Presentation: Introduction to concurrency (and data structures) in Clojure

Track: Parallel Languages / Time: Friday 10:20 - 11:10 / Location: Berlage Zaal

Clojure is a fairly young functional programming language targeting the JVM (JavaScript and CLR). Its design goals are simplicity and user empowerment, while remaining practical in terms of performance, productivity and interoperability with the host platform.

While there is much to be said about Clojure and it's ecosystem, this talk focuses on Clojure's concurrency model which combines pure functions and persistent data structures with the concept of managed references. We'll discuss managed references, including vars, refs (STM), agents and atoms. We'll also look a bit deeper at the persistent data structures, the "magic sauce" makes this model feasible performance-wise.

Presentation: Introducing Calabash

Track: Designing & Coding For Tablets / Time: Friday 13:20 - 14:10 / Location: Keurzaal

Calabash is a new open-source technology for automated functional testing of Android and iOS apps. Calabash combines advanced automation technology with the Cucumber tool. Developers or QA staff can write executable tests that closely match the use cases for the app. Tests are written in a natural language close to the application business domain, and the cucumber tool can execute those tests on Android or iOS devices or simulators.

This talk will introduce Calabash and LessPainful, which provides test execution as a service. The LessPainful test service runs Calabash tests concurrently on many physical, non-jailbroken devices running various languages and operating system versions.
