Comment on Teaching programming languages: a novel approach

Comments

The comments in this thread are so gushing that I suspected we were being scammed by vanity accounts trying to flog this guys wares (books), but they're mostly from big karma/long time readers so I was wrong.

Okay, so other than being a hyper-intelligent pan-galactic sex god, what has this guy done for us lately? (read as: request for more info and less gushing. Let's just take the gushing as given)

I guess a few of us have been through a programming language concepts course, and felt that the matter is really interesting, but that it could be better connected to what's happening on the ground. This guy is vocalising that perspective.

Also, Racket is promising. I think this is the first time we've had a scheme platform that has this combination:

- Simple installation

- Solid package management arrangements.

- Multiplatform

- Nice IDE.

- Free software

- Easy access to unix api

Other lisps have had a couple of these features. But Racket is the first lisp I've seen that feels like a serious alternative to perl/ruby/python. It may lack a solid standard library - I haven't looked into this yet.

So he made some contributions to Scheme. Anything else?

There's more, but if you just stop there and understand PLT's contributions to Scheme, you'll be gushing too.

"trying to flog this guys wares (books)"

Actually, he gives away the book described in the paper: http://www.cs.brown.edu/~sk/Publications/Books/ProgLangs/
