Mike Williams, co-creator of Erlang discusses the history of and influences on Erlang as well as languages and paradigms used at Ericsson for large scale development and embedded programming.
Larva is a runtime monitoring system that uses AspectJ to weave monitoring into Java code and can check the correctness of the program using an FSM; Elarva is an Erlang version of the tool.
Simon Thompson and Huiqing Li explain refactoring with functional languages and Wrangler (Erlang) and HaRe (Haskell). Also: how Wrangler's ad-hoc mode allows everyone to write custom refactorings.
Jonas Bonér explains the Akka project and the types of actors it offers as well as its transactional features. Also: a preview of how Akka 2.0 changes the management of (remote) actors.
Orion Henry explains what make Heroku's PaaS tick, in particular the new extensible Cedar stack as well as Doozer, the implementation of the Paxos algorithm created at Heroku.
Justin Sheehy and Damien Katz discuss Riak and CouchDB, the strengths and trade-offs of different approaches to NoSQL, and why both databases are written in Erlang.
Kostis Sagons talks about how type checking can help with a dynamic language like Erlang and how static analysis tools like Dialyzer or automated refactoring tools like Tidier help keep code clean.
Bob Ippolito talks about building web services with the Erlang-based MochiWeb and the differences to the Yaws web server, the strengths of Erlang and Python, and more.
Ville Tuulos talks about Disco, the Map/Reduce framework for Python and Erlang, real-world data mining with Python, the advantages of Erlang for distributed and fault tolerant software, and more.
Gregory Collins talks about Snap, a high performance web framework for Haskell, where it fits in the web framework spectrum, the Iteratee I/O model, Haskell performance and much more.
Francesco Cesarini and Simon Thompson discuss how Erlang's design allows fault tolerance and resilience, modular error handling, details of the actor model implementation and distributed programming.
