STL Features and Fixes in VS 2017 15.8
by Billy O'Neal
From the article:
15.7 was our first feature complete C++17 library (except floating-point <charconv>), and in 15.8 we have addressed large numbers of outstanding bugs...

How to Remove Elements from a Sequence Container in C++
by Jonathan Boccara
From the article:
As part of the STL Learning Resource, we’re tackling today the STL algorithms that remove elements from a collection.
Removing an element from a C++ collection can’t be that complicated, can it?
Well, how can I put it… It has a rich complexity, let’s say.
Ok, maybe it’s a little complicated.
We will cover this topic in a series of four articles:
- How to Remove Elements from a Sequence Container (vector, string, deque, list)
- How to Remove Pointers from a Vector in C++ (co-written with Gaurav Sehgal)
- How to Remove Elements from an Associative Container (maps and sets)
- How to Remove Duplicates from an Associative Container

C++ Links #2
by Bartlomiej Filipek
From the article:
Welcome to new C++ Links - most important and useful articles, podcasts and videos that happened between 8th and 14th of September. Today you will find a link to a post about the C++ quality of life features, a video with an explanation of the difference between const and constexpr, an article that describes some of SFINAE problems and many others.

Modern C++ Features – Quality-of-Life Features
by Arne Mertz
From the article:
With the new C++ standards, we got a lot of features that feel like “quality-of-life” features. They make things easier for the programmer but do not add functionality that wasn’t already there. Except, some of those features do add functionality we couldn’t implement manually.
Some of those quality-of-life features are really exactly that. The standard often describes them as being equivalent to some alternative code we can actually type. Others are mostly quality-of-life, but there are edge cases where we can not get the effect by hand, or the feature is slightly superior to the manual implementation.
I will concentrate on core language features here, since most library features are implementable using regular C++. Only a few library features use compiler intrinsics...

Have you registered for CppCon 2018 in September? Late registration is open now.
While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2017 for you to enjoy. Here is today’s feature:
Class Template Argument Deduction: A New Abstraction
by Zhihao Yuan
Summary of the talk:
C++17 is often quoted as “just a better C++14”, suggesting that nothing is new, nothing is changing the way we program. This talk presents class template argument deduction as a counterexample, a hidden gem in the new standard.
Saves typing? A replacement for the `make` functions? If that’s your frame, then you should come to this talk. The true power of class template argument deduction is underestimated. It’s a new point of abstraction but requiring creativity, insights, and understanding about the language details to manage.
This talk will start by introducing all matters about this feature to build up sufficient background knowledge, followed by teaching how to write deduction guides by examples, and finally explain how to build abstractions using the whole feature in a top-down approach, with patterns categorized.

Lightning Talks and a Challenge
by Michael Caisse
From the article:
Lightning Talks have become an attendee favorite at CppCon. Often humorous and high energy, they provide an informal venue to teach, learn, and laugh.
If you have something to share that the C++ community might enjoy, produce a focussed 5-minute talk and register to dazzle the crowd.

New video on the CopperSpice YouTube Channel:
Constexpr Static Const
by Barbara Geller and Ansel Sermersheim
About the video:
This presentation covers constexpr and how it differs from const. We also discuss what constexpr means in practice versus what is actually required by the standard, a subject which is often misunderstood. The topic of constexpr vs preprocessor macros is also covered with suggestions for best practices.

Are you wondering how to use the Microsoft Cognitive Services with C++?
Microsoft Cognitive Services C++ SDK
by Sebastiano Galazzo
Introduction:
The project is a wrapper to use Microsoft Cognitive Services in standard C++ as is currently not supported.
The project provides full support to Computer Vision API. A wrapper to gphoto2 will provide the full control digital cameras (DSLR), getting the raw shot and making manipulations with Computer Vision API.
Available camera-ai, a working commandline example to take a picture from the camera conneced by USB and analyze by Cognitive Services.
A lot of people have a better C++ than mine, who wants to contribute is welcomed!
