Hello. My name is Silveira Neto. I'm a Brazilian student in the master's degree program in Computer Science at George Washington University in Washington DC, USA. I'm also consultant at the Inter-American Development Bank. Previously, I worked at Sun Microsystems, Casa Brasil and Atlântico Institute. This is my personal blog for technologies and random stuff.
Be careful with reflection! :)
