Adrian -

I appreciate that you spent time in writing this post. I know I've been up until 2am writing similarly long ones as well. I will take responsibility for having what is likely an irrational response (I blame Twitter for that) to the term "NoOps", but I invite you to investigate why that might be. I'm certainly not the only one who feels this way, apparently, and thus far have decided this issue is easily the largest distraction in my field I've encountered in recent years. I have had the option to simply ignore my opposition to the term, and just let the chips fall where they may with how popular the term "NoOps" may or may not get. I have obviously not taken that option in the past, but I plan to in the future.

You're not an analyst saying "NoOps". Analysts are easy (for me) to ignore, because they're not practitioners. We have expectations of engineering maturity from practitioners in this field of web engineering, especially those we consider leaders. I don't have any expectations from analysts,

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

First, install nginx for mac with "brew install nginx".

Then follow homebrew's instructions to know where the config file is.

1. To use https you will need a self-signed certificate: https://devcenter.heroku.com/articles/ssl-certificate-self
2. Copy it somewhere (use full path in the example below for server.* files)
3. sudo nginx -s reload
4. Access https://localhost/

Edit /usr/local/etc/nginx/nginx.conf:

    def emit(self, data, event=None):
        """

        """
