Installing Ghost Blogging platform

Installing Ghost is much more complicated than it is described in the docs. Here are a few additional steps needed do get it up and running.

####Clone the git repository I cannot get to work any of the random releases files I've downloaded, so start off with a fresh repo and follow the few steps that the guide actually provides.

git clone https://github.com/TryGhost/Ghost.git ghost
cd ghost
npm install
npm start

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

Hard things about ports being Tasks in Elm

evancz Mar 23, 2017 00:43
Just so folks are aware, one of the hard things about having ports just be a Task is the following. Right now, a Task is guaranteed to terminate with an error or a result. The only way it could be otherwise is if you have something of type Task Never Never Now, if you are calling out to random JS that is written by anyone, that guarantee goes away. You have to call some callback to give the value back to Elm, but what if that is never called? Maybe there's an error, maybe there is a weird code path. Now Elm code can "leak" tasks that never get completed because of problems in JS code. One way to protect against this is to have timeouts, such that there is some guaranteed end. My point here is just that it is more complicated than "what if it was a task?" and then everything would be nice.
