Changes

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 [http://www.maa.org/devlin/LockhartsLament.pdf].

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 [[Design_Team/Proposals/Toolbars/View-Source_Enhancements]]). 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 [http://lists.sugarlabs.org/archive/sugar-devel/2011-June/031838.html] and here [http://lists.sugarlabs.org/archive/sugar-devel/2011-June/031702.html].
