Learn about all the cool new features of Scala 3 and how they impact your day to day development. This talk will refactor existing Scala code from 2 to 3, as well as outline transition process for projects.
We’ll cover the following:
Enums and Top level definitions Deprecating implicits Type system improvements (union, match, etc.) Metaprogramming (inline, macros and typeclass derivation) Additionally, we’ll give advice/guidance on adopting Scala 3 and evolving an existing project.
Ever since we broke apart the front and back-end of our systems, we’ve longed to partially reunite them with a shared language. The benefits of code reuse and shared tooling are compelling but is this nirvana possible? In this session we will explore building both the front (mobile and web) and back-end of an application with a shared Kotlin codebase. You will learn how to setup the build, share code, and deploy the back-end as a serverless app.
Serverless is all the rage but what does it mean for Scala developers? Can we take a plain ol’ Scala function and run it on the cloud with infinite scalability? This talk will explore how to build and deploy serverless Scala and how to avoid startup overhead. We will use Google Cloud as a reference serverless implementation but the concepts are applicable with any provider.
After decades on the outskirts, Functional Programming is finally breaking into the mainstream due to changing needs and paradigms. For instance, Apache Spark has brought FP to many developers due to its function-oriented, big data transformation API. This session will give you a quick intro to FP. You’ll learn from code examples how to make sense of terminology like Higher-Order Function, Functor, and Monad – and you won’t need a math degree!
Apache Kafka has emerged as a next generation event streaming system to connect our distributed systems through fault tolerant and scalable event-driven architectures. Now open source through Apache, Kafka is being used by numerous large enterprises for a variety of use cases. This session will introduce the basics of Kafka and walk through some code examples that will show how to begin using it.
Machine Learning is all the rage today with many different options and paradigms. This session will walk through the basics of Machine Learning and show how to get started with the open source Spark ML framework. Through Scala code examples you will learn how to build and deploy learning systems like recommendation engines.
Refactoring Monoliths to Microservices with Functional Programming (Slides)
Functional programming is growing in popularity for a variety of reasons, but for many, the most compelling reason is that it enables refactoring from monoliths to microservices. This session uses code examples and real-world experiences to explain why moving to FP will make it easier for you to embrace microservices. The code examples use Scala and Play Framework.
In contrast to just a few years ago, most large enterprises are now contributors to and maintainers of open source projects. For many, there are aspects to the contributions that slip through the cracks, causing headaches for legal teams and unnecessary risk for the organization. Things like managing code licenses, contributor license agreements, and patent-related issues are often not addressed. This session describes how your organization can tackle these issues and covers some of the tooling Salesforce has built to help ensure legal compliance with incoming and outgoing contributions.
Reinvent your App Dev Lifecycle with Continuous Delivery on Heroku (Video)
Learn how your team can use modern application development and deployment practices on the App Cloud to build apps with Internet scale and sophistication. We will walk through how we used Continuous Delivery with GitHub and Heroku Pipelines to build a consumer-facing real estate app.
Scala and Functional Programming can be scary at first for those of us coming from the OOP world. With a bunch of new concepts like immutability, first-class functions, implicits, and a ton of language features, it is easy to get overwhelmed when jumping into Scala. This session will provide a gentle introduction to Scala. You will learn the basics and walk away with a solid foundation to build on and be able to apply what you’ve learned to Java 8’s Lambdas.
The world is going Reactive and there are now a number of different ways get there. The Reactive Manifesto states that Reactive apps must be “Elastic” so this session will use code examples and real apps to compare the different models of elasticity in frameworks like the Typesafe Platform (Play Framework, Akka, and Scala), RxJava, Reactive Streams, and NodeJS. Traits like programming model, back pressure, and horizontal scaling will be considered in the comparison.
Architecting Engagement Apps (Video)
Non-blocking, asynchronous, and reactive programming models are all the rage today. This session will explore in-depth why these patterns are important in modern apps. We will drill down and see how to apply them to event-driven web, mobile, and RESTful apps. To illustrate the concepts, we will use Java, Scala, Akka, and the Play Framework as examples.
sbt-web is a new web asset pipeline for Play Framework and other sbt-based frameworks. It can pull dependencies from both Node and WebJars. The pipeline covers all of the phases of client-side development, including: linting, compiling (CoffeeScript, LESS, etc), minification, concatenation, fingerprinting, and gzipping. This session will give you an introduction to sbt-web and show you how to get started using it.
The world is going Reactive but not just for the back-end; UIs are also becoming Reactive. In this session we will walk through how to build an end-to-end Reactive application with Scala, Play Framework, Akka, and AngularJS.
Play Framework is easy to deploy and scale but like any system some optimizations can help things run more smoothly. This webinar will teach you the basics of deployment, configuring thread pools, managing blocking, and common performance pitfalls.
Intro to Scala (Slides)
This is a very brief introduction to Scala.
Architecting Event-Driven Web, Mobile, and RESTful Apps (Slides)
Non-blocking, asynchronous, and reactive are all the rage today. This session will explore why the patterns are important in modern apps and how to apply them to event-driven web, mobile, and RESTful apps. To illustrate the concepts, Java, Scala, Akka, and Play Framework will be used as examples.
This session will teach you how to pull together jQuery, LESS, Twitter, Bootstrap, and some CoffeeScript to build the Client. The Server could be anything that talks HTTP, but this session will use the Play Framework.
