Summary Adrian Cole discusses his jclouds project, which is an open source library that helps Java developers get started in the cloud and reuse their Java development skills. Cole also talks about some of the challenges of creating a cloud agnostic library, such as the use of different hypervisors and that various cloud implementations are written in different languages, such as VB, Python, Ru...

Summary Kresten answers questions about current programming languages and problems they solve. He also tries to look at what is missing for addressing issues we face today such as concurrency. He discusses its importance and tries to portray the language that would take us to the next level helping to tackle these issues easily.

Summary This presentation discusses the functional programing paradigms used to build Buy a Feature , (a multi-user, web-based, real-time, serious game) including Actors, event streams,and immutable data structures. Both Scala and the lift web framework are briefly covered. Also covered: application defects, adding new features, and using functional paradigms for a real-world web application. B...

Summary This presentation discusses Scala (a hybrid Object Oriented and Functional language) and Lift (a Scala-based web framework with features based on Scala pattern matching and functional composition). Lift's O-R mapper supports type-safe query building via Scala's type system. Lift abstracts away the HTTP request/response cycle by associating functions with HTML page elements. Bio David Po...

Summary Jonas Bonér talks about Scala: using OO and the type system to create reusable components, using closures, high-order functions, immutability to create coherent and deterministic code, using Actors to create concurrent and event-driven systems, and using ORM, AOP, DI and Testing with Scala. Bio Jonas Bonér is a programmer, mentor, speaker and author. He has worked at Terra...
