Code Sprint - what's that?

A code sprint is usually organized by a group that is using an open source project and wants to see something done. They fly the developers to a single location and feed them for a couple of days with the necessities of the hacking life (internet, caffeine, electricity). The communication that happens from face to face hacking usually lasts the project for a year or more. You see this a lot in projects like Drupal etc...

Venue

More than 80 attendees are expected!

Motivation and Direction

A day, a code base, and your imagination?

Projects can use the time and venue for organizational discussions, development roadmaps, and group resolution of thorny issues in their code bases.

Geometry

DATE: SUNDAY 25 OCTOBER

Time: 10am - 4pm

Venue: Intersect, Level 12, 309 Kent St

This sprint will be held on Sunday 25 October at a different venue (Intersect). We ask everyone attending to add their name to the list below as we are limited to 12 people. First come, first served.

Coordinator:

  • Ben Caradoc-Davies

Attending:

  1. Ben Caradoc-Davies
  2. Jody Garnett
  3. Andrea Aime
  4. Andrea Antonello
  5. Silvia Franceschi

Goals:

  • Progress ISO 19107 / GML 3D geometry collaboration (OSGeom). See <java-collab@lists.osgeo.org> for more.

Plan: Some subset of Markus Schneider's proposal:

  1. DONE - Remove all topological and spatial analysis methods in the interfaces from the SVN for now, so we can focus on sanitising the model.
  2. Add factories. I would like to add two factories similar to the ones in the deegree 3 SVN:
  3. Add a basic implementation that is just a bean representation without operations. We could finally start to add JUnit tests then.
  4. Add GML parsers/exporters. I understood that one may want to keep this aspect out of the repository, but I don't see how we could test the difficulties in representing GML geometries (e.g external xlinks) without this. It also would make setting up geometries for testing much easier. Maybe we could keep the GML parsing/exporting isolated from the rest of the code.
  5. Of course we would take on the operations subject again, when we find consensus here.

Live DVD

Coordinator: Cameron Shorter

Attending:

  • Ricardo Pinho
  • .

Virtual attendees can join us at: irc://freenode.net#foss4g

Goals:

  • Brainstorm ideas for improvements to the LiveDVD

    • Documentation guidelines
    • Desktop layout
  • Target other distribution media

For specific ideas, add them to our issue tracker here: http://trac.osgeo.org/osgeo/query?group=status&component=LiveDVD&order=priority

OpenLayers

Coordinator:

Attending:

Goals:

OpenLayers bug fixes. Describe any additional goals here.

To prepare for the sprint, please create/update tickets (http://trac.openlayers.org) for stuff you want to work on, and add "foss4g09" in the Keywords form field of the ticket.

MapServer

Coordinator:

Attending:

Participating through IRC (#mapserver):

Goals:

  • Work on the 5.6.0 release, including:
    • Testing the current beta/release candidate
    • Bug fixes
    • Release of 5.6.0-RC1 (depending on how beta4 went)

Mapbender

The target group for this (non-coding) sprint are software architects, geoportal operator, service broker, service provider, data provider.

Coordinator:

  • Arnulf Christl

Attending:

  • Person 1
  • Person 2

Goals: This group will not code software but rather have informal discussions about the road map and new requirements of the software Mapbender. Some work needs to be done to define and more importantly better communicate the unique selling point of Mapbender. It is currently the only Open Source software that ships with of the box features to deploy, maintain and operate large scale geo portals using nothing but browser interfaces.
