I'm documenting the process of moving Turtle Art to git.sugarlabs.org. Marco has posted instructions [[Development Team/Git#Import_a_module_from_dev.laptop.org|here]], but of course I didn't have them at hand when I started. So far:
 
 
:1. I created an account on git.sugarlabs.org by selecting the register link on the home page.
 
:2. I created a new project by selecting the new link on the project page.
 
::There were lots of questions I didn't know the answer to, such as what tags I should be using, but you can answer most of them after the fact... I did screw up (at least) one thing: I hadn't noted that the project name needs to be all lowercase... but it was easy to change.
 
:3. I am not sure how to push my project.
 
::Morgs pointed out that if you go to http://git.sugarlabs.org/projects/turtleart/repos/mainline it tells you a "push" URL.
 
git remote add origin gitorious@git.sugarlabs.org:turtleart/mainline.git
 
# to push the master branch to the origin remote we added above:
 
git push origin master
 
# after that you can just do:
 
git push
 
:4. I finally looked at Marco's [[Development Team/Git#Import_a_module_from_dev.laptop.org|instructions]] and so I added the pootle user as a committer.
 
:5. Where should I put the .xo bundle? And the source tarball?
 
::there is [http://git.sugarlabs.org/projects/sugar-tools/repos/mainline/blobs/master/release a script] for generating and posting changes that covers all of these details.
 
 
I had a bit of trouble pushing a new change to gitorious today. I had to use the --force flag for some reason. We suspect it may have something to do with the fact that one of the files I pushed is a binary file. Will report back what I find. (Seems to work fine when there are no binary files to add/push.)
 
git push -fv
 
 
I have been trying to use release.py with no luck so far either. (It has a dependency on the feedparser python library, which is easy enough to install.) It complained about a mismatched tag, so I used the --version flag to force the same version number as in my activity.info file. Then I got this error:
 
 
nothing added to commit but untracked files present (use "git add" to track)
 
Traceback (most recent call last):
 
  File "../release.py", line 325, in <module>
 
    main()
 
  File "../release.py", line 314, in main
 
    release.tag()
 
  File "../release.py", line 170, in tag
 
    subprocess.check_call(['git', 'commit', '-a', '-m' , '%s' % message])
 
  File "/usr/lib/python2.5/subprocess.py", line 462, in check_call
 
    raise CalledProcessError(retcode, cmd)
 
subprocess.CalledProcessError: Command '['git', 'commit', '-a', '-m', 'Release 26']' returned non-zero exit status 1
 
 
Is this because I did the git commit and git push by hand before running release.py?
 
 
----
 
 
Use
 
git-pull
 
to periodically pull pootle updates to the project .po files (every Friday?)
 
 
Also, run
 
python setup.py fix_manifest
 
to update the .mo files after updating the .po files
 
 
----
 
 
alsroot taught me about another git feature: tags
 
 
git tag -m "Release 36" v36 HEAD
 
git push --tags
 
 
----
 
 
bertf explained to me that git-pull does a combination of fetch and merge, so to merge a patch...
 
 
git pull git://git.sugarlabs.org/infoslicer/alsroots-clone.git master
 
 
 
A few notes re moving to the Sugar Labs infrastructure:
 
 
* use git init to create a new project
 
 
* source packages now go in
 
<strike> shell.sugarlabs.org:/upload/sources/sucrose/fructose/</strike>
 
download.sugarlabs.org:/var/www-sugarlabs/download/sources/sucrose/fructose/
 
 
* don't forget to update addons as well!!
 
 
* and to copy the tar file to download.sugarlabs.org
 
download.sugarlabs.org:/download/sources/honey/...

Regarding the Sugar Labs Oversight Board

While it has been my goal to help get Sugar Labs to a point of self-sustainability, I don't think we are yet at that point. My goals for 2010 are to focus on fund-raising and further refining the organizational and governance models.

A bit about me and my role in Sugar Labs: I was part of the Sugar team at One Laptop per Child that left to found Sugar Labs in March of 2008. I have worn a few different hats within the organization: activity developer, occasional contributor to Sugar core, member of the deployment team, the marketing team, and the activity team. I was a lead author of the FLOSS Manual on Sugar. I am presently the executive director of Sugar Labs. I also represent Sugar on the GNOME technical advisory board and the Squeakland board. I have been a GSOC mentor and am participating in several pilot deployment projects of Sugar on a Stick.

To do

  • get Frame test set up in Peru/Uruguay/Paraguay</srike>
  • <strike>New Activity templates
Much of the information that is consistent across activities can be held in activities.s.o. (dfarning 22:28, 16 June 2008 (UTC))
  • Follow-up with Linux Foundation
  • Draft membership agreement for Sugar Labs
  • rebase Turtle Art on SVG
  • ask SFC for pointers to lawyers in SA
  • start writing NSF/USAID proposal
  • local-labs proposals
  • NSF Creativity grant
  • Babson brief
  • Watertown follow-up
  • Curriculum guides from GPA programs

Done

Recent writing about Sugar and learning

(I also blog the weekly Sugar Digest.)

The slides from a talk I gave about Sugar at the Women2Woman conference are here and here.

Portfolio

I am making a "TurtleArt: inspired portfolio tool. See TAPortfolio for more details.

Turtle Art variables

Following the lead of Luis Michelena, I've added named blocks and stacks. I plan to add push and pop next, which should greatly expand the range of possible constructions.

Turtle Art push and pop

While it is not the intent that Turtle Art be a full implementation of Logo, but there has been some discussion on teh Sur list about adding some capability for passing arguments to stacks. (and to support recursion). I have added a FILO and push and pop blocks to enable this functionality. I am looking for feedback. regarding this choice.
