xturtle online via processing.js !?

Hi, I am struggling around with interactive online py tutorials with https://launchpad.net/projects/intro-to-code (ith might become securely sandboxed soon, as pypy made it possible http://blog.sandbox.lt/en/WSGI%20and%20PyPy%20sandbox :) but one more thing is I'd like to let access xturtle functionality online - one possible way could be triggering tkinter to save its canvas to ps, and then convert them with imagemagic and show via web (animated gif or static) - but if pyjamas can render GUI for js (http://www.google.lt/search?&q=pyjamas+python ), mayby there is a way to **translate turtle commands to processing.js analogues** http://ejohn.org/blog/processingjs/ would it be difficult -- how do you think? -- Jurgis Pralgauskis tel: 8-616 77613; jabber: jurgis(a)akl.lt; skype: dz0rdzas; Don't worry, be happy and make things better ;) http://sagemath.visiems.lt

OO and story problems
by kirby urner 29 Mar '12

29 Mar '12

I've been haunting the math-teach list, as usual, suggesting we take a page from AP computer science and build our math around an interlinked, themed, consistent set of story problems -- rather than making these "meaningless" (deliberately). The opponents in this debate bring up the specter of political manipulation, propaganda, tainted "pure math" with someone's good ideas about applications. My approach to math teaching, as readers here know (some of 'em), is to bake OO into the matrix pretty early, meaning the idea of "math objects" (vectors, polyhedrons, rational numbers) connects to our Pythonic notion of types. Here's some background reading for any wanting to sample the more detailed nuances of this thread (on-going, and for over a decade for sure). http://mathforum.org/kb/thread.jspa?threadID=2289577&tstart=0 (most posters long time veterans of this list, with carved out positions) I also take it a step further in that the story problems under consideration often have a strong "off your duff" component, in that your mathematical reasoning translates into physical expenditure of energy. Yes, sounds a lot like summer camp (the "self quantification movement" also syncs up). http://fastwonderblog.com/2011/07/30/crunching-the-numbers-open-source-comm… http://hashtags.foxepractice.com/healthcare-hashtag-analytics.php?hashtag=Q… http://www.4dsolutions.net/presentations/urnermindstorm.pdf Kirby

Net Logo / Tractor Art

I'm downloading Net Logo in the background. Logo is making a come back in this new form, thanks to "complexity studies". http://www.flickr.com/photos/17157315@N00/5583591181/in/set-721576256460717… Turtles have become "agents" and the typical thing is to have thousands of them. http://ccl.northwestern.edu/netlogo/4.1.3/ Capturing the ideas in these new "chaos" related curricula was one of my objectives in building a super primitive ASCII graphic system built on Tractors versus Turtles. The Tractor-as-agent motif links me, conveniently to the Make: / DIY / open source / hacker vision of the Open Source Tractor: http://opensource.com/life/11/4/open-source-tractors-and-diy-manufacturing http://theshortearedowl.wordpress.com/2011/03/01/an-open-source-tractor/ And also: the 50 machines needed for your semi-autonomous campus / village / community. http://opensourceecology.org/wiki/GVCS_tools I hope to have some of my Tractor talks ready for lightning sharing at Pycon this March. Early draft of my code: http://www.4dsolutions.net/ocn/python/OST/ Kirby
