A udev rule fix for when Chrome can pair with your Keychron keyboard on usevia.app / launcher.keychron.com but fails to actually open it with:

NotAllowedError: Failed to open the device.

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:

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;

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.

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

import cv2

image = cv2.imread('test.jpg')
overlay = image.copy()

x, y, w, h = 10, 10, 10, 10  # Rectangle parameters
cv2.rectangle(overlay, (x, y), (x+w, y+h), (0, 200, 0), -1)  # A filled rectangle

alpha = 0.4  # Transparency factor.

import numpy as np
import cv2

cap = cv2.VideoCapture(0) # Capture video from camera

# Get the width and height of frame
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH) + 0.5)
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT) + 0.5)

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

"""The celery worker has to be started to handle the tasks of celery.

This pattern is followed because we're instantiating the flask application through
flask's application factory. The context of the application is required.

from project import create_app # Flask application factory is used.

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)
