patch-edid.rb

A script to fix EDID problems on external monitors in macOS.

Instructions

1. Connect only the problem display.

2. Create this directory structure (if it doesn't already exist):

rsms

@interface MyThing {
  NSMutableDictionary* _devices;
    // <NSNumber*deviceID>=<NSNull> while connecting
    // <NSNumber*deviceID>=<PTChannel> while connected
}

- (void)startListeningForDevices {
  NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];

  [nc addObserverForName:PTUSBDeviceDidAttachNotification object:PTUSBHub.sharedHub queue:nil usingBlock:^(NSNotification *note) {

O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."

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:

// #!Swift-1.1
import Foundation


// MARK: - (1) classes

// Solution 1:
//  - Use classes instead of struct
// Issue: Violate the concept of moving model to the value layer

// macOS x86_64 syscall works as follows:
// Syscall id is moved into rax
// 1st argument is moved into rdi
// 2nd argument is moved into rsi
// 3rd argument is moved into rdx
// ... plus some more
// Return value is stored in rax (where we put syscall value)

// Mac syscall enum that contains the value to correctly call it
enum Syscall: Int {
