The new boost is out!

Boost 1.64.0 is released

From the article:

New Libraries

Process:
Process library by Klemens D. Morgenstern, that provides cross platorm ways to allows you to:

• create child processes
• setup streams for child processes
• communicate with child processes through streams (synchronously or asynchronously)
• wait for processes to exit (synchronously or asynchronously)
• terminate processes

Broken feature:

GitHub #67: "group.wait() does not return".

Updated Libraries

Any:

• Suppressed false warnings about returning reference to temporary
• boost::addressof is now used instead of directly taking the address #12615
• Headers are not included using double quotes any more #12053
• CI tests now run with address, leak, and undefined sanitizers
• Added more test

Atomic:

• Fixed possible incorrect code generation in 64-bit atomic operations on 32-bit x86 with gcc versions older than 4.7 and compatible compilers.

Config:

• Added BOOST_NO_CXX11_SFINAE_EXPR defect detection.

C++ Jobs and Predictions -- Bartlomiej Filipek

By bfilipek | Apr 19, 2017 12:09 AM | Tags: community

Is C++ job market falling or growing? Since billions of lines of code are already written it's not possible to disappear in a second. So what's the current state and the future?

C++ Jobs and Predictions

by Bartlomiej Filipek

From the article:

... if you like this area you'll be able to find a C++ job anyway. I hope C++20 will add another good reason to stick with C++ and even move from other languages... but we need to wait a few years to see it happening.

Quick Q: Are the experimental features of modern C++ reliable for long-term projects?

By Adrien Hamelin | Apr 14, 2017 01:03 AM | Tags: community basics

Quick A: No

Recently on SO:

Are the experimental features of modern C++ reliable for long-term projects?

Is it guaranteed that all compliant compilers have the same experimental features?

No, experimental features are optional.

Are experimental features prone to big changes that make them unreliable?

Yes, the C++ committee might even decide to abandon a feature or in the process of standardization a defect might come up that would force a feature to change.

Generally, it's not a good idea to depend on experimental features. Experimental features are exactly what the word says (i.e., to experiment with).

A new useful feature in Qt:

Disabling narrowing conversions in signal/slot connections

by Giuseppe D'Angelo

From the article:

A small new feature that I have added to Qt 5.8 is the possibility of disabling narrowing conversions in the new-style QObject::connect statement. In this short blog post I would like to share with you why I thought this was useful and therefore implemented it...

Making things do stuff – Part 1--Glennan Carnie

C++ for embedded too!

Making things do stuff – Part 1

by Glennan Carnie

From the article:

C has long been the language of choice for smaller, microcontroller-based embedded systems; particularly for close-to-the-metal hardware manipulation.

C++ was originally conceived with a bias towards systems programming; performance and efficiency being key design highlights.  Traditionally, many of the advancements in compiler technology, optimisation, etc., had centred around generating code for PC-like platforms (Linux, Windows, etc).  In the last few years C++ compiler support for microcontroller targets has advanced dramatically, to the point where Modern C++ is a increasingly attractive language for embedded systems development...
