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.

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

I added a "view source" for Turtle Art that exports Logo.

Some procedures for setting up the palette and the shade functionality:

make "s ((:myshade - 50) / 50)

make "s (1 + (:s *0.8))

make "g (:g * :s) 
make "b (:b * :s)
] [
make "s (:s * 0.9)
make "r (:r + ((100-:r) * :s)) 
make "g (:g + ((100-:g) * :s)) 
make "b (:b + ((100-:b) * :s))
]
setpalette :i (list :r :g :b)
end

to rgb :myi :mycolors :myshade
make "myr first :mycolors
make "mycolors butfirst :mycolors
make "myg first :mycolors
make "mycolors butfirst :mycolors
make "myb first :mycolors
make "mycolors butfirst :mycolors
tasetpalette :myi :myr :myg :myb :myshade
output :mycolors
end

to processcolor :mycolors :myshade
if emptyp :mycolors [stop]
make "i :i + 1
processcolor (rgb :i :mycolors :myshade) :myshade
end

to tasetshade :shade
make "myshade modulo :shade 200
if greaterp :myshade 99 [make "myshade (199-:myshade)]
make "i 7
make "mycolors :colors 
processcolor :mycolors :myshade
end

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.
