Raspberry Pi from SD to USB

How to switch over from SD-card to USB-attached device (USB thumbstick, USB enclosed SSD or HDD, etc.) to have more durable storage option.

Steps

Connect USB device to your RPI
Make sure USB device visible by the system

Configure unison for bi-directional sync

1. On client

Create a profile (~/.unison/bidirsync.prf):

# Unison preferences
label = bi-directonal sync with server
root = /home/<user>/git
root = ssh://<user>@<server-name>//home/<user>/sync/git
sshargs = -oIdentityFile=/home/<user>/.ssh/<privkey-name>

Cython example of exposing C-computed arrays in Python without data copies

The goal of this example is to show how an existing C codebase for numerical computing (here c_code.c) can be wrapped in Cython to be exposed in Python.

The meat of the example is that the data is allocated in C, but exposed in Python without a copy using the PyArray_SimpleNewFromData numpy

	sudo echo ""

	package Mojolicious::Plugin::Coro;
	use Mojo::Base 'Mojolicious::Plugin';
	use Coro;
	use Mojo::IOLoop;

	# Wrap application in coroutine and reschedule main coroutine in event loop
	sub register {
	my ($self, $app) = @_;

	my $subscribers = $app->plugins->subscribers('around_dispatch');
