I thank Lord who may allow me to live in academia, really. Today, I have got many offers of interests in my visiting and giving a talk in UK this summer. Many friends and mentors to me extend their hands to help and support me. When I was in twenties and early thirties, I've never ever imagined I would be able to travel around the world and enjoy discussions with those people working in the front of computer science. I was a late comer there. I was already twenty eight when the grad school allowed me to the M.S. program. It was a nightmare to be laughed at in classes full of the very much younger. Some of them were so nasty and annoying me. But now all of people around me are very helpful and eager to support me in sharing their doing in computer science to each other. I'm really happy to thank God and appreciate them to accept me as a buddy.
