Essa semana participei do XXIX ENECOMP em Vitória da Conquista – BA. Fui muito bem recebido pelos organizadores e pelos alunos que participavam do evento, todos bastante motivados a aprender e trocar experiências. Foi bacana também o contato com os outros palestrantes, as conversas no fim de tarde renderam conversas bem agradáveis e boas risadas.

Em minha participação ministrei um mini-curso de desenvolvimento de aplicativos para Ubuntu Touch, e dei mais duas palestras: uma contando um pouco das minhas experiências como desenvolvedor de software livre e outra demonstrando um pouco de programação declarativa com Qt e QML. Prometi aos meus alunos que disponibilizaria os exercícios e mais alguns links, então aí vai:

Aproveitando, gostaria de agradecer aos organizadores do ENECOMP pelo convite e por toda a atenção durante o evento, foi muito gratificante participar do evento, e espero ter correspondido às expectativas!


Small Projects Collection

Long time no post…

While doing some cleanup in my home folder, I found some few applications I have started but never finished. So I decided to put all of them online so that people can check and (maybe) use the code for something more productive than being forgotten in the middle of many other disorganized files.

The programs are very simple (don’t expect any Ooohhh application there) but as I had fun doing them I hope you enjoy.

Check them out!

Yafaray using Qt

Yafaray is the development version of the open source rendering suit Yafray. The code structure has been totally reviewed and it has gained many new features.

Some time ago I have written an experimental Qt GUI for it (yafaray-qt) which was already fully functional (allowing for loading XML scene and saving them to the image formats supported by Qt itself). Some weeks ago this interface became the official yafaray UI (even if using it as a blender plugin):

It is very basic for now, but it does its job already. There are plans for adding more stuff on it, but for now it will stay like that for awhile.

As soon as Mandriva Cooker reopens for development I’ll create a package for yafaray and make it available for testing. For those interested in trying it before that, here is the announcement.

Photo Viewer

Some time ago, I was looking at the INdT’s Canola interface, and I found it really nice. Its look is very clean and the way it displays the contents fits very well in the target devices.

By this time, I was wondering how hard it would be to create an image viewer like the one present in Canola using Qt. To try this out, I started a toy project using Qt and exiv2. It is a very basic image viewer interface that just displays images in a similar way to the Canola interface.



It is very basic and experimental, but for the ones interested on it:

svn co

Have fun 🙂
