Here are some code samples that could be useful in some projects.
Java AWT's KeyEvents codes to GLFW key codes converter
This functions converts a java.awt.event.KeyEvent Virtual Key (VK) code to a GLFW key code. Link
/**
* All the keys listed in java.awt.event are listed here. If there
* is no GLFW equivalent the function returns -2. Otherwise it returns
* the GLFW code. -1 is reserved for the GLFW's unknown code.
*
* /!\ 1. java.awt.event.KeyEvent does not make any difference between left and right keys for:
* - shift,
* - control,
* - alt.
* So we had to decide, and this function return the code of the right one.
*
* /!\ 2. java.awt.event.KeyEvent takes into account your keyboard layout.
* So if your keyboard is french, and you type "A", GLFW will say that it's Q,
* whereas KeyEvent's VKs will say that it's "A". You have to keep that in mind
* when you convert a KeyEvent's VK to a GLFW key.
* This function will return GLFW_KEY_A with the KeyEvent's key is VK_A.
*
* Version 1.0
* Future updates here: https://gist.github.com/lilgallon/8f3bc1574f9fee318b3b7a879d1b26b4
*
* @param code java.awt.event.KeyEvent VK code
* @return -2 not supported, otherwise it returns the GLFW code.

Progress bar in a terminal using python
This gist is forked from aubricus/print_progress.py.
I updated the code to Python 3, I fixed PEP8 issues and I added the import at the top. Link
import sys
# Print iterations progress
def print_progress(iteration, total,
prefix='', suffix='', decimals=1, bar_length=100):
"""
Call in a loop to create terminal progress bar
@params:
iteration - Required: current iteration (Int)
total - Required: total iterations (Int)
prefix - Optional: prefix string (Str)
suffix - Optional: suffix string (Str)
decimals - Optional: >0 number of decimals in percent complete (Int)
bar_length - Optional: character length of bar (Int)
"""
percents = f'{100 * (iteration / float(total)):.2f}'
filled_length = int(round(bar_length * iteration / float(total)))
bar = f'{"█" * filled_length}{"-" * (bar_length - filled_length)}'
sys.stdout.write(f'\r{prefix} |{bar}| {percents}% {suffix}'),

sys.stdout.write('\n')
