Android on the XO tablet?
by Casey Ransberger 30 Aug '13

30 Aug '13

I just caught this: http://androidcommunity.com/olpc-xo-tablet-retail-availability-expands-2013… Do we have the VM working sufficiently under Android to consider deploying to this platform? (I'm aware that we aren't touch-UI ready yet, and I'm specifically asking about the VM Etoys uses.) I guess I had assumed it would use a Fedora variant like the XO laptop. Which suddenly has me wondering if the laptops will start shipping with Android at some point. TIA -- Casey Ransberger

Hi, Can someone in France/Europe get in touch with Ms. Suzanne Guyader and trace performance issues in Etoys (see below)? I live in India and the large timezone is proving to be a hindrance. Local help is appreciated. [Mdm. Suzanne Guyader is a senior art teacher in France who guides art teachers/students use Etoys as a medium for research in art. She uses Etoys 5 on Windows but some of her pupils may use Linux/Mac] Any help is appreciated ..

I placed the information you provided me on sites ‘Art and Etoys ' and ' Art and Etoys of Squeak ‘ http://community.ofset.org/index.php/Pistes_utilisation_Etoysof Hilaire Fernandez.. Thistemporary access has the advantage of preserving the current presentation of Etoys environments for many users not involved in artistic research, without frustrating others. This relieves me of a weight because I really felt a lack. To continue the list of my frustrations, I do not know if it comes from my Pc that are too modest but I'm surprised that access to many interesting projects of the Showcase are practically inaccessible. Loading time is became intolerably long because of the number of projects submitted. Sometimes it takes hours to get the last of them.. This is unfortunate because it is rewarding and informative for everyone to have access to research so varied.. But there is perhaps a computer impossibility. Always grateful for your availability regards suzanne

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

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.)

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

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

Etoys live CD?
by Casey Ransberger 28 May '13

28 May '13

It seems insane that it's so hard to get a Squeak VM installed. Maybe we need something like Etoys but geared towards the things IT administrators care about and identify with! Especially the word "no." I've worked with a lot of IT people who say "security" when what they really mean is "it would take work to evaluate the threat model and I don't feel like doing it so no." One approach I've found which sometimes works is to make everything so easy for them that they feel guilty about saying no. Has anyone thought of doing an Etoys live CD? There would be nothing to install, Etoys can already save projects to other machines, right? Just a thought. Doesn't really assuage security concerns, but those are mostly B.S. anyway. Does make IT person mostly irrelevant (you wouldn't need their help. Just the knowledge of how to enable CD or USB booting and access to the reset button, and the live media (CD DVD or thumb drive.) If you used a DVD you could probably keep like a million projects on the disc too.

Re: [etoys-dev] Etoys in Javascript
by Harness, Kathleen 26 May '13

Jecel, 97%, sounds good to me. There are early projects from 7 or 8 years ago that are not as well done as the later ones. As I became a better teacher, so too did my student's projects. I do not understand all the steps a visitor to our site would need to take to get one of those projects to open. The fewer steps the better, the fewer roadblock hurdles to get over the better especially for young children or cautious adult beginners. Have a good weekend, it is sunny and cool here.

Yes, that is far more important than any specific Etoys feature in my opinion as well. In the Squeak community, after Edgar De Cleene it is likely that I have been the most vocal about keeping old stuff working. Bert Freudenberg wrote: > would converting the projects be okay? Meaning, suppose the "Javascript Etoys" > couldn't read the old project files directly, but there was a way to export a project > from Squeak Etoys into another file that could be imported by Javascript Etoys, > would that be sufficient? That sounds like an interesting plan. I had only though about putting all of the conversion work in the new system, but it is true that some things are easier to do inside the original system. It might be the case that getting 100% of the projects converted is really hard but 97% is reasonably easy. It would be a good idea to find out, specially if the 3% turn out not to be among the most important projects. -- Jecel _______________________________________________ etoys-dev mailing list etoys-dev(a)squeakland.org http://lists.squeakland.org/mailman/listinfo/etoys-dev
