Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?

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

-- Our goal is to create a type describing a list of events. This is our
-- type-level DSL.
-- We will then use typeclass resolution to "interpret" this type-level DSL
-- into two things:
-- 1. A comma-separated list of events
-- 2. A method that, when given an event name and a payload, will try to parse
--    that event type with the payload. A form of dynamic dispatching
--
-- To model a list of types we will use tuples. You can imagine the list of
-- types "Int, String, Char" to look like:
