PhET Progress Report

Dec 13, 2007

An online version of this report is available here.

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

Translation

· Received and posted Greek translation for soluble salts

· Synchronization of translations with main site

1. Simulations cannot be rebuilt and redeployed without testing

2. Translations should be made available online quickly

3. To run, need to update main jar. To translate, need to update all flavor jars.

· Synchronization utility identifies and resolves discrepancies between jars online and local translations

· Also added a test to ensure new key set is compatible with old

· Still need to add an upload task, and test

Rotation

· Latest version

· Organized to-do’s into Unfuddle

· Platform can be flung (in rotation)

· Cleaned up introductory panel

· Acceleration is not necessarily centripetal under user-controlled motion

· Bugs fly off

· For detailed changes and to-do’s, please see the table at the bottom of this report

Moving Man/Ramps/Force1D

· Finished 1^st draft of to-do list

· Initial draft combining force1d and ramps

· Improvements for energy model

· Added objects to play area

· Added friction

Build Process

· Test new build and deploy process (from John), looks good

Phetcommon

· Cleanup: parsing numbers from localized strings

Upcoming Work

· Rotation/Torque

· CCK

o Organize requests into unfuddle

o Bugfixes

· Continue developing Moving Man, Force1D, Ramp with new common libraries, (with Chris/John)

· Moving man basically complete, start on Ramps next, and use that as the basis for Force1D

· Generate better reports from Unfuddle/identify ticket times in unfuddle

Unfuddle changes for Rotation Simulation

Inner radius change doesn't move ladybug	Accepted
Angular momemtum not conserved	Accepted
Reset all doesn't correctly clear acceleration and velocity vectors	Accepted
Show a Pause Icon in the play area when simulation is paused	Closed
Applied brake force should stop the rotation platform more quickly.	Closed
Simulation shouldn't start recording until the user presses 'go' or moves something in the play area.	Closed
Record/Pause at the bottom should read Go/Stop to match other chart controls	Closed
Any interaction in the play area should unpause a paused sim	Closed
show "paused" text in play area instead of pause icon	Closed
acceleration vector should be non-central under manual control of platform angle	Closed
bugs fly off	Closed
platform should continue rotation when flung	Closed
The "reset all" button should probably go back to the initial 'stopped' state, and not start recording immediately.	Closed
torque: cleanup control panel	New
torque: box around graph series selection checkboxes	New
add a wiggle me?	New
improve partial side view for platform mass	New
rotation: nonlinear brake force	Resolved
