1. With Xamarin now free for everyone, the popularity of the cross-platform framework is increasing rapidly. We’ve now had the time to play around with it, now the time has come to build serious apps with it.
    In this session, you’ll learn how a real-world Xamarin application architecture is built, with an emphasis on testability and maintainability. The app we’ll look at is called MyTrains, an application used to book train journeys.

    You’ll see an architecture that has proven itself over different projects already. The architecture is using the MvvmCross framework. You’ll see how the architecture is built from the ground up, starting with model, the repositories and the services. On top of that, we’ll build the view models which will be used by the views in the iOS and Android apps. Along the way, you’ll see how MvvmCross uses data binding and commanding and how navigation is handled in MVVM

    You’ll walk away with an example of how real applications in Xamarin should be built. You’ll be able to use this as your starting point for your next Xamarin application.

  2. Elixir and F# are two languages that are loved by their users (and for good reasons). Both are functional. Both are expressive. Both are growing up as the smarter, cooler, prettier younger sibling in their families. Both share the elegant pipe operator "|>". And that (screech) has pretty much exhausted the list of their similarities.
    In most other ways they are different, and they are good at different things. F# has a great type system. Elixir has a great concurrency model. F# can run on mobile devices. Elixir can handle requests from millions of mobile devices. Even the timescales of their sweet spots differ.

    If both deserve a place in our toolbox how can we use them together? We will explore various interoperability techniques (from loose to tight), and we'll develop an intuition for which hammer not to use on which thumb.

  3. Are you a developer that wants to give back to the open source community? Perhaps you're already a seasoned contributor but you want to get better? Or you want to join the open source movement because, well, OSS is the future? Just look at all the cool tech built with OSS: Node.js, BootStrap, ASP.NET etc.
    Join me to learn about the many ways to contribute, key development tools in OSS projects and tips about what it takes to become a succesful first time contributor and collaborator in this welcoming and open community.

  4. You've probably heard of Orleans as the open-source framework Microsoft uses to build cloud-scale services for products, such as Halo and Azure.
    But how do you use it effectively in your own applications?

    In this architecture talk, John & Sergey discuss several challenges that you will face when building cloud services; introduce several proven, powerful design patterns & practices such as state-machines, smart-caches, and event-sourcing; and some anti-patterns to avoid.

  5. F# is a rich, expressive, general purpose, functional first language designed with the goal of allowing developers to write simple code to solve complex problems.
    While The Book of F# provides a comprehensive tour of the language this session will focus on several of the primary ways F# accomplishes that goal. In just 60 minutes we'll discuss what it means to be functional-first, the advantages of the functional-first paradigm, and several key language features including curried functions, partial function application, record types, discriminated unions, pattern matching, units of measure, type providers, and computation expressions.
