Yes.

Ann reason you choose authenik? There are a nmber of options and I’m not sure why to choose one over the other.

If you need to learn C, at least use the first edition of the book - the one without the ANSI additions is much smaller.

I’'ve actually never read the second/and edition so I can’t say if it is good or not. I can tell you that the first edition still has a proud space on my bookshielf though the acid paper is starting to take a toll and I suspect it won’t be long and I’ll be needing a reprint.

Pi’s built in audio is terrible. Even if it works you will want a better audio interface. The PI only has digital inputs (I think there is a mic input), so you need something to get audio in. If you can get the digital audio that is best, but often that is behind encryption and so you end up with analog inputs. (I’m not sure what the options here are, worth looking deeper).

Once you have the audio in, there are a number of Jack (which port audio supports) to network low latency products that will work. Configuration will be hard but that is something you only do once. (configuration is hard because almost everyone who uses this wants a different complex setup and so there is no way to make it easy in a way that would help anyone else)

I was thinking about restoring the backup in a temporary location and running diff on random files to check the files match the source, but I don’t know if this is redundant now.

That isn’t as useful as you would think. If your computer fails there are high odds you will restore to a fresh install of a newer OS and newer software/services versions. Which means that you really want/need to also test data/config migration.

OTOH, if you have backups odds are the data is there even if you never tested them. Testing you can restore is mostly about do you have everything backed up. Your backups can pass all the validation but if you accidentally configured them to only backup /tmp (or something else worthless) you may as well not have backups. Thus you should test that you can do a full restore just to make sure that the data you want is all there. I generally trust that backup software can restore all the data you pointed it at without problems even if you didn’t test them - but I don’t trust that you (or I) configured them to backup the right things.

most of the work is getting media. I spend many hours ripping cds, getting track titles right (popular music this is automatic but I have a lot of obscure cds where this can’t be done). there are ways to download music, but again you will spend time doing that.

movies are even worse in part because there often isn’t a legal way to do things and so even if you have the rare legal movie things are tricky.

Back in the 70’s my dad worked for controll data - I think when Cray still worked for them. One day uniforned military came to the lab he was in with a failed haredrived handcuffed to them (i’m guessing this would have been a 14 inch drive?). They watched while the lab opened the drive to find physically warped platters, then used rags to wipe the oxide off, took the rags tothe parking lot and burned them.

not sure how practical that is for you but it was once the standard to be sure.

Spring break so nothing this weekend. I need to figure out backups and then common passwords/logins for my family.

I use magic mirror for that. I tried homeeassistant but I’m alleric to a million PIs and they make installing any other way hard. (Rant about vm versions not supporting extentions)

what is thisyarty thing

I stand most of the time. I have a wobble board which helps - standing in one place isn’t possible. I’ve been interested in a treadmill for a while, but they make it hard to do anything else and sometimes I want to sit or lean back.

I tried home assistant in docker. Easyetoeget working but for some unknown they make it hard to install extentions so I couldn’t get some things working.

i installed openhab instead which works though there are less extentions available.

Email is often impossible. you can run your own server but you won’t be able to send email to many people because gmail and other larre providers will ignore everything from any ip address you can get. you endeup with email for only people on you server and the what is the point.

just a warning there. Some do self host email but it is the most difficult to host. My life is much better now that I pay fastmail to handle my email.

Start small. The hard part isn’t installing a lot of software and getting it running. The hard part is keeping everything updated over time. So install one interesting service, and then figure out how the update process goes before installing another. Hopefully the worst thing that happens is you install services and use them only to have the computer fail in a few years after you depend on them and you can’t figure out how to get the data into the new version. There is also the very real possibility that your service is compromised by an attacker.

I name them after a female important character in whatever novel I’m enjoying when I set the system up. Back when I was single the female was important, now it is just tradition.

Since I like fantasy there are plenty of names available that are both pronounceable and nonsense.

My NAS is behind a firewall and doesn’t normally run the types of things you would compromise. (no web browser). They need to break many things at the same time to compromise it. I’m not saying it would be impossible to compromise my NAS, but is is very unlikely just because of how difficult it is. If I’m target of a state level attack I’m sunk anyway.

though offline backups are always a good idea. However they by definition need several days to restore (if they take less than that they are too easy for an attacker to target)

I put all my data on a NAS with non-writable snapshots so hackers cannot destroy my data.

Just remember any backup is better than nothing. Even if the backup is done wrong (this includes untested!) odds are you can read it and extract at least some data, it just may take a lot of time. Backups that are done right just mean that when (not if!) your computers break you are quickly back up and running.

There are several reasons to backup data only and not the full system. First you may be unable to find a computer exactly/enough like the one that broke, and so the old system backup won’t even run. Second, even if you can find an identical enough system, do you want to, or maybe it is time to upgrade anyway - there are pros and cons of arm (raspberry pi) vs x86 servers (there are other obscure options you might want but those are the main ones), and you may want to switch anyway since you have. Third, odds are some of the services need to be upgraded and so you may as well use this forced computer time to apply the upgrade. Last, you may change how many servers you have, should you split services to different computers, or maybe consolidate the services on the system that died to some other server you already have.

The only advantage of a full system backup is when they work they are the fastest way to get going again.

Go to local “art in the park”, music nights, and other such local events and listen to the band playing. Unless you live in a very rural area there is likely many many bands playing someplace every day around you. When you hear something you life find the band and ask how to get their music. If they sell CDs buy one - buy one even if you only accept the music but don’t like it just to support the idea that CDs are not dead.

I’m not stopping you. However make sure you understand what you want to do and why it isn’t recommended in general. It looks like an interesting project that I hope to read about sometime (hopefully not as a you sunk to the bottom of the ocean)
