[edit] Hackathon: Integrating Canola with Fremantle

  • Author: Eduardo Lima (Etrunko)
  • Intended audience: Application Developers
  • Talk type: Hands-on/Hackathon
  • 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.
Why??
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.

[edit] Building for Mer

  • David Greaves
  • Intended audience: application & platform developers
  • Talk type : Presentation/demo
  • Abstract
Since Fremantle Extras applications will eventually be submitted to the Mer builder it may be a good idea to introduce it. We use the openSuse Open Build Service; a GPL service that provides an emulated, pristine (yes, I'm looking at you autobuilder and scratchbox), dependency driven build environment. I'll talk about the processes around Mer builds, access controls, managing integration with our DVCS (git), acceleration tricks and generally how to make good use of things you find lying about on the web.
  • Additional Information
Live web link to OBS would be good.
  • Author bio
David is the Mer build mentor; he's been a solutions architect at a major telco for several years but still (kinda) knows how to code. He's a passionate believer in the commercial viability of OSS. Previous contributions include kick-starting the git documentation & establishing wikis for Linux RAID and MythTV. He runs linux everywhere.

[edit] Handheld Glom: Easy database applications

  • Murray Cumming <murrayc at openismus dot com>
  • Intended audience: application developers
  • Talk type: Presentation
  • Abstract/description:
Many custom Maemo applications just need the user to navigate through some data and enter new information. Glom lets you quickly throw together a database structure and UI layout, providing a Maemo UI with no coding. You can then use Python for anything more complicated, though Glom itself already supports features such as related records, related fields, related choices, field lookups, calculated fields, and translated UIs.
  • Author bio:
Murray Cumming runs Openismus GmbH in Berlin and Munich. We work on Maemo's development platform and applications and maintain the GNOME C++ API (gtkmm). When we have extra time we work on Glom, gradually getting it ready for real-world use.

[edit] Towards painless and quality translations

  • Dimitris Glezos (glezos _at_ indifex _dot_ com)
  • Intended audience: developers, translators, docs writers, webmasters
  • Talk type: Presentation
  • Material: Slides (pdf)
  • Abstract/description
Most developers agree: "Translations are hard". And while Maemo's localization is already in place, we've got a long way to maximize our efficiency in reaching a global audience. The challenges: lower the costs for developers, minimize maintenance overheads, provide the translators with an effective, easy-to-use interface for submitting translations to their favorite projects (even if they're hosted on git.. *especially* when they're hosted on git).
Transifex is an open localization platform built for and used by communities similar to Maemo such as Moblin, Fedora and XFCE. This talk will present Transifex, discuss the test results by the Mer Project, and lay down the roadmap for the establishment of an infrastructure able to support the L10n process of Maemo.
  • Additional Information
The session will most likely turn into a BoF, bringing together application and platform developers, translators and webmasters/admins.
  • Author bio
Dimitris Glezos is the lead developer Transifex. He led Fedora re-engineer its globalization infrastructure allowing for an explosive growth of community translations. He currently serves as Fedora's Board member and Translation Leader. He works at Indifex, providing enterprise-level support on complex localization scenarios.

[edit] Maemo Platform Security: Principles and Concepts

  • Elena Reshetova - elena.reshetova@nokia.com
  • Intended audience: users, application developers, platform developers
  • Talk type: presentation - Slides
  • 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 principles and concepts of the Maemo Platform Security.
  • Author bio
Elena is a senior security engineer and representative of Maemo security team at the Maemo summit. The current task of the team is development of the Maemo Security FW.

[edit] Telepathy on Maemo

  • Author: Marco Barisione, marco.barisione at collabora.co.uk
  • Intended audience: application developers/platform developers
  • Talk type: presentation
  • Abstract/description:

The Telepathy real-time communication framework is a project to abstract messaging, presence, voice and video functionality, regardless of the underlying protocol. Amongst numerous benefits, this makes the connections available as a D-Bus service which can be shared between multiple applications, rather than limited to single monolithic jack-of-all-trades clients.

The talk will introduce the Telepathy framework, its basic concepts and current functionality. It will focus in particular on: - The Telepathy architecture - How Telepathy is used on Maemo 5 for chat, VOIP calls, telephony calls and SMS messages - How to use Telepathy from your program

  • Author bio:

Marco Barisione started to work on Telepathy implementing file transfer for a Google Summer of Code and for his University final project. After graduating he started to work for Collabora where he worked both on Telepathy and on the GTK+ port of WebKit and he spent the last year working on Telepathy-related components for Maemo. Before falling in love with Telepathy he worked on various other GNOME projects, in particular adding regular expression support to GLib and implementing a new syntax highlighting engine for the GtkSourceView widget.
