Oral History of Bjarne Stroustrup

About the interview:

In a substantial interview with Paul McJones, Bjarne Stroustrup discusses his youth, his education at the Aarhus University and the University of Cambridge, and his career at AT&T Bell Laboratories, Texas A&M University, and Morgan Stanley. Also covered are his early experience with a variety of programming languages including Simula and BCPL. Finally, the interview focuses on his work on C++ and its predecessor C with Classes, including his goal of combining good abstraction mechanisms with direct access to the hardware. Specific language features discussed include value semantics, templates, concepts, the Standard Template Library, and highlights of the C++11 and C++14 standards.

CppCon 2014 Pragmatic Type Erasure: Solving OOP Problems w/ Elegant Design Pattern--Zach Laine

By Adrien Hamelin | Apr 12, 2015 09:47 AM | Tags: performance efficiency

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:

Pragmatic Type Erasure: Solving OOP Problems w/ Elegant Design Pattern

by Zach Laine

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

There are numerous, serious OOP design problems that we have all encountered in production code. These include, among others: - object lifetime/ownership - how to make classes from different class hierarchies conform to a common interface - writing classes that can present multiple interfaces - separating interface and implementation - how to write virtual functions so that subclasses override them properly - the virtual inheritance "diamond of death"

Proper use of type erasure can mitigate, or outright eliminate, these and other problems, without sacrificing performance.

This talk will cover the OOP design problems above and more, and will cover hand-rolled and library-based type erasure approaches that solve those problems. Performance metrics will be provided for the different approaches, and source code will be available after the talk.

CppCon 2014 Embind and Emscripten: Blending C++11, JavaScript, and the Web Browser--Chad Austin

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:

Embind and Emscripten: Blending C++11, JavaScript, and the Web Browser

by Chad Austin

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Emscripten compiles C or C++ source code into JavaScript so it can run in a web browser. Emscripten is commonly used to port games to the web with no download or plugin required.

Embind is a C++11 binding library that makes it easy to expose libraries written in C++ to JavaScript. This allows JavaScript applications to take advantage of existing bodies of C++ code. In addition, C++ compiled into the asm.js subset of JavaScript is often faster than hand-written JavaScript, so Embind makes it convenient to accelerate JavaScript applications by writing high-performance functionality in C++.

With several motivating examples, this lecture will cover the design of embind, how variadic templates and constexpr facilitate interesting optimizations, and how embind minimizes its impact on the size of the generated JavaScript.

CppCast Episode 7: Quick Game Development with Vittorio Romeo -- Rob Irving

Episode 7 of CppCast the only podcast by C++ developers for C++ developers. In this episode Vittorio Romeo joins Rob Irving to talk about making simple games with C++ using libraries like SFML, SDL and Cinder.

CppCast Episode 7: Quick Game Development with Vittorio Romeo

by Rob Irving

About the interviewee:

Vittorio Romeo is an undergraduate Computer Science student at "Università degli Studi di Messina". Since childhood he has always been interested in programming, and learned to develop applications and games as an autodidact. After discovering C++ a few years ago, Vittorio became extremely passionate about its evolution and its community. He currently works on open-source general-purpose C++14 libraries and develops free open-source games. Vittorio also loves teaching: he manages a well-received C++11/C++14 video tutorial series and he talked about game development in C++ at CppCon 2014. When he's not in front of a computer, Vittorio enjoys fitness activities (weightlifting, swimming, running) and reading.

JetBrains - ReSharper C++ 1.0 released

By Felix Petriconi | Apr 10, 2015 12:01 AM | Tags: None

JetBrains just released their ReSharper for C++ in version 1.0, after a year of an open beta program.

ReSharper for C++

From the website:

ReSharper C++ makes Microsoft Visual Studio a much better IDE with refactorings, navigation, code inspections, quick-fixes, code generation and more productivity features for C++ development.

ReSharper C++ extends Visual Studio with over 60 C++ code inspections that are displayed instantly, as you type.
For many of these inspections, ReSharper C++ provides quick-fixes (light bulbs) to improve code in one way or another.

Call for Submission

From the invitation:

CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community and so we invite you to present.

CppCon 2014 Introduction to C++ AMP (GPGPU Computing)--Marc Gregoire

Introduction to C++ AMP (GPGPU Computing)

by Marc Gregoire

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Meet C++ AMP (Accelerated Massive Parallelism), an abstraction layer on top of accelerators such as GPUs. In its current version it allows you to run code on any DX11 GPU, independent of the vendor, and it will even distribute workload across GPUs of different vendors simultaneously. C++ AMP was originally designed by Microsoft but is now an open standard. C++ AMP can deliver orders of magnitude performance increase with certain algorithms by utilizing the GPU to perform mathematical calculations. This talk will give a high level overview of what C++ AMP is and what it can do for you. It is time to start taking advantage of the computing power of GPUs!
