CppCon 2015 C++ in the Audio Industry--Timur Doumler

By Adrien Hamelin | Jun 8, 2016 11:57 AM | Tags: performance advanced

Have you registered for CppCon 2016 in September? Don’t delay – Early Bird registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2015 for you to enjoy. Here is today’s feature:

C++ in the Audio Industry

by Timur Doumler

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Sound is an essential medium for human-computer interaction and vital for applications such as games and music production software. In the audio industry, C++ is the dominating programming language. This talk provides an insight into the patterns and tools that C++ developers in the audio industry rely on. There are interesting lessons to be learned from this domain that can be useful to every C++ developer.

Handling audio in real time presents interesting technical challenges. Techniques also used in other C++ domains have to be combined: real-time multithreading, lock-free programming, efficient DSP, SIMD, and low-latency hardware communication. C++ is the language of choice to tie all these requirements together. Clever leveraging of advanced C++ techniques, template metaprogramming, and the new C++11/14 standard makes these tasks more exciting than ever.

Advanced Unit Testing in C & C++

by Matt Hargett

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

This session goes in-depth into advanced techniques to isolate and unit test C++ classes, especially those in legacy code that isn't easy to change. This builds on the Pragmatic Unit Testing in C++ talk from last year, with live code examples of safe refactorings, injecting mock objects, and potential pitfalls across different platforms and toolchains.

CppCon 2015 Variadic Templates in C++11 / C++14 - An Introduction--Peter Sommerlad

Variadic Templates in C++11 / C++14 - An Introduction

by Peter Sommerlad

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Writing class templates and functions accepting a variable number of arguments has been a burden before C++11. With variadic templates, both class templates with a variable number of arguments as well as functions can be formulated much easier and more type safe way.

Nevertheless, the authoring of variadic templates can be challenging for the uninitiated. Even the interpretation of variadic template code can be a problem, as Olve Maudal's famous pub quiz shows.

This session will build up understanding and the ability to use and author variadic template functions and variadic template classes from easy examples up to more complicated applications such as employing std::forward correctly, std::integer_sequence and other upcoming language features such as a template UDL operator that bridges the gap between string literals and std::integer_sequence.

Understanding pack expansion, sizeof... and other hard to get on first sight issues are my goal. In the end you should have seen guidelines that help you avoid the template instantiation trap from the pub quiz and correct usage of std::forward in your variadic templates.

Episode 58 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Anastasia Kazakova to discuss new features of JetBrains' Clion IDE.

CppCast Episode 58: CLion with Anastasia Kazakova

by Rob Irving and Jason Turner

About the interviewee:

A C/C++ fan since university, Anastasia has been creating real-time *nix-based systems and pushing them to production for 8 years. She has a passion for networking algorithms (especially congestion problems and network management protocols) and embedded programming, and believes in good tooling. Now she is a part of the JetBrains team working as a Product Marketing Manager for CLion, a cross-platform C/C++ IDE.

CppCon 2015 Beyond Sanitizers...--Kostya Serebryany

Beyond Sanitizers...

by Kostya Serebryany

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

At CppCon’2014 we presented the Sanitizers, a family of dynamic testing tools for C++. These tools allow you to find many stability and security bugs in C++ code, but they are only as good as your tests are. In this talk we will show how to improve your tests with guided fuzzing and how to protect your applications in production even if some bugs were not found. Fuzzing, or fuzz testing, is a surprisingly effective technique that allows you to discover new interesting test inputs. Coverage-guided fuzzing uses coverage-like code instrumentation to make fuzzing orders of magnitude more efficient. Taint-guided fuzzing goes even further by using taint tracking techniques. The next line of defense may be incorporated directly into production: the Control Flow Integrity instrumentation allows you to protect your program from corrupted function pointers (including pointers to virtual tables) and separating stack variables from the call stack protects from corrupted return addresses -- both with near-zero overhead. We will concentrate on particular tools implemented in the opensource LLVM toolchain (libFuzzer, DataFlowSanitizer, -fsanitize=cfi,safe_stack), but will also discuss several alternatives.

Lambdas from First Principles: A Whirlwind Tour of C++

by Arthur O'Dwyer

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Lambdas (even those mysterious generic lambdas) are just syntactic sugar atop constructs that are perfectly understandable when approached from the right direction.

We'll start with the implementation of C-style functions, then move to overloading, function templates, non-static member functions, C++11 lambdas, and then demystify C++14 generic ("auto") lambdas. Finally, we'll detour into the implementations of std::function and std::bind to show how they're different from lambdas.

C++ Modules - Spring Update--Gabriel Dos Reis

By Adrien Hamelin | May 27, 2016 02:35 PM | Tags: experimental efficiency

Let's talk about modules!

C++ Modules - Spring Update

by Gabriel Dos Reis

Abstract

“Modules” are a frequently requested and long-awaited feature by C++ programmers. The basic idea is a direct language support for (a) expressing the boundaries and dependencies of program components; (b) isolating source codes from macro vagaries; (c) scaling compile time, especially for large projects, given the ubiquity of “headers-only” template libraries; (d) spur innovation and deployment of semantics-aware developer tools. I will give an overview of the design points, goals, with emphasis on how modules address the four major problems mentioned above. I will also address standardization process and implementation issues

CppCast Episode 57: Runtime Compiled C++ with Doug Binks

By robwirving | May 27, 2016 09:59 AM | Tags: None

Episode 57 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Doug Binks from Enkisoftware to discuss Runtime Compile C++.

CppCast Episode 57: Runtime Compiled C++ with Doug Binks

by Rob Irving and Jason Turner

About the interviewee:

Doug Binks is programming the game Avoyd using Runtime Compiled C++, a technique he co-developed with industry friends; and enkiTS, a lightweight task scheduler.

An experienced game developer, Doug was previously Technical Lead of the Game Architecture Initiative at Intel. He has worked in the games industry in roles ranging from the R&D development manager at Crytek to head of studio at Strangelite, as well as lead programmer. An early interest in games development was sidetracked by a doctorate in Physics at Oxford University, and two post-doctoral posts as an academic researcher in experimental nonlinear pattern formation, specializing in fluid mechanics. His fondest childhood memories are of programming games in assembly on the ZX81.
