Etoys developer chat log
by Bert Freudenberg 08 Sep '10

08 Sep '10

Hi all, almost missed the chat yesterday. And when I logged in I got distracted by #olpc-devel talk. A minute later David came back, but I didn't see that. Sorry. But: If I'm not there, that's no reason not to chat :) Anybody can lead the discussion if it gets too disorganized, but usually we're pretty civilized, so it should rarely be necessary. So here is a rule: Do not wait more than 15 minutes. Just start. I'll see it in the logs later so I can still post a summary (though it would be awesome if someone beat me to it). Anyway, next chat is next Monday, same time as always: http://tinyurl.com/3ytdm3d Hope you'll be there (and I'll try to attend too). - Bert - [21:02:37] --> Richo2 (~c9d56472(a)skylab.immuexa.com) has joined #etoys [21:05:08] --> dcorking (~dcorking(a)82.152.173.174) has joined #etoys [21:05:13] <Richo2> hi [21:06:06] <dcorking> hi Richo2 - when does the meeting start? [21:07:36] <dcorking> is storybot down again? [21:11:53] <Richo2> I think it should have started already [21:13:09] <dcorking> I have only lurked in a couple of these. bertf normally leads them doesn't he? Is randall travelling at the moment? [21:13:31] --> scottwal (~scottwal(a)99-40-5-235.lightspeed.sntcca.sbcglobal.net) has joined #etoys [21:17:00] <-- Richo2 (~c9d56472(a)skylab.immuexa.com) has quit (Quit: CGI:IRC (Ping timeout)) [21:21:13] <bertf> hi folks - sorry I'm late [21:21:26] <bertf> you could've started already ;) [21:24:59] <bertf> dcorking: storybot has been down for months, and it's unlikely to come back [21:25:12] <bertf> jecel was looking onto other logging options [21:25:19] <bertf> for now I just email the logs manually [21:26:18] <dcorking> shame: I guess a decision should be made and the link removed from http://squeakland.org/discuss/ [21:36:37] <dcorking> is the meeting starting? if not, any thoughts on jecel's idea on porting Cog VM to the XO-1? [21:38:46] <jecel> I was looking at the Cog sources to get an idea of how complex this would be. It seems doable, but not easy [21:40:05] <dcorking> hmm. Sounds like something that would distract the squeak experts from doing the next Sugar release on time, and not something for average smalltalkers. [21:40:25] <jecel> About the logging, I didn't remember we had agreed that I would check the options and so haven't yet done so [21:40:47] <dcorking> however, I wonder if qemu could be used to emulate the missing instructions: at least as a proof of concept [22:07:44] <dcorking> is the meeting over? [22:10:43] <dcorking> does the showcase still give trouble when a user uploads a new version of an existing project? [23:47:14] <-- dcorking (~dcorking(a)82.152.173.174) has quit (Quit: Leaving)

S3 - Deadline Extension
by Yoshiki Ohshima 30 Jul '10

30 Jul '10

It looks like there is a good chance to get your paper in... -- Yoshiki --------------------------------------------------------------------- The deadline for submitting papers to S3 has been extended to August 13th. The program committee welcomes your submission! ====================================================================== *** Workshop on Self-sustaining Systems (S3) 2010 *** September 27-28, 2010 The University of Tokyo, Japan http://www.hpi.uni-potsdam.de/swa/s3/s3-10/ In cooperation with ACM SIGPLAN === Call for papers === The Workshop on Self-sustaining Systems (S3) is a forum for discussion of topics relating to computer systems and languages that are able to bootstrap, implement, modify, and maintain themselves. One property of these systems is that their implementation is based on small but powerful abstractions; examples include (amongst others) Squeak/Smalltalk, COLA, Klein/Self, PyPy/Python, Rubinius/Ruby, and Lisp. Such systems are the engines of their own replacement, giving researchers and developers great power to experiment with, and explore future directions from within, their own small language kernels. S3 will be take place September 27-28, 2010 at The University of Tokyo, Japan. It is an exciting opportunity for researchers and practitioners interested in self-sustaining systems to meet and share their knowledge, experience, and ideas for future research and development. --- Submissions and proceedings --- S3 invites submissions of high-quality papers reporting original research, or describing innovative contributions to, or experience with, self-sustaining systems, their implementation, and their application. Papers that depart significantly from established ideas and practices are particularly welcome. Submissions must not have been published previously and must not be under review for any another refereed event or publication. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Revised papers will be published as post-proceedings in the ACM Digital Library. Papers should be submitted electronically via EasyChair at http://www.easychair.org/conferences/?conf=s32010 in PDF format. Submissions must be written in English (the official language of the workshop) and must not exceed 10 pages. They should use the ACM SIGPLAN 10 point format, templates for which are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. --- Venue --- The University of Tokyo, Komaba Campus, Japan --- Important dates --- Submission of papers: *EXTENDED* August 13, 2010 Author notification: August 27, 2010 Early registration: September 3, 2010 Revised papers: September 10, 2010 S3 workshop: September 27-28, 2010 Final papers for ACM-DL post-proceedings: October 15, 2010 --- Invited talks --- Yukihiro Matsumoto: "From Lisp to Ruby to Rubinius" Takashi Ikegami: "Sustainable Autonomy and Designing Mind Time" --- Chairs --- Robert Hirschfeld (Hasso-Plattner-Institut Potsdam, Germany) hirschfeld(a)hpi.uni-potsdam.de Hidehiko Masuhara (The University of Tokyo, Japan) masuhara(a)graco.c.u-tokyo.ac.jp Kim Rose (Viewpoints Research Institute, USA) kim.rose(a)vpri.org --- Program committee --- Carl Friedrich Bolz, University of Duesseldorf, Germany Johan Brichau, Universite Catholique de Louvain, Belgium Shigeru Chiba, Tokyo Institute of Technology, Japan Brian Demsky, University of California, Irvine, USA Marcus Denker, INRIA Lille, France Richard P.

I know there were problems *booting* > SoaS-2 on Intel Macs. Maybe these have been solved now. I don't think so. Or it has been silently fixed and not advertised. But Mac support would be a major achievement so I think it would have been mentioned. The only way I was ever able to run Sugar on a Mac was using a PC emulator. Personally I still wouldn't boot my Mac into SoaS even if it worked.

For those who do not know Etoys-To-Go, it differs from SoaS in that you do not need to boot your machine from it. Instead, it packs virtual machines for Mac, Windows, and Linux, which all run the same system image and save to the same directory. You just double-click. Get it from http://squeakland.org/download/ and unzip onto a USB stick (or anywhere really). It would be cool if SoaS had VMs, too (e.g. Qemu or VirtualBox), maybe like http://www.erikveen.dds.nl/qemupuppy/ which allows booting and emulation using the same disk image. Though emulation-only would be simpler to set up. Is anyone still preparing emulator disk images like there were for OLPC builds? - Bert - >> May I expect something similar with the added advantage of being able >> to use all the programs distributed for the XO? > > I think that's the stated goal, but I don't know for sure how close to > it SoaS-3 got. > > Since SoaS-3 ships the same version of Sugar used in Dextrose, I would > expect compatibility with anything from activities.sugarlabs.org to be > very high.

Re: [squeakland] [realness] Sugar On A Stick for Macintosh
by Carlos Rabassa 24 Jul '10

24 Jul '10

Thanks, Bernie, Hope my request was clear. I would like to hear in plain English, suitable for retired old engineers like me, teachers, relatives and volunteers whether or not Sugar On A Stick is ready to be used by the general public without any special knowledge or precautions. If the answer is yes, I would like to know if it is OK to use Windows and if it is OK to use MacOS10. As I mentioned to you when we met in person, I used many times Etoys To Go. I am very impressed with how easy it is to use and how well it works. You may start an Etoys project in Windows or in Mac and switch many times in the middle of the project to different computers. Some may be using Windows and some MacOS. You may store the projects in the same pendrive. Everything is seamless and leaves no traces in the finished project about its origin, created in multiple machines with different operating systems. May I expect something similar with the added advantage of being able to use all the programs distributed for the XO?

showcase improvements
by Timothy Falconer 23 Jul '10

23 Jul '10

Hi everyone, Yesterday and today I put in about seven hours of Squeakland showcase and website work, mostly fixing bugs. The most noticeable change is that you can now make your projects public immediately without needing editorial review. We'll still have the review, but it can happen after the project is visible, usually in a day or less. Projects post to the site much faster, and some web upload bugs have been fixed. Here's a quick list of the issues I worked on: * http://tracker.squeakland.org/browse/SQ-616 (It takes way too long for projects to be made "Public") * http://tracker.squeakland.org/browse/SQ-734 (author accounts cannot access their own projects in showcase) * http://tracker.squeakland.org/browse/SQ-677 (projects in featured showcase do not open from website) * http://tracker.squeakland.org/browse/SQ-706 (Can't Upload new Version of Existing Project to Showcase via Web) * http://tracker.squeakland.org/browse/SQ-590 (Uploaded Project, Made Public, Had Comment, But not visible) Along with several other fixes that didn't have issues. Anyway, sorry to be so absent this year. Things have settled down, so you can expect more showcase improvements. Have a great time at Squeakfest everyone! Have fun with the Showcase!

European visitor learns first hand about Plan Ceibal in Uruguay
by Carlos Rabassa 22 Jul '10

22 Jul '10

We met Christoph Derndorfer in the recent OLPC Realness Summit in St. John, Virgin Islands. He mentioned his intention of visiting Uruguay soon and, of course, we offered to show him our country. But when he contacted us to let us know he had just arrived in Montevideo, we were out of town. So we asked Paolo Benini, a Volunteer with RAP Ceibal, the volunteer network to support Plan Ceibal, to play host for Christoph in our absence. >From the reports he filed, I can clearly see Paolo did such a great job that after all, it was probably a good thing for Christoph that we were not around. Thanks Paolo! Thanks to all the volunteers that helped Christoph! Thanks Christoph for the two interesting reports you published: OLPC in Uruguay - More than just Plan Ceibal http://www.olpcnews.com/countries/uruguay/olpc_in_uruguay_more_than_just_pl… and RAP Ceibal - Uruguay's volunteer network http://www.olpcnews.com/countries/uruguay/rap_ceibal_uruguays_volunteer_net… Carlos Rabassa Volunteer Plan Ceibal Support Network, RAP Ceibal

questions about book options
by Rita Freudenberg 21 Jul '10

21 Jul '10

Can someone tell me what "uncache page sorter" and "make a thread of projects in this book" really does? You can find these options if you enable advanced controls for a book, then click on the menu icon and choose "advanced". We need this information for the Etoys reference manual. Thanks, Rita
