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

Vector Landcover Notes

I would like to be able to make myself one day a vector landcover tileset that looks as good as the ones of the large consumer maps. I tried doing this a bit but so far I have not found a good solution.

The landcover should give you an idea how the nature looks like in a place, whatever that means...

In this gist I would like to write down some notes around the challenges of making a vector landcover tileset.

Installing Python 3.6 on Raspbian

As of January 2018, Raspbian does not yet include the latest Python release, Python 3.6. This means we will have to build it ourselves, and here is how to do it. There is also an ansible role attached that automates it all for you.

1. Install the required build-tools (some might already be installed on your system).

Python list & dict comprehensions translated to JavasScript

Comprehensions are a really useful feature of Python that aren't available in JavaScript (or many languages). These concepts of course can be tranlsated into using map instead. But especially the dictionaries are a bit trickier.

Lists / Arrays

>>> foobar = range(5)
>>> [x + 1 for x in foobar]
[1, 2, 3, 4, 5]
