“Two days for hacking the Brazilian politics”
This weekend (October 3rd and 4th) will happen the first “Transparência HackDay” (“Transparency HackDay” in english), a free and open hacking event with focus on bringing together hackers, activists, managers and people with ideas to make government information/public data more accessible for everyone using and writing web tools.
I’m attending and one of my ideas is to hack CET (Companhia de Engenharia de Tráfego / Traffic Engineering Company) data and make them available. The idea is to improve a crawler I wrote (in python 
) that downloads and stores data about the traffic in São Paulo every 30 minutes from the “traffic now” CET website (as they don’t store it [or at least don't provide anything]).
