At the University of Helsinki, I had a friend who was one of the open source -- it was called mainly "free software" back then -- and he actually introduced me to the notion that, hey, you can use these open-source licenses that had been around.
Tinha um amigo na Universidade de Helsínquia que era um dos do código aberto. Na altura chamava-se principalmente "software livre". Ele apresentou-me a noção de poder usar as licenças de código aberto que havia.
