An observation on using std::size & co with statically sized char arrays:
Just be aware of std::size and static C-strings
by Marco Arena
From the article:
C++17 added support for non-member std::size, std::empty and std::data. They are little gems for generic programming...

Anastasia Kazakova, Timur Doumler, and Phil Nash describe their experience from the recent ACCU conference in Bristol.
ACCU 2018 trip report
by Anastasia, Timur, Phil
From the report
A couple of weeks ago we traveled to Bristol for the annual ACCU Conference with our booth and 4 talks from our team (including a keynotes plenary!) in the main program. In this blog post I (Anastasia Kazakova, PMM for C++ Tools), Timur Doumler (Software Developer in the CLion team) and Phil Nash (JetBrains C++ tools Developer Advocate), would like to share our impressions and some interesting findings we had from the conference.

Well defined semantics for positions and displacements.
Affine Space Types
by Adi Shavit
From the article:
I recently came across a geometric structure that deserves to be better known: The Affine Space. In fact, like many abstract mathematical concepts, it is so fundamental that we are all subconsciously familiar with it though may have never considered its mathematical underpinnings.
This post will introduce the Affine Space structure and focus mainly on its role in the C++ type system, the standard library and for creating new strong types.

Refactoring with C++17 std::optional
by Bartlomiej Filipek
From the article:
There are many situations where you need to express that something is “optional” - an object that might contain a value or not. You have several options to implement such case, but with C++17 there’s probably the most helpful way: std::optional.
For today I’ve prepared one refactoring case where you can learn how to apply this new C++17 feature...

How to Reorder A Collection With the STL
by Jonathan Boccara
From the article:
The STL lets you do plenty of things on collections, and one of them is to reorder the elements inside of the collection. Or, said another way, to perform a permutation on the collection.
Inded, moving elements around a collection typically takes a fair amount of complex code to write, involving for loops and iterators. And it is perhaps the area where the STL generates the most spectacular improvements, by encapsulating those complex operations behing meaningful interfaces.
Let’s see what sorts of permutations the STL offers:
- Lexicographical permutations
- Cyclic permutations
- Random permutation
- Reverse
- Checking for permutations
- Other permutations

Quick A: For convenience.
Recently on SO:
int a[] = {1,2,}; Weird comma allowed. Any particular reason?
It makes it easier to generate source code, and also to write code which can be easily extended at a later date. Consider what's required to add an extra entry to:
int a[] = { 1, 2, 3 };... you have to add the comma to the existing line and add a new line. Compare that with the case where the three already has a comma after it, where you just have to add a line. Likewise if you want to remove a line you can do so without worrying about whether it's the last line or not, and you can reorder lines without fiddling about with commas. Basically it means there's a uniformity in how you treat the lines.
Now think about generating code. Something like (pseudo-code):
output("int a[] = {"); for (int i = 0; i < items.length; i++) { output("%s, ", items[i]); } output("};");No need to worry about whether the current item you're writing out is the first or the last. Much simpler.
