A few months ago I sent out a query for parsers for English. Now I have a slightly different query. Some time ago there was some discussion about the Unix user-interface. Here is an example of what can happen, even if you are reasonable proficient with Unix. I also wasn't paying attention as well as I should have been.
Children Being a parent is a soul-shattering experience which changes anyone who tries it.
I always read comments by people without children about child-raising with amusement. It is like a non-programmer talking trying to talk to a hacker about computers. Children are our investment in the future. If everything else was lost, but we still had children, there would be some hope. But with all the luxuries in the world, life would be pointless with no children to continue the mysterious journey of intelligence through the universe.
