pacific++

About the conference:

The conference will be held at the Sudima Hotel on the 26th and 27th of October 2017, in Christchurch, New Zealand.

 

Advanced C++ for Embedded Systems, Swindon UK 8-12 May 2017

Join us to advance your C++03 skills if you work in an embedded environment.

Advanced C++ for Embedded Systems

About the course:

This course addresses the “fear, uncertainty and doubt” of using full C++. Specifically the course deals with: performance and memory considerations of polymorphic functions, exceptions and templates. In addition, complete coverage of the Standard Library (including the STL) is provided, again addressing the specifics of performance and memory models.

This is a five day course, which reviews C++ in the light of real-time systems, addresses the application of C++ in a real-time/embedded environment, and then focuses on the advanced parts of the language. 50% of the course is spent on practical work and the course includes the use of target hardware.

 

Quick Q: Syntax of final, override, const with trailing return types

By Adrien Hamelin | Apr 24, 2017 12:43 PM | Tags: c++11 basics

Quick A: The signature of the function is first.

Recently on SO:

Syntax of final, override, const with trailing return types

The correct syntax should be:

  • override and final should appear after the member function declaration, which including the trailing return type specification, i.e.
auto debug(ostream& os=cout) const ->ostream& override final;
  • override and final should not be used with the member function definition outside the class definition, so just remove them:
auto Derived::debug(ostream& os) const ->ostream&
{
  os << "dval: " << dval << endl;
  return os;
}

HPX version 1.0 released -- STE||AR Group

By Hartmut Kaiser | Apr 24, 2017 06:01 AM | Tags: performance parallelism heterogeneous computing distributed computing c++17 c++14 c++11

The STE||AR Group has released V1.0 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.0 Released

The newest version of HPX (V1.0) is now available for download! Please see here for the release notes.

HPX exposes an API fully conforming to the concurrency related parts of the C++11/C++14/C++17 standards, extended and applied to distributed and heterogeneous computing, and aligned with the ongoing standardization discussions.

From the announcement:

  • HPX is a general purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++ Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 parallel algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the C++ Concurrency TS, task blocks, data-parallel algorithms, executors, index-based parallel for loops, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g. compute clusters) and for heterogeneous systems (e.g. GPUs).
  • HPX seamlessly enables a new asynchronous C++ Standard Programming Model which tends to improve the parallel efficiency of our applications and helps reduce complexities usually associated with concurrency

 

CppCast Episode 98: Hippomocks and cpp-dependencies with Peter Bindel

By robwirving | Apr 21, 2017 07:26 AM | Tags: None

Episode 98 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Peter Bindels to discuss the Hippomocks mocking library and the cpp-dependencies tool he worked on that was open sourced from TomTom.

CppCast Episode 98: Hippomocks and cpp-dependencies with Peter Bindel

by Rob Irving and Jason Turner

About the interviewee:

Peter Bindels is a C++ software engineer who prides himself on writing code that is easy to use, easy to work with and well-readable to anybody familiar with the language. He's worked for a contractor for a few years and then made the switch to work at Tomtom, where he's been working on various parts of the software chain, last of which was a major cleanup in the navigation code base. In doing so he developed a tool to determine, check and improve dependencies between components, which allows quicker structural insight in complicated systems. He also created HippoMocks in 2008, one of the first full fledged C++ mocking frameworks that is still a relevant choice today. He has given two talks at Meeting C++ 2016 and will be giving his third talk, on Mocking in C++, at CppNow 2017.

Boost 1.64.0 is released

By Adrien Hamelin | Apr 20, 2017 01:06 PM | Tags: community boost

The new boost is out!

Boost 1.64.0 is released

From the article:

New Libraries


Process:
Process library by Klemens D. Morgenstern, that provides cross platorm ways to allows you to:

  • create child processes
  • setup streams for child processes
  • communicate with child processes through streams (synchronously or asynchronously)
  • wait for processes to exit (synchronously or asynchronously)
  • terminate processes

Broken feature:

GitHub #67: "group.wait() does not return".

Updated Libraries

Any:

  • Suppressed false warnings about returning reference to temporary
  • boost::addressof is now used instead of directly taking the address #12615
  • Headers are not included using double quotes any more #12053
  • CI tests now run with address, leak, and undefined sanitizers
  • Added more test

Atomic:

  • Fixed possible incorrect code generation in 64-bit atomic operations on 32-bit x86 with gcc versions older than 4.7 and compatible compilers.

Config:

  • Added BOOST_NO_CXX11_SFINAE_EXPR defect detection.

C++ Jobs and Predictions -- Bartlomiej Filipek

By bfilipek | Apr 19, 2017 12:09 AM | Tags: community

Is C++ job market falling or growing? Since billions of lines of code are already written it's not possible to disappear in a second. So what's the current state and the future?

C++ Jobs and Predictions

by Bartlomiej Filipek

From the article:

... if you like this area you'll be able to find a C++ job anyway. I hope C++20 will add another good reason to stick with C++ and even move from other languages... but we need to wait a few years to see it happening.
