Every day we imagine some new apps we'd love to have: having an application to allow people to submit talks, to register new holiday requests, expense reports, simply get data from one site and combine it with data from another site and display that, etc. This is the long tail of application.

However in most cases we just drop the idea and continue with our life because we know it would take days or weeks to be able to develop that quickly before you could reap the benefits.

What if there was a way to have these apps developed and working in just a few minutes!

We'll demonstrate how a next generation wiki platform allows to do just that by using the XWiki open source project as an example.

This talk will demonstrate advanced testing practices used by the XWiki open source project, and using Java, Maven, Docker and Jenkins:

• Testing for backward compatibility with Revapi and an associated strategy
• Testing for coverage with Jacoco and defining a viable strategy for slowing improving the situation
• Testing the quality of your tests with Descartes Mutation testing
• Automatically enriching your test suite with DSpot
• Testing various configurations with Docker containers and Jenkins

We'll demonstrate how a next generation wiki platform allows to do just that by using the XWiki open source project as an example.

When developing a web application, the traditional way is to develop the application from scratch using a general purpose language such as PHP, Grails, Play, Java/JSP, etc.

This presentation will show that a next generation wiki (examples based on XWiki: http://xwiki.org) can be used as a web development platform to develop applications on top of it, providing a strong infrastructure scaffolding to building web applications.

The advantages are similar to those of using an application sever. However whereas an application server offers technical services only, a wiki platform offers higher level services such as content management, rendering, storage, WYSIWYGeditor, user management, and a lot more.

Not only are these services offered, you can develop using them in your traditional IDE or in the runtime, directly in wiki pages. This allows developing web applications extremely quickly, collaboratively and with a fast turnaround time, which is perfect for adhoc web application development.

Wikis have been evolving dramatically in the past few years and they are no longer the first generation wikis we used to know like Wikipedia. This session will be an eye opener showing all the capabilities of the next generation wikis. Examples will be mostly from XWiki open source project usages in the wild (http://xwiki.org).

Presents http://rendering.xwiki.org/ a generic engine for transforming content in a given syntax (mediawiki, confluence, JSPWiki, Markdown, HTML, XWiki Syntax, etc) into an output format (PDF, HTML, XML, etc), applying optional transformations.

This framework is generic and can be used outside of XWiki easily into your own Java applications.

This talk aims to share the benefits and challenges of running an Open Source Community and at the same time having companies selling services around the software. It will cover how the XWiki Open Source Community is managed in a full Open Source way, open to any participants regardless of their interests, and how the employees of private companies including XWiki SAS manage their roles as members of the community. We will also touch on XWiki SAS' approach to support the Open Source project. Finally, we will discuss how the company, as well as developers and users, benefit from a fully Open Source approach.
