Hi-res here.

Channel 9 has just posted a recording of my intro talk at C++ and Beyond 2011 last month in Banff. Here’s the link: C++ and Beyond 2011: Why C++.

It’s a keynote-y talk, not a technical talk, but we felt it was important to address an important trend involving the language. The goal is to share a perspective and rationale for why of late there’s such a resurgence of interest in C++ — both across the industry, and within Microsoft.

Whether or not you agree with the perspective and rationale, I hope you enjoy it!

After the end of the C++ and Beyond event earlier this month, Charles Torre interviewed all three of us for Channel 9.

I thought it came out really well, and stayed firmly focused on C++ — including even during the parts we talked about D and other languages, where the focus was on how their best parts could be applied to C++.

Charles also taped more of the seminar, including the panels and my opening ‘keynote-y’ talk about the what’s and why’s of the C++ Renaissance. Some of those will also appear on C9 over time; I’ll blog about them as they go up.

Some highlights of this particular interview:

[00:00] Event debriefing

[01:38] Scott on C++ developers

[03:18] Modern C++

[04:17] Why D, Andrei? And what from D could and should be brought into C++?

[17:25] What problems does D solve that C++ can’t?

[22:03] C++ and D interoperability (COM is old, but COM is good)!

[24:22] C++11 and Beyond

[26:01] Herb, ISO C++ Committee’s next phase – what are you going to do? [note: see also more details in my trip report for the standards meeting held the following week]

[28:22] Scott, Andrei and Herb share perspectives on the ISO standards process, philosophies of language design, what C++ gets wrong, what it gets right

[49:48] Perspectives on this year’s event and if/when C++ and Beyond will happen again

The summer 2011 ISO C++ meeting was held on August 15-19 in Bloomington, Indiana, USA on the wonderful Indiana University campus. The minutes will be available at the 2011 papers page in a couple of weeks.

As previously announced, C++11 was unanimously approved just days before the standards meeting, so this was the first post-C++11 meeting. As planned, at this meeting we focused on processing some bug reports (defect reports, aka DRs) and have some initial discussion of the ‘what’s next’ variety. As expected, no decisions were made about whether we should consider new language extensions soon — that discussion will likely happen at our next meeting in February.

The big news out of last week’s meeting was on the standard library side: There was a clear decision that the library working group is ready to consider new library extensions, starting with the file system library proposal that was already accepted for post-C++11. The following announcement and instructions were read into the minutes:

The C++ committee Library Working Group welcomes proposals for library extensions which will be considered starting in the February 2012 meeting. We have not yet set out an overall timeline for future library extensions, but are ready to consider new proposals at this point.

To increase the chances of your proposal being accepted by the committee, we strongly recommend that a committee member willing to champion your proposal (this could be you yourself, or a delegate) attend upcoming meetings to help shepherd your proposal through the process.

It’s possible that this will take the form of a second library extensions technical report along the lines of the very successful Library Extensions Technical Report 1 (aka TR1). Whatever the form, it’s clear that the first order of business besides maintenance of the C++11 standard will be a new round of extensions to the C++ standard library.

Personally, I think that’s exactly what needed to happen at this meeting, and I’m very happy to see it take place. ASIO or thread pools, anyone? Maybe parallel algorithms, and concurrent containers? Stay tuned.

Looking forward

It’s our tradition to schedule one meeting a year outside the continental United States, and preferably outside North America, because this helps international participation by making it easier for people from all parts of the world to attend. Next year, as we’ve done before, this “un-American” meeting will be the Kona meeting, which is closer for folks in eastern Asia and Australia who may wish to attend.

Here are the planned dates and locations for upcoming ISO C++ standards committee meetings:

• February 6-10, 2012: Kona, HI, USA
• August or October, 2012: Portland, OR, USA

[Update: “C++11” is now the confirmed name — Geneva informs me that they plan to have it published in a matter of weeks, and then we’ll have ISO/IEC 14882:2011(E) Programming Languages — C++, Third Edition. The second edition was C++03, a Technical Corrigendum, or bug patch, that contained no new features. This is the first major revision with new features.]

The final ISO ballot on C++0x closed on Wednesday, and we just received the results: Unanimous approval.

The next revision of C++ that we’ve been calling “C++0x” is now an International Standard! Geneva will take several months to publish it, but we hope it will be published well within the year, and then we’ll be able to call it “C++11.”

I want to extend my thanks again to Bjarne Stroustrup for sharing his work with the world and continuing to help move it forward, and to all of the participants whose hard work went into achieving this important milestone in the history of a great language. Thanks!

I’m happy to report there’s a new show on Channel 9 that focuses on native code development in C++. It’s called “Going Native”… iTunes podcast here, Twitter @C9GoingNative.

From the description:

C9::GoingNative is a show dedicated to native development with an emphasis on C++ and C++ developers. Each episode will have a segment including an interview with a native dev in his/her native habitat (office) where we’ll talk about what they do and how they use native code and associated toolchains, as well as get their insights and wisdom—geek out. There will be a small news component or segment, but the show will primarily focus on technical tips and conversations with active C/C++ coders, demonstrations of new core language features, libraries, compilers, toolchains, etc.

We will bring in guests from around the industry for conversations, tutorials, and demos. As we
progress, we will also have segments on other native languages (C, D, Go, etc…). It’s all native all the time.

You, our viewers, fly first class. We’ll deliver what you want to see. That’s how it works.

Go native!

I just posted two more sessions I’ll be giving next month at C++ and Beyond. (Aside: If you’re interested in coming, register soon; there are now only 11 seats left.)

• “C++ Renaissance.” I’ve been asked to give the opening “Welcome, Everyone!” keynote talk at C&B 2011, and it’s time to cover an increasingly open secret: After a decade-long affair with managed languages where it became unfashionable to be interested in C++, C++’s power and efficiency are now getting very fashionable again. At the same time, C++ has been getting easier to use; key productivity features from the C++0x standard (aka C++11), like auto and lambdas, are increasingly widely available in commercial compilers and making using C++ easier than ever before without sacrificing its cornerstone — efficiency.This opening 40-minute talk covers the reasons why C++ is now enjoying a major renaissance, and why that will continue to grow over the next few years because of industry trends from processor design to mobile computing to cloud and datacenter environments.We already know that C++ is “the” language of choice for demanding applications. Here, we’ll cover why “demanding applications” increasingly means “most applications” and will be the bread and butter of our industry for the foreseeable future. We’ll see why and where other languages are still appropriate, but why C++’s applicability and demand is now again on an upswing more so than it has been for over a decade.
• “How to Teach Today’s C++.”  With the C++ Renaissance gathering steam, I’ve personally noticed a growing need to train developers who are now turning or returning to C++. These developers don’t need to be taught how to program, but they aren’t familiar with how clean it is to write code using today’s C++. The key is: What is the best and clearest way to teach the essentials of today’s C++ — both what to teach, and what not to teach?This session shows that it is possible to show a very clean path through today’s C++ that is available to production developers right now, including use of key C++0x features already supported in many compilers, that shows how clean C++ code can be and how it compares favorably to code written in managed languages while still retaining its longstanding efficiency advantage.Many attendees coming to C++ and Beyond are experienced developers, often in senior or leadership positions. Your company may look to you to define or personally provide training in the best development techniques, whether through team brownbags or formal training sessions. As developers continue to come back to C++, you will find yourself increasingly called upon to help them quickly learn what “modern C++” really means today, and how clear and compelling it can be. This “train the trainers” session is intended to provide the foundation for that training, and give you the tools you need to train others, as we welcome them (and welcome them back) to our good friend C++.

I’ve already posted these other sessions, which round out my solo talk slots (not counting panels where Scott and Andrei and I will also all participate):

• “C++ and the GPU… and Beyond.” I’ll cover the state of the art for using C++ (not just C) for general-purpose computation on graphics processing units (GPGPU). The first half of the talk discusses the most important issues and techniques to consider when using GPUs for high-performance computation, especially where we have to change our traditional advice for doing the same computation on the CPU. The second half focuses on upcoming C++ language and library extensions that bring key abstractions for GPGPU — and in time considerably more — directly into C++.
•  “Exceptional C++0x (aka C++11)” that shows how the new features in C++0x change the way we solve problems, our C++ coding style, and even the way we think about our code. I’ll demonstrate that with code that works today on existing compilers, using selected familiar examples from my Exceptional C++ books. This is not rehashed material, as I’ll assume you’re already familiar with the pre-C++0x solutions (I’ll provide links to read as refreshers before the course), and then we’ll analyze and solve them entirely the 21st-century C++ way and see why C++0x feels like a whole new fresh language that leads to different approaches, new and changed guidelines, and even better solutions. As Bjarne put it: “Surprisingly, C++0x feels like a new language: The pieces just fit together better than they used to and I find a higher-level style of programming more natural than before and as efficient as ever.” This talk will show why — deeply, madly, and truly.
