This talk will start by looking at some of the less well-understood problems with multi-threaded programming—everyone knows about deadlock and livelock, but do you know what the memory model says about concurrent code, and why that makes it even harder to write than you thought?
In this session we are going to talk a bit why JetBrains sees the potential in Kotlin comparing to other JVM languages. Then we’ll see how certain language constructs can be used to make Android more enjoyable. Also we’ll look at a DSL for type-safe dynamic layouts and a simple extension plugin that helps to avoid writing ‘findViewById()’ all the time.
This talk will show off Scala.js and how you can get started using it. Starting from nothing, we will build a number of small Scala.js applications, which will hopefully demonstrate this promise. No Scala experience required.
ReactiveCocoa is an elegant framework that radically changes the way we structure our applications and handle flows of data. However, it’s beauty is somewhat marred by Objective-C! In this talk I will cover the basics of ReactiveCocoa and the principles of Functional Reactive Programming. Through simple practical examples I will show how ReactiveCocoa and Swift form a beautiful partnership.
This talk will leverage the experience of introducing reactive programming into existing imperative, blocking codebases to demonstrate how it can be done and when it can make sense to do so. Not all benefits of reactive programming can be obtained without a greenfield, fully async architecture, but many can. Subjects to be covered will include the mental shift from imperative to declarative, working with blocking IO such as JDBC and RPC, service composition, debugging and unit testing.
If things go to plan, Dave Thomas will contend that we are looking at emerging technology wrongly. By definition, newer will be worse than older, at least in the short term. And yet we jump like lemmings off the bright and shiny cliff. So how do we find a balance?
Diana Larsen, co-author of Agile Retrospectives: Making Good Teams Great, will introduce you to a simple framework for getting better outcomes from retrospective meetings, suggest ways to maintain the relevance of improvement to the work of your team, and provide tips and pointers to get great returns from the time your teams devote to every meeting.
Performance tuning is a methodical and an iterative process. It is imperative to have a performance plan coexist with a product development plan. A performance plan not only serves to document the requirements but also feeds into designing the performance experiments and helps in providing a clear understanding of the performance infrastructural needs.
This talk will be an accessible exploration of the JVM Heap, thread stacks and concurrency primitives on the JVM and how to compose multi-threaded code in Java and Scala.
In this talk we will talk about the design of Netflix’s Mesos framework and the scheduler. We will focus on the following aspects of the scheduler – Bin packing algorithms, scaling in and out of clusters, fault tolerance of processes via reconciliation and processing life cycle events, multi-geography/cross data center redundancy.
