The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

ZeroMQ vs Redis

This document is research for the selection of a communication platform for robot-net.

Goal

The purpose of this component is to enable rapid, reliable, and elegant communication between the various nodes of the network, including controllers, sensors, and actuators (robot drivers). It will act as the core of robot-net to create a standardized infrastructure for robot control.

Requirements:

	# taken from http://www.piware.de/2011/01/creating-an-https-server-in-python/
	# generate server.xml with the following command:
	# openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes
	# run as follows:
	# python simple-https-server.py
	# then in your browser, visit:
	# https://localhost:4443

	import BaseHTTPServer, SimpleHTTPServer
	import ssl

	@foo = thread_local global i32 3

	define i32 @main() {
	%1 = load i32* @foo
	ret i32 %1
	}


	// ./x86_64-apple-darwin/llvm/Release+Asserts/bin/llc foo.ll -filetype=obj
	// gcc -o foo foo.o
