Fuzzing is a technique to find bugs in your library by using it in ways that you have not imagined. Originally, fuzzing was limited to throwing random input at your library's entry points, and looking for crashes, but today's fuzzers are much more sophisticated.
After a brief description of what fuzzing is and is not, I will talk about various fuzzing options and tools, and then finish with results of fuzzing both libc++ and Boost.Algorithm.
