Welcome to Irreal

This is a blog primarily about Scheme and Lisp and their world of

infinite fun. As part of exploring that world, I'll also consider

related subjects such as Emacs, Slime, Org-Mode and, really, anything

else that excites my geek sensibilities.

The idea for Irreal came about when I stumbled upon a series of

posts on Eli Benersky's Website in which he presented his solutions to

the problems in Structure and Interpretation of Computer Programs

(SICP). I have long considered SICP to be one of the best books on

the art and craft of computer programming ever written. Because it

had been some time since I'd read SICP and I'd never worked through

all the problems, I decided that I would reread the book and write up

solutions to the problems in a form suitable for a solution manual—I

was aiming at the level of detail in the solutions to the exercises in

Knuth's Art of Computer Programming. One of the main purposes of

this blog, at least initially, is to record observations about the

exercises, their solutions, and any other technical issue that comes

up along the way.
