But personal computers are still prone to bugs, conflicts, viruses, spyware infestations, hacker and phishing attacks, and--most of all--user error. Unfortunately, technical support from computer…

The late 1980s was an exciting time to be a CIO in higher education. Computing was being decentralized as microcomputers replaced mainframes, networking was emerging, and the National Science Foundation Network (NSFNET) was introducing the concept of an "internet" to hundreds of thousands of new users. Security wasn't much of an issue;…

Information technology (IT) departments are ruled by a kind of Maslow's Hierarchy of Needs: The big-tech stuff--the operating systems, the networks, the data centers--gets the priority, food-and-shelter attention, while upgrading the backup power supplies, evaluating new projector mounts, and taming that rat's nest of classroom cords fall…
