Based on the file modification dates, I went from using the Digikam SQLite database to using their embedded MySQL database in May 2018. I did it because at the time everyone was saying that for a large database it’s better to use SQL than SQLite. For a long time it seemed to work well enough […]

Addendum to my KDevelop Post
A couple days ago, I wrote about giving KDevelop another look and posted it to reddit’s r/kde. In my post, I’d said it was annoying to have to configure the color schemas per file. Someone commented on the subreddit that if you use the View->Schema menus it’s per file while if you go into Settings->KDevelop […]
Red Hat Summit 2019
Red Hat Summit 2019 was my first Red Hat Summit. I heard quite a few people saying it was the largest one they’d been to yet and that it used to be a pretty small convention. That was not the case this year; it used up the entire Boston Convention Center. I’ve said before, concerning […]
Upgraded Laptop to Fedora 30
Now that I’m back from Red Hat Summit, I am ready to start upgrading my Fedora computers. Well, probably not the server or the living room HTPC – I’ll take advantage of the fact that Fedora supports the n-1 release to reduce headaches and downtime. As I’ve done for a few releases now, I used […]
The self-hosting journey continues
Although I’ve had a website since the mid-90s, it was 2005 or thereabouts that I first started hosting my own sites rather than relying on other sites. The first bit of hosting involved blogging and I tried a few different software packages before settling on WordPress. And other than playing around with phpBB for my […]
CentOS 7 works on Acer Aspire One D255E
Often people try and dissuade you from installing CentOS onto a laptop because they say the chipsets on the laptops are so varied it’s likely you will end up unable to use your laptop because the drivers aren’t there. Well, I don’t know if it’s because this netbook is so old (I mean, netbooks as […]
Attempting to use Clonezilla to clone my server
My main server, Tanukimario, has a 120GB hard drive in it and it’s started to become annoying to butt up against that limit. I have an 512GB SSD that I only used for a couple years that I wanted to use as a replacement. In order to reduce the annoyances that come from setting things […]
HDRMerge and CC Extractor RPMs
A while back I created a copr repo for HDR Merge. I hadn’t kept up with it because there weren’t regular HDRMerge releases going on, but I noticed the git repo has been very active, so I decided to create a new RPM for Fedora 29. And recently I learned that for the newest version […]
Another piece falls into place for Docker
Yesterday I was at a conference dedicated to DevOps and so Red Hat and Google were there to talk about containers, especially Docker and Kubernetes. While summarizing it to some of my employees today, I was asked about what I see as the benefits of Docker containers relative to Virtual Machines. I mentioned that one […]
Current favorite thing about KDE with Kmail setup
Hitting alt-F2 then typing email (contact name – eg Danielle) and enter and then it presents me with an email window to send an email. No need to navigate to gmail.com or go over to the screen running Kmail (actually, usually Kontact).
Stratis or BTRFS?
It’s been a while since btrfs was first introduced to me via a Fedora version that had it as the default filesystem. At the time, it was especially brittle when it came to power outages. I ended up losing a system to one such use case. But a few years ago, I started using btrfs […]
Using Docker Now!
With modern technology, here’s the pattern I’ve noticed since college. New tech comes out and I can see that it’s neat, but not how I can make use of it. A few years later, I finally come across the right article and it all makes sense to me. I first noticed this with VMs. I […]

Finally have btrfs setup in RAID1
A little under 3 years ago, I started exploring btrfs for its ability to help me limit data loss. Since then I’ve implemented a snapshot script to take advantage of the Copy-on-Write features of btrfs. But I hadn’t yet had the funds and the PC case space to do RAID1. I finally was able to […]
