    1. Some episodes and movies show ships that are essentially flying holodecks. Energy doesn’t seems to be a problem.
    2. That’s the point: You don’t need real-world things. The reason the holodeck is so large is to accommodate dozens of people at the same time.
    3. Some kind of multiplayer function across several holodecks should be possible.
    4. You either have a holodoctor for everyone who needs one or the few medical practitioners see a holo of their patient on which they operate. The holoroom the patient is in then replicates what the doctors are doing.

    Do I use BTRFS or ZFS? I tend to use ZFS because of its advantages when making backups. What would you do?

    Usually VMs are usually I/O starved therefore I would try to go as lightweight as possible and chose Ext4 or XFS (depending on what the VM is used for). The VMs can be backed up whole by Proxmox. You have more than enough space to do that and it’s considerably easier to set up. And honestly how big could the containers and VMs be? I guess the containers are 50-200 MB and a VM a few GBs. That’s almost nothing.

    Do I use QEMU/KVM virtual machines or LXC/LXD cointainers? Performance wise QEMU emulating the host architecture should be the way to go, right?

    LXC containers are way more lightweight than VMs. I depends on what you want to do. Docker and a file server work better in a VM so far but Pi-hole and Jellyfin run perfectly in a container.

    I shy away from running all services as Docker on the same machine for backup/restore purposes and rather have VMs per service. Is there anything wrong with this approach?

    I would go for LXC first. If that isn’t possible or too cumbersome I would try docker (in a VM) next and one-VM-per-service last as they need the most resources.

    I’d love to keep NextcloudPi (because it’d make it easy to migrate settings and files) and there’s an LXD container for it. Would you recommend doing a switch to Nextcloud AIO instead?

    Sorry, no idea.

    I’ve equipped the Deskmeet X300 with a WiFi card and antennas. AFAIU trying to use WLAN instead of LAN will create some trouble. Has anyone running Proxmox on a machine with WLAN insteal of LAN access successfully?

    I would always try to connect it to LAN.

    I’m aware that Proxmox comes with a firewall, but I don’t feel very confortable using a software firewall running on the same machine that hosts the virtual machines. Is this just me being paranoid or would you recommend putting a hardware firewall between the internet access and the Proxmox server?

    No idea. I wouldn’t mind a firewall container. If something breaks through you are fucked one way or the other. The firewall in your router isn’t much different than any other.
    You should always go for Wireguard or another VPN to access your network from the outside.

    What else should I think of, but haven’t talked about/asked yet?

    Helper scripts for beginners: https://community-scripts.github.io/ProxmoxVE/
    Just give them a look.

    And it seems you are ignoring Proxmox’ LXC. They are one of main reasons to pick that software.

    Edit: As an additional note: I ran about 6 or 7 VMs on a mini PC (Intel N100) with 16 GB RAM. RAM was almost used up and the cpu was at ~15 %.
    I then switched mostly to LXC and only one VM. The cpu was now at ~1% and RAM usage went down to 3 GB while still providing the same services as before.
    The power of containers, baby! :D


  • As for why all rooms aren’t holodecks/suites in the 24th century, probably due to power consumption.

    It’s been a while and I might not remember correctly. Wasn’t there an episode in Voy? with holographic lifeforms that rebelled against their creators and lived inside a flying holodeck ship? And there was that Insurrection movie in which a whole village was teleported into a giant holodeck ship.

    It seems possible.





  • WHY DO YOU NEED MY DATA TO MAKE FIREFOX WORK???

    They don’t care about your actual data, they care about how Firefox is used. That’s an incredible important piece of information every developer needs to know.
    How else do you get to know, what’s working right and what doesn’t? How do you plan development for the next years if you don’t know what to develop?

    This is about throwing millions of $ at the right thing. If you miss you are fucked.
