If you have faced the error on MacOS X, add these lines to ~/.bash_profile or for a temp fix, use env LANG=en_us.UTF-8 for a quickfix

Overview

This document is a simple resource to create sphinx documentation for projects with python(or not). This isn't exhaustive, but it'll help us get started without much hassle, (which, is typical for sphinx generated documenting)

Prerequisites

For better results, ensure that you're inside a virtual env. This document assumes you're in a Pipenv based environment. Update it later to include other python package management tools (hopefully poetry)

System configurations/utilities that need to be installed on a new system for great productivity

ohmyzsh
- I'm not yet a fan of Fish shell due to posix incompatibility which is causing a lot of troubles when you have to configure niche shell scripts.
howdoi - Get command line answers to common mac/linux problems.
thefuck - Alias it to automatically rewrite the command you wrongly entered.
z - Stop cding to dirs!
tmux - Once you start using this, it's hard to go back. This + Iterm is a heavenly combo
gitflow

Initial configuration for getting started

This assumes that you're creating a simple Ubuntu droplet on digital ocean

Basic installs based on my current experience.

OhMyZsh
- Install Zsh first. sudo apt-get install zsh
- Possibly install zshmarks (Equivalent to fish marks)

Use the following to build functional usable inpage anchors

div-class-name {
  /* This is for a cleaner, and better positioning for the anchor tag */
  display: inline-block;
  padding-top: 100px;
  margin-top: -100px;
  height: 0;
 width: 0;

Dual monitors
When I want to use both monitors, this is the command I run:

xrandr --dpi 276 --fb 7040x3960 \
    --output eDP-1 --mode 3200x1800 \
    --output DP-1-2 --scale 2x2 --pos 3200x0 --panning 3840x2160+3200+0
Here's an explanation of the options:

	indent_style = space
	indent_size = 4
	insert_final_newline = true
	trim_trailing_whitespace = true
