Linux – It's A Binary World 2.0

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 […]

Speed of btrfs scrub

Here’s the output of the status command: [root@supermario ~]# btrfs scrub status /media/Photos/ scrub status for 27cc1330-c4e3-404f-98f6-f23becec76b5 scrub started at Tue Mar 21 17:18:13 2017, running for 01:05:38 total bytes scrubbed: 1.00TiB with 0 errors So on Fedora 25 with an AMD-8323 (8 core, no hyperthreading) and 24GB of RAM with this hard drive and […]

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 […]

LXC Project Part 3: Starting and logging into my first container

Continuing my LXC project, let’s list the installed containers: lxc-ls That just shows the name of the container – lemmy. For completion’s sake, I’m going to start it as a daemon in the background rather than being sent straight into the console: lxc-start -n lemmy -d As per usual Linux SOP, it produced no output. […]

LXC Project Part 2: Setting up LXC

I’m continuing on from yesterday’s post to get the VM ready to host LXC. I’m starting with Centos 7 so the first thing I had to do was enable the epel repos: yum install epel-release Then, according to the guide I was following, I had to also install these package: yum install debootstrap perl libvirt […]

LXC Project Part 1: Bridging the Connection

As I mentioned before, I’m looking at Linux Containers (LXC) to have a higher density virtualization. To get ready for that, I had to create a network bridge to allow the containers to be accessible on the network. First I installed bridge-utils: yum install bridge-utils -y After that, I had to create the network script: […]

How did I not know about LXC Containers?

Back when I first was working on replacing my Pogoplug (the original BabyLuigi), I was looking at potentially using it to learn about Docker in addition to creating virtual machines that were actually useful instead of just playing around with VMs for looking at Linux distros. The benefit of Docker was to have the isolation […]

Setting up Multiple Monitors in a KVM QEMU VM

I created this video to help people learn how easy it is with Libvirt, KVM, and QEMU to have multiple monitors in your virtual machines.

Current Virtual Machines

Going to do some summer cleaning on my VMs, so I wanted to document peak KVM as a reminder of how many I had running at this time:
