Just a few a days ago, I wrote a blog post about Pairing Bluetooth Mouse on Command Line on a Fedora laptop. So why do I need to write another post about doing the same thing on Gentoo? Well, as it turned out, I need a bit more than just turning on the bluetooth service and pairing the mouse. My Gentoo’s installation is very minimal, and I think this gives me an excuse to document on how I’d solve or get this working on Gentoo. ...

One of my virtual machines runs out of disk space in the root (/) partition, and I want to remove the /home partition and using this free space to resize the root partition. Nowadays, for any serious systems, I’d use LVM with XFS on top. However, for this test VM, I have a virtual disk with 4 partitions without LVM. Managing partition on LVM is much easier than working the disk partition directly. I can’t remember the last time I had to do this, so here is something to remind my future-self if I need this information again. Hey, if you’re reading this now, this might be useful to you too. ...

The exam was 4 hour long. I managed to finish all questions in 3 hours. Fortunately, I found a mistake in the last hour. I think the EX415 exam wasn’t too difficult and pretty confident that I did well. The most difficult part: not knowing what I did wrong. Or how the marker scripts would like to see our answers. I suspected there was a mistake in a question, but who to ask since there is a NDA? If you’re reading this, I can’t even ask or share this suspicion with you. (Again, because of the NDA.) ...

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: ...

On Fedora or CentOS, on way to find out what package providing a file we can use yum whatprovides [FILENAME] or dnf whatprovides [FILENAME] on a DNF-aware system. # dnf whatprovides tmux Last metadata expiration check: 2:33:06 ago on Wed 09 Sep 2020 09:45:07 PM AEST. tmux-3.0a-2.fc32.x86_64 : A terminal multiplexer Repo : @System Matched from: Provide : tmux = 3.0a-2.fc32 tmux-3.0a-2.fc32.x86_64 : A terminal multiplexer Repo : fedora Matched from: Provide : tmux = 3.0a-2.fc32 I really need this similar tool on Gentoo, and it looks like the emerge command doesn’t have this function built it. Fortunately, there is a utility called e-file (provided by pfl package) which kinda provides this whatprovides option as in yum and dnf. ...
