About me

I'm a software developer and systems administrator working for the Brazilian government, MSc in Computer Science by UFRGS on signal processing with a focus on parallel audio processing on the GPU. I have worked with the Microsoft Windows API for years and back then I did all my projects in C/C++. In my current job, I spent 2 years working with Linux servers and network equipment, having learned bash, Python, MySQL, LDAP, etc. One year later I switched entirely to using Ubuntu (Xubuntu actually) and sometimes Mac OS X. I've been working with Java web frameworks since 2011, but at home I use a lot of different stuff.

I love travelling. It started when I went to Canada in 2009 to present the subject of my Master's thesis. It was my first time outside Brazil. Since then, I've been to 18 countries and about 60 foreign cities in 4 big trips – in North America (2009): Canada and bits of the US (Seattle and NYC); in Oceania (2010): New Zealand and Australia; in Europe (2011): Spain, Switzerland, Austria, Italy, Germany, Belgium, Netherlands, Sweden, France and the UK; in Latin America (2012): Argentina, Chile, Peru, Uruguay. The next trip (2013) will be to Asia: Japan, South Korea, China and maybe somewhere else in southern Asia. And the list ahead is huge, including Brazil itself (the Northeast), Eastern Europe, Antarctica, India, the Middle East and Africa.

One thing I learned from my trips is that Brazil is not as bad as it is often depicted, and the country is changing fast (not as fast as South Korea or China though). Brazil has significant infrastructure problems and seriously lacks resources for the independent tourist, starting with a decently up-to-date electronic map, which would help avoid most of these problems. It was my trip to Argentina that introduced me to OpenStreetMap, since the project really took off there. Unfortunately, I don't expect Brazilians to pick up that trend so soon (the learning curve is too steep), and I don't expect help from the government either (for lack of political interest). I hope that will change when the basic work gets done and people realize the practical advantages. I see that, as long as the data remains free and open, OpenStreetMap has the potential to become an urban planning tool as well, serving both the government and the population, helping them see clearly and resolve the system's deficiencies. Moreover, in preparation for the World Cup (2014) and the Olympics (2016), there is a lot of construction work going on and many ways have changed, making most commercial navigation units in the market useless. The best ones haven't been updated in my area for the last 2 years. Bad for residents and for visitors. But with OpenStreetMap, I quickly fixed the routes along all places I visit regularly and now it's the best resource available for local route planning.
