Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

AWS ELB with Node.js and WebSockets

This assumes that:

You are using Nginx.
You want to accept incoming connections on port 80.
Your Node.js app is listening on port 3000.
You want to be able to connect to your Node.js instance directly as well as via the load balancer.

####1. Create load balancer

When Apple moved to Xcode 5 (and later 6), they changed how you embed the Python.framework in a project: https://developer.apple.com/library/mac/technotes/tn2328/_index.html

This is a basic walkthrough of the process of conversion per that documentation for Xcode 6.

The example used here is the latest version of grahamgilbert's Crypt (at the time of this writeup): https://github.com/grahamgilbert/Crypt/tree/bdd49c849ed07fbc86d8c6f5bc31a525061d5077

Building Blink on OS X

Blink is a SIP client for various platforms. On OS X they only officially distribute the app in the Mac App Store. However the project is GPLed, so you can build it yourself. Here is how:

Download the source

Blink uses the darcs version control system. Download link or brew install darcs using brew package manager.

Open the terminal, and clone the source:
