Effective GoF Patterns with C++11 and Boost -- Tobias Darm

By Blog Staff | Oct 9, 2013 08:54 AM | Tags: intermediate boost

tobias-darm.PNGSpeaking of ACCU 2014, here's an excellent talk from ACCU 2013 showing how C++11 (by itself, and/or with Boost) makes expressing many common design patterns far simpler than using traditional pre-C++11 tools. In fat, are there cases where the design patterns even disappear entirely? Watch to find out.

Expression Templates -- Volker Krause

Expression Templates: How I Learned to Stop Worrying and Love Template Meta-Programming (30 min video) (slides)

by Volker Krause

The speaker's opening words should be enough to get you to set aside a half hour:

"I'm going to talk about template metaprogramming in general and expression templates in particular. And that's obviously something we use every day. <laughter> You laugh, but in half an hour you will see that we actually do..."

 

Abstract:

Contrary to common perception, expression templates are not bizarre meta-programming theory but something you are (possibly unknowingly) using every day. We'll see what they are good for, how they work and and what to do if they don't.

Originally invented by Todd Veldhuizen for the use in the math library Blitz++, expression templates are often seen as one of those esoteric applications of C++ template meta-programming that results in completely incomprehensible code that only Marc and Thiago understand at best, and that gives you compiler errors longer than an average discussion on the right display manager.

In this talk we will try to counter this (wrong) perception, by looking at why and how this (syntactically) indeed somewhat complex code results in very elegant API and often outperforms conventional implementations. On the way we will see that C++ template meta-programming code is actually not that scary, and that template-related compiler errors aren't that bad either.

Now why would this be of interest to the average Qt or KDE developer? Well, since the introduction of QStringBuilder in Qt 4.7 we have expression templates for a very common use case, string concatenations. And if your code is somewhere in KDE Git, it's very likely Laurent enabled the use of QStringBuilder for you already. So, we are not talking about exotic theory here, but about tools you are using every day.

The Universal Reference/Overloading Collision Conundrum -- Scott Meyers

By NoSenseEtAl | Jul 24, 2013 07:22 AM | Tags: intermediate

meyers-nwcpp-13.PNG[Blog suggestion by NoSenseEtAl. Text below added by editor.]

Scott Meyers gave a well-received "beta" talk last week at NWCPP on the topic below, which he described as the most complex Item he's encountered as he prepares his upcoming book Effective C++11/14:

The Universal Reference/Overloading Collision Conundrum

by Scott Meyers

Abstract:

To help address the confusion that arises when rvalue references become lvalue references through reference collapsing, Scott Meyers introduced the notion of "universal references." In this presentation, he builds on this foundation by explaining that overloading functions on rvalue references is sensible and useful, while seemingly similar overloading on universal references yields confusing, unhelpful behavior. But what do you do when you want to write a perfect forwarding function (which requires universal references), yet you want to customize its behavior for certain types? If overloading is off the table, what's on? In this talk, Scott surveys a variety of options.

Though Scott will give a one-slide overview of the idea behind universal references at the beginning of the presentation, attendees are encouraged to familiarize themselves with the notion in more detail prior to the talk. Links to written and video introductions to universal references are available here.

Efficient Programming with Components -- Alexander Stepanov

Video Series: Efficient Programming with Components

by Alexander Stepanov

Performance is essential for infrastructure software. Modern infrastructure software depends heavily on components. Therefore, writing performant code in this environment requires deep understanding of the characteristics of such components. The course will help programmers to improve performance of their code by learning how to use these existing generic components effectively. In addition, it will teach them to extend the library with new high-performance components. Along the way, participants will learn how to use C++ as a high-performance language.The course will be taught interactively with the class discussing, discovering, and developing components together.

Code is available here.
