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.

Ask HN: Good book to learn modern networking?
mininet [1] can be used to emulate networks on a single computer. It is used to teach networking concepts.

How do I learn the basics and beyond of networking?
You can learn routing even on a host in Linux with iptables as well as Linux network namespaces via mini net http://mininet.org/ etc. once you’re comfortable there you can start looking at docker networking and also frr as well as gns3 or eve-ng running virtualized routers.

Or instead of using Docker, you can also get a Mininet VM, (optionally) install a desktop environment on it and create any manner of network configurations to tinker with, and use Wireshark to analyse traffic.

You can learn BGP with mininet: https://mininet.org/
You can simulate arbitrarily large networks and internetworks with this, provided you have the hardware to run a large enough number of virtual appliances, but they are pretty lightweight.

Ask HN: Good book to learn modern networking?
Once you're past the fundamentals, if find yourself interested in high-performance networking, I recommend looking into userspace networking and NIC device drivers. The Intel 82599ES has a freely available (and readable!) data sheet, DPDK has a great book, ixy [1] has a wonderful paper and repo. It's a great way to go beyond the basics of networking and CPU performance. It's even more approachable today with XDP – you don't need to write device-specific code.

Speed of Rust vs. C
https://github.com/emmericp/ixy/blob/0e00605be4153b06df06184...
Looks like you're compiling C code with -O2. Does Rust build set -O3 on clang? Did you try -O3 with C? I know it's not guaranteed to be faster, just curious.
