It’s basically like a copy of the original repository. But you can pull in and merge changes from the original, make a pull request for the original to pull your changes. Fork+pull request enables you to contribute to someone else’s repository. Things like Chromium are in part forks of Safari, just that they diverged over time.

I’m far from an expert on communism. But the government, and especially a single person, retaining power over the state and economy is far from communism, it’s more authoritarian. Communism in it’s very base is the citizens owning the means of production, not the state owning those. This in no way is represented in China, where the state has a lot of power over the economy and owns parts of some companies, but there are still capitalists owning factories and workers working there.

When I was there I found those busses really cool. But to my knowledge, they’re being phased out. They essentially combine the worst of bus and tram:

• often shares the street with other cars being more vulnerable to traffic, uses tires (leading to fine particles)
