These are instructions for setting up git to authenticate with GitHub when you have 2-factor authentication set up. This authentication should be inherited by any GUI client you are using. These are intentionally brief instructions, with links to more detail in the appropriate places.

Download and install the git command-line client (if required).

Open the git bash window and introduce yourself to git (if required):

git config --global user.name 'Firstname Lastname'
git config --global user.email '[email protected]'

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

Kafka Topics

List existing topics

bin/kafka-topics.sh --zookeeper localhost:2181 --list

Describe a topic

bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic mytopic

Purge a topic

bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic mytopic --config retention.ms=1000

... wait a minute ...

Building

go build -o goencrypt main.go

Generating Keys

So you want to generate ISO8601 formatted timestamps in Ruby, but need resolution finer than a second?

First, make sure to require 'time' in order to get ISO8601 formatting. But that gets you this:

2.1.0 :001 > require 'time'
 => true 
2.1.0 :002 > Time.now.utc.iso8601
 => "2015-11-12T04:46:43Z"

	import (
	"log"

	consulapi "github.com/hashicorp/consul/api"

	// Lock stores data for a consul lock
	type Lock struct {

	package main

	import (
	"fmt"
	"reflect"
	)

	// Name of the struct tag used in examples
	const tagName = "validate"
