[Etoys] ANN: Squeakfest call for presentations
by Timothy Falconer 17 Apr '09

17 Apr '09

Greetings! The official Squeakfest website is now live and ready for you to propose a presentation, workshop, or panel. http://squeakfest.org The dates for Squeakfest USA in Los Angeles CA are August 10, 11, 12. The dates for Squeakfest Brasil in Porto Alegre RS are July 23, 24, 25. Also keep in mind that many of us will be attending nearby WCCE the following week (July 27 to 31). The theme for this year's USA conference will be "Etoys in the classroom." Our overall goal is to show how teachers are using Etoys to teach their full curriculum. Whether language arts, math, science, or more, we hope to showcase the many ways Etoys can help teachers demonstrate abstract ideas easily. If you've got experience teaching with Etoys, we'd love to hear about it, as would the attendees of the conference, many of whom will be elementary teachers. We're also very interested in non-classroom Etoys use, particularly as it relates to OLPC pilots or homeschooling. We'll be adding more information to the website as it becomes available, but for now, the important thing is to get your presentation information to us so we can begin to design the program for our three days together. Please complete and submit the online form no later than June 1st, 2009. Please share this information with anyone you think would be interested in either Squeakfest conference. We hope to see you there! Take care, Tim -- Timothy Falconer Squeakland Foundation http://squeakland.org 610-797-3100

[Etoys] MP3 in Etoys from Uruguay. II part.
by Pato Acevedo 17 Apr '09

17 Apr '09

At this time the Uruguayan technical Office (LATU) is distributing the version of Etoys which allows to play mp3 files. Some teachers believe an automatic update from the control panel could lose this valuable feature. They have asked if is there a manual procedure that will restore this capability just in case? To recompile the VM + plugin is the solution? ¿ May be a .sar file? With this type of questions one of these professors will give their first steps on Smalltalk soon. Thanks in advance Pato Acevedo _________________________________________________________________

[Etoys] Sound in SoaS
by Pato Acevedo 15 Apr '09

15 Apr '09

Hi Guys: > > > > > > The Etoys log file had the known "soundStart: snd_add_pcm_handler: > > > Function not implemented" message. So I added the -vm-sound-OSS > > > workaround to /usr/bin/etoys and then sound in Etoys played fine. > > > Can you to share a step by step mini how to about to enable the sound in Etoys in this way? Thanks in advance. Pato Acevedo P.D.: I'm trying the last SOAS (Soas2-200904062216) and in both my desktop and the Classmate 2 when changing project Etoys I obtain a black screen for a fraction of a second . Am I the only one, or someone else reported this behavior? It is strange because the image is displayed first but then the screen goes to black, "wink" and then reappears the last screen that was flashing before. For example, in the Etoy´s splash screen I make click in the cloud called "Gallery of projects" can to see a thumbnails for all projects but immediately the screen go and return from black. When press the Previous project buttom is the same. _________________________________________________________________ Permanece actualizado con MSN Noticias. Clic aquí http://noticias.cl.msn.com/

Re: [Etoys] [Vm-dev] hampering the desire of the VM and image to visit every object at startup time (multiple times)

We experimented in that direction for OLPC which also is comparatively slow CPU wise, and even slower loading the whole image from the flash disk (which involves decompressing). Mmapping only the pages needed should give a considerable boost. Do we have evidence that an mmap base address of 500 MB works across platforms? - Bert -

[Etoys] Tip: tuning values in tiles
by K. K. Subramaniam 13 Apr '09

13 Apr '09

Hi, I learnt a tip from an eight-year old today ;-). I used to click up/down arrows to change values of a numeric tile - force of habit. Just go click-click-click. A simpler way to change is to hold the left (red) button down when the pointer hovers above the arrows and move the mouse up and down. HTH .. Subbu

Re: [Etoys] Opening a zip file

Oh, I understand now. Sugar on the XO laptop only poorly handles zip files. This is not really an Etoys problem. I'm copying this message to the Sugar list because it might be helpful to others, too. Folks, please cc Rosaura (a teacher from Uruguay) if you intend her to get your reply. Etoys is the only pre-installed activity that can open zip files. When you click on a zip file in the Journal, it opens in Etoys, and Etoys shows a little menu (probably in the upper-left corner): The second menu option "extract all to ..." opens a dialog: This is the folder that the files inside the zip will be extracted to. Choose "tmp" which is near the bottom: Then press the "ok" button. This extracts the files to the folder named "/tmp". To be able to read them, you need to copy them to the Journal. Quit Etoys, and open the "Terminal" activity. Type "cd /tmp" and "ls -l", and then use the "copy-to-journal" command to make the book appear in the Journal: The "text/plain" part tells the Journal that this is a plain text file (because its file name ends with ".txt"). If the book is in a different format, you would have to tell the Journal a different type. For example "text/html" if the book name is ending in ".html" or "application/pdf" if it is ".pdf". Hope this works for you, if not please report back. - Bert -

IMHO it would be good to fix this: Prompt for title and meta data https://dev.laptop.org/ticket/8803 and possibly this: Make launcher project accessible? https://dev.laptop.org/ticket/9282 This reportedly is fixed: Video does not play in Particle Dye project https://dev.laptop.org/ticket/9282 What do we need to do to ship it? Fix the project? Check VM fixes into SVN? Also, are there any fixes pending that are not yet in the update stream? - Bert -
