Este mês, nos dias 2 e 3 e Outubro ocorreu o LXJS 2013 no cinema São Jorge com speakers bastante interessantes que trabalham na Mozilla, Adobe, Triumf, Sauce Labs e Google. E muito outros com produtos, experiência e casos interessantes para partilhar!

O LX JS 2013 foi organizado por voluntários e com a ajuda dos vários sponsors, conseguiram reunir uma conferência muito bem estruturada e que, na minha opinião, correu lindamente, sem grandes atrasos e apenas com um projector um pouco desfocado no primeiro dia que trataram de arranjar solução e que ficou tudo óptimo no segundo dia. Passaram as apresentações em live streaming e colocaram tudo também no youtube (só não encontrei duas...).

Adorei a conferência! Foram dois dias inteiros cheios de apresentações que vou partilhar aqui, com algumas notas e links que tirei na altura, que estão nos vídeos mas como são 37 facilita a identificação do que falaram mais facilmente.
