The use of Singleton is often justified by the will of being able to easily refer to a unique object from any point. Giuseppe Puoti describes an alternative:
Singleton revisited

From the article:
It happens quite often to deal with those annoying objects, used everywhere in your applications. This may be because of a poorly designed application but, sometime, it is simply an inevitable condition...

C++ Braced Initialization
by Edouard of quasardb
From the article:
Since C++ 11 it's possible to use braces for construction and initialization. Although this is something you could ignore for the code you write, it's obviously important to know for the code you may read.
If you have a couple of years of experience in C++, the temptation can be great to keep your old habits because "All these new features are useless! The language is bloated! Those people in the committee!".
Let's make sense out of the bloat...

This is Malte's third article on hash table design. His solution shows favorable performance against std::unordered_map, boost::multi_index, google::dense_hash_map, and more. Malte includes intuitive descriptions of why each design decision was made and what tradeoffs might exist. The article also describes some interesting artifacts in the implementations of other hash table implementations.
I Wrote The Fastest Hashtable
by Malte Skarupke
From the article:
There are many types of hashtables. For this one I chose
- Open addressing
- Linear probing
- Robing hood hashing
- Prime number amount of slots (but I provide an option for using powers of two)
- With an upper limit on the probe count
I believe that the last of these points is a new contribution to the world of hashtables. This is the main source of my speed up, [...]

Since the overview on the current papers for Kona, I wanted to know more about reflection...
Reflections on the reflection proposals
by Jens Weller
From the article
A few weeks ago I wrote a short overview over the most interesting papers for the current C++ Committee meeting in Kona, Hawaii. The big surprise was that there were many papers on reflection, while there already is a very detailed proposal for reflection.
With the C++ committee currently in Kona discussing lots of proposals, there will be some changes to the on going effort for reflection, but the current proposals are detailed enough to give an overview.

A virtual container.
Generating Sequences
By Anthony Williams
From the article:
I was having a discussion with my son over breakfast about C++ and Python, and he asked me if C++ had anything equivalent to Python's
range()function for generating a sequence of integers. I had to tell him that no, the C++ standard library didn't supply such a function, but there were algorithms for generating sequences (std::generateandstd::generate_n) into an existing container, and you could write something that would provide a "virtual" container that would supply a sequence as you iterated over it with range-for...

The Observable C++ library has a new feature: observable expressions.
Observable C++ expressions – using the Observable library

A nice round up on the first year of the C++ User Group in Sofia:
C++ User Group Sofia first year
by Dimitar Mirchev
From the article
Some time in November 2015 we decided that it is a shame that we do not have a C++ User Group in Sofia, Bulgaria, and we decided that instead of waiting to just make it. This is a retro and an overview of what happened in our first year. I hope you find it helpful and inspirational.

A quick post on the current - and final - solution to use TinyMCE3 with Qt:
HTML Text Editor - final solution
by Jens Weller
From the article:
In the last post about my HTML Text Editor, I mentioned that while the editor worked like it should, other things didn't. I was able to fix at least some of the driver related issues, but kept seeing random crashes. So I decided to try out a different solution, instead of going on a long and tiring debugging trip.
