By Marco Arena | Aug 3, 2017 12:24 AM | Tags: community

I am very happy to announce we published all the videos of the Italian C++ Conference 2017:

C++ executors to enable heterogeneous computing in tomorrow's C++ today (Michael Wong)

Quicker Sorting (Dietmar Kühl)

Monads for C++ (Bartosz Milewski)

Functional C++ for Fun and Profit (Phil Nash)

 

The second track is in Italian:

An overly simple C++ idiomatic pattern language for message-based product families (Carlo Pescio)

Lambda out: a simple pattern for generic output (Davide Di Gennaro)

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

By Adrien Hamelin | Aug 2, 2017 01:48 PM | Tags: 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:

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.

(Not Really So) New Niche for C++: Browser!? -- No Bugs Hare

By Felix Petriconi | Aug 1, 2017 11:33 PM | Tags: intermediate

In this article "No Bugs" Hare outlines the possibility to run C++ code in the major four web browsers.

(Not Really So) New Niche for C++: Browser!?

by "No Bugs" Hare

From the article:

For quite a long while, C++ had been losing popularity; for example, as reported in [Widman16], in 2016 it got 7% less of the listings on Dice.com compared with a year earlier; and according to [TIOBE17], from the C++ Golden Age in 2004 till 2017, the C++ share fell from ~17% to a measly 6%.

As all of us (as in, ‘hardcore C++ fans’) know , this has nothing to do with the deficiencies of C++; rather it is related to an observation that the time of downloadable clients (which was one of the main C++ strongholds) has changed into the time of browser-based clients – and all the attempts to get C++ onto browsers were sooo ugly (ActiveX, anyone?) that this didn’t really leave a chance to use C++ there.

Well, it seems that this tendency is already in the process of being reverted:

C++ can already run on all four major browsers – and moreover, it has several all-important advantages over JavaScript, too.
And this – not too surprisingly – is what this article is all about.

Trip report: Evolution Working Group at the Summer ISO C++ standards meeting Toronto--Andrew Pardoe

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.

C++17: Structured Bindings--Marc Gregoire

It is coming!

C++17: Structured Bindings

by Marc Gregoire

From the article:

This is a first post in a series of short articles on new C++17 features. These articles will not contain all little details of the new features being presented, but they give you an idea about what new functionality has been added to C++17.

CppCon 2016: Iterator Haiku--Casey Carter

By Adrien Hamelin | Jul 31, 2017 12:10 PM | Tags: experimental efficiency

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:

Iterator Haiku

by Casey Carter

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Iterator Haiku: How five iterator categories blossomed into seven, and Sentinels trimmed them back to five again. Recently proposed changes to the ranges TS distill its seven iterator categories back to five without sacrificing any expressive power. Removing operations that are extraneous in the Sentinel world eliminates a potential source of programming errors.

itCppCon17: C++ executors to enable heterogeneous computing in tomorrow's C++ today--Michael Wong

Videos of the Italian C++ Conference 2017 are popping up. Here is the keynote:

C++ executors to enable heterogeneous computing in tomorrow's C++ today

by Michael Wong

Slides

Summary of the talk:

For a long time, C++ has been outpaced by other models such as CUDA, OpenMP, OpenCL, HSA, which has offered Heterogeneous computing capability to enable dispatch to GPU, DSP, FPGA or other accelerators.
SG14 is an ISO C++ SG that works on low-latency, in the areas of Games, Financial, Embedded programming. One of their mandate is support of heterogeneous in Native C++, without having to drop to some other model as is needed today.
This talk will describe the first and possibly the most important step towards supporting heterogeneous computing with a description of C++ executors, an interface between concurrency constructs, and the agents/resources, one of which can be a GPU core, or a SIMD unit.  I have led a small group of experts from Google, Nvidia, Codeplay, and NASDAQ, to define a specification to enable separation of concerns in defining where, when, and how execution is done in service of the constructs in existing C++ standard library, Concurrency, Parallelism, Transactional Memory, and Networking TS.
This talk will help you understand these TSes which currently only works on CPUs and how they will tie together in future to enable execution on accelerators based on C++ models we already have today such as SYCL, HPX, Kokkos, and Raja. This will enable native C++ to be usable on machine learning algorithms on future self-driving cars, or medical devices.

CppCast Episode 111: Toronto Trip Report with Patrice Roy

By robwirving | Jul 28, 2017 07:02 AM | Tags: None

Episode 111 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Patrice Roy to talk about the changes made to the C++20 Draft at the Toronto C++ Standards Committee Meeting.

CppCast Episode 111: Toronto Trip Report with Patrice Roy

by Rob Irving and Jason Turner

About the interviewee:

Patrice Roy has been playing with C++, either professionally, for pleasure or (most of the time) both for over 20 years. After a few years doing R&D and working on military flight simulators, he moved on to academics and has been teaching computer science since 1998. Since 2005, he’s been involved more specifically in helping graduate students and professionals from the fields of real-time systems and game programming develop the skills they need to face today’s challenges. The rapid evolution of C++ in recent years has made his job even more enjoyable.

He’s been a participating member in the ISO C++ Standards Committee since late 2014 and has been involved with the ISO Programming Language Vulnerabilities since late 2015. He has five kids, and his wife ensures their house is home to a continuously changing number of cats, dogs and other animals.
