The RISKS Digest is now 20 years old. And this forum for discussion on risks to the public in computers and related systems in as invaluable as ever. It is an excellent source to read about the risks of modern computing equipment.
Over the 20 years, RISKS has covered a wide variety of topics, from computer problems in the Shuttle to a runaway car from hell to a thousands of flight getting canceled because of an overflow of a single integer.
Thanks for RISKS goes to Dr. Peter G. Neumann, who has been editing RISKS from day one and has published several books on the topic.
Nowadays RISKS is also of course available as an feed from ncl.ac.uk.
