Linux: How to Install Zotero Standalone (in KDE or Kubuntu)
I’ve used Zotero to manage my collection of books, articles, and other citations since Zotero was released. The software has become much more robust over time. As of the latest major milestone release (5.0), Zotero has moved to standalone software exclusively (they no longer piggyback on Firefox). With Mac and Windows, you can download executable…

Virtual Private Hosting – How to Remove a Domain with Certbot SSL Certificate (on Ubuntu 16.04 with apache)
It used to be pretty easy to remove a domain from my Virtual Private Server – dissable the site in apache, delete the files, delete the underlying database, and remove the domain from my DNS manager. Done. With SSL certificates now a standard part of hosting websites (see here), this is complicated by the removal…

Linux – 360 degree video editing on Linux
I recently purchased a 360-degree camera that I have used a few times. It takes 360-degree spherical photos and also films in 360 degrees. It’s not the most expensive such camera, but it does a decent job shooting 360-degree panoramic videos. However, I have run into a couple of problems with the resulting footage on…

R (Linux) – creating a wordcloud from PDF
On my professional website, I use wordclouds from the text of my publications as the featured images for the posts where I share the publications. I have used a website to generate those wordclouds for quite a while, but I’m trying to learn how to use the R statistical environment and knew that R can…

R (Linux) – basic installation
To install the R programming environment on Linux is pretty straightforward, but it does require a little bit of know how in order to find the correct packages. As is typically the case with Linux, there are multiple ways to get things done. I like to use Synaptic for installing and removing software, but you…

Kdenlive playhead doesn’t reposition on Linux
I use Kdenlive for editing videos when I have the occasional need to edit videos. In recent versions of Kdenlive (e.g., 17.07.70), I have been running into a problem that has been driving me crazy. The line that runs across the timeline editor, which is called the “playhead,” has been freezing in place. I could click…

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…

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…
