Things to remember when compiling/linking C/C++ software

Include Paths

On the compilation phase, you will usually need to specify the different include paths so that the interfaces (.h, .hpp) which define structs, classes, constans, and functions can be found.

With gcc and llvm include paths are passed with -I/path/to/includes, you can pass as many -I as you need.

In Windows, cl.exe takes include paths with the following syntax: /I"c:\path\to\includes\ you can also pass as many as you need.

Here are several different ways to test a TCP port without telnet.

BASH (man page)

$ cat < /dev/tcp/127.0.0.1/22
SSH-2.0-OpenSSH_5.3
^C

$ cat &lt; /dev/tcp/127.0.0.1/23

	#!/bin/bash

	set -e

	GENTOO_RELEASES_URL=http://distfiles.gentoo.org/releases

	GENTOO_ARCH=amd64
	GENTOO_VARIANT=amd64

	TARGET_DISK=/dev/sda

	# CentOS 7 Template Prep
	# Taken from here:
	# https://community.spiceworks.com/how_to/151558-create-a-rhel-centos-6-7-template-for-vmware-vsphere

	# Update everything but skip broken
	yum update --skip-broken -y

	# Stop logging services
	/sbin/service rsyslog stop
	/sbin/service auditd stop

	configure
	delete system name-server
	set system name-server 127.0.0.1

	Since you are getting an IP on your WAN address via DHCP, you'll need to tell the dhcp-client not to add the ISP DNS servers to /etc/resolv.conf.
	set interfaces ethernet eth0 dhcp-options name-server no-update

	By default, dnsmasq will send queries to any of the upstream servers it knows about and tries to favour servers that are known to be up. If you want to query the servers in order instead, then add the following:
	set service dns forwarding options strict-order

	<!-- put this to IDEA keymaps config folder. For v13 it is <userdir>\.IntelliJIdea13\config\keymaps\ -->
	<?xml version="1.0" encoding="UTF-8"?>
	<keymap version="1" name="Mac OS X 10.5+ Windows Ctrl" parent="Mac OS X 10.5+">
	<action id="$Copy">
	<keyboard-shortcut first-keystroke="meta C" />
	<keyboard-shortcut first-keystroke="meta INSERT" />
	<keyboard-shortcut first-keystroke="control C" />
	<keyboard-shortcut first-keystroke="control INSERT" />
	</action>
	<action id="$Cut">

	Just three simple steps:

	docker login --username username --password password
	docker tag my-image username/my-repo
	docker push username/my-repo

	#include <cmath>
	#include <cstdio>
	#include <vector>
	#include <iostream>
	#include <algorithm>
	using namespace std;

	vector<int> get_scores()
	{
	vector<int> ret(3);

	When installing from the RailsInstaller (or any place that causes this issue)
	you might receive an SSL error when trying to update or install gems

	Perform the following steps to update the gems system

	gem source -r https://rubygems.org/
	gem source -a http://rubygems.org/
	gem update --system

	gem install rails -v 4.2.3
