Event Review: Comsolid

This week I did another presentation outside my city. This time it was at Maracanau in the Comsolid, a open source and digital inclusion event.


My first presentation was about ZFS filesystem and how you can take benefits from it like pooling storage and self healing. I used as base for examples my last post on it, Trying to corrupt data in a ZFS mirror.



My next talk was about OpenSolaris. We had a lot of questions and interesting about this. We burned some cds with OpenSolaris 2008.5 and also distributed others versions of OpenSolaris like Solaris 10.


And my last presentation was a quick talk about high performance computing, a short version on that I already did before.

Was a interesting event mainly because the public was composed primarily by young students with few background on TI. It was a challenge to present some new concepts like pooling storage for those who aren’t familiar with filesystems management. I tried to keep my talk as simpler as I could and focus on daily problems and showing that you can avoid them with some open source technologies.

Teddy e Silveira

Este é Teddy, meu cachorrinho. Ele é um poodle com menos de 2 meses. Parece uma ovelhinha e pula que nem um coelho, com as duas patas de trás. Ele adora brincar e correr atrás da gente quando estamos caminhando.

Ele só dorme do azulejo, deve ser porque é mais frio.

The main atraction at Juazeiro is a statue of Padre (Priest) Cícero with 7 meters itself and more 8 meters of base. Pilgrimage to this statue takes place in his honour every November, attracting thousands of followers. The city’s economy is highly influenced by those travelers devotes.

There’s a museum with several personal objects from Padre Cicero. People go there in order to thanks for miracles. If you got your a part of your body cured, of place there a wooden replica of that part of your body. If you got a car, you place a wooden car or a photo, and so on. There is thousands, maybe millions, of objects theres.
