This is one of many short video segments which will be added to the Digital Tipping Point (DTP) archive.  This interview features Flavio Santino, a security teacher with 4Linux, a Brazilian company founded by Marcelo Marques, which provides services in supporting and deploying Linux in enterprise-level businesses. We interviewed Flavio primarily because he is such a good teacher that he makes his students laugh until they cry. Or at least we laughed until we cried while watching his class, and we didn’t even understand Brazilian Portuguese. 4Linux will be used in our film as an example of ways that companies are making money with "free" software. Some of 4Linux's clients in Brazil include IBM and Mercedes Benz, if I recal correctly. We will update this description after we get a transcription and translation of this segment.
