The project uses ninja as the primary backend buildsystem, but can also use Visual Studio or Xcode backends. Meson's support for Fortran and Cython was improved to help various scientific projects in their switch from setuptools to Meson, for example SciPy. [7] Meson can be used as a PEP517 backend to build Python wheels, via the meson-python ...
When numerous instances of Duff's device were removed from the XFree86 Server in version 4.0, there was an improvement in performance and a noticeable reduction in size of the executable. [7] Therefore, before applying any program optimization , it should be benchmarked or its compiled output should be explored, to verify that it performs as ...
Switch expressions are introduced in Java SE 12, 19 March 2019, as a preview feature. Here a whole switch expression can be used to return a value. There is also a new form of case label, case L-> where the right-hand-side is a single expression. This also prevents fall through and requires that cases are exhaustive.
The web server or database management system also varies. LEMP is a version where Apache has been replaced with the more lightweight web server Nginx.

An open transition transfer switch is also called a break-before-make transfer switch. A break-before-make transfer switch breaks contact with one source of power before it makes contact with another. It prevents backfeeding from an emergency generator back into the utility line, for example. [1] One example is an open transition automatic ...
In particular, the POSIX specification and the Linux man page signal (7) require that all system functions directly or indirectly called from a signal function are async-signal safe. [6] [7] The signal-safety(7) man page gives a list of such async-signal safe system functions (practically the system calls), otherwise it is an undefined behavior ...
In computer science, read-copy-update (RCU) is a synchronization mechanism that avoids the use of lock primitives while multiple threads concurrently read and update elements that are linked through pointers and that belong to shared data structures (e.g., linked lists, trees, hash tables).
