1. LinuxCon Brazil

    I’m back from LinuxCon Brazil, that was held in Sao Paulo on 17 and 18 November. Before the first keynote, ProFUSION was announced as becoming member of Linux Foundation :-)! Our logo is already in their members page.

    It was also a great time to talk again to some developers I met in LinuxCon Europe last month and some that were not present there. One talk I really like was given by Eugeni Dodonov about the Intel Linux Graphics stack. It was a good overview of all the graphics stack in Linux, paying attention to Intel’s boards and drivers …

  2. Back from Kernel Summit, LinuxCon Europe and ELCE

    Last week from 23-Oct to 28-Oct I was at 3 conferences in Prague, Czech Republic, together with Gustavo Barbieri, Gustavo Padovan and Ulisses Furquim: the ProFUSION crew in Prague.

    Starting from Kernel Summit, I had the opportunity to join the Bluetooth Summit and participate in the discussions regarding this subsystem in Linux, both in kernel and user space. We had a lot of hot topics to discuss, including the upcoming BlueZ 5.0, Bluetooth 3.0 (high speed), Bluetooth 4.0 (low energy) and I could also demonstrate the work I’ve been doing with the AVRCP profile. I’m …

  3. AVRCP 1.3 on BlueZ

    During the past weeks I’ve been working again on the BlueZ project and now we can finally announce that the AVRCP 1.3 profile is officially supported.

    Technical background

    For those who don’t know what I’m talking about, here comes a little background for those buzzwords:

    BlueZ is the user-space part of the Bluetooth® technology stack used on Linux and Android. It has support for several Bluetooth profiles such as RFCOMM, HID, PAN, PBAP, OBEX, HFP, A2DP (some of them are implemented as separate projects) that are defined by the Bluetooh SIG. In simpler terms, BlueZ is …

  4. ANÚNCIO: genslide 0.3

    É com satisfação que anuncio a primeira versão do programa genslide, genslide 0.3. É um simples programa que criei para facilitar a conversão de letras de música em slides, salvando-os em pdf através de Latex/Xelatex. Esses slides podem ser usados durante shows e cultos e venho usando-os já faz 6 meses na igreja que eu frequento. Embora ainda tenha bastante coisa para ser feita, ele já se mostra bastante útil e facilita bastante na hora de criar novos slides.

    A ideia é que o usuário não se preocupe com muito com a formatação, apenas com a divisão de …

  5. Criando imagens customizadas de endereços de email

    Endereços de email são muitas vezes mascarados na web para que não sejam facilmente obtidos por programas que tem por objetivo enviar spam. É relativamente fácil escrever um programinha que fica vasculhando a web em busca de endereços de email, cadastrá-los em um banco de dados e depois utilizá-los como quisermos. Para que isso não ocorra, várias vezes nos deparamos com endereços de email passados como “joao AT gmail DOT com” ou alguma coisa do tipo.  Outra técnica muito utilizada é transformá-lo em uma imagem. Dessa forma o programinha malicioso que a princípio era fácil se torna bem mais difícil …

  6. Easily embedding WebKit into your EFL application

    This is the first of a series of posts that I’m planning to do using basic examples in EFL, the Enlightenment Foundation Libraries. You may have heard that EFL is reaching its 1.0 release. Instead of starting from the very beginning with the basic functions of these libraries, I decided to go the opposite way, showing the fun stuff that is possible to do. Since I’m also an WebKit developer, let’s put the best of both softwares together and have a basic window rendering a webpage.

    Before starting off, just some remarks:
