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.

How do remote interfaces work in wireshark?
As long as your custom service used the rpcap protocol I'd expect it to be possible. You may find this GitHub page informative, since it includes some rpcap source code and one of the main Wireshark developers appears to be a contributor there.

How to reverse engineer a JSON API on a single page application
mitmproxy can be used to find the HTTP request with the needed data in addition browser dev tools. At some point, I'll explore tcpdump and wireshark to reverse engineer websites for web scraping and share the learnings with you.

Chibicc – A Small C Compiler
(Of course, this consideration should be appropriately downweighted by YAGNI, as threading memory management through prototype or internal utility code can by itself easily force it into very non-prototype amounts of effort.)

Question re C interop, type, for use with std.mem
I am working with libpcap, a library that parses packets captured from tcpdump, which I have cIncluded from Zig.

Implement DevSecOps to Secure your CI/CD pipeline
Nmap and Wireshark, tcpdump tools can be used to scan networks and packets.

Working on Net+, Need Some Direction
Also definitely start looking at tcpdump and wireshark. These are invaluable tools for the non-network engineer that is perhaps a sysadmin or analyst to use for network troubleshooting.

Modding
For future reference, libpcap is a library that Wireshark and many other network analysis tools use to record network traffic. It has its own file format that it can use to save the recorded network traffic to disk.

Linux Debugging
A lot is covered here and here, sar might be useful, getfacl and tcpdump and probably hundred more tools I am not even aware of. The easiest to learn those is to have a problem and identify and solve it with those tools, but to do that you need to know roughly what those tools can do.

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.

Optimal JMX Exposure Strategy for Kubernetes Multi-Node Architecture
Leverage a service mesh like Istio or Linkerd to manage communication between microservices within the Kubernetes cluster. These service meshes can be configured to intercept JMX traffic and enforce access control policies. Benefits:

Open Source Ascendant: The Transformation of Software Development in 2024
Open Source and Cloud Computing: A Match Made in Heaven The cloud is accelerating OSS adoption. Cloud-native technologies like Kubernetes [https://kubernetes.io/] and Istio [https://istio.io/], both open-source projects, are revolutionizing how applications are built and deployed across cloud platforms.

How to Build & Deploy Scalable Microservices with NodeJS, TypeScript and Docker || A Comprehesive Guide
It is a dedicated infrastructure layer that manages service-to-service communication, providing features like load balancing, encryption, authentication, and monitoring. Istio deploys sidecar proxies alongside each microservice instance. These proxies handle communication, providing features like load balancing, service discovery, encryption, monitoring and authentication.

Developer’s Guide to Building Kubernetes Cloud Apps ☁️🚀
In a production environment there will be a load balancer setup with an Ingress Controller, Service Mesh or some type of Custom Router. This allows all traffic to be sent to the single load balancer IP address and then route the traffic to a service based on the Domain name or subpath. We are using a NGINX ingress controller but service meshes like Istio have been becoming the most popular solution to use as they offer more segmentation, security and granular control.

Progressive Delivery on AKS: A Step-by-Step Guide using Flagger with Istio and FluxCD
Flagger is a progressive delivery tool that enables a Kubernetes operator to automate the promotion or rollback of deployments based on metrics analysis. It supports a variety of metrics including Prometheus, Datadog, and New Relic to name a few. It also works well with Istio service mesh, and can implement progressive traffic splitting between primary and canary releases.

gopacket - Provides packet processing capabilities for Go
anthos-service-mesh-packages - Packaged configuration for setting up a Kubernetes cluster with Anthos Service Mesh features enabled
ngrep - ngrep is like GNU grep applied to the network layer. It's a PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
