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...

The C++14 Standard -- Mark Nelson

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.

On the Ground at CppCon 2014

I composed this review of CppCon 2014, and think it might be interesting to the ISOCPP audience.

 

On the Ground at CppCon 2014

I’ve just returned from the week-long CppCon 2014 in Bellevue, Washington. Here’s what I experienced.

I’ve absorbed a great deal from a variety of C++ developer conferences -- CppNow, Going Native, C++ And Beyond -- but always virtually, via video and webcast. This was an opportunity to jump into the thick of things and participate in person. With community heavyweights like Herb Sutter and Scott Meyers in attendance I knew the content would be stimulating and informative. (Honestly, the speaker list featured nearly every name in the “C++ royalty” that you could imagine. I smiled to myself seeing Bjarne Stroustrup standing in the registration line like he was just another attendee.) So when the conference’s early-bird admission opened in March, I eagerly sent in my hard-earned dollars and blocked off the week of September eighth on my calendar...

Trip Report: CppCon Just Ended -- Charley

As folks are heading home, a number are writing up trip reports for the companies or colleagues. Here's one from the Qt community:

CppCon Just Ended

by Charley

From the post:

Apologies for cross-post qt-interest and qt-dev, but wanted to be sure both groups saw the announcement for next year (20-25 Sep-2015).

WOW AGAIN for a great conference.  Really heavy-hitters there, with information I don't know is available elsewhere...

This was a "first-year" conference, and it was a huge success (about 600 people, it exceeded their goals).  There is a strong possibility that it will double in size for next year, and they have a venue that can handle that...

Even though it was a "first-year" conference, it is interesting to note that a "culture" is clearly starting to form.  It was incredibly open, and collegiate, and supportive across the different industries and companies -- for newcomers and for experienced people (although it is most definitely a place where experienced people can finally discuss their advanced issues when they have nobody else at their company to help).

These were incredibly smart people merely coming together to talk about problems and solutions and experiences in using and growing C++.  I'm going back again next year (assuming their restraining order against me has expired by then).

CppCon 2014 is done -- Jon Kalb

Wrapup:

CppCon 2014 is done

by Jon Kalb

From the article:

Some of the announcements made at the close of the conference include the fact that conference tee shirts are now available on our on-line store, presentation notes will be available on git hub, and our dates for next year will be September 20 – 25, 2015.

Before looking to next year and CppCon 2015, I’d like to thank all the people that made CppCon 2014 such a big success. First I’d like to thank the sponsors whose support is critical to the existence of the conference. I’d also like to thank all the presenters whose content made the conference what it is; the keynotes, the regular program presenters, the panelists and moderators, the Open Content presenters, and the Lightning Talk presenters. These presenters are busy, smart people, but they’ve taken the time to create presentations that excited attendees from all over the world.

I’ve a very big thanks for the conference staff who did so many things in so many ways to make this week-long experience valuable for our almost six hundred attendees.

Finally, and most importantly, I want to thank the attendees. They are the real value and attraction of this conference.

I can’t wait to see you all again next year.

Jon
