[Etoys] Custom eToys image in the OLPC?
by Mauro Esposito 11 Jun '09

11 Jun '09

Well that's the question.. Can i put a desired image of eToys in the OLPC and load it? I'm wondering this because i want to put an image with some packages loaded (i.e. NetMorph and it's dependences, wich i'm using in Windows) into the Sugar o.s. of an OLPC. I don't know if it is possible but i want to know because if i can't, i'm wasting my time working with images that will be unaccessables! Than you. Mauro

[Etoys] broken links
by Angel Arias 10 Jun '09

10 Jun '09

hi! sorry, but i got a new question! first of all, i'd like to say that i'm preparing a five days workshop about "active essays" [in granada, spain] next week during a film festival called "cines del sur" [ http://www.cinesdelsur.com/ ]. the aim of the granada film festival "cines del sur" ("cinemas from the south") is to disseminate and promote films made in the countries of the so-called geopolitical south. so, in the workshop, we are going to use OLPC-XO laptops and squeak etoys software in order to create an active essay about jose val del omar [spanish inventor and cinema visionarie, 1904-1982] [ http://www.valdelomar.com/ ]. once the workshop is finished, we are going to donate these laptops to children from a poor area in north africa or south america [not decided yet]. i'm preparing some projects for the workshop using etoys in a OLPC-XO machine. some etoys projects use sound and movies. i'm saving the projects and their multimedia files in a USB device. i woud like people to take USB devices at home and transfer the content to their computers to keep working there. the problem i found is that the link between projects and files break when i transfer the content to [i.e.] a macbook [i always keep folders hierarchy]. i think etoys uses absolute paths to find files so my question is: is there any chance to keep links between projects and multimedia files unaltered when changing the platform? thank you for reaching this point of this long email. and sorry for my awful english. i do my best! angel.

[Etoys] NetMorph
by Bert Freudenberg 08 Jun '09

08 Jun '09

Hi folks, prompted by Martin Bleichner's request for more powerful networking in Etoys I had a look at NetMorph again. If you don't know it yet, see http://swikis.ddo.jp/NetMorph Amazing collaborative stuff our Japanese friends did there! I tried to load it into a current Etoys image. After some fiddling it kind-of works: Here, I can control the Ellipse's movement locally. When I press the "warpOver" button it "warps" to a different machine but I can still control it from my local machine. Pressing the "warpHome" button brings it back. That's so awesome! Making multi-player games with this is almost trivial :) I had to code the warp-scripts textually because the "net morph" category in the viewer remains empty. Maybe someone else could figure out why. This appears to be the only major problem. Normally, all this can be done with tiles. To install, first open the "SqueakMap package loader" and let it update itself. Close it. Then, file-in the attached NetMorphEtoys4a.st which will churn for quite a while installing lots of packages and end with an error when trying to add the japanese translations. At that point, I ran the remaining initialization steps by hand ;) I put the resulting image here: http://dev.laptop.org/~bert/etoysNetMorph.image.zip If you duplicate that image you can run two instances on one machine which works fine. They find each other automagically. Now, this adds about 1 MB to the regular image. If we could make it work reliably I'd say that's probably worth it. OTOH it pulls in a lot of stuff (e.g. the Komanche web server, SOAP client and server etc) that probably could be done more simply. In particular, under Sugar it should not use this home-grown infrastructure but the Telepathy framework. In any case this would be a great addition to Etoys. Maybe someone knows a bright student who could make it work? - Bert -

[Etoys] Etoys Based Activity - FreeCell Sugar interactions
by Milan Zimmermann 05 Jun '09

05 Jun '09

Hi Bert, I finally did some investigation into Squeak interaction with DBus and Datastore. I went through the classes that implement the DBus and Datastore interaction. This is some great stuff! Among others, if I understand this correctly, your Squeak DBus client framework could, for example, allow to use Squeak to write a KDE or gnome panel applet? But that is an aside. As Step 1, my goal was to figure out how to save a project in Journal from a set of commands in Workspace. Going to the debugger, I found that if I open a project in Etoys, and in a workspace, and do Project current storeOnServerWithNoInteractionThenQuit. the project is saved in Journal, and on restart, Etoys must have read the Journal saved project because it shows any changes I have made in the project. It seems that the core method called from storeOnServerWithNoInteractionThenQuit that interacts with Datastore is SugarDatastoreDirectory>> #writeProject: self inFileNamed: fileName fromDirectory: localDirectory So I tried to do the the same (Project current storeOnServerWithNoInteractionThenQuit.) from a workspace in the FreeCell activity. When performed, it does write to the Journal, but upon restart, I get an exception that appears a DBus object cannot be found - picture attached. Could the difference be it because Freecell, on startup, does not setup some DBus interaction? Well in any case, I am looking for some help trying to figure this out. I was thinking about these steps I'd like to achieve: 1) Command in Workspace that saves the FreeCell project on Journal. I seem to be able to do that, but on fairly high level ( Project current storeOnServerWithNoInteractionThenQuit.). Eventually I'd like to get it done with more but lower level commands. 2) Sure and understood way to open the saved Journal Project in FreeCell. (So far within Etoys it seems to work, but I have little understanding of it. In FreeCell it does not) 3) A command or set of commands in workspace, which wil allow to Rename the FreeCell project (and save on Journal under the new name) 4) Ability to start using the black Launcher ribbon on top, with the standard Etoys project name a project stop widget that would call the commands from 1 and 2. . 5) More interaction such as copy/paste on Journal Do these goals and order make sense? I will try to maintain a blog about what I am playing with. http://mzimmerm.blogspot.com/2009/05/how-to-install-and-run-sugar- activity.html I am unfortunately frustratingly slow and sometimes fail to respond for a long time, combination of lack of time and experience in this area (Squeak/DBus/Sugar), but will keep going... Appreciate any help. Milan

Re: [Etoys] [Sugar-devel] Collaborative game using Etoys

(please remember to reply to the list ...) Well, that sounds like you do not even have Sugar running? That would be the prerequisite to do anything with it. - Bert - On 02.06.2009, at 19:29, Martin Bleichner wrote: > Hi there, > > I tried to find my way around telepathy and busses. > as far as I understood it form the article 'Etoys for one laptop per > child' etoys can run within sugar. > Telepathy provides the communication interface and squeak dbus > bingings allow me to make use of that from squeak. > I am still miles away from a way to start. > > Would someone be willing to share some (squeak specific) example > code with me so I have something to start with? > > Thanks, > Martin > > > 2009/6/1 Martin Bleichner <bleichner.martin(a)gmail.com> > Hi Bert, > > I actually don't have any intention on how I want to implement it.
