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.

Securing PyTorch Models with eBPF
In this blog, I will present secimport — a toolkit for creating and running sandboxed applications in Python that utilizes eBPF (bpftrace) to secure Python runtimes.

I haven't come across of any project like that, but in case anyone wants to implement this and doesn't know where to start, here's a way to do it on a freedesktop-compatible linux:
Make a userspace daemon process that adds eBPF tracepoints[0] to open{,_at} etc syscalls which match files of your user directories with specific extensions (e.g. .docx).
Associate PIDs that open those files with their .desktop entries[1]
Store results in some database like sqlite3.[2]
Search this database with your favorite interface, like a CLI script or a GNOME shell search provider[3].
I have seen this Rust project on HN which does something similar but with file attribute syscalls, you can use it as reference: https://github.com/javierhonduco/sweeper

[beetrace]Trace your python process line by line with low overhead!
I develop a python tool that allows you to trace a Python process line by line or the functions' entries and returns. It uses USDT(User Statically-Defined Tracing) probes with bpftrace.

How to check is a linux server is compromised or rooted?
bpftrace and/or bpfcc-tools can also be useful (dpkg -L bpftrace to see available tools). You can monitor files being opened/written at kernel level (opensnoop*, filelife*, filetop*), connections being established (tcp*bpfcc), etc.

Getting notified when a process runs
Similar to this method is bpftrace: https://github.com/iovisor/bpftrace/blob/master/tools/execsnoop.bt

Regarding bpftrace vfs_unlink, why can't I monitor the uid, and the obtained value is 0

Cranelift, Part 3: Correctness in Register Allocation
Both parts (compiler backends & fuzzing) are immensely complicated stuff on their own. I can only imagine the trickery and head scratching that comes with the combination.
I’ve worked on simpler approximations of both [0][1] before and can attest even the simple parts are hard to get working reliably.
