Linux: Installing Redshift
There is a growing body of research suggesting that blue light before bedtime can be associated with sleep problems. I’ve known about this for a while, but have just recently started having sleep problems. I decided to try some of the programs that make changes to the color of your monitors to see if it…

Kubuntu: How to Map Windows Network Share
My workplace is largely a Windows based institution. Due to a collaborative project, I was recently asked to access some documents on a Windows Network Drive. I was sent directions for how to add that drive in Windows. Those directions were not that helpful as I, of course, run Linux. As perhaps the only Linux user…

KDE – Adjusting the Look and Feel of the Desktop and Application Windows
I love how configurable KDE is as a desktop. However, adjusting the look of the desktop is something of a nightmare. There are five different options to adjust different aspects of the desktop and application windows, each of which does different things, but the labels given to these don’t always reflect what the customizations will…

Linux – Kubuntu 16.04 with Plasma 5.5.5 – unable to change file associations
I just upgraded my laptop (Lenovo ThinkPad T540P) to the latest version of Kubuntu – 16.04 with Plasma 5.5.5. Everything was running great until I had an issue with Ark, the archiving program that comes with KDE. It was having an issue unzipping an archive. It seemed to unzip the archive, but the resulting file…

Linux: LibreOffice Print Dialog Orientation “greyed out”
I really like LibreOffice, but occasionally have to deal with bugs that cause silly regressions, like this one. For years, I have printed my LibreOffice Impress (i.e., powerpoint) slides for my students to a PDF file. The options have made this pretty simple. Click on “Print.” When the Print Dialog window comes up, click on…

Linux: Securely erasing a hard drive
I recently did some upgrading to my main desktop computer and my Network Attached Storage. As a result, I ended up moving around some hard drives and have several hard drives that are no longer in machines. I’m holding on to most of the hard drives, but some I plan on selling or giving away.…

Linux: Digikam Editor not showing images
I ran into a really weird problem with Digikam that took me a couple of days to figure out. Since it took me so long to figure it out, I figured I should note this problem here for anyone else who runs into it. What was happening is that I would open Digikam and when…

Linux: Auto Mount EXT4 partition
Several years ago I read a post in a Linux forum talking about splitting up one’s hard drive into multiple partitions so that when the inevitable reformat came along, there was no need to transfer one’s files during the process. Instead, if your files are on one partition while the operating system is on another…

Linux: remove all directories with same name
I ran into an issue with a piece of software that created hundreds of directories amidst my music and video collections. However, all of the directories had the exact same name. Rather than delete all of them individually, I figured there had to be a way to delete them all with a single command. Turns…

Connecting Linux Laptop and Android Phone to UoT_Secure
My university, The University of Tampa, is great in a lot of ways. But one thing the university fails at quite miserably is in its support of anything other than Windows. The IT department does okay in supporting Mac computers, but they don’t support Linux at all. I had to get permission to wipe my…
