Comment Not likely. (Score 2) 182

I know a CEO has to say crap like that, but it's just so ... over the top. I know classrooms are the holy grail for corporations, because it's all about the kids after all and money should be no object to a quality education, but damn. I'm surprised he didn't launch into how VR technology could drastically reduce the spread of the severe respiratory disease that is currently sweeping through schools in some parts of the country. Why is this on /.? He needs to stick to where they will probably really hit the jackpot, porn.

Comment Good intentions vs free time (Score 4, Insightful) 182

I have signed up for 3 of these from Coursera. I've completed two and dumped one. They do involve a fair amount to time to get through, depending on how familiar you are with the subject matter to start with. I'm guessing most of the people who do this are people who sometimes think about going back to college but aren't quite willing to dump an existing career that pays the bills but perhaps leaves them not completely satisfied. I guess the question I would have is how important is it to these places that people finish their courses? Given that the price right now is $0, maybe they could charge a nominal free (like $20) to sign up, refundable if the course is completed.

Maybe that's why they're shutting it down. Nothing is really free, someone has to pay for your free miles or cashback, and in this case it would be Amazon through merchant fees to the credit card companies. If enough people did this, they'd be losing money more quickly than they could make it.

They dropped the transmit power when they switched to digital. Theoretically, this was OK because digital receivers can obtain a usable signal from a much lower input power. However in reality, the effective footprint of OTA channels was definitely reduced. During the transition the maximum output power was reduced from 100kW to 45kW, even though digital transmission is only 30% more efficient.
