The CppCon videos will start appearing soon. In the meantime, A9 Videos posted this introduction that preceded CppCon 2014's opening keynote by Bjarne Stroustrup. In six minutes, Alex Stepanov gives a great capsule summary of what makes C++ important, and why it will continue to be important for a long time yet.

One reasoned take on the various error reporting mechanisms in C++ and a policy for deciding when each is appropriate:
Exceptions, error codes, and assertions in C++
by Joseph Mansfield
From the article:
It can often be difficult to decide between the various methods of error reporting in C++. For example, some common advice is that exceptions should only be thrown in exceptional circumstances. Needless to say, this isn't particularly helpful. What exactly is an exceptional circumstance? An exception to what? If we throw assertions into the mix, this can become even more complicated.
In general, functions express a contract to the calling code...

Yesterday I held the first planning session for local C++ communities at the #meetingcpp chat at freenode.My plan is to make this a monthly online meeting, where new user groups can be planned and existing user groups can exchange and connect.
First community planning session was a full success
by Jens Weller
From the article:
Yesterday I held the first planning session for local C++ communities at the #meetingcpp chat at freenode.My plan is to make this a monthly online meeting, where new user groups can be planned and existing user groups can exchange and connect. As this was the first time, and I just returned from CppCon, so I only could announce it a day before. Yet it was a good start, especially the contact to the brazilian C++ User Group is great to have.

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, ...

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
deprecatedattribute for specifying that an entity is deprecated.

I'd like to try something new tomorrow at 17:00 CET:
Tomorrow: Community Planning Session
by Jens Weller
From the article
I spoke at CppCon about founding C++ User Groups and Community work for C++. In general I'd like to give people the opportunity to meet once a month online, and exchange ideas for local C++ User Groups/communities.

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++...

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...
