A trip report from the just-concluded ISO C++ meeting:
Trip report: Winter ISO C++ standards meeting (Kona), C++17 is complete
by Herb Sutter
From the article:
C++17 is done!
The big news is that we completed C++17, which dominated the work of the meeting: C++17 is now technically finished and being sent out for its final ISO balloting. All that remains for C++17 now is some ISO red tape and minor touch-up to get it officially published, which is expected to be just mechanical...

Episode 94 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Robert Ramey to discuss his Safe Numerics library and the process of submitting libraries to both Boost and the C++ Standards Committee.
CppCast Episode 94: Safe Numerics with Robert Ramey
by Rob Irving and Jason Turner
About the interviewee:
Robert Ramey is a freelance C++ programmer for around 20 years. He has worked on a variety of applications including desktop retail applications, embedded systems on tiny micro controllers and combinations of these. For the last 10 of those years he has been active in the Boost Organization and
- Author and Maintainer of the Boost Serialization library
- Instigator of the Boost Library Incubator (www.blincubator.com)
- Given talks on Boost/C++ related topics at C++Now and CPPCon
- Written articles in print periodicals such as Software Development and ACCU Overload
Of late his interest has become more focused on practical approaches to improving program correctness. This has motivated recent talks at CPP Con ( boost units library, C++ and abstract algebra) and most recently the Safe Numerics library - which has very recently been accepted as an official Boost Library.

constexpr evolves!
Constexpr Additions in C++17
by Arne Mertz
From the article:
Last year, I have written about constexpr and compile time constants in general. Last week, the Draft International Standard for C++17 has been sent to its ballot. Time to provide some updates to earlier posts!

What do you think?
Does const mean thread-safe?
by Anthony Williams
From the article:
There was a discussion recently on the cpplang slack about whether const meant thread-safe.
As with everything in life, it depends. In some ways, yes it does. In others, it does not. Read on for the details.

Do you know what is clang-tidy and how to use it?
Clang-Tidy, part 1: Modernize your source code using C++11/C++14

From the article:
This blog series will introduce the clang-tidy utility from the Clang/LLVM project and show how to use it to automatically refactor C++ source code and integrate with your build system, as well as how to use the tool on other platforms than Unices.

Episode 93 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Ben Deane from Blizzard Entertainment to talk about C++ game development and more.
CppCast Episode 93: C++ Game Development at Blizzard with Ben Deane
by Rob Irving and Jason Turner
About the interviewee:
Ben started in the games industry in the UK in 1995, when he got hired at Bullfrog straight after graduating from university. While there he worked on several games there like Syndicate Wars and Dungeon Keeper. By the late 1990s he had stopped using C and was allowed to use C++ at work. In 2001 he moved to Kuju Entertainment and did a couple of games on XBox and PS2, then in 2003 he was hired by EA again and moved to Los Angeles, where he worked on the Medal of Honor series. He's always been a network game programmer, and in 2008 after a project cancellation at EA, he joined Blizzard as a lead engineer on Battle.net, working on technology for all of Blizzard's games. Today he's a principal engineer at Blizzard and the technical lead on the Battle.net desktop application. He's also a functional programming hobbyist who tries to use what he learns in Haskell to write better C++, and in recent years he has given several C++ conference talks at C++Now and CppCon.
