In yesterday's session, I showed a Windows 8 store app that loads an image and then draws an animated ripple over it.

If you would like to get the code, and more importantly the documentation that explains the code, it's on Codeplex. Mixing and matching a little DirectX into your Windows 8 C++/CX app is remarkably easy, so why not take a quick look?

The week of April 8th, I'll be in Bristol, UK, attending ACCU. I'm looking forward to it tremendously - there is a great lineup of sessions and I only wish I could have spared the time to stay on for the C++ committee meetings that will follow it. I am, however, making the most of my time in that delightful city. Having enjoyed Guy Smith-Ferrier's presentations in several different locations, including my own East Of Toronto .NET User Group, I can now turn the tables and present at his.

Of course I want to do a C++ talk. But it's not a C++ group. So to be fair, I've decided to do two talks:

First, Use All of Visual Studio to Become a Better Developer

Most developers know how to use Visual Studio to do the basics of being a developer. You can create a solution, add projects to it, edit code, and run it. Easy, right? In this session, I want to show you how to be a better developer by using parts of Visual Studio you might not know about. Save hours of debugging time, move around your code more smoothly and don't lose your place, see what you want to see and find what you need to find. Demos will be in C# with Visual Studio 2012.

Second, C++ in 2013 – Why on earth?

There are so many languages a developer could use today. Yet some developers still use C++. Some developers are learning C++ when they already know C# and other younger languages. This session will show you why that is happening, and why you might want to learn the new C++ yourself. It's nothing like the C++ you remember, and it can be a very useful language for you to know.
Please do register for these, and I hope to see you there!

Over the last few weeks, I've been accumulating links to appearances of mine, and it seems like a good idea to share these.

  • OReilly webcast: This is a reasonably horrible recording (sound quality and video size) of a webcast I did back in August. It shows why C++ AMP is so cool and why you might care about it. I recorded it to promote the book but I'm not very happy with how it turned out. You'll probably do better with the recording of my Tech Ed talk.
  • Pluralsight interview: This is specifically about my Using Visual Studio 2012 course. You can download the audio or read the transcript as you prefer.  My favourite quote from the conversation:
It’s not just like, oh, I saved five seconds. I can go home five seconds earlier today. It’s that you’re less likely to forget what you were doing because you don’t have to put so much time into the mechanics and you just stay in flow. And to me, that’s a ramping up of two or three times the amount of code I can produce when I use everything the tool has to offer.
  • Dot Net Rocks panel at DevIntersection: Here Scott Allen, Michele Leroux Bustamante, Woody Pewitt, and I discuss whatever we feel like, with occasional leading questions from Carl and Richard, and some Canadian whisky too.

Even though I haven't been blogging much, I have been doing a lot, and I hope these links will help you to discover some of it.

Don McCrady, who with Jim Radigan did an inspiring talk on performance at Build this year, has blogged about a proof-of-concept project that adds C++ AMP to CLANG and LLVM using OpenCL underneath instead of using DirectX the way Visual Studio does. This is super cool! As Don says:

When Microsoft announced C++ AMP back in June 2011, we told you that we would release the C++ AMP specification under the Microsoft Community Promise – essentially opening up the specification to allow any C++ compiler implementer to add C++ AMP to their compiler. Shevlin Park serves as an example of the platform portability potential intended by the Community Promise.

Do read Don's post and follow the links to learn more about Shevlin Park. The praise for C++ AMP as a programming model, and the likelihood that multiple compilers will support it, should make you feel all warm and fuzzy about learning it. You might even want to use my book to do so :-)

One of the stickers for the badge this year was to attend an 8:30 session. I achieved that by going to Alive with activity: Tiles, notifications, and background tasks which, to be honest, I chose as much to see what Kraig Brockschmidt is doing lately as to learn about tiles and toast. But I'm glad I went, because it was a very good talk.

I've come to Redmond so many times, but I never particularly noticed the colours changing. This week they've been spectacular. I had some meetings in other buildings so I was able to get out of the giant lines at least long enough to take pictures of the giant lines :-)




And yes, it rained, but they were ready for that:




I really like the vibe that came from being on campus. Speakers tended to get up from their desks, jump on a shuttle or walk over, pull on the shirt and talk to us. I really got the sense we were being welcomed into their home.

I also went to Tips for building a Windows Store app using XAML and C++: The Hilo project - how could I not, since I was on the project. Excellent summary of some hard-learned lessons and one you should totally download and watch.

Build this year is less focused on announcing things (though the Windows phone and native C++ material is brand new) and more on drilling down into topics that we've had a year to experiment with and want some deep study on. Most of the speakers are from product teams. What's fun for me is that most of the attendees are very motivated and here to learn.

I'm also enjoying how full the rooms are for C++ sessions. Here's Tarek's Day 1 session:



BTW, that was session 3-000 demonstrating that (a) the sessions are numbered using zero-based indexing and (b) the C++ sessions were first on the list.

And here's the C++ performance talk from right after the keynote this morning:



This room was standing room only. It's possible all the C++ talks were, I don't always sit at the back where I can see whether people are standing back there or not. And you may not be able to tell from the picture but there were plenty of young developers there too.

There was also a nice session on Project Austin which is a lovely reference app showing how to use DirectX in a Windows Store app. You can get the code from Codeplex and take a look at it yourself or just use it to take beautiful notes on a tablet.

Speaking of reference apps, Hilo (which I've written about before) is now an official sample in the SDK and on the Dev Center. There's a Hilo session here at Build too. Within a day or two these links should have recordings and slides for you to download.

Want to know more about C++ at Build? Here's less than two minutes on just that topic. If you can, please watch Herb's talk on Friday. It promises to be exciting!

I really enjoyed my evening in Nashville. It was fun answering the question: C++ - Why on earth? I think I even convinced a few of you.

Of course the biggest Nashville attraction for me is my friend Billy Hollis:

Look what a luxurious meeting room they have! Couches and tables and general comfort. And yes, I got to see the inside of the RV:

If I got you interested in C++, you might like some links:

Thanks for the visit, and I hope to be back!

Here's an amazing grand finale to the Dot Net Rocks Roadtrip this year -a full on developer conference in Las Vegas, Dec 9th - 12th.

I love this answer to "What is DevIntersection?"

This three-day conference marks the final stop on the USA leg of the .NET Rocks! Visual Studio 2012 Launch Road Trip! DevIntersection is a developer conference PLUS the recording venue for the last stop of the three-month road trip hosted by Richard Campbell and Carl Franklin. We're bringing together some of the best speakers (and our personal friends) for a conference that is relaxed and educational, plus forward looking as you and your company start to figure out what to do with Windows 8 and Visual Studio for the next few years. Our attendees tend to be .NET software developers plus other members of their teams. DevIntersection is an educational onsite conference for anyone who is attached to a .NET development programming project who is looking to use Visual Studio to develop apps for desktop, web and mobile platfoms.

I have two breakout sessions - one on C++ AMP and one on developing for the Windows Store in C++. No .NET in either one of them; this is a conference for expanding your horizons, after all.

For $1595 you get three full days of sessions. And if you register in October (hurry!) you will also get a new tablet. Build sold out in hours, so this is your chance to get access to deep and current information for developers across the Microsoft ecosystem. See you there!

Hilo is a reference project written in C++/CX for Windows 8 by the Patterns and Practices team. I was delighted to be part of this project and think it turned out very well. I use the Hilo codebase to remind myself how to do certain things when writing a Windows Store app in C++ (something I'm in the middle of doing for another project.) The accompanying document is rich in best practices for Windows 8 development, async work, modern C++, unit testing, and more. Now the latest version has been released, updated for Windows 8 RTM.

Hilo itself is a photo viewer. Before you roll your eyes, bear with me. I actually think it's better than the one that ships with Windows 8. It shows you some of your pictures as a sort of overview:

Click on one to interact with it. You can right-click to bring up both the app bar at the bottom and a nice strip-navigation control at the top:

If you want to see something cool, use Cartoon Effect. This leverages C++ AMP to cartoonize the picture. I've shopped this image a little to reduce the width (pulled the appbar in from the edges) but the cartoon work was done by Hilo - and super quickly.

If you have any thoughts of writing Windows Store apps, and C++ is a possibility for you, get over to Codeplex, download the Hilo code and the .chm file, and get reading!

I’ve been writing a book, though I swore I wouldn’t write any more books, and it’s finally done! You can buy a Kindle version from Amazon or an e-book directly from O’Reilly today. The paper copies will be ready in about a week and you can order them from O’Reilly or Amazon. The book is published by Microsoft Press, but O’Reilly handles the actual production of the books.


 I’ve got a page dedicated to the book with links for you to buy it, get the code, submit errata, and whatever else you might want. (If you think something’s missing, comment here and I’ll try to take care of it.)

Two years ago or so, when Visual Studio 2010 launched, the crazy duo of Richard Campbell and Carl Franklin – if you’re a Dot Net Rocks listener, they’re the voices in your head – took their show on the road and drove an RV across the USA holding live Dot Net Rocks evenings pretty much every night for weeks on end. Each city featured a surprise “rockstar” flown in for the occasion. I did St Louis and had a great time. Now they’re doing it again and this time announcing us in advance – I’ll be in Nashville Oct 24th.

Registration is free, and please do register using the big red Register button for your city (I hope to see you in Nashville). You can track them online too and follow the #dnrRoadTrip hashtag on Twitter.

If you’re in Toronto, don’t miss the October 13th Saturday-a-ganza at the Microsoft Canada offices featuring Michele Leroux Bustmante! I know I won’t!

I'm headed to Australia tomorrow (I won't get there till Thursday though) and I'm going to be doing some C++ talks while I'm there. Both are aimed at folks who haven't been keeping up to date on all that's been happening in the world of C++ over the last few years.

On Tuesday, July 10th, I'll do a free Tech Breakfast on the new features of the C++ language in the standard once called C++0x and now called C++ 11. I'll demonstrate how a lot of these features are already in Visual Studio 2010 and some in Visual Studio 2012. It runs from 9am to 11 am in Sydney, and you do need to pre-register.

Then all day Wednesday, July 11th, I'll do a course on modern C++ development with Visual Studio 2010 and 2012. I'll cover language changes, tool changes, drill into my favourite feature - lambdas - and show some of the cool things they enable, and give you some advice on best practices for writing C++ today. This course costs $300 Australian and will be held in Sydney just once.

I realize many people who read my blog don't need to come and learn this material. But perhaps you know someone who does? There is room in both sessions for more people - and I want to reach as many people as possible, so please spread the word! Registration links for both session are on the SSW page announcing them.

As I am soon to discover first-hand, Australia is a very long way from North America. So when Adam Cogan makes the trip, he often extends his stay to see more people or places. Last September when we all gathered for //build/, Adam tacked a mini Canada tour onto his North American stay and we got together for a quick chat near my home. Part of it was filmed and (after a long delay to cope with the sound issues) is now available on the SSW TV site.

We talk about C++ and why it has advantages over managed code in some cases, about C++ AMP, and about tablets, leading to this moment:



It's just a 7 minute video, so give it a listen!

I've been putting my schedule together for the talks I want to attend at Tech Ed North America and Tech Ed Europe this year. While I wasn't looking, a bunch more C++ content was added.

In Orlando:

Plus some language agnostic sessions that chose to put C++ in their session descriptions, which is a new thing these days.

Now as it happens, Tech Ed North America is sold out, so if you're not registered yet, you have three choices: join the waiting list, watch these sessions online, or get your boss to agree to a slightly larger T&E budget and head to Tech Ed Europe in Amsterdam just two weeks later. There we will have:

  • PRC08, my all day Monday precon: C++ in Visual Studio 11: Modern, Readable, Safe, Fast
  • DEV316, Tuesday at 4:30 pm: Application Lifecycle Management Tools for C++ in Visual Studio 11 by Rong Lu
  • DEV368, Wednesday at 2:45 pm: Visual C++ and the Native Renaissance by Steve Teixeira
  • DEV322, Thursday at 8:30 am: Building Windows 8 Metro style Apps with Visual C++ 11 by Rong Lu
  • DEV367, Thursday at 4:30: Building Windows 8 Metro Style Apps With C++ by Steve Teixeira
  • DEV334, Friday at 1:00 pm: C++ Accelerated Massive Parallelism in Visual C++ 11 by me

(Europe doesn't have direct links to the sessions, but they do allow links to the search for C++.) I'll have to miss Steve's talk because Rong and I are going to Belgium, so that one I'll be watching online. 

One way or another, please attend or watch these sessions. There's a lot of new stuff happening!

I am having a very lucky year. I've been nominated and accepted as a judge at the Worldwide finals of the Imagine Cup. I love being around students, and everything I've heard about Imagine Cup tells me that the energy, excitement, and creativity is marvelous to be part of. While I'm there, I decided to stay an extra day (July 11th) so I can offer my one-day C++ training to those who can't make it to Tech Ed in Orlando or Amsterdam. Here's what I'll cover:
  • Modern C++ with the Standard Library
  • Application Lifecycle Management for Visual C++ 11
  • Leveraging Lambdas for the PPL and C++ AMP
  • Best practices for C++ developers today

This is not a free session, but the price is even lower than the Tech Ed precons since I don't have travel expenses to get down there and see you all. If you live in Australia, please register and take advantage of this chance to come and learn what's been going on with C++ while you weren't looking! And if you don't, I'd appreciate it if you could spread the word to those who do.

Some people really go above and beyond for community. They have an idea, and then they make it happen. Take Marc Gregoire, for example. Our names are similar, and we both care about community, C++, and related topics, but we've never met. That didn't stop him from emailing me to see if I would do a user group talk while I was nearby for Tech Ed Europe. Of course I would! And then he arranged for Rong Lu from the C++ team to come and do one as well. Marc has done all the work of getting the room, the travel arrangements, you name it. All I have to do is take a short scenic train ride, and talk about a topic I'm excited about. That part is easy. The organizing part is hard.

It's going to be a very fun evening. I'm going to talk about C++ AMP, and Rong will cover what's new in VC++ 11. I've seen her speak before, and I know you're going to enjoy it. Be there, Wednesday June 27th at the Microsoft offices in Brussels. (I was kinda hoping for Tuesday, so I could make a joke, but Wednesday will be fine.) You need to register, so please do!

This report is well overdue, I know. On April 17th I spoke at the first meeting of the Toronto C++ User Group! The room was PACKED:



And as you can see, there's quite an age range represented. The space was provided by bNotions. It was lovely and airy, and I was thrilled to hear their commitment to community across a variety of technologies:



Once I got started, my challenge was to give the one hour version of this talk, and not the six-hour one I plan to do at my Tech Ed precons in June. Here I am in action (thanks Eran for wandering the room with my camera throughout the talk) explaining the new ranged-based for:




The next meeting will be shared with the North Toronto .NET User Group, covering Windows 8 development in native C++. Yes, the .NET folks want to hear about this, too! I'll see you there June 4th, right?

The times for my sessions at Tech Ed North America and Tech Ed Europe have been announced.

  • PRC08 - C++ in Visual Studio 11: Modern, Readable, Safe, Fast is Sunday, June 10th in Orlando, 10am to 6pm. This is the session for those who've been ignoring C++ and are wondering why they keep hearing about it. Please encourage your friends to attend.
  • DEV334 - C++ Accelerated Massive Parallelism in Visual C++ 11 is Tuesday, June 12th in Orlando, 10:15am - 11:30 am. This session will show you what C++ AMP is all about.
  • PRC08 - C++ in Visual Studio 11: Modern, Readable, Safe, Fast is Monday, June 25th in Amsterdam, 9am to 5pm. The same material as in Orlando, just saving some travel time and costs for attendees :-)
  • DEV334 - C++ Accelerated Massive Parallelism in Visual C++ 11 is Friday , June 29th in Amsterdam, 1pm - 2:15 pm. Again, same material, different continent.

If you or those you influence are not yet registered for the conference in general, and the preconferences in particular (they cost extra and require you to arrive early, so plan ahead) please take care of that as soon as you can. Here are some helpful links:

How's this for a renaissance? People are starting C++ user groups!

  • The Jerusalem .NET/C++ User Group will cover both topics. They've had their first meeting already.
  • The Central Ohio C++ User Group has also had its first meeting and will meet monthly.
  • In Austin Texas they're calling it the C++ Meetup and the description sounds a lot like a user group
  • The Belgian C++ User Group has its first meeting in April

It's so much fun to see this excitement springing up. There seem to be two popular topics for first meetings: either "What's new in C++ 11" or "Writing Windows 8 Apps". I think these two things arriving together - the huge language and library improvements (and the unexpected synergy of the language changes and the library changes) with the chance to write for Windows 8 in C++and XAML - is producing much more interest than there used to be.

And now the fun is spreading to Toronto! No, I'm not founding the group - I'm surely not the only C++ developer in Toronto after all. But I am honoured to be speaking at the first event on April 17th right downtown (pretty much Yonge and Bloor.) I'd love to dive deep into C++ AMP, or show how the Consumer Preview of Windows 8 is easier to code for, but I think I should begin at the beginning, so my talk is titled What happened in C++ 11 and why do I care? and has this abstract:

C++, both the language and the libraries that come with every compiler, is defined by an ISO standard. The latest version of the standard, generally known as C++ 11 after its approval last fall, was optimistically called C++0x throughout the multi-year process that led to its adoption. Many of the language changes (new keywords, new punctuation, new rules) and library changes (genuinely smart pointers, threading, and more) have already been implemented by vendors who were following the standards process closely.
In this session Kate will introduce and demonstrate many of the highlights of C++11 including lambdas, auto, shared_ptr, and unique_ptr. These are all supported in Microsoft’s Visual Studio 2010. You can see how to make your code more readable and expressive, easier to update, more correct (less bugs and memory leaks) and faster, not by trading off among those possible constraints but by adopting modern C++ which gives you improvements in all four areas at once. If you’ve been ignoring the Standard Library, for example, you must see how lambdas make all the difference and open a world of productivity to you.
A sneak peek of the next version of Visual Studio will show you even more C++11 goodness.

If you've looked at my Pluralsight courses, you'll know that my biggest challenge is going to be fitting this into an hour plus Q&A. This will be an overview, an overture if you like, and should whet your appetite for the meetings to come!

Please register as soon as you can, please spread the word, and I hope to see you there!

My C++ precon, an all-day session about modern C++, has had a slight title change and is now called PRC08, C++ in Visual Studio 11: Modern, Readable, Safe, Fast. The content is still the same. My high level outline is:

  • Modern C++ with the Standard Library (demo of strings, shared pointers)
  • Application Lifecycle Management for Visual C++ 11
  • Leveraging Lambdas for the PPL and C++ AMP
  • Best practices for C++ developers today
This is all day the Sunday before Tech Ed Orlando starts, June 10th. You don't have to be registered for Tech Ed to attend a pre-con. It's a great way to get caught back up on what's been happening with C++ over the last decade or so. It's really not the language you remember. I plan to show you what's fun and amazing about it. Forget all that pointer-to-pointer-to-pointer and manual memory management stuff you may remember, and get ready to see how C++ can be simple, fast, and genuinely useful in some surprising ways.

People keep on releasing interviews with me. If you're willing to listen to them, I'm more than willing to keep on talking. There's remarkably little overlap in all of these.

On The Tablet Show, Richard and Carl (yes, that Richard and Carl) asked me about C++ in this wacky new world of Windows 8. We had the usual freewheeling conversation and covered a lot of ground in 49 minutes.

For PluralSight, Fritz asked me questions about my latest course, and the industry in general. This one's just ten minutes, and there's a transcript if you'd rather read than listen.

In recent years the speed at which Tech Ed session recordings have appeared has increased dramatically. I can now sometimes watch a missed session while I am still at the conference, in time to seek out the speaker and ask questions if I want to. But one thing that hasn't changed is that the precons, the all-day sessions held the day before the conference starts, are not recorded. Whether you attend one or not, you can't watch afterwards.

This has two consequences. First, if you want to see what's been happening to C++ lately and why people who've ignored it for the last ten years are suddenly interested again, you have to register (Orlando, June 10th or Amsterdam, June 25th) and you have to come and listen to me live. Second, if you do that, you want to take plenty of notes because you won't be able to just watch the video again later if there was a part where you got caught up in something on Twitter and just weren't listening.

Here's what I'm going to do to reduce the note-taking burden for my attendees. (I can't speak for other precon presenters, but you're welcome to ask them.) I will put a number of useful bits and pieces for you to download, using credentials I'll give out on the day. These will include:

  • The PPT decks I will use to present, with some notes added to some slides
  • Written demo scripts for all demos with exact step-by-step instructions (occasionally, it might just say “show the for loop and explain what it is doing”, but if there is code to be added or edited, it is in the script, if there is an option to be set the exact menu choices are in the script, etc.)
  • Zip files of starting points for all the demos and ending points too

During the precon itself, I will collect Live IDs from attendees who would like to be added as a user to a subsite on  my “hosted TFS” preview page, which I am using as a sandbox. This makes it possible to play around with the new ALM features without having to get a site all set up. I am not sure what will happen to this preview site by Tech Ed time, but I’m presuming it will continue to exist all through 2012. That’s the site I intend to use during the ALM (module 2) section of the precon.

I also intend to record each demo in advance – I typically record all my talks when I’m practicing for length and I have a pretty good mike that I use for my PluralSight courses. It's not much effort to edit them so that you can use them for a reference. I would have put this in the bulleted list but I don't want to 100% promise that I'll get them all nicely edited in time. I hope to provide them.

Specifically for module 4, Best Practices, I am planning to write a short paper that makes the same points in prose – sentences, code snippets etc – and if it's ready in time, I'll bring printouts of that paper to the session (leave me a comment if you think that would be useful.) It will be on my web site eventually, but I am trying to push myself to get it written before Tech Ed so it can be at the precon.

Anything else you think would help to reduce the note-taking burden? It's a full day, and a lot of us are out of practice receiving information in pieces of that size. Let me know!

It's been a week-and-a-bit that the beta of Visual Studio 11 has been out. I'm using it more than Visual Studio 2010 at the moment - in both Windows 7 and Windows 8, and for C++ projects exclusively at the moment. (Say what you will about the C++ Renaissance, but the fraction of my consulting, writing, and coding that is C++ has taken a major uptick in the last  6 or so months.) I'm getting used to the look, and I'm certainly motivated to use more keyboard shortcuts :-)

Herb has a nice blog post that summarizes the C++ features in this release. You can read the details there, I'll just summarize briefly:
  • Complete Standard Library for C++ 11. Especially the async and threads stuff. Standard!
  • Some more language C++ 11 features. Range for is the big one here.
  • C++ AMP. You know I care about this one!
  • The continuation (.then) syntax of PPL, which makes WinRT asynchronicity much more readable.
  • Windows 8 - both C++/CX and WinRL

And there will be more coming, sooner than "Visual Studio 12" whenever that might be. There will be out of band releases with more goodies as they get finished. If you care what gets done (and released) in what order, you can tell the team. I took the survey myself - I care about uniform initialization, defaulted constructors, and then some other bits and pieces at lower priority. Since they aren't just going to gather them all up and release them a few years from now, order matters. Share your opinion, and you're more likely to get what you want.

Recently the Tech Ed people interviewed me for a profile that is now live. You can read it on their blog. We are all starting to work our way towards being ready for June. The content catalogs are partially public for both Tech Ed North America and Tech Ed Europe. If you search on C++, you'll find more than just my precon, by the way.

North America:

Europe:

Who is giving those talks? Well I am doing the precons in both places - that's official. And I wrote the abstracts for the other two talks, so I'm pretty sure I'm giving those too. I would love to see you there. And if you have colleagues who are coming to Tech Ed who really don't "get" why C++ is different these days, please encourage them to join me for the all-day precon that answers precisely that question.

I've been excited about C++ AMP since it was first announced back in June. What's C++ AMP? It stands for Accelerated Massive Parallelism and it's about harnessing thousands of cores on accelerators like GPUs. You can speed up some applications by a factor of 10 or more. Not 10%, 10x. And you don't have to learn some C-like language, you get to work in C++. It's done almost entirely with libraries, which means you can use C++ AMP from a variety of applications, including Metro apps for Windows 8.

If you check my Concurrency category you'll see I've been writing code (and words) for months now. I just haven't been putting those words here on my blog. Instead, they're going into a book, for Microsoft Press! Soon, I will have some chapter drafts available for review. If you're interested, I've set up a page with some details, and some links for those who want to learn more.

There's increasing media coverage, including Peter Bright at ars technica and Darryl Taft at eWeek, and last week the spec was released to the public under the Microsoft Community Promise license. This means other compiler vendors can implement C++ AMP in their own compilers, allowing even more developers access to heterogeneous hardware and massive speedups for data parallel calculations. Herb Sutter mentioned it in the Day 2 keynote at GoingNative, the Visual C++ Blog included a link, and Soma blogged about it too.

Dive in! There's a lot to learn. And plenty of samples to play with. I'll post updates here as I go.

The minute this was announced, I knew I had to go.

Two days of "C++ today and tomorrow" with the bright lights of C++ today? Just try and keep me away! I'm so glad I was there - it was AMAZING and FANTASTIC and just generally wonderful. For me, personally, seeing so many old friends was a big part of it. The C++ team, other C++ MVPs, people I went to university with, and so on. It was also wonderful to see so many young people - including speakers, but also attendees, who were clearly in their 20s (and a few who were obviously in their teens.) After Chandler's talk I told someone "we can retire now: the future of C++ is in good hands." The speakers were not "the usual suspects" at a Microsoft event either. At a panel at the end of the second day, someone asked about C++ and the cloud and one of the answers was to indicate three speakers sitting next to each other: "Microsoft guy, Facebook guy, Google guy. Where isn't C++ in the cloud?" While that was a great cloud answer, I think it also highlights how inclusive this was - it was a C++ conference held at Microsoft, not a Microsoft conference.

Some fun quotes I happened to write down:

  • “if it’s that ugly, it must be good” - Bjarne, on why some newbies imitate horrible code written long ago by their heroes
  • “write C-style code, expect C-style errors” - Bjarne again
  • “we know where bugs hide” – Bjarne (they hide in large tracts of complicated code)
  • "dot dot dot is where the fun begins" - Andrei
  • "real code is not supposed to fit on slides" - Andrei
  • "this is legal" - Andrei (we needed to be reassured since it rarely looked legal)
  • "if you're using new or delete, you're doing it wrong" - Herb (it's true!)

And Chandler's talk was very much a 2012 talk, with lolcat-like interjections and Simpsons references and even a how-agile-is-this update with a picture of Oscar Wilde in reference to Andrei's earlier off-the-cuff description of some template error messages (aka template barf) as being "a small novel by Oscar Wilde." The humour level was very high, much of it self-deprecating - no-one, not even the coiners of the terms, thinks RAII or SFINAE are great names, but what the heck, they're the names we use.

Even the little things here were so well done. Herb opened the conference by dedicating it to Dennis Ritchie, which I found extraordinarily touching and appropriate. He opened day 2 by celebrating the 20 year anniversary of Microsoft C7 which was C++ 1 for them, with Visual C++ appearing in the next release. There on the podium was the two foot long, 44 pound box, with multicoloured plusses all over it, in which it shipped.

And what was inside? A lot of books, and a lot of 3.5" floppies (I took this picture earlier, before the box headed to campus):

There are 5 or 6 floppies in each bag and apparently each bag had a part number of its own.

This conference was far more than a trip down memory lane, of course. It was a two-day Valentine from Microsoft to the C++ community, a demonstration of the "new growth" in modern C++ and the power and capability that is there for those who are prepared to start using the new features, and a chance for all of us to accelerate the learning we have to do. I so hope you were able to be there, or to catch the energy by watching it live and following tweets from those of us who had to share the bon mots and the fun. But if not, the on-demand videos are almost all there now. Here are the links:

Bjarne Stroustrup: C++11 Style

Hans Boehm: Threads and Shared Variables in C++11

Stephan T. Lavavej: STL11 – Magic && Secrets

Andrei Alexandrescu: Variadic Templates are Funadic

Panel: The Importance of Being Native (Bjarne, Andrei, Herb, Hans) 

Herb Sutter: C++11, VC++11 and Beyond

Chandler Carruth: Clang - Defending C++ from Murphy's Million Monkeys

Andrei Alexandrescu: Static If I Had a Hammer

Bjarne Stroustrup and Andrew Sutton: A Concept Design for C++

Panel: Ask Us Anything! (all speakers)

Fair warning: both of Andrei's talks, and the Concepts talk, are hard. This is cool new stuff that we are all learning about. There is no shame in pausing, rewinding, and giving something a second listen. Look, Chandler was running through pitfalls and problems that Clang catches, and showed some code with a problem I couldn't spot. A few minutes later in the Q&A, Bjarne asked him to clarify just what the problem was. Made me feel better!

Chances are you won't be able to watch any of these on fast forward, or skip any of them. So I'm asking you to invest 12 hours of your life to watch all of them. Do it! You won't regret it!

PS: They gave us shirts (it's all about the shirts for developers) with real code on the back and this on the front:



Highly appropriate. Of course, it's not a comeback for those of us who never left. But still...
