Blah blah blah functional programming blah blah blah blah concurrency…

There’s a lot of talk out there about functional programming, and a lot of different ways to manage the complexity of handling thousands of users all interacting at the same time. Whether it’s a multi-user game, web site, cloud application, or networked database application, you’ve got a lot of tools to choose from. Maybe Clojure, Scala, or the new Java 8 features will work great for you. On the other hand, maybe you’re facing the really big problem.

For industrial strength, natively parallel programs that scale effortlessly with larger and larger multicore systems, you need Erlang.

Learn it right here, from the creator of Erlang, Joe Armstrong. Now in beta at pragprog.com/book/jaerlang2.

Programming Erlang, 2nd Ed.

Using Erlang, you’ll be surprised at how easy it becomes to deal with parallel problems, and how much faster and more efficiently your programs run. That’s because Erlang uses sets of parallel processes—not a single sequential process, as found in most programming languages.

Joe Armstrong, creator of Erlang, introduces this powerful language in small steps, giving you a complete overview of Erlang and how to use it in common scenarios. You’ll start with sequential programming, move to parallel programming and handling errors in parallel programs, and learn to work confidently with distributed programming and the standard Erlang/Open Telecom Platform (OTP) frameworks.

You need no previous knowledge of functional or parallel programming. The chapters are packed with hands-on, real-world tutorial examples and insider tips and advice, and finish with exercises for both beginning and advanced users.

The second edition has been extensively rewritten. New to this edition are seven chapters covering the latest Erlang features: maps, the type system and the Dialyzer, WebSockets, programming idioms, and a new stand-alone execution environment. You’ll write programs that dynamically detect and correct errors, and that can be upgraded without stopping the system. There’s also coverage of rebar (the de facto Erlang build system), and information on how to share and use Erlang projects on github, illustrated with examples from cowboy and bitcask.

Erlang will change your view of the world, and of how you program.

Come and get it right now from pragprog.com/book/jaerlang2.
