Episode 40 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Dr. Greg Law to discuss reverse debugging with Undo Software.
CppCast Episode 40: UndoDB and Live Recorder with Greg Law
by Rob Irving and Jason Turner
About the interviewee:
Dr. Greg Law is co-founder and CEO at Undo Software. He has spent nearly 20 years writing systems-level code, including novel kernel designs and networking architectures in academia and at a variety of start-ups. Greg finds it particularly rewarding to turn innovative software technology into “real” business development. He still gets to write some code, although sadly most of his coding these days is done on aeroplanes. Greg lives in Cambridge, England with his wife and two children.

Explications of the noexcept keyword:
Modern C++ Features – keyword `noexcept`
by Arne Mertz
From the article:
I have written about handling exceptions some time ago, and about the levels of exception safety last week. What I have not touched yet are exception specifications. I will catch up on those with this post.
C++98 had the possibility to denote the types of exceptions that could be thrown from a given function by using
throw(<exception list>). In theory, the runtime had to check if any exception emitted by the function was indeed in that list or derived from one of the types in the list. If it wasn’t, the handlerstd::unexpectedwould be called...

The monthly update of C++ User Group Meetings at Meeting C++:
C++ User Group Meetings in January 2016
by Jens Weller
From the article:
The monthly overview on upcoming C++ User Group meetings! There is a new C++ User Group in Iasi, Romania and a lot of C++ User Groups which are meeting in January!
Maybe you want to start a C++ User Group in 2016? Also feel free to contact me on the topic!

C++Now 2016 will be held in Aspen, May 9–14, 2016.
From the invitation:
Building upon the resounding success of previous BoostCon and C++Now conferences, C++Now 2016 will present leading speakers from the whole C++ community.
The C++Now Conference is dedicated to discussion and education about C++, an open and free language and standard. Our Conference will focus on discussion and education about open source software usage and developments in the C++ developer and user community. To reflect the breadth of the C++ and Boost communities, the conference includes sessions aimed at three constituencies: C++ and Boost end-users, hard-core library and tool developers, and researchers pushing the boundaries of computation. The program fosters interaction and engagement within and across those groups, with an emphasis on discussion.
As a multi-paradigm language, C++ is a melting pot with the most compelling ideas from other programming communities blending in powerful ways. Historically, some of the most popular sessions at C++Now have highlighted these concepts, from DSLs to functional programming to transactional memory and more. Bring your C#, Python, Ruby or Haskell influences to bear in an environment that will broaden their exposure.At C++Now 2016 we would like to focus on the now established C++11 and C++14 standards and how those standards shape C++’s future. However, by no means is this intended to restrict the topics of proposals we hope to see. Any other topic related to C++, as described below, is suitable for submission.
This year's window for submitting is shorter than normal. Submissions must be in by January 29th, less than four weeks away.

Quick A: they are the same
Recently on SO:
Quick Q: C++11 auto declaration with and without pointer declarator
The declarations are exactly equivalent.
autoworks (almost) the same as template type deduction. Putting the star explicitly makes the code a bit easier to read, and makes the programmer aware thatbar2is a pointer.

An interesting article:
A flexible lexicographical comparator for C++ structs
by Björn Fahller
From the article:
We've all hand crafted comparison operators for structs with many members, and we've all cursed the tedium. It's all right for equality comparison, but lexicographical ordering relations is a different story when there are more than two members.
Hopefully all C++ developers have by now learned about the std::tie()-idiom.
struct S { int a; int b; int c; }; bool operator<(const S& lh, const S& rh) { return std::tie(lh.a, lh.b, lh.c) < std::tie(rh.a, rh.b, rh.c); }

A nice introduction to C++ exceptions:
Levels of Exception Safety
by Arne Mertz
From the article:
Exceptions are part of C++. They are thrown by the standard library classes, and sometimes even if we are not really using the standard library. So, unless we are in a very restrictive environment like embedded programming and have exceptions disabled in the compiler, we need to be prepared and deal with the fact that exceptions simply can happen.

A nice and short (5-minute read) entrepreneur's perspective about technology choices while starting a modern web company, with nice shout-outs to Folly, Proxygen, and Wangle:
Starting a tech startup with C++
by James Perry
From the article:
A lot of my peers think it is bizarre that I am building a cloud service with C++ and not with a dynamic language — such as Ruby or Python — that provides high productivity to ship quickly.
It started to question my own judgement to use C++ and I decided to research whether it is good idea or not.

As we enter 2016, here is another reminder of just how much has happened for C++ in just the past year:
Interlude (a C++ 2015 retrospective)
by Agustín "K-ballo" Bergé
From the article:
One year down the road, 2015 has gone by but not without modifications to the C++ lands. Several Technical Specification (TS) documents were published, and heavy work continues to go into both existing and new ones. Meanwhile, work is underway for what it is intended to be C++17...
... During 2015, the C++ lands grew bigger at an outstanding rate! As the TS model -- which allows to decouple and publish work independently from the standard -- is proving to be a success, 2016 it's certainly looking to be a good year for C++.
