I regularly use errno, ts, and sponge; I've found them quite useful. errno helps when you find yourself with a raw error number in a debugger, log, trace, or memory dump, or if you just want to figure out the most sensible errno code for your API to return. "ts %.s" helps when debugging how long a program takes. sponge solves the "read this file, process it, write the same file back out" problem.
