What Every Computer Scientist Should Know About Floating-Point Arithmetic

Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will be called upon to compile floating-point algorithms from time to time; and virtually every op...

Safecracking for the computer scientist∗

This paper is a general survey of safe and vault security from a computer science perspective, with emphasis on the metrics used to evaluate these systems and the weaknesses that cause them to fail. We examine security against forced, covert and surreptitious safe opening, focusing on the mechanical combination locks most commonly used on commercial safes in the US. Our analysis contrasts the p...
