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.

eBPF: Unleashing Kernel Magic for Modern Infrastructure
But wait, there's more! Enter the BCC toolkit and library, your trusty sidekick in simplifying the arcane art of writing eBPF applications. With BCC by your side, you'll be wielding eBPF like a seasoned pro in no time.

Linux: Easy Keylogger with eBPF (2018)
Nice - I normally use [bash-readline](https://github.com/iovisor/bcc/blob/master/tools/bashreadlin...) when coworking/co-inhabiting a server or training someone.

eBPF Documentary
One of the big wins is not so much “build and run your own stuff” but there are very nice low-cost (in terms of compute) performance utilities built on eBPF
https://github.com/iovisor/bcc
There are so many utilities in that list; there’s a diagram midway down the readme which tries to help show their uses. bcc-tools should be available in any distro.
Also, Brendan Gregg does a ton of performance stuff that is worth knowing about if you check out his other work. Not eBPF only. Flame graphs are useful.

Uprobes Siblings - Capturing HTTPS Traffic: A Rust and eBPF Odyssey
In this article, we'll build a basic version of an HTTPS sniffer, inspired by bcc-sslsniff.py, but we'll use Rust and Aya. We're going to demonstrate the capabilities of uprobes by employing uprobe and uretprobe along with familiar maps like PerCpuArray, HashMap, and PerEventArray. This will be a straightforward example to help us explore how uprobes function.

Issue XDP_REDIRECT on other interface in the same namespace
As xpd program I am using the BCC example xdp_redirect_map.py in skb mode as my NIC does not support native mode, attaching the program to veth2 and a dummy function to veth3

Why can't MacOS just TELL ME which program is using the drive I'm trying to eject rather than just have me guess?
That said, after I learned about how to use lsof, I found this little free app called =Sloth (and its github page ), which is just a nice native Mac app serving as a GUI for lsof. It'll let you know exactly which process to quit or kill so your drive can eject happily.

The Icelandic Saga Database
Random fact; this website is created and maintained by Sveinbjörn Þórðarson who also made Platypus (https://github.com/sveinbjornt/Platypus) and Sloth (https://github.com/sveinbjornt/Sloth) — software that Mac nerds might be familiar with.
Sveinbjörn is a ball of energy that just radiates positives for human society.

Really not liking Xcode these days.

Open Ports for macOS – Never Google “How to kill a process by port?” again
a very nice, open source, app that provides similar functionality but also shows open files is Sloth (https://sveinbjorn.org/sloth).
