Sponsored by Goldman Sachs. Java 8 has Streams, Scala has parallel collections, and GS Collections has ParallelIterables. Since we use parallelism to achieve better performance, it's interesting to ask: how well do they perform? We'll look at how these three APIs work with a critical eye toward performance. We'll also look at common performance pitfalls.
Stuart Sierra discusses various Clojure features: protocols, records, DI, managing startup/shutdown of components, dynamic binding, interactive development workflow, testing and mocking.
Brian Goetz explains how lambda expressions are implemented using the invokedynamic instruction introduced in Java SE 7.
Sponsored by New Relic. Ashley Puls introduces three common byte code manipulation frameworks: ASM, CGLib, and Javassist, providing enough detail to get one started.
Eva Andreasson has a fairly entertaining and yet painful presentation around garbage collection that will probably will end with more questions than answers.
Jack Singleton discusses how to improve code readability and maintainability in Scala, and how to be productive with Options, Immutability, and the Collections library.
Martin Thompson focuses on the evolution of Java and how it contrasts to C/C++, covering the cultural challenges of pushing the limits of performance and how to collaborate with industry experts and organize teams, which often stands at odds with the culture in many organisations.
In this solutions track talk, sponsored by Oracle, Simon Ritter looks at how Embedded Java and a Raspberry Pi were used to communicate with the diagnostic and management systems of an Audi S3 and process the data, and how JavaFX has been used to provide an in-car information system for less than $200.
Lance Walton shares the experience of a small team building a trading platform in 6 weeks in Scala and Lift while fighting against an opposing organizational culture.
Josh Suereth discusses Scala: expressions, abstracting behaviors, FP & OOP, Futures & Promises, libraries with implicit classes and value classes, tracking lexical state with implicit values.
Adam Warski shows how to replace features of DI containers with plain Scala code using MacWire, and adding interceptors using macros.
