An online version of this report is available here.

Here’s a pie chart representation of the time distribution.

I started my summer appointment on Monday May 14.

Build Process

· About 8.3 hours this week (including collaboration with Chris Malley)

· Simplified, cleaned, tested build process

· Build process is sufficient for building single simulations

· Click here for a prioritized list of remaining work

Rotation

http://www.colorado.edu/physics/phet/dev/rotation/0.00.10/

· Added a draggable character for the play area

· Added rescaling to graphics

· Attached some readouts to character

· Bugfixes for charts

· See the above link for remaining work.

Time Series

· Factored out code for record/playback of simulation, including controls

· Energy skate park & rotation both use this implementation

· This code should make it very easy to add playback/record to any simulation.

· Need to clean up and continue testing and integration with rotation & energy-skate-park.

Vector Graphics

· Feasibility tests with batik and salamander

Repository

· Standardization of simulations to fit into build process.

· Many simulations have “stubs” that allow building, but will have to be filled in. This can be done on a per-simulation basis or as a batch.

Energy Skate Park

· Post on main site as 2.01

· Chris Keller is testing this and has said he’d probably finish by Monday.

Phetcommon

· Arrow graphics implementation (with Chris)

Statistics

· Added a build task to count simulations and flavors

· This task could integrate with a build GUI to facilitate viewing, building, running and deploying simulations.

Upcoming Work

· Improve build system (with John)

· Rotation (with John)

1. Timeseries

2. Charts

· Energy Skate Park (Keller’s recommendations)
