Ever since I’ve switched from Gnome to DWM on my main laptop, I have to perform most things on command line now. I know, right? :P Anyway, I need to pair a bluetooth mouse, Logi MX Anywhere 2S, with this Fedora laptop. I had a similar post a while back about connecting Bose QC35 to Fedora 29. So this is quite similar to that post. First, ensure that bluetooth.service is running:...

While newer version of a package on Linux system is generally a good thing, and we should upgrade it, there is times when we should hold on to the older version. For instance, Fedora 32 just released a newer version of the kernel package 5.8.4 recently, and with this version, the zfs module, version 0.8.4, can’t be built. Therefore, if your Fedora system uses ZFS, like some of my machines, you’ll end up not seeing any ZFS dataset or pools....

I’ve been meaning to pick up a micro-controller and work on it again. About 5 years ago when I first encountered Arduino, I spent sleepless night learning about it, and creating things from DIY weather station, world clock, light sensor, etc. Fast forward to the current days, I almost forgot everything I learned. But we can always re-learn, or can’t we? Tonight, I found an Stm32 Nucleo F401RE micro-controller, and I want to start by updating the firmware on it (admittedly, this is the easiest thing to do)....

On most my systems I created a user called devops with its home directory created at /srv/devops. And on Fedora or CentOS systems, those home directories have their SELinux context set correctly when created. Recently, I found out that on all 3 machines so far, the SELinux context has been reverted. ~# ls -lZ /srv total 0 drwx------. 5 devops devops system_u:object_r:var_t:s0 127 Oct 30 2019 devops It should have had the same context as the normal user kenno in /home directory:...
