Bossa Conference, an event about mobile development with free software technologies will be held on March 7th-10th in Manaus, Brazil. This year I'm speaking about using Midgard as a replicated storage layer in mobile applications, with examples for multiple programming languages and toolkits.
It is always fun to go to Brazil and meet the vibrant free software community there. The plan is to fly over this weekend, spend a few days in Sao Paulo and then head for the Amazon. Feel free to ping me if you're around.
