Wireless

Some people ask me why, being a software developer, I have cables rather than wireless in my home. Here’s one reason:
“A doctor I know set up a local Wi-Fi network in his house so he and his wife could work on their computers without running network cables all over. When he turned on the transmitter for the Wi-Fi, his wife immediately developed arrhythmia. He is a cardiologist so he knows for sure what it was. He turned off the Wi-Fi and her arrhythmia stopped. This increased ill effect of digital signals is most likely due to the sharp edge of the square wave where the differential of the change of the signal approaches infinity.”

Creepy app uses Twitter and Flickr data to track anyone on a map

When you post a photo online — especially from a phone with a built-in camera — you’re likely sharing more than the picture itself. The same is true for updates you post on Twitter. Location data is commonly included, and crafty types can do all kinds of creepy things with that information.
