[Etoys] Plan for DrGeo screencast to explain its features
by Hilaire Fernandes 07 Aug '08

07 Aug '08

Hello all, I would like to produce several screencast to explain the DrGeo features. I have written a first plan about what to produce at http://community.ofset.org/index.php/Screencast_DrGeo I would love to get some feedback about content idea aswell technical suggestions to produce good quality screencast (given I am constrained to a linux host). Thanks Hilaire -- http://blog.ofset.org/hilaire

[Etoys] Display bug after windows resizing
by Séverin Lemaignan 06 Aug '08

06 Aug '08

Hello, Maybe this problem has been already adressed, but I face a strange bug when I choose to set the display to the "Scaled virtual extend" mode and I go back to the standard, full-resolution, screen: Squeak turns black and white (cf screenshot). Do you know how I could get back the colors ? (I'm running the Etoys image, rev 153 from 28 july. The VM is Squeak 3.10 of 22 July) Regards, Séverin

[Etoys] Fun with DrGeo II Smalltalk script
by Hilaire Fernandes 06 Aug '08

06 Aug '08

A small video exposing what can be done with this new coming feature of DrGeo: http://squeak.ofset.org/drgeo/script-tangente.ogg By the way, although we hit there senior high school curriculum with this example, it is at heart programming as thought by OLPC project and how to make it accessible and fun for teachers and learners. More to come... Hilaire -- http://blog.ofset.org/hilaire

To my mind, rotation and scaling *are*, or should be, considered persistent properties of the morph, and thus the fact that they are not preserved when the morph is saved, stand-alone fashion, in a .morph file, is a bug -- minor, but still a bug. But note that stand-alone saving in a .morph is not part of the "etoys interface", which is why it's hidden off in the debug menu, unavailable to "eToyFriendly" users. The lone persistence mechanism that is formally supported in the etoys interface for kids is the project-saving mechanism. -- Scott

[Etoys] Jiggling the mouse
by K. K. Subramaniam 03 Aug '08

03 Aug '08

Hi, Yesterday, I watched a 7-year old girl use Etoys to assemble a face using ellipses and rectangles. Sometimes, the rotation center had to be changed from the default for embed ops (e.g. ears). I had taught her to bring up the halo menu and and use the red menu button to turn on the direction handle. She discovered that moving the rotate button leaves behind the direction handle and preferred to use it. When the rotate button is used, the direction handles appear and stays on even when the rotation ends with the original heading. My initial reaction was to make a note to file a trac ticket. But then, watching the ease with which she used the rotate button to bring up the direction handle and move it around, I realized this jiggle gesture comes easily and naturally than shift click for children. Jiggle the dup button to get a sibling, jiggle the color button to get a property sheet and so on. BTW, I made a one-liner fix to use simple drag (instead of shift-drag) for moving direction handles. If others can try this out and find it useful, I will file a ticket for its inclusion in Etoys. Subbu
