In The Trenches With Tomster, Upgrading Ember.js & Ember DataStacy London
A few months after I started working with Ember.js & Ember Data at my new job we began a project to upgrade both. There were parts that were a breeze and others that were quite tricky. This talk walks you through some of the challenges we faced and how we solved them as well as how we began to prepare for the Ember 2.x architectural shift. Hopefully this talk will help save you some time when you decide to upgrade your Ember web application.

Eclipse IAM, Maven Integration For EclipseCarlos Sanchez
Eclipse IAM, Maven Integration For Eclipse at ApacheCon EU 2009 in Amsterdam
http://www.carlossanchez.eu/
Eclipse IAM (Eclipse Integration for Apache Maven), formerly "Q for Eclipse", is an Open Source project that integrates Apache Maven and the Eclipse IDE for faster, more agile, and more productive development. The plugin allows you to run Maven from the IDE, import existing Maven projects without intermediate steps, create new projects using Maven archetypes, synchronize dependency management, search artifact repositories for dependencies that are automatically downloaded, view a graph of dependencies and more! Join us to discover how to take advantage of all these features, as well as how they can help you to improve your development process.
A gentle Introduction to the concept of Progressive Web Apps, explaining the key concept needed to build a website/app that works even when your user is on a flaky network.
*Webinar* Learn from the Experts: How to Boost Test Coverage with Automated V...Applitools
Watch full webinar recording here: https://youtu.be/HFxL_658Gcg
Listen to Fortune-100 Test Automation Expert Joe Colantonio present this hands-on webinar, and learn how by implementing large-scale automated visual testing, he was able to dramatically increase coverage, reduce maintenance, and substantially boost test robustness, efficiency, and ROI.
In order to help you release faster and better, while avoiding functional and visual regressions, Joe dives deep into the following real-life use cases:
* Automating cross-browser UI validation
* Adding full UI regression coverage to existing automated tests
* Handling dynamic content in visual tests
In addition, Joe covers the basics of automated visual testing, including a live demo of adding visual regression and cross-browser layout testing to existing automated tests using Applitools Eyes.
Hastening React SSR - Web Performance San DiegoMaxime Najim
Hastening React SSR with component memoization and templatization: React is a best-of-breed UI component framework allowing WalmartLabs to build higher level components that can be shared and reused across pages and apps. In this presentation, Max Najim and Naga Malepati from WalmartLabs will peel through the React codebase to add a component caching/memoization optimization. The will use a require(..) hook to inject their optimization while avoiding the need to fork the React codebase. And, they will review the caching optimization.
Room with a Vue - Introduction to Vue.jsZachary Klein
Angular has brought MVC & dependency injection to the browser, while React nudges developers towards a simpler, functional approach to view rendering. What if there was a tool that took the best ideas from both of these titans, giving us simple, expressive components while still including enough “magic” to significantly boost developer productivity?
Enter Vue.js
In this talk we’ll get to know this new kid on the frontend block, contrast Vue with it’s better known rivals. We’ll explore the ecosystem: state management with Vuex, routing with Vue-router - and see why Vue.js might not be just another JavaScript framework.
Workshop on how to build Vaadin Add-ons. We introduce two styles of building Vaadin add-on components for Vaadin: integrating an existing GWT widget (DatePicker), and integrating an existing JavaScript library (three.js).

It’s trivial today to start writing and debugging some React code, but it’s not 100% clear how to properly deploy the application, manage versions and what implications that has on the build configurations. Especially if you want to allow different versions for different users in order to perform some A/B testing, testing new features in production environment, come up with some UI experiments, or gradually roll out new features for a subset of users.
In this presentation I hopefully covered all that.
In this talk, I'll show you how you can build Alfresco ADF applications using the new version 3.0.0. The new ADF versions include a number of new features and some breaking changes with the past that will make your life easier, I'll show you how to take advantage of it and embrace the change.
Modular Test-driven SPAs with Spring and AngularJSGunnar Hillert
Single-page Applications (SPA) are all the rage these days and with them there is an avalanche of new tools, libraries and frameworks we need to know. But what does this mean for us as Spring developers? In this session we will give you an overview of the current landscape and illustrate the choices the Spring XD team has made for its user interface. What do I use to write SPA applications? How do I integrate them into existing Spring-based backends? How do I build them? Can I integrate them into my existing Gradle or Maven build processes in order to achieve complete build automation? How do I integrate realtime messaging using Spring's SockJS/WebSocket support? In this talk we will answer these and many more questions. We will cover frameworks such as AngularJS, Bootstrap, RequireJS; tools like Bower, Grunt, Gulp; and also talk about testing using Karma and Protractor.

The number of APIs made available for Google products has exploded from a handful to a slew! Get
the big picture on what is possible with the APIs for everything from YouTube, to Spreadsheets, to

in common. After this session picking up new Google APIs will be a snap.
As the de facto standard for large-scale data processing in the Java world, Apache Spark is the logical choice when you want to investigate big data processing. As a matter of fact, most resources online refer to the Scala API that is exposed by Spark. What to do if you and your company are much more comfortable with Java than the Scala language? These slides give pointers whether it makes sense to learn and introduce an entirely new language just for your big data processing.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
