I retired from Perimeter College of Georgia State University on January 1, 2017. I am no longer teaching computer science, nor do I expect to return to teaching in that field. I am leaving this website up for the time being since others have found it useful; however, I am no longer maintaining it or creating new content. I have removed much of the content that is specific to the courses at Perimeter College already. Expect that as time goes on, links will break and not be fixed, and content will become out of date. Eventually I will remove this website when I think it is out of date enough to no longer be useful.
Thank you for being my audience for the past twenty-plus years.
