CppCon 2015 videos also on Channel 9

By Blog Staff | Sep 30, 2015 04:39 PM | Tags: None

CppCon 2015's sessions, panels, and lightning talks were professionally recorded and will be available online worldwide for free in about a month. As you probably saw already on this site, the team made a special effort to post the big five talks early -- the three keynotes and two other daily plenary sessions are all available online now.

To try to make the videos as widely available as possible, like last year the videos are being posted on two different sites: YouTube and Channel 9. Feel free to use whichever works best in your country.

Again, the rest of the talk videos will take about a month to post. The slides will also be available soon and you will be able to find them at github.com/cppcon/cppcon2015. Enjoy!

Video available: Eric Niebler, "Ranges for the Standard Library" -- CppCon 2015 Friday endnote

By Blog Staff | Sep 30, 2015 04:27 PM | Tags: None

niebler-cppcon2015-v.PNGCppCon 2015's inspiring endnote video is now available below. This is last of the rush-processed plenary sessions posted quickly (see the Video feed for the others). Of course, there'll be more: Like last year, all the sessions, panels, and lightning talks were professionally recorded and will be available online worldwide for free, but processing well over 100 videos is a lot of work and it will take about a month before they can be available; your patience is appreciated.

Here is the talk, available on both YouTube and Channel 9 (use whichever works best in your country). Slides will be available soon at github.com/cppcon/cppcon2015:

Ranges for the Standard Library (YouTube) (Channel 9)

by Eric Niebler, CppCon 2015

From the talk's outline:

Range-based interfaces are functional and composable, and lead to code that is correct by construction. With concepts and ranges coming to the STL, big changes are in store for the Standard Library and for the style of idiomatic C++. The effort to redefine the Standard Library is picking up pace. Come hear about one potential future of the STL from one of the key people driving the change.

I've been doing C++ professionally for the past 20 years, first for Microsoft, then as an independent consultant. Right now, I'm working on bringing the power of "concepts" and "ranges" to the Standard Library with the generous help of the Standard C++ Foundation. Ask me about the future of the Standard Library, or about range-v3, my reference implementation for C++11.

Video available: Chandler Carruth, "Tuning C++: Benchmarks, and CPUs, and Compilers!" -- CppCon

By Felix Petriconi | Sep 29, 2015 06:20 AM | Tags: performance efficiency advanced

Chandler's talk about benchmarking, cheating the compiler's optimizer and optimizing code from the recent CppCon is online.

Tuning C++: Benchmarks, and CPUs, and Compilers! Oh My! (YouTube)

by Chandler Carruth, CppCon 2015

From the talk's outline:

A primary use case for C++ is low latency, low overhead, high performance code. But C++ does not give you these things for free, it gives you the tools to control these things and achieve them where needed. How do you realize this potential of the language? How do you tune your C++ code and achieve the necessary performance metrics?

This talk will walk through the process of tuning C++ code from benchmarking to performance analysis. It will focus on small scale performance problems ranging from loop kernels to data structures and algorithms. It will show you how to write benchmarks that effectively measure different aspects of performance even in the face of advanced compiler optimizations and bedeviling modern CPUs. It will also show how to analyze the performance of your benchmark, understand its behavior as well as the CPUs behavior, and use a wide array of tools available to isolate and pinpoint performance problems. The tools and some processor details will be Linux and x86 specific, but the techniques and concepts should be broadly applicable.

The Problem, The Culprits, The Hope--Tony “Bulldozer00” (BD00) DaSilva

This is another call to all C++ programmers, it is time to change!

The Problem, The Culprits, The Hope

by Tony “Bulldozer00” (BD00) DaSilva

From the article:

Bjarne Stroustrup’s keynote speech at CppCon 2015 was all about writing good C++11/14 code. Although “modern” C++ compilers have been in wide circulation for four years, Bjarne still sees:

I’m not an elite, C++ committee-worthy, programmer, but I can relate to Bjarne’s frustration...

Going Native 42: Bjarne Stroustrup interview at CppCon

Interviewed by Steve Carroll, development manager for Visual C++

The 42nd episode is here with a special guest: Bjarne Stroustrup is joining us from CppCon to share more about his historic CppCon keynote this week. His focus is on how we can all write good C++14 code.

Interview highlights:

  • [02:13] What is the keynote about?
  • [02:47] How do we write modern C++ code?
  • [03:46] Guideline support library and Static analysis
  • [04:39] Call to action for the C++ community!
  • [05:34] Enhancing productivity by eliminating whole classes of bugs
  • [06:01] Extending the C++ core guidelines
  • [07:44] What do you expect from these static analysis checkers?
  • [10:47] How can I get started?
  • [14:47] Other talks about this at cppcon

Video available: Sean Parent, "Better Code: Data Structures" -- CppCon 2015 Wednesday keynote

By Blog Staff | Sep 26, 2015 03:31 PM | Tags: None

parent-cppcon15-v.PNGThe wonderful week of CppCon 2015 has just concluded, and we now have the Wednesday keynote video available below. (Reminder: All the sessions, panels, and lightning talks are being professionally recorded and will be available online worldwide for free. Like last year, expect them about a month after the conference ends. We're making a special effort to make the daily keynote/plenary sessions available early.)

Here it is:

Better Code: Data Structures (YouTube)

by Sean Parent, CppCon 2015 day 3 keynote

The standard library containers are often both misused and underused. Instead of creating new containers, applications are often structured with incidental data structures composed of objects referencing other object. This talk looks at some of the ways the standard containers can be better utilized and how creating (or using non-standard library) containers can greatly simplify code. The goal is no incidental data structures.

We hope posting these few highlights during and shortly following CppCon can help to let everyone in the worldwide C++ community share in the news and feel a part of the gathering here in the Seattle neighborhood this week. Even if you couldn't be here in person this year to enjoy the full around-the-clock technical program and festival atmosphere, we hope you enjoy this nugget in the video presentation.

Bitesize Modern C++ : noexcept--Glennan Carnie

By Adrien Hamelin | Sep 24, 2015 02:29 PM | Tags: c++11 basics

What is the use of noexcept?

Bitesize Modern C++ : noexcept

by Glennan Carnie

From the article:

We have some basic problems when trying to define error management in C:

  • There is no “standard” way of reporting errors. Each company / project / programmer has a different approach
  • Given the basic approaches, you cannot guarantee the error will be acted upon.
  • There are difficulties with error propagation; particularly with nested calls.

The C++ exception mechanism gives us a facility to deal with run-time errors or fault conditions that make further execution of a program meaningless...

Video available: Herb Sutter, "Writing Good C++14 by Default" -- CppCon 2015 day 2 plenary session

By Blog Staff | Sep 24, 2015 11:46 AM | Tags: None

sutter-cppcon15-v.PNGCppCon is in full swing, and once again all the sessions, panels, and lightning talks are being professionally recorded and will be available online worldwide for free. Like last year, expect them about a month after the conference ends.

This year the team is trying to get a few of the big talks up early while still busily recording the 100+ others still in progress. Yesterday, they posted Bjarne Stroustrup's opening keynote video less than 48 hours after the live talk, and we're pleased to see that as of this writing over 10,000 of you have already enjoyed it online in its first day!

Today, the team posted the video for Herb Sutter's Day 2 plenary talk, which he described as "part 2 of Bjarne's keynote" with a focus on type and memory safety with live demos. If you couldn't be at CppCon on Tuesday in person, we hope you enjoy it:

Writing Good C++14... by Default (YouTube) (slides)

by Herb Sutter, CppCon 2015 day 2 plenary session

This talk continues from Bjarne Stroustrup’s Monday keynote to describe how the open C++ core guidelines project is the cornerstone of a broader effort to promote modern C++. Using the same cross-platform effort Stroustrup described, this talk shows how to enable programmers write production-quality C++ code that is, among other benefits, type-safe and memory-safe by default -- free of most classes of type errors, bounds errors, and leak/dangling errors -- and still exemplary, efficient, and fully modern C++.
