Buried within the External Links menu on the GDT homepage is a link to the Risks Digest moderated by Peter Neumann.
Neumann is a Principal Scientist in the Computer Science Lab at the Stanford Research Institute (SRI). He has a PhD from Harvard and was a computer researcher at AT&T Bell Labs during the 1960s. He participated extensively in the design, development, and management of the Multics operating system. He has been a visiting lecturer at Stanford and Berkeley. His computing history goes on and on and on. Neumann's home on the WWW is at http://www.csl.sri.com/neumann/neumann.html.
The Risks Digest contains postings that document various and sundry problems caused by computers. Many of these postings are hard and scary to believe. I suggest you find time to read the Risks Digest.
