Madrid's C++ meetup is organizing a Coding Dojo at Tuenti's HQ (calle Valverde, ID required).
Title: Coding "dojo" C++ moderno (C++11, C++14)
Organized by C++ Madrid
Several katas will be proposed by Manu Sánchez, Diego Rodríguez-Losada and Esteve Fernández which will be solved and discussed in common. Read more in the link above [in Spanish].
We've got a full house already!! Thanks for your interest.

The schedule for the upcoming ACCU 2017 conference in Bristol, UK from 2017-04-26 to 2017-04-29 has been published.
ACCU 2017 Schedule
by ACCU conference committee
About the schedule
Again we have very strong C++ tracks this year!
Beside a closing keynote by Herb Sutter, where he wants to make a public announcement on an upcoming C++ development, there will be great C++ talks by members of the ISO C++ committee, other known C++ speakers and new faces to the C++ world.
Four full day tutorials take place the day before the conference, three with C++ content.
So don't forget to register.

The January listing of upcoming User Group meetings!
C++ User Group Meetings in January
by Jens Weller
From the article:
The new year has begun, and as I just returned the listing of the User Group Meetings is a bit late...
Yet still, 37 Meetings in January are listed, 7 of them in Austin, as there is a study group for Modern C++ now.
There are 3 new C++ User Groups: Nashua, NH, Vienna (Qt), Austin (Mentoring & Study Group).

C++Now 2017 will be held in Aspen, May 15–20, 2017.
C++Now 2017 Call for Submissions
From the invitation:
C++Now builds upon the resounding success of previous BoostCon and C++Now conferences, We look forward to considering your proposals, among those from leading speakers from the entire C++ community, to make C++Now 2017 even better.
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 computing. 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 blended 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.
Presentations at C++Now 2017 should generally focus on the now established C++11 and C++14 standards, the upcoming C++17 standard, 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 February 3rd, less than four weeks away.

A very interesting plugin for our blogs:
A new way of blogging about C++
by Yehonathan Sharvit
From the article:
This blog post is about to show a new way of blogging about C++.
Look at a typical blog post about C++: The post usually presents a couple of code snippets. As I see it, there are two pains with code snippets:
- they contain the input and the output but not the actual evaluation of the input
- it’s impossible for the reader to modify the output...

An interesting point of view and implementation of a variant in one article!
My take on variant
by Jonathan Müller
From the article:
C++17 is going to add std::variant. To quote the linked documentation, it is a “type-safe union”. A union is like a struct, but can only store one member at a time. This has many applications, but sadly it doesn’t mix well with non-trivial types, you have to call the destructor yourself etc. Furthermore, nothing prevents you from accessing a union member that isn’t active.
std::variant fixes that. It correctly calls the destructor when switching the active member, it prevents invalid access, etc. However, I’m not quite happy with it and I needed an implementation now. So I’ve decided to implement my own variant as part of my type_safe library.
It was a fun challenge and since my previous attempt was two years ago, I could improve it a lot. Let’s go through some of my design decisions.

Who did not measure wrongly?
Heap fragmentation or how my micro-benchmark went wrong
by David Gross
From the article:
Micro-benchmarking code always looks simple: a few variables, a small for loop and two std::chrono calls. I think this simplicity is an illusion. Micro-benchmarking is either complicated or inaccurate...
