  • This is a very personal question, and it’s really just whatever you are comfortable with. I personally:

    • Try to be open about it and my experiences with friends, if only because I’m sure people had suspected I had it and I so wish someone had mentioned it. I’m willing to cut friendships if I’m judged negatively, but ADHD is common in my social circles so it hasn’t been a huge issue.
    • Have been debating with my ADHD siblings how to broach the subject with my definitely ADHD parents. It’s definitely common among my extended relatives, but I just feel it’s not worth the fight.
    • Would be very guarded in a workplace. Accommodations for ADHD are hilariously trivial asks, but I’m skeptical I’ll ever work somewhere I can (safely) get them.
    • Try to avoid the subject with older generations.


  • I’m not going to watch the video, but what’s the procedure for switching between Linux and Windows? Usually you dedicate a GPU entirely to VFIO, with a 2nd GPU for the host OS (or run headless).

    Anyway, will it work? Yes, minus some anti-cheat software. Will it be a simple solution? Well, once you get things stable, yes. The tech behind this is mature, but it can be a rabbit hole.

    I would look into a non-Nvidia GPU for your 2nd PCIe x16 slot (x4, shared with the 2nd M.2 slot FYI). Good idea to check IOMMU groups before buying anything, but modern AMD motherboards are usually fine. Blacklist the Nvidia drivers and dedicate the 3070 to VFIO to make your life easier, and run Linux off the secondary GPU. Intel A380 might be a good choice. Do gaming stuff on Windows and stream via Parsec/Looking Glass/Moonlight+Sunshine; everything else on Linux.


  • If you talk to people about homelessness, they will readily admit they just don’t want to see it. If go to any cheaper grocery store you definitely are rubbing shoulders with people who use foodbanks. Food insecurity doesn’t go away just because you have a roof over your head.

    The rub is a foodbank in a grocery store will attract the more visible “unreliable access to showers” type of user, which would be unacceptable.



  • Mostly just as a wrapper for Docker. The main issue I’ve run into is Docker’s union file system functionality doesn’t work when backed by ZFS, so disk usage can balloon out of control. I wouldn’t use this in production but don’t tell me how to live my life mom.

    Beyond various Docker stacks I also have a Certbot container that uses Snap (sigh), and Hashicorp Vault container which runs as a vanilla SystemD service. I run Wireguard as part of my OPNSense VM. That’s something I would run in a VM since it’s exposed to the internet. I have an older MinIO and Concourse CI Docker Compose config that I’d love to run in LXC but I suspect that isn’t realistic.

    Note on Vault, I haven’t been able to get mlock to work (used to prevent sensitive memory from being swapped). By all accounts it should just work in LXC, but since it isn’t and there’s no swap on the host I just turned it off. I may migrate Vault to a VM at some point.

    I’m personally just interested in lightweight environments with good enough isolation and don’t break all the time over nothing. Docker mostly accomplishes that for me. LXC + Docker also mostly accomplishes that.

    (My heart yearns for FreeBSD Jails but with decent tooling)


  • I originally excited by Podman, but ultimately migrated away from it. Friendship ended with Ubuntu and Docker -> CentOS and Podman -> Proxmox + Debian LXC (which has its own irritations but anyway). Off the top of my head:

    • Can’t attach a containers to multiple networks. Most of my Docker Compose stacks have an Nginx reverse proxy and a network for each service.
    • But you can use pods. However since they share the same network interface if you have multiple legacy services that both insist on, say, port 80 they can’t be in the same pod. They also don’t isolate services, nor can you assert a specific pod is the one listening on a forwarded port.
    • Pods also have DNS issues with Nginx. It kept crashing since it couldn’t resolve the hostnames of the other containers in the pod, even if they were already running. If you launch a shell inside an Nginx container the other container hostnames resolve fine. I suspect the problem is the container is launched before its behind-the-scenes DNS infrastructure is ready.
    • Podman lets you use secrets on normal containers (yay) but if the secret changes you have to recreate the container. Amazing synergy with rotating TLS certificates.
    • Endless issues with SELinux and bind mounts. My Nginx container kept crashing because SELinux didn’t like the TLS certificate bind mount. This is where I reflected on the endless parade of random issues that I had no interest in solving and finally threw in the towel.

    I brought all this up in another community and was told the problem was [paraphrased] “people keep trying to use Podman like they use Docker” - whatever that means. I do like a number of design choices in it, like including the command used to create containers in the metadata, and how it’s easy to integrate into SystemD for things like scheduled updates.

    Cockpit is pretty slick though, need to install it on my bare metal Debian host.
