Error when installing .deb
Ok, there is a missing dependency, libffi6, which cannot be installed, because it isn't at repos. You can either install it via downloading from other repos (there is a chance in the debian repo), or via compiling on your own (you can start with paying a visit to official site: https://sourceware.org/libffi/). Either way, move carefully and never forget when a dependency is missing, it may be a start of a "missing dependencies hell". And please, be caution, because you can break your system quite easily.

Your favorite binding?
I've been working in implementing libffi into Euphoria so we can call Raylib functions directly. Previously, Euphoria did not support passing structures by value and only occasionally could we get away with "faking" it by passing int type values directly (but not float types). Raylib is the first library I've run into that makes heavy use of passing structures by value, so it's been an interesting challenge. My original proof of concept worked well with libffi built as a shared library, so now I'm working on building libffi directly into the backend of Euphoria. Then we'll be off and running with full support for Raylib!

kivy-ios / initial build with toolchain keeps getting stuck here (checking for suffix of executables...) after updating macOS and xcode... any thoughts? Thanks!
The last line of output is from configure and appears to be during building of libffi recipe - apparently executing the generate-darwin-source-and-headers.py from libffi repository

Installing Python in Ubuntu 20.04
build-essential installs everything required for compiling basic software written in C and C++ in this case Python. Read more... zlib1g-devis the development package of the compression library that implements the deflate compression methods and essential in Python's installation and other installations as well. Read more... libncurses5-dev is the development package for the curses library that provides a terminal-independent screen-painting and keyboard-handling tool. Read more... libgdbm-dev is a development library for GDBM whose functionality is to store key/data pairs in a data file. Read more... libnss3-dev Read more... libssl-dev Read more... libreadline-dev Read more... libffi-dev Read more... libsqlite3-dev Read more... wget Read more... libbz2-dev Read more... In the next step we can either manually download the latest release of Python from the Python Official Release page or use wget which we have installed in previous command. To download using wget, paste the following command in the terminal to download Python in the computer.

Julia ❤ Python
If you have read my earlier posts you know I love multilingual programming. One important part of multilingual programming is how to interface one language with other. Typically this is called FFI or foreign function interface. At the lowest level often there are libraries (aka bindings) to talk across languages or across implementations of same language e.g. libffi. In my undergrad we did a group project where we created language bindings to separate algorithmic part written in python and opencv and X11 logic in c.

is there any resource for JavaScript that explain what kind of logic statement behind each function and why it's give this output and only accept this input etc... ?
It sounds like you want to know how JavaScript is implemented in the browser. The thing is, there is no universal implementation for JavaScript. JavaScript defines a specification that must be adhered to, and then each browser vendor can implement it in whatever way they see fit, as long as it does the specified things. For example (and I'm not saying this is the case) it's entirely possible for Chrome to implement Array.sort() using merge sort, while Firefox implements it as quick sort. You can try to find the source code for the implementation in a certain browser, but that will not be universal. I imagine you can find out how it works in Chrome somewhere in https://chromium.googlesource.com/v8/v8.git, though I'm not sure exactly where.

Looks like these are the two commits, based on the issue number:

What parsing techniques do you use to support a good language server?
It must be a fairly large echo chamber since it has room for Clang, GCC, V8, OpenJDK, Roslyn, etc. (The Zend parser for PHP seems to use some flavor of YACC, but given PHP, I don't know if that strengthens or weakens my point.)

Where can I find the source code JavaScript is written in?
What you're describing is not really possible with JS. Your best bet would be to look at the "V8 engine" source code. It is the interpreter used in Node.js and Chrome (and I think Edge would be using it too as Edge is built on Chromium). But there is nothing forcing Node.js to use V8, there are other JS interpreters. https://github.com/v8/v8
