CppCon 2016: Asynchronous IO with Boost.Asio--Michael Caisse

Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:

Asynchronous IO with Boost.Asio

by Michael Caisse

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Reactive systems are found everywhere. The temptation to implement them with legions of waiting threads can be strong; however, the result is nearly always disappointing. The Boost.Asio library provides a framework to handle asynchronous resources with specific classes directed toward networking, serial port I/O, timers and more. In this session we will introduce Asio and some best practices while implementing a simple TCP client and server.

Asio has been submitted to the C++ Standards Committee for inclusion and can be found in the Boost library collection or as a stand-alone version. Come and learn a better way to implement reactive systems with the Asynchronous I/O library.

The program for CppCon 2017 is now published!

CppCon is the annual conference for the C++ community: five days packed with over 100 talks, as well as inspiring keynotes, panel discussions, hallway chats, fun evening events and much more. CppCon is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer community and promote the understanding and use of modern, standard C++ on all compilers and platforms.

CppCon 2016: The Blaze High Performance Math Library--Klaus Iglberger

The Blaze High Performance Math Library

by Klaus Iglberger

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

In this presentation we introduce the Blaze C++ math library, a hot contender for the linear algebra performance throne. Blaze is an open-source, high-performance library for dense and sparse arithmetic. It combines elegance and ease of use with HPC-grade performance, making it one of the most intuitive and at the same time fastest C++ math libraries available.

We demonstrate its basic linear algebra functionality by means of several BLAS level 1 to 3 operations and explain why Blaze outperforms even well established linear algebra libraries. Additionally, we present some advanced features that enable users to adapt Blaze to special circumstances: custom data structures, custom operations, and the customizable error reporting mechanism.

Trip Report: C++ Standards Meeting in Toronto, July 2017

by Botond Ballo

From the article:

A couple of weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Toronto, Canada (which, incidentally, is where I’m based). This was the second committee meeting in 2017; you can find my reports on previous meetings here (November 2016, Issaquah) and here (February 2017, Kona). These reports, particularly the Kona one, provide useful context for this post.

CppCon 2016: Examining applications that do not terminate on std::bad_alloc--Sergey Zubkov

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:

Examining applications that do not terminate on std::bad_alloc

by Sergey Zubkov

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

System memory holds a special place in the hierarchy of program resources; its availability is the implied precondition for many innocuous lines of code, from std::string::substr() to passing std::function<> by value. The ability to always create another object is ingrained in the OOP mindset so much that it is often said that immediate termination is the cleanest way to handle memory allocation failures in most situations. Nevertheless, C++, when consistently applying RAII, makes it possible to treat memory allocation exactly as any other resource acquisition.

To what degree do actual applications take advantage of that possibility and what responses to allocation failures are there in the wild? This presentation will examine over 300 open source projects that incorporate explicit handling for std::bad_alloc, examine the causes (it’s not always “out of memory”), response strategies (it’s more than just rollback), and related practical considerations.

From the article:

The Summer 2017 ISO C++ standards meeting was held in July 10-15 at the University of Toronto. Many thanks to Google, Codeplay, and IBM for sponsoring the event, as well to folks from Mozilla, Collège Lionel-Groulx, Christie Digital Systems, and Apple for helping to organize. And, of course, we very much appreciate Waterfront International for sponsoring a banquet at the CN Tower.
