This duct type is the Python native extension api (not python ctypes) which allows creating native code modules (aka libraries) in C or C++ and creating wrappers to existing C or C++ libraries. This escape hatch that enables offloading cpu-

Hardly it will fully replace C++ due to the pervasiveness of the language on many domains and also due to the C++ ecosystem that encompasses system programming; embedded systems; games and so on. For instance, the C++ ecosystem still outmat

That is not too hard if one uses Pybind11 C++ library, which allows creating native code Python modules (shared libraries) in a simple and declarative manner. Other library that can be used with Pybind11 is Eigen for linear algebra that can

Matlab and its Simulink extension, which is widely used for designing control system has a feature for generating C code that can be deployed without Matlab runtime. Someone with knowledge of code generation and compilers could take this Ma

Unlike Rust and Golang. C++ has long history and baggage, thus there is no standard tooling for C++ such as building systems and package managers. In the past, every operating system had its own set of preferred tooling for C and C++, on Li

If you use QEMU plus KVM (Kernel Virtual Machine), you can say goodbye to dual boot as the virtual machine is run with near native performance. For playing windows-only games, the solution is GPU passthrough, which allows allocating a GPU f

C++ could adopt the UFCS universal-function-call feature of D-language that allows any ordinary free function to be called as if they were methods, without any special kind of type annotation. One of major advantages of UFCS is that it enha

Most embedded graphical Linux applications don't use X (X Windows System), instead they use framebuffer directly or any library such as Qt Widgets or QtQuick/Qml that draws on top of the framebuffer device file. So, there is no ne

Well, most of QT libraries are LGPL, therefore you don't need a commercial license for a non open source project as long as you dynamic link against the Qt library and don't static link against it. On Windows it is easy to pack a

The lack of standard ABI makes harder to call C++ from foreign-function interfaces or from dlopen/LoadLibrary dynamic loading functions. It lack of ABI also does not allow linking against object-codes built by the other compilers or ev

Those large amount bindings are possible due to the GTK be written in C, which allows creating binding to GTK via FFI - foreign function interface or native interface (borrowing the term from java JNI). Creating bindings to QT is harder bec

Well, besides ARM, there is also MIPS core or ISA that IC makes can also buy a license and embed into their products in the same fashion as ARM.

You don't need to teach docker. All you need is providing a docker image with everything pre-installed such as Julia, R language, Python, numpy, pandas, Tensorflow and maybe Vscode. And also any Linux distribution, then one can just ty

Besides the dependency management, another major problem of Python is the deployment. Although Docker is not a dependency management tool, it can be used as a deployment tool which encapsulates the application to be deployed, python runtime

On Windows, MSVC does not provide guarantees that it will not keep the ABI on new releases. The drawback of using the Qt provided by the Linux distribution, is the reproducibility of the development environment as it is not possible to cont

Python dependency management of packages using C or C++ behind the scenes is really problematic and sometimes, the installation may fail. In this case, a solution is to use Conda or mini conda which provide many pre-compiled packages and al

The trouble of distributing Qt in binary format is the C++ non standard ABI problem. Qt has to be compiled for every possible compiler and many different versions of the same compiler, in order to avoid linking error. On Unices, most compil

In the case of SpaceX, it seems that they use embedded Linux and C++ with x86 processors, same as standard PC processors. A reason for using embedded linux is that, it allows using standard C++ or even scripting languages for controlling th
