Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

1. CPU-bound
2. Blocking IO
3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
• The link on the answer itself points back at the original post.

Jitpack

For testing purposes, the easiest way to go is jitpack:

resolvers += "jitpack" at "https://jitpack.io"
libraryDependencies += "com.github.User" % "Repo" % "Tag"

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

  // The parts of the type class pattern are:
  //
  //   1. the "type class" itself -- a trait with a single type parameter;
  //
  //   2. type class "instances" for each type we care about,
  //      each marked with the `implicit` keyword;
  //
  //   3. an "interface" to the type class -- one or more methods
