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.

Searchable Linux Syscall Table for x86 and x86_64
There's a pretty decent set of autogenerated lists present in strace source, see e.g. https://github.com/strace/strace/blob/master/src/linux/64/io...

Is it possible to get `strace` to append to a file immediately?
I guess the only way to find out is to make use of the fact that strace is OSS. https://github.com/strace/strace As I mentioned this is outside my skill level, but looking at the top level files I can see many references to output buffering so you may well be SOL.

Is systems programming dead?
No no noooo. Nope. Not even close. There's mountains of work down here. It's just less sexy, and less visible. There are a surprising number of ubiquitous sysutils that have very few relative github stars or whatever. Look at https://github.com/strace/strace for example. Laughably few stars compared to the flavor of the month javascript framework -- but does that mean that I can't find it on all of our *nix machines? Nope, it's on basically all of them.

Any Systemcalls/processes pro who can help me?
Maybe taking a look at the strace source repository can help you along.

Using Distributed Tracing in Microservices Architecture
Program(Process) Tracing (ptrace) Tools: Establishes tracing operation during the execution of the application. Contains the traces of the index of instructions executed and the data referenced during execution. These are greatly used by developers for debugging purposes. Some examples of ptrace tools are, Strace, Ltrace, Opensnoop, and Valgrind Lackey.

The Gems of Moreutils
For execsnoop, people running systems with DTrace can find the same:

On macOS Monterey+ you'll probably have to install the Kernel Debug Kit per:
* https://developer.apple.com/forums/thread/692444
The Linux variant was written Brendan Gregg (who previous did a lot of work on Solaris, where DTrace was created):

Track what process modify file
It's not a library you can use but you might be able to take inspiration from something like opensnoop.

Does any one know how to make perf in wsl2, show the info like Cycles, Instructionis.
There are several tools that might go by the name 'perf', are you talking about this one? https://github.com/brendangregg/perf-tools

Which kernel functions are called upon page cache accesses?
I have an application and I'd like to measure its page cache hit/miss numbers. I found this tool called cachestat by Brendan Gregg, which uses the ftrace tool to count the number of 4 specific functions (mark_page_accessed(), mark_buffer_dirty(), add_to_page_cache_lru(), and account_page_dirtied()) to find out the total number of page cache accesses and page cache misses. Detailed information can be found here, but basically, total number of page cache accesses and page cache misses can be calculated as below:
