The book--which has been mentioned favorably on HN before--can be thought of, basically, as: "Perl meets SICP".

Which provides tangible support for my notion that Perl can be viewed as a kind of blue-collar Lisp :-)

Mandatory mention that the classic SICP ("Structure and Interpretation of Computer Programs") aka The Wizard Book, by Sussman and Abelson, is also available free online from MIT Press, here: http://mitpress.mit.edu/sicp/

Lecture-videos, from courses using the book at MIT and from Berkeley, can also be found online.

There's also at least one blog of someone going through the book and sites where the problems have been implemented in languages other than Scheme.

I take it you mean http://eli.thegreenplace.net/category/programming/lisp/sicp/ ?

If so yeah great resource.

Possibly, though I'm not sure, given that there are a number of bloggers who blogged their journey through SICP -- Googling the two terms, SICP and blog, gets me these blogs, among others:

http://www.kendyck.com/archives/2005/04/24/index-of-solution...

And those are just a few from the first page of Google results...

Then there's a guy who started doing the SICP problems in Arc:

And, here's a page of translations of the problem-solutions into a whole bunch of other computer languages:
