===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.

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

Some procedures for setting up the palette and the shade functionality:
 +
 +
to tasetpalette :i :r :g :b :myshade
 +
make "s ((:myshade - 50) / 50)
 +
ifelse lessp :s 0 [

 +
make "r (:r * :s)
 +
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

====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.
