Is Computer Science Science?

A must read article from the latest Communications of the ACM (v4i8) is this one by Peter J. Denning. He makes the case that, yes, CS is a science and it investigates natural and man-made information processes. This issue also has an extensive feature section on IT in China. Oh yeah, and an "interesting" little piece Self-plagiarism in computer science by Christian Collberg and Stephen Kobourov. It tackles the issue of scholars "reusing" their ideas and basically publishing the same result over and over with slight modification.
