These are things I've said in the last 9 months that I didn't think would be controversial... but very much were.

• We should write documentation
• We shouldn't be sharing one big dev environment for local development where we're all sharing the same state

Docker Dream Land

This document describes an idealized version of what a dream development environment that uses Docker looks like based on my own experience.

What it looks like for a dev joining an existing project

Below describes what working on a Dockerized project looks like to a dev starting with that project for the first time.

Docker Painpoints for Development

What is this?

This document is meant to point out pain points with using Docker for development environments. It rates each pain point w/ a pain level of 1 to five stars (1 being low, 5 being high).

Each issue will highlight:

Code Review

The time for:

• mentorship
• exemplifying how code review well
• checking test coverage
• design discussions
• enforcing style guides

    Couldn't match expected type ‘Int’ with actual type ‘a’
      ‘a’ is a rigid type variable bound by
          the type signature for
            splitWhen :: (a -> Bool) -> [a] -> ([a], [a])
          at src/Data/List/Extras.hs:27:14
    Relevant bindings include
      n :: a (bound at src/Data/List/Extras.hs:29:23)
      xs :: [a] (bound at src/Data/List/Extras.hs:28:13)
