To reinstall a machine that is managed by IPMI, you tell it to PXE boot and then power cycle. Here are my notes.Continue reading
Dad gave me back the lathe I gave him….he has other toys. Including a production system for firewood. So I got same maple (I think) and rough turned some bowls.Continue reading
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.
I 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 reading
My 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 reading
git archive --format=tar.gz -o ~/neptune3-ui-5.15.tar.gz 5.15 --prefix=neptune3-ui-5.15/
These are the options I needed. the -o says where to put the file, and the –prefix (with the / at the end) puts it in a subdir.
We 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.Continue reading
Just wanted to leave myself a note here. On QJackCtrl It shows the latency in the bottom right of the Parameters page. If I drop the Frames/Period to 16 (Lowest) the latency drops to 1 msec. For a Jamulus server with a ping time of 22ms I get an overall delay of 44 ms.
And that is over wireless.
This is on my laptop, not my NUC, and it does not have the Scarlet Solo USB Analog-to-Digital converter on it.
But it is encouraging.
