The package-merge algorithm is an O(nL)-time algorithm for finding an optimal length-limited Huffman code for a given distribution on a given alphabet of size n, where no code word is longer than L. It is a greedy algorithm , and a generalization of Huffman's original algorithm .
In the Apple macOS operating system, a package is a file system directory that is normally displayed to the user by the Finder as if it were a single file. [1] Such a directory may be the top-level of a directory tree of objects stored as files, or it may be other archives of files or objects for various purposes, such as installer packages, or backup archives.
Prior to Mac OS X Leopard, installer packages were implemented as Mac OS X packages. [94] These packages were a collection of files that resided in folders with a .pkg file extension. [ 95 ] [ 96 ] In Mac OS X Leopard the software packaging method was changed to use the XAR (eXtensible ARchiver) file format; the directory tree containing the ...
At that time, package installation involved the source code being downloaded and compiled on the end user's machine. Version 2.0, released in 2011, introduced support for prebuilt binary archives; by default ports are installed using the prebuilt binary archive if available, and are built from source otherwise.
The default size of an extent record in the classic Mac OS is 1 KB and 4 KB in macOS. The Attributes File is a new B-tree in HFS Plus that does not have a corresponding structure in HFS. The Attributes File can store three different types of 4 KB records: Inline Data Attribute records, Fork Data Attribute records and Extension Attribute records.
Programming languages that support arbitrary precision computations, either built-in, or in the standard library of the language: Ada: the upcoming Ada 202x revision adds the Ada.Numerics.Big_Numbers.Big_Integers and Ada.Numerics.Big_Numbers.Big_Reals packages to the standard library, providing arbitrary precision integers and real numbers.
There is an ongoing effort called the Package Manager Specification project (PMS), [7] which aims to standardise and document the behaviour of Portage, allowing the ebuild tree and Gentoo system packages to be used with alternative package managers such as Paludis and pkgcore. Its goal is to specify the exact set of features and behaviour of ...
