During this two week trip, I've been to 5 coastal cities of Brazil, and made 7 talks (5 GFv3 and 2 Hudson) and 1 hands-on-lab. I've also been to one of Hudson users' site (Fabiane's company), to see how they are using it and interviewing their experience. I'm also interviewed by JavaWorld Brazil. The audience of the talks were different from cities to cities, but overall we've reached about 800-1000 people (Hudson exposure is smaller, since I've only done 2 talks compared to 5 of GFv3). In some cities, they are mainly students, in other cities, there are more professionals.
While there were always some that are very happy about Hudson and GlassFish, I don't think the majority of the people who I met there knew a lot about GlassFish v3 nor Hudson, so it was good that I had an opportunity to talk about what's going on with these projects (it helped that Hudson is already translated to Brazilian Portuguese)
Brazilians stay up very late (it's very typical for dinners to start from 9pm or even 10pm), and in a few legs of the travel, the schedule was really tight, like we take a flight 9pm after a full day in JUG, then get in hotel in 2am, then up 6am tomorrow to go to another meet-up. But all in all it was very much fun, and we even managed to do a bit of sight-seeing.
Mauricio, who traveled with me all the ways, really took a great care of me. Food was great, and they eat a lot of lot of red meat (so don't send any vegetarian down there, or they'll starve.) They have a dozen different names for different parts of beef, and they know which is which just by looking. So they take their red meat very seriously. There were also many fruits that I've never seen before anywhere else. They had an ice cream made of corn, and it actually tasted good, and I had more ice creams there than I normally ate during an entire year.
People drive like crazy, as if there are no such things as traffic lanes. People have apparently developed some signal languages (by using honking, blinkers and hazard lamp), like "get out of my way" or "I've got the right of the way." Some traffic lights are like those in the racing circuit, so that you know exactly when it becomes green, which helps people drive like a drag racing in public roads (it also tells you how many seconds are left until it turns red, so that you know when to gun the traffic light and when not to.
People apparently don't travel that often in air, so most airports are small, and many flights make multiple stops like buses do. I saw one flight that makes 3 stops before it gets to its final destination.
All in all, I enjoyed a travel a lot. I'd love to be given an opportunity to visit there again.
