3 Ways of Generating SSH Keys: OpenSSH, OpenSSL and GPG

# OpenSSH
# 运行后，要求用户提供密钥文件名
# 然后在当前目录生成两个密钥文件：id_rsa（私钥）和id_rsa.pub（公钥）
$ ssh-keygen -t rsa -b 4096 -C "[email protected]"

# OpenSSL
# 生成私钥，然后生成公钥
$ openssl genrsa -out private_key.pem 4096
$ openssl rsa -pubout -in private_key.pem -out public_key.pem

ruanyf / proxy.js

Created November 28, 2016 06:41

使用 Proxy 实现观察者模式

	// 实现
	const queuedObservers = new Set();

	const observe = fn => queuedObservers.add(fn);
	const observable = obj => new Proxy(obj, {set});

	function set(target, key, value, receiver) {
	const result = Reflect.set(target, key, value, receiver);
	queuedObservers.forEach(observer => observer());
	return result;

Created January 19, 2017 10:47

map vs. flatMap

	const map = (array, func) => (
	array.map(func)
	);

	const flatMap = (array, func) => (
	array.reduce((result, element) => (
	result.concat(func(element))
	), [])
	);

ruanyf / default-parameter-scope.js

Created January 20, 2017 07:03

默认参数的作用域

	// 情况一
	let str = 'outer';

	function foo(x = () => str) {
	let str = 'inner';
	console.log(x()); // outer
	}

	foo();

ruanyf / default-parameter-by-express.js

Created January 20, 2017 09:21

默认参数不是传值调用

	let x = 99;

	function foo(p = x + 1) {
	console.log(p);
	}

	foo() // 100

	x = 100;
	foo() // 101
