It’s not only fun and cool but the more we open ourselves to the outside world, the more we become an easily exploitable target for others. You think, you don’t have anything to hide or nobody would want to “hack” you? Well, you might wanna think again.

“Oh, Amazon listens, too?” – Alexa and your privacy

It was this years Super Bowl, Eagles vs. Patriots, and I invited some friends over to watch the game together.

Well, we’ll get to that, but first let me ask you something: Did you spend time to get some kind of insurance? Maybe a fire insurance for your house or an extended health insurance that covers your teeth? You didn’t do that because you want your house to burn down or your teeth to fall out, you did it to be prepared if the worst case happened. You could ask the same questions: Why would somebody light a fire to burn your home down? Why would you not pay attention to burning candles, yet everyone understands that these things could happen. There’s a slight chance that it might hit you, so you get insurance.
