This section deals with Erlang data types and pattern matching. Functions, modules, and BIFs are discussed. Before the exercises, the Erlang shell, useful shell commands as well as Emacs and its Erlang mode are introduced.
The Sequential Programming section comprehends conditional evaluations, guards and scope of variables. It then introduces recursion, with a special emphasis on different recursive patterns, tail recursion, and space saving optimizations. Before the exercises, libraries and their manual pages, possible run time errors and the debugger are demonstrated.
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. Before the exercises, a demonstration of the Process Manager tool is given.
Process Error Handling
This section introduces the simple but powerful error handling mechanisms in processes. It looks at process links, exit signals and their propagation semantics. How robust systems are built in Erlang are discussed, and an example from the Process Design Patterns section is re-implemented, making it robust.
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. This will be a hands on tutorial. Make sure you come with your laptop having installed Erlang and your favourite editor.
Francesco Cesarini is the founder and Technical Director of Erlang Solutions. He has used Erlang on a daily basis since 1995, starting his career as an intern at Ericsson’s computer science laboratory, the birthplace of Erlang. He moved on to Ericsson’s Erlang training and consulting arm where he worked on the R1 release of OTP, applying it to turnkey solutions and flagship telecom applications. In 1999, soon after Erlang was released as open source, he founded what has today become Erlang Solutions. With offices in seven countries and three continents, they have become the go to partners for scalable, highly available end to end solutions, running conference sand providing support, consulting, training, certification and systems development. As Technical Director, Francesco is leading the development and consulting teams at Erlang Solutions adb is responsible for the product and research strategies of the company. He is also the co-author of Erlang Programming, a book published by O’Reilly. He lectured at the IT University of Gothenburg for over a decade, and since 2010, teaches the concurrency oriented programming course at Oxford University. You can find him rambling on twitter using the handle @FrancescoC.
