Applying changesets to selected images only
by K. K. Subramaniam 30 Jun '13

30 Jun '13

Hi, How does one apply a changeset to only a few installations of Etoys in use in the field on machines with diverse OS (Linux/Mac/Win)? Suzanne Guyader uses Etoys to teach art to children and teachers not all of whom use XO. The brush sizes in Paint tool needs to be reverted to 1/3/7/13/26/50 for non-XO images only. I have attached a changeset that I created for this purpose but I don't know how to roll it out on diverse machines. I suppose I could create a command line script that applies this changeset and updates the image/changeset files but the steps involved are too complex for children. Is there any easy way? TIA ..

Re: [etoys-dev] [squeak-dev] Squeak on tablets
by Casey Ransberger 18 Jun '13

Hi Gary. So I think the hardest part will really be agreeing on what gestures mean what. I've run Squeak, Cuis, and Pharo over iOS (thanks mostly to John McIntosh and Bert Freudenberg,) and I'd recommend avoiding that platform for what I'm guessing your purposes might be. App Store cuts us off at the knees for everything except "end-user" applications, which basically shoves anyone wanting to write a program and share it with other people (young or old) into the $99:year iOS developer program; not a suitable arrangement for either revolutionary thinking or early education. Android, whichever version: I've heard folks have made some progress here, but maneuvering around all of the Java infrastructure isn't my bag, (rather just compile and run C code) so I haven't even tried it. I'm looking forward to this whole Ubuntu Mobile thing. At least that's just Unix at some (accessable) level in a mobile device. Here's what I'd do right now if I had an income: Raspberry Pi model-B rigged up (somehow!) to a Pixel Qi dual mode transflective display. These aren't too expensive, can do the natural light ebook thing as well as the backlit usual thing. The prototyping kit is around $300 last I checked, but it gets a loooooooooot cheaper when you buy in bulk (these are basically XO screens.) So stick one of those underneath a capacitive touch screen kit. Now autocad yourself a nice enclosure, and have Shapeways 3D print it. Put the bits together, USB wifi module optional! Make your own interrim DynaBook, except Shapeways has way better materials than cardboard! Sounds involved, I know, but if we went to KickStarter with it... maybe someone would want an unencumbered BSD/Squeak-based tablet, eh? (Cough, half the people here.) CC Etoys dev just because. :D On Jun 17, 2013, at 2:42 PM, OpenSlate ChalkDust <openslateproj(a)gmail.com> wrote: > As some of you know I spent quite a bit of time getting nowhere trying to get Squeak running on top of FreeBSD in a tablet form factor.The situation has changed considerably, in that the world has gone tablet crazy.

What has been done to adapt the three-button mouse squeak expects to have to a fingertip input?

discussion at yesterday's ed meeting
by Kathleen Harness 02 Jun '13

Hi Avigail, I found my way into the meeting, it was just Rita and me but we had a good conversation. I have an idea for iPad Apps that could showcase several people's projects in individualized Apps so the iTunes store would have a series of Etoys for people to choose among. Free to download. Perhaps the hard part of making Etoys for the iPad could be done once but that what was packaged could be changed pretty easily and the new Apps could go up over time as the projects were ready and a developer had time to swap things in and out. Examples: Etoys Points of View: Avigail's Simulations Etoys Points of View: Rita's Projects for Illusions Etoys Points of View: Steve's Mathematical Projects Etoys Points of View: Kathleen's Games and Puzzles etc Perhaps there are other people who would like to do something like this too. I chose the phrase Points of View to reflect our history and connections to Viewpoints Research Institute. The projects for each POV could be added to the Etoys Examples already available so the 26 that are there now would be the same for each App but the 25-50 new ones would be there too. In this way we would be able to show how many ways there are to use Etoys but the sets would be coherent according to the author's POV. My projects act and look quite different from the others, as do yours, Steve's, and Rita's. Since I really don't know what is involved from a developer's point of view, I just offer this as something for discussion. Kathleen
