==Sugar Digest==

“What we need are notions, not notations.” —Gauss

1. I gather that I am the only one who had never read the
"Mathematician's Lament", but in case you haven't read it in a while
and need a refresher on "notions" instead of "notations", see

It is also always worth rereading Marvin Minksy's essays on learning
math: [http://wiki.laptop.org/go/Minsky_essays]

2. One of the pleasures of working in the Sugar community is that you
get thoughtful feedback on your work from a wide range of people. Last
week I got a request from a teacher in Uruguay for some new features
in Turtle Blocks. (I included one—coordinate grid marked in
centimeters—in Version 109. I also got feedback from Alan Kay and
Barry Newell about the merits of the inclusion of an Arc block, which
motivated me to finally write a Sugar Activity based on Barry's book,
''Turtle Confusion: Logo Puzzles and Riddles''. Check out
[http://activities.sugarlabs.org/en-US/sugar/addon/4450]. Also, at
this weekend's Design Team meeting, I got very helpful feedback from
Sascha Silbe, Gary Martin, and Manuel Quiñones regarding the
enhancements I have been proposing to View Source (See
Perhaps the most significant change is that I now put a copy of the
cloned activity bundle into the Journal, thus maintaining equal status
for the clone within the Sugar infrastructure. You can find the
current patches here
and here [http://lists.sugarlabs.org/archive/sugar-devel/2011-June/031702.html].

3. There will be a Turtle Art Day in Costa Rica in July. We may hold
simultaneous workshops at other deployments as well: stay tuned (See

4. The TedxKids at Brussels talks are online at

5. Peter Robinson is very close to releasing Sugar on a Stick Version

6. I cooked up a patch to the Edit Activity—Sugar's plain-text
editor—to enable editing files from outside of the Journal. I am
waiting for Nate Theis, Edit maintainer, to accept the patches, but if
you want to play with it, see my clone on Gitorious

7. Martin Abente has implemented multiple-object select for the Sugar
Journal. His patches are not quite ready for release—there is a
performance-related issue with unnecessary list regeneration that
Martin is working on, but having tried it, even in its current form,
it is really nice.

Gary Martin has generated a SOM from the past few weeks of discussion
