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.

A Compiler Writing Playground
Thank you.
There is also OMR
https://github.com/eclipse/omr
but I'm not sure how powerful that is.
I started writing a simple multithreaded interpreter that processes an imaginary assembly. Here's a program in that imaginary assembly that sends integers to other threads and then sends a jump instruction to another thread to jump to some code.

Chibicc – A Small C Compiler
I am interested in this too. I would do different tradeoffs. I am more interested in optional garbage collection, the parallelism and async story in the language such as threading and coroutines or both together.
I suspect combining garbage collection, exceptions, closures, tail call optimisation, parallelism, JIT compilation and coroutines is difficult to do orthogonally.
On eatonphil's discord someone recently shared this link: This is a framework for building high performance language runtimes
https://github.com/eclipse/omr
I am currently implementing a programming language and compiler and interpreter in my multiversion-concurrency-control repository.

IBM joins Eclipse Adoptium and offers free certified JDKs with Eclipse OpenJ9
I like this part "We continue to employ dozens of developers that work directly and openly in the Eclipse OMR and Eclipse OpenJ9 projects at GitHub. IBM doesn’t produce a separate enterprise version of OpenJ9; we don’t hold back any of the innovation in our runtime."

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.
What are some alternatives?
OpenJ9 - Eclipse OpenJ9: A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR (https://github.com/eclipse/omr) and combines with the Extensions for OpenJDK for OpenJ9 repo.
npcap - Nmap Project's Windows packet capture and transmission library
tesseract-ocr - Tesseract Open Source OCR Engine (main repository)
tcpdump - the TCPdump network dissector
clauf - A C interpreter developed live on YouTube
gopacket - Provides packet processing capabilities for Go
ImHex - 🔍 A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.
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.
x64dbg - An open-source user mode debugger for Windows. Optimized for reverse engineering and malware analysis.
mimalloc-bench - Suite for benchmarking malloc implementations.
ClickHouse - ClickHouse® is a free analytics DBMS for big data
WebKit - Home of the WebKit project, the browser engine used by Safari, Mail, App Store and many other applications on macOS, iOS and Linux.
