this is the greatest stuff on the web; not the cmu open learning initiative per se, but just universities & colleges doing this stuff generally speaking -- berkley, stanford (amazing for this stuff), mit (sort of set the standard) and several other top-tier schools. now i've never formally taken a programming class in my life, but via many of these on-line courses and their accompanying resources, I am now a software developer! i do have two (very unrelated) college degrees, but these on-line courses have definitely changed my life. thanks for the post...i love seeing this kind of stuff!
