The limits of our knowledge of biology. There is no particular reason I shouldn't be able to regrow you from the skin cell you left on the doorknob - the DNA is all there - but nobody has any clue how you would go about doing that. (if we ever get there it will make for some interesting nature vs nurture data). Only time will tell how much we figure out in the future. For today the limits are where they are.
ZFS even if only one server is much better than most people have. If your ZFS replication is to a different building you have done pretty good. However as others have pointed out there are limits. Those servers costs you a couple bucks/month in electric (where I live my electric is 100% wind, but most of you should read CO2). You have to buy both servers, and hard drives will crash regularly.
There are a lot of trade offs, but cold storage backups are often much cheaper in the long run than the backup zfs server. And those cold backups are a lot easier to put into multiple different locations.
It is a pain to figure out how to give everyone the same user id. I only have a couple computers at home. I've never figured out how to make LDAP work (including laptops which might not have network access when I'm on the road). Worse some systems start with userid 1000, some 1001. NFS is a real mess - but I use it because I haven't found anything better for unix.
on life support thay haven't pulled the plug yet but it is coming. They are not updating anything not urgent and so new hardware support is dead as are jails to do useful things. I'm probably moving to xigmanas in the near future.
They had to define planet and that left a hole of large thing smaller than a planet but larger than what they wanted to call an asteroid.
they had other options when they defined planet. I preferred the on that turn our moon into a planet - but they didn't listen to me. (They should not listen to me - I'm not an astronomer)
I know, I like BSD. However because core isn't a supported version of FreeBSD I cannot update the other things I run on my NAS. I'm more worried about an attack on those out of date services than I am about the few issues that have been fixed
At least you get updates. I'm running TruNAS core which isn't updated anymore, and I have some jails doing things so I can't migrate to scale easially.
The good news is this still works despite no updates it does everything it used to. There is almost zero reason to update any working NAS if it is behind a firewall.
The bad news is those jails are doing useful things and because I'm out of date I can't update what is in them. Some of those services have new versions that add new features that I really really want.
I have ordered (should arrive tomorrow) a N100 which I'm going to manually migrate the useful services to one at a time. Once that is doing I'll probably switch to XigmaNAS so I can stick with FreeBSD. (I've always preferred FreeBSD). That will leave my NAS as just file storage for a while, though depending on how I like XigmaNAS I might or might not run services on that.
Odds are strongly against a 2 drive failure at your scale, though it does happen. I set my NAS up about 8 years ago, with 6 drives with raid-6 (well zfs's version) and in that time two drives have failed years apart. When you get two hundreds of drives total in your operation you will see a dual drive failure.
Though you still really should have backups of everything you care about. Even though odds are in your favor someone reading this will lose data in their life on their NAS system.
https://www.modelfkeyboards.com/store/ is what I'm looking a for my next keyboard. I am typing this on a Keychron which I will agree with others is a great keyboard option for somewhat cheap.
For general computer stuff B&H. Though if I knew of a local store near me I'd be sure to support them.
I look for borderline answers that I can get wrong just to mess with any training they do.
Though it is suspected that they don't care what you click so much as you click like a human - random times between clicks consistent with moving body parts.
Only for the moment. Spammers have already found us, but so far in small numbers. All the other bad parts of social media are already here too, just so far not in large amounts and so you can find useful content. But those who gain from the garbage are coming and decentralization doesn't help.
If you must be on those platforms (because face it, that is where grandma is) don't doom scroll. I block all from the creator of shared memes on facebook - then when I block two I use that as a sign I'm done for the day. You should follow similar rules - make it clear that you want social media for social purposes and the memes, information (which is likely false or exaggerated), and everything else is not welcome to you. Alone you and I are nothing, but together we start to become a statistics that they will notice. Thus my plea that you follow similar rules as me in blocking the non-social parts and not doom scrolling - if there are enough of us they will be forced to make their platform more useful to keep us for one more ad.
So why are we talking - nothing gives me any indication you are in the same community as me (odds are strongly against it), so nothing is being organized. The world needs more ways to organize communities not large groups who don't have a small communities in common to do something about.
Just like kde 4.0 and wayland were not marketed to consumers and yet consumers used them anyway and then decided latter releases marketed to consumers must also be bad.
What rights do they have. There is a big difference between they have (or plan to have) a tunnel under your house if the vein of whatever they are mining happens to go that way, and they have rights to knock down your house. Different states have different rules.
Oil is a liquid so if they have a well on your neighbor's land they are taking "your" oil so it makes sense to make them buy out the entire neighborhood - but they are don't need to access your surface, the pump elsewhere is enough. Similar for underground mines, they follow the vein of mineral wherever, and don't care what you do on the surface.
However there are other cases where their pit mine gets bigger and they need to take your land and your can do nothing about it since they have those rights they give you notice and a check (they probably have to buy your house, but maybe not!) and you have to leave in a few months.
In between they can put a well or ventilation shaft in your backyard, but other than having to look at it forever, and the time when they build it there isn't much loss of your yard (some loss, but not much).
The good news, in places where this is done all the time the courts and law have worked out all the details. The contracts tend to be 1 page that just refers to the hundreds of pages of legal documents saying how things are done. (by contrast if you lease land for a wind turbine it will be hundreds of pages - the legal details are not known so they have to cover all the details) You can go to a local cafe and ask a stranger and probably get reasonably good advice since everyone will know what really happens based on what happened to someone else. Or half an hour with a lawyer and get real information.
The bad news, different states have different rules. Sometimes cities or counties also have rules. As such there is no way anyone can say anything without knowing exactly where you live.
Swiss banhs used to do this, but not anymore. Cayman islands is said to do this but I don't know details. Otherwise russia or north korea might help. nothing where you should trust your money to though.
note that even though you might find a place to do this it is still illegal and it is generally not hard to follow money trails so you ard likely to be caught.
