// This is a simple bit of code to do the same thing using the Either monad (e.g. success/failure) and applicatives
// This code is (a) more generic (b) much shorter (c) more type safe

Advanced Functional Programming with Scala - Notes

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.

val square : Int => Int = x => x * x

    This needs to not force delivery of the ListObject.

Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

"""
Logical deletion for Django models. Uses is_void flag
to hide discarded items from queries. Overrides delete
methods to set flag and soft-delete instead of removing
rows from the database.
