Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

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

Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

• To enable systemd under WSL we require a tool called systemd-genie

• Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

Switching from XML to xml2

Rationale

The R package XML for parsing and manipulation of XML documents in R is not actively maintained anymore, but used by many:

The R package xml2 is an actively maintained, more recent alternative.

This file documents useful resources and steps for moving from XML to xml2.

# Load the raw training data and replace missing values with NA
training.data.raw <- read.csv('train.csv',header=T,na.strings=c(""))

# Output the number of missing values for each column
sapply(training.data.raw,function(x) sum(is.na(x)))

# Quick check for how many different values for each feature
sapply(training.data.raw, function(x) length(unique(x)))

# A visual way to check for missing data
