Calendrical C++: std::chrono, History, Mathematics and the Computus

<p>Our job as programmers is to solve real-world problems with appropriate abstractions. The real world is messy, and few things are messier than dealing with calendars. It has been claimed -- without too much exaggeration -- that most mathematical progress before the 1600s was driven by trying to figure out when Easter falls.</p> <p>This talk combines C++, history, and the process of finding abstractions for this interesting and simplification-resistant problem. Attendees will learn plenty about the proper usage of std::chrono constructs, gain an insight into why calendars are so complex and how to find the right ways to express things clearly, and encounter a plethora of historical goodies along the way.</p> <p>If you need a break from thinking about the (somewhat self-imposed) problems of cutting-edge C++, this is the talk for you: there are only real-world complications here. I've been down this rabbit-hole for months; join me for an exploration of what I've found.</p>

Ben Deane

<p>Ben has been programming in C++ for this whole millennium. He spent just over 20 years in the games industry working for companies like EA and Blizzard; many of the games he worked on used to be fondly remembered but now he’s accepted that they are probably mostly forgotten. After getting more interested in modern C++, in the teens he started giving internal company talks and then talks at various conferences, spreading ideas about types, algorithms and declarative and functional techniques.</p> <p>In 2018 he left the games industry and worked in finance for a short spell, writing high-frequency trading platforms using the most modern C++ that compilers could support. Now he is a Principal Software Engineer at Intel where he puts monads inside your CPU.</p>
