PySide: Python for Qt And Automatic Bindings Generation

  • Marcelo Lira dos Santos - - 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,
  • 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

I am a former Nokia employee (Alliance factory and DSNM trade customer logistics) who was a principal on the US launch team for the N800. As Quality Engineer I managed the delivery of 200 devices to CES 2007 and ensured quality on devices delivered until their production relocation to Mexico. I became one of the first Nokia employees to reach out to the new community of tablet software developers and have continued in a voluntary representative role. I also tested internal applications such as the enterprise support suite (including VPN) and field tested the N810 WiMAX Edition tablet. I also developed a prototype mobile auditing solution using the internet tablets. Today I still cover the internet tablets and their applications at

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.

Developing applications using Plasma

  • Artur Duque de Souza - asouza AT kde DOT org / morpheuz AT gmail DOT com
  • Intended audience: application developers
  • Talk type: presentation
  • Abstract/description
KDE4 brought a new concept of desktop called "Plasma" where everything is a "live object". To achieve this, a library called libplasma was created and this is a very powerful library that enables any application to create modular and rich UIs. During this presentation I'll talk more about libplasma and how it can help the developer to create more attractive and rich UIs easily.

Hackathon: Integrating Canola with Fremantle

  • Author: Eduardo Lima (Etrunko)
  • Intended audience: Application Developers
  • Talk type: Hands-on/Hackathon
  • Duration: All Saturday/Sunday long
  • Abstract/description
The idea of this session is to get a reasonable number of people interested in integrating Canola with the new technologies introduced in Fremantle, mostly Tracker and MAFW, together, so we can trace a plan and start getting our hands dirty.
Some Canola components were conceived aiming to provide alternate solutions for some Nokia closed-source libraries and others that were not available by the time we started the project (mid-2007, back then we only had the N800 with Bora/Chinook). That's why we created our own media scanner (lightmediascanner+canolad) and media engine (atabake). Now I think it is time for us to evolve to the new and open solutions provided by Fremantle, yet keeping compatibility with "legacy" platforms, such as Diablo.
People interested in developing plugins for Canola and/or developing using EFL/PyEFL are more than welcome to join us.

Designing Emulators for Mobile Devices

  • Marat Fayzullin - RST38h on #maemo
  • Intended audience: application developers
  • Talk type: presentation
  • Abstract/description
Computer system emulation has been known for years. Recent revolution in mobile hardware makes it possible to run usable emulators on mobile devices, but some problems still remain. Limited performance, lack of proper controls, and widely varying screen sizes make it difficult to provide users with proper experience. This presentation will describe how the above problems can be worked around.

WebKit Community: How It Works

  • Ariya Hidayat, ariya dot hidayat at nokia dot com
  • Intended audience: application developers
  • Talk type: introduction and workshop
  • Abstract/description
WebKit has evolved over time into one of the most compelling HTML rendering engine currently in use. As an open-source project it stands out because of its size and because of the special collaboration between volunteer developers and companies.
This presentation is not so much a presentation in the classic sense but planned as an introduction to the team rules of the WebKit project, e.g. how to create patches, ask for review, get in contact with the developer, etc. It will be followed by an extended question and answers session that should cover the most important and mots common questions.

Maemo Platform Security: Consepts, Architecture, Implementation

  • Elena Reshetova -
  • Intended audience: users, application developers, platform developers
  • Talk type: presentation
  • Abstract/description:
The purpose of the Platform Security in the Maemo platform is to protect the owner of a Maemo-powered device from getting her personal, private data and passwords from being stolen and used for malicious purposes, to prevent a malware from misusing a device and incurring costs on user, to prevent a user from accidentally breaking the device and to make the platform meet the requirements set by such third party software that requires a safe execution environment.
The main design goal is to have all this accomplished without any significant penalty in terms of performance or usability, by using established open standards and having as much of the implementation open-sourced as possible. Another goal is to minimize an entry barrier for 3rd party programmers by reusing the existing Linux programming environment and introducing only needed additional features.
The presentation will cover the main concepts, architecture choices and implementation of the Maemo Platform Security.
