It is actually Android 10+, but I think the automatic updates only work for Android 12+ :)
I have it a try and it still has some growth ahead before it is useful in my eyes.
Edit: correction, the latest release is still Android 12+, but the next release will support 10+
Why not go even further? Just switch off the pesky computer entirely. No noise, not even coil whine.
It’s not a messenger, but for locally frequently transferring or syncing a lot of data, I can recommend syncthing. You can use it to configure shared directories, syncthing will use the local network as available (or you can force it to) to transfer files across the devices. We use it for keeping some media, notes, password databases and documents in sync over a bunch of devices. :)
The meaning of copyleft is just that those who use the license have to typically also use the same or a similar license. There is no restriction to who can use it, just to the terms under which they can use it and have to license it.
GPLv3 for example does not allow derivative works to be closed source, while MIT does. In practice this makes some companies hesitant to use GPL-licensed works, but they can, and many do, they just have to abide by its rules. :)
Have to agree, it’s a funny story but charging someone a stupidity rate for nonexistent work isn’t justified by that person being stupid and a pain in your ass. Unless your circumstances force you, you can always just refuse work from customers like this. So many people downvoting this is disappointing.
