GeoGebra Developers Working Group, Wed, 30. August

This working group welcomes everyone who wants to help with coding for GeoGebra.

Chairs:

Markus Hohenwarter (Johannes Kepler University, Austria), markus@geogebra.org
Michael Borcherds (Queen Mary's Grammar School, UK), michael@geogebra.org

Groups Tuesday

• GeoGebra Web & GWT: GWT compatible codebase
• Interface & Equation Editor: consistency, editor in Java or JavaScript? 
• Numeric and symbolic algorithms: implicit curve intersection, efficiency
• Code Profiling & Optimization: HPROF

Wednesday

• GeoGebra Web refactoring: one code base
• 3D algorithms for parametric surfaces, intersecting curves, 3D input device: webcam 
• Non-Euclidian view for spherical / hyperbolic geometry: using 3D code 
• Barycentric coordinates, triangle centers 
• Interactive Whiteboard: Corinna has a list
• Profiling, Bug Fixing: JVM Monitor 
• Locus Equation: JAS -> Reduce
• Proving & symbolic computations 
• USB Logging, Kinect, Phoenix
• Equation Editor: interface & spreadsheet
• Moodle: connection to GeoGebraTube, exercises
• Spreadsheet / Statistics enhancements 

Possible threads

Development tips and tricks:

• Eclipse tips
• General Q&A about the structure of the code

Housekeeping:

• Performance (file loading!)
• Code Structure / Cleanup
• Automatic testing (unit tests, integration tests, etc.)
• Multithreading 

Necessary changes to integrate

• 3D    
• GGM

into GeoGebra. 

New Ideas / Features:

• Logging (eg Go!Motion, Phoenix, Kinect, Arduino, .NET Gadgeteer)
• Equation Editor
• Adding Video to GeoGebra 5.0
• Scripting / Programming
• Adding a "kids'" programming language to GeoGebra (Python, Logo, Scratch, JavaScript, etc) 
• Java: Build-in scripting engine 
• Simplified 'versions' of GeoGebra?
• GeoGebraPrim: do we need simpler Tools, large buttons? 

Misc: 

• Session on GIT
• Mirror server network / load balancing
