Mastering Programming - by Kent Beck

From years of watching master programmers, I have observed certain common patterns in their workflows. From years of coaching skilled journeyman programmers, I have observed the absence of those patterns. I have seen what a difference introducing the patterns can make. Here are ways effective programmers get the most out of their precious 3e9 seconds on the planet. The theme here is scaling your brain. The journeyman learns to solve bigger problems by solving more problems at once. The master learns to solve even bigger problems than that by solving fewer problems at once. Part of the wisdom is subdividing so that integrating the separate solutions will be a smaller problem than just solving them together.

Slicing - Take a big project, cut it into thin slices, and rearrange the slices to suit your context. I can always slice projects finer and I can always find new permutations of the slices that meet different needs

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

%% The typical answer for how to eliminate white space in wrapfigure doesn't work for me (I'm using a SIGGRAPH style sheet):
%%     http://tex.stackexchange.com/questions/111393/too-much-space-around-wrap-figure
%% Instead, let's just offset the image.
%% The horizontal white space is \columnsep and the vertical white space is \intextsep.
%% Subtract them from the column width and offset the image accordingly.
%% How to move an image:

So you want to build a mutation testing system

Introduction

There have been a lot mutation testing systems, but very few have them have seen succesfull use in industry.

This document is a set of notes that might be helpful for anyone thinking of implementing a mutation testing system for another language.

It represents some of the things we learnt while creating pitest. The choices made by pitest are not neccessarily the best choices for your system. Some of these choices are appropriate only because of the particular quirks of Java and the JVM, and some of them are simply the first idea that we had.
