20 Simple Prayers to Inspire and EncourageAlex Blackwell
These prayers aren’t very long, but they will inspire and encourage you to see the good that still lives around you. Consider one of these simple prayers the next time you need to find some peace.
This document provides tips for making your blog brand and PR ready by:
1. Adding PR friendly pages like an "About Me" page and media kit to make it easy for brands to contact you.
2. Creating a disclosure policy page to be transparent about any paid sponsorships.
3. Promoting your other social media channels so brands understand your full online presence and reach.
4. Being mindful of language and tone when discussing brands to avoid coming across as unprofessional.
This document provides guidance on creating an effective media kit for bloggers to use when pitching brands for sponsorships or partnerships. It recommends including sections about the blogger, their blog statistics, past brand collaborations, events attended, blog traffic metrics, and sponsorship opportunities. Maintaining an up-to-date media kit helps bloggers professionally market themselves and their blog to brands, even for new bloggers just starting out. The media kit can be designed as a one-page document or postcard and should highlight key details about the blogger and blog in a clear, well-organized manner.

Small scale cage culture involves growing fish in cages placed in ponds or lakes. It has some key advantages over other aquaculture systems like requiring a lower initial investment. A variety of fish species can be grown in cages, including bluegill, yellow perch, trout, bass, carp, tilapia, catfish and bullheads. Proper stocking densities and maintenance of the cages is important to avoid overcrowding and ensure good growth rates of the fish. Harvesting the cages requires care to minimize stress on the fish.
The document describes the traditional courses that make up a French classical menu. It outlines both a 12-course and 17-course menu. The menus begin with hors d'oeuvres or appetizers and end with dessert and coffee. Between these, courses include soup, eggs, pasta/rice dishes, fish, roasted meats, vegetables, and sweets. Specific dishes are provided as examples for some courses, such as consommé for soup and sole meunière for fish. Details are also given on how certain dishes are plated and served.

2. Basic concept of Inheritance
• Subclass : 상속 받는 클래스
• Superclass : subclass가 상속하는 클래스
• 모든 클래스는 상위 클래스에 속한 메서드, 프로퍼티, 서브스크립트들을 호출하고
접근할 수 있고, 해당 메서드, 프로퍼티, 서브스크립트들을 오버라이딩하여
재정의할 수 있다.
3. Define as a Base Class
어떠한 클래스도 상속받지 않은 클래스, 즉, 상위클래스를 갖지 않는 클래스
4. Define as a Base Class
class Vehicle {
var numberOfWheels : Int
var maxPassengers : Int
func description() -> String {
return “(numberOfWheels) wheels; up to (maxPassengers) passengers”
}
init() {
numberOfWheels = 0
maxPassengers = 1
}
}
let vehicle = Vehicle()
베이스클래스 정의 부분
Vehicle의 새로운 인스턴스 생성
5. Subclassing
• 하위클래스를 정의한다 => 기존 클래스를 기반으로 새로운 클래스를 생성하는 것
• 기존 클래스의 모든 특징을 상속받고, 재정의할 수 있다.
Basic structure Of subclass
class SomeClass : SomeSuperClass {
//class definition goes here
}
6. Subclassing
class Bicycle : Vehicle {
init() {
super.init()
numberOfWheels = 2
}
}
let bicycle = Bicycle()
println(“Bicycle : (bicycle.description())”)
//Bicycle : 2 wheels; up to 1 passengers
7. class Tandem : Bicycle {
init() {
super.init()
maxPassengers = 2
}
}
Subclassing
let tandem = Tandem()
println( Tandem : (tandem.description());)
//Tandem : 2 wheels; up to 2 passengers
8. Overriding
• 하위클래스에서 인스턴스 메서드, 클래스 메서드, 인스턴스 프로퍼티,
서브스크립트에 대해 자신만의 커스텀 구현체를 제공하는 것
• 즉, 기능의 재정의
• 상속한 특징을 override하기 위해서는 반드시 앞에 override 키워드를 붙인다.
• Override 키워드가 없는 override는 컴파일 에러!
9. Accessing superclass, methods, properties and subscripts
• super 접두사를 통해 상위클래스의 메서드, 프로퍼티, 서브스크립트에 접근 가능
• someMethod()가 override 됐을 경우 super.someMethod()를 통해 접근
• someProperty가 override 됐을 경우 super.someProperty를 통해 접근
• someIndex가 override 됐을 경우 super[someIndex]를 통해 접근
10. Overriding Methods
class Car : Vehicle {
var speed: Double = 0.0
init() {
super.init()
maxPassengers = 5
numberOfWheels = 4
}
override func description() -> String {
return super.description() + “;” + “traveling at (speed) mph”
}
}
let car = Car()
println(“Car : (car.description())”);
//Car : 4 wheels; up to 5 passengers; traveling at 0.0 mph
11. Overriding Properties
• 상속한 프로퍼티를 오버라이드하려면 그 프로퍼티가 stored 혹은 computed
프로퍼티인지 관계없이 커스텀 접근자와 설정자를 제공
• 하위클래스는 오로지 상속한 프로퍼티의 이름과 타입만 알게 됨
• 항상 오버라이딩하려는 프로퍼티의 이름과 타입을 동일하게 설정
• 읽기만 가능했던 프로퍼티를 읽기, 쓰기 둘다 가능하게 오버라이딩 가능
• 하지만, 읽고 쓰기가 가능했던 프로퍼티를 읽기만 가능한 프로퍼티로 오버로딩하는 것은
불가능
12. Overriding Properties
class SpeedLimitedCar : Car {
override var speed : Double {
get {
return super.speed
}
set {
super.speed = min(newValue, 40.0)
}
}
}
let limitedCar = SpeedLimitedCar()
limitedCar.speed = 60.0
println(“SpeedLimitedCar : (limitedCar.description())”)
//SpeedLimitedCar : 4 wheels; up to 5 passengers; traveling at 40.0 mph
13. Overriding Property Observers
• 프로퍼티 관찰자는 상수 혹은 읽기 전용 프로퍼티에 추가될 수 없음
• 프로퍼티 값은 다시 설정될 수 없으므로 willSet() 혹은 didSet()을 제공하는 게
적절하지 않음
• 오버라이딩 설정자와 오버라이딩 프로퍼티 관찰자를 동시에 제공 불가능
15. Preventing Overrides
• Override를 방지하려면 @final을 첫 키워드에 표시
• 하위클래스 내에 final 메서드, 프로퍼티, 서브스크립트를 오버라이드하면
컴파일 에러 발생
• 전체 클래스를 final로 만들려면 class 앞에 @final 표시, 하위 클래스를 final
클래스로 만들려면 컴파일 에러 발생
