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

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt
.
As it is not possible to change the ports used for the standalone
authenticator and I already have a nginx running on port 80/443, I opted to use the webroot
method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com
and example.com
).
For this, I placed config files into etc/letsencrypt/configs
, named after <domain>.conf
. The files are simple:
First of all, it just seems like doing anything with Oracle is obnoxiously painful for no good reason. It's the nature of the beast I suppose. cx_oracle is a python module that allows you to connect to an Oracle Database and issue queries, inserts, updates..usual jazz.
Step 1:
sudo apt-get install build-essential unzip python-dev libaio-dev
