Clojure is a functional language with powerful mechanisms for implementing polymorphic behavior, including for types that you did not create. This talk explores how Clojure solves "the expression problem" common in object-oriented languages using protocols, types and records, and multi-methods. Topics include defining these constructs, applying them to types defined by you or others, and how they map to underlying JVM constructs.

Datomic is a new database with an intriguing distributed architecture. It separates reads, writes and storage, allowing them to scale independently. Queries run inside your application code using a Datalog-based language. Spreading queries across processes isolates them from one another, enabling real-time data analysis without copying to a separate store, opening full query functionality to clients of your system, and more. This talk explores Datomic's architecture and some of it's implications, focused entirely on technical details.
