[Etoys] Fun with Smalltalk at hight school
by Hilaire Fernandes 10 Jan '09

10 Jan '09

Computer are good at dynamic stuff, I love to mix interactive geometry and analytic calculus. With DrGeoII it is becoming so much fun. I would have love to play with that at high school. See this post, in French only, but if a brave soul can translate it in English I will be great. http://blog.ofset.org/hilaire/index.php?post/script-drgeo Hilaire -- http://blog.ofset.org/hilaire

[Etoys] Strange problem with file access
by Hilaire Fernandes 10 Jan '09

10 Jan '09

I am sugarizing iStoa, it comes with its own virtual machine and image. The image comes with Magma and I am conducting tests on the XO. I see a strange behavior: When I start iStoa from the Sugar application dock, I can not open the Magma database from iStoa. It complains it cannot open the database file. I try to follow what is happening from the debugger, and it seems to be related to StandardFileStream>>primOpen:writable: FilePlugin? However the path to the Magam databse file is fine and correct. Now when I start iStoa from a terminal activity with the command: ./Activities/iStoa.net.activity/bin/istoa.sh I can open the database without problem. The database is in ./Activities/iStoa.net.activity/resources/Magma I am wondering: are there restrictions on file i/o when an activity is started from the Sugar application dock? -- http://blog.ofset.org/hilaire

[Etoys] [ANN] Sugar bundle iStoa.net v. 8.12-alpha1
by Hilaire Fernandes 09 Jan '09

09 Jan '09

Hello, Not sure where to announce it, so here it goes. I am releasing an alpha bundle of iStoa.net for Sugar. It is only a demo of iStoa.net to play with the learning activities. There are about 40 etayages (kind-of scaffolding), and all in all more than 150 exercises. The following piece of Smalltalk code executed and printed in a Workspace of the iStoa environment will give you the exact number of exercises: (IFIEtayage allSubclasses inject: 0 into: [:n :each | n + each basicInstance stepNumber]) Learner activity recording and guidance is not enabled or easily accessible from this bundle. It will requier too much fine tuning, explanations and test from me right now. It is however present in the package. The bundle can be downloaded directly from this url: http://gforge.inria.fr/frs/download.php/14090/iStoa.net-8.12-alpha1.xo Of course feedback regarding the activities is very welcome. The iStoa.net website is www.istoa.net, and its contents is still in French only. PS: Btw I have not solved the problem with file access restriction from a sugar bundle.

I would vote for the inclusion of this into the Etoys V4 >image (though it touches more methods than I imagined). Ha. It was a viral bug. I literally found the same code snippets in slider, button code and movie player morph. People had copied the bug verbatim to all those places. Copied also was logic in each menu to hide the target setting item under certain circumstances. This was clearly writen to work around the bug. The naive way of dealing with the problem hid the target setting item most of the time. I first fixed the bug just for sliders. As time passed I added the other places as I found them. And by the time I got around to the Etoys version of the repair I had quite a list. The history is there on mantis several different bug reports. Look for them under Squeak or AllProjects. Search for sliders or targeting. Make sure to look in the closed reports. I probably started most of them. Looking for reporter 'wiz' can help narrow things down if necessary. > > I haven't tried it with Nebraska, but the targetOffset/targetPoint >change works with it, right? Good question. I never stumbled across Nebraska in my fixing. If its broken now the methods used for the fix could be applied. I spent lots of time with the problem and got to know it pretty well.

[Etoys] Setting slider targets.

Setting slider targets. Hi all, I am glad to see that you included the star repair in etoys 3.0 and now 4.0. My heart feels glad that children will be able to play with them. So here is the next repair still needing doing: Right now you can get a slider from supplies. You can set its action. You can set its maximum and minimum extent. You can give it arguments. The one thing you cannot do is set its target. The bug has been found and fixed in 3.9 and 3.10. A while back I made a changeset to fix target setting for 3.8 and etoys.' It's on mantis. http://bugs.squeak.org/view.php?id=6521 0006521: Target setting doesn't work for buttons and sliders The only way to find out if it still works is to check it out. If you have problems with it let me know and I will help. Targeting makes it possible to design a slider the way you like it. Duplicate it. Then use the duplicate for a totally different object. This is very handy for rapid development. Hth. Happy New Year. Yours in curiosity and service, --Jerome Peace

[Etoys] "Help" button "not used anymore" in Etoys-dev 4.0 ?
by Séverin Lemaignan 01 Jan '09

01 Jan '09

Hello, Maybe I missed something on the mailing list about that, but when I click on the "Help" button in the menu bar with the etoys-dev-4.0 image, I get an error message "not used anymore", thrown by "QuickGuideMorph initializeIndexPageFrom:". This doesn't occur with "etoys-4.0.image". Is it the expected behaviour? Thanks! Séverin
