This is a re-upload of a video that was originally on the Oracle Developers channel (id VSdnJDO-xdg, I think it's private but you can find it on the wayback-machine). The talk was given at the JavaOne 2015 conference (October, apparently). A transcript is available at github (dot) com/matthiasn/talk-transcripts/blob/master/Hickey_Rich/ClojureMadeSimple.md
Here's the original description:
In the seven years following its initial release, Clojure has become a popular alternative language on the JVM, seeing production use at financial firms, major retailers, analytics companies, and startups large and small. It has done so while remaining decidedly alternative-eschewing object orientation for functional programming, C-derived syntax for code-as-data, static typing for dynamic typing, REPL-driven development, and so on. Underpinning these differences is a commitment to the principle that we should be building our systems out of fundamentally simpler materials. This session looks at what makes Clojure different and why.
