The Calligra Suite (http://www.calligra-suite.org/) is a continuation of what was long known as KOffice, the desktop office suite from KDE. During the last year, it has evolved into a much more powerful product and platform. Calligra is now useful on both the desktop and on mobile devices.

We will introduce the concept of an Office Engine and show how it can be used as a basis for applications with many different user interfaces. We will show examples on the desktop, on mobile devices and show a prototype of a UI for touch tablets with touch features.

We will also outline the future of the Calligra Suite and show how the participants can help form the future by contributing to the fast-growing suite.

Marijn started contributing to KDE and KOffice late 2005, initially working on KOffice's (now Calligra) support for .xls files, and improving KDE on Mac OSX. During the Google Summer of Code in 2007 and 2008, he further contributed to KOffice and worked on improving KDE on Maemo and other mobile platforms.

Currently employed by KO GmbH, Marijn is also the maintainer of Calligra Tables, the application formerly known as KSpread.

Speaker: Rob Oakes

There are many good reasons to use open source technology. These include it's attractive cost (free), it's scalability and robustness, and its large and enthusiastic community. But these reasons overlook what might be the most important benefit of Open Source (at least to the technical and scientific writer), the ability to produce a beautiful product from a cohesive and unified workflow. Open Source technology provides tools to aid in research, collaboration, illustration, typesetting and layout. This presentation will introduce the open source publishing and typesetting ecosystem -- LyX, LaTeX, Kile, Inkscape, Scribus, Sigil -- and how the tools can be used together to capture and disseminate inspired thinking.

Rob Oakes is a biomedical engineer and researcher based in Salt Lake City, Utah. In addition to a love of science and research, he is also fascinated by illustration, typesetting, layout, and design. When not trying to elucidate the inner workings of the heart's electrical system, he likes to spend his time drawing and painting. From 2004 to 2005, he was the production editor for Utah's Health: An Annual Review, a public health journal published by the University of Utah.

Speaker: Frank Karlitschek

The advantages of storing data in the cloud are many: ubiquitous access to data from multiple devices, social interaction with millions of others on the web and no extra software to install. However, the data is often owned by several different organizations, which don't easily allow interaction or sharing of data among them. Besides these convenience issues, there are also problems with privacy and security as well as the potential for one hardware failure to make the data of thousands of users impossible to access. Taken together, the cloud is not perfect.

ownCloud solves this problems because it is designed to run on the server or computer of the user. So the user has the benefits of cloud computing but controls the data. ownCloud integrates perfectly with KDE desktop applications so that the users has cloud features combined with the power of KDE applications.

This talk presents the current state of ownCloud and the plans for ownCloud 2.0 and 3.0

Frank Karlitschek was born 1973 and lives in Stuttgart, Germany. He is a KDE contributor since 2001.

Speaker: John Layt

Geolocation and mapping are an increasingly popular feature for many types of applications, from geotagging your photos to "checking-in", displaying local weather forecasts, or navigating your way to the nearest pub. While a number of KDE applications have such geolocation features, and Plasma provides a geolocation data engine for applets, there is no one shared geolocation library or API within KDE, leading to duplication of effort and inconsistency across the workspace.

The first part of the talk will cover possible use cases for geolocation in KDE, a brief survey of the existing use of geolocation in KDE, and a discussion of the possible options for a common geolocation API in KDE.

The second part of the talk will be a short demo of Marble, the KDE Virtual Globe and mapping library. The demo will show many of the new features in Marble 1.0 and discuss the status of the project, followed by a short introduction to using libmarble to provide geolocation and mapping services for your app.

John Layt is a KDE hacker from New Zealand who works on Printing, Localization and Calendar Systems in the KDE Libraries, and is maintainer of the KHolidays library in KDE PIM. John has been interested in GIS, geolocation and mapping since he tried to write a KDE virtual globe in the early 2000's, but is now a contented Marble user.

Speaker: Thiago Macieira

The Qt Open Governance project was started in July 2010 at Akademy, in Tampere, aiming to provide a more transparent and accessible way to governing Qt's development. The chosen model was that of an Open Source project, like KDE is. The objective is to increase the access from the community of non-Qt developers to the decisions and every-day work in Qt, allowing anyone with the will and skills to participate. Once it's in place, the Qt Open Governance will allow contributors to set their own roadmap and be able to execute it, independent of how Nokia's own roadmap looks like.

The project kicked off with a mailing list and wiki to discuss in the open how the Open Governance should be. In the months since then, the community has discussed many different topics and arrived at conclusions that should help the Qt team steer their creation of the model.

Since January 2011, the Qt team has been working in high-gear mode with some consultants in order to see this happen. The work has been divided into a couple of streams, like Development Workflow, Communication, Web Presence and Marketing, etc. These streams work at different paces and have different goals, which will be presented in this session.

The model for decision making and acceptance of code has also solidified. Consisting of a very flat community with Contributors, Approvers and Maintainers, the model is intended for facilitating contribution and diminishing the barrier of entry for participating. The model is founded on the principles of Meritocracy, Transparency and Inclusion, allowing one to "rise through the ranks" (however few there may be) quite quickly. At the same time as they give greater rights, higher "positions" also include greater duties, which will be explained in this session.

Finally, the community of developers will revolve around a tool for reviewing and approving code, integrated with Qt's Continuous Integration system. This session will give the basics of this tool, explaining how easy it is to use and the principles behind it. It will also show how the same tool could be used in KDE for improving the quality of its own contributions, like it is done with the Review Board.

Thiago Macieira, Senior Product Manager for Qt Developer Frameworks originally joined Trolltech in 2006. Since joining the company, Thiago has worked as a developer and release manager for Qt. Based in Oslo, Norway, he has an MBA and a double degree in Engineering. These days, Thiago is a product manager and spends the majority of his time thinking about the future of Qt, focusing on MeeGo and Open Source, and giving presentations to anyone and everyone that will listen!
