[Etoys] quitting from etoys
by Ties Stuij 13 May '08

13 May '08

Quitting Etoys on an XO takes 1min30 sec with our old Epaati setup, because etoys does some saving on shutdown. To me this is not a feature, but actually diminishes functionality, because there's no way to quit without saving. I know there's a magic incantation involving holding shift or something, but I'm talking from a user/kid perspective. The attached patch changes this behaviour to just quitting the image using the squeak quit primitive. Is there something to say for this approach? /Ties

[Etoys] Literate Etoys
by karl 13 May '08

13 May '08

I've started a attempt to make Literate Etoys inspired by Literate Programming and Active Essays. This to make it easier to clarify the intent of the different scripts, document the project and hopefully help users or students get a overview. It will have made a automated way of inserting ScriptEditors and text fields into a ScrollPane or a BookMorph. The first script attempt adds a ScriptEditor for each script to a Playfield. Then I realized that the ScriptEditor got pulled of the Playfield and into the world if I opened the script from the Viewer. Now I wonder if there is a way to keep two version of a ScriptEditor in sync, one in the Playfield or documentation and one in the world ? Ideas and suggestions are welcomed Karl

One of my students made a fabulous etoys project on a monitor with 1680 by 1050 resolution. Is there an easy way to scale it to a smaller monitor? Thanks in advance - Mark

[Etoys] OLE Nepal distribution pics
by Ties Stuij 28 Apr '08

28 Apr '08

Last Friday we distributed XO's to our (pre-) pilot schools. Remarkably we didn't yet post anything to our blog about it, but I know you all are much more interested in the piccies. The coolest ones i feel are the ones of the exited and concentrated girls prodding the XO's for the first time at the end of the set. The second link shows additional pictures related to XO's but leaves off distribution pictures that don't have xo's explicitly in the picture (this is more a rule than actual reality, but it does affect the set-content conciderably). laptop distribution: http://www.flickr.com/photos/80049722@N00/sets/72157604771101410/ xo pics : http://www.flickr.com/photos/80049722@N00/sets/72157603977140085/ /Ties

by Chris Leonard 28 Apr '08

28 Apr '08

I stumbled across this, on the ELDIS (http://www.eldis.org/) community site. It seemed relevant enough to cross-post to games, etoys and devel lists. An OLPC presence would seem perfectly logical and potentially very beneficial. cjlhomeaddress(a)gmail.com http://wiki.laptop.org/go/User:Cjl +++++++++++++++++++++++++++++++++++++++ Registration for the 2008 Fifth Annual Games for Change Festival is now available! Please join us at Parsons the New School for Design in NYC for our annual event bringing together non-profits, educators, game designers and activists of all stripes to explore the growing movement and emerging field of games for social change.

[Etoys] Part II of my advocating article about Squeak/Smalltalk programing for education
by Hilaire Fernandes 26 Apr '08

26 Apr '08

In this series of articles, I will highlight the advantages of using Squeak/Smalltalk to develop educational software. At some point and based on my experience, I will compare with other development languages. The focus of this article is for educators and developers interested in software programming education applications. In these articles, don't expect to learn about Smalltalk/Squeak programming, my goal is simply to give an overall picture, based on real experience. Feedback is of course very welcome. In this article I will discuss about the Smalltalk image concept and its consequences. http://blog.ofset.org/hilaire/index.php?post/2008/04/24/Why-you-could-consi… -- http://blog.ofset.org/hilaire -- http://blog.ofset.org/hilaire

[Etoys] Squeak activity about angle
by Hilaire Fernandes 23 Apr '08

23 Apr '08

A simple pedagogical activity about angle for primary school. You need to have DrGeoII installed in your Squeakland, so you can open the project from your browser. Alternatively you can use DrGeoII packaged for your OS: http://wiki.laptop.org/go/DrGeo#I_don.27t_have_an_XO.2C_can_I_use_Dr._Geo_I… Then you drag and drop the activity project file into it. Does it sound clear? Hilaire -- http://blog.ofset.org/hilaire

[Etoys] Custom event translation
by Bert Freudenberg 23 Apr '08

23 Apr '08

Korakurider, I just saw the custom event translations in the new German po file. It looks as if the help text is not translated? Also, there seems to be a typo for "keyStroke" which you spelled "keystroke". The relevant methods are senders of #addCustomEventFor:named:help:targetMorphClass : if anyone wants to take a look ... - Bert -
