1. The Layer Tree

Core Animation's original name is Layer Kit

Core Animation is a compositing engine; its job is to compose different pieces of visual content on the screen, and to do so as fast as possible. The content in question is divided into individual layers stored in a hierarchy known as the layer tree. This tree forms the underpinning for all of UIKit, and for everything that you see on the screen in an iOS application.

In UIView, tasks such as rendering, layout and animation are all managed by a Core Animation class called CALayer. The only major feature of UIView that isn’t handled by CALayer is user interaction.

There are four hierarchies, each performing a different role:

Integralist

• defprotocol: defines an interface
• deftype: create a bare-bones object which implements a protocol
• defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

springloaded는 개발환경에서 .java클래스를 수정했을 때 변경된 클래스파일만을 재로딩하는 도구입니다. Local PC에서 수정과 Tomcat재시작을 줄이는데 도움이 됩니다.

다만 JRebel도 그러하듯이 모든 경우 완벽한 리로딩이 되지는 않습니다. 메서드추가,수정시에는 잘 반영됩니다. 그러나 아래와 같은 경우에는 자동반영이 되지 않습니다.

• 상속구조의 변경
• Reflection정보가 Cache된 것
• XML설정 수정 (이 부분은 프레임워크 특화된 구현이 들어가지 않으면 당연히 어렵습니다.)

그래도 많은 경우 Tomcat재시작없이 개발을 이어갈 수 있다면 없는것보다는 생산성에 도움이 되리라 생각합니다.

기술 문서를 쓸 때 주의해야 할 몇 가지

독자 배려

자신의 생각과 할 일을 정리하는 것이 기술 문서의 목표가 될 수는 없다. 먼저 독자를 식별하라. 그리고 독자를 배려하고 독자 입장을 생각하며 문서를 작성하라.

텍스트 파일의 장점

중요한 정보를 위키나 깃(Git)에서 텍스트로 작성하지 않고, 워드나 파워포인트 같은 이진 문서로 작성할 때마다 당신의 동료는 접근성, 가시성, 버전 관리 등 다양한 문제로 고생할 것이다.
