LibreOffice – Create Custom Color Palette
(This is for LibreOffice version 24.2.7.2 on Kubuntu 24.04.) I know I’m weird in a lot of ways (I mean, who still blogs in 2025?!?), but here’s a new one. I create lots of charts and graphs as well as presentations for classes. I tend to prefer a minimalist approach – white background with black…

AppImage, Snap, and Flatpak on Kubuntu
I’m guessing most people who don’t use Linux have no idea how convenient repositories are. I’m a huge fan of how Linux has managed (and mostly continues to manage) software for quite a while: you open a console or the software manager on your computer, search for the software you want, and install it. The…

Kubuntu 25.04 – KRunner and iBus issues
Over the last month, I have updated the three computers I use to Kubuntu 25.04. On my laptop, I ran into an issue where Wayland would just periodically freeze. I figured out a solution to that and detailed it here. I finally installed Kubuntu 25.04 on my home desktop, which is the machine I use…

Convert Text to Audio on Linux – Coqui TTS
In a separate post on my blog, I documented a simple way to convert text to audio using Google’s Text-To-Speech service. This works for small projects. But, during a recent conversion, I ran into an error where my requests were getting blocked by Google for using the service too much. I didn’t realize they capped…

Best 3D Printed Sunglasses Clip for Car Visor
I’ve needed a place to put sunglasses in my car for years. My sunglasses have typically ended up in one of the cup holders. Recently, it dawned on me that I could print a clip or holder that would attach to my sun visor to hold my sunglasses. I looked at the various 3D design…

Redacting PDFs on Linux
I had an odd situation pop up where I needed to redact a PDF. It wasn’t anything nefarious or super exciting, but it did involve a complicated PDF that included images and tables in addition to text. In figuring out how to redact the PDF, I ended up learning a few things and thought it…

Fixing Zotero Corrupt Database Issue on Linux
I use Zotero to manage my references and have for decades since it was first developed. I’m a huge fan and teach all my students how to use it. But I also don’t follow one of the programmers’ recommendations on where to store my Zotero database. As soon as I install Zotero, I change the…

Kubuntu 25.04 – Reset Wayland
I just installed Kubuntu 25.04 on my laptop and started running into an issue. It started when I tried to load Spectacle to take a screenshot. Spectacle froze and so did my panel, but I could still hit Alt+F2 to open new programs. I could also use Alt+Tab to switch between non-frozen programs. I couldn’t…

Changing Default Browser for Links in Thunderbird
I just reformatted my computer (I try to do that about once a year) to Kubuntu 25.04. That meant setting up Thunderbird (version 128.10.0esr) with my email again. I use Firefox as my default browser (because it respects privacy), but install Chromium as a backup for the occasional website that doesn’t work very well with…
