News and articles from around the web

Some slides and videos from cppcon have started to appear. See the slides from Bjarne Stroustrup's keynote (which focus on the Core Guidelines project), as well as Herb Sutter's slides on supporting ownership annotations in C++ (this will be familiar to anyone who has used Rust). Videos are starting to appear on the CppCon Youtube channel.

A Microsoft blog says something about their plans to rejuvenate MSVC. "We will continue to invest in improving our compiler with a goal towards making it fully standards compliant".
