Can someone clarify: wasn't it Oracle that open sourced Java? Was this person's job to just do that? Why exactly she regrets it?? Because her daughter is learning Java now, but how is that regretful??
It's tongue-in-cheek. Her greatest pain of it is watching her husband and daughter hate on it through homework. ;) So the joke is that she "hates" it now because of that. (but she doesn't really hate it, she loves it.)
It was Sun Microsystems. She worked there. Her regret is about her husband being a bit annoying about it.
