ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Description	Syntax
Get the length of a string	`${#VARNAME}`
Get a single character	`${VARNAME[index]}`

Web IDEs

ideone Ideone is an online compiler and debugging tool which allows youto compile source code and execute it online in more than 60 programming languages and share links to the code.
repl.it Like ideaone, can also install missing Python packages.
Onlilne GDB Online compiler and debugger forC, C++, Python, Java, PHP, Ruby, Perl, Pascal, Fortran, Haskell, Objective-C, Assembly, HTML, CSS, JS, SQLite, Prolog, and more.
Coding Ground Advanced IDEs for C/C++, C#, GO, Java, PHP, Perl, Python, Octave/MATLOAB, R, Ruby, Scala, and compiler/interpreter for many other languages and frameworks.
JDOODLE very similar to ideone but a somewhat different set of languagse/compilers.

	A pure python implementation of the CPython GIL

	Note: this code will not run if you will try to execute it, because it's missing bytecode execution logic.

	Originally from: https://rushter.com/blog/python-gil-thread-scheduling/

	Some things to note:
	- Each thread executes its code in the separate execution_loop which is run by the real OS threads.
	- When Python creates a thread it calls the take_gil function before entering the execution_loop.
