There's insane amounts of great stuff hidden in the various nooks and crannies of the NIST website. Some of my other favorites: Engineering Statistics Handbook http://www.itl.nist.gov/div898/handbook/index.htm Digital Library of Mathematical Functions http://dlmf.nist.gov/ The Quantum Algorithm Zoo http://math.nist.gov/quantum/zoo/

Just to mention one that's usually quite ignored, I love the simplicity and usefulness of the Levenshtein distance: https://xlinux.nist.gov/dads/HTML/Levenshtein.html I once implemented it in typical scenario where sales people had to look for a client, but it could be written as: 1/ That Client With A Strange Name, Ltd. 2/ The Client With Strange Name, Ltd. 3/ That Client With A Strange Name 4/ [etc] It worked really well and avoided lots of duplicated entries.
