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:
Threads and Shared Variables in C++11
T. Lavavej: STL11 – Magic && Secrets
Variadic Templates are FunadicPanel:
The Importance of Being Native (Bjarne,
Andrei, Herb, Hans)
Herb Sutter: C++11, VC++11 and Beyond
Clang - Defending C++ from Murphy's Million
Alexandrescu: Static If I Had a Hammer
Stroustrup and Andrew Sutton: A Concept Design for C++Panel:
Ask Us Anything! (all
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...

Perhaps not a great surprise, but today the precons for Tech Ed North America
were announced and mine is there too. It's well described in the previous blog post
and I'll be doing the same material at both events. So if Orlando, June 10th works better for you than Amsterdam, June 25th, terrific and I'll see you there! Registration
is now open.
Monday, January 09, 2012
Yay! Today I got news that registration is open for Tech Ed 2012 in Amsterdam, and with it confirmation that my preconference
has been accepted! This is great news for anyone who loves C++, because it's a C++ all day preconference! The title is C++
in 2012: Modern, Readable, Safe, Fast
and here's the abstract:
is gaining momentum as a development language, so whether you’ve never used C++
or stopped using it a decade ago, it may be time to brush up on your skills.
With a new standard release providing new keywords and capabilities, C++ is a
featured language for many of the new Microsoft technologies and enables
some amazing speed-ups of your application using libraries like PPL and C++
AMP. What’s more, Visual Studio offers tools to native developers that have
only been available for managed developers in earlier versions. This all-day
session will show you what all the fuss is about and give you the skills you
need to understand the advantages of C++ today and how to start applying those
benefits to your application.
Now, if you're an experienced and current C++ developer, you may not need to come to this session. But if you were thinking you needed a refresher, here's a great way to get one, and at the same time look at some of the cool new stuff that is available to you once you know C++. If you've never written a line of C++ code in your life, but you're solid in C# or Java so you know the basic syntax (if, while, etc) you should be able to follow this session, though it won't teach you all the fiddly bits of C++ syntax and make you a C++ developer from scratch. It should, however, give you the inspiration you might need to go and learn all that fiddly syntax, and understand why we have it. I am also hoping there will be a number of relevant breakout sessions you'll want to attend after getting a taste of what C++ developers can do, though we have to wait a little longer to find out about those.
I'm still working on the exact content, but my first draft outline looks something like this:
- 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
practices for C++ developers today
This is 9am - 5pm (all day) the Monday before Tech Ed Europe starts, June 25th. You can register for the precon and Tech Ed now. And tell your friends! I would love to see a TON of registrations to ensure continued C++ content at Tech Eds around the world.
PS: Yes, I know that Tech Ed US is a few weeks before Tech Ed Europe. You didn't miss the US announcement; you shouldn't have to wait much longer for it though.

Work is underway on settling the agenda for Tech Ed, even though it's almost 6 months away. As Brandy explained
a week ago or so, it starts with asking "the usual suspects" for session submissions. Tech Ed is a fairly closed conference - the call goes out to MVPs, RDs, some Microsoft employees and previous speakers. (How do you become a new speaker? Do a great job somewhere else first -Tech Ed is not a beginner's conference. The people who get the call for content can propose great speakers who didn't get the call.) Now they've announced the technical tracks
, which gives you an idea of what you can expect to see covered. There are no huge surprises here: I'm most interested in Architecture & Practices, Developer Tools, Languages & Frameworks, Windows Client and Windows Phone.
What will be next? Announcing the precons. They've already announced the price: $400 if you're attending Tech Ed, and $500 if you're not. They'll say what the precon topics are in early January. But by then, the super early bird discount will have expired. That discount will save you $300. So registering now is like paying only $100 for the precon! If you can decide in January or February, when the precons are announced, you'll still save $200, so it's like your precon is half price. Either way, it's a great deal for a full day of deep training on something relevant to the kind of people who come to Tech Ed.
To be clear, I don't know what the precons are going to be. I will blog as soon as I know. But if you think there's a chance that spending a whole day with someone who really knows their stuff on a topic you need to know (especially one you never got around to learning and feel you should) would be worthwhile, then why not make it official, register for Tech Ed
, and see what gets announced in January?

Pluralsight, for whom I've done a lot of courses
, has revamped their website recently. That includes having drawings or sketches in a lot of places where you might expect photographs. Here's the one they've been using for me, next to the photo it was made from:
I definitely like the sketch better, but lots of people recognize the photo because it's one of the few I use in the various places people want pictures. I also have this one I use on my public Facebook page
I am not sure any of these will help you find me in a crowd. That's one of the reasons that on my business card (and my Twitter profile
) you'll see this one:
More than one person has had an "oh, that's who you are!" moment when I hand them my business card. Yup, that's me!

The second part of my C++ Fundamentals course is now live
on the Pluralsight site. This one covers:
- The Standard Library - string, collections, and the like
- Lambdas - perhaps my favourite C++ 11 feature
- Exceptions - every C++ developer needs to understand exceptions
- Understanding Legacy Code - here's where you'll find out how C++ earned its reputation
These four modules build on the material I covered in part 1
- Context - to set the stage
- Tools - Visual Studio and Visual Studio Express
- Fundamental Types
- User Defined Types
- Flow of Control
- Pointers, Inheritance, and Polymorphism
One of the things I like best about this material is that char* strings and all the special cases to deal with them don't show up until the last module of part 2. Ditto the kinds of arrays you may have first learned. The kinds of gyrations C-style arrays and C-style strings put C++ programmers through are a large part of why people think C++ is hard. With std::string, std:vector, and other goodies from the Standard Library, C++ really isn't hard. Honestly!

I'm in the middle of writing a number of SUPER COOL things that I will blog about as they finish. But interesting things happen even when I'm too busy to blog, and an interesting one happened today.
You know you should have a Pluralsight subscription, don't you? All the training you can watch (some of it by me) for as little as $29/mo? You can't go wrong. And if you're an MVP, or an RD, or a member of BizSpark, you don't even have to pay that! But if you don't have a free subscription and haven't paid for one yet, taking a free course is a great way to see what all the fuss is about.
Well, starting right now, you can do just that! Pluralsight and the Visual Studio folks are providing my Using Visual Studio course completely free. Just visit the Learn Visual Studio page at Microsoft and use the links. And if you like the course, consider getting a subscription - there are scores more that you will like.

Oh my goodness. What a week that was!
Here's how I thought I would do my first summary. Links to videos, discussions of sessions I either went to or tried to go to (more on that in a moment) along with my tweets from the ground, as it were.
My first real tweet Tuesday morning (8:37 California time) was announcing that my PluralSight C++ Fundamentals course had gone live. Then the keynote started. Here are my tweets and retweets along with the time into the keynote I said them:
- 6 minutes: #bldwin totally dominating my stream SS doing a good intro to lean back computing
- 37 minutes: RT @dseven WinRT API'S are natively built into Windows and built to reflect in different languages - C/C++ and .NET. #bldwin
- 42 minutes: Starting at 8PM today, Seattle time, you can download all of the code that attendees at BUILD received. t.co/nuTuwga
- 43 minutes: RT @wkrwk Did anyone notice the UI during the VSE 11 demo is the classic Windows UI? #bldwin
- 48 minutes: #bldwin VS vNext demo is breaking twitter = no hope of following it all
- 50 minutes: RT @andrewbrust Expression Blend is still Grey on Black. It could use a little "fast and fluid," frankly. #bldwin
- 51 minutes: Store menu in VS?? #bldwin #wholenewworld
- 58 minutes: RT @rhundhausen Desktop (#x86) apps can be listed in the #windows8 store as well #bldwin
- 61 minutes: RT @ayus :))) RT @timheuer The Red Shirt is dominant even when not present. #bldwin @scottgu
- 79 minutes, @EdgarSanchez retweeted @rickasaurus asking "I'm interested in hearing more about this new GPU offloading API. Any links? #bldwin" and I answered "Check my blog as the week goes on for GPU stuff"
- 80 minutes: RT @marypcbuk Sinofsky: that gaming PC looks like ice. Angiulo: more like lava, it converts 700w of power to 4.7 teraflops like 3,500 Cray XMPs #bldwinPlatform for Metro style apps
- 87 minutes: RT @Pete_Brown Dude just cracked open a laptop on stage and showed the electronics. Can't beat that #bldwin #geek
- 100 minutes: RT @andrewbrust When will we admit Sinofsky's doing a great job? He's working hard, not just presiding. #bldwin
- 120 minutes: RT @ronnipedersen If you have an iPad, don't watch the build keynote… It'll make you feel like you have bought a C64 #bldwin
- 127 minutes: RT @jonbrasted It is a great day to be a Windows developer. #bldwin #trbbuild
The download surprised me, I didn't think it would be ready for people to try on any old hardware. And the hardware demo was very very good. And sure, I was on instant messenger back to the office saying "it's official" when the rumour was finally confirmed that we were getting tablets. But mostly, I really liked what I saw and wanted to know more, which is what keynotes are all about.
After eating something completely unmemorable, I found my way to the overflow room, always a little more casual and a good place to find "the cool kids". I had already met a number of old friends in the huge keynote session and before it, but here were more. I'll just give you the links to the Big Picture sessions. They are all very good.
- 8 traits of great Metro style apps - a truly excellent session by a presenter who cares deeply about the topic. I tweeted a lot less during this one because it required more active listening.
- Platform for Metro style apps - another very good session during which I just retweeted some other people's "Hey, this stuff is C++" reactions and a link to the session planner app for the phone, which I used heavily.
By this time people were starting to "get it" (including me) and the excitement level was rising. Here's just what I retweeted:
- @coridrew #bldWin is really, really, really making me want to //BUILD/ Windows apps #BestConferenceNameEver #WhoKnew
- @briannoyes Add ref from js project to C++ library - really empasizes this is running native #bldwin
- +@fignewtron iPad limited in many ways to consumption - Windows 8 is production and consumption on many devices. Sales numbers decide winner. #bldwin
- @mcakins Wow, the silence from Apple's camp is deafening! Windows rocks once more! Its 1995 all over again! #bldwin
One more session: Tools for building Metro style apps - I was getting tired at this point. It was a lot to take in. People were lined up the length of the convention centre for tablets. I knew there were enough for all of us, so I went back to my room to edit my pointers module for the PluralSight course so it could "tack on" to the end of the published course. While videos rendered, I had a little back and forth on Twitter with people who had noticed how much fun I was having, and others who were playing with their tablets already. I slipped out to pickup the tablet about 7:30 but didn't open it till the module was done. Then:
- 10:48 pm: got major piece of work done ... yielding to temptation ... tablet here i come #bldwin
- 10:57 pm: How's that for fast setup? Everything's installed.... Trying visual studio next
- 11:11 pm: Just wrote a Win8 C++ app on the tablet with touch keyboard. Built and ran first time. #winning
That's right, I didn't even set up the bluetooth keyboard. People cite Visual Studio as an app you couldn't possibly use with touch. I wouldn't want to do it all day, but I did it! Then I played a bit more.
Day 2 started with another whole keynote
. C++ was front and centre here. Some tweets:
- 17 minutes: RT @seesharp 3D graphics debugging at the pixel level in DirectX. Unreal. #bldwin
- 33 minutes: RT @bgervin killer strategy for MS to help developers make HTML apps for iOS and Android #bldwin
- 34 minutes: RT @tpdorsey RT @EisenbergEffect […] in C++, you can write your own WinRT library, which when built, can be used by C++, C#, VB and JS.
- 34 minutes: RT @jmorrill This new COM and C++ version is not _anything_ like what you think it is. From what I can tell so far...effing amazing!!!!
- 49 minutes: Loved it RT @MichaelDesmond Zander shows off the new image editor in VS11 as he works on a C++ DirectX game.
- 54 minutes: RT @shycohen Moving a VHD while the machine is running is cool. Moving a live VHD is even cooler! :) Will enable amazing things in the future. #bldwin
- 82 minutes: most tattoos ever in an MS keynote
- 95 minutes: RT @seesharp WOAH. Did not expect Steve Ballmer today. Everyone was starting to leave already. Woah! #bldwin
- 97 minutes: RT @carafone 500,000 downloads of #win8 already! #bldwin
- 98 minutes: RT @LACanuck And #Win8 was downloaded 500K times in 12 hrs RT @mashable: RIM Has Sold Just 490,000 PlayBooks - on.mash.to/nEu0dU #bldwin
- 102 minutes: That's what these keynotes were missing! Turns out it's a great time to be a developer. I was worrying, no-one had told me yet #bldwin
- 105 minutes: I've been paid to program since 1979. Keynotes tell me at least once a year it's a great time to be a developer. And they're right. #bldwin
Then it was time for simultaneous breakouts, and that meant choices. You can search the sessions list
as well as I can. The C++ ones
are not to be missed. These are happy people who are delighted to tell us what's been going on, and they're proud of it, too. At 3:13 I tweeted "Went quiet because i am massively engaged with C++ content in packed rooms. Small break between sessions to say "wow!" #bldwin #happycamper
". The remainder of the afternoon was super confusing. People were jumping to conclusions, correcting each other, having opinions about the death of this that and the other. Because C++/Cx (the language extension you use to call WinRT) looks a lot like C++/CLI, people thought it was managed, but it's not, it's all native code and C++ Metro apps get a perf boost from that. The understanding that something amazing and powerful still has COM at the core began to grow. People were reporting trying to use Windows 8 gestures on their iPads and on nontouch screens, showing that the team has made some very intuitive choices. One tweet of mine I want to repeat: "Big props to Aleš Holeček for joining in the Q&A in the last C++ talk of the day when the questions got really Windows-y. Impressed. #bldwin
". Even if you're not a C++ developer, download that session
and watch the Q & A.
Day 3 started with being turned away from a C++ session
, and so going to a different C++ session
that was on at the same time. Several people from the C++ team made the trip with me, giving me a chance to tell them how impressive all this was. Meanwhile on mailing lists, people who weren't onsite and were 12 - 24 hours behind as they waited for session videos to go live were echoing the confusion and dismay of yesterday. It was hard to be patient with them. It's going to make sense, I wanted to tell them. Just hang in there! I took a small break from sessions to watch (and help with) the C++ part of Channel 9 Live (I am still waiting for links to the recording, because I couldn't hear everything they said and I want to) and then to Herb's second talk
- again the room jammed full and dozens turned away, Don Box (who had earlier reminded us COM is still love) blurting out his admiration for Herb as a speaker and the great content, and the terrific line, "We protect against Murphy, not Machiavelli
". What a time to be a C++ developer!
Day 4 kicked off with kind words from Daniel
and a chance to hand out paper copies of the whitepaper I recently blogged. I got some quiet time with various smart people who told me their thoughts on all this. I'm still synthesizing it all. I also was downloading videos like a mad thing. I came home with 22 hours of video to watch and since then have grabbed another 15 or so. Some people began to realize they had over-reacted. Some excellent blogs began to appear - Doug Seven,
for example, had several sensible things to say.
And then it was time to go. Glenn Ferrie tweeted "Writing C++ in the airport #bldwin #WinRT
" and that summed up the week for me. I have a lot of watching, coding, thinking, reading and talking to do so I can establish what all this means. But hey, why not join me? It's a great time to be a developer!
