A modular, polyglot architecture has many advantages but it also adds complexity since each incoming request typically fans out to multiple distributed services. For example, in an online store application the information on a product details page - description, price, recommendations, etc - comes from numerous services. To minimize response time and improve scalability, these services must be invoked concurrently. However, traditional concurrency mechanisms are low-level, painful to use and error-prone. In this talk you will learn about some powerful yet easy to use abstractions for consuming web services asynchronously. We will compare the various implementations of futures that are available in Java, Scala and JavaScript. You will learn how to use reactive observables, which are asynchronous data streams, to access web services from both Java and JavaScript. We will describe how these mechanisms let you write asynchronous code in a very straightforward, declarative fashion.

Mobile Apps - Getting Your Idea Across

Guilherme Schmitt

On February 19th I had this presentation at Venture Café in Boston to help people get their mobile app idea across by going through each of the mobile app development phases - from problem definition to creating wireframes. With simple and free tools like Keynote you can materialize your idea into something visual to test it and share it with the world. This presentation is all about how you can be efficient using research and how to iterate on the user experience before trying to come up with a solution on the look and feel aspect - saving money and effort in the long run.
