Greach 2018 awesome list

What is this?

A compilation of all the links to slides and repositories used in workshops or shown by the speakers.

Why

It can be difficult to retrieve all that material on twitter after the conference.

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Squashing Git Commits

The easy and flexible way

This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).

Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.

Switch to the master branch and make sure you are up to date:

git stash用于保存和恢复工作进度

git stash

保存当前的工作进度。会分别对暂存区和工作区的状态进行保存
git stash save "message..."

这条命令实际上是第一条 git stash 命令的完整版

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	import java.lang.invoke.MethodHandles;
	import java.lang.invoke.MethodType;

	public class Hello {
	private static final MethodHandles.Lookup lookup = MethodHandles.lookup();

	public static void main(String[] args) throws Throwable {
	System.out.println("Hello, " + args[0]);
	}

	// ....

	def compilerConfig = new CompilerConfiguration()
	compilerConfig.optimizationOptions.indy = true

	def shell = new GroovyShell(compilerConfig)

	package indy;

	import java.lang.invoke.CallSite;
	import java.lang.invoke.ConstantCallSite;
	import java.lang.invoke.MethodHandle;
	import java.lang.invoke.MethodHandles;
	import java.lang.invoke.MethodType;
	import java.lang.reflect.Constructor;

	import org.objectweb.asm.ClassWriter;

	public class Base64
	{
	public static String encode(byte[] data)
	{
	char[] tbl = {
	'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P',
