DOM Performance (Reflow & Repaint) (Summary)

DOM Performance

Rendering

  • How the browser renders the document
    • Receives the data (bytes) from the server.
    • Parses and converts into tokens (<, TagName, Attribute, AttributeValue, >).
    • Turns tokens into nodes.
    • Turns nodes into the DOM tree.
  • Builds CSSOM tree from the css rules.

iOS Core Animation: Advanced Techniques, Part 1: The Layer Beneath

Author: https://www.cyanhall.com/

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:

Autoboot Boot2Docker on System Startup

I came across this when I found several solutions that didn't work for me. They all had there very own problems, they either had a debug option in it (which I found guilty of not starting my job after several hours of debugging) or other unnecessary keys.

To make this plist work, you should may create the corresponding log files before and give them the necessary permissions (770 worked for me, though it's maybe too much).

  1. Create the plist under ~/Library/LaunchAgents/com.user.boot2docker.plist
  2. run launchctl load ~/Library/LaunchAgents/com.user.boot2docker.plist
