Celsius is defined at the arbitrary standard pressure, different pressure values change how water acts (this is very noticeable at 100C - boiling). Kelvin steps are defined from Celsius. Even the speed of light which is constant is still defined in terms of an arbitrary time unit.

Go slow. measure 4 times. most rooms don’t need a jack so put APs where it is easy to ge wires and that will feed the other rooms.

Installed grocy on a server and magic mirror on a pi. Now we can track all the daily tasks of life which makes my wife happy

There is a reason I put arch on my latest computer. I will give it a few months to be sure but I’m thinking of swicthing. details matter so when printing doesn’t ‘just work’ in one program with a print dialog I know snap is not ready for ubuntus target.

Static, hand coded html. You can be as pretty as you want to be. A good learning exercise and since it is all static it will be fast and won’t have more security issues.

That means you haven’t make them large enough yet.

Good luck getting people to care, but it is in the end your best counter.

Long term boycottes are the best thing - IF you can get large numbers to follow. Large enough that management schools are forced to teach about how ever real reform won’t be enough to save you from bad actions.

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.

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

only the most basic security. It is out of date according to the pkg system and so jails cannot be updated-

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.
