Did you ever use them?

C++ Online Compilers

by Arne Mertz

From the article:

Online compilers can be useful tools to quickly compile a snippet of code without having to install a proper compiler on our computer. They can be especially useful to play with the newest language features, to share code snippets online or to compare different compilers...

corsl - Coroutine support library--Alexander Bessonov

Interesting library

corsl - Coroutine support library

by Alexander Bessonov

From the article:

corsl stands for "Coroutine Support Library" and consists of a number of utility classes and functions that simplify asynchronous programming in Windows. It is inspired by an amazing cppwinrt library, developed by Microsoft.

cppwinrt was created as a language projection for Windows Runtime, which is supported by Windows 8 or later operating systems. It is impossible to use in prior Windows versions.

One of the goals of corsl library was being able to use it under Windows Vista or later operating system...

A self-contained Pool in C++14--Jens Weller

How to do a pool?

A self-contained Pool in C++14

by Jens Weller

From the article:

During C++Now I started writing a small application, that plays around with dlibs face recognition features. More on this later, the program uses the QThreadPool, and some researched showed that calling dlib::get_frontal_face_detector() is a very expensive operation. So I decided to write a thread safe pool to share the face detection object between threads, only loading as many as needed. The main thread owns the pool which owns the detection objects...

Accelerating your C++ on GPU with SYCL -- Simon Brand

A post on writing GPGPU code in C++ using the SYCL standard from the Khronos group.

Accelerating your C++ on GPU with SYCL

By Simon Brand

From the article:

Leveraging the power of graphics cards for compute applications is all the rage right now in fields such as machine learning, computer vision and high-performance computing. Technologies like OpenCL expose this power through a hardware-independent programming model, allowing you to write code which abstracts over different architecture capabilities. The dream of this is “write once, run anywhere”, be it an Intel CPU, AMD discrete GPU, DSP, etc. Unfortunately, for everyday programmers, OpenCL has something of a steep learning curve; a simple Hello World program can be a hundred or so lines of pretty ugly-looking code. However, to ease this pain, the Khronos group have developed a new standard called SYCL, which is a C++ abstraction layer on top of OpenCL. Using SYCL, you can develop these general-purpose GPU (GPGPU) applications in clean, modern C++ without most of the faff associated with OpenCL.

Better C++ / Chicago July 12-14, 2017

Join us for a 3 day training event in Chicago, IL, USA July 12-14, 2017

Better C++ / Chicago

by Jason Turner

About the training:

Through this training you will gain a better understanding of how to write clean, maintainable, and well performing C++ code.

The topics covered apply to all types of C++ development: embedded, system or application development.

Jason's classes are highly interactive and have a limited class size to ensure that everyone has sufficient opportunity to participat

A la carte tickets are available for those wishing to attend only part of the training.

Wednesday: Demystifying C++11 and Beyond

C++11, 14, and 17 added many new features to C++ that have made many question the overhead of using these new features and the complexity they add to the language. We will make an in depth examination of these features to give you confidence in using and deploying modern C++ techniques in your organization.

Thursday: Understanding Object Lifetime in C++

C++ has what very few other languages have: a well defined object life cycle. Understanding this key aspect of the language is critical for writing high quality C++.
We will describe the lifecycle of an object in C++ and work through increasingly complex examples. There will be something for C++ developers of all skill levels to learn.

Friday: C++ Best Practices

On the final day of the course we will cover a series of tangible best practice rules for how to write C++ code that is maintainable and efficient by default.
We will wrap up with a discussion of how to use the tools available to maintain code quality.

C++Now 2017

by Michael Park

From the article:

I just returned from C++Now 2017 in Aspen, CO. This was my second time attending the conference and it was just as amazing as last year. My girlfriend decided to come along this time, since Aspen is such a beautiful place. We flew into Denver, rented a car and took the beautiful 4-hour drive into Aspen. She was very happy ��.
