CppCon 2016: Practical Performance Practices--Jason Turner

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:

Practical Performance Practices

by Jason Turner

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

In the past 6 years ChaiScript's performance has been improved by nearly 100x. This was not accomplished by adding a virtual machine or performing dynamic recompilation. Instead, these increases have been accomplished by moving to more simple, cleaner, idiomatic C++ and by following some simple rules. We will outline these concepts with examples for how they both simplified code while improving performance.

CppCon 2016: STL Algorithms - why you should use them, and how to write your own--Marshall Clow

STL Algorithms - why you should use them, and how to write your own

by Marshall Clow

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

One of the most powerful features of the C++ standard library is the collection of basic algorithms. Everyone knows about sort and copy, but there are is a lot of powerful capabilities in the other algorithms as well. In this talk, I will explore some of the algorithms in the library, and give a rationale for writing your own, along with examples.

The motivation for writing your own algorithms is that you can create generic building blocks that can be used over and over again in your library or application, and which will allow your to program at a higher level of abstraction. Instead of thinking, "how do I sort this vector", you just call std::sort. The same should apply to the algorithms that are specific to your domain - once you write them.

CppCon 2016: Garbage In, Garbage Out: Arguing about Undefined Behavior...--Chandler Carruth

Garbage In, Garbage Out: Arguing about Undefined Behavior...

by Chandler Carruth

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

There has been an overwhelming amount of tension in the programming world over the last year due to something that has become an expletive, a cursed and despised term, both obscene and profane: **undefined behavior**. All too often, this issue and the discussions surrounding it descend into unproductive territory without actually resolving anything.

In this talk, I'm going to try something very bold. I will try to utterly and completely do away with the use of the term "undefined behavior" in these discussions. And I will unquestionably fail. But in the process of failing, I will outline a framework for understanding the actual root issues that the software industry faces here, and try to give constructive and clear paths forward, both for programmers and the programming language.

And, with luck, I will avoid being joined on stage by any unruly nasal demons.

Did you ever use them?

C++ Online Compilers

by Arne Mertz

From the article:

Online compilers can be useful tools to quickly compile a snippet of code without having to install a proper compiler on our computer. They can be especially useful to play with the newest language features, to share code snippets online or to compare different compilers...

corsl - Coroutine support library--Alexander Bessonov

Interesting library

corsl - Coroutine support library

by Alexander Bessonov

From the article:

corsl stands for "Coroutine Support Library" and consists of a number of utility classes and functions that simplify asynchronous programming in Windows. It is inspired by an amazing cppwinrt library, developed by Microsoft.

cppwinrt was created as a language projection for Windows Runtime, which is supported by Windows 8 or later operating systems. It is impossible to use in prior Windows versions.

One of the goals of corsl library was being able to use it under Windows Vista or later operating system...

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...
