Build ORB-SLAM2 on Raspberry Pi 3

Operating system: Ubuntu Mate 16.04

I use Ubuntu Mate instead of the usual Raspbian Jessie mainly because of the gcc version. ORB-SLAM2 requires C++11 support. Raspbian comes with gcc 4.9, which does not handle C++11 by default. That means you have to play around with some compiler flags in ORB-SLAM2's CMakeLists.txt to make it work. In contrast, Ubuntu Mate's gcc 5.4 handles C++11 naturally.

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

Originally, I had included some other solution

	require 'net/http'
	require 'uri'

	#1: Simple POST
	res = Net::HTTP.post_form(URI.parse('http://www.example.com/search.cgi'),
	{'q' => 'ruby', 'max' => '50'})
	puts res.body

	#2: POST with basic authentication
	res = Net::HTTP.post_form(URI.parse('http://jack:[email protected]/todo.cgi'),

	# Backup
	docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

	# Restore
	cat backup.sql \| docker exec -i CONTAINER /usr/bin/mysql -u root --password=root DATABASE
