Ada Lovelace: Enchantress of abstraction

This is a nice short video about her. And I read a bit more about her in this book: http://www.amazon.com/The-Information-History-Theory-Flood/d...

If you're in the UK, I recommend making the effort to visit the display at the Bodleian.
And not lacking in self-confidence, either.
[Edited for clarity]
For example, at the high water mark of political correctness in the early 1990s, Harvard distributed to its faculty and staff a brochure saying, among other things, that it was inappropriate to compliment a colleague or student's clothes. No more "nice shirt." I think this principle is rare among the world's cultures, past or present. There are probably more where it's considered especially polite to compliment someone's clothing than where it's considered improper. So odds are this is, in a mild form, an example of one of the taboos a visitor from the future would have to be careful to avoid if he happened to set his time machine for Cambridge, Massachusetts, 1992.
