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.

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

jamesyang124

class A
class A2 extends A
class B

trait M[X]

//
// Upper Type Bound
//
def upperTypeBound[AA <: A](x: AA): A = x

Typically, you can't use a 'new' operator on a generic type. This is because of type erasure.

scala> def create[T] = new T
<console>:7: error: class type required but T found
   def create[T] = new T
                       ^

Scala gives a way of getting around this problem, with the Manifest class.

scala> def create[T](implicit m:Manifest[T]) = m.erasure.newInstance

Logical Operator

• ^ as XOR operator
• & is AND operator
• | is OR operator
• && and || are short-circuit operators.

Bitwise Operation

• 2's complement represent negative number x as its (abs(x) - 1) binary format, then flip each 0 and 1 bit.

Core Goals:

• Can test in up-to-date versions of all major browsers
• Can test on up-to-date versions of all major OSes
• Can test in IE9 (because Bootstrap v4 will support IE9+)
• Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
• Workflow for management of reference/baseline/norm screenshots
