Thanks Thomas, today is too late in the day for me and tomorrow I will be busy all day. Will try this later on but I´m afraid you overestimated my capacity, I said I am a dummy. These instructions and so many alternatives remind me quite a bit of previous experiences when I could see the same initial screen of the XOs at the schools and start some of the programs but there were lots of things that were not working. Thanks again. WIll let you know if I make any progress.

Frederick, I am not familiar with WIndows. I switched to Macintosh in 1993. Last May a few nice knowledgeable guys tried to put SoaS in my Mac but it wouldn´t work. They concluded SoaS was not yet ready for MacOS. Does SoaS work now in Macs? Has anyone tried it successfully?

How can I do an Http Post in Etoys?
by Steve Thomas 08 Apr '11

08 Apr '11

I am trying (without much success yet) to figure out how to post images to Picassa and post a Blog entry using the Google Data API I am able to figure out how to use HTTP Get script1 | t1 | t1 := HTTPClient httpGet: 'http://www.google.com/search?q=squeak'. self setCharacters: t1 asString That seems to work, but how do I do a POST? (an example project that actually connects to blogger or picasa would be nice ;) Thanks, Stephen

Making an image to fade after going in some directorio for a while and microbloggin bonus
by Offray Vladimir Luna Cárdenas 07 Apr '11

07 Apr '11

Hi all, I'm thinking in somekind of artistic project where I can make a collage of images that advance in a random direction for a while and then vanish after a while. This are small chunks of papers (quotes) and images. I would like any indication of how to make this things fade. In fact the clasical advance and turn did not the trick, because I want to set direction once and after that create this illusion of advancing and fading. Another more advaced thing is trying to get all the text tagged with #LeyLleras in the microblogging sites of identi.ca and twitter and put them to scroll in the bottom of the world. I'm reading now about how to make this two things, but any advice will be greatly appreciated. Cheers, Offray

Methods of Multiplication
by Steve Thomas 07 Apr '11

07 Apr '11

I created a Blog Pos<http://mrstevesscience.blogspot.com/2011/04/ways-to-multiply.html>t that was inspired by Natural Math's "Multiplication Models<http://www.naturalmath.com/multmodels/2.html>" Poster. The idea is to have kids create/record there ideas and observations. They can build, record and publish their models using Etoys<http://www.squeakland.org> . They can also observe and create models in the physical world and record them with a camera for import into Etoys. I did not capture all the models in Maria's poster: ex; Skip Counting, Number Line (Hilaire's Add relative integer<http://www.squeakland.org/showcase/project.jsp?id=7116> a good example), splitting and folding, and fractal (which only work for powers and my example was 2 x 5). Would appreciate other ideas for ways to represent Multiplication Models, thanks. Stephen Images are in a Picasa Web Album<https://picasaweb.google.com/103533856644131866143/WaysToMultiply?authkey=G…> (same one as in the Blog post, just larger image sizes).

Caroline, Here is a Etoys Minute <http://www.youtube.com/watch?v=xMDYf3_uovk> video showing how to animate a mouth. FYI, I created the mouth images with the polygon tool (if you shift click on a polygon, you can see its "handles") the circles in the handle let you move vertices and if you click on a green triangle you can add a vertice. From the menu in the polygon's Halo you can set the lines to curved. The project "The Walkers<http://squeakland.org/showcase/project.jsp?id=7698>" by P. A. Dreyfuss shows a great example of what you can do animating polygons. Note: this project uses some extra code in the polygon object, but it can be done in Etoys by simply placing each "frame" in a holder and animating that way. The advantage of using holders IMO is that the kids can see what's happening more easily. Also you may want to check "Morphing<http://www.squeakland.org/showcase/project.jsp?id=7112>" by Kazuhiro Abe. I think kids will like this and at the appropriate time, with the appropriate guidance they could even write the morphing script themselves. But for now, they could simply re-use the script to create cool effects.

If there was a single way to launch an application that worked flawlessly on all platforms, we certainly would have used it for Etoys-To-Go. Unfortunately, there isn't - and Java is not a solution either, as you discovered, contrary to all marketing. IMHO it's best to just tell the kids which icon to double-click on their machine. They'll do fine ;) That said, it's great to hear you're teaching Etoys :) - Bert - On 05.04.2011, at 05:54, Derek Redfern wrote: > My apologies - I replied to this, but was not signed on to all the lists so I think my message got rejected. > > It's part of a custom system we have set up for ease of use.

Hi Derek As noted below Squeak runs pretty much everywhere all by itself, so it somewhat defeats the purpose to tie its execution to something that might not be everywhere. There are several ways you can do this without bringing something optional like Java into the critical path.
