I worked with Sally on many projects. She taught me more that anyone else about what it is to do good science in the field of networking. The lengths she went to to convince herself that she really understood what was happening, and wasn't just being deluded by a simulation bug, or a lucky case. In particular, her shepherding of the ns2 simulator over many years, and the time she spent on the test suite, so it was possible to use ns to exchange ideas between researchers in a rigorous manner. She didn't care much what other people thought - she was by far a more careful critic of her own work than any reviewer of her papers. RIP Sally.
