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.

Searchable Linux Syscall Table for x86 and x86_64
This is an old resource, but one that helped me out a lot when writing a fault injection tool for Linux[1].
