Check out this link - web.mit.edu/PostScript/obfuscated-1993/labyrinth.ps - it is my submission to the obfuscated postscript contest web.mit.edu/PostScript/obfuscated-1993/WINNERS and it generates random mazes together with a solution, with all the computation done on the postscript printer. Edit the postscript as a textfile to change the options.

Yes. We have found that the largest models, trained for a long time on massive data sets, tend to have very rich interpretable structure. Developing interpretable methods for massively parameterized models such as GPT-X is the topic of ongoing work in my group, and we have found that large models are a very target-rich environment. Oddly enough, one of the more difficult problems is to clarify is how interpretable structure emerges in the very simplest toy settings, trained on small problems, where the emergent structure is less obvious.

Dr. Bau , what is the best way to reach you ?

Thank you!

Thank you Kate!!!

Matthew Fahrenbacher - there is a special script that you need to load to get the orange markers. Add the following to the beginning of your program: await loadscript '/lib/angles.cs', defer()

David Bau Thanks for getting back to me. I had already included that loadscript command in my program - it does cause the orange arc and lines to appear, but NOT the degree measurers. Here is my program: matfah.pencilcode.net/edit/ExteriorAngles

Ah hah, I understand now. That's a bug in angles.cs! I have fixed that library now.

David Bau Thanks! It works perfectly now.

Yeah, that program is a ton of fun. You can play with the orbit program here: guide.pencilcode.net/edit/motion/orbit

Thank you David. A couple of years ago, me my 6th grade daughter spent at least 2 days in excel spreadsheets and later python pygame scripting to calculate orbits first using sin.cos formulae and the using newtonian equation. She learned a lot. But none of those frameworks can come anywhere near what you have now. With your platform, we can probably do that in an hour, focusing right only on mechanics of orbits rather than the mechanics of the language. Awesome.

Please pardon me but i can not help shower more praise to you - at the elegance of your expression (code), not one unnecessary letter! what a masterly art. I have previously learnt from your blog (RPS, your js tutorials) and have a great appreciation for your verbal computational and visual imagination and generousity. Thanks for sharing the great work. I will introduce pencilcode to more kids.

Ravi Annaswamy Thanks for the kind words! Think about hosting a "CS Education Week" group December 9, e.g., masstlcef.org/hour-of-code/ . The idea is to denote a week to inspire kids to learn CS by providing a one-hour easy-to-teach CS lesson. Pencil Code "Hour" materials are being posted here: event.pencilcode.net/hoc2013

thank you, I will consider, that is a great idea

agree even though i am a kid

Interesting turtle bits

Note that the site is now called "Pencil Code" - I have just published a short book to go along with the site: pencilcode.net/wish
