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.

As a Go developer, I’m surprised Crystal isn’t more popular
I have seen pcap but not packetz, thanks. Pcap looks unfinished and packetz has not been updated in a long time, but they might be able to make a working capture program. However the popularity and features available in Go regarding packet capture makes it very hard to beat. E.g. the Google gopacket library has 5.6k stars on github and as pretty much every feature you'd want for this sort of stuff built in.

eCapture: capture HTTPS traffic without CA certificates on Android/Linux using Golang.
eCapture implements the feature of saving a pcapng file by eBPF TC, and supports TLS Master Secret Key capturing by eBPF Uprobe. Also, gopacket's DSB feature is supported, based on Decryption Secrets Block (DSB)

Is it common to not have a local dev environment in go?
Well, there is https://github.com/google/gopacket/, you have a package that uses CGo, `pcap`, and then there is `pcapgo`, native Go implementation. Doesn't have all the features but in my case, I was able to use it and remove CGo.

[Go] Try capturing TCP packets
I will capturing TCP packets by gopacket/pcap.

Gain Visibility into Istio mTLS Traffic with Mizu
For example, gopacket uses libpcap by default for capturing the traffic. Libpcap doesn't support network namespaces and we can't ask it to listen to traffic on a different namespace. However, we can change the network namespace of the calling thread and then start libpcap to see the traffic on a different namespace.

Handling TCP connections at scale - Ideas/Suggestions
Exciting question. Many goroutines consume resources accordingly and could also generate latency due to this. If you work under Linux: Have you looked at epoll? Since the system has to do basic connection handling anyway, you can shift or save at least part of the task. gnet is a very good library here to handle epoll & co. Maybe it makes sense to have a look at it or directly use epoll under go.

Show HN: Go-Nbd – A Pure Go NBD Server and Client
Since this heavily involves networking, take a look into using gnet [0]. You might find some interesting performance improvements by using that over just net.Conn.

Millions of Active WebSockets with Node.js
Node is a joke. It's not good for this.
Check out https://github.com/panjf2000/gnet, it also has some links at the end.
