Professional audits happen for big projects, and hobbyists audit the programs they use frequently. In addition, some projects adhere to the reproducible builds guidelines, which ensures the packages you’re receiving are identical to the upstream repo. There’s more work to be done in formalizing and automating these processes but this isn’t a major issue by any means
Just make sure they know anything they put on these big tech platforms are there forever, regardless of what claims they make about “disappearing messages” etc. Do your best to guide them towards encrypted services for their own protection. As much as I hate this, iPhones are a decent recommendation in the US since almost every young person uses iMessage as the default, and that has end to end encryption available. Work to inform them on the dangers of corporate spying and profiling, as well as data leaks and security, and let them have some sovereignty over their platforms. Keeping an eye on them is good; isolating them from important modern social circles isn’t. Inform and educate first and foremost
Random applications that use the play integrity API won’t work on any third party OSes or ROMs. For example I tried to install some Intuit app on my GOS Pixel a while back (credit karma I think?) and it didn’t work at all
Mostly LibreWolf, but I’ve been enjoying Zen Browser recently. It’s based on Firefox but with lots of cool extra functionality baked in. It is still in alpha though and I’ve experienced some bugs, including it crashing my whole system a couple of times, but it’s very promising
Recently, uBlue. It’s more a family of fedora atomic images but it has taken the pain out of immutability for me. I was using Fedora silver blue and later Sericea a while back, but installing codecs from RPMfusion on it never worked properly and my hw acceleration was always broken. I was on NixOS for a while but had sporadic problems that come with NixOS not using an FHS structure. But uBlue just works. Hardware acceleration works out of the box, and I can easily create custom images with BlueBuild. It’s a very nice ecosystem to create a stable, secure, complete base system. And I run nix on top of it for user packages and home-manager to get all the benefits of both worlds
Check out Wayblue, they make some custom universal blue images based off fedora silverblue which includes a hyprland image. I’m running a modified way blue image myself these days and loving it. Technically it’s a secureblue image based on a way blue image but yeah same difference
Was using NixOS but just could not deal with lack of FHS compatibility. Even the workarounds like nix-ld and nix-alien didn’t help with some key scripts I needed to run for secure network verification stuff. So I just migrated to this plus nix/home-manager for my application management
If it’s something that will be mostly interacted with over CLI then kebab case. If GUI then spaces
There is a fully Rust based Unix-like OS out there, it’s called Redox and it’s very cool
Have you tried yabai or amethyst? Both really solid macOS tilers
As somebody else mentioned, using a computer and just taking calls there would work and give you solid control over microphone activation etc. If you really want the landline experience, look into adding a USB handset to that setup. It’ll just act like a mic and headphone from your computer but in the classic phone form factor
