Raspberry Pi VPN Router

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.

Requirements

Install Raspbian Jessie (2016-05-27-raspbian-jessie.img) to your Pi's sdcard.

Use the Raspberry Pi Configuration tool or sudo raspi-config to:

First, to get a list of the assets for the latest release:

curl -H "Authorization: token YOURGITHUBTOKEN" https://api.github.com/repos/NAME/REPO/releases/latest 
Then in the JSON, look up the url of the asset you want. For example it would look like: "url": "https://api.github.com/repos/NAME/REPO/releases/assets/1275759"

Then you pass this to another curl command to retrieve the actual URL, which is actually a link to an Amazon S3 file.

curl -H "Authorization: token YOURGITHUBTOKEN" -H "Accept:application/octet-stream" -i https://api.github.com/repos/NAME/REPO/releases/assets/1275759
The URL will be in the "location" field of the HTTP response, and then use curl to get the file like this:

Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

1. Gemfile

gem 'browserify-rails', '1.5.0' # until fix: https://github.com/browserify-rails/browserify-rails/issues/101
gem 'react-rails'

Browserify-rails allows to use browserify within assets pipeline. React-rails is here only to allow to use #react_component (and thus, prerendering).

Note that jquery-rails can be removed from Gemfile, the npm version of jquery and jquery-ujs will be used instead.
