Do you have any tool to help with that? Ive set this up in the past, but it was pretty hands-on namespacing to get it to work rootless.

It does (not sure how well), but it seems to be a paid feature. Found under Settings -> Split tunneling.

The really simple setup for a single user is just a SSH server with access to storage and the git command. Assuming your laptop and desktop have SSH access to server, you can just:

ssh server git init --bare somerepo
cd somerepo
git remote add server server:somerepo
git push --set-upstream somerepo master #(or main)

and then git clone server:somerepo.

For something slightly higher-tech, I recommend going with Forgejo (the fork of Gitea). It is really easy to set up and low maintainance.

Avoid GitLab for small setups, it is fairly resource hungry.

I would guess real person. Posts without images just get very little traffic, so I assume thats why people are starting to post this.

Is this post about Github seemingly detecting an incorrect licence? The project was relicenced in a later commit, so I dont think this behavior is entirely wrong.
