Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

Environment variables in Jekyll templates

This is one way to pass some data (API tokens, etc.) to your Jekyll templates without putting it in your _config.yml file (which is likely to be committed in your GitHub repository).

Copy the environment_variables.rb plugin to your _plugins folder, and add any environment variable you wish to have available on the site.config object.

In a Liquid template, that information will be available through the site object. For example, _layouts/default.html could contain:

Testing _subscript and ^superscript

Testing _{subscript _{subscript level 2}}

Testing ^{superscript ^{superscript level 2}}

OAUTH2

The Problem

I’m a web app that wants to allow other web apps access to my users’ information, but I want to ensure that the user says it’s ok.

The Solution

I can’t trust the other web apps, so I must interact with my users directly. I’ll let them know that the other app is trying to get their info, and ask whether they want to grant that permission. Oauth defines a way to initiate that permission verification from the other app’s site so that the user experience is smooth. If the user grants permission, I issue an AuthToken to the other app which it can use to make requests for that user's info.

Note on encryption

Oauth2 has nothing to do with encryption -- it relies upon SSL to keep things (like the client app’s shared_secret) secure.

Compiling v8 and Hello, World Example on Mac OSX Mavericks (10.9.4)

by Keith Rosenberg (netpoetica)

Note: do this in some sort of project/ directory that makes sense. depot_tools are going to need to be in your path, so you may want to install them somewhere you are comfortable with.

1) Get the v8 source

git clone https://github.com/v8/v8.git

2) Install depot tools

Operational PGP

This is a guide on how to email securely.

There are many guides on how to install and use PGP to encrypt email. This is not one of them. This is a guide on secure communication using email with PGP encryption. If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.
