I’ve been keeping an eye on nerdctl. While it’s still a little trickier than Docker or Podman for commands to work consistently, there’s fascinating innovation happening under its hood. One such innovation is Bypass4NetNS, the new virtual network framework used by rootless containers that’s *faster* than root kernel networking. Yes, you read that right. And…

Unfortunately, this hasn’t gotten as much attention as I think it should, but vdo volumes are now officially supported as in-tree modules in kernel 6.9 and newer. If you don’t know what vdo volumes are yet, check this out (they’re really cool). In my opinion, vdo is the best alternative to zfs‘s compression and deduplication…

flatpak search doesn’t really work, my terminal is always too narrow for the output not to truncate the name of the app, when I need the full thing in order to install it. But flatpak search -v is generally unreadable, as the descriptions are invariably longer than my terminal width, so the output ends up…

I’ve been making these images of my hard drives using fsarchiver for about 6 months, and one of the most amazing things I’ve discovered through all of it is how tiny .raw.zst images get when you run them through a compression library, whether it’s compressing them or not. Case in point: I way oversized my…

I’ve been aware of quickemu for 4-5 years now, and just went out looking for it again since I thought it’d be helpful for a project on endpoint management with Microsoft Intune. I’d like to see if I can’t set up a few devices running Windows, Mac OS, Ubunu and Redhat, remotely manage some dependencies…

You know the error messages you get any time you’re trying to pipe the output of apt to something? They’re kind of irritating since they don’t help in any meaningful way. e.g. you might want to reduce apt search results to packages that contain a string either in the name or description, but the error…

Ubuntu debootstrap for IoT maas router (Internet Gateway/firewall) – a 2-part post. Part 1: Installing Ubuntu to Thin-lvm in a Very Arch-Like Way A quick mention: I just copied this out of my plain text notes I do while completing these things. I think it’s fairly error-free, but I’ll come back and flesh it out…

So, I wasn’t so sure how soon I should write about this, but I have a fiber connection here in Seattle I’m pretty excited about. For the past decade I’d been living in Olympia, WA, where Comcast is the only game in town, and upload speeds are hampered by only having 4 channels across cable…

I thought I’d throw this up real quick, because I am constantly using for loops in bash to do batch processing, but I wasn’t as familiar about how to do them in Windows. Powershell is undoubtedly more powerful, but also incredibly verbose, so if you want to do something quick and simple like this, cmd…
