See Snopes for examples that attribute the same story to Tesla and Edison, as well as anonymous engineers, mechanics, and plumbers.
Also, pianos also have dampers (felt pads that lower onto the strings when the key is released) and petals, which control the action of the dampers. Furthermore, the vibration of strings on the piano can effect other string especially with the damper petal down. So a bit more complicated than you make out.
In addition, we require all Class B signal booster installations to be registered in an FCC signal booster registration database. Thus, in the event a Class B signal booster causes interference, the operator of the device can be located and asked to shut down the interfering device.
This taps into a basic human driver. Scarcity makes people feel special, and working hard to get something makes people perceive the value is greater.
Of course, Google needs developers to embrace Google Glass to be successful. The more the better. But by making it exclusive people will value it more. Such are the problems of a digital society, where almost all that is left is artificial scarcity.
And, they are controlled remotely, which means that they can be jammed. However, the ability to jam communications also effects piloted aircraft. Looking into the future, it is clear that UAVs will continue to develop autonomous technology, so they can can take appropriate action when they loose communications with remote pilots.
Ultimately, a goal of the UAV program is autonomous vehicles, that have objectives specified by humans but carry out those objectives independently.
There is no denying these folks are smart. But they are not highly educated. I also question the level of investment. Apple, Microsoft and Facebook started in dorm rooms and garages.
The reality is that while education is necessary to develop the underlying technology (the integrated circuit and CPU, high density storage, computer networks and the internet, touch screens, etc), it almost seems like education is unnecessary, or even an impediment to actually creating popular consumer products.
Bill Gates, Steve Jobs, Mark Zuckerberg, and many others would beg to disagree.
Changing batteries has also been available for laptops forever. It is totally inconvenient. How much time per day do you spend managing your batteries?
Why are you watching movies on your tablet? Don't you have a nice big screen? Wouldn't a study pillow be easier?
And finally...real geeks don't exercise.
Where to start complaining? Don't roll your own http server. You probably don't understand what you are doing, and you will get weird results. Using Windows as a platform for a java web server is pretty silly. The author incorrectly assumes that because the
