Applied 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

BOSH Links: Why and How

Audience: anyone in the BOSH ecosystem, whether you work on something open-source or proprietary

"BOSH Links" is a feature which simplifies how data is shared between BOSH-deployed jobs that need to collaborate with one another (e.g. a web server and its backing database). Like many BOSH things, the whole "BOSH Links" thing can seem counter-intuitive at first, and it may not be clear why things are the way they are. This note hopes to show some of the powerful benefits of BOSH Links, and provide examples and explanations that make things more intuitive.

Why?
BASIC: A simple problem statement
BASIC: Putting the puzzle pieces together
ADVANCED: But what about...

Instead of writing a long article I wrote this summary to give a good overview about software systems scalability by listing the main terms and methodologies that widely used to build stable systems that are able to scale and handle the increasing amont of users and data.
