With the advances in multicore hardware and virtualization technologies, and the demand for highly responsive, resilient, and elastic systems and increasingly sophisticated applications, an array of reactive data stream processing libraries have been born to address the needs. Reactive Streams is an initiative to provide a standard for asynchronous stream processing with non-blocking back pressure. This presentation will go into some details on how streams leverage on the underlying multicore processor to achieve parallelism. It will explain the push vs the pull streaming model. It will then use a simple use case with code examples to illustrate the different reactive API usages.

In the accessibility community the big secret is that fixing the accessibility of your application or web site will make all of your users much happier, not just the users that require accessibility. Many of the problems that will completely block a person with a disability from using your product are the same frustrations the rest of your users also experience.

In this talk I will cover ten common frustrations that everyone has with web sites and applications and explain how to fix them and make all of your users happier. As developers, by thinking about the accessibility for users with disabilities at the beginning of creating software solutions, you can solve these problems for everyone.

Continuous Integration and Delivery for the Serverless Age

As developers, our goal should always be to deliver good software always. This is a hard goal too achieve. A good place to start is to remove the chance for error by automating tasks. Workflows that have many steps or are very repetitive are ideal candidates. Some jobs that fit this description are: building, testing and deploying.

In this session we will cover how to build a development pipeline, with no servers to manage. That will allow us to control our release process and deliver predictable results.

We live in a world where web technologies have dominated the software development. Even traditional desktop software that once was never thought possible to work in browsers are now developed using nodejs and packaged using Electron, take VSCode as an example. At first, the idea of such dominance of the web may sound limiting; however, this is quite the opposite. We can take advantage of a unified stack and multiply its value across different platforms: entering the Multiplying Architecture! The Multiplying Architecture is a set of libs, patterns, and techniques that provides the right level of abstraction, allowing developers to distribute the same features in different places or platforms.

Kubernetes enables development of cloud native microservices or making traditional applications more technologically advanced with containers. Most Kubernetes solutions are offered on top of VMs, so there is a room for further improvements. Implementing nested architecture of application containers running inside system containers opens additional flexibility of resource allocation & management, accelerates provisioning of clusters & pods, as well as cuts the overall costs. During this session we?ll review how to run Kubernetes cluster inside nested containers, what configurations should be taken into account, and how to overcome the barriers on the way to more efficient Kubernetes hosting.

Cloud-Native has become a big buzzword around the world, a term that is practically used by everyone at all times. But what does it mean? What are the advantages it brings to your application and your day as a software developer or architect? What's new in the Java world, and what are the steps to follow for a native cloud application? This presentation is a step-by-step guide that will practically guide you through implementing Cloud computing services effectively and efficiently.
