Grace Hopper Celebration Codeathon for Humanity

The Codeathon at GHC2011 is intended to introduce participants to rapid development of FOSS applications in a collective coding setting.

Suggested Codeathon Projects

​OpenStreetMap integration

Leveraging the synergy of Kate Chapman's presence, and more generally, of OSM's participation...

Potlatch integration

There is already a basic integration of ​Potlatch (web-based OSM editor) into Sahana Eden (currently we have an 'Edit in Potlatch' button on the toolbar in the fullscreen map which opens the relevant area):

• ​http://127.0.0.1:8000/eden/gis/map_viewing_client
• ​http://127.0.0.1:8000/eden/gis/potlatch2/potlatch2.html

  controllers/gis.py potlatch2()
  views/gis/potlatch2.html
  

This could use updating & having more customisation for the Humanitarian context (there are some presets here: ​http://pierzen.dev.openstreetmap.org/hotpotlatch2/potlatch2.html) & tighter integration with Sahana.

OSM Importer UI

• There is an import stylesheet for .osm files: static/xslt/import/osm.xsl
• This currently has hard-coded mappings between OSM admin levels & Sahana admin levels
  • * ​http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#10_admin_level_values_for_specific_countries
• A custom controller should be written
  • provide a UI to the user to select their country from the dropdown which pre-populates the mapping fields for manual verification/adjustment
  • process the results of this to pass new variables back to the stylesheet:
    • ​http://pub.nursix.org/eden/s3xrc/vita.modules.s3xrc.s3rest.S3Resource-class.html#import_xml

      resource = s3xrc.resource("gis", "location")
      template = os.path.join(request.folder, resource.XSLT_PATH, "osm", "import.xsl")
      resource.import_xml("uploaded_filename.osm", template=template, mynewvar="xxx")
      

• The Stylesheet needs updating to act on these vars when found

A nice further refinement would be to provide a UI to select a BBOX & optional filter to pull down the .osm file via ​XAPI

• Initially this could be manual text box entry of BBOX/filter
• Then add a Map-based BBOX selection & dropdowns for the filter (which prepopulate the real dropdowns for manual verification/amendment)

Translations Admin Panel

Use Cases

• Admin wants to update /languages on their running instance with current version from Pootle
• Admin wants to be able to do offline translation of main language file(s) (either using native web2py UI or using a PO-based tool like Virtaal)
• Admin wants to be able to translate additional custom strings in this instance (either using native web2py UI or using a PO-based tool like Virtaal)

Tasks

• Add a page to controllers/admin.py to handle Translations.
• Update the InstallationGuidelines with any new optional requirements (such as translate toolkit).
• Gracefully give nice error messages if the translate toolkit isn't installed.
• Update UserGuidelinesLocalisation

Export PO file

• Dropdown to select which language
• Button to call ​web2py2po to convert the .py file to a standard PO file for the user to download

Import PO file

• Upload Widget which calls ​po2web2py onaccept to convert a .po file to a Web2Py .py file stored in the languages folder
  • Use the same filename prefix or prompt?
  • Do a merge

Update Pootle

Provide a set of admin scripts (bzr post-commit hook?) to update Pootle with any changed strings as a Merge.

CAP: Common Alerting Protocol

• Receive CAP messages from an external CAP source.
• Provide a form for originating CAP messages.
• Send CAP messages to subscribers, retrying on failure.
• Write a Facebook app to receive CAP messages and post them on one's wall.

SAARAA: Situational Awareness and Rapid Assessment Application

This was started as an Android app at RHoK #3. That version uploaded data to a very simple Heroku back end.

​http://www.rhok.org/problems/saaraa-situational-awareness-and-rapid-assessment-application

As a follow-on to that project, allow the app to send to an Eden back end.

• Add an appropriate model.
• Handle receiving uploaded messages from non-logged in users -- provide a code they can use to log in later.
• Display the messages by category and time.
• Allow commenting on the messages (e.g. adding updates about handling the messages).
• Allow sending a message back.
