PySide: Python for Qt And Automatic Bindings Generation

  • Marcelo Lira dos Santos - marcelo.lira@openbossa.org - setanta on #maemo
  • Intended audience: application developers/platform developers
  • Talk type: presentation
  • Abstract/description:
The Python bindings for the Maemo Platform provided by PyMaemo are an all-time favorite among the Maemo developer community. Python must keep up with the recent addition of Qt to the Nokia offering for Maemo developers.
PySide are the Python bindings for Qt framework developed by INdT (Instuto Nokia de Tecnologia) [1], and recently released under a LGPL license. The PySide [2] bindings target not only the desktop but were conceived to provide Qt for Python on the Maemo platform.
Qt being a huge library, the task of creating bindings for any high level language must be automated as much as possible, while retaining the developer ability to adjust details to satisfy the particular target language demands. To tackle this problem, a binding generator for Python was developed based on QtScript Generator from Qt Development Frameworks. Developers of bindings for other Qt-based libraries could also benefit of this automated generation scheme.
This talk will present PySide, describe its characteristics, show its current status on Maemo Platform and where the project is headed to. The binding generation tool will also be explained, as well as the common problems that arise when wrapping C++ libraries to high level languages such as Python.

Marcelo is an active developer of PySide and PyMaemo projects at INdT and has been involved with Maemo apps development since N800. Nowadays he is working with automatic binding generation for C++ based libraries, like Qt.


From corporations to communities: responsible and effective engagement

  • Randall "Texrat" Arnold, fabricator at cynicalsigns dot com, http://tabulacrypticum.wordpress.com
  • Intended audience is Nokia PR; Nokia Maemo team; Maemo developer, tester and superuser community; other interested parties
  • Talk type : best practice/lessons learned presentation
  • Abstract/description
The presentation covers the following subject areas: general best practices in the area of corporate/community relations and how they apply to Maemo, as well as possibly a post mortem of lessons learned vis a vis community outreach from both Maemo and user perspectives (via interviews).
This will not be a "what Nokia did wrong" as much as it is a clear, appropriate guide for future public relations in the murky world of commercial enterprise meets open source development; a path forward

Midgard2: Content repository for your tablet and the web

  • Author: Henri Bergius, henri.bergius at iki dot fi
  • Intended audience: Application Developers
  • Talk type: presentation
  • Abstract/description
Midgard2 is an Open Source Content Repository providing an objectified view to the data and services surrounding it. At the basic level it abstracts the database access (SQLite, MySql, PostgreSQL) but this is only where it all starts. Serialization & replication, managing own storage objects, multi-process access to data are all covered. The fully object-oriented (GObject-oriented) API allows you to focus on the data, not the database syntax, regardless of what programming language you are working with. Midgard's content repository services allow you to easily write applications that keep their data synchronized between tablets, web and user's desktop computers.

Tracker: Dial M for Metadata

  • Ivan Frade <ifrade@gnome.org>
  • Intended audience: application developers/platform developers
  • Presentation
  • Abstract/description
Tracker is a freedesktop project (with GNOME roots) included in the maemo platform for the first time in maemo5. In fremantle it is a simple index engine with support for basic metadata. For harmattan Tracker takes a great leap forward becoming a central storage for *user information*. The important data for the user (contacts, messages, multimedia, ...) will not only be stored in an application independent way, but also in a "linkable" format. This enables a new user experience: it makes it possible to integrate contacts everywhere, mix IM/email/twitter history of a contact, and so on.

In this presentation, Application developers can see how data is linked and obtained from Tracker to enrich their applications; platform contributors can learn how to integrate new information sources.

ContextKit - context awareness for Maemo and everybody else

  • Author: Marius Vollmer <marius.vollmer@nokia.com>
  • Intended audience: application developers/platform developers)
  • Type: presentation
  • Abstract

A lot of information is available from sensors and other sources that can make applications more 'aware' of the situation that a mobile device is in. The current location is an obvious example.

A new ContextKit collects these information about the environment of a device, combines many of them into something more abstract and exports it all in the form of simple key/value pairs to applications and other consumers. A long list of 'standard' properties is defined.

This presentation introduces the ContextKit to application and platform developers.

High-resolution image processing on Maemo devices

  • Author: Alexander Bokovoy - alexander dot bokovoy AT nokia dot com
  • Intended audience: application developers/platform developers
  • Talk type: presentation
  • Abstract/description

N900 is the first Maemo device with high resolution camera. While making photos with camera is an obvious use for it, resulted images are stored on the device and can be used by applications for other purposes as well. Mobile devices like N900 are quite constrained for image processing needs and special work is needed to minimize consumption of memory and processing resources.

The talk will cover camera application development in Maemo 5 and plans for common set of image editing functionality for high-resolution pictures in Maemo 6. We hope to create open and extensible platform-wide solution which can help all developers to better utilize constrained resources on mobile devices.

Test framework tool for Maemo devices

  • Author: Carlos Aguiar - carlos.aguiar@indt.org.br, Fabio Almeida - fabio.almeida@indt.org.br, Luiz Nagata - luiz.nagata@indt.org.br and Jyrki Sippola - jyrki.sippola@nokia.com
  • Intended audience: users/platform developers
  • Talk type: presentation/demo
  • Abstract/description:
Companies usually develop their own tools for test and monitoring consoles directly into their products but these applications tools, in general, do not go out of production place and are not deployed for platform developers and final consumers. These solutions are closed and just for company use. The open source community provides many tools to test different functionalities like keyboard, display, wi-fi and so on, but they do not work together as an integrated solution.
The proposal is to integrate different functional tests into a test framework tool for Maemo devices. This framework will be able to communicate with different test applications, control them, gather information and report status results, helping developers and users to identify problems, perform reliability tests and gather statistics. Also, it will be possible to extend this framework to support new test types.
For demo presentation purposes the framework will run the following functional tests: keyboard, camera, audio, display and wi-fi.
