R – Finding and Setting Working Directory
R, like many software programs, likes to have a folder or directory on your computer to operate in. When you start R, depending on how you start it and whether or not you previously saved your session, it’s likely that R will set a default “working directory” or folder where it is going to look…

Launching HandBrake 1.4.0 in Kubuntu 21.04
The fine folks at HandBrake have updated their software and distribution system to a Flatpack approach. Their Flatpack for Linux is based on Gnome, not KDE, which is fine, but it does mean that the GUI is no longer skinned with my system settings on KDE. Oh well… The bigger issue is that, with a…

Linux FFMPEG – Flip Vertical Video to Horizontal
I was recently shooting some videos on my phone to share with someone else and accidentally flipped the phone before filming a clip. I never film vertically as I know that our playback devices are not designed to playback vertical footage. But I screwed up and got a clip that was vertical. Since I would…

Linux – Batch Convert .wav to .flac
I ran into a weird issue the other day where SoundConverter, a GUI for converting audio files, was generating flac files that my audio player couldn’t see. I’m still not exactly sure what the problem was, but in trying to solve the problem, I went ahead and wrote a command to batch convert a folder…

LibreOffice – KDE Integration Package for Skinning/Color Management
Super simple note for future reference and for anyone else running into this issue. I upgraded my version of LibreOffice in Kubuntu 20.10 to a pre-release version to fix a bug.

Linux Server – tar files and directories
I recently had to move all my websites from one virtual private server (VPS) to another. When I only had a few such websites, I was okay with using SFTP (via Filezilla) to download all of the files and then upload them to the VPS. It took a while but I was okay with that.…

Linux Server – Adding a New Domain and WordPress Site – Linode VPS – Ubuntu 18.04
I have a VPS server with Linode that I use to host about a dozen different websites. All but one of them run on WordPress. Occasionally, I get a request to add another domain and website to the server. It’s not terribly time consuming to do, but it does require a number of specific steps…

Long Term Storage of Gmail/Email using Mozilla’s Thunderbird (on Linux)
I have email going back to 2003. There have been times when I have actually benefited from my email archive. Several times, I have gone back 5 or more years to look for a specific email and my archive has saved me. However, my current approach to backing up my email is, let’s say, a…

Linux – Bulk UnRAR
If you’re not familiar with RAR files, they are like ZIP files. RAR is an archive format. I had a collection of more than 150 RAR files in a single folder I needed to unrar (that is, open and extract from the archive). Doing them one at a time via KDE’s Ark software would work,…

Linux: Batch Convert .avi files to .mp4/.mkv
I’ve been trying to clean up my video library since building my latest NAS. In the process, I found a number of .avi files, which is an older file format that isn’t widely used these days. While every time a file is converted it loses some of its quality, I was willing to risk the…
