Conquering Kubernetes with Emacs

Specific Annoying workflow

Listing pods with kubectl get pods, then select a pod name and copy paste it into kubectl logs [pod name]

Why?

• I want to streamline my workflow and stop using the terminal
• learn more about kubernetes
• main kubernetes extension for Emacs out there is greedy for permissions

Installing RLS support in Emacs

I tried this successfully with Emacs 25. It may also work with earlier versions.

Django and Postgis on OS X

Install Homebrew

Install a few things with homebrew:

Notice that some packages give you information at the end, read it carefully. To recall that info use brew info like this: $ brew info postgresql

$ brew install python --universal

Step 0:

Get Homebrew installed on your mac if you don't already have it

Step 1:

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

"""
jQuery templates use constructs like:

    {{if condition}} print something{{/if}}

This, of course, completely screws up Django templates,
because Django thinks {{ and }} mean something.

Wrap {% verbatim %} and {% endverbatim %} around those
blocks of jQuery templates and this will try its best
