Re: [racket-users] Racket for Kids in 2017
Some really good thoughts there. I think key is to have some initial structured content to give him a springboard and then allow him to build out from there. LOL, yes, I agree wrt keeping web programmer (specifically JS) influences away to avoid brain rot! :D Even though my older son started with JS, he was able to have some serious balance to his understanding with my CS background which ultimately helped him to really go down the proper paths and to see things as they really are. Worlds of help (and yeah, the 80's methodology of hack it until you crack it really helps). One reason I throw Unix systems at them initially so that they can start learning that the shell is a useful thing... :) On Sunday, May 28, 2017 at 2:06:55 AM UTC-4, Neil Van Dyke wrote: > Have you looked at HtDP?

Re: [racket-users] Racket for Kids in 2017
Matthias, thanks for that. So essentially the scripted components are available in different focuses (e.g., HoC, Algebra, Reactive, Data Science, & Physics) here: http://www.wescheme.org/openEditor Correct? Are these to be used in a stepwise fashion moving from HoC to Algebra to Reactive, etc? It seems that after these are completed, you then recommend the "After Bootstrap" links.

[racket-users] DrRacket et al not starting in Sierra (10.12)?
I'm able to start DrRacket up just fine in 10.12 via the shell (e.g., `/Applications/Racket\ v6.6/DrRacket.app/Contents/MacOS/`), but double clicking the app just won't start. Anyone else see this or know of a work around for this issue? Same is true for all of the other apps in the `Racket v6.6` folder... -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
