Preface: the following post was written in the context of the events that happened in September. Some time has passed, and I held off on publishing in the hopes we could reach a happy ending with System76. As time has passed, that hope has faded. Attempts to reach out to System76 have not been productive, and I feel we’ve let the impression they’ve given the wider tech community about GNOME sit fo

In multimedia, we often write vector assembly (SIMD) implementations of computationally expensive functions to make our software faster. At a high level, there are three basic approaches to write assembly optimizations (for any architecture): intrinsics; inline assembly; hand-written assembly. Inline assembly is typically disliked because of its poor readability and portability. Intrinsics hide co

As before, I was very excited when Google released VP9 – for one, because I was one of the people involved in creating it back when I worked for Google (I no longer do). How good is it, and how much better can it be? To evaluate that question, Clément Bœsch and I set out to write a VP9 decoder from scratch for FFmpeg. The goals never changed from the original ffvp8 situation (community-developed,

I suppose I can’t just leave my last post standing there as-is. I’ll start by listing a bunch of things I consider facts about the GNOME project. I don’t want to talk about solutions here, I just want to list them, because I don’t think they are common knowledge. People certainly don’t seem to talk about them a lot. core developers are leaving GNOME development. The most recent examples are Emmanu

The last few days I spent fixing up some more details in the new HTML5 gdk backend. Not everything is supported yet (keyboard input in particular is very weak), but much more things work now. Even thought the backend is not of production quality it is now good enough that I think its interesting for a larger audience to play around with. So, today I merged the branch into the Gtk+ master branch (i

The last few weeks I’ve been working on an interesting new idea, hacking out a prototype. The code is not really clean enough for public consumption yet, and a bunch of features are missing. However, its now at the stage where it can be demoed and evaluated. I think the best way to introduce it is via a video: (original theora file) [vimeo width=”763″ height=”512″]http://vimeo.com/17132064[/vimeo]

Félix Ontañón, a very good friend and hacker from my company, has just released a new versión of a systray application which help to configure and manage the Wii remote control on Linux. The application is called WiiCan and is hosted on Launchpad. The project has been programed in Python and it uses D-Bus to connect with hal (by now) and bluez for tracking the available bluetooth devices and wiimo
