Episode 114 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Simon Brand from Codeplay Software to talk about building C++ debuggers and the hardware and C++ firmware of a custom keyboard.

CppCast Episode 114: Building Debuggers and Keyboards with Simon Brand

About the interviewee:

Simon is a GPGPU toolchain developer at Codeplay Software in Edinburgh. He turns into a metaprogramming fiend every full moon, when he can be found bringing compilers to their knees with template errors and debating undefined behaviour on the C++ Slack channel. He co-organises the Edinburgh C++ user group and contributes to various programming standards bodies.

Outside of programming, he enjoys experimental films, homebrewing, and board games.

Ranges, Coroutines, and React: Early Musings on the Future of Async in C++ -- Eric Niebler

By Eric Niebler | Aug 17, 2017 03:56 PM | Tags: intermediate experimental c++20

Eric Niebler shares his thoughts about the interaction of ranges and co-routines in his recent blog post.

Ranges, Coroutines, and React: Early Musings on the Future of Async in C++

by Eric Niebler

From the article:

Another way to look at this is that synchronous ranges are an example of a pull-based interface: the user extracts elements from the range and processes them one at a time. Asynchronous ranges, on the other hand, represent more of a push-based model: things happen when data shows up, whenever that may be. This is akin to the reactive style of programming.

By using ranges and coroutines together, we unify push and pull based idioms into a consistent, functional style of programming. And that’s going to be important, I think.

Your own error condition--Andrzej Krzemieński

The series continues.

Your own error condition

by Andrzej Krzemieński

From the article:

In the previous post we have seen how you can create your own error-code enumeration for representing different reasons for failure in your component, and how you can store them and convey them type erased via std::error_code. In this post we will see how you can inspect an error situation encoded in std::error_code, and how you can build useful queries about error conditions.

C++17 Features And STL Fixes In VS 2017 15.3--Stephan T. Lavavej

It's always getting better!

C++17 Features And STL Fixes In VS 2017 15.3

by Stephan T. Lavavej

From the article:

Visual Studio 2017’s first toolset update, version 15.3, is currently in preview and will be released in its final form very soon. (The toolset consists of the compiler, linker, and libraries. After VS 2017 RTM, the 15.1 and 15.2 updates improved the IDE. The 15.3 update improves both the IDE and the toolset. In general, you should expect the IDE to be updated at a higher frequency than the toolset.)

Video: C++ Concepts TS and Request for Input -- everythingcpp

By rwdougla | Aug 15, 2017 07:09 AM | Tags: c++20

This video teaches the Concepts syntax and motivation, with a request for viewers to try it out for themselves, to submit back their usage, to help guide a paper for the upcoming Albuquerque meeting.

C++ Concepts Intro: Need Your Input

by everythingcpp

From the article:

C++20 is slated to add most of the contents of the Concepts Technical Specification. Concerns about teach/learn-ability and usage preferences has kept some features from going in. This video covers introductory material on Concepts in C++ as it is in the technical specification. Afterward, I would like to hear from you!

CppCon 2016: A modern database interface for C++--Erik Smith

By Adrien Hamelin | Aug 14, 2017 02:44 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:

A modern database interface for C++

by Erik Smith

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

C++ has historically had many options for database connectivity but has lacked a standard interface that other languages, such as Java, have had for a long time. This talk will present a standards grade interface along with experience with a reference implementation that includes support for at least 6 databases. A key aspect of the design is to show how modern C++ features can be used to achieve a high degree of both efficiency and ease-of-use. Specific features to be covered will include type conversion, connection pooling, I/O binding for scalars and arrays, row sets, direct/polymorphic interfaces, policy based design, the driver interface, and details on the implementation. Forward looking standards proposals, such as ranges and variants, will also be included in the discussion.
