Most of those free dns settups use subdomains already. Unless you cant, for a temporary domain name, I recommend just creating an account at a mainstream/reputable dns provider and buying whatever is on sale for a dollar or two per year. Dont plan on renewing because those ones shoot up.

Hopefully the .self tld becomes a thing because it is supposed to be free: https://hccf.onmy.cloud/2026/06/21/reclaiming-our-digital-selves-hccfs-vision-for-a-human-centered-top-level-domain/

Its about balancing your priorities for availability with recouverability. A business loses a lot more money than I do over a couple days downtime.

Mirrored drives are not backup drives, and vice versa. Though ZFS can definitely start to blur the distinction with automated snapshots and especially offsite mirrors.

Ram is expensive… so all my 24x7 things are containers (docker compose on Alpine Linux) or FreeBSD jails.

Restic’s dedupe is very good. I used to take uncompressed tars of whole systems and it would add only megabytes to the storage repo each time. Almost everything got deduped despite being in various tar files and very fast.

Do you use plain webdav for all your files? Mounted on your computer or via libreoffice somehow?

Thanks. I have spent the day reading about M-disc and optical formats. Lemmy is great for starting rabbit holes! I think I may swap a blu-ray burner into one of my machines and I am actually thinking dual layer blu ray is a decent trade-off: simmiliar chemistry to m-disc (unlike the clear superiority of m disc over DVDs -which I was literally burned on the other week with some yellowed DVDs), and yet still cheap, reasonable amount of disc shuffling, and in the future, nearly any blu ray drive will work with the 50gb discs (unlike 100gb disks). Still might grab a blu ray m disc burner if I see a good deal but they seem rarer than a hens tooth. Lol.

I have less than a TB of truly irreplacable stuff, so 20 discs isnt bad to suffle, and aiming for maybe 20 years of electrically safe cold storage* zero maintenance off-site seems pretty reasonable for a $50 drive and about that in discs.

*This is overkill anyway - already have zfs snapshots going to an external drive in another room and restic backups to b2. But the threat model is some combination of losing b2 (credit card fail or my own incompetence) plus housefire/robbery/electrical surge taking out everything. Also, if I get hit by a bus and my CC is cancelled, a box of transparrently readable discs are significantly safer bet for my survivors than my note about how to get the data off the NAS/backup drive. They could leave it 5+ years and come back to it no problem.

I have wondered about how to manage a 100 spool of DVDs as long term cold storage of the most important data. Would need some way of splitting the data up automatically and building a straightforward burning workflow, with redundancy incase a disk is destroyed, and a way to find a given file.

Seems like a lot of work for 400-ish Gb, but 1. Its very cheap, 2. Archival disks could last a lot longer in cold storage than anything else affordable, and 3. Anyone could recover it in the future because DVD drives have been manufactured by the billion and are still being put in some office PCs. 100gb blurays are also an option but that means sourcing a burner and at least a few drives capable of reading them to store alongside.

Edit: at first blush, plain files to make recouvery easier plus par2 files scattered across enough disks to be able to lose a whole disk or have many damaged disks seems like the right format. Some sort of index would need to be built and left on every/most disks or maybe printed on paper. Its mainly the workflow to do it that would be a PITA. Then maybe vacuum seal the spool with some moisture and oxygen absorbers and put in a lightproof container. Good for decades later? Maybe.

I just restored from some 20 year old dvds and they had visible yellowing at the edges and lost data at the end. A few videos were unrecouverable, not many.

Indeed, I log in pretty rarely.

Their admin interface is slow and awkward, but otherwise happy. Their deals are always changing and I currently have good specs for the money. EU company and my machine is in Montreal, so I was happy with non-American hosting and green electricity.

There are constant scanners on any site and scrapers on websites, but it is far less of a problem than you would imagine unless you have a big wiki or software forge with hundreds of nested commit history pages for them to spider into.

I also run private servers on hidden subdomains (with wildcard certs and DNS entries), so the low effort scanners never bother them.

DDOS attacks take money, so they aren’t typically going to go after some random homelabber. If it did happen, I would either just shut it off for a while or change the VPs IP. Ovh also has some of its own ddos protection.

Keep in mind that you wouldn’t route local traffic through it, so everything watched at home would be direct and not count.

I have a $5/mo VPS with OVH and they allow unlimited bandwidth within reason. Unless you have multiple households streaming from your server all the time, likely totally fine. If you do end up with one relative streaming 24x7, then I would look at installing the tailscale app on their TV and configuring things to connect that one user direct to your home server.

A VPS takes some learning, but IMHO, it is the “correct” answer and worthile learning.

If all you need is a static IP and a little traffic, there are free-tier or a couple bucks a month vps options. Use SSH to proxy a single port to connect to their service.

Really a long time coming pain point is comfortably sharing between family. I think the new workflows will be the way eventually. I plan on using it to auto add pictures with the recognised faces of family members to a “Family Photos” album as they are uploaded, and allow everything else to stay unshared by default for each user.

Your idea works in theory, but in practice, using a ZigBee plug as a power sensor -even if you managed to program a way of detecting its online/offline status, will probably have too many issues.

The protocol is designed for low power and so has to be robust to temporary connectivity issues from interference. You would either have too much latency between the switch and the light turning on/off, or you would have phantom switching of the light whenever some other device in your house desides to do its thing.

It is a genuinely neat idea you had though.

You have the right attitude and I hope you are able to successfully shop around. Some institutions are paying below living wages to overworked and precariously employed instructors. Of course they phone it in. Those places are not worth your money and just trying to cash in on the “diploma” ==“job ticket” mentality.

Find a place that actually gives a shit about education and you should find professors interested in actual education that will see your attitude as refreshing.

40 years of telling kids a degree is a job ticket rather than explaining the value of a liberal arts education.

Every time I see k12 education discussion focused on “preparing kids for the job market” I cringe. Its the cart before the horse and just as agile.

Works fine… Most of the time. As long as the file gets saved at an instant in time (e.g. zfs snapshot), postgres sees it like a power failure and restores. You want to have several recent backups if you do this because it will occasionally fail.

Yeah, I bind mount the config inside a config directory just below the compose file, and the state (databases, files, etc) to a seperate storage location that makes sense. The compose and config gets added to git and pushed to a forge, while the storage directories are backed up like normal (in my case, zfs snapshots pushed to another computer and then restic backs up those cold files to b2. The volumes are ephemeral.
