JFS may refer to:
Journaled File System or JFS is a 64-bit journaling file system created by IBM. There are versions for AIX, eComStation, OS/2, and Linux operating systems. The latter is available as free software under the terms of the GNU General Public License (GPL). HP-UX has another, different filesystem named JFS that is actually an OEM version of Veritas Software's VxFS.
In the AIX operating system, there exist two generations of JFS filesystem that are called JFS (JFS1) and JFS2 respectively. In the other operating systems, such as OS/2 and Linux, only the second generation exists and is called simply JFS. This should not be confused with JFS in AIX that actually refers to JFS1.
IBM introduced JFS with the initial release of AIX version 3.1 in February, 1990. This file system, now called JFS1 on AIX, had been the premier file system for AIX over the following decade and had been installed in thousands or millions of customers' AIX systems. Historically, the JFS1 file system is very closely tied to the memory manager of AIX, which is a typical design for a file system supporting only one operating system.
The VERITAS File System (or VxFS; called JFS and OnlineJFS in HP-UX) is an extent-based file system. It was originally developed by VERITAS Software. Through an OEM agreement, VxFS is used as the primary filesystem of the HP-UX operating system. With on-line defragmentation and resize support turned on via license, it is known as OnlineJFS. It is also supported on AIX, Linux, Solaris, OpenSolaris, SINIX/Reliant UNIX, UnixWare and SCO OpenServer. VxFS was originally developed for AT&T's Unix System Laboratories. VxFS is packaged as a part of the Veritas Storage Foundation (which also includes Veritas Volume Manager).
According to the vendor, it was the first commercial journaling file system. That claim can be taken in two ways, i.e., the first implementation of a journaling file system in a commercial context, or the first file system available as an unbundled product.
Dan Koren is cited as one of the original developers of VxFS. He notes in a mailing list that they "finished release 1.0 one year or so later" after starting development of VxFS under a contract with AT&T Corporation in 1990. Other sources agree that the product was first released in 1991.
Trance denotes any state of awareness or consciousness other than normal waking consciousness. Trance states may occur involuntarily and unbidden.
The term trance may be associated with hypnosis, meditation, magic, flow, and prayer. It may also be related to the earlier generic term, altered states of consciousness, which is no longer used in "consciousness studies" discourse.
Trance in its modern meaning comes from an earlier meaning of "a dazed, half-conscious or insensible condition or state of fear", via the Old French transe "fear of evil", from the Latin transīre "to cross", "pass over". This definition is now obsolete.
Wier, in his 1995 book, Trance: from magic to technology, defines a simple trance (p. 58) as a state of mind being caused by cognitive loops where a cognitive object (thoughts, images, sounds, intentional actions) repeats long enough to result in various sets of disabled cognitive functions. Wier represents all trances (which include sleep and watching television) as taking place on a dissociated trance plane where at least some cognitive functions such as volition are disabled; as is seen in what is typically termed a 'hypnotic trance'. With this definition, meditation, hypnosis, addictions and charisma are seen as being trance states. In Wier's 2007 book, The Way of Trance, he elaborates on these forms, adds ecstasy as an additional form and discusses the ethical implications of his model, including magic and government use which he terms "trance abuse".
Trance is an album by American jazz pianist and composer Steve Kuhn recorded in 1974 and released on the ECM label.
The Allmusic review by Thom Jurek awarded the album 4 stars stating "This is jazz that touches on fusion, modal, and the new spirit of the music as ECM came into the 1970s as a player. There is restlessness and calm, tempestuousness and serenity, conflict and resolution, and -- above all -- creativity and vision".
Standing Stone is Paul McCartney's second full-length release of original classical music (coming after 1991's Liverpool Oratorio) and was issued shortly after Flaming Pie's release in 1997. The world premiere performance was held at The Royal Albert Hall on 14 October 1997.
Following up on 1991's Paul McCartney's Liverpool Oratorio, the Standing Stone project was composed out of a long poem McCartney authored and was performed by the London Symphony Orchestra and conducted by Lawrence Foster at EMI's Abbey Road Studios. Unlike Liverpool Oratorio, this new project is not an operatic performance of a story, but an instrumental one, though it employs the use of a choir.
The cover for the album is actually one of the many photos taken by Linda McCartney during late 1969/early 1970 that would initially be seen on the inside gatefold cover of Paul's first album McCartney. Incidentally, this project was her husband's last release before Linda died of breast cancer on 17 April 1998, having been diagnosed almost three years earlier.
