It's getting closer.

Qt talks at CppCon 2017

by Giuseppe D'Angelo

From the article:

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

By Adrien Hamelin | Aug 7, 2017 03:24 PM | Tags: performance community

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:

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

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.

The evolution does not stop.

Trip report: Evolution Working Group at the Summer ISO C++ standards meeting (Toronto)

by Andrew Pardoe

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.

CppCon 2016: GDB - A Lot More Than You Knew--Greg Law

GDB - A Lot More Than You Knew

by Greg Law

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

If you’re writing C++ for anything other than Windows, chances are that you occasionally break out GDB. This session presents some of the lesser known features of GDB that can change the way you debug. GDB has come a long way in the last few years and now does so much more than break, print, step and continue. Reversible debugging; Non-Stop Mode; Multi-process Debugging; and Dynamic Printf are but some of its best features, and its built-in Python scripting is particularly powerful. Join Undo co-founder and CEO, Greg Law, as he takes you through a series of demos to show some amazing tricks with GDB and some of its powerful new (and not-so-new) features that you may not have heard of.
