DEV Things to Remember

Python
  - A directory that contains a __main__.py file can be executed directly by the python interpreter
  - If that directory contains a __init__.py file it can be executed as a module.
  - If using MatPlotLib you might receive a "Python was not installed as a framework..." error.
    - Create a file `~/.matplotlib/matplotlibrc` and populate it with `backend: TkAgg` to solve the problem.
    - Why? Who fuckin knows?
    
Jupyter
  - When installing a Javascript Jupyter kernel following the following page:
    - https://github.com/n-riesco/ijavascript
    - The steps on that page can apparently only be run with Python 2.
  
Gunicorn
  - Startup command
    - gunicorn -w 2 -b localhost:9000 app
    - Must create 2+ workers so that resources can be loaded simultaneously
  - --log-level only applies to internal error logs
    - Set log level in code/with config
    - Might be able to use gunicorn's other config to control this
  
Webservers
  - Simplfy API responses
    - Content should be simple if even needed
    - Status code should be 200, 400, 404 or 500, unless there is another highly compelling option
    - Other details should be included in headers to allow maintaining a response API
    
VueJS
  - Mutating parent state from within child components
    - Declare a prop on the child
    - Map the parent datum to the child prop when instantiating the child component
      - `<child-component :child-prop="parentDatum"></child-component>`
    - In child template/code
      `$emit(some-event, 'the data to pass to event handler') // Data can be arbirarily complex` 
    - Attach event handler (@some-event) when instantiating the child component
      - In event handler mutate parent data (increment, push to array, change value completely, etc.)
      - When mutating the value in markup, `$event` represents the value passed as the second argument to `$emit()`
      - When mutating the value via a method, the first argument passed to the method will be
        the value passed as the second argument to `$emit()`
