Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Network

We need a global docker network in order to communicate between docker-compose setups on different hosts

Step 1: Install and run Consul (as a key-value storage for docker)

https://www.consul.io/intro/getting-started/install.html

Step 2: Edit docker configuration (on each docker host)

Document Conversion

This document outlines some ideas for document conversion on Linux and Mac OS X platforms using command line tools. Distribute documents as plain text using UTF-8 encoding whenever possible. Everyone should embrace the mantra "plain text is beautiful".

Document Metadata

Use file command to obtain basic metadata for most file formats. For image files make sure you have ImageMagick installed, then use identify command to extract image metadata.

R to python data wrangling snippets

The dplyr package in R makes data wrangling significantly easier. The beauty of dplyr is that, by design, the options available are limited. Specifically, a set of key verbs form the core of the package. Using these verbs you can solve a wide range of data problems effectively in a shorter timeframe. Whilse transitioning to Python I have greatly missed the ease with which I can think through and solve problems using dplyr in R. The purpose of this document is to demonstrate how to execute the key dplyr verbs when manipulating data using Python (with the pandas package).

dplyr is organised around six key verbs:
