extern c: Talking to C Programmers about C++

by Dan Saks

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Most of us have heard this story. We’ve even told it ourselves…

C++ is nearly all of C, plus a whole lot more. Migrating code from C to C++ is pretty easy. Moreover, the migration itself can yield immediate benefits by exposing questionable type conversions that can be sources of latent bugs. After migration, the code performs as well in C++ as in the original C. And now that it’s C++, you have ready access to a wealth of advanced features you can (but don’t have to) use to implement enhancements.

Who wouldn’t want that? Legions of C programmers, apparently.

Despite the success of C++ in numerous application domains, C remains considerably more popular, especially in embedded, automotive, and aerospace applications. In many cases, projects resist C++ because their managers think the risks outweigh the benefits. In other cases, the resistance comes from programmers who persist in believing bad things about C++, even when those things aren’t true.

What can the C++ community do to overcome this resistance? Drawing on lessons from cognitive science, linguistics and psychology, and (of course) computer science, this talk offers suggestions about how to make the case for C++ more persuasive to C programmers.

Practical Performance Practices

by Jason Turner

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

In the past 6 years ChaiScript's performance has been improved by nearly 100x. This was not accomplished by adding a virtual machine or performing dynamic recompilation. Instead, these increases have been accomplished by moving to more simple, cleaner, idiomatic C++ and by following some simple rules. We will outline these concepts with examples for how they both simplified code while improving performance.

Episode 104 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Tony Van Eerd to talk about his recent award winning C++Now talk on Postmodern C++ and his views on lock-free programming.

CppCast Episode 104: Postmodern C++ with Tony Van Eerd

by Rob Irving and Jason Turner

About the interviewee:

Tony Van Eerd has been coding for well over 25 years, and hopefully coding well for some of that. Mostly in graphics/video/film/broadcast (at Inscriber & Adobe), writing low level pixel++, high level UI, threading, and everything else. He now enables painting with light at Christie Digital. He is on the C++ Committee. He is a Ninja and a Jedi.

CppCon 2016: STL Algorithms - why you should use them, and how to write your own--Marshall Clow

STL Algorithms - why you should use them, and how to write your own

by Marshall Clow

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

One of the most powerful features of the C++ standard library is the collection of basic algorithms. Everyone knows about sort and copy, but there are is a lot of powerful capabilities in the other algorithms as well. In this talk, I will explore some of the algorithms in the library, and give a rationale for writing your own, along with examples.

The motivation for writing your own algorithms is that you can create generic building blocks that can be used over and over again in your library or application, and which will allow your to program at a higher level of abstraction. Instead of thinking, "how do I sort this vector", you just call std::sort. The same should apply to the algorithms that are specific to your domain - once you write them.

High Performance Code 201: Hybrid Data Structures

by Chandler Carruth

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Modern programs’ performance characteristics are often dictated by their data. Whether the cache locality of data access, the size of working set, or avoiding costly memory allocation overhead. Unfortunately, the standard C++ library data structures range from adequate to terrible at controlling these aspects, and they don’t provide any of the core mechanisms needed for extremely efficient data structure design.

This talk will present the core concepts of designing high performance data structures in C++. It is based on years of experience in the LLVM compiler as well as several other large code bases. From these principles, the talk will propose a suite of data structures that provide performance without loss of generality or functionality. As much as this talk will present specific data structure designs, its primary intent will be to give an understanding of what makes these structures have greater performance than more naive approaches.

CppCon 2016: Garbage In, Garbage Out: Arguing about Undefined Behavior...--Chandler Carruth

Garbage In, Garbage Out: Arguing about Undefined Behavior...

by Chandler Carruth

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

There has been an overwhelming amount of tension in the programming world over the last year due to something that has become an expletive, a cursed and despised term, both obscene and profane: **undefined behavior**. All too often, this issue and the discussions surrounding it descend into unproductive territory without actually resolving anything.

In this talk, I'm going to try something very bold. I will try to utterly and completely do away with the use of the term "undefined behavior" in these discussions. And I will unquestionably fail. But in the process of failing, I will outline a framework for understanding the actual root issues that the software industry faces here, and try to give constructive and clear paths forward, both for programmers and the programming language.

And, with luck, I will avoid being joined on stage by any unruly nasal demons.
