Announcing diversity tickets for Meeting C++ 2016
Shortly before CppCon started, I was able to offer diversity tickets for Meeting C++:

Concepts Lite vs enable_if--Andrzej KrzemieĊski
Concepts Lite vs enable_if
by Andrzej Krzemieński
From the article:
This post contains quite advanced material. I assume you are already familiar with Concepts Lite. For an overview of what Concepts Lite is, I recommend this proposal. Also, I have found this blog very useful regarding the details of and issues with concepts’ mechanics. One could look at Concepts Lite as three features:
- A superior alternative to enable_if (or overload hiding).
- The subsumption relation that enables the additional control of partial ordering in the overload resolution process.
- A convenient tool for building compile-time predicates that check for valid types and expressions.
In this post I will only focus on the first feature, and try to answer the question, “what do we need Concepts Lite for, given that we already have std::enable_if (and SFINAE)?”
CppCon 2015 Work Stealing--Pablo Halpern
Have you registered for CppCon 2016 in September? Don’t delay – Late registration is open now.
While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2015 for you to enjoy. Here is today’s feature:
Work Stealing
by Pablo Halpern
Summary of the talk:
If you've used a C++ parallel-programming system in the last decade, you've probably run across the term "work stealing." Work stealing is a scheduling strategy that automatically balances a parallel workload among available CPUs in a multi-core computer, using computation resources with theoretical utilization that is nearly optimal. Modern C++ parallel template libraries such as Intel(R)'s TBB or Microsoft*'s PPL and language extensions such as Intel(R) Cilk(tm) Plus or OpenMP tasks are implemented using work-stealing runtime libraries.
Most C++ programmers pride themselves on understanding how their programs execute on the underlying machine. Yet, when it comes to parallel programming, many programmers mistakenly believe that if you understand threads, then you understand parallel runtime libraries. In this talk, we'll investigate how work-stealing applies to the semantics of a parallel C++ program. We'll look at the theoretical underpinnings of work-stealing, now it achieves near optimal machine utilization, and a bit about how it's implemented. In the process, we'll discover some pit-falls and how to avoid them. You should leave this talk with a deeper appreciation of how parallel software runs on real systems.
Previous experience with parallel programming is helpful but not required. A medium level of expertise in C++ is assumed.
Exploring std::string--Shahar Mike
The insides are revealed:
Exploring std::string
by Shahar Mike
From the article:
Every C++ developer knows that
std::stringrepresents a sequence of characters in memory. It manages its own memory, and is very intuitive to use. Today we’ll explorestd::stringas defined by the C++ Standard, and also by looking at 4 major implementations.
Starting With the Poco Libraries--Arne Mertz
Here is a beginner's guide:

From the article:
Recently I started to use the web server functionality of Poco. Today I’ll describe my first experiences with the library.
CppCon 2015 3D Face Tracking and Reconstruction using Modern C++--Patrik Huber
Have you registered for CppCon 2016 in September? Don’t delay – Late registration is open now.
While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2015 for you to enjoy. Here is today’s feature:
3D Face Tracking and Reconstruction using Modern C++
by Patrik Huber
Summary of the talk:
In this talk, I will present my work in computer vision, namely landmark detection and 3D face tracking, and the two C++ libraries that were developed in the process. The first part of the talk will give an introduction to detecting facial landmark points and work through a hello-world code example that presents and uses the superviseddescent library, a cross-platform library for cascaded regression that can be used to solve problems like landmark detection or pose estimation. The second part of the talk will present an approach that uses the found landmarks from the first part to use a 3D face model to track a person's face. With the library presented in the process, we hope to make 3D models easier to use and more widespread in the community. Both libraries are designed to be lightweight and simple to use, and try to follow modern C++11/14 programming paradigms. The talk concludes with my views on code sustainability in academia and a wish list of standard library features for computer vision.
CppCon Call for Lightning Talks
Do you have something to say to C++ programers? Can you say it in five minutes?
CppCon 2016 Call for Lightning Talks
by Michael Caisse
From the call:
Lightning talks are fast paced, short presentations often sprinkled with humor and intrigue. The popular 5-minute talks present topics that are interesting to C++ programmers and are open to speakers at all experience levels.
CppCon 2015 Pruning Error Messages From Your C++ Template Code--Roland Bock

Pruning Error Messages From Your C++ Template Code
by Roland Bock
Summary of the talk:
Many template libraries are regarded with ambivalent feelings by developers: On the one hand, such libraries can offer wonderful functionality. On the other hand, they are dreaded for the sheer amount of error messages spilled out by the compiler when there is even a small bug in the developer's code. This talk will demonstrate several techniques to drastically reduce the amount of compiler output in case of errors (with real-life examples, of course).
