A nice talk by Mads Torgersen just went live on Channel 9 about C#’s non-blocking Task<T>.ContinueWith() library feature and await language feature, which are a big hit in C# (and Visual Basic) for writing highly concurrent code that looks pretty much just like sequential code. Mads is one of the designers of await. If you’re [...]

Reader Q&A: What does it mean for [[attributes]] to affect language semantics?
Posted in C++, Reader Q&A on 2012-04-05 | 9 Comments »
Followup on this earlier question, @bilbothegravatar asked: @Alf, @Herb – I don’t quite get the [[noreturn]] example. While it may (not) compile on VC++, (as far as I understand) it does not carry any semantic meaning, and, what’s more, it is *perfectly* safe for any compiler that sees [[noreturn]] to just ignore it — the [...]
Reader Q&A: auto and expression templates
Posted in C++, Reader Q&A on 2012-04-03 | 9 Comments »
Motti asked: While you’re dealing with reader’s Qs…. In your keynote in “Going Native” you mentioned that type inference should almost always be used, except for some obscure cases with expression templates. Yes. To give people context, the idea is when declaring local variables, prefer to use auto to deduce the type. For example: This [...]
Reader Q&A: When will better JITs save managed code?
Posted in C++, Reader Q&A on 2012-04-02 | 49 Comments »
In the comments on last week’s interview, MichaelTK asked: @Herb: You mentioned two things I don’t fully understand in your talk. 1) Why would C++ be a better choice for very large scale applications than NET/Java? I mean the zero abstraction penalty (which is more a JIT compiler issue and not intrinsically hardwired into C#) [...]
Reader Q&A: Keywords and Attributes
Posted in C++, Reader Q&A on 2012-04-02 | 11 Comments »
Referring to C++ AMP, a reader emailed me to ask: Are you going to replace restrict keyword with new C++11 attribute feature [[]] ? No, because restrict is a language feature and [[attributes]] are specifically designed to be ignorable and shouldn’t be used for things having language semantic meaning. During the ISO C++11 process, I [...]
Interview: C++–A Language for Modern Times
Posted in C++, Talks & Events on 2012-03-29 | 21 Comments »
Last week I spent 30 minutes with interviewer Robert Hess to talk about the differences between managed and native languages, and why modern C++ is clean, safe, and fast – as “clean and safe” as any other modern language, and still the king of “fast.” The interview just went live today on Channel 9. Here’s [...]
C++ and Beyond 2012: Aug 5-8, Asheville, NC, USA
Posted in C++, Talks & Events on 2012-03-26 | 6 Comments »
February and March have been killer busy, so that I forgot to repeat an important announcement here: registration is open for C++ and Beyond 2012! I’m looking forward to teaching for three days again with Scott Meyers and Andrei Alexandrescu at one of the top C++ conference highlights of the year. This year, C&B will [...]

The spring 2012 meeting of ISO/IEC JTC1/SC22/WG21 (C++) was held on February 6-10 in Kona, Hawaii, USA. Here’s the major takeaway: This is going to be a busy year as investment in C++ across the industry continues to increase, and that’s good news for C++. Here are some highlights from the meeting. Attendance This was [...]
VC++11 Beta Available, Supported For Production Code
Posted in C++, Microsoft on 2012-02-29 | 38 Comments »
Earlier this month, I announced in my GoingNative talk C++11, VC++11 and Beyond that Visual C++ 11 Beta would be available in February. Today’s the day: You can download Visual Studio 11 Beta here. Interestingly, VC++11 is being distributed under a go-live license, which means that Microsoft supports using this compiler to write production code. [...]
Going Native Sessions Online
Posted in C++ on 2012-02-08 | 15 Comments »
Thanks to everyone who came to Redmond and/or watched online to participate in Going Native 2012, last week’s global C++-fest. It was a lot of fun, and generated a lot of useful and important talks that we hope will help continue disseminate understanding of C++11 throughout the global C++ community. All the videos are now [...]
