saving squeak projects - a bit of troubleshooting needed
by David Wells 16 Feb '06

16 Feb '06

I'm a technology teacher in a K-8 school in Chicago, and am teaching Squeak to a bunch of 4th- 8th graders right now. Has anyone else had any difficulties getting kids to save their projects to an outside server? My students are able to successfully publish their projects about 90% of the time, but it's the other ten percent that's the killer - when they open their previously saved projects, they get nothing but an error message and advice that they should probably click "abandon". As of now, most kids understand that the program is on the experimental side, and are willing to start over again, but I can see frustrations mounting as the projects get more complex. A related question: once a project is published using the "publish to a different server" option, is there any simple one-click option to save the updated version to the same location? Or do they have to click on "publish to a different server" again and re-select their folder on the server? Thanks for any help in answering these - David Wells ps. We are running Squeak on iMacs that are using OS 10.2 or 10.3, and saving to a G4 file server, if that helps at all.

Re: [Squeakland] generate a movie?
by Arvind Grover 15 Feb '06

I had asked a similar question before, and Kim ran it by the Squeak development group. No easy answers. I have been using the free software Wink (http://www.debugmode.com/wink/) to capture animations to Flash movies. It is based on screen-shot captures, but allows for very nice annotations during movies. -----Original Message----- From: squeakland-bounces(a)squeakland.org on behalf of Randy Heiland Sent: Sat 2/11/2006 4:10 PM To: squeakland(a)squeakland.org Cc: Subject: [Squeakland] generate a movie? The presentation I gave yesterday to about 25 Indiana school teachers on Squeak went reasonably well. More to come. But for starters, one teacher who had actually played with Squeak a bit asked if it was possible to capture movies within Squeak. I told her no, I didn't think so, but wanted to verify this. I know the Object Cataglog/Multimedia has the mpegplayer. I realize that doing movie capture, in general, can be a bit tricky - with multiple formats, quality and frame rate params, etc., not to mention a possibly large file as output. Still, it would be nice to, say, capture frames in playfield (start/stop) in some "standard" movie format. --Randy _______________________________________________ Squeakland mailing list Squeakland(a)squeakland.org http://squeakland.org/mailman/listinfo/squeakland

This call for papers might be of interest to our group. Cheers, Darius ___ From: Ian Parberry <ian(a)unt.edu> Date: Feb 13, 2006 12:45 PM Subject: CFP: ACM JERIC Special Issue on Game Development in Computer Science Education Call for Papers: ACM JERIC See http://www.eng.unt.edu/~ian/jeric2006.html for full information. Although game development classes have existed in Computer Science programs for well over a decade, there has been a recent surge of interest in applying game development to a full range of courses in colleges and universities nationwide. The purpose of this special issue of JERIC is to share the experiences of faculty involved in the development and management of game development classes with the wider audience of this Journal. Contributions will be reviewed on the basis of technical quality, relevance to the topic, significance, and clarity. About ACM JERIC The ACM Journal on Educational Resources in Computing is an electronic publication providing access to high quality, archival resources suitable for use in support of computing education. Resources include scholarly articles with wide applicability and potential impact as well as multimedia and visualization resources, laboratory materials and other materials of practical use in support of learning in the computing sciences.

Soliciting Feedback on Kedama
by lkao＠ucla.edu 10 Feb '06

10 Feb '06

Hi Everyone, We'd like to hear from those of you who have tried Kedama! If you used the online tutorial, was it useful? What changes would you make? Also, if anyone has used Kedama to make a new example, create a variation on any of the existing projects, or used it in the classroom, we'd love to hear about it. Any comments are welcome; please let us know what you think! Thanks, Linda

broken project?
by Randy Heiland 10 Feb '06

10 Feb '06

http://www.squeakland.org/project.jsp?http://www.squeakland.org/fun_projects /Sqfest_2004/Fishland.003.pr Is it possible this project is broken? When I load it, there's some funky "extras" (holder, etc) and I'm unable to change the male/female populations with the sliders. Or maybe it's just operator error. I was checking out some of these online projects before pointing a bunch of Indiana science teachers to the site this afternoon. Thanks, Randy

of animating, rotating, scaling, undo and the future
by Kim Rose 08 Feb '06

08 Feb '06

Dear Squeaklanders, I send this note on behalf of myself and the "etoy developers" who created and continue to support the original etoy system, some of whom continue to evolve the system to its next level. A few of you have pointed out less-than-ideal experience(s) when creating multiple frame animations where you or your child/student have wanted the object they initially paint to change its size as part of the animation. You have noted that duplicating and changing the size of the original object can lead to unexpected results. (We have observed this when we conduct workshops as well.) Our team has engaged in much discussion (a group of us hold weekly computer-based "conference calls" where we discuss support and development issues) over this issue. Due to the nature of Squeak's underlying architecture, especially in regard to the way the system handles the scaling of objects, it is our recommendation to you and your children that when creating multiple objects you wish to animate, IF you wish to see a size-change for that object, that each object be painted and saved individually, in whatever size desired. You should avoid using the duplicate feature in such cases. If you follow this procedure you will be ensured to get the result you are seeking. We highly appreciate your feedback on this, and other features (or lack of them). Another recent example is the discussion of the "undo" button on the navigator bar. While we may not have the people power to implement an "infinite" undo on each action (the ultimate desire) in this version of the system, please be aware that our knowing that you desire such action is a good thing. (We'll soon be "pushing" an update to Squeakland which improves this "undo" buttons abilities and provides some feedback as well.) We will strive to work this and other such suggestions into future releases of the authoring enviornment. I think the community realizes that the etoy system currently downloadable from the Squeakland website grew out of a demo and is the efforts of a small team of researchers (not product developers) doing most of this work as a labor of love. Some features (undo in the nav-bar, for example) were put in as a 'placeholder' for something we want, ultimately, and are in a first-start position and for one reason or another have only gotten "so far" and then work on that particular feature paused, perhaps because another feature required the attention of that person at that time, etc. Our limited 'people power' has caused starts and stops on features within the system (text and audio chat being another you are familiar with). Please know we are hard at work to evolve the current "etoy" system into something more robust, with scripting and other features suited to middle and high school students as well. As we are developing this system, we are listening to you! Thank you for your continued trials, curriculum and project development, and your continued feedback to us. It is very important to our current and future work. -- Kim

fixed dist follower
by Randy Heiland 07 Feb '06

07 Feb '06

Oh merciful Squeakers, Is there a nice trick to have one sketch follow another by a fixed distance? I'm aware of the 'turn toward' tile, but I don't want the follower to ever catch up to the leader. Some simple scheme for: follower(x,y) = F[leader(x,y,heading)] Thanks, Randy

Re: [Squeakland] suggested 1 hour squeak exercise for various student age groups?
by Darius Clarke 06 Feb '06

06 Feb '06

Hi Daniel, I'm taking 8-15 yr. olds through Kim Rose's "Powerful Ideas" book (see the Squeakland site). They seem to like it. I'm taking the 11-15 yr.oldsdirectly to charting, after they master motion, since they need charting for a "project based learning" health project. I have some 5-7 yr. olds whom I'm just letting paint with Squeak. I'll see what they can do, but I'll introduce concepts gradually. Cheers, Darius
