1. Given enough eyeballs, all bugs are shallow

    So, in last post I said kmod 2 could be released sooner than expected if there were major bugs. Not as much as a surprise, there was 1: depending on the alias passed to the lookup function we were blocked iterating a list.

    It’s now fixed in git tree. Thanks to Ulisses Furquim for fixing it and Dave Reisner for the bug report. We already have some other great stuff implemented so we’ll soon have another release.

    Another great news is that now we have the maintainer of module-init-tools (Jon Masters) cooperating with us. We will discuss how …

  2. ANNOUNCE: kmod 1

    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.


    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 …

  3. 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 …

  4. 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 …

  5. 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 …

  6. ANNOUNCE: codespell 1.2

    Since I created a mailing list for codespell, the announcements here will not have as many details as before. Checkout the new version of codespell: http://groups.google.com/group/codespell/browse_thread/thread/bce1a6f83d4bbd85

    One of the issues I with codespell was that it was trying to parse cscope.out, since it’s a text file. On Linux Kernel this file can get very big and besides taking much longer, sometimes it was running out of memory :-). Now codespell has an option to ignore files, even text ones. It’s as easy as passing —skip=”*.eps,cscope.out” (notice …
