People, people, people, open source is great. I run Linux on my home computer, surf the Web with Mozilla Firefox, IRC with X-chat and program with gcc.
But this open source veneration needs to be taken down a notch. It's pretty nice in a lot of areas, but we need to stop bitching out anybody who chooses not to open source or released under the GPL their materials.
Carnegie Mellon must obviously have spent hundreds of thousands of dollars over the years to produce these materials and it's pretty hard to see what's in it for them and maybe even us if they make this "courseware" publicly available. Just think about this.
