Time for a change, and a big one at that. As of September 20th, I am now a full time Employee of Ampere Computing. I am in the Software Development team, working on Open Source stuff. That means Linux Kernel and Open Stack, among other things.
I’ll post more on why in the future. Why I left Red Hat, and why I specifically chose Ampere. Both deserve a well formed explanation, as both are very important to me. My head is not there yet, it is in code and machines and processes.
I’m getting Amped.
Technical stuff has been hard to collect this summer. Having a couple weeks off hadn’t helped. So here are some pictures instead.

I don’t understand, yet, why this works, but it does. Thanks to this post
Last article I discussed the Fedora RAW file image and the first partition it contains. Now let us look at the second and third partitions.
Continue readingI was able to boot my Raspberry Pi using the Pi Imager and the Fedora AARCH64 Raw Image. While this makes me happy, I don’t really understand what these pieces are. So, I want to take a little more look at them.
Continue readingMy Day job has me messing around with QT5. We’rer building various RPMs for different RHEL and CentOS versions, and I wanted to get a little more experience on this. Specifically, I wanted to be able to do trial and error on a package that would not pollute our work stream. I wanted it to be something QT based. And I wanted it to be fun.
So I am working on repackaging QGo for Fedora 34 using QT5. Here’s what I am learning.
Continue readingWe do RPM things. Some of those RPM things need the /proc file system. Not forever, but for a short while. So we mount /proc, do something, and unmount. Which works fine.
Until we tried to do it in a container.

My musical interactions with Linux are not the most complex in the world, but they ain’t trivial. The complexity of the Linux audio landscape has been a stumbling block so far. Pipewire has just gotten me past that.
The title of this article implies that you need to do something other than install Pipewire. So far, this is not true. On my system, at least, it Just works.
Continue readingWe are trying to enable the graphics hardware subsystem on the Raspberry Pi 4. This driver lives in mesa. The current Centos mesa.spec file does not enable the V3D Driver we need. Here are the steps I am going through to build the driver and integrate it into the meta-rpm build.
