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 ��. Strongly recommended...

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:
Want fast C++? Know your hardware!
by Timur Doumler
Summary of the talk:
As C++ evolves, it provides us with better and more powerful tools for optimal performance. But often, knowing the language very well is not enough. It is just as important to know your hardware. Modern computer architectures have many properties that can impact the performance of C++ code, such as cache locality, cache associativity, true and false sharing between cores, memory alignment, the branch predictor, the instruction pipeline, denormals, and SIMD. In this talk, I will give an overview over these properties, using C++ code. I will present a series of code examples, highlighting different effects, and benchmark their performance on different machines with different compilers, sometimes with surprising results. The talk will draw a picture of what every C++ developer needs to know about hardware architecture, provide guidelines on how to write modern C++ code that is cache-friendly, pipeline-friendly, and well-vectorisable, and highlight what to look for when profiling it.

Using Types Effectively
by Ben Deane
Summary of the talk:
C++ has a pretty good type system, and modern C++ gives us a greater ability than ever before to use that type system for good: to make APIs easier to use and harder to misuse, to make our datatypes more closely express our intent, and generally to make code safer, more obvious in function and perhaps even faster.
This is an interactive session - incorporating games played between presenter and audience, even - taking a look at choices available to us as datatype and API designers, and examining how a little knowledge about the algebra of algebraic datatypes can help. We'll see why std::optional and (hopefully soon) std::variant will quickly become an essential part of everyone's toolbox, and also explore how types can be used to express not just the structure of data, but also the behaviour of objects and functions.
