  • 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

    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:

  • Using Flatpak to install LibreOffice on Fedora 24

    After someone told me that a PDF I’d created in Calligra Office was illegible and having issues with spreadsheets loading slowly, I decided to install LibreOffice. However, rather than go with the version in the repos, I decided to go with Flatpak – which allows for a more advanced version via the usage of runtimes.…

  • SuperMario is at Fedora 24

    My main computer is now on Fedora 24. This time around I only had to uninstall HDR Merge (which was from my COPR and I hadn’t built a Fedora 24 version yet) and OBS-Studio because there isn’t a Fedora 24 package for it yet. Not bad. After rebooting, I didn’t have graphics. Then rebooting once…

  • Fedora 24 is out!

    Fedora 24 is out!

    Fedora 24 was released yesterday. I updated Daisy, my big laptop, first since it’s not critical. If the update broke something I wouldn’t care. The only hitch it had was that I had to reinstall the RPMFusion repos from the RPM for Fedora 24. Otherwise it was saying that one of the packages wasn’t signed…

  • Tomahawk – unify all your cloud and local audio

    Tomahawk – unify all your cloud and local  audio

    It’s been a long time since I last took a look at an innovative music player. Back in 2006 I explored Songbird ) and in 2008 I looked at some of the unique features over two posts: Taking Another Look at Songbird and Play the Web. The ability to grab MP3s off of sites, in particular…

  • Exploring Rockstor

    I’ve been looking at NAS implementations for a long time. I looked at FreeNAS for a while then OpenMediaVault. But what I really wanted was to be able to take advantage of btrfs and its great RAID abilities – especially its ability to dynamically expand. So I was happy when I discovered Rockstor on Reddit.…

  • Black and White Conversion Challenge Round 1

    Now that Google has released the Nik Collection for free, I wondered which is the best way to convert a color image into a B&W image. So I wanted to compare the results from RawTherapee, GIMP G’MIC Plugin, and Nik Collection in Photoshop. What follows are four videos as go through the processes. Here are…

  • Removing an Object from a Photo in GIMP

    Removing an Object from a Photo in GIMP

    You might remember the photos from Scarlett’s birthday party. For some reason Dina wanted to hide when holding Sam. Her shoulder and back ended up being incredibly distracting in the photo. It would have been better if she would have just stood up and held him normally rather than pretend he was sitting on his…
