1. Clone your fork:

git clone git@github.com:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

#!/usr/bin/env python
# Python 2 and 3 compatible.

#This script takes in a PDF and creates two new PDFs. One has the black and 
#white pages and the other has the colour pages. It also takes duplex printing
#into account. So a black and white side which is on the same sheet as a colour
#side will be placed into the colour PDF.

#This is from a script created by Iain Murray. The original comment is below. 
#This version simply has some different defaults and removes the PDFtoPPM.

To remove a submodule you need to:

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

This was tested on a ThinkPad P70 laptop with an Intel integrated graphics and an NVIDIA GPU:

lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GM204GLM [Quadro M3000M] (rev a1)

A reason to use the integrated graphics for display is if installing the NVIDIA drivers causes the display to stop working properly. In my case, Ubuntu would get stuck in a login loop after installing the NVIDIA drivers. This happened regardless if I installed the drivers from the "Additional Drivers" tab in "System Settings" or the ppa:graphics-drivers/ppa in the command-line.

Git submodules best practices

Useful commands

— Clone repository with submodules automatically:

git clone --recursive git@github.com:name/repo.git

— Initialize submodules after regular cloning:

#include <tf/tf.h>
#include <nav_msgs/Odometry.h>
#include <geometry_msgs/Pose2D.h>

ros::Publisher pub_pose_;

void odometryCallback_(const nav_msgs::Odometry::ConstPtr msg) {
    geometry_msgs::Pose2D pose2d;
    pose2d.x = msg->pose.pose.position.x;
    pose2d.y = msg->pose.pose.position.y;
