Our brains are wired such that we automatically cancel out things that are not changing around us, in a process called adaptation. I really like this article because it not only gives a lot of interesting information about the brain, but it also hooks the reader effectively by providing physical, relatable examples of how our brains tune stuff out. I quickly found myself drawn into the article and interested to learn more.

A summary of why encryption wouldn't have prevented General Petraeus from getting caught. Like the quote: "If you think cryptography is the solution to your problem, you either don't understand cryptography or you don't understand your problem."

"With end-to-end encryption in place, not even WhatsApp's employees can read the data that's sent across its network. In other words, WhatsApp has no way of complying with a court order demanding access to the content of any message, phone call, photo, or video traveling through its service. Like Apple, WhatsApp is, in practice, stonewalling the federal government, but it's doing so on a larger front-one that spans roughly a billion devices."

The thing I found very interesting about this article is the discussion about ex-NBA owner Donald Sterling. Yes, his comments were horrifying, but he said things in the privacy of his home. I guess what I, and this article, are trying to say is that privacy is dead and all information is vulnerable.
