I discovered Open Food Facts very recently. I was supersurprised because the mobile app is very neat, and I didn't expect there would be so many products (edit: in Spain). I've sent two contributions so far.

Also, you can download their database. If I had some time, I'd try to run some queries on it. (I'm on a low sodium diet and sometimes you find the most unexpected products with little salt, but it's time consuming.)

edit: also, I forgot, the app is on F-Droid, another nice touch.

You need two drives for the OS, four for data. Hetzner boxes are cheap with 2 drives, cost multiplies if you add any other.

I use LDAP auth, but no SSO or external mounts. Actually, I tested external mounts, but they gave me bad vibes, although they are interesting.

The other thing, I just run a preview generator application, no other plugins.

I was looking at the Proxmox graphs. Now, looking at iostat, r/s measured over 10s hovers between 0 and 0.20, with no visible effect of spamming reload on a Nextcloud URL. If you want me to run any other measurement command, happy to.

I like to live on the edge of time and therefore have the feeling that debian based distros (although being very stable) are too “old” for my liking.

Nowadays, with Flatpaks, so many software providing binaries, etc. this does not matter so much. If you want, you can even use something like Distrobox to have containers for tools using whatever bleeding edge distro you want, but still have a solid stable underpinning.

Debian also has more stuff than you would expect in backports. The main sticking point is yes, you'll be stuck in Debian 12's KDE until 13 comes out. But that might be sufficient for you?

(You could also use Debian Testing, which is basically a rolling release. But I'd consider stable first.)

Eh, my Nextcloud LXC container idles at less than 4.5% CPU usage ("max over the week" from Proxmox). I use PostgreSQL as the backend on a separate LXC container that has some peaks of 9% CPU usage, but is normally at 5% too.

I only have two users, though. But both containers have barely IO activity.

Web-accessible Emacs? What are you using?

I keep everything documented, along with my infrastructure as code stuff. Briefly:

• Nextcloud
• Vaultwarden
• Miniflux
• My blog
• Takahe (a multi-domain) ActivityPub server
• My health tracker CRUD data entry
• https://alexpdp7.github.io/selfhostwatch/
• Grafana (for health stats and monitoring data from Nagios)
• Nagios
• FreeIPA/Ipsilon (SSO)

edit: plus a few things that do not have a web UI.

I was going to mention ZFS, but I suspect Raspberries are too weak for ZFS?

If you can use ZFS in both sides, send/receive is the bomb. (I use it for my backups.) However, I'm not sure how well encryption would work for your purpose. IIRC, last time I looked at it, if you wanted an encrypted replica, the source dataset should be encrypted, which did not make me happy.

I'd love to work on making NASes "great" for non-technical people. I feel it's key. Sending encrypted backups through peers is one of my personal obsessions. It should be possible for people to buy two NAS, then set up encrypted backups over the Internet with a simple procedure. I wish TrueNAS Scale enabled that- right now it's the closest thing that exists, I think.

The next TrueNAS Scale can do LXC containers using Incus. It's similar to a VM, but more lightweight. You can create a container for any Linux distro and install Borg on that. With previous versions, I googled and found some instructions to run Borg in a container with SSH, or you could use a VM.

Borg also supports dummy SSH targets, that TrueNAS can provide. Apparently, it's lower performance-

Why the choice of TrueNAS Scale? For just a Borg target, you could run any Linux distribution.

YunoHost is very nice to run on a VPS (or a box at home, or anything). It has good email hosting support, and I feel people without systems administration experience could get it running and host a couple of apps for a group without too much trouble.

TrueNAS Scale has awesome NAS capabilities. ZFS is the bomb. Plus, they are integrating Incus, which I'm a huge fan of. I think it hits a sweet spot for people with systems administration experience. Just install it and you get great NAS capabilities, the option of running a K8S instance, LXC/VM capabilities, and some "app catalog" (I test drove that briefly and it looked decent, but I think less hands-free than Yunohost.). My pet peeve (and I understand why they do this) is that you need separate drives for the OS and for data, so if you want redundancy you need 4 drives- which is likely fine for home use, but I'd like to run TrueNAS Scale on a Hetzner dedicated server, and that increases costs a lot.

If your primary desire is to run a few apps and you want to minimize your learning/effort, I'd check out YunoHost. If you want to do more, but also invest more time, TrueNAS Scale is awesome.

I did some testing with it, because I believe more people should be able to self-host.

I like how it is implemented. It has good support for email. Many apps support SSO.

The critical part to me is how up-to-date applications are. I started a small project to automate version tracking, check out:

https://alexpdp7.github.io/selfhostwatch/app/nextcloud.html

; so for example, the YunoHost Nextcloud app does not lag much behind upstream. My intention with this is to let people see that they have been updating Nextcloud dilligently for two years; they might pull the plug tomorrow, but it's a good track record.

(I'd like to add scrapers to other projects similar to YunoHost. My ultimate goal would be to be able to choose a list of apps you'd like to self-host, and see which projects like YunoHost carry the applications you want, and compare how they track updates.)
