Learning how to use your pi to run a reverse proxy to a self hosted blogging site would give you plenty of hands on starter experience. Run docker and portainer and mess with docker config files from a webgui to see what work and what doesn't.
As a self taught self-hosting enthusiast i wouldn't recommend ansible to a beginner. I know that sounds backwards as absible makes everything easy and does all the work for you but that's also part of the problem. It would be like jumping behind the wheel of a self driving car without knowing how to drive at all. When (not if) something goes wrong it could go wrong hard and you'd lose the whole instance.
It's better to start with some other self hosted projects that interest you to get a feel for the process and software like docker then work your way up to bigger things like lemmy. I consider myself fairly versed in the process and lemmy still gave me some issues to set up and my pixelfed instance still won't federate despite my best efforts. I'm pretty sure i know the issue, i just need to get around to fixing it.
Last thought, the raspberry pi is a pretty impressive little pc for it's size and price point but you might find yourself quickly burning through resources depending on the number of active users you have and how heavily you use it.
The argument isn't about control, it's about agreed upon terms in a contract of employment. If she agreed to conduct herself a specific way when she signed her contract and then did the opposite this is a matter of breach of contract. Should schools hold their employees to such standards is a different conversation than should an employer hold an employee accountable when they break the terms they agreed to.
To frame the situation in another light, despite being a room full of adults who can consent it's generally regarded as a terminatable offense if a college professor has a relationship with a student, even when both parties are consenting. With that in mind should it be acceptable for a teacher of under aged students to generate content of a sexual nature with the intent of mass distribution? Students in her school/class will inevitably gain access to that content and now you have a situation where a highschool teacher has exposed themself to children. With that in mind this seems like the kind of thing you'd consider an improper act of conduct.
I'm not sure why you're getting down voted when you're right. Most schools put a clause in their contract involving public conduct that can go as far as suggesting what you can't wear during off hours. Teachers jump through a lot of hoops for employment which is why their low salary is always a talking point.
Underrated explanation, you held it finally click for me. I consider myself a fairly educated person but just couldn't wrap my head around what made it so special. Correct me if i'm wrong but my understanding is the server uses the public key to encrypt a challenge code that can only be decrypted by your private key. You get an on device prompt to approve the process and the rest is done under the hood.
To go further on this, is the public/private key a mathematical relationship? What ties the two together to make them useful as a pair?
One is a hopeful future the other is a mythical past. I lean towards trek because i want to believe a version of that future is possible.
AudioBookShelf is a beautiful podcast option. OP would have to fully migrate into it but once done it'll let you listen to an episode on pc, pause, then resume from the same spot on mobile. It'll auto grab episode as they come out and store them on your system for streaming or local access. The android app is pretty good and i know webapp works well on ios
That goes hand in hand with a level of trust with some companies/people and everyone has different threat tolerances. It also highlights the mindset that you have no idea what the person on the other end of the message is doing with it. End to end encryption helps keep in line eavesdropping down but if the recipient of the message has a compromised device or are screenshoting everything and posting it on facebook it's out of your control.
As someone else said, selfhosting is the only real way to overcome this problem. When it's all on your hardware it matters a lot less if the messaged at are decrypted server side or not. Everyone has a different threat level and at some point you have to put trust in some companies but if beeper makes you uncomfortable then buy a cheap second hand mini pc and learn to self host the service.
I'm never a fan of virtualizing network related items for the sake of redundancy, if your server goes down the rest of your network can keep doing it's thing. That being said, with the hardware you have on your hands i don't see any solid atonemen argument for bringing in more hardware.
Proxmox is a great base for you to really ramp things up and i'd recommend looking into pfsense as a routing/firewall solution. There's a bunch of great youtube videos that can talk you through setting it up and using it as your vpn point, adblocking, reverse proxy, and so much more.
