Hint: These are only the intro slides for the lice coding & demo (the recording will be published on YouTube). On-boarding new UI5 developers, time from checkout to deployment, Code Review, centralized CI/CD, UI5 tooling… With the right setup it's a no-brainer! In this session I’d like to show you an approach that I’ve been using successfully for years now. Learn and see how you can scale your UI5 projects for multiple developers and teams! This session will cover: - Local dev environment - 4 standard project templates: app, component, library, FLP plugin - Automated installation of the SAPUI5 SDK - Integrate thirdparty js libs via NPM dependencies (i.e. moment.js) - Integrate js libs via NPM from your own internal/external git repos - Managing dependencies from your ui5 apps to ui5 libs/components + run everything even on localhost - Integrating custom themes even on localhost - Reducing risks & creating "Shared Understanding" with code reviews (Gerrit/git) - Test automation, Code Coverage & Test Driven Development - Allow your developers to use latest JavaScript features via Babel - Deploy to NW ABAP from localhost & Jenkins using the CLI (without Eclipse, without SAPGUI)

This presentation origins from a webinar presented by Luís Faria. The webinar presents the SCAPE developed tools Scout and C3PO and demonstrates how to identify preservation risks in your content and, at the same time, share your content profile information with others to open new opportunities. Scout, the preservation watch system, centralizes all the necessary knowledge on the same platform, cross-referencing this knowledge to uncover all preservation risks. Scout automatically fetches information from several sources to populate its knowledge base. For example, Scout integrates with C3PO to get large-scale characterization profiles of content. Furthermore, Scout aims to be a knowledge exchange platform, to allow the community to bring together all the necessary information into the system. The sharing of information opens new opportunities for joining forces against common problems. The webinar was held 26 June 2014.

HDF Project Update

The HDF-EOS Tools and Information Center

HDF OPeNDAP update

The HDF-EOS Tools and Information Center

It's true: Drupal 8 includes big and exciting changes to its core and how Drupal code is written. These include using outside PHP libraries (Guzzle, Symfony, etc) as well as embracing PHP 5.4 and object-oriented code. Scary, right? Definitely not! These changes give Drupal 8 so many "wins" and new possibilities that you're going to absolutely love it. In this keynote, we'll explore the changes together and start to realize all of the wonderful things that each will bring. These include a (much) larger community, many more libraries you can use, higher quality tools, easier future upgrades, and some fantastic new features. And because Drupal uses Symfony, you'll easily be able to use Symfony (or its little brother Silex) for any non-CMS projects. Being a great Drupal 8 developer means being a great PHP developer. Of course, Drupal 8 has its criticisms: it will be too hard for new developers to learn, or it will not be useable for smaller sites. We'll take on these concerns directly and see why they are valid, but exaggerated.
