Human friendly format without using math libraries
"""
Write a function in Python called ‘humanSize’ that takes a non-negative number
of bytes and returns a string with the equivalent number of ‘kB’, ‘MB’, ‘GB’,
‘TB’, ‘PB’, ‘EB’, ‘ZB’, or ‘YB’,between [0, 1000), with at most 1 digit of
precision after the decimal.
If the number of bytes is >= 1000 YB, return this number of YB, for example 5120 YB.

Steps to connect to mysql using cpp (Linux)
  1. Install mysqlconn-dev library, example for Debian: apt-get install libmysqlcppconn-dev
  2. Download mysqlconn library
  3. Download the generic tar or install directly for your favorite flavor
  4. Download and install boost. This lib is needed by mysqlconn.
  5. If using generic, uncompress and take note of where is located.
  6. Create a cpp file to test. You can use this example
  7. Compile including the needed libraries. For example if you used used the generic lib, it should be something like this:
g++ -o test -Ipath/to/connlib/include/jdbc -I/path/to/boost test.cpp -lmysqlcppconn

An example of a server configuration for using node and postgres on heroku
// Since It's not a good idea to have everything on the server.js I moved the pool creation to this file
// Require the pg module
const { Pool } = require('pg');
// You can either do this or check if we are in production like in server.js
// In this case if the DATABASE_URL is declared we use it to the connection
const { DATABASE_URL } = process.env;
