Flash package in Etoys
by Andreas Raab 28 Apr '10

28 Apr '10

Hi - As promised, here is an update regarding the Flash support in Etoys. I think the story is that there are *two* relevant packages in the 39a repository: There is a "BalloonMMFlash" package which is fairly close to the Etoys "Balloon-MMFlash" category. Looks like the hyphen got removed to make this a separate package. This is close enough to be a good potential ancestor. There is also a "Flash" package in the repository which I think was the version that I had produced for Croquet. My suggestion would be to do something a little weird: 1) Adopt the BalloonMMFlash package as ancestor, merge it[*]. 2) Do an underscore replacement. 3) Rename the category to Flash and adopt the Flash package. 3) Merge that [*]. 4) Publish the new version as basis for Etoys. [*] Merging in this context means to review the diff and to review all changes and ensure that modifications are correct. This serves the purpose of ensuring all changes that have taken place are in the Etoys version. If you would like me to do that, I can, but I don't know how you'd like to deal with the rename of the package in the process. Cheers, - Andreas

GSoC progress
by Ricardo Moran 25 Apr '10

25 Apr '10

First of all, thanks to all of you who helped me in this process, who gave me feedback, who answer my questions, and so on. I'm really happy to be a part of the GSoC program, it's a great opportunity for me, and I'm glad I'm doing it with the help of this wonderful community. I want to remember you that the latest project examples can be found at: http://www.pcs.cnu.edu/~rcaton/ESUG/ESUG.html (I will upload some of these projects to the showcase eventually but IMO this should be the main site where to find my work) and the source code can be found at: http://www.squeaksource.com/GSoCSqueakland.html. Well, it's time to work now :) As Yoshiki suggested I made DataGraphMorph a kind of PasteUpMorph to allow the vectors and points to draw pen trace. But I ran into some problems. The main problem I have is that when I move across the plane the turtleTrailsForm doesn't update correctly. It also doesn't allow drawing beyond the extent of the morph. If I want to make the illusion of an infinite plane, the current implementation of the turtle trails should be modified (at least for my morph). What do you think?

Join us for a sprint week before Squeakfest in July!
by Rita Freudenberg 24 Apr '10

24 Apr '10

Hi all, we are planning to have a one week sprint right before Squeakfest this year, from July, 17 - July 24. I would like to invite you to participate in this event! We plan to book a vacation home on a beach near Wilmington (NC), so that we can stay together, work, and have fun. There are no detailed plans yet about what exactly we will work on in this week. We could for example: - write an Etoys cookbook, a collection of tips & tricks about what you can do within Etoys - develop active essays within Etoys for certain subjects - develop introductional material for kids - have a "code sprint" - ... We are open for your ideas! What we will finally work on also depends on the experience of the participants of the sprint. Please let me know if you are interested in participating, since I have to do the booking soon. We cannot provide any financial support. If you have any ideas on how to get funding for this effort, let me know! Greetings, Rita

programming etoys itself
by Lawson English 23 Apr '10

23 Apr '10

What do I need to do to get started with extending etoys? Specifically, I'm working on porting the NeHE OpenGL tutorials to squeak, and it seems a very kool thing to allow an OGLMorph to be scripted via etoys. Any links to reading material, simple examples, etc? Thanks Lawson

stepping down from squeakland
by Timothy Falconer 22 Apr '10

22 Apr '10

Hi everyone, After much soul searching, I've decided to step down as director of Squeakland Foundation. Since the earthquake in Haiti, my time has largely been spent on our Waveplace education pilots there, which have been very successful and are growing fast. Last night I decided that I need to stay focused on Haiti and our other Waveplace work, that I no longer have time for the additional responsibilities of Squeakland. I leave you in the very capable hands of Rita Freudenberg and whomever the new board decides. I still love Etoys, and will continue to teach it and promote it, though this will now be through Waveplace, not Squeakland. What has been called the "Squeakland Courseware" will now become the "Waveplace Courseware". Same stuff, different website. I will continue to fundraise for courseware development, this will be through Waveplace now. All materials will remain freely distributable. Immuexa, my software company, will continue to host and support the Squeakland website and showcase for free. Squeakland will now be our client, as Viewpoints was before. My very best to the many people I have meet in the last fifteen months. Thank you for your passion, your time, your talent. What a gift to work with such incredible people! Take care, Tim -- Timothy Falconer Squeakland Foundation http://squeakland.org 610-797-3100 -- "Intelligence is what you use when you don't know what to do." ... piaget

Hopefully, that will help translation in the future. There were persistent problems with split strings, lack of placeholders, use of multiple backslashes for interface spacing, line-breaks and something peculiar I couldn't work out, inconsistent capitalization, a severe lack of initial capital letters and final punctuation, missing articles, and lack of context, nevermind a lot of typos and grammatic errors. It's great you posted your detailed notes to our tracker. All: if you have additions, please add them to Clytie's report: http://tracker.squeakland.org/browse/SQ-695 The only apology I have for this is that we started out with an already complex system and added translation support for it. As you noticed, Etoys is much deeper than anything else on the XO, what you see in the UI is just the surface. It has a complete programming environment hidden (but still accessible) below the kids interface. Some of the strings in there are 30 years old - it is built on Smalltalk, the software developed in the 1970s in anticipation of the Dynabook ("A Personal Computer for Children of All Ages"), which OLPC tried to make reality: http://wiki.laptop.org/go/Dynabook The only feasible approach to making this system translatable at all was to almost mechanically mark all strings, and export them. Cleaning them up is an even bigger task, and as you can imagine, a rather "boring" one. Since Etoys [note the new preferred spelling ;) ] is developed only by volunteers currently, they tend to pick other issues to work on ... we'd be *very* happy though if someone took this on. We're also changing our processes to make contributing easier. We'll get there, eventually ;) > I've uploaded the completed translation onto Pootle (overwrite). I tried to commit it, but got the error: > >> Failed to commit file: [GIT] pull failed (['git', '--git-dir', '/var/lib/pootle/checkouts/etoys/.git', 'pull']): error: Entry 'Content.revision' not uptodate.

(If so, where is it, please?) Pootle's rss feed for the pot file seems to be empty: http://translate.sugarlabs.org/templates/etoys/ But the repo has a feed that works: http://dev.laptop.org/git/projects/etoys/tree/po/templates/etoys.pot Direct feed URL: http://dev.laptop.org/git/projects/etoys/atom/po/templates/etoys.pot?h=mast… It's not too informative as there seem to be no diffs in the feed, but at least you'll know something changed. - Bert - > I hope this translation makes it onto XOs soon. :) > > from Clytie > > Vietnamese Free Software Translation Team > > _______________________________________________ > Localization mailing list > Localization(a)lists.laptop.org > http://lists.laptop.org/listinfo/localization

Etoys developer meeting notes
by Bert Freudenberg 19 Apr '10

19 Apr '10

Hi folks, we just had another nice chat on #etoys. This week, Derek O'Connell joined, famed Audio/Video Linux Scratcher :) * Karl (single-mom) and Bert (triple-dad) talked about the Monticello-based updates * Tim brought up release priorities and timing. Fixes, DrGeo and translated Quickguides are going to be in for sure, the rest depends on if someone finds time to work on it. We'll be wiser closer to the release (tentatively between mid-june and mid-august). * auto-updating would be nice, but we do not know how to make it work for all platforms. If someone has ideas, please speak up. * there still are issues with the showcase server, but we need further data. If you notice something odd please report on the tracker. * Derek ("matmo") talked about camera/video issues. Wants to switch Scratch over to the V4L plugin because it has more knobs to twiddle. OTOH, Scratch's CameraPlugin works on platforms other then Linux, so maybe that would be nicer for Etoys? * Derek also suggested WolframAlpha as a possible data source for Etoys, in particular with the visualizations Ricardo is working on. If you have not done so you have to watch this intro: http://www.wolframalpha.com/screencast/introducingwolframalpha.html And then the hour was over. You are welcome to join next week, same place same time :) Full log below. - Bert - <bertf> hi folks <scottwal> hello --> matmo (~chatzilla(a)doconnel.force9.co.uk) has joined #etoys <ritaf> hi <matmo> hi all (Derek O'Connell) --> teefal (~teefal(a)c-66-30-2-7.hsd1.ma.comcast.net) has joined #etoys *** Mode #etoys +o teefal by ChanServ <teefal> hi everyone <bertf> hi Derek <matmo> hi Bert. I finally made it on time :-) --> killring (~killring(a)76.226.178.204) has joined #etoys <bertf> matmo: nice :) <bertf> I just invited folks from #squeak ... <teefal> great <teefal> i'm sitting here in cambridge with adam holt of OLPC <bertf> ah. say hi :) <sm> g'day all --> karlram (~51aa9a7e(a)skylab.immuexa.com) has joined #etoys <bertf> hi karl <karlram> hi <bertf> looks like we're getting some more participants :) <-- ohshima (~ohshima(a)208.49.99.3) has quit (Ping timeout: 248 seconds) <karlram> could you use any of the stuff i did in the monticello etoys ? <bertf> karl: the packaging, sure <karlram> cool <bertf> well did not use it yet <walterbender> hi all <karlram> hi <bertf> hi walter <teefal> adam says hi everyone <karlram> hi <bertf> karlram: we're going to need to apply your partitioning <karlram> ok <bertf> before we can really switch to the MC updates <karlram> you need changesets? <teefal> -- SQUEAKLAND SOFTWARE MEET START -- <bertf> I got one from your image <bertf> teefal: meetingstarted already ;) <teefal> (helps grep the logs) <bertf> karl, did you look at my stuff yet? <karlram> i have not had time yet <bertf> no prob <karlram> wife out of town and im a single mom :-) <teefal> since we have a few more people this week, would it be good to discuss when to target for another general release? <teefal> summer, etc <bertf> karl: I might not have time to work on it until next weekend either. we'll see <teefal> we had earlier discussed mid-june <karlram> mid june seems early <teefal> yes ... mid-august? <teefal> gives us 4 months <bertf> karlram: what do you want to get in for the release? <karlram> we have talked about drgeo <karlram> is that still a go <bertf> yes <karlram> nice <bertf> we have changeset that hopefully will just work <bertf> hilaire was here last week <bertf> he said he also has some fixes <bertf> but in principle this should still just work <bertf> so I'm actually optimistic about an early deadline, not much stuff in the pipeline we have to wait for :) <bertf> teefal: did you file something about the load/save issue? <teefal> my personal priorities: 1) new load & save boxes, 2) new visuals for paint box, 3) new visuals for object catalog, 4) better OOBE (out-of-box experience (aka, home and gallery), 5) auto-updating <bertf> this came up on the sugar list again today <karlram> there a quite a few bugfixes <karlram> teefal : good list <bertf> karlram: I'm aware of about 10 that are ready to go <matmo> I'm looking into any AV issues on Linux versions of Squeak, Scratch & Etoys this week, first on desktop, then on the XO <teefal> are there any "big features" ? <teefal> other than dr geo <karlram> is there a "target" we can give bug fixes <bertf> teefal: don't think so <karlram> matmo: nice <bertf> matmo: great! <teefal> okay, so if this is what we have to do ... what do we call it? <karlram> bertf : monticello ? <teefal> also, is there any under-the-hood stuff? <teefal> like monticello <bertf> karlram: what do you mean by "target" <karlram> to mark a fix ready for a release? <bertf> Monticello should not affect the user experience <teefal> we have "etoys 5 and showcase" <teefal> you want something more granular <teefal> close = ready for release <teefal> resolve = ready for test <karlram> is next release etoys 5 <teefal> http://wiki.squeakland.org/display/sq/Process <teefal> that's the question, karl <teefal> let's say we manage to do this <teefal> new visuals for home, paint, object catalog, load & save boxes --> ohshima (~ohshima(a)adsl-76-214-9-179.dsl.lsan03.sbcglobal.net) has joined #etoys <teefal> same functionality <teefal> doesn't feel like a major release <teefal> but from a documentation standpoint it is <teefal> at least a screenshot standpoint <teefal> load/save will be different a bit in functionality <bertf> provided anybody is going to work on your wish list <karlram> it would be nice if the paint visuals would be easier to add functionality to <teefal> yeah, i'd like several extensible options <teefal> some kind of gallery like thing ... object catalog like thing ... that's extensible for updates outside the release <karlram> bertf: that is the question <teefal> could be part of auto-updating <bertf> I'm still undecided if a major release number is warranted. but it does not hurt to decide later when we know better what is going to be in the release <teefal> okay, we could call it etoys 2010 for now :) <karlram> teefal: then we have plenty of time <bertf> teefal: as long as you don't go through the tracker and trash all priorities I'm fine with whatever you call it for now <teefal> i see this release as smoothing things out for the users <teefal> making it easier, more appealing, easier to update, etc <teefal> finessing <teefal> easy to get to the point where you like it <teefal> get them well past "now what?" <karlram> the new quickguides are a must <bertf> karlram: that goes without saying <teefal> a mechanism for auto-updating those as well as translations? <bertf> though I did list translations as #1 priority last week :) <bertf> teefal: I don't see auto-updating as a necessity <teefal> hey bert, is there any kind of jabber stuff in etoys now? <teefal> or squeak? <bertf> there isa package for jabber IIRC. bnot in Etoys <teefal> auto-updating for translations is a big deal from my end <teefal> if possible <teefal> getting the translations going on 200 to 2000 laptops in haiti :) <teefal> with new ideas coming in regularly <teefal> "Would you like to download the latest translations?" <teefal> etc <bertf> you could put translations in the XO bundle <bertf> and SUgar has a mechanism for updating those <bertf> but implementing a general update mechanism that works on all platforms? very hard. <teefal> well, bert, what do you think? independent of who does work? <bertf> think about what? <teefal> ah, sorry, was answering to a line above <teefal> got lost in the scroll <ohshima> For easier use and more appealing etc., fixing the showcase server would be good, too. <teefal> what specific fixes, yoshiki? <teefal> okay, well, send an email, gotta continue my talk with adam <ohshima> JIRA would show them, right? It takes 15 seconds just to look at a page, comments misfires all the time, project linking changes wrong project's name, no non-latin1 support, etc., etc. <teefal> pages should be loading faster <teefal> non-latin1 is known <teefal> misfires and linking still a problem? <teefal> need more examples rather than say "all the time" <teefal> examples <teefal> doing my best ... bye all <karlram> could we distribute bye <matmo> bye <karlram> sorry, bye :-) <bertf> matmo: would you need any input form our side? <bertf> from <bertf> it would be cool to give the GStreamer stuff a second look, foe video playback <matmo> not yet thanks, just make me aware of any issues not logged. Found one problem in etoys video today <bertf> well there are many guess :) <bertf> I had it on my todolist to make xv overlay work for video playback, that would be awesome <matmo> gst would be nice but first v4l since it's use across the three (one stone, three birds :-) ) <ohshima> It does take 10-15 seconds still so giving examples is hard^^; On http://squeakland.org/showcase/project.jsp?id=9781, Richo's comment was supposed to go to my project, Also on http://squeakland.org/showcase/project.jsp?id=9781 my comment was supposed to go to my projects. The name of http://squeakland.org/showcase/project.jsp?id=9783 was changed. <bertf> matmo: I thought Scratch used its own Camera plugin, the theV4L plugin? <teefal> okay, will look into it <matmo> I will check out xv but overlay prevents doing interesting things like sampling colour at certain points (eg, simple movement detector) <bertf> matmo: that's the trick - cheat but don't get caught ;) <matmo> yep, Scratch camera plugin use v4l internally. Scratch video protocol is simple but I have prodded John today about replacing it with the v4l plugin <bertf> oh, why? <matmo> why what? <bertf> I rather thought Etoys might switch to the Camera plugin <bertf> so we get camera on the other platforms too <matmo> v4l give much more control over say brightness, contrast, etc <bertf> but in Scracth you already have image filters ... <matmo> doesn't help if the picture is crap to start off with ;-) <bertf> IIRC the brightness controls in the v4l plugin are just post-processing the image too <matmo> and time consuming <bertf> and the XO camera does auto-gain which I think can't be disabled <matmo> possibly but camera capabilities vary, eg, on the N900 it can do focusing even though fixed lens <bertf> yes. I just think that's not exposed in the plugin <bertf> anyway, great that you are looking into that :) <bertf> strictly on Linux though, right? <bertf> AV on other platforms could use some overhaul too ... <matmo> is there a general preference for simpler video interface like Scratch? <matmo> Linux, yep, only <matmo> (me now almost completely weaned off windows) <bertf> I wouldn't say preference, but so far the camera is underused in Etoys so a simpler vesion would be okay IMHO <matmo> ok, I'll takie it into account (but then none of the compexity should surface to end user, only optios) <bertf> but I have a strong preference for it working identically across platforms <matmo> (options) <bertf> right <matmo> Is this a good time to mention WA idea? <bertf> if you feel so :) <bertf> Randy was busy preparing math lessons for haiti <bertf> guess that's why he did not respond yet <matmo> Quick version: anyone interested in pulling WolframAlpha results directly into etoys? <matmo> re Randy, not yet but that explains why, thanks <bertf> I don't think WolframAlpha is really well known yet, so you might have to explain more. but it would be awesome :) <bertf> Though I have no idea yet how this could look like in Etoys. <matmo> http://www.wolframalpha.com/screencast/introducingwolframalpha.html ... <bertf> but for the table data stuff Richo is working on this would be an excellent data source <matmo> it's the inferences that a search returns that is most interesting, to me at least. Could be good to inspire children to expand their investigations into the real world <bertf> well, they could use a browser for that <matmo> probably the difficult part is what to do with unexpected results but certainly Richo work would be good for presentation <matmo> browser yes, much better integrated don't you think? <matmo> otherwise cut&paste (then what?) distracting <matmo> anyway, I don't want to hijack the discussion so I'll leave the idea sitting their until feedback <matmo> (there) <karlram> i did some simple stuf for motion tracing :http://wiki.laptop.org/images/5/54/JournalMorph.005.pr <karlram> wrong, here http://wiki.laptop.org/images/6/6c/CamTrack-1.xo <matmo> karlram: thanks, I'll take a look <bertf> hehe. yeah, we'd need an educator or a scientist really to come up with ideas to use those data properly in Etoys <karlram> ricos stuff is nice <bertf> okay, one hour is up, anything more for today? <karlram> anybody have loots of money to give me ? :-) <karlram> he he <matmo> only a couple of coppers. sorry ;-) <bertf> karlram: what for? <karlram> just to be able to work on etoys instead of my day job :-) <bertf> karlram: now wouldn't that be cool :) <karlram> we can all dream <karlram> :-) <bertf> Thanks everyone! Next week, same place, same time :) <matmo> ok, bye all <karlram> bye all
