  2. Spectral layout - Wikipedia

    en.wikipedia.org/wiki/Spectral_layout

    Spectral layout is a class of algorithm for drawing graphs. The layout uses the eigenvectors of a matrix, such as the Laplace matrix of the graph, as Cartesian coordinates of the graph's vertices. The idea of the layout is to compute the two largest (or smallest) eigenvalues and corresponding eigenvectors of the Laplacian matrix of the graph ...

  3. Linux color management - Wikipedia

    Color profile viewer on KDE Plasma 5, showing an ICC color profile. Linux color management has the same goal as the color management systems (CMS) for other operating systems, which is to achieve the best possible color reproduction throughout an imaging workflow from its source (camera, video, scanner, etc.), through imaging software (Digikam, darktable, RawTherapee, GIMP, Krita, Scribus, etc ...

  4. IRAF - Wikipedia

    en.wikipedia.org/wiki/IRAF

    IRAF was designed cross-platform, supporting VMS and UNIX-like operating systems. Use on Microsoft Windows was made possible by Cygwin in earlier versions, and can be today done with the Windows Subsystem for Linux. Today, it is primarily used on macOS and Linux. IRAF commands (known as tasks) are organized into package structures.

  5. List of POSIX commands - Wikipedia

    en.wikipedia.org/wiki/List_of_POSIX_commands

    This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.

  6. NetworkX - Wikipedia

    en.wikipedia.org/wiki/NetworkX

    The Spectral layout is based on the spectral properties of the graph's adjacency matrix. It uses the eigenvalues and eigenvectors of the adjacency matrix to position nodes in a low-dimensional space. Spectral layout tends to emphasize the global structure of the graph, making it useful for identifying clusters and communities. [15]

  7. Linux kernel interfaces - Wikipedia

    en.wikipedia.org/wiki/Linux_kernel_interfaces

    The Linux API is composed out of the system call interface of the Linux kernel, the GNU C Library (by GNU), libcgroup, [1] libdrm, libalsa and libevdev [2] (by freedesktop.org). Linux API vs. POSIX API. The Linux API includes the kernel–user space API, which allows code in user space to access system resources and services of the Linux kernel ...

  8. OpenRC - Wikipedia

    en.wikipedia.org/wiki/OpenRC

    OpenRC is a dependency-based init system for Unix-like computer operating systems.It was created by Roy Marples, a NetBSD developer who was also active in the Gentoo project. [3] [4] It became more broadly adopted as an init system outside of Gentoo following the decision by some Linux distributions not to adopt systemd.

  9. man page - Wikipedia

    en.wikipedia.org/wiki/Man_page

    The modern descendants of 4.4BSD also distribute man pages as one of the primary forms of system documentation (having replaced the old -man macros with the newer -mdoc). There was a hidden Easter egg in the man-db version of the man command that would cause the command to return "gimme gimme gimme" when run at 00:30 (a reference to the ABBA ...
