learning starts by interest, listening then reading and finally interacting
Ok I admit I have written a weird subject on this post, but I’m sick of listening (almost) everybody pronounce “posgre” when in fact PostgreSQL is pronounced like /po:st gres kju: el/; . Please follow this link and listen http://www.postgresql.org/files/postgresql.mp3
In Portuguese we call this “Chamar os bois pelos nomes” and translating this phrase is something like “Calling the bulls by its names”… or Elephants in this case. 
… so please, interact! and remember this knowledge cicle ends when you start over < subject here> but without interest!
(… this kind of stuff remembers me those guys who pronounce LaTeX like when they call a Taxi, it’s the lolocaust…)
