Basic & Sequential Erlang
This section deals with Erlang data types and pattern matching. Functions, and modules are discussed. It continues by introducing recursion, with a special emphasis on different recursive patterns, including tail recursion.
This section describes the creation of processes and their life span. It looks at sending and receiving messages, selective reception, and passing data in the messages. It continues with the various uses of time outs and registering processes, and terminates by showing the generic process code structure. We conclude this section by introducing the simple but powerful error handling mechanisms in processes. It looks at process links, exit signals and their propagation semantics.
Generic Servers and Supervisors
This section introduces the OTP design patterns commonly referred to as generic servers and supervisors. We give an example of a client server application written in Erlang, migrating it to a system using the gen_server behaviour libraries. We wrap up this section by demonstrating how to place the server we’ve just written in a supervision tree.
Delegates who will benefit from this tutorial includes those want to learn more about Erlang and its concurrency model. Attending will put you on the right track in building distributed, fault tolerant massively concurrent soft real-time systems.
In order to get the most out of this tutorial, you must have a good grasp of other programming languages. Having dabbled with http://tryerlang.org is not necessary, but will help. This will be a hands on tutorial. Attendees need to come to the tutorial having downloaded and installed Erlang and the Erlang mode for your favorite editor. You can either download a binary from http://www.erlang-solutions.com/section/98/downloads or build from source down-loadable at http://www.erlang.org/download.html.

Francesco Cesarini is the founder of Erlang Solutions Ltd. He has used Erlang on a daily basis since 1995, starting as an intern at Ericsson’s computer science laboratory, the birthplace of Erlang. He moved on to Ericsson’s Erlang training and consulting arm working on the first release of the OTP middleware, applying it to turnkey solutions and flagship telecom applications. In 1999, soon after Erlang was released as open source, he founded Erlang Solutions. With offices in three countries, they have become the world leaders in Erlang based support, consulting, training, certification, systems development and conferences. Francesco has worked in major Erlang based projects both within and outside Ericsson, and as Technical Director, has led the development and consulting teams at Erlang Solutions. He is also the co-author of Erlang Programming, a book recently published by O’Reilly and lectures at Oxford University and the IT Univertisy of Gothenburg. You can follow his ramblings on twitter.
