Small suggestion: add navigation arrows at the bottom of the page as well.

Re: Interactive SICP
#22When I worked my way through SICP I found the following javascript based scheme REPL very useful:

Unfortunately, searching for jsscheme in Google gives you a list of many different projects that either share the same name or have a very similar name.

#23I created an implementation of R5RS in Javascript[1] that perhaps you'd be interested in. I know you already have one, but you might have opinions and needs that could influence my implementation. I got stalled trying to get (real) macros to work, but I already had a Scheme->JS FFI and asynchronous evaluation without the use of web workers.

#24This is very cool, every innovation helps. I wonder if it wouldn't be helpful for learning to add execution visualization, such as provided at http://www.pythontutor.com/visualize.html (click "Visualize Execution")
Re: Interactive SICP
#25Thanks a bunch! SICP is my current course literature at Linköping University.
Consider yourself lucky! We had some boring and entirely too basic OOP-y course (with Java, of course). I'm reading SICP now (this beautiful PDF version: https://github.com/sarabander/sicp-pdf/blob/master/sicp.pdf ). I would've loved to have had it when I was in college.

#26Hello everyone, author here. Sorry for forgetting to enable billing on appengine - the page should be displaying now. I shared Interactive SICP with HN last year ( https://news.ycombinator.com/item?id=4860370 ), and thought it was time to share it again. Since that time, I've - added more sections of the book - replaced the javascript scheme engine - added mathjax - made the evaluation asynchronous (to avoid freezing…
i would definitely keep running with this. would def support. iconic text, and this makes it easy to dive in and play with. perhaps the examples appear in a mini-IDE on the right, where you click the example, it shows up in the IDE. click compile button, and it will execute the sample.

How do you get asynchronous evaluation without the use of web workers? My understanding is that, without web workers, javascript and the browser share a single thread, and executing javascript freezes the UI.

#28It's not obvious how to run examples after editing — it's explained in readme.md, but I didn't see it the book itself.
[It's Ctrl-Enter. Actuallghy just pressing Ctrl is enough.]
Ideas to make it more discoverable: - re-run an expresion when the editor is unfocused. - add a "▶" button in the corner of each editor. - add a tooltip with the kbd shortcut on the "▶" button
Re: Interactive SICP
#29Very cool! I have also been making an (iPad) app to help people get through SICP and I somehow didn't run into this.
If anyone is interested in reading SICP now, you should try out my app. We find you someone and you have a good conversation about the material each week through video chat and a whiteboard. We aren't launched yet, but you can check out our simple demo (https://www.youtube.com/watch?v=DlUTKzrqECE) and send me an email if you want to try the beta. bridger@understudyapp.com

Very very cool. One thing that I would like would be if 'tab' jumped to the next example/input area?
