[IAEP] Sugar Digest 2013-05-08

== Sugar Digest ==

1. Sugar Labs has been given 8 slots for student interns for Google Summer
of Code [1]. This means we'll be able to cover a lot ground this summer: we
have some very strong proposals and a great mentoring team. The next step
is for the mentors and the sugar-devel team to narrow the applicants down
to a short list. Many thanks to everyone who has lent a hand so far and to
Google for giving us this opportunity.

2. The sugar-devel team has been really busy pushing new features for the
next release and doing a general clean up of the code base. It is
remarkable the current pace of activity, especially around the efforts to
make HTML5/Javascript a first-class approach to Sugar activity development.
You can follow the work on the devel list [2] or by reviewing (and
submitting) patches on github [3].

3. I've been trying to contribute to the overall Sugar effort, but I tend
to get distracted by Turtle Blocks (AKA Turtle Art). When I was visiting
RIT a few weeks back, I was inspired to enhance the debugging features
Turtle Blocks. I came up with a simple way to introduce the concept of
break-points to the code. I had already introduced blocks to "hide" and
"show" the program as it executes. And through the "rabbit" and "snail"
buttons, the user can control the speed of program execution. What I did
was to combine these two concepts. By introducing a "hide" block into your
code, the code executes at full speed. Introducing a "show" block causes
the program to run slowly and display the status of all of its "variables"
as it runs. A subtle change, but what it allows one to do is to surround
code you want to debug with a "show" and "hide" blocks. Small blocks of
code can be examined while the larger program runs at full speed. Really
helpful for debugging complex projects.

4. I am also working on another new feature, this one at the request of the
teachers who have been using Butia in Uruguay. The idea is to be able to
save a stack of blocks for reuse in multiple projects (instances). The way
to do that currently is to open a project, copy the stack to the clipboard,
and then paste it into a new project -- too clumsy to be used on a regular
basis. The new feature allows users to save a stack to a custom palette.
This palette is loaded with each instance of Turtle, so it means the stacks
are available as if they were extensions of Turtle itself. It makes it even
easier for end-user customization.

=== In the community ===

5. We'll be celebrating International Turtle Art Day (Día Mundial de
TortugArte) in October. Our objectives are to:
* Promote the use of Turtle Art
* Share and promote best practices
* Celebrate projects for children and teachers
Details on how you can participate will be made available soon.

6. How embarrassing [4].

=== Tech Talk ===

7. Laura Vargas reports that Hexoquinasa v0.9 (BETA2) has been released [5]
and is in the hands of the Ministry of Education of Perú, where it will
undergo testing.

8. Daniel Narveaz reports that "the initial bits of the HTML activities
work has landed. It should now be relatively easy to start writing an
activity."

(1) You'll need the latest Sugar development environment [6].
(2) Then open a shell and move to the source directory:
 make shell
 cd source
(3) Create an activity based on a template
 volo create my-activity ./sugar-html-template
(4) Install the activity for development as usual
 cd my-activity
 python setup.py dev
(5) To interact with the platform you will need to add the sugar-core-html
library to your activity
 volo add -f ./sugar-html-core
