The error message is very detailed and there is nothing to add to it.

If you want to install an application/CLI tool, use pipx or your system package manager. If you want to install a library, use a virtual environment (e.g. by using python -m venv) or your system package manager.

I think you understood their comment wrong. In your code (e.g. label.add_css_class("green");) you don’t use a dot, but in the CSS stylesheet. It works the same as with HTML/JS/CSS.

Well, that’s CSS :D

Note that if you create a custom Widget class, you can set a CSS name, wich isn’t a CSS class and doesn’t use a leading dot.

Just use label.add_css_class(), label.remove_css_class() or label.set_css_classes() and make sure to properly load your CSS style sheets, this is usually done by including them as a resource alongside .ui files and icons. If you are using libadwaita, you can also use its predefined style classes.

This is extremely sad. I use Syncthing a lot to sync documents between my phone an my computer.

The main benefit over client/server-based solutions are that it always works.
No network connection? No problem, the files are all stored locally.
I broke my home server again? No problem, the devices can talk directly to each other.

For this sort of things, LibreOffice Draw can be really good. I even used it in the past to create memes.

Unlike X11, Wayland was never intended to be network transparent. As others say, solutions like waypipe and more tradionally RDP and VNC exist.

SPRIND GmbH is also known as „Bundesagentur für Sprunginnovationen“ and owned by the Federal Republic of Germany. See https://de.wikipedia.org/wiki/Bundesagentur_für_Sprunginnovationen and https://www.sprind.org

It supports any ONVIF compatible IP camera as well as USB cameras and the raspberry pi camera module

MotionEye used to be the go-to solution.

I am not sure about the current state of the project (the python 2/3 transition took a long while, there are only pre-releases using a modern python version).

And it’s just some Discourse instance…

They even implemented it in Firefox: moz://a redirects to https://www.mozilla.org/en-US/about/manifesto/

It think this comment explains it really well: https://sh.itjust.works/comment/13239406

I don’t like it. He is just perpetuating the endless stereotypes that plague linux and harm linux adoption.

If you are using a somewhat stable distro and don’t have weird hardware, you don’t need to “write your own driver” etc. A lot more people “punch themselves in the face” by using a buggy, ad infested, data harvesting operating system even though they just need a web browser.

I think Germany’s done it twice now.

It was Munich and they switched back to Windows after M$ moved their German headquarters to Munich.

Thanks for the explanation

I don’t know moonlight and don’t know what you mean by “certain typed documents”, but AFAIK, OSMC is just Raspbian with some additional stuff. What I am saying is that media playback works just fine performance-wise for some media formats.

I run OSMC on a Pi 4 and it plays h.265 & h.264 videos at 1080p and h.262 at 576p just fine.
