For some weeks now I and Gustavo Barbieri at ProFUSION have been working on a new library and a set of tools, libkmod and kmod respectively. This is the announcement of its first public release.

Overview

The goal of the new library libkmod is to offer to other programs the needed flexibility and fine grained control over insertion, removal, configuration and listing of kernel modules. Using the library, with simple pieces of code it’s possible to interact with kernel modules and then there’s no need to rely on other tools for that. This is a thing lacking on …

Hoje dei uma palestra na AndroidConf sobre “Modificando a API do Android”. Referências ao projeto que falei sobre AVRCP podem ser encontradas em um post meu anterior. Estou disponibilizando abaixo os slides.

EDIÇÃO 02/12/2011: coloquei uma nota no slide 7, relatando o que falei durante a apresentação sobre uso de IDE.

Para aqueles que não conseguem visualizar acima, segue o link direto para a apresentação.

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 …

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 …

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 …

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 …
