Coding Horror did a great experiment with their readers where they provided several samples of the same song at different bitrates and then had everyone vote on which they thought sounded best. The result? People could only tell the difference between 128kbps and everything else, and even that was not overwhelming. In fact, 160kbps beat CD!

They should have done the native implementation first.

From TFA: "...the NSA made an enormous breakthrough several years ago in its ability to cryptanalyze, or break, unfathomably complex encryption systems employed by not only governments around the world but also many average computer users in the US."

...but to what extent do encrypted communications via SSL/TLS hinder this new listening post? What good is recording everything you say if it's cyphertext? Or is the assumption that with this massive new datacenter and some dastardly unpublished NSA attack vectors they'll be able to brute force decrypt everything?
