Disable vim automatic visual mode on mouse select

issue: :set mouse-=a
add to ~/.vimrc: set mouse-=a

my ~/.vimrc for preserving global defaults and only changing one option:

source $VIMRUNTIME/defaults.vim
set mouse-=a

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

Below are the steps required to flash a NextThingCo CHIP or PocketCHIP from the command line, as of November 2018. The web flasher no longer works, and there are numerous errors when flashing from the command line, mostly due to broken dependencies. The following method works for flashing a CHIP as of November 2018:

Note: Flashing must be done on Linux. Tested on Ubuntu and Rasparian. Mac OS seems to not work.

1. Download and unpack the CHIP-SDK.zip from one of the following:

• https://archive.org/details/C.h.i.p.FlashCollection
• https://github.com/NextThingCo/CHIP-SDK
• https://github.com/Project-chip-crumbs/CHIP-SDK

2. Download and unpack CHIP-tools.zip from one of the following:
