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.
Insight is the understanding of a specific cause and effect in a specific context. The term insight can have several related meanings:
An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word Aha-Erlebnis. The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany.
In psychology, insight occurs when a solution to a problem presents itself quickly and without warning. It is the sudden discovery of the correct solution following incorrect attempts based on trial and error.
Insight is an American religious-themed weekly anthology series that aired in syndication from October 1960 to 1983. Produced by Paulist Productions in Los Angeles, the series presented half-hour dramas illuminating the contemporary search for meaning, freedom, and love. Insight was an anthology series, using an eclectic set of story telling forms including comedy, melodrama, and fantasy to explore moral dilemmas.
The series was created by Roman Catholic priest Ellwood E. "Bud" Kieser, the founder of Paulist Productions. A member of the Paulist Fathers, an evangelistic Catholic order of priests, he worked in the entertainment community in Hollywood as a priest-producer and occasional host, using television as a vehicle of spiritual enrichment. Many of the episodes of the series were videotaped at CBS Television City and then Metromedia Square.
The anthology format and the religious nature of the program attracted a wide variety of actors (including Jeff Hunter, Ed Asner, Jack Albertson, Beau Bridges, Carol Burnett, Ron Howard, Cindy Williams, Patty Duke, Ann Jillian, Wesley Eure, Bob Hastings, Cicely Tyson, James Doohan, Ricky Kelman, Jack Klugman, Robert Lansing, Randolph Mantooth, Walter Matthau, Deborah Winters, Bob Newhart, Bill Bixby, John Ritter, Bill Mumy, Mark Hamill, Flip Wilson, Keenan Wynn, Marty Feldman, Michael Shea, and Martin Sheen), directors (such as Marc Daniels, Arthur Hiller, Norman Lloyd, Delbert Mann, Ted Post, Jay Sandrich, and Jack Shea), and writers (Rod Serling, John T. Dugan, Lan O'Kun, and Michael Crichton) to work on the series.
Insight on the News (also called Insight) was an American conservative print and online news magazine. It was owned by News World Communications, an international media conglomerate founded by Unification Church founder Sun Myung Moon, which at the time owned The Washington Times, United Press International, and several newspapers in Japan, South Korea, Africa, and South America. Insight's reporting often resulted in journalistic controversy.
In 1991 Insight was one of the first publications to use the word "Islamophobia". In 1997 Insight reported that the administration of President Bill Clinton gave political donors rights to be buried in Arlington National Cemetery. This charge was widely repeated on talk radio and other conservative outlets; but was later denied by the United States Army, which has charge over Arlington Cemetery. Media investigations turned up the burial of M. Larry Lawrence, a former United States Ambassador to Switzerland at Arlington, which led to a congressional investigation. Republican Party members of congress searched military records and found no evidence that Lawrence was ever in the Merchant Marine. As a result, Lawrence's body was disinterred in 1997 at taxpayers' expense and moved to California. Richard Holbrooke, an assistant secretary of state, had helped obtain the rights to bury Lawrence at Arlington, and had written a letter to the White House praising Lawrence and saying that he deserved burial at the National Cemetery.
