Matrix seems a bit overkill. I think they would be better off with something like gotify.

Take a look at dontkillmyapp.com to see if your phone provider hinders your messages.

There is unified push as Google alternative as well, which works with the schildichat matrix client.

Qwertz.

I teu tried neo couple of years ago but did not use it long enough to get proficient.

I did not find any instruction on the source page on how to actually deploy this. That would be a nice touch imho.

I want a scheme for one with all the buttons. Gimme tactile!

mumble works very well and is foss as well.

I've been with 1984.is for a couple of years now. I think my domains cost around 12 Euros a year each. Their web GUI works fine and I've never needed to contact their customer service, so I cannot comment on that.

There is also an alternate app called paranoids pal on fdroid, that's new and maintained, it did not work reliable on my phone, maybe it works better for you.

And I've used private lock for years and still sometimes lock the phone accidentally, but for me the inconvenience is acceptable because of the security gained.

There is private lock on fdroid, of you shake your phone biometrics get disabled and three phone locks. It's meant as protection from someone grabbing your phone and running away with it but works fine for other emergencies as well.

There is also an aftermarket solution, if you are not on gos, three name is duress on droid.

If you still want the comfort to open your phone via biometrics plus disable biometrics in emergencies there is private lock (fdroid). It will engage when the phone is shaken, e.g. a thief grabs it from your hand while you are typing, or you shake so nobody can force you to open it by fingerprint. The device will be locked and biometrics disabled until you unlock it again. There is also a recently updated app on fdroid with the same features, but it was not as reliable for me so I went back to using private lock.

Openwrt generally works great on x64 PCs. Thiss machine will most likely be more beefy than your home router and could become your main firewall. It can handle adblocking and vpn client for all PCs on the network as well or whatever your need, as openwrt can do many nice things no commercial router can do out of the box. Install openwrt on your home router as well and use that as access point (connected via cable). You will improve your wifi signal as well. If your machine does not come with rj45 lan ports, install usb3 to rj45 adapters to the usb3.0 ports. They will give you the full 1000 mbit speeds.

You need to change the nginx config (for the website you will be hosting your services at. /etc/nginx/sites-available/yourdomain.com

You can reroute all http requests to https in that config.

Watch a video on how nginx works and how to set it up, and then look for example nginx configs for your services. It's a pretty standard setting nowadays so the syntax should be easy to find.

I think nginx can be setup to work locally only, but do you even need it for that? It's primary use is to proxy http requests to the different websites running on your server, enable https via letsencryt and so on, I think.

100% Opnsense. I used to run pfsense for a couple of years but there project was bought by a for profit. Enshitification ensued. They still released their code as per open source licence, but it was not up to closer inspection as it could no longer be used to built the distro from source. They banned perfectly fine hardware from using pfsense as it could not provide hardware acceleration for open-vpn (Aes-ni). The fork opnsense is to be preferred.
