JFS may refer to:
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.
JFS (formerly known as the Jews' Free School and later Jewish Free School) is a Jewish mixed comprehensive school in Kenton, north London, England. At one time it was the largest Jewish school in Europe, with more than 4,000 pupils.
JFS operates the house system and has four houses for organisational purposes. Students must wear a tie with stripes in their house colour, e.g. blue for Brodetski students.
Both Brodetsky and Zangwill were former students, Angel was the first headmaster and Weizmann, who has several links to the school, was the first president of the state of Israel.
Students are split into their respective houses for most classes in Years 7, 8 and 9 as well as inter-house competitions, such as football and basketball.
Reality is the state of things as they actually exist, rather than as they may appear or might be imagined. In a wider definition, reality includes everything that is and has been, whether or not it is observable or comprehensible. A still broader definition includes everything that has existed, exists, or will exist.
Philosophers, mathematicians, and other ancient and modern thinkers, such as Aristotle, Plato, Frege, Wittgenstein, and Russell, have made a distinction between thought corresponding to reality, coherent abstractions (thoughts of things that are imaginable but not real), and that which cannot even be rationally thought. By contrast existence is often restricted solely to that which has physical existence or has a direct basis in it in the way that thoughts do in the brain.
Reality is often contrasted with what is imaginary, delusional, (only) in the mind, dreams, what is false, what is fictional, or what is abstract. At the same time, what is abstract plays a role both in everyday life and in academic research. For instance, causality, virtue, life and distributive justice are abstract concepts that can be difficult to define, but they are only rarely equated with pure delusions. Both the existence and reality of abstractions are in dispute: one extreme position regards them as mere words; another position regards them as higher truths than less abstract concepts. This disagreement is the basis of the philosophical problem of universals.
Reality is a 1974 album by jazz bassist Monk Montgomery, one of his four solo albums. It was released on Philadelphia International Records.
