Well, I didn't go to my customer today, as I expected. I received a call telling me that they wouldn't be able to receive me.
Anyway, I think that today was a modestly productive day: I spent a lot of time sending e-mails dealing with bureaucratic matters (like the English proficiency exam, my quest in trying to get a financial support for my studies and a status update to advisor).
I'm really, really crossing my fingers to go to IBM's Summer Jobs, but, sincerely, I don't know what they are looking for in people applying for the positions. I guess that I should study more right now.
