Computer Scientist
A computer scientist is a scientist who specializes in the academic study of computer science. Computer scientists typically work on the theoretical side of computation. Although computer scientists can also focus their work and research on specific areas (such as algorithm and data structure development and design, software engineering, information theory, database theory, theoretical computer science, numerical analysis, programming language theory, compiler, computer graphics, computer vision, robotics, computer architecture, operating system), their foundation is the theoretical study of computing from which these other fields derive. A primary goal of computer scientists is to develop or validate models, often mathematical, to describe the properties of computational systems (Processor (computing), processors, programs, computers interacting with people, computers interacting with other computers, etc.) with an overall objective of discovering designs that yield useful ...

Recent changes to these articles are listed on Special:RecentChangesLinked/Living people. Organization: This category should not be sub-categorized. Entries are generally sorted by family name In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several give ....

FreeBSD People
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system. FreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties such as GNU for system software. The FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The project includes a security team overseeing all software shipped in the base distribution. Third-party applications may be installed using the pkg package management system or from source via FreeBSD Ports. The project is supported and promoted by the FreeBSD Foundation. Much of ...

BSD People
The Berkeley Software Distribution (BSD), also known as Berkeley Unix or BSD Unix, is a discontinued Unix operating system developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley, beginning in 1978. It began as an improved derivative of AT&T's original Unix that was developed at Bell Labs, based on the source code but over time diverging into its own code. BSD would become a pioneer in the advancement of Unix and computing. BSD's development was begun initially by Bill Joy, who added virtual memory capability to Unix running on a VAX-11 computer. In the 1980s, BSD was widely adopted by workstation vendors in the form of proprietary Unix distributions such as DEC Ultrix and Sun Microsystems SunOS due to its permissive licensing and familiarity to many technology company founders and engineers. It also became the most popular Unix at universities, where it was used for the study of operating systems. BSD was sponsored by D ...

Toy Story
''Toy Story'' is a 1995 American animated adventure comedy film produced by Pixar Animation Studios for Walt Disney Pictures. It is the first installment in the Toy Story (franchise), ''Toy Story'' franchise and the Firsts in animation, first entirely computer-animated feature film, as well as the first feature film from Pixar. The film was directed by John Lasseter, written by Joss Whedon, Andrew Stanton, Joel Cohen (writer), Joel Cohen, and Alec Sokolow based on a story by Lasseter, Stanton, Pete Docter, and Joe Ranft, produced by Bonnie Arnold and Ralph Guggenheim, and features the voices of Tom Hanks, Tim Allen, Annie Potts, John Ratzenberger, Don Rickles, Wallace Shawn, and Jim Varney. Taking place in a world where toys come to life when humans are not present, the plot of ''Toy Story'' focuses on the relationship between an old-fashioned pullstring cowboy doll named Sheriff Woody, Woody and a modern space cadet action figure, Buzz Lightyear, as Woody develops jealousy t ...

Tin Toy
A tin toy, or tin lithograph toy, is a mechanical toy made out of tinplate and colorfully painted by chromolithography to resemble primarily a character or vehicle. History Tinplate was used in the manufacture of toys beginning in the mid-19th century. The invention of sheet metal stamping machines in 1815 allowed for the mass production of inexpensive toys. Tin toys were made from thin sheets of steel plated with tin, hence the name ''tinplate''. Tin toys were a cheap and durable substitute for wooden toys. The toys were originally assembled and painted by hand. Spring-activated tin toys originated in Germany in the 1850s. In the late 1880s offset lithography was used to print designs on tinplate. After the colorful designs were printed on the metal, they were formed by dies and assembled with small tabs. The lightweight nature of the toys allowed them to be shipped less expensively and easier than the heavier cast iron toys. Germany was the major producer of tin toys in the ...

Luxo Jr
''Luxo Jr.'' is a 1986 American animated short film produced and released by Pixar. Written and directed by John Lasseter, the two-minute short film revolves around one larger and one smaller desk lamp. The larger lamp, named Luxo Sr., looks on while the smaller, "younger" Luxo Jr. plays exuberantly with a ball to the extent that it accidentally deflates. ''Luxo Jr.'' was Pixar's first animation after Ed Catmull and John Lasseter left the Lucasfilm Computer Division. The film is the source of Luxo Jr., the mascot of Pixar. Lasseter aimed to finish the short film for the 1986 SIGGRAPH, an annual computer graphics conference attended by thousands of industry professionals. The film would come from his experiments with modeling his Luxo lamp. Lasseter worked to improve the story within the allotted two minutes. In animation, the film demonstrates the use of shadow maps within the rendering software. Lasseter applied the classic animation principles popularized by Disney's Nin ...

Softimage 3D
Softimage 3D, stylized as Softimage, 3D, is a discontinued high-end 3D graphics application developed by Softimage, which was used predominantly in the film, broadcasting, gaming, and advertising industries for the production of 3D animation. It was superseded by Softimage XSI in 2000. History In 1986, National Film Board of Canada filmmaker Daniel Langlois, in partnership with software engineers Richard Mercille and Laurent Lauzon, began developing an integrated 3D modeling, animation, and rendering package with a graphical interface targeted at visual artists. The software was initially demonstrated at SIGGRAPH in 1988 and was released for Silicon Graphics workstations the following year as the Softimage Creative Environment. Softimage Creative Environment was adopted by major visual effects studios like Industrial Light & Magic and Digital Domain for use in their production pipelines, which also typically included software from Alias Research, Big Idea Productions, Kroyer ...
