A lot of people seem not to understand very well what real-time means. They usually tend to think RT has anything to do with performance and the raw throughput. It doesn’t. It’s all about determinism and guarantees.

This post’s title has “by graphics” words. I think the graphics below are worth a thousand words. I obtained them while porting the RT tree to Freescale boards some weeks ago at ProFUSION. Basically I’m running a task that wakes up every 40ms, run a tiny job, send some numbers through the network and sleeps again. The time in …

After some time working with the EFL port of WebKit, I’ve been nominated as an official webkit developer. Now I have super powers in the official repository :-), but I swear I intend to use it with caution and responsibility. I’ll not forget Uncle Ben’s advice: ”with great power comes great responsibility”.

I’m preparing a post to talk about WebKit, EFL, eve (a new web browser based on WebKit + EFL) and how to easily embed a browser in your application. Stay tuned.

• strace traces all system calls a program does. You don’t even need the source code. Suppose a software is misbehaving and you want to know what files it is opening: all you have …

Brasil perdeu. Infelizmente estamos fora da copa.

O Juca Kfouri resumiu praticamente tudo o que eu acho desse jogo. Só pra complementar: o time de laranja era uma equipe de teatro ou de bonecas?

Last week I was officially added to EFL developers list. After contributing some patches to eina, edbus, elementary and E17 (especially to connman module), Gustavo Barbieri, who is also my boss at ProFUSION, added me to developers list giving me commit rights on EFL svn.

He said me some weeks ago that the only thing missing to add me as developer was that I’d have to use E as my window manager. Fair enough. If one wants to be a developer of a certain program, it’s better to first be an active user. So, last Friday I wiped …

And this was the Linux Collaboration Summit 2010:

I’m appearing on this video exactly at 2:00 :-D. After it shows Google giving Nexus One phones to everybody. Really nice.
