Candidate platforms?
by Daniel Vainsencher 08 Mar '06

08 Mar '06

Dear SqF board candidates. While we know all of you to some extent (some more than others), we dont know you as elected representatives. If you can write a few words about what goals the board should accomplish, and how you're going to help those happen, it would be helpful for at least this Squeaker in his difficult decisions ahead...

Squeak communicating with Linux robots
by Jason Rogers 04 Mar '06

04 Mar '06

I just read an article in Linux Magazine about Linux robots (http://www.linux-magazine.com/issue/65 and http://www.linuxrobots.org). The robot is connected to a network via an onboard WLAN card. You SSH into the computer on the robot, execute some C code (which hooks into the robot's libraries called 'librobot'), and botta-boom-botta-bing -- the robot moves. I thought it would be neat to write a layer that would translate E-Toy scripts into C in order to enable kids to control a robot from Squeak. However, I have no clue how to "export" E-Toys scripts. Maybe that is the wrong tack altogether. Perhaps all I need is a plugin or FFI that would interface with the librobot C code. Am I on the right path, or is it more complicated than that? -- Jason Rogers "Where there is no vision, the people perish..." Proverbs 29:18

Squeak in more than 8000 teachers and kids laptops, need for i18n
by Hilaire Fernandes 04 Mar '06

04 Mar '06

Hello all, For the second years, we will propose Squeak in the latptops the teachers and junior high school students receive each year in the French adminstrative area of Landes (SW of France). More info about this Laptop operation at http://www.landesinteractives.net/ (English version at http://www.landesinteractives.net/default.asp?cnf=2|) Each year the notebooks are remasterized, this year we would like to propose more Squeak components of interest for education as KEDAMA, ODECo, Connectors, etc. However we need to internationalize and translate in French these packages. The CDDP des Landes and the FSUG/ESUG can do this but we need to synchronize with the adminstrators of these packages because we need to modify the source code. In SqueakSource, I only found ODECo and its administrator Takashi Yamamiya. What about KEDAMA (Yoshiki Ohshima?) and Connectors? Who are the managers of these packages, we need to check with you to propose the modifications for mainstream. We have a page to keep notes http://community.ofset.org/wiki/CD_Squeak_pour_Landes_Interactives Hilaire Fernandes

Plopp and Teddy (was: An interesting presentation and discussion, maybe still is)

This >idea originated in the masters thesis of Jana Hintze at the games group >in Magdeburg (see >http://isgwww.cs.uni-magdeburg.de/games/projekte/kindervorlesung/jive.html). Both of these approaches are very easy to use, so they appeal to me :) And the method of "inflation" is very similar between the two. In the Croquet version of this system, there are frequently errors when the painted object doesn't have a strong continuous outline, and the Teddy flavor, which is still in Squeak 3.8 Wonderland, is fun, but not as easy to manipulate as I would like and has no export function. At the moment, I am using an external modeler (Art of Illusion) to create 3D models, but I would like to find an open-source 3D paint program similar to Tattoo ( http://www.terabit.nildram.co.uk/tattoo/ ) to complement this. One of the projects on my "someday" list is to make a specialized version of the Squeak Wonderland Pooh-painting that is easier to interact with and has better import/export capability. Or maybe develop a whole new version of this, similar to Takeo Igarashi's old Chameleon, only with Java and OpenGL for platform independence. As long as I'm daydreaming, it would be really nice to have cleaned up, usable versions of Takeo Igarashi's SmoothTeddy and Squirrel, which includes creating a model, painting it, and animating it, only maybe rewritten in Croquet ...

referencing objects (newbie)
by Eddie Hillenbrand 03 Mar '06

03 Mar '06

Hi everyone, I just downloaded Squeak two days ago, so far I love it. I want to use it to teach my little sister how to program. But first I need some help figuring out the basics. How do I refer to objects I create? If I create, for example, an EllipseMorph how can I refer to it in a Workspace, so I can send it messages using "do it"? I've figured out how to open a Viewer and change the object's name, but if I try to send it a message in a Workspace I get an "Unknown variable" error. Thanks, Eddie

Mirroring SqueakSource repositories?
by Andreas Raab 01 Mar '06

01 Mar '06

Hi Guys, Does anybody know if it's possible to basically mirror SqueakSource repositories? What I'm looking for is something where I can have a downstream repository that (for simple purposes of added reliability) mirrors an upstream repository. While this can be done manually, it's kinda tedious to do this for a number of repositories so I'm interested in an automated way of doing this. Any ideas? Thanks, - Andreas

[ANNOUNCE] Connectors 2.3-187 released on SqueakMap
by Ned Konz 01 Mar '06

01 Mar '06

This long-overdue release fixes several outstanding reported bugs with Connectors 2. It hasn't been tested with 3.9 alpha, but it fixes the following problems in 3.8: * attachToSelectedSpec changes from Michael Latta (Mantis bug# 1525) * use of defaultColor for object initializations (Mantis bug# 1476) * addition of image-fixing code so that loading into a 3.8 image doesn't delete methods (Mantis bug# 1331) * allows Etoy scripts on Connectors to be triggered on #mouseUp (#mouseStillDown still doesn't work) Sorry I've been a bit absent... -- Ned Konz ned(a)bike-nomad.com

Object Explorer stopped working
by William Harford 28 Feb '06

28 Feb '06

My object explorer has suddenly stopped working. I have not touched the Object explorer and I am not sure exactly when it stopped working. The Object explorer displays but when I click the arrow to expand the tree it shows nothing. Is there a way to reload the object explorer? Thanks Will
