  33. Cees de Groot

    Apply technology and methodology to help people connect, spaceshift, timeshift, network. If the technology doesn't help, don't apply it. Sometimes, paper and pencil is the most appropriate technology. The technology is always just the means, never the goal - I'm very disloyal to products and technologies if they don't prove their salt's worth. Among others, I dropped 4GL's, Bad OO (C++, Java), fat&static client/server, stupid distributed systems (Corba, J2EE); I did not drop (so far) . . .
