  • 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…

  • LibreOffice Calc – splitting contents of cells into multiple columns (e.g., splitting commas)

    I periodically have to take a column of text in LibreOffice calc that has names like this “Lastname, Firstname” and split them into two columns. I figure it out every time, but then I forget how I did. So, here’s a quick tutorial on how this is done. Open your spreadsheet with the cells that need…

  • 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…

  • transferring some email between Gmail accounts using Thunderbird

    I have several Gmail accounts for various reasons.  Occasionally I have the need to transfer emails between the accounts.  The only way to transfer just some email between Gmail accounts is to use a desktop email client, like Thunderbird, Evolution, or KMail.  Unfortunately, the process isn’t all that straightforward and can be quite confusing at…

  • Android: Wink Hub and Sprint’s Data Optimizer

    I reformatted my Android phone (LG G3 with Android 5.0.1, software version LS990ZVG) the other day to address a problem I was having.  After reformatting, I reinstalled all of my apps and everything seemed to be working fine until I tried to log into the Wink Hub app to adjust the settings for some of…

  • 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…
