Reasons Why You Should Keep Learning C/C++

Many beginners and students find C/C++ language hard to master because it requires them to think a lot. There are many language-specific quirks, especially in C++, that give students and programmers a hard time. It also has a steep learning curve and is rarely used in modern application development, which prompts many people to give … Continue reading Reasons Why You Should Keep Learning C/C++

Now that we’re clear on the Compiler-generated Functions, the Rule of Three and the Rule of Five, let’s put this to use to reflect on how to use the “= default” feature to have expressive and correct code. Indeed, C++11 added the possibility to require from the compiler that it write a default implementation for these […]

How the Boeing 737 Max Disaster Looks to a Software Developer - IEEE Spectrum
▻https://spectrum.ieee.org/aerospace/aviation/how-the-boeing-737-max-disaster-looks-to-a-software-developer

That’s because the major selling point of the 737 Max is that it is just a 737, and any pilot who has flown other 737s can fly a 737 Max without expensive training, without recertification, without another type of rating. Airlines—Southwest is a prominent example—tend to go for one “standard” airplane. They want to have one airplane that all their pilots can fly because that makes both pilots and airplanes fungible, maximizing flexibility and minimizing costs.

It all comes down to money, and in this case, MCAS was the way for both Boeing and its customers to keep the money flowing in the right direction. The necessity to insist that the 737 Max was no different in flying characteristics, no different in systems, from any other 737 was the key to the 737 Max’s fleet fungibility. That’s probably also the reason why the documentation about the MCAS system was kept on the down-low.

Put in a change with too much visibility, particularly a change to the aircraft’s operating handbook or to pilot training, and someone—probably a pilot—would have piped up and said, “Hey. This doesn’t look like a 737 anymore.” And then the money would flow the wrong way.

Report from the February 2019 ISO C++ meeting (Core Language working group) by Jason Merrill

From the article:

The February 2019 ISO C++ meeting was held in Kailua-Kona, Hawaii. As usual, Red Hat sent three developers to the meeting: I attended in the Core Language working group, Jonathan Wakely in Library, and Thomas Rodgers in SG1 (parallelism and concurrency). The meeting went smoothly, although there was significant uncertainty at the beginning where we would end up. In the end, Modules and Coroutines were accepted into the C++20 draft, so now we have our work cut out for us nailing down the remaining loose corners. Here ar highlights from the (...)

There’s little argument that open source has transformed our world. As a developer, I cannot recall a single day in the last few years where I did not rely on open source software. I’m not the exception. The majority of software engineers today rely on open source daily in their professional lives.For one, open source is dominating developer infrastructure. From operating systems (Linux in the cloud) to databases (MySQL, MongoDB, Redis) to programming languages themselves (JavaScript, Python, Java, C, PHP). It’s not just developers, it’s consumers as well. From what they run on their phones (Android) to how they access the web (Chrome, Firefox).The motivation is clear. Open source is good for humanity. It is making technology more accessible and open — anyone can build anything.Open source (...)

How to Emulate the Spaceship Operator Before C++20 with CRTP—Henrik Sjöström

How to Emulate the Spaceship Operator Before C++20 with CRTP by Henrik Sjöström

From the article:

Making a class comparable is usually something of a chore. In C++20 we’ll get the “three-way comparison operator” or informally spaceship operator <=>. It will allow the compiler to create comparison operators when we want a simple lexicographical comparison and when we have a more complex comparison we only need to implement a single operator to be able to do all comparisons...

Abseil Support for CMake
▻https://abseil.io/blog/20190402-cmake-support

By Jon Cohen, Abseil Engineer

CMake is a popular tool used to build multi-platform C++ projects. Abseil has had unofficial CMake support for some time, but support has never been as robust as that for Bazel. We are happy to announce that Abseil now fully supports the CMake build system.

Abseil supports CMake through the add_subdirectory command for full source inclusion, or by local installation into your project. Future Abseil LTS releases will be supported for installation in system-wide locations (such as /usr/local, CMake’s default install location).

We hope that this support will make it easier for users to adopt Abseil and for package managers to successfully and easily package Abseil.

In regard to this, a few seconds are needed to spend at the below-given graph:One of the major advantages of its being easy is that it is very easy to interface with other languages as well particularly with C and C++.
