FOSDEM 2010 Announcement

FOSDEM 2010 will take place at at the Université Libre de Bruxelles, in Brussels on Saturday 6 and Sunday 7 February 2010.

This page is for organizing GNUstep's participation in the event. This includes the organization of a developer meeting the Friday before FOSDEM.

Organizers

  • Lars Sonchocky-Helldorf (lars dot sonchocky dash helldorf at hamburg dot de)
  • Richard Frith-Macdonald (richard at tiptree dot demon dot co dot uk)

Who will attend FOSDEM

One of the main reasons people attend the event is that you can meet, and talk directly to, other developers, whom you would otherwise meet only virtually (on mailing lists, emails, newsgroups, IRC etc.). We expect many lead developers and contributors to be present, so if you have never met them, you shouldn't miss this occasion!


The following is a list of people of GNUstep fame who have confirmed (or denied) that they will be able to join us at the GNUstep meeting at FOSDEM 2010:

Dev-Room Presentations and Events

The room at out disposal will be AW1.117 (capacity is 31 seats; in the building "AW"), -- on Sunday 2010-02-07 from 09:00 to 17:00

Call for participation

We are looking for people who want to give a talk, moderate a discussion, hold a hand ons (practice) / hacking session or organize a code sprint. Please send your proposals to GNUstep discussion list, the organizers mentioned above or - if you've got a wiki account - enter them right here. At first a title, a short summary, proposed duration and a preffered time slot would do, so we can start scheduling as soon as possible.

deadline for filing is Sunday 2010-01-03, deadline for the papers is Sunday 2010-01-10

Note: The FOSDEM organizers strongly recommend a granularity of 15 minute blocks. So if a talk is just 15 (lightning talk), 30 or 45 minutes long - fine! But we should have 15 minutes breaks between the talks so that the visitors have enough time to find a seat and the presenters have enough time to get ready.

Schedule

Time Slot Author Title / Abstract Kind Slides
Sunday, Feb 07, 2009
09:00 - 09:45 Developers "Developer's Meeting" meeting, discussion -
09:45 - 10:15 Nikolaus Schaller "Simple WebKit: a simplified WebKit compatible implementation in pure Objective-C 1.0"

Simple Webkit is a reimplementation of major parts of the WebKit Obj-C API (WebView, WebFrame etc.). Internally it uses pure Obj-C. This keeps requirements towards the compiler low (there isn't Obj-C++ support for all embedded architectures). Another simplification is that it is completely based on the rendering engine of NSAttributedString and NSTextView instead of having its own. This keeps the code and binaries small for a full (X)HTML 4 compatible WebView (approx. 1 MByte). The presentation describes the internal architecture and the status of CSS and JavaScript integration.

status, architecture, demo, discussion t.b.d.
10:15 - 10:45 Nikolaus Schaller "Learnings from porting QuantumSTEP to different Linux Handhelds (e.g. Openmoko)"

This talk will present recent experimental results from QuantumSTEP on several embedded devices. QuantumSTEP is a full mobile application suite (e.g. PIM, dialer, browser etc.). It is based on an experimental variant of GNUstep called mySTEP. Many optimizations have been applied to learn what has to be considered for embedded devices with tight memory and processing power constraints.

demo, cross-compiler, performance, optimization, discussion t.b.d.
10:45 - 11:00 Nikolaus Schaller "ocpp-2.0: a preprocessor approach to translate Obj-C 2.0 extensions to Objective-C 1.0 for (older) platforms"

With the introduction of OS X 10.5 Apple had defined an gcc-extension for Objective-C which brings many interesting features to the language: garbage collection, properties, synchronization, fast enumerations, dot-notation for getters and setters, code blocks, etc. Although Apple provides their extensions back to gcc, integration is slow because it has to be tested against all other gcc features and also needs special considerations for different target architectures. So let's dicsuss another approach: write a preprocessor that maps the new Obj-C 2.0 features back to any existing Obj-C 1.0 compiler (plus some library calls if needed). This should allow to faster follow new developments of the language. The talk offers for discussion a flex/bison grammar for Obj-C 2.0 and some strategies for translating the new features.

lightning talk, discussion t.b.d.
11:15 - 12:00 Fred Kiefer (moderator) "Towards GNUstep GUI 1.0: what we need to get there and how to achieve this within the next year." moderated discussion t.b.d.
