So, it has been some months I last wrote on my blog. Not because I don’t have things to write, but because sometimes I’m too lazy do empty my “queue of things to write about”. Nothing better than start with one thing at a time.

Since january I’m working at ProFUSION. As before when I was mainly developing for Linux kernel and finishing my thesis (@ USP / Polimi), I’m using git a lot. Even in projects in which upstream is using a centralized approach like subversion, I simply can’t live without a local tree and thus …

Sometimes we discover that we don’t have to parallelize only the software. We must also parallelize the way it is written.

Thus, one of the last days of my graduation in Computer Engineering:

Welcome from a Linux user…

Almost a year ago I posted in my past blog (in portuguese, automated translation) a tutorial on how to use greasemonkey to workaround the ugly interface of my university’s webmail.

Just to let you all know some updates to Trissa: currently it’s in a hold state, waiting for next stable Ogre release, which is version 1.7. So until they release this version I’ll hold Trissa in a beta status, although it’s working great right now and all fixes for 1.0 are in place.

The biggest problem with current version of Ogre is that it doesn’t have proper support for multi-threaded games, or better, only one thread is able to make calls to Ogre functions which change the rendering states. In the design of Trissa …

As I did with previous projects I had at my university, I’d like to share another one: it’s a project using TinyOS. It’s mainly intended for education purposes, so if you are trying to learn TinyOS, it’s a good example to look at.

What does it do?

It’s a platform to monitor temperature and humidity of various rooms in a house. All sensors must collect data every X seconds and send them to sink, a predefined node. Sink can also change the value X and sensors may not reach sink in a single hop, so …
