Are you wondering how to use the Microsoft Cognitive Services with C++?
Microsoft Cognitive Services C++ SDK
by Sebastiano Galazzo
Introduction:
The project is a wrapper to use Microsoft Cognitive Services in standard C++ as is currently not supported.
The project provides full support to Computer Vision API. A wrapper to gphoto2 will provide the full control digital cameras (DSLR), getting the raw shot and making manipulations with Computer Vision API.
Available camera-ai, a working commandline example to take a picture from the camera conneced by USB and analyze by Cognitive Services.
A lot of people have a better C++ than mine, who wants to contribute is welcomed!

While ReSharper C++ 2018.1 introduced two major new features, debug step filters and includes analyzer, ReSharper C++ 2018.2 is focused on improving its understanding of the C++ language. C++17 and C++20 got some special attention. However, the biggest highlight is the long-awaited support for C++/CLI.
What’s New in ReSharper C++ 2018.2
by Igor Akhmetov
From the article:
This release introduced:
- Initial C++/CLI support
- C++17 features: class template argument deduction, fold expressions, auto non-type template parameters, pack expansions in using declarations, Using declarations with multiple declarators, guaranteed copy elision, and more
- C++20 features: coroutines, designated initialization, and some others
- Integrated spell checking with ReSpeller
- Formatting inspections

Are you using the parallel capacities of the std?
Using C++17 Parallel Algorithms for Better Performance
by Billy O’Neal
From the article:
C++17 added support for parallel algorithms to the standard library, to help programs take advantage of parallel execution for improved performance. MSVC first added experimental support for some algorithms in 15.5, and the experimental tag was removed in 15.7.
The interface described in the standard for the parallel algorithms doesn’t say exactly how a given workload is to be parallelized. In particular, the interface is intended to express parallelism in a general form that works for heterogeneous machines, allowing SIMD parallelism like that exposed by SSE, AVX, or NEON, vector “lanes” like that exposed in GPU programming models, and traditional threaded parallelism.
Our parallel algorithms implementation currently relies entirely on library support, not on special support from the compiler. This means our implementation will work with any tool currently consuming our standard library, not just MSVC’s compiler. In particular, we test that it works with Clang/LLVM and the version of EDG that powers Intellisense...

Metashell provides a compile-time debugger for debugging template instantiations and macro usage.
Metashell 4.0.0 is available
From the website:
Some of the major new features in 4.0.0:
- The template debugger supports the Templight patch already merged into Clang (7.0.0), therefore it does not require custom Clang builds.
- Preprocessor shell support for GCC, MSVC and Boost.Wave
- PDB, the preprocessor debugger (similar to MDB, the template debugger)
- Using different configs in Metashell (for testing the same templates/macros with different compilers)
The full list of changes can be found here.
An online demo can be found at http://metashell.org/about/demo/
Installers can be downloaded from http://metashell.org/getting_metashell/installers#version-400

Using Abseil became easier.
Clang-Tidy Checks for Abseil
by Deanna Garcia and Hugo Gonzalez
From the article:
Abseil wants to help developers avoid common mistakes unique to our collection of libraries. Therefore, we have developed a set of clang-tidy checks for Abseil, allowing you to catch these errors early on before they become bigger problems...

Getting more conforming!
Use the official Boost.Hana with MSVC 2017 Update 8 compiler
by Bat-Ulzii Luvsanbat
From the article:
We would like to share a progress update to our previous announcement regarding enabling Boost.Hana with MSVC compiler. Just as a quick background, Louis Dionne, the Boost.Hana author, and us have jointly agreed to provide a version of Boost.Hana in vcpkg to promote usage of the library among more C++ users from the Visual C++ community. We’ve identified a set of blocking bugs and workarounds and called them out in our previous blog, and stated that as we fix the remaining bugs, we will gradually update the version of Boost.Hana in vcpkg, ultimately removing it and replacing it with master repo. We can conduct this development publicly in vcpkg without hindering new users who take a dependency on the library...

The vcpkg version of Boost.Hana now just points to the official master repo, instead of VC++ Team fork:

SYCL is an open standard developed by the Khronos™ Group that enables developers to write code for heterogeneous systems using standard C++. Developers are looking at how they can accelerate their applications without having to write optimized processor specific code. SYCL is the industry standard for C++ acceleration, giving developers a platform to write high-performance code in standard C++, unlocking the performance of accelerators and specialized processors from companies such as AMD™, Intel™, Renesas™ and Arm®.
Codeplay Announces World's First Fully-Conformant SYCL 1.2.1 Solution
by Codeplay
About the release:
Codeplay's ComputeCpp 1.0 enables SYCL and provides C++ developers with huge benefits:
High Performance Computing: Supercomputers are playing an important role in computationally intensive tasks in the fields of science, finance, and many others to provide complex calculations and simulations. SYCL offers a standard way for HPC developers to write portable, efficient, accelerated code using standard C++ that can be deployed to GPUs, FPGAs and other accelerators
Computer Vision: Complex image processing operations can be accelerated using parallel computing. ComputeCpp and SYCL provide high-level programmability for custom vision processors, enabling additional custom features on top of existing optimized hardware functions
Artificial Intelligence: Linear algebra is increasingly being used in artificial intelligence applications and benefits from parallel architectures. The Eigen linear algebra library, SYCLBLAS and TensorFlow frameworks can be accelerated using ComputeCpp for a wide variety of heterogeneous hardware
