Time to ditch the front door key? Nest's new wireless smart lock is surprisingly convenient

The Lock Must Handshake with Google?

Besides all the other problems previously mentioned, what happens when your ISP is down, or in other words telecommunications is no longer available? I need a good new home security and lock system. But nope. Even if it is something as good as 99.999 % of the time, what back in telephone engineering days was called the 5 nine's, if other links in the chain do not meet your standards, you can expect to be locked out.

What the @#$%&!? Microsoft bans nudity, swearing in Skype, emails, Office 365 docs

Skype is Broken

Once, long ago, I loved that Skype point to point encrypted. Then M$ bought it, presumably because the United States government offered a large reward to an entity that managed to break Skype encryption. Some months later I noticed Skype's once magical echo cancelling had been broken, so that now one or both parties must use earphones. The new poor performance is consistent with my theory that Skype latency increased beyond it's codec echo cancelling capacity due to a new requirement that audio packets no longer are allowed to route point to point but must transverse a M$ server. Since at my location there is probably no local M$ server, Skype has turned into sh*t. Poo on them. I'll poke Silk into my own asterisk server.

Much of this article fails to acknowledge the difference between radio waves, electro-magnetic waves (EM), and magnetic fields such as what you get from being near a power line. Cell phone signals are EM of far higher frequency, classified as UHF or higher (800 MHz to 3 GHz). Motion of electrons, in other words current flow, creates a magnetic field. Magnetic fields are created by power lines, and any electricity conductor that is exposed to EM waves. Yes, radio waves induce a current in any conductor. That is how an antenna works. Your body is a conductor and therefore can act as an antenna.

Any current, thus any magnetic EM created magnetic field will penetrate your body to some extent. The question is, how deep? There is an effect called Skin Effect. As the frequency goes up, current flow will more and more be on the surface of the conductor. In other words, a cellular signal does not create a magnetic field deep into your body. At the upper range of cellular, most of the current flow will be in the surface one millimetre. http://chemandy.com/calculators/skin-effect-calculator.htm The power grid works at 50-60 Hz. The low frequency was chosen in part to reduce skin effect.

The meter used in this study, an EMDEX Lite is unable to measure any frequency above 1 KHz.

Big fail! http://www.enertech.net/html/EMDEXLiteSpecs.html

So I'm calling this article, and the study prompting your article deeply flawed. Look at the comments following this study.

Animal studies? That will be interesting... I will look for that.
