Install mutiple Erlang and Elixir with vfox
Theoretically, you could install any version that appears in https://github.com/erlang/otp/releases. Since it is compiled and installed from source, the installation process will take some time. When you see the following message, the installation is complete.

Why are there so many languages?
Funny that you should mention Erlang. Looking at the Github for Erlang, it appears that the source for Erlang is 16.8% written in C. I would bet these are not the least important bits of the whole thing. So, Erlang depends on C.

Erlang: More Optimizations in the Compiler and JIT
It looks more like some of the JIT improvements made it profitable to manually unroll some loops in the base64 module: https://github.com/erlang/otp/commit/a03cf1601605dee767cd9d5...

Mixing sync and async views in the same application
https://github.com/erlang/otp as far as I know. It's somewhat confusing and I honestly couldn't say exactly where the BEAM VM or OTP or ERTS (Erlang Runtime System) start and end. I've never dug into it. I just install Elixir and sometimes Erlang through the ASDF tool, which does all the compiling for me.

PwnTools for Exploit Development
The Pwntools library stands out as a sophisticated toolset for CTF enthusiasts and security researchers. It aids in creating and executing shellcode, designing payloads, and interacting with remote processes. For instance, the context feature allows developers to switch between different architectures effortlessly, while the 'tube' module streamlines the communication between local and remote processes. And it's not just limited to Linux; the library has support for various platforms including Windows, making it versatile and comprehensive.

What is Calypso?
One library that I may eventually make which will probably not be an officially maintained library but which I will maintain myself will be a partial or full port of pwntools (a library written in Python for CTFs) to Calypso. For more information on CTFs, atan made a pretty cool post about them:
- Use pwntools for your exploits

anybody know good packet crafting resources?
Scapy is great if you're attacking low level networking protocol stacks like TCP/IP or UDP. In that case, you may be modifying packet headers and such. Otherwise, it's much easier to just use the Python socket module and craft your custom payload in Python. Even better is the pwntools module.
