I caught the end of a Radio 4 programme yesterday evening that appeared to be about Ada Lovelace - did anyone else hear it? I'm annoyed that I missed it, but then I suppose that if I never bother to find out what's going to be on I've only got myself to blame. There's Listen Again, but unfortunately the places where I want to listen to the radio are not at all the same places as the ones with computers, so I'm a bit stuck on that.
