Ah, sucks :(
I'm looking forward to see where Incus OS goes, or TrueNAS Scale. Honestly, I was very tempted to automate a procedure to take a Proxmox ZFS install and replace the Proxmox bits with Incus bits :) Incus + ZFS as an appliance would be nice. I kinda don't want to think about the underlying OS.
It's on backports :D
(I'm actually running it from the Zabbly repos.)
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 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.)
I see some CPU and memory usage on my setup... but I don't even see any IO!
Literally, the IO chart for "week (maximum)" on Proxmox for my Nextcloud LXC container is 0, except for two bursts, of 3 hours of less each. (Maybe package updates?)
The PostgreSQL LXC container has some more activity (but not much), but that's backing Nextcloud and four other applications (one being Miniflux, which has much more data churn).
Huh, what?
I see in your link that that image has support for KasmVNC, which is great and you could use to make Emacs work...
But the whole point of VS Code is that it can run in a browser and not use a remote desktop solution- which is always going to be a worse experience than a locally-rendered UI.
I kinda expect someone to package Emacs with a JS terminal, or with a browser-friendly frontend, but I'm always very surprised that this does not exist. (It would be pretty cool to have a Git forge that can spawn an Emacs with my configuration on a browser to edit a repository.)
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:
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.
I dunno, I still have a soft spot for Proxmox. I want ZFS, so it's about the only game in town with support.
(TrueNAS Scale looks good, but it would increase too much my Hetzner costs, because of their requirement of having a dedicated root pool. And I don't want an LTS distro that supports root-on-ZFS "oficially". That narrows the field quite a bit.)
(For work and for my workstations, I'm very pleased with Incus on top of Debian... but that's because I don't need ZFS on those.)
