Too bad there is technical problem with the Rust talk, hope it can be recovered, :(
or, maybe can be compensated by this one: https://air.mozilla.org/guaranteeing-memory-safety-in-rust/
and ...... for those who like tech conferences videos, like me, here is all the videos from NDC Oslo 2014, and there are MANY interesting content: http://vimeo.com/channels/ndc2014/
for example , here is a list of C++ sessions, very nice http://olvemaudal.com/2014/06/06/videos-cpp-track-ndc-2014/
and there are very nice C#/.NET sessions as well, and many other topics, very interesting.
