POSIXcentric

POSIXcentric refers to a design philosophy or approach to software development that prioritizes adherence to the Portable Operating System Interface (POSIX) standards. This philosophy emphasizes writing software that is highly portable across different Unix-like operating systems, such as Linux, macOS, and BSD variants, by relying heavily on POSIX-defined system calls, libraries, and utilities. Developers following a POSIXcentric approach aim to minimize platform-specific code, thereby simplifying cross-platform compatibility and maintenance.

The core idea behind POSIXcentric development is to abstract away the nuances of individual operating systems by leveraging the common ground provided by POSIX. This often involves using standard C libraries, POSIX threads (pthreads), and standard file I/O operations. While this approach promotes portability, it can sometimes limit the ability to take full advantage of unique features or optimizations offered by a specific operating system. Consequently, the trade-off between portability and platform-specific performance is a key consideration for developers adopting this philosophy.
