PhET Progress Report

October 1, 2009

An online version of this report is available here.

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

Motion Series

� Added 12 fixes, latest version is 1.03.45, partly in collaboration with John

� Improvements for the-ramp, forces-and-motion, moving-man

� Fixes based on Trish�s recommendations before her classroom use

Moving Man

� Posted updated version on main site as 1.26

� Synchronize horizontal axes

� Set chart to take up all vertical space by default, see #1782

Misc

� Applied for IntelliJ license renewal

o They granted us another license, and asked that we update our banner, see #1805

� Worked with John on KSU installer

� Improved support for stage area and transforms in MyCanvas (press S during Ramp Simulation)

� Discussed 3D issues with Chris, Jonathan & Wendy over email

� Posted Ladybug Motion 2D as 1.00 on tigercat, after resolving some bugs NP pointed out, see #1806

Additional Work

� Updated scala projects to use Scala 2.8-style imports

o all upcoming IDE support is focused on 2.8

o Scala 2.8 beta should be out sometime this winter, right now IDE developers are mostly working with nightly-builds

o I�m keeping PhET�s Scala code 2.7-compatible until there at least a 2.8 beta

� Experimented with Eclipse plugin nightly builds

o Many features missing, but able to edit, build, run, debug scala sims, some support for navigation

� Did a full git checkout of phet�s svn (trunk + tags + branches)

o Took about 4 days

o Empty updates are about 2x as fast (15 sec vs 30 sec)

o Full history stored on disk, easy to visualize

o Easy to branch, could be useful if we use branches to support re-releases of sims with common changes

o Easy to checkout previous revisions

Upcoming Work

� Ramp simulation, see to-do list

� E&E graph should have record/playback, use Scala recording controls.

1. Noah provided a mock-up, see email

2. Rewrite this component in Java?

� Discuss MyCanvas layout implementation with Chris, John, Jonathan

1. Still experimenting with it

� Posted sim dependencies, and sims for common libraries and a report for ramp in particular

1. Decide which of these sims should be reposted, or whether we'd like to investigate the source code for changes before investing in repost + retest.

2. Chris recommended making common text change logs available to testers

� Motion Suite: need to discuss Robot Moving Company games with NP

� CCK - new Physics implementation, testing and performance analysis (with Sam M)

� JMonkeyEngine/Xith /3dzzd/Flash/Papervision3d/Away3D/Feng Gui

� Make it possible to redeploy sims with common changes without retesting the sim when we redeploy again

� New JProfiler?� Copy of Flash?
