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…

LibreOffice Calc – Search for Specific Text Across Columns
I have a task I am asked to do fairly regularly that involves searching through a large spreadsheet (around 4,000 rows with about a dozen columns) looking for very specific text. There are, of course, various ways I could accomplish this. But I finally found a solution that speeds this up and want to document…

Batch Convert MP4 to MKV
I ran into an issue where a number of my MP4 files on my fileserver were stuttering when I tried to play them back using Plex on my TV. After a lot of googling, I found out that this was due to some header information in the MP4 files and that the simple solution was…

FreeCAD Import STL
I’m not a FreeCAD expert. I bought a 3D printer and am constantly coming up with new ideas for 3D prints to solve issues around my house and office. That required me to begin learning how to use CAD software and, as an open-source advocate, FreeCAD was the obvious choice for CAD. I design most…
