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.

Awesome CTF : Top Learning Resource Labs
PicoCTF - The platform used to run picoCTF. A great framework to host any CTF.

Need advice on building a container provisioning system (think HackTheBox)
As /u/anachronisticadmin hinted at, devil’s in the details - here is a blueprint for a CTF-framework: https://github.com/picoCTF/picoCTF

Beej's Quick Guide to GDB (2009)
There is also GEF, which is widely used by the reverse engineering and CTF community.

How do you use gdb without the tui? Are there advantages? Or just describe your GDB workflow.
If you are on Linux, install GEF and be happy.
- TF2 on Linux is running incredibly poorly, reporting 1200%+ CPU usage. Steam also appears to have some sort of memleak and infinite loop/callback going on leading to absurd CPU usage over time.
-
Any good and easy-to-use C debuggers?
If you are in linux, I recomend none of them (haha) because you should get more used to GDB a little bit. You just need to install some good visualizers likes GEF, for example.
- Emulating an emulator inside itself. Meet Blink

Are there any cpu emulators that could help me learn i386 assembly?
https://github.com/hugsy/gef, https://hugsy.github.io/gef/, https://hugsy.github.io/gef/commands/context/ ("Values in red indicate that this register has had its value changed since the last time execution stopped.")
- What plugins do you recommend for ExploitDev or RE and why?
- Awesome TUI tools

Fully Dockerized Linux kernel debugging environment
The attached debugger is not just raw GDB but is using https://hugsy.github.io/gef/ to make debugging less of a pain. It's still not perfect but helps plenty already.

Debugging with GDB
I still struggle with GDB but my excuse is that I seldom use it.
When I was studying reverse engineering though, I came across a really cool kit (which I've yet to find an alternative for lldb, which would be nice given: rust)
I'd recommend checking it out, if for no other reason than it makes a lot of things really obvious (like watching what value lives in which register).
https://github.com/hugsy/gef
LLDB's closest alternative to this is called Venom, but it's not the same at all. https://github.com/ovh/venom
What are some alternatives?
