Alexander Stepanov Introduces Bjarne Stroustrup at CppCon 2014—A9 Videos

cppcon-stepanov.PNGThe 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.

Exceptions, error codes, and assertions in C++—Joseph Mansfield

mansfield.pngOne 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...

First community planning session was a full success

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.

Trip Report: My Trip to CppCon—Jens Weller

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++...
