hmmm, seems similar to how windows may not be the best os, but it is pretty successful.

From the article YOU linked too.
