Coursera/Stanford have a crypto course going on right now. It's already well under way but you can watch all the videos and (I believe) still do the quizzes and just pass on the certificate.

In contrast, I'd suggest that in this case, government regulation might actually promote innovation. It'll help get rid of the dirty money-milking schemes and promote increasing revenues with real forward progress
I loved Mountain Lion and also found it to be very stable. I stayed on it as long as I could, but the new versions of several of the apps I use required Mavericks, and after holding out for a while I upgraded. Mavericks was when I started noticing issues... Graphics driver issues, trackpad gestures randomly not working for periods of time, WindowServer crashing when opening the notification center (wat?), so on and so forth. Mac OS is still my favorite, but I've gotten an irking feeling that in the interest of capturing the mainstream market and making things look pretty and full of features, Apple has skimped on stability and quality. Just my two cents
In addition to the frontend issue mod mentioned, it often happens accidentally without any errors or warnings when using a VARCHAR in a relational database, which have a maximum length. If the username field is VARCHAR(20), the application ignores database truncation warnings, and the developer didn't think to check the username length before storing it in the database, it'll truncate a 21-character username without you knowing. This comes down to the devs using sensible field lengths and handling edge cases.
Maybe I'm biased but I feel like they're a little late to the party and this just isn't up to par. Too many restrictions, no ecosystem, weird design...
