Keynote: Glyn Moody, Why Hackers Will Save the World
Keynote: Glyn Moody, Why Hackers Will Save the World The achievements of free software are already extraordinary. As well as running most of the Internet's infrastructure, and powering many of its leading companies, free software is beginning to find wide use in the server rooms of enterprises and on the desktops of general users. It is also increasingly deployed in embedded systems, and for mobile phones. But that's just the start: inspired by the ideas of free software, and building on its innovations, a wide range of other movements have been founded that aim to introduce freedom, openness and transparency to some of the most important areas of human activity. This talk explores their impact. 2009-07-05 15:00-15:45Published 4 months ago

Thorsten Prante, GNOME Zeitgeist
Thorsten Prante, GNOME Zeitgeist This talk and demo will treat the Zeitgeist project. Our focus currently is on supporting personal-information-management activities, such as re-finding of information, but will extend to task and time management (via user-initiated and automatic tagging / labeling) as well as to supporting activities common to general information or knowledge work, e.g., via tracking information development (re-visioning) and diffusion as well as anchoring the user's desktop activities to real-world events, activities, and experiences; thereby also providing for a multitude of entry points for searching and browsing or orienteering. It shouldn't go unnoticed that Zeitgeist can be considered 'spyware for personal use'. This issue (user control, privacy, security) will not be put aside in our talk. The user interface of the first version of GNOME Zeitgeist, to be released in April/May 2009, provides a time-oriented browser with tagging and bookmarking functionality as well as a search engine. It is based on and works with logged journaling data of the user's working with her/his personal (desktop) computer. An overview description of the extensible architecture will be given in the talk. Usage data are incorporated via dedicated logging components or via D-Bus, facilitating functionality spanning multiple applications. An RDF model will also be developed to provide for interoperability. This way, Zeitgeist will reduce fragmentation or compartmentalization of the user experience when, amongst others, going back to information already used, orienting oneself in one's information, resuming work and task switching. This is already tackled by common desktop search engines, but they rather fail to find and present the user's information in the context of their, possibly repeated, usages and exploit the thereby implicitly or explicitly established relationships. The journaling data can be understood as providing extensions to or a generalization of the 'recently used' information access method common to most operating systems, where extension is meant time-wise and spans potentially all information formats of information items which you touch on your desktop, including, for example, text documents, pictures, web resources, instant and email messages, but also contact information, calendar items and other information items related to planning. Thereby, meaningful integration of information items formats is facilitated such as, e.g., across communication formats and tools (e.g., per person) or all the stuff belonging to a certain activity, including comments/reflections, documents, people you met, etc. (via logging the different aspects of the activities). One of the key ideas behind Zeitgeist is to enrich information items with personal usage context, in order to build up a personal context history in turn facilitating a personal experience representation. This representation includes, amongst others, the traces a person left with, on, or otherwise related to information items over time, across applications and possibly across devices. Currently, the domain of Zeitgeist is the desktop and the information a user has touched. It will go beyond this by a) extending its focus across personal computing devices (i.e. personal computing environments, e.g., smart phone and laptop) and b) by including so called z-events, representing information directed to or interesting to a user, e.g., information she/he subscribed to. Currently, users can employ the Zeitgeist UI for going back directly to the time span / day when she/he had last processed your activity, or searching for a file or tag name or a bookmark, while constraining the search or the browsing view via filters such as types of information items. In the future, as noted above, more relationships will be exploited to browse and search your information items: usage-induced, semantic, and explicit grouping and linking. As opposed to the intimacy expressed by many people, and in particular knowledge workers, interacting with their personal computing devices throughout the everyday and across private, professional and educational domains, today, it is striking to observe that this very personal computing environment is not really prepared and in fact offers only limited support in answering the central questions of orienting oneself: 'What did I do?' (retrospective perspective), 'What am I currently doing?' (current perspective, where 'current' turns out to be a very vague term), and 'What have I planned for the future?' (prospective perspective). 2009-07-05 15:45-16:30Published 4 months ago

GUADEC 2009: Owen Taylor, Introduction to the Gnome Shell
Owen Taylor, Introduction to the Gnome Shell The GNOME Shell is a major component proposed for GNOME 3.0. It takes over the window management and application launching roles and provides an intuitive unified experience as the user navigates between tasks and documents. The shell is built on several technologies new to GNOME: the desktop is displayed as an OpenGL scene graph using the Clutter library. It is primary coded in Javascript, and access to the GNOME platform and to low level code written in C is done using gobject-introspection, which eliminates the need for hand-written glue code. The talk is a general interest introduction to the GNOME Shell - it does not presuppose prior experience programming to the GNOME platform. The talk will start with a description of the design ideas and challenges behind GNOME Shell, and move on to a tour of the shell user interface. A high-level overview will given of the technology choices behind the shell and the architecture of the shell, with particular emphasis on how they allow rapid prototyping and sophisticated effects with small amounts of code. The talk will conclude with a look at future work on the shell as we get closer to GNOME 3.0 and how the user interface and technology of the shell can be integrated more deeply with the rest of GNOME. 2009-07-05 15:00-15:45Published 4 months ago

GUADEC 2009: Keynote: Quim Gil
Keynote: Quim Gil Maemo 5 platform development is in the final stage and we are working already on Harmattan, a very special release marking the graduation in the Nokia software strategy. Harmattan will bring a consolidated Maemo architecture driven by Qt and other champion projects from the freedesktop.org, GNOME and KDE communities. Since its debut in 2005, Maemo has pioneered implementing young and established Linux components in mobile devices: GTK+, Hildon, Telepathy, D-Bus, BlueZ... Maemo powers open devices like the Nokia 770, N800 and N810 Internet Tablets, and now is gearing to more mainstream audiences with Maemo 5. 2009-07-04 15:00-15:30Published 4 months ago

Aleix Pol, KDevelop 4
Aleix Pol, KDevelop 4 Soon we will hopefully get a new KDevelop 4 and we would like to present it directly to the KDE developers and the community overall on the Akademy. Since our last version, lots of changes have happened, we think we are creating a useful tool for C++ developers and we want to present it to the KDE community so that we can all take advantage of that. KDevelop has been redesigned from scratch and we even have some features that are unique among all the IDE solutions on the market. and we strongly think they can be very useful to the developer because of its integration to the whole core development stack to make the development even more acessible (language, vcs, buildtool, documentation, etc.) without repeating the earlier versions mistakes. KDevelop has got a new language architecture that is capable to abstract many language features, and not only provide a very powerful code completion, but to get the IDE to understand the code the user is working on, and assist him in many ways. An important aim is to assist the user on the level of programming that makes it hard (Language semantics, inter-file relationships, etc.), which is especially helpful when exploring new code-bases, or when searching for errors. Since the developer can't work with the language alone, KDevelop provides a full integration with different build tools like CMake (Including code-completion and semantics) or Custom Makefiles. That way the user is not only comfortable when developing using his language but by managing his project. There are many other components that KDevelop integrates, like in VCS software, where we can work with many different VCS tools transparently from our solution making it easy to the developer to do some easy tasks. We can integrate as well many different documentation systems to make it easy to the developer to know about what he is developing on and of course we can integrate different debuggers to work with the whole environment in a user friendly way. As a KDE project we would be proud to be able to present it to the rest of KDE developers on this summer's Akademy, we think they would take advantage of KDevelop and we want it to be embraced by the developers. For all these reasons, we are really looking forward to present it on the Akademy. 2009-07-05 15:45-16:15Published 4 months ago

Will Stephenson, Akonadi
Will Stephenson, Akonadi Akonadi enables the efficient implementation of interfaces to users' most important data. This talk presents the benefits of using Akonadi for your project. Akonadi is a service for the storage of personal information: address books, reminders, messages and more. Its modern design allows an integrated experience when storing and accessing user data. A clean, lean design, founded in over 12 years of experience in FLOSS PIM software, followed by three years of development have produced a mature product with a broad range of interfaces and supporting tools. Akonadi is designed to meet peoples' needs in managing the data that defines them, and to extend to accommodate future requirements by being data type agnostic at its core. Its modular design around a minimal storage core allows for extensibility, scalability and customisation to specific deployments. A wide variety of resources make the core capable of storing and accessing many standard PIM data types and services. Akonadi is implemented using standard technologies for portability. Its federated components ensure robustness, and communicate using open protocols allowing Akonadi to be easily extended. It is supported by comprehensive test suites, support tools and documentation. 2009-07-05 11:30-12:00Published 4 months ago

Jürg Billeter, Vala
Jürg Billeter, Vala Vala is a new programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C. The syntax of Vala is similar to C#, modified to better fit the GObject type system. valac, the Vala compiler, is a self-hosting compiler that translates Vala source code into C source and header files. It uses the GObject type system to create classes and interfaces declared in the Vala source code. In this presentation I will explain how Vala differs from other programming languages and use examples to demonstrate interesting aspects of Vala such as D-Bus integration, asynchronous programming, non-null types, and interoperability with other languages using GObject introspection. 2009-07-06 15:45-16:15Published 4 months ago

gnome-shell video 4/4
Fourth video shows how the applications view can be expanded. Entering a search term changes the applications results list, which can then be navigated by paging. Dragging an item from the list causes the workspaces to slide back in, returning the overlay to the default state and allowing the user to drop the item on a particular workspace. The user then moves the newly launched application to a new workspace and switches to that workspace.Posted 4 months ago
