Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

While you are correct about the stdlib, check out swift-algorithms (https://github.com/apple/swift-algorithms). It's written by Apple and has several interesting methods.
-
Do you use algorithms in Swift?
We used Swift Algorithms once or twice. It just depends on the app. I suggest starting with the WWDC video.

Swift. Algorithms contains chunks(ofCount: 3) but I had to write chunks(totalCount:) myself.

Understanding algorithms
There is also a swift algorithm package that’s a precursor to the standard library if you want to examine legit implementation built into Swift.

Russia has started indiscriminately blocking all OpenVPN/WireGuard connections
Hey there! Lots of experience with this having lived in China for 2 years. I recommend you look into xray-core or v2ray.

Working from China
Normal VPNs that you can see ads all over the place like N*rdVPN won't work, period. The correct way is to rent a few servers from different providers, make sure their ips are not blocked, and build your own V2Ray or Trojan service first. The Chinese gov will not be able to distinguish your Trojan traffic from ordinary https traffic, so the only thing that's sus to them would be the fact that all your traffic goes to one foreign ip, but I've been doing it for a few years without officials knocking on my door so yeah I think it will work for you as well. I don't take responsibility tho, do your research.
- V2ray vs Shadowsocks, which one should I host?
-
Support for other kinds of proxies
Given that every other client is mostly using https://github.com/v2fly/v2ray-core that can be compiled for every architecture/platform that Outline client supports, maybe it's worth investing time into allowing it as a backend. It can even be used for pure shadowsocks since it's for sure more updated than the old golang shadowsocks implementation.
