Lightning Talks and Lightning Challenge

by Phil Nash

Whilst many of the main conference talks go deep, Lightning Talks are, well, lighter. That doesn’t mean you won’t gain deep insights from some. Many, however, are humorous, entertaining – and often high-energy...

C++ Core Guidelines: Non-Rules and Myths

by Rainer Grimm

Of course, you already know many non-rules and myths to C++. Non-rules and myths which we have to argument against when we use modern C++. The supporting section of the C++ core guidelines addresses the most resistant once but also provides alternatives...

Presenter Interviews: Stephan T. Lavavej

by Kevin Carpenter

In this week’s presenter interview, Kevin Carpenter welcomes Stephan T. Lavavej (STL) for a preview of his upcoming talk, Floating-Point charconv: Making Your Code 10x Faster With C++17’s Final Boss. Stephan discusses achieving a 3x to 10x speed up with charconv in C++17.

Combining Ranges and Smart Output Iterators

by Jonathan Boccara

In our current stage of development of smart output iterators, we have:

• some iterators, such as filter, transform, unzip or demux,
• the possibility to combine them: filter(pred) >>= transform(f) >>= unzip(back_inserter(output1), back_inserter(output2))
• their usage as the output iterator of an STL algorithm:

std::copy(begin(inputs), end(inputs), transform(f) >>= back_inserter(outputs));

What we’re going to work on today is removing the call to std::copy to have a pipeline made of output iterators only. And once we get such a pipeline, we will plug it to ranges, in order to benefit from the expressiveness of both ranges and smart output iterators, in the same expression...

Chaining Output Iterators Into a Pipeline

by Jonathan Boccara

We’ve been over a various set of smart output iterators over the past few weeks. Today we explore how to combine them and create expressive code.

C++ Core Guidelines: Supporting Sections

by Rainer Grimm

Let's recapitulate. In the last two years, I have written about 100 posts to the C++ Core Guidelines. Why? The document answers:  "This document is a set of guidelines for using C++ well. The aim of this document is to help people to use modern C++ effectively.". But my story does not end here. The guidelines have a supporting section...

Presenter Interviews: Kate Gregory

by Kevin Carpenter

In this week’s presenter interview, Kevin Carpenter welcomes back Kate Gregory to preview her upcoming talk Naming is Hard: Let’s Do Better. Kate’s talk will discuss how bad we as C++ developers can be when it comes to naming things and how we could improve.

My C++Now Talk on Smart Output Iterators

by Jonathan Boccara

If you’ve been reading Fluent C++ over the past few weeks, then you’ve noticed that we spent some time on smart output iterators...
