CppCon 2014 super early bird almost sold out—~20 tickets left

cppcon-144.PNGIf you've been thinking of registering for CppCon, you can save by doing it in the next couple of days. Over at CppCon.org, Boris Kolpackov reports:

Super Early Bird Last Chance

In the past couple of weeks a lot of C++ enthusiasts have registered for CppCon 2014 and as a result we only have about 20 super early bird entries left. If you are planning to attend, this is your last chance to register at the most affordable price.

After the limited Super Early Bird is full, Early Bird registration will be available until the end of June. Student registrations are also available at a heavily subsidized rate to ensure students can take advantage of the program.

Parsing XML at the Speed of Light—Arseny Kapoulkine

Some high-performance techniques that you an use for more than just parsing, including this week's darling of memory management:

Parsing XML at the Speed of Light

a chapter from "The Performance of Open Source Applications"
by Arseny Kapoulkine

From the chapter:

This chapter describes various performance tricks that allowed the author to write a very high-performing parser in C++: pugixml. While the techniques were used for an XML parser, most of them can be applied to parsers of other formats or even unrelated software (e.g., memory management algorithms are widely applicable beyond parsers). ...

Optimizing software is hard. In order to be successful, optimization efforts almost always involve a combination of low-level micro-optimizations, high-level performance-oriented design decisions, careful algorithm selection and tuning, balancing among memory, performance, implementation complexity, and more. Pugixml is an example of a library that needs all of these approaches to deliver a very fast production-ready XML parser–even though compromises had to be made to achieve this. A lot of the implementation details can be adapted to different projects and tasks, be it another parsing library or something else entirely.

C++ and Beyond Road Show 2014—September 29 - October 1, Stuttgart, Germany

Today on the C++ and Beyond blog, Scott Meyers announced that registration is now open for a C&B event in Germany this fall, largely repeating the C&B December 2013 material for the benefit of those who were not able to attend the sold-out event in December.

C&B 2014: September 29 - October 1 in Stuttgart!

with Scott Meyers, Herb Sutter, Andrei Alexandrescu

Maritim Hotel, Stuttgart, Germany
September 29 - October 1, 2014

Note: The web page for the event is in German, but the seminar itself will be given in English.

From the announcement:

You can think of this event as the C&B Road Show, because the organization is a little different from how we’ve done things in the past: Most of the talks will be updated versions of the presentations we gave at C&B 2013. (See the schedule here.) If you were unable to attend C&B this past December, this is your chance to see what you missed. ... [See the] web page for C&B 2014 for all the details of this event.

This will be the only C&B in 2014, so we hope to see you in Stuttgart at the end of September for the first-ever C&B in Europe!

Native Code Performance on Modern CPUs: A Changing Landscape—Eric Brumer

eric-brumer-build-2014.PNGThis C++ optimization talk is one of the highest-rated talks from last week's //build/ conference, and deservedly so.

Be prepared for deep content from a compiler optimizer architect, and quite a bit of subtle dry humor.

Native Code Performance on Modern CPUs: A Changing Landscape

by Eric Brumer
Compiler developer, Visual C++ team

Modern CPUs are fast. Really fast. New instructions, wider vector registers, and more powerful CPUs promise faster code. But reasoning about performance is not as it seems on the surface. This talk will dive deep into how advancements in the latest chips force some rethinking of native code performance, from the point of view of a compiler developer. The performance landscape is changing. Come see what that means.

CppCon 2014 Registration Open: September 7-12, Bellevue, WA, USA

cppcon-173.PNGThe Standard C++ Foundation is very pleased to announce the first annual CppCon.

cppcon-logo.PNG

Registration is now open for CppCon 2014 to be held September 7–12, 2014 at the Meydenbauer Center in Bellevue, Washington, USA. The conference will start with the keynote by Bjarne Stroustrup titled "Make Simple Tasks Simple!"

CppCon is the annual, week-long face-to-face gathering for all C++ users. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in the beautiful Seattle neighborhood and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.

What you can expect at CppCon:

  • Invited talks and panels: The CppCon keynote by Bjarne Stroustrup will start off a week full of insight from some of the world’s leading experts in C++. Still have questions? Ask them at one of CppCon’s panels featuring those at the cutting edge of the language.
  • Presentations by the C++ community: What do embedded systems, game development, high frequency trading, and particle accelerators have in common? C++, of course! Expect talks from a broad range of domains focused on practical C++ techniques, libraries, and tools.
  • Lightning talks: Get informed at a fast pace during special sessions of short, less formal talks. Never presented at a conference before? This is your chance to share your thoughts on a C++-related topic in an informal setting.
  • Evening events and “unconference” time: Relax, socialize, or start an impromptu coding session.

CppCon’s goal is to encourage the best use of C++. The conference is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer community and promote the understanding and use of modern, standard C++ on all compilers and platforms.

Compiler support for C++11 and C++14

C++11 support is still an interesting topic, even that GCC and Clang now fully support it. Also the upcoming C++14 standard is already getting implemented by a lot of compilers. There are two very interesting publications about this topic in recent weeks, first, on italiancpp.org there is a PDF on C++11 and C++14 feature support for Visual C++, Intel, Clang and GCC. Also Just a few days ago, a interesting blogpost about this topic was published on C++Rocks, focussing on compiler and library support:

C++11/14 compiler and library shootout

by C++ Rocks

From the Article:

It’s been almost a year since my last comparison of C++11 support across different compilers, so I decided to take a break from working on my book about C++11/14 features in VS2013, and see how things have changed.

Range Concepts, To Infinity And Beyond

The 4th part in Erics series on ranges:

Range Concepts, Part 4 of 4: To Infinity And Beyond

by Eric Niebler

From the Article:

Last time, I introduced a new concept, Iterable, and showed how it solved many of the problems with pair-of-iterator-style ranges. This time around, I’m going to extend Iterable in small ways to make programming with infinite ranges safer and more efficient. Disclaimer: The ideas in this post are more speculative than in the previous three. I’m looking forward to the disucussion.

C++17: I See a Monad in Your Future!

Thoughts on Monads and Futures in C++

C++17: I See a Monad in Your Future!

by Bartosz Milewski

From the Article:

If you thought you were safe from functional programming in your cozy C++ niche, think again! First the lambdas and function objects and now the monad camouflaged as std::future. But do not despair, it’s all just patterns. You won’t find them in the Gang of Four book, but once you see them, they will become obvious.

Range Concepts, Part 3 of 4: Introducing Iterables

The third part of Eric Nieblers Series on ranges

Range Concepts, Part 3 of 4: Introducing Iterables

by Eric Niebler

From the Article:

In the last two blog posts, I describes the challenges I’ve encountered while building a next-generation range library. In this post, I’ll sketch for you my proposed solution: refinements of the range concepts that allow delimited, infinite, and pair-o’-iterator-style ranges to fit comfortably within the concept hierarchy without loss of performance or expressive power and with increased safety. I’ve built a range library around these concepts that subsumes and extends all of the C++98 STL algorithms and the Boost.Range adaptors, so I can say with confidence that these concepts lead to a useful and consistent generic range library.
