  • X11 mode-line generator

    I recently installed NetBSD-current (4.99.12 at the time I did this) inside Parallels Desktop for Mac. Everything went fine except for the configuration of the XFree86 shipped with the base system: I was unable to get high resolutions to work (over 1024x768 if I recall correctly), and I wanted to configure a full-screen desktop. In my specific case, this is 1440x900, the MacBook Pro's native resolution. It turns out I had to manually add a mode line to the XF86Config file to get that resolution detected.

  • Building the libspe2 on the PS3

    The Linux kernel, when built for a Cell-based platform, provides the spufs pseudo-file system that allows userland applications to interact with the Synergistic Processing Engines (SPEs). However, this interface is too low-level to be useful for application-level programs and hence another level of abstraction is provided over it through the libspe library. There are two versions of the libspe: 1.x: Distributed as part of the Cell SDK 2.0, is the most widely used nowadays by applications designed to run on the Cell architecture.

  • NetBSD and SoC 2007

    Yes, ladies and gentlemen: Google Summer of Code 2007 is here and NetBSD is going to become a mentoring organization again (unless Google rejected the application, that is)! We are preparing a list of projects suitable for SoC; spend some time looking for one that interests you (I'm sure there is something) and get ready to send your proposal between the 14th and 24th of this same month. I've already made my choice :-)

  • Article on Multiboot and NetBSD

    A bit more than a year ago I started working on Multiboot support for NetBSD. This work was completed by the end of past year and was integrated into the main source tree, allowing any user to boot his NetBSD installation by using GRUB alone, without having to chainload different boot loaders. I've written an introductory article on Multiboot and how NetBSD was converted to support it. It has just been published at ONLamp.

  • ICB support added to Colloquy

    Internet Citizen's Band (or ICB) is an ancient chat protocol, most likely the precursor of IRC. It is very limited — for example, you can only be logged into a single room — but I need to use it to communicate with a group of developers. It has a nice feature, though: bricks! Those who have used it know what I mean ;-) Up until recently, I used the ircII console client to access this chat network.

  • PFC subject chosen

    A while ago, I was doubtful about the subject of my undergraduate thesis (or PFC as we call it). At first, I wanted to work on a regression testing framework for NetBSD. This is something I really want to see done and I'd work on it if I had enough free time now... Unfortunately, it didn't fit quite well my expectations for the PFC: it was a project not related at all with the current research subjects in my faculty, hence it was not appropriate enough to integrate into one of these work groups.

  • Mac OS X aliases and symbolic links

    Even though aliases and symbolic links may seem to be the same thing in Mac OS X, this is not completely true. One could think they are effectively the same because, with the switch to a Unix base in version 10.0, symbolic links became a “normal thing” in the system. However, for better or worse, differences still remain; let’s see them. Symbolic links can only be created from the command line by using the ln(1) utility.
