Proper distribution of functionalities throughout many machines is very hard, especially when we leave those decisions for later. Akka toolkit gives us many tools for scaling out and we can start using them very early in a development process, enhancing our chances of success. In this introductory talk, I want to go through a very simple example and show snippets of single-noded and sharded implementations.
Akka persistence == event sourcing in 30 minutesKonrad Malawski
Akka 2.3 introduces akka-persistence, a wonderful way of implementing event-sourced applications. Let's give it a shot and see how DDD and Akka are a match made in heaven :-)
Slides for my talk event-sourced architectures with Akka. Discusses Akka Persistence as mechanism to do event-sourcing. Presented at Javaone 2014 and Jfokus 2015.
Event sourcing and Domain Driven Design are techniques that allow you to model your business more truthfully - by expressing it via commands, events and aggregates etc. The new akka-persistence module, included in Akka since the 2.3 release is aimed at easing implementing event sourced applications. Turns out the actor model and events as messages fit in here perfectly. During this session we'll discover how to build reactive, event sourcing based apps using the new abstractions provided, and investigate how to implement your own journals to back these persistent event sourced actors.
Good karma: UX Patterns and Unit Testing in Angular with KarmaExoLeaders.com
If you listen to backend developers, they will tell you that writing unit tests is essential to good karma. Pay it forward with tests and get back a reliable application. But getting unit tests running on the front end in a “real” application can be a lot more challenging. This intermediate-beginner level workshop will cover how to get setup for writing unit tests, and how to write front-end and end-to-end oriented unit tests for a variety of use cases all for AngularJS. We will work from a series of use cases, transform those into formal acceptance tests, write failing unit tests and then resolve those tests writing code with Angular, html/jade/css and node.

CLS & asyncListener: asynchronous observability for Node.jsForrest Norvell
Slides from my presentation at PDXNode in October 2013 before RealtimeConf. Thanks to Tracy Abrahms, Ben Acker, and the rest of the PDXNode community for accommodating and hosting me at the last minute!
Beyond Profilers: Tracing Node.js TransactionsTerral R Jordan
Node.js is fast, but once the code is in production, how can you make sure it's still fast?
In this talk from the Boston node.js meetup on October 9th, I talk about various strategies for monitoring node in production, with an obvious bias towards transaction tracing.
Akka and the Zen of Reactive System DesignLightbend
In order to be successful with asynchronous programming, when coming from synchronous execution models you need to change your mindset and look at things from a slightly different perspective. In order to use Akka at it's best, you will have to change the way you think about application design (loosen coupling in space and time between components), and re-think what you've maybe learned in the past.
In this talk we uncover a number of rules that serve as a guide in designing concurrent distributed applications, how those apply to Akka, and how they can help you in daily app development.
Aimed at developers through architects, Akka team happy hAkker, Konrad Malawski, bends your parameters with regards to application design and asynchronous execution models.
This full day course will give you a hands-on, deep dive into React Native. In this course, you will learn how to build cross-platform mobile applications from scratch using Facebook's React Native.
Over the past few years, web-applications have started to play an increasingly important role in our lives. We expect them to be always available and the data to be always fresh. This shift into the realm of real-time data processing is now transitioning to physical devices, and Gartner predicts that the Internet of Things will grow to an installed base of 26 billion units by 2020.
Reactive web-applications are an answer to the new requirements of high-availability and resource efficiency brought by this rapid evolution. On the JVM, a set of new languages and tools has emerged that enable the development of entirely asynchronous request and data handling pipelines. At the same time, container-less application frameworks are gaining increasing popularity over traditional deployment mechanisms.
This talk is going to give you an introduction into one of the most trending reactive web-application stack on the JVM, involving the Scala programming language, the concurrency toolkit Akka and the web-application framework Play. It will show you how functional programming techniques enable asynchronous programming, and how those technologies help to build robust and resilient web-applications.
s React.js a library or a framework? In any case, it is a new way of working that represents a revolution in the way of building web projects. It has very particular characteristics that allow us, for instance, to render React code from the server side, or to include React components from Twig tags. During this talk we will present React.js, we will explore how to take advantage of it from PHP projects and we will give answers to practical problems such as universal (isomorphical) rendering and the generation of React.js forms from Symfony forms without duplication of efforts.

OVERVIEW
AngularJS is an open-source JavaScript framework, maintained by Google, that simplifies development of single-page applications. This session will provide an overview of AngularJS framework and demonstrate test-driven development of single-page applications.
In this session Andy will present a walkthrough of Angular’s core features such as dependency injector and directives. He will showcase a test-driven development of AngularJS applications using Jasmine and explain Angular’s data bindings that allow for creation of views and controllers that update automatically in response to data changes. He will also demo Angular’s deep linking and front-end validations and present integration with Ruby On Rails back end using AngularJS AJAX abstractions. Finally, Andy will utilize AngularJS directives and components to create reusable UI elements.
In summary, AngularJS is a great framework for creating complex single-page applications. Attendees will leave the talk with a solid understanding of Angular’s test-driven development process.

Barys and Simon talked about Akka Cluster. Cluster Sharding allows to transparently distribute work in an Akka cluster with automatic balancing, migration of workers and automatic restart in case of errors. Cluster PubSub offers the publish/subscribe pattern. Akka Distributed Data offers eventually consistent data structures across the cluster, that allow for keeping the cluster's state.
They talked about the Akka Modules and explained how they interplay. Finally, they shared what Risk.Ident have learned running a reactive application based on Akka Cluster in production for almost a year.
Resilient Applications with Akka Persistence - Scaladays 2014Björn Antonsson
In this presentation you will learn how to leverage the features introduced in Akka Persistence: opt-in at-least-once delivery semantics between actors and the ability to recover application state after a crash. Both are implemented by storing immutable facts in a persisted append-only log. We will show you how to create persistent actors using command and event sourcing, replicate events with reliable communication, scale out and improve resilience with clustering.

This was a talk from DDDSW on Akka.Net, the actor model, concurrency and reactive. It covered what they are as well as an example use case and the lessons learned when running in that use case.
CQRS (Command Query Responsibility Segregation) was all the hype in .NET architecture circles a few years back. But has it faded away? Is it old news? I argue that it hasn't, and the concepts of CQRS are alive and well and probably more widely accepted and considered today than a few years ago. From event-driven systems to the Reactive Manifesto, the principles of CQRS are with us and impacting many different tools. In this session, we'll explore those CQRS principles and how they have manifested themselves in the architectures of choice today. You'll come away with a greater appreciation of CQRS and ideas on how to incorporate those principles in your applications today.
Akka: Simpler Scalability, Fault-Tolerance, Concurrency & Remoting through Ac...Jonas Bonér
Akka is the platform for the next generation event-driven, scalable and fault-tolerant architectures on the JVM
We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction.
Akka is here to change that.
Using the Actor Model together with Software Transactional Memory we raise the abstraction level and provides a better platform to build correct concurrent and scalable applications.
For fault-tolerance we adopt the "Let it crash" / "Embrace failure" model which have been used with great success in the telecom industry to build applications that self-heals, systems that never stop.
Actors also provides the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications.
Akka is Open Source and available under the Apache 2 License.
Migrating from Flux to Redux. Why and how.Astrails
When I started to work with React back in Apr-2015 there were many libraries to manage the application flow. I decided to start with classical FB's Flux implementation to understand what's missed there. Eventually react-redux and redux solved most of issues I had with Flux. This talk is about practical aspects of migration from Flux to Redux.

NodeJS: the good parts? A skeptic’s view (jax jax2013)Chris Richardson
JavaScript used to be confined to the browser. But these days, it's becoming increasingly popular in server-side applications in the form of Node.js. Node.js provides event-driven, non-blocking I/O model that supposedly makes it easy to build scalable network application. In this talk you will learn about the consequences of combining the event-driven programming model with a prototype-based, weakly typed, dynamic language. We will share our perspective as a server-side Java developer who wasn’t entirely happy about JavaScript in the browser, let alone on the server. You will learn how to use Node.js effectively in modern, polyglot applications.

Resiliency & Security_Ballerina Day CMB 2018 Ballerina
Resilience is the ability to recover to a working condition after being affected by a serious incident. Integration programmers have to be aware of such failures and also make their programs robust ro deal with and recover from such failures. In this session, we will look at how Ballerina helps integration developers to write resilient programs and how it helps eliminate or reduce failures due to oversight. Also we will demonstrate core resiliency techniques, such as timeout, retry, circuit breaker, distributed transactions.
Security has become a top priority in cloud native, integration, and microservices programing. In this session, we will look at how to secure microservices and how Ballerina helps developers to write secure programs by providing inherent protection against threats. This will will also include details on the Ballerina compiler's security awareness features and how it prevents mistakes that could result in major security breaches.
