HTML5: async, defer

In HTML5, you can tell browser when to run your JavaScript code. There are 3 possibilities:

<script       src="myscript.js"></script>

<script async src="myscript.js"></script>

<script defer src="myscript.js"></script>

1. Without async or defer, browser will run your script immediately, before rendering the elements that’s below your script tag.
2. With async (asynchronous), browser will continue to load the HTML page and render it while the browser load and execute the script at the same time.
3. With defer, browser will run your script when the page finished parsing. (not necessary finishing downloading all image files. This is good.)

So you need to change your repo config on your PC to ssh way:

1. edit .git/config file under your repo directory
2. find url=entry under section [remote origin]
3. change it from url=https://MichaelDrogalis@github.com/derekerdmann/lunch_call.git to url=git@github.com/derekerdmann/lunch_call.git. that is, change all the texts before @ symbol to ssh://git
4. Save config file and quit. now you could use git push origin master to sync your repo on GitHub

MySQL support is simple to add. In your DATABASES dictionary, you will have an entry like this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', 
        'NAME': 'DB_NAME',
        'USER': 'DB_USER',
        'PASSWORD': 'DB_PASSWORD',
        'HOST': 'localhost',   # Or an IP Address that your DB is hosted on
        'PORT': '3306',
    }
}

You also have the option of utilizing MySQL option files, as of Django 1.7. You can accomplish this by setting your DATABASES array like so:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'OPTIONS': {
            'read_default_file': '/path/to/my.cnf',
        },
    }
}
