Moving Authy to 1Password

1Password 5.3 for OSX, 5.2 for iOS, and 4.1.0.538 for Windows support OTP. I've been using Authy for a while now, but the fact is, I haven't really been using 2FA for some time. As mentioned by 1Password in a recent blog post, having the OTP generator and password on the same device is very much not 2FA. It's just an expiring OTP, which can help, but let's not kid ourselves too much.

With that out of the way. One of the things that was interesting to me was moving my OTP out of Authy and into 1Password. I like the control I get with 1Password, but I didn't want to have to reset all my OTP right away, that would suck. So, I got to dissecting the Authy Chrome App to see what I could do.

Run the Authy Chrome app and make sure it's unlocked.

Now, enable Developer mode in Chrome. We'll need this to inspect the background application that stores al

%Q, %q, %W, %w, %x, %r, %s, %i

Perl-inspired notation to quote strings: by using % (percent character) and specifying a delimiting character.

Any single non-alpha-numeric character can be used as the delimiter, %[including these], %?or these?, %~or even these things~.

% or %Q

Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

Producers send messages to brokers
Consumers read messages from brokers
Messages are sent to a topic

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Building TensorFlow 1.3.0-rc1 for Raspberry Pi/Ubuntu 16.04: a Step-By-Step Guide

Here you'll learn how to build Tensorflow for the raspberry pi 3 with either the Python API or as a standalone shared library which can be interfaced from the C++ API and eventually as a library which can be used in other languages.

For the C++ library this tutorial will show you how extract tensorflow library and headers to use in any environment you want.

What You Need

First of all, please note that token expiration and revoking are two different things.

Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

	#!/bin/bash

	if [ `id -u` -ne 0 ]; then
	echo "Rippling uninstall must be run by root"
	exit 1
	fi

	sudo launchctl unload /Library/LaunchDaemons/com.rippling.*
	sudo rm -rf /Library/LaunchDaemons/com.rippling.*
	sudo rm -rf /opt/rippling
