Prerequisites

Enable USB debugging (and allow RSA key fingerprint from connected computer)
Allow OEM unlocking
Have Android SDK installed on computer

Build

Clone kali-nethunter repository
Pull a Python Docker image python:2.7.14-jessie (even my local fresh macOS has problem of building)
Run Python Docker container: docker run -it -v [your-cloned-kali-nethunter-repo]:/root/kali-nethunter python:2.7.14-jessie bash
Build: python /root/kali-nethunter/nethunter-installer/build.py -d flounder --nougat --rootfs full (you have to build the Nougat version on your own, because the latest official version is only for Marshmallow)

Homebrew and Symlink Issues

Introduction

This works to install Open GApps into the Android Emulator, working around the issue where the system partition is too small.

With it, I can get Google Play installing into the emulator. Tested on KitKat (API 19), Lollipop (API 21) and Oreo (API 27).

It's tested on MacOS.

Instructions

Note-taking for What the heck is the event loop anyway? by Philip Roberts.

JavaScript: a single-threaded, non-blocking, asynchronous, concurrent language.

JavaScript has a call stack, an event loop, a callback queue, some other APIs and stuff.

V8 has a call stack and a heap.

DOM, Ajax (XMLHttpRequest), setTimeout are from Web APIs provided by browser.

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

	node {
	echo 'Results included as an inline comment exactly how they are returned as of Jenkins 2.121, with $BUILD_NUMBER = 1'
	echo 'No quotes, pipeline command in single quotes'
	sh 'echo $BUILD_NUMBER' // 1
	echo 'Double quotes are silently dropped'
	sh 'echo "$BUILD_NUMBER"' // 1
	echo 'Even escaped with a single backslash they are dropped'
	sh 'echo \"$BUILD_NUMBER\"' // 1
	echo 'Using two backslashes, the quotes are preserved'
	sh 'echo \\"$BUILD_NUMBER\\"' // "1"
