The closest I’ve found in terms of description is https://github.com/feschber/lan-mouse, but the lack of encryption on the connection has discouraged me from using it.
I’m also a paid Synergy user, and it’s frankly comedic how long Wayland support has been on their road map. I’m not convinced it’s ever coming, which means I’m probably only 1-2 distro updates from being forced to use something else

Project mention: What should I do when someone blatantly copy my open-source project on GitHub? | news.ycombinator.com | 2024-08-25This is OasysDB v0.4: https://github.com/oasysai/oasysdb/tree/v0.4.0
I honestly don't know what to do. I know that OasysDB is open-source and thus, free to modify and redistribute. But, I feel like this is more like a plagiarism and a bit unethical to do.
If anyone got similar experience, I'd like to hear some advice.
Thank you in advance.
