...it... it was a joke. but OK thanks for letting us know.

At the top of the Lemmy UI underneath your title is a row of option icons; the icon to the left of the last icon with the three vertical dots - looks like maybe the Copy icon, sorta - is the Crosspost option. Click it and follow your nose, the new community dropdown is at the bottom of that next screen.
I would probably add rubber/etc feet on the cage to keep it from vibrating around as they spin, and maybe a handle for carrying! It's a mobile laptop after all... :) What if someone tries to snatch-and-grab a HDD while you're getting a coffee, do we have an alarm system? Lo-jack?
I feel attacked ;)
I have not tried/used it (yet?), but the kids are building Radicle for this very purpose. It gets a fair amount of techie coverage (blogs, comments, etc.) but sits in unique space compared to, say, Forgejo (classic self-hosted git).
The above said, it wasn't hard to find a project using XDG and a JSON mapping file (basically your idea fleshed out in python) to get where you want to go if XDG is enough: https://github.com/JonTheNiceGuy/usbrowser
You're not going to like this answer - there's a bunch of different ways depending on the app(s) and the desktop environment. The Arch wiki goes over it in detail: https://wiki.archlinux.org/title/Default_applications
I would guess that focusing on the XDG spec and covering Gnome, KDE and Xfce (Xfce can be replaced with anything else like Cinnamon that comes with Mint, "non Gnome or KDE") is the best plan of attack for what matters to 80%+ of the population.
mote absolutely understands the law, addie is creating and moving goalposts to support their tirade. The person I was responding to made a ludicrous statement, to which I refuted with observable evidence (laws).
It is obvious to any reasonable person I was referring to and talking about the common folding pocket knife, not kitchen knives or other fixed bladed implements. I may not have written "folding" and it was implied, that could have been better. Your choice to move to some other mental place to complain is your choice, not mine.
But let's get to the meat of your off-kilter tirade - what I have stated and am referring to is an anomaly in the world of knives; the locking mechanisms (there are several designs) on a 3" folding pocket knife is there for user safety. If you have owned and operated pocket knives under force, they can and will twist in your hand. And without a locking mechanism, they can and will snap shut on your fingers and slice you up. I know this personally. It fucking hurts.
I am very aware the UK has banned such an object because they believe it will curtail knife violence. I feel this is trading an actual proven safety feature for "feel good" nanny law that probably don't matter to someone intent on committing knife violence. It only harms the honest user of the pocket knife who wishes to not mutilate their fingers.
A three-inch blade is allowed provided it doesn’t lock in place; as long as it just folds away (like a swiss army knife) then it’s fine. Three-inch butterfly knife will get you in a lot of bother, though.
You go from from a nice pocket knife to a fucking butterfly knife, like holy shit there's an entire world of cutlery between those two and you jump to some crazy extreme with butterfly knives. Those knives are actually curtailed by laws of their own (switchblades, butterfly knives and other "assisted open" cutlery is vastly illegal in many places in the world) as they tend to overlap with gang violence laws ("public nuisance" in the legal chapters). This is not the same mechanisms or designs as safety locks on a folding pocket knife used by regular people doing regular things.
The UK outlaws the safety knife (it's designed for cutting seat belts, smashing a car window and other save your life things) I keep in my vehicle next to a flashlight, because it's longer than 3" and has a locking mechanism. You are not using this thing for knife violence. (search "spyderco rescue knife") But, this tool is illegal in the UK because of it's features.
So yeah, I understand the law. But I also understand knives and cutlery as I'm interested in the steels used, so just happen to learn other things along the way. And to be fair, other countries have just as stupid laws about other things, including my own. I'm specifically discussing this one law and it's irrelevant it's the UK for purposes of discussion of the law itself banning a safety feature.
In the UK, a knife with a blade over 3" and/or any safety locking mechanism is illegal. This same extremely common knife is legal to carry (typical utility pocket knife) in a majority of other parts of the world.
So close! you have to do cat < foo.txt :-) (/s)

Put HE (dns.he.net) in your back pocket - they run a free DNS service which includes slave (do we still call it that?) service so that you can add their resolver as an ultimate failover / failback if your self hosted DNS takes a dive for whatever reason things break in our world.
Generally, hosting your own DNS "should" mean having a primary and secondary on separate AS networks, or at least different provider routes or locations. But if you're doing all this from home, where is the second location for DR purposes... exactly? I sure don't have one, power goes out here everything goes dark - in the old days everyone used to do this (share out tertiary DNS to each other) but it's become a thing of the past in today's world. HE can help fill that gap.
To your point - I use Gcore DNS and Bunny DNS for my stuff, as I mainly use online VPSes and don't run racks of hardware at the house. The only things I physically selfhost at home are a pair of old laptops acting as storage servers which backup all my bytes and bits from online to some SSDs.
