Recently I was asked for a name for a new server. Now a server dedicated to mapping is quite fittingly called "Amelia" - after Amelia Earhart, the first female pilot to fly solo across the Atlantic Ocean.
My naming strategy are Women in Science & Technology, and I'm if you are looking for inspiration beyond her and Ada Lovelace then here's a list to start with.

Ada Lovelace

who already gives her name to the Ada Initiative

Grace Hopper

one of the first programmers of the Harvard Mark I computer, and developer of the first compiler for a computer programming language

Florence Nightingale

for her great work as Mathematician and statistician, before she became sanitary reformer

Ursula Le Guin

Science fiction author. Her book The Dispossessed would be a good reference to opensource projects.

Barbara McClintock

Geneticists, received a Nobel prize for her discovery of jumping genes. No better way of reminding yourself and others to really look at the evidence, at each bug, instead of assuming that you know how it works

Rosalind Franklin

Critical contribution to the discovery of the molecular structure of DNA, RNA and viruses. And a reminder to give credit to others

Valentina Tereshkova

Soviet cosmonaut and first woman in space in 1963

Grete Hermann

Mathematician who did early work on quantum mechanics, born into a time when girls in Germany could only receive a higher school education in exceptions.

Mary Leakey

Marie Curie

no intro needed)

Tatjana Joëlle van Vark

Mechanical engineer, whose hand crafted machines and artefacts are among the best and most beautiful in the world)

Lise Meitner
