I recently spent a couple of days in London talking to a .Net customer about Java Enterprise Edition architecture and development.
It was really interesting to share views and experiences with these guys. I realized how much the architecture and the concepts are close to each other, altough our vocabulary differ.
One night, the customer convince us to take the tube (for US-only guys : the tube is the UK subway system) to enjoy a dinner downtown.
It’s difficult to travel in there without thinking about what recently hapened but people continue to live and work as before, even at night, the car was crowded. Security is impressive as well : armed police officers and (pre-attacks) video camera are everywhere.
