FM Radio Tuners in Feisty

I upgraded to Feisty about a month or so ago, and it has been a nice improvement so far. One regression I noticed though was that my USB FM radio tuner had stopped working (or at least, Gnomeradio could no longer tune it).

It turns out that some time between the kernel release found in Edgy and the one found in Feisty, the dsbr100 driver had been upgraded from the Video4Linux 1 API to Video4Linux 2. Now the driver nominally supports the V4L1 ioctls through the v4l1_compat, but it doesn’t seem to implement enough V4L2 ioctls to make it usable (the VIDIOCGAUDIO ioctl fails).

To work around this, I ported the tuner code in Gnomeradio over to V4L2. The patch can be found attached to bug 429005. I don’t know if this patch will go in as is though, since it only works for drivers supporting V4L2. Perhaps it’d be worth supporting both APIs, using V4L2 if both are supported.

Launchpad 1.0 Public Beta

Today we unveiled the Launchpad 1.0 User Interface, which has been in private beta for the last few months. As well as the improved visual appearance, there are a number of new features such as the ability to add your own branding to Launchpad pages associated with your project (for example, Ubuntu’s pages).

As mentioned in the press release, we’ve got two new high profile projects using us for bug tracking: The Zope 3 Project and The Silva Content Management System. As part of their migration, we imported all their old bug reports (for Zope 3, and for Silva). This was done using the same import process that we used for the SchoolTool import. Getting this process documented so that other projects can more easily switch to Launchpad is still on my todo list.

As Launchpad is a user of Zope 3 technology, it is great being able to provide the bug tracking infrastructure for the project. It should also make it easier to collaborate on bugs that affect both Launchpad and Zope.
