Yes my answer is for use with Let’s Encrypt.

Fair, I don’t know why I read OPs post as asking for let’s encrypt certs. Internal CA is indeed an option.

They do not. See my other reply about DNS verification.

OP is asking for cases where you don’t want to allow the service (or reverse proxy) to be accessible via the web.

You can use the DNS verification method. Either using nsupdate with bind or what ever protocol your DNS provider and favorite ACME (certbot, acme, lego, etc) utility supports. As long as your DNS server is publically reachable that will work, even if the subdomain itself doesn’t exist publically.

You don’t need evolution for gnome-contacts and I’m not sure how much more lightweight a contact app can get. It literally does nothing but list and edit contacts, and works with dav via gnome-accounts.

Found this not so long ago and it literally made me sad I don’t manage an LDAP anymore!

What’s wrong with gnome-contacts?

Look into Snapcast

You can be pedantic if you want, but it’s pretty obvious OP meant RS232 serial.

As mentioned in the other comments, actually encrypted chat.

B64 isn’t encryption.

There’s a similar story of the sorts with “libertarian” ideology (a word stolen from French Anarchists - who were without a doubt leftists). Milton Friedman was paid by the oil industry to come up with it, and they peddled it through the Real Estate Association of America.

Also the “desktop” web app requires to be paired with an instance of the mobile app.

I wished moxie would spend a little less time flying helicopters and trekking in Tajikistan, and reflect on the need to support non proprietary platforms.

Flare? It’s hardly complete. Can’t even use it as a primary device.

As for the desktop app, it’s not exactly mobile oriented.

FreeCAD’s Python functions are all well organized in different modules. Some of them are already loaded (imported) when you start FreeCAD. Just try:

dir()

Might I ask, why exactly do you feel the need to have a webapp for CAD rather than a hard client?

Unrelated but BTW FreeCAD is fully python scriptable. In fact, as I understand it, every operation is first translated to python code.

To your point, I tried for a bit and truly the one thing I couldn’t live without was Signal.
