[Etoys] Re: Images updates (it was Re: [Trac #1066] Can not set sound and visual effect forBook)

Hi, Offray, To obtain an image that contains the latest version of the FrontPage project, together with its corresponding project files, download: http://etoys.laptop.org/src/etoys-image-and-pr.zip You can then load updates to bring that image abreast of the latest code changes. To get the latest versions of the DemonCastle tutorials before they've made their way into an XO build, download them manually from http://tinlizzie.org/olpc/tutorial/.

[Etoys] Re: [Trac #1044] Clock settings in Etoys failed.
by Scott Wallace 16 Mar '07

Thanks, Tess. Both of these bugs are now fixed by update 1237clockFixes-sw, which also cleans up other aspects of the Clock's halo menu.

[Etoys] Translation eToys image
by Juliano Bittencourt 14 Mar '07

14 Mar '07

Hi, My name is Juliano Bittencourt and I'm participating of the Brazilian early tests of the XO laptop. We will implement these tests with 400 laptops on a small school in Porto Alegre (South of Brazil). All children and teachers in the school will have their own laptop. In our ideas, Squeak will have an key part in our pedagogical praxis. But we are facing some small problems in the first classes we are doing with children. The main problem is that the eToys image is in english. So I want some orientation of how to translate the etoys image and how to make this work available for others in the project? Thanks, Juliano

[Etoys] Interactive Story Telling and Etoys
by Offray Vladimir Luna Cárdenas 12 Mar '07

12 Mar '07

Hi all, First a little of background: It seems that these days, most movement on education and Squeak is happening at this list :). Squeakland has been quiet for a while and Extremadura Small-land uses Yahoo Groups and not community owned infrastructure for communication (I have not a YahooID and I don't want to be forced to have one to belong to a community list). I was using Small-land Extremadura's image of Squeak for my initial classes and courses because of the documentation available in Spanish for my students. But seeing the traffic on the lists, the potential impact of OLPC in education and the continuous development of this image over say Squeakland or Small-land, I'm planning to use OLPC etoys image for my courses and classes at least at the beginning (before using the excelent BotsInc image from Stephanne Ducasse). I'm planning also to use this image in Schools with computer labs where children can develop content for the OLPC even if our government still has not commitment officially with the project. So here come the questions: * I have attached a small sketch of a book. It's a story from one of the most famous Colombian poets and author of a long list of children stories. It was originally sketched on Extremadura image, but now I want to change the layout of graphical elements for the etoys image (with lower resolutions ballon text overlaps images all the time). - ¿It's possible to say where the help balloons are going to be located?, ¿can they be made semitransparent and control the level of transparency? - ¿Any pointer to documentation of how can I made a drawing follow some invisible path on another drawing? * ¿There is any plan of unification/feedback for this work with the Squeak-land, Small-land images? Would be nice to have a active developed image that can be used on different kind of machines, from OLPC to Desktops with different size resolutions and content that can be adapted visually to them, without much redoing. I will try to test the project on the prototype of the physical machine send to us this week and will see how adapts to the screen. Cheers, Offray

[Etoys] [Fwd: Squeak MIDI output with Linux / ALSA]

Folks, May be we can include this at OLPC.
