Xapian is a free and open-source probabilistic information retrieval library, released under the GNU General Public License (GPL). [2] It is a full-text search engine library for programmers.
It is written in C++, with bindings to allow use from Perl, Python (2 and 3), PHP (5 and 7), Java, Tcl, C#, Ruby, Lua, Erlang, Node.js and R. [1] [3] Xapian is highly portable and runs on Linux, OS X, FreeBSD, NetBSD, OpenBSD, Solaris, HP-UX, AIX, Windows, OS/2 [4] [2] and Hurd, [5] [6] as well as Tru64.[ citation needed ] Xapian grew out of the Muscat search engine, written by Dr. Martin F. Porter at the University of Cambridge. [7] The first official release of Xapian was version 0.5.0 on September 20, 2002. [8]
Xapian allows developers to add advanced indexing and search facilities to their own applications. Organisations and projects using Xapian include the Library of the University of Cologne, Debian, Die Zeit, MoinMoin, and One Laptop per Child. [9]
Debian, also known as Debian GNU/Linux, is a Linux distribution composed of free and open-source software, developed by the community-supported Debian Project, which was established by Ian Murdock on August 16, 1993. The first version of Debian (0.01) was released on September 15, 1993, and its first stable version (1.1) was released on June 17, 1996. The Debian Stable branch is the most popular edition for personal computers and servers. Debian is also the basis for many other distributions, most notably Ubuntu.
GNU is an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems. The use of the completed GNU tools led to the family of operating systems popularly known as Linux. Most of GNU is licensed under the GNU Project's own General Public License (GPL).
Irssi is an IRC client program for Linux, FreeBSD, macOS and Microsoft Windows. It was originally written by Timo Sirainen, and released under the terms of the GNU GPL-2.0-or-later in January 1999.
Information retrieval (IR) in computing and information science is the process of obtaining information system resources that are relevant to an information need from a collection of those resources. Searches can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds.
Advanced package tool, or APT, is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian, and Debian-based Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
dpkg is the software at the base of the package management system in the free operating system Debian and its numerous derivatives. dpkg
is used to install, remove, and provide information about .deb packages.
Portage is a package management system originally created for and used by Gentoo Linux and also by ChromeOS, Calculate, Sabayon, and Funtoo Linux among others. Portage is based on the concept of ports collections. Gentoo is sometimes referred to as a meta-distribution due to the extreme flexibility of Portage, which makes it operating-system-independent. The Gentoo/Alt project was concerned with using Portage to manage other operating systems, such as BSDs, macOS and Solaris. The most notable of these implementations is the Gentoo/FreeBSD project.
deb is the format, as well as extension of the software package format for the Debian Linux distribution and its derivatives.
Within the free software and the open-source software communities there is controversy over whether to refer to computer operating systems that use a combination of GNU software and the Linux kernel as "GNU/Linux" or "Linux" systems.
Free and Open source Software Developers' European Meeting (FOSDEM) is a non-commercial, volunteer-organized European event centered on free and open-source software development. It is aimed at developers and anyone interested in the free and open-source software movement. It aims to enable developers to meet and to promote the awareness and use of free and open-source software.
Technical variations of Linux distributions include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by historical reasons. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of packages available.
gtkmm is the official C++ interface for the popular GUI library GTK. gtkmm is free software distributed under the GNU Lesser General Public License (LGPL).
GNU variants are operating systems based upon the GNU operating system. According to the GNU project and others, these also include most operating systems using the Linux kernel and a few others using BSD-based kernels.
Strigi was a file indexing and file search framework adopted by KDE SC. Strigi was initiated by Jos van den Oever. Strigi's goals are to be fast, use a small amount of RAM, and use flexible backends and plug-ins. A benchmark as of January 2007 showed that Strigi is faster and uses less memory than other search systems, but it lacks many of their features. Like most desktop search systems, Strigi can extract information from files, such as the length of an audio clip, the contents of a document, or the resolution of a picture; plugins determine what filetypes it is capable of handling. Strigi uses its own Jstream system which allows for deep indexing of files. Strigi is accessible via Konqueror, or by clicking on its icon, after adding it to KDE's Kicker or GNOME Panel. The graphical user interface (GUI) is named Strigiclient.
MoinMoin is a wiki engine implemented in Python, initially based on the PikiPiki wiki engine. Its name is a play on the North German greeting Moin, repeated as in WikiWiki. The MoinMoin code is licensed under the GNU General Public License v2, or any later version.
WeeChat is a free and open-source Internet Relay Chat client that is designed to be light and fast. It is released under the terms of the GNU GPL-3.0-or-later and has been developed since 2003.
Arch Hurd is an operating system based on Arch Linux, but uses the GNU Hurd kernel instead of the Linux kernel.
OpenMediaVault (OMV) is a free Linux distribution designed for network-attached storage (NAS). The project's lead developer is Volker Theile, who instituted it in 2009. OMV is based on the Debian operating system, and is licensed through the GNU General Public License v3.
