While I tend to think about the nodes in OpenStack term, the people that physically move the servers around are more familiar with their IPMI address. We have several nodes that are not responding to IPMI requests. Some have been put into the manageable state, some are in error.
Here’s the query I used to list them.
If an OpenStack server (Ironic or Nova) has an error, it shows up in a nested field. That field is hard to read in its normal layout, due to JSON formatting. Using jq to strip the formatting helps a bunch
The nested field is fault.details.
The -r option strips off the quotes.

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
It took me a few tries, but I finally got a passable demo/tutorial about Pipewire and QJackCtl.
Here’s the final version. Well, final for now.
Here’s the version before that that got hit by a copyright claim and thus was not visible in Canada. I chose the “auto edit” option to remove the copywritten material. I think that means that you don’t see how you can feed browser audio back into itself. I’ve not watched it since it got cut.
Here is the original Camcorder version. This was really the approach I wanted to take, with the camera picking up the same audio that I was hearing. But the video was unwatchable.
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.
