Practice is a project mainly written in Common Lisp, it's free.
Common Lisp practice.
I'm trying to learn Common Lisp. I'm playing with Emacs, SLIME and SBCL.
This directory contains a list of CL-noob solutions to some of the easier problems in Ed Karrels collection.
http://www.karrels.org/Ed/ACM/
To build & load:
(require :asdf) (asdf:operate 'asdf:load-op 'practice)
Most of the lisp files contain solution to a problem. Instructions on playing with the code are at the start of each file.
There are also some files containing common utils.
The code is hereby declared public domain.
UPDATE: some problems from http://streamtech.nl/site/problem+set
