    I don’t want to speculate as to the fate of the baby, the corrugated sheet metal had to be moved and it was only a few minutes after I had removed it that we heard the squeaking. Nature is gonna nature, either the squirrel will survive, or a predator will get an easy meal. The thing is, within the family, we will probably ask “is that the squirrel all grown up?” every time we see a squirrel up there for the next few years. I think that’s the best outcome we can hope for.

    My setup is a bit extreme, but here are my guardrails:

    1. All users have the same UID’s on every system. I’m 1000, wife is 1001, son is 1002, daughter is 1003. All these exist on all systems. Our primary group is “family” (gid 10000). Our files are all owned by user:family. This matters because we let them have access to the share of things like home movies and pictures, and I have a TrueNAS with an NFS mount that their user folders rsync to nightly for backup. If you wanna get crazy, you can put in a whole LDAP/freeIPA setup, but that’s a lot (and I did all that as a learning experience).
    2. They don’t have the account passwords. I have their password, and if they want to use it, the wife or I have to type the password. When we want them off, superkey+L to lock the computer, and if they reboot it comes to a login screen.
    3. If you really go this route, and go the whole LDAP thing, you can also tie that into apps like Jellyfin. I have a huge library of movies and shows, but there’s a folder called “KidMedia” and I literally manually symlink things to that folder if I want them to have access. I set up the phones/tablet with their own jellyfin accounts, and when they log in they only see their media. I also NFS mount that share, so for the same reason, they can watch stuff on VLC from the computer with access control. We also do that with nextcloud, so we can use nextcloud talk to chat internally. The tablets/phones have built in android controls, so the idea is once they’re on their device, they’re free within the ecosystem I set up and they don’t enter credentials other than device unlock.

    I built my kids potato computers from the time they were 3-5, which was during covid. They need computer skills nowadays, and it put them at an advantage for covid school. We got them on java Minecraft which was huge for reading, typing, and some basic math skills (they figured out multiplication for crafting things like doors). I made a chart which had icons of things they want, with the word next to it, so they could search and type in creative.

    We used Ubuntu Mate. It’s simple, stable, and familiar. They do NOT have sudo on these boxes. As we’ve advanced, they now have firefox (behind a pihole which upstreams to opendns’ family protect), gimp (with a wacom tablet!), inkscape, calculators, tenacity, libre office, and they’re starting to get into some cad to make things to 3d print. You have to come to terms with doing a LOT of patient hand holding, but it has paid off dividends.





  • Yes, we are a medical/dental/pharmacy university and because of some of the specific data needs of our org we have a large on-prem ecosystem. We are currently a VMWare shop, but Broadcom’s business strategies have made us look for alternatives. I’ve used Proxmox in the homelab for years and have been feeling as its gotten more and more polished it’s ready to be considered for production work. Currently we have a lab environment of previous gen hardware which I want to use as a test-bed for possible production platform moves.

    Proxmox isn’t VMware yet, but it’s close. The HA doesn’t work the same, I’ve struggled with something akin to DRS. If you use on-host storage, you have to constantly do replication work to keep them synced and even then a failover is essentially a storage rollback to the last sync. If you use iscsi storage, you have to be very careful. Snapshotting is only functional when backed by a few of the storage types, and we use ZFS. ZFS over isci is somewhat brittle, but we have a TrueNAS device which supports it here. We use Veeam as our enterprise backup solution, and I have no idea how these will work together. Veeam talks directly to our Nimble storage, does storage-based snapshots, and replicates them to our other site. Veeam theoretically does talk to TrueNAS, but without supporting Proxmox I don’t know what the backup/recovery flow would look like. Veeam is looking into this: https://community.veeam.com/discussion-boards-66/veeam-researching-support-for-vmware-alternative-proxmox-as-backup-buyers-fret-about-broadcom-6530 We tried to use TrueNas ZFS snapshots for just general VM semi-backup, but unless you want to rollback your whole dataset, it doesn’t work well. You have to make separate snapshot tasks for the specific zvol/dataset, otherwise you’re rolling your whole dataset back. Also, I tried mounting a snapshot, hoping to then share it as an iSCSI extent and remount it to a VM and pull out a specific file…this didn’t work at all, I can’t get the UI to show the promoted clone so I can try to present it to the host.

    When coming back from a power-off, if your Proxmox hosts are in a cluster, there’s no cluster-aware startup order (HA disables the entire startup delay system). That’s not great, our apps have SQL dependencies which need to be started first.

    That’s the issues, and it sounds negative, but ultimately for a zero-cost hypervisor that’s under active development those issues need to be viewed through the lens of the overwhelming achievement that the project is and continues to be.




  • Lego parts are incredibly precise, and the manufacturing tolerances have been consistent for decades. It’s nearly impossible to replicate that precision on any modern printers.

    That being said, different parts are more tolerant of wiggle room. Grabbing a stud is hard, grabbing a 2x4 is not. If you were going to print a minifig head, trying to replicate the neck barrel is gonna be tough, but making a larger hole with 2-3 ridges which taper to grip might be easier. If you plan what you’re doing and are realistic about what you can print, it’s definitely not out of the question.

    Lego is ABS if I’m correct.
