A python script which starts celery worker and auto reload it when any code change happens.  
I did this because Celery worker's "--autoreload" option seems not working for a lot of people.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

# If you worked with React and JSX you probably noticed that you can't use JS comments when inside JSX sections
# Add this to your Atom init script
# Then add 'ctrl-cmd-/': 'comment-jsx' to your keymap.cson
# Then when you are on a JS/JSX file, just press cmd+ctrl+/ to use JSX-style comments that work with JSX elements
# Is not the most efficient way, but it's the cleanest and reliable one

atom.commands.add 'atom-workspace', 'comment-jsx', ->
  atom.config.set('editor.commentStart', '{/*', {scopeSelector: '.source.js.jsx'})
  atom.config.set('editor.commentEnd', '*/}', {scopeSelector: '.source.js.jsx'})
  for selection in atom.workspace.getActiveTextEditor().selections
