Cppcon: Instructor Interview: Phil Nash / Accelerated Test Driven Design

By Adrien Hamelin | Sep 1, 2020 11:17 AM | Tags: community

Another interesting interview.

Instructor Interview: Phil Nash / Accelerated Test Driven Design

Summary of the video:

In this week’s instructor interview, Kevin Carpenter welcomes Phil Nash for a discussion of his CppCon Academy class, Accelerated TDD: For More Productive C++ . Phil shares the origin story of Catch, the popular testing framework that he authored to support better testing in C++. Kevin has taken a previous CppCon Academy class on testing with Phil. Phil explains that he focuses less on what TDD is (which can be explained in five minutes using one slide) and more on how to apply and get the benefits of TDD in real-world code bases.

CppCon 2019: std::midpoint? How Hard Could it Be?--Marshall Clow

This year, CppCon 2020 is going virtual. The dates are still the same – September 14-18 – and we are aiming for the CppCon live event to have pretty much everything you’re familiar with at CppCon except moved online: multiple tracks including “back to basics” and a new “embedded” track; live speaker Q&A; live talk time zones friendly to Americas and EMEA (and we’re going to try to arrange around-the-clock recorded repeats in all time zones, where speakers who are available can be available for live Q&A in their repeated talks too, and we’ll do that if it’s possible – but we’re still working on it!); virtual tables where you can interact face-to-face online with other attendees just like at the physical event; virtual exhibitor spaces where you can meet the folks on your favorite product’s teams to ask them question face-to-face; pre- and post-conference classes; and even the CppCon house band playing live before every plenary session. All talk recordings will be freely available as usual on YouTube a month or two after the event, but everything else above will be available only live during CppCon week.

To whet your appetite for this year’s conference, here’s another of the top-rated talks from last year. Enjoy – and register today for CppCon 2020 – all the spirit and flavor of CppCon, this year all virtual and online!

std::midpoint? How Hard Could it Be?

by Marshall Clow

Summary of the talk:

The standards committee adopted "P0811: Well-behaved interpolation for numbers and pointers" for C++20.
It includes a new library call `std::midpoint`.
The paper says "The simple problem of computing a value between two other values is surprisingly subtle in general."

In this talk, I will explore this simple call, provide a history of the development in libc++, and show some of the pitfalls.
Undefined behavior will rear its ugly head, along with numeric representations, and the arcane C promotion rules.

Along the way, we'll talk about testing, and why writing extensive tests helps everyone.

Path Tracing Three Ways: A Study of C++ Style

by Matt Godbolt

Summary of the talk:

C++ is a multi-paradigm language allowing us as developers to pick and choose among a variety of styles: procedural, functional, object oriented, hybrids, and more. How does the style of programming we choose affect code clarity, testability, ease of changes, compile time and run-time performance?

In this talk Matt will show a toy path tracer project (a form of ray tracer) implemented in three different styles: traditional object oriented, functional, and data-oriented design. He'll then compare and contrast his experiences developing in each case, showing how often the compiler is able to reduce each style to similar performing code. There's certain to be some surprises - and of course some Compiler Explorer usage!

Speed Is Found In The Minds of People

by Andrei Alexandrescu

Summary of the talk:

In all likelihood, sorting is one of the most researched classes of algorithms. It is a fundamental task in Computer Science, both on its own and as a step in other algorithms. Efficient algorithms for sorting and searching are now taught in core undergraduate classes. Are they at their best, or is there more blood to squeeze from that stone? This talk will explore a few less known – but more allegro! – variants of classic sorting algorithms. And as they say, the road matters more than the destination. Along the way, we'll encounter many wondrous surprises and we'll learn how to cope with the puzzling behavior of modern complex architectures.
