Strigi
Strigi was a file indexing and file search framework (see desktop search) 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. (In GNOME desktop, it is called the Deskbar applet.) The graphical user interface (GUI) is named Strigiclient. It was replaced with Recoll in KDE5 Plasma desktop environment. Features * ...

NEPOMUK (framework)
NEPOMUK (Networked Environment for Personal, Ontology-based Management of Unified Knowledge) is an open-source software specification that is concerned with the development of a social semantic desktop that enriches and interconnects data from different desktop applications using semantic metadata stored as Resource Description Framework, RDF. Between 2006 and 2008 it was funded by a European Union research project of the same name that grouped together industrial and academic actors to develop various Semantic Desktop technologies. Implementations Three active implementations of NEPOMUK exist: A C++/KDE-based variant, a Java (programming language), Java-based variant, and a commercial version. More versions were created during the EU project between 2006 and 2008, some active beyond the project. KDE ''NEPOMUK-KDE'' was originally featured as one of the newer technologies in KDE Software Compilation 4. It used Soprano (KDE), Soprano as the main RDF data storage and parsing lib ...

KDE Software Compilation
The KDE Software Compilation (KDE SC) was an umbrella term for the desktop environment plus a range of included applications produced by KDE. From its 1.0 release in July 1998 until the release of version 4.4 in February 2010, the Software Compilation was simply known as KDE, which stood for K Desktop Environment until the rebrand. The then called KDE SC was used from 4.4 onward until the final release 4.14 in July 2014. It consisted of the KDE Plasma 4 desktop and those KDE applications, whose development teams chose to follow the Software Compilation's release schedule. After that, the KDE SC was split into three separate product entities: KDE Plasma, KDE Frameworks and KDE Applications, each with their own independent release schedules. History Origins KDE was founded in 1996 by Matthias Ettrich, who was then a student at the University of Tübingen. At the time, he was troubled by certain aspects of the Unix desktop. Among his qualms was that none of the applications looked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SHA-1
In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographically broken but still widely used hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits. It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard. Since 2005, SHA-1 has not been considered secure against well-funded opponents; as of 2010 many organizations have recommended its replacement. NIST formally deprecated use of SHA-1 in 2011 and disallowed its use for digital signatures in 2013, and declared that it should be phased out by 2030. , chosen-prefix attacks against SHA-1 are practical. As such, it is recommended to remove SHA-1 from products as soon as possible and instead use SHA-2 or SHA-3. Replacing SHA-1 is urgent where it is used for digital signatures. All major web browser vendors ceased acceptance of SHA-1 SSL certificates in 2017. In February ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inotify
inotify (inode notify) is a Linux kernel subsystem created by John McCutchan, which monitors changes to the filesystem, and reports those changes to applications. It can be used to automatically update directory views, reload configuration files, log changes, backup, synchronize, and upload. The ''inotifywait'' and ''inotifywatch'' commands (maintained by Eric Curtin as part of the inotify-tools project) allow using the inotify subsystem from the command line. One major use is in desktop search utilities like Beagle, where its functionality permits reindexing of changed files without scanning the filesystem for changes every few minutes, which would be very inefficient. inotify replaced an earlier facility, dnotify, which had similar goals. It was merged into the Linux kernel mainline in kernel version 2.6.13, released on August 29, 2005; later kernel versions included further improvements. The required library interfaces were added into the GNU C Library (glibc) in its version 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xapian
Xapian is a free and open-source probabilistic information retrieval library, released under the GNU General Public License (GPL). 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. Xapian is highly portable and runs on Linux, OS X, FreeBSD, NetBSD, OpenBSD, Solaris, HP-UX, AIX, Windows, OS/2 and Hurd, as well as Tru64. Xapian grew out of the Muscat search engine, written by Dr. Martin F. Porter at the University of Cambridge. The first official release of Xapian was version 0.5.0 on September 20, 2002. 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. Features * Supports Unicode 9.0 (including codepoints beyond the BMP) and stores index ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SQLite
SQLite (, ) is a database engine written in the C programming language. It is not a standalone app; rather, it is a library that software developers embed in their apps. As such, it belongs to the family of embedded databases. It is the most widely deployed database engine, as it is used by several of the top web browsers, operating systems, mobile phones, and other embedded systems. Many programming languages have bindings to the SQLite library. It generally follows PostgreSQL syntax, but does not enforce type checking by default. This means that one can, for example, insert a string into a column defined as an integer. History D. Richard Hipp designed SQLite in the spring of 2000 while working for General Dynamics on contract with the United States Navy. Hipp was designing software used for a damage-control system aboard guided-missile destroyers, which originally used HP-UX with an IBM Informix database back-end. SQLite began as a Tcl extension. In August 2000, versio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucene
Apache Lucene is a free and open-source search engine software library, originally written in Java by Doug Cutting. It is supported by the Apache Software Foundation and is released under the Apache Software License. Lucene is widely used as a standard foundation for non-research search applications. Lucene has been ported to other programming languages including Object Pascal, Perl, C#, C++, Python, Ruby and PHP. History Doug Cutting originally wrote Lucene in 1999. Lucene was his fifth search engine, having previously written two while at Xerox PARC, one at Apple, and a fourth at Excite. It was initially available for download from its home at the SourceForge web site. It joined the Apache Software Foundation's Jakarta family of open-source Java products in September 2001 and became its own top-level Apache project in February 2005. The name Lucene is Doug Cutting's wife's middle name and her maternal grandmother's first name. Lucene formerly included a number of sub-projec ...

D-Bus
In computing, D-Bus (short for "Desktop Bus") is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. D-Bus was developed as part of the freedesktop.org project, initiated by Havoc Pennington from Red Hat to standardize services provided by Linux desktop environments such as GNOME and KDE. The freedesktop.org project also developed a free and open-source software library called libdbus, as a reference implementation of the specification. This library should not be confused with D-Bus itself, as other implementations of the D-Bus specification also exist, such as GDBus (GNOME), QtDBus ( Qt/KDE), dbus-java and sd-bus (part of systemd). Overview D-Bus is an inter-process communication (IPC) mechanism initially designed to replace the software component communications systems used by the GNOME and KDE Linux desktop environments (CORBA and DCOP respectively). The components of these desktop environ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenDocument
The Open Document Format for Office Applications (ODF), also known as OpenDocument, is an open file format for word processing documents, spreadsheets, presentations and graphics and using ZIP-compressed XML files. It was developed with the aim of providing an open, XML-based file format specification for office applications. It is also the default format for documents in typical Linux distributions. The standard is developed and maintained by a technical committee in the Organization for the Advancement of Structured Information Standards (OASIS) consortium. It was based on the Sun Microsystems specification for OpenOffice.org XML, the default format for OpenOffice.org and LibreOffice. It was originally developed for StarOffice "to provide an open standard for office documents." In addition to being an OASIS standard, it is published as an ISO/IEC international standard ISO/IEC 26300 Open Document Format for Office Applications (OpenDocument). In 2021 the current ve ...
