Not totally unexpected: Odds of rocket landing successfully today are still less than 50%. [1] [1] https://twitter.com/elonmusk/status/587704139225759744
I think Musk said he just made up the original 50% odds.

Such good motivation to want to be an even better programmer / engineer / scientist. So inspiring what mankind is capable of when we work together.
You guys know we are looking for software people, right? http://www.spacex.com/careers
Optimistic that in the distant future we will be eligible.

That stage 2 engine nozzle really glows hot! Looks hot enough to melt, but holding together impressively. Also, the exhaust into the vacuum looks like a messy grey cloud, not the bright cone I might have expected. Very cool. Or hot.
Yes! Amazingly, although the nozzle looks just like a bell-shaped piece of sheet metal, it in fact uses "regenerative cooling" which means the nozzle is full of small pipes which wind back and forth like a radiator. The rocket fuel is passed through these pipes before combustion, resulting in a heat exchange which is doubly beneficial, keeping the nozzle (relatively) cool and also heating up the rocket fuel so it combusts more efficiently.

Yep, since there is no atmospheric pressure squeezing it into a cone shape, the exhaust just kind of flies everywhere!
Could someone explain why it's (apparently) so much harder to land on a barge than it is to dock with the ISS?
Landing a rocket on a barge involves dealing with gravity, wind resistance, air currents and the crazily unstable centre-of-gravity of a large vertical tube balancing on some rockets.
