JFS (file system)
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.
History
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.
Veritas File 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).
History
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.
Brainstorm (2000 film)
Brainstorm (Portuguese: Bicho de Sete Cabeças) is a 2000 drama film directed by Laís Bodanzky based on the autobiographical book Canto dos Malditos by Austregésilo Carrano Bueno. The film was made through a partnership between Brazilian and Italian studios and starred Rodrigo Santoro, Othon Bastos and Cassia Kiss. The film tells the story of Neto, a young man who is admitted to a psychiatric hospital after his father discovers he is a user of marijuana. There, Neto is submitted to abuse. In addition to abuse by psychiatric hospitals, the film deals with the issues of drugs and relationships between fathers and sons.
Bodanzky read Carrano's book in 1996 and, impressed by the theme, assigned Luiz Bolognesi to adapt it into a film and transpose its setting from the 1970s to the 1990s. In addition to keeping the film in the present, Bodanzky chose to make it a documentary-style film to create greater impact on the viewer. Bolognesi began writing in 1997 with the freedom to make changes to the original story. The film was shot in early 2000 in São Paulo, and was edited and finalized in Italy.
Brainstorm (TV series)
Brainstorm was a British comedy quiz programme about science. It originally aired on BBC1 for one series in 1988, hosted by Kenny Everett and co-hosted by Cleo Rocos.

Brainstorm (board game)
Brainstorm is a quiz-style board game.
Brainstorm is a game for two to four players. The game uses a pile of question cards and a board. The board takes the form of a single line of squares from start to finish, and each player uses a coloured brain as his/her game counter. All counters start from the beginning square.
On each turn, the neighbour of the player in question is acting as the judge. The judge draws a question card from the pile. The question takes the form of a topic, and the player's task is to mention as many things fitting under that topic as possible, within one minute. After the time is up, the judge checks the player's answers against a checklist of ten answers on the question card. Every answer found on the checklist is worth one point. Some cards have italicised answers, these are worth two points each. The player's counter moves as many places forward as the player has scored points. Some places have special instructions to follow.
The first player to reach the finishing square wins.
