From the organizer of Meeting C++:

My Trip to CppCon

by Jens Weller

From the article:

I just returned yesterday from my trip to Bellevue/WA for CppCon. Its been 10 awesome days, and a ton of fun. It was an honor to support this idea from day one as a community sponsor. I already posted some images of CppCon 2014 at facebook and G+.

... And then from Monday till Friday there was the awesome content. I had often a hard time to choose which talk to see next, as with 6 Tracks there often was a scheduling conflict. All the keynotes delivered good content and Mike Acton really gave us something to talk about. One of the highlights in the talks was for me the talk about using boost fusion for wire protocols, ...

Marking as Deprecated in C++14 -- Joseph Mansfield

Now that C++14 is preparing for publication, get the details on the new [[deprecated]] attribute.

Marking as Deprecated in C++14

by Joseph Mansfield

From the article:

It is common for entities in source code (functions, classes, etc.) to become obsolete or unsafe as a project undergoes development. It's usually a bad idea to remove those entities without any warning, as it'll break any code that interfaces with those entities. Instead, a good practice is to mark them as deprecated in an attempt to discourage their use.

The upcoming C++ release, C++14, introduces the deprecated attribute for specifying that an entity is deprecated.

Embedding Lisp in C++: A Recipe -- Chris Kohlhepp

Look at this image again: That's C++ in Lisp. And that's just for starters...

Embedding Lisp in C++ -- A Recipe

by Chris Kohlhepp

As a teaser, consider this from midway through the article:

Just to recap, so far we have seen C++ calling in-line Lisp; Lisp calling C++; a Lisp REPL inside of a C++ process; a full symbolic Lisp debugger inside of C++; byte compiled and interpreted mode of execution; as well as trivial Live-Programming.

We are yet to see full integration with Lisp’s package management system and fully compiled Lisp code inside of C++...

When Size Does Matter -- K-Ballo

Recently on Tales of C++:

When Size Does Matter

by K-ballo

In the C++ lands every object has mass; for any complete type T, sizeof(T) is greater than zero. This keeps array indexing and pointer arithmetics from collapsing, but it also means that empty objects occupy space. Furthermore, when an empty object is placed in a class next to a bigger member, padding may — and in all likeliness will — be added due to alignment requirements, resulting in an empty member taking more than just one byte of storage.

Certainly something has to be done about this...

Stroustrup on "The Essence of C++" -- Montreal, Canada, on October 7

By Blog Staff | Sep 16, 2014 11:35 AM | Tags: None

Just announced today, Bjarne Stroustrup will be giving a free public talk in Montreal, Canada, on October 7:

Bjarne Stroustrup, celebrated inventor of the C++ language, in Montreal

A free conference presented October 7 by Morgan Stanley and TechnoMontréal

From the press release:

This free event, presented in collaboration with TechnoMontréal, will be held at Place des Arts at 2:30 pm. Only 1,000 tickets are available and can be booked through the Place des Arts box office.

The conference, presented in English, will be of particular interest to software developers. Building on the distinctive foundations of C ++, Stroustrup will examine how new and existing features support (or distract from) programming, and how they promote an innovative style of design that is more efficient. Developers from Morgan Stanley's Technology & Engineering Centre in Montreal will be present to answer questions after the conference.

The Essence of C++
A technical conference with Bjarne Stroustrup
October 7, 2014, from 2:30 to 4:30 pm
(Doors open at 2:00 pm)
Places des Arts, Théâtre Maisonneuve
175 Ste Catherine Street West

Free event – limited seating!

The C++14 Standard -- Mark Nelson

ddj-nelson.PNGToday on Dr. Dobb's:

The C++14 Standard

by Mark Nelson

From the article:

Voting on the C++14 standard was completed in August, and all that remains before we can say it is officially complete is publication by the ISO. In this article, I will visit the high points of the new standard, demonstrating how the upcoming changes will affect the way you program, particularly when using the idioms and paradigms of Modern C++.

The committee seems intent on keeping the standards process in a higher gear than in the past. This means that C++14, having had just three years since the last standard, is a somewhat constrained release. Far from being disappointing, this is a boon for programmers because it means implementers have been able to push out compliance with the new features in real time. Yes, you can start using C++14 features today — nearly all of them if you are flexible on your tool chain...

Less than two weeks till C++ and Beyond Stuttgart

By Blog Staff | Sep 16, 2014 09:57 AM | Tags: None

If you're in Europe and couldn't attend last week's CppCon, you have a closer option available: C++ and Beyond in Stuttgart with Scott Meyers, Herb Sutter, and Andrei Alexandrescu will be held on September 29 through October 1. Registration is still open.

C&B is a different event from CppCon -- a more intimate and interactive seminar, with classic material that the Three Amigos gave at C++ and Beyond in the past, plus breaking updates.
