You both make good points. Kids need to learn to be responsible. And my son was reprimanded for making car noises on his way to the lunchroom pretending his lunch box was a steering wheel. The reason? That sort of spontaneity is contagious and the teacher would loose control.... this completely avoids the discipline problem. ha.
.... and there is no money for I.T. because of all the administrators who make more than the teachers, and in the case of our local high school, a football coach / social studies teacher who teaches... weight lifting for 1 hour per day. He makes $78k / year when a teacher with 10 years experience is making $39k / year.
Our school district in South Carolina adopted E-Chalk several years ago. They were going to put the children's assignments online so we could check if the child had done homework, see what was coming up during the week. Nearly all of the teachers didn't put any info in, when pressed by administrators, they put repeating events like "Study and be ready for pop quiz" for the next 183 days.
This year the schools have started using Power Schools which is supposed to have the live gradebook online. Teachers only put grades in around the end of the grading period, so we still can't keep our finger on the pulse. We tried to email our teachers at e-chalk and they some don't check that email, they use their school district email. The school district domain name changed and the email admin wasn't clever enough to forward the old domain's email to the new domain, so again, teachers didn't get email. The problem is an entire organization who doesn't give a poo. Why should they? They get tax dollars and when they don't perform they poor mouth and get even more money.
In so far as actual instruction goes, the teachers are being forced to "teach to the standard", which is code for "teaching the test" by the administration and No Child Left Behind. My child's teacher wishes for parental involvement, yet when I offer to take a long lunch to come speak to my child on the spot if he is getting out of hand, she backs down and says that might damage his self esteem. She (and others) seem to only want to gripe about student's behavior, but really don't want it fixed.
The administration is very keen on "the numbers", especially discipline numbers so they avoid responding to any discipline infractions... the kids are empowered due to lack of discipline and the worst kids act out unchecked in more severe ways. Then the administration has the gall to act surprised when this "good kid" with no prior offenses shows up with a gun or a knife.
Yes, I'm on a rant... the schools have become a culture of their own. The entire system needs a reboot.
About converting the 3d problem into multiple 2d problems by using high gain antennas is abso-freaking-lutly a good solution. I've always pictured an isotropic radiator as a balloon in my head. If you add gain, you squish the balloon in one axis and it expands out all around perpendicular to that axis. Zero signal straight off the tip of the antenna. Ideally a high gain antenna would radiate out 360 in a plane and APs on adjacent floors would not hear each other. They could also make sure the APs were in stacked directly on top of each other on the various floors.
An employer can't ask my age, how many kids I have. My previous employer can't tell them anything about me except the dates I worked, but a new employer/can/ ask for my very optional facebook account?
Me thinks the correct answer is
1)this would violate facebook's ToS. I'm a very law abiding citizen and I won't divulge any proprietary info of yours either.
2)I don't have a facebook because I didn't agree with their ToS.
3)I do not care to work for a company who would ask such a question.
I like what I've read in the article so far. One of the mantras of ham radio is use as little power as possible to communicate. I love that these guys were smart enough to turn off some access points entirely, to reduce receiver sensitivity and transmitter power. It seems they reduced the number of access points to 3... one for each non-overlapping channel. Great!
I gave up on drive time FM radio a few years ago. The loud, annoying, barking "we've bought too much inventory - everything must go" car dealership ads cinched it for me. I now listen to audio books and MP3s on my 30 minute drive to work.
WRT to the TV, we very seldom watch live TV. We DVR everything and watch it the next day. Of late, I have found that some channels are not available on our cable system in HD, so I just download the latest episode (commercial free). We are very close to giving up our cable tv... we have literally 150 channels and nothing on. Now that we've become accustomed to watching TV a day behind thanks to the DVR, downloading from the torrents is no inconvenience at all.
Two cameras? One camera that the cars drive over or under and a 2nd camera perpendicular looking at the side of the same car. Place a barcode on the front of the car... shutter speed would not be so much of an issue as the car would approach the camera for a relatively long period of time. The second camera marks when the car crosses the finish line.
To accept this premise we must accept that a bit error could occur anywhere.. but we as humans tend to accept LSB errors and pretend that MSB errors won't happen.
White as 255 or white as 254 sure, who would care... but the hardware noise could introduce an error at ANY bit... How do you feel about white as 127?

Where can you find a flashlight with a USB cable?

In another classroom, droves of students learned to operate the UI of a dead tree even faster than our iPad control group learned to use it's apps.
When I learned morse code, I began to hear whole words. This is the same thing.
