Computer Scientist
A computer scientist is a person who is trained in the academic study of computer science. Computer scientists typically work on the theoretical side of computation, as opposed to the hardware side on which computer engineers mainly focus (although there is overlap). 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, computational complexity theory, numerical analysis, programming language theory, computer graphics, and computer vision), 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 (processors, programs, computers interacting with people, computers interacting with other computers, etc.) with an overall objective of discovering des ...

VMware
VMware, Inc. is an American cloud computing and virtualization technology company with headquarters in Palo Alto, California. VMware was the first commercially successful company to virtualize the x86 architecture. VMware's desktop software runs on Microsoft Windows, Linux, and macOS. VMware ESXi, its enterprise software hypervisor, is an operating system that runs on server hardware. In May 2022, Broadcom Inc. announced an agreement to acquire VMware in a cash-and-stock transaction valued at $61 billion. History Early history In 1998, VMware was founded by Diane Greene, Mendel Rosenblum, Scott Devine, Ellen Wang and Edouard Bugnion. Greene and Rosenblum were both graduate students at the University of California, Berkeley. Edouard Bugnion remained the chief architect and CTO of VMware until 2005, and went on to found Nuova Systems (now part of Cisco). For the first year, VMware operated in stealth mode, with roughly 20 employees by the end of 1998. The company was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FreeBSD People
FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed and permissively licensed BSD systems. FreeBSD has similarities with Linux, with two major differences in scope and licensing: FreeBSD maintains a complete system, i.e. the project delivers a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties for system software; FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The FreeBSD project includes a security team overseeing all software shipped in the base distribution. A wide range of additional third-party applications may be installe ...

BSD People
The Berkeley Software Distribution or Berkeley Standard Distribution (BSD) is a discontinued operating system based on Research Unix, developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley. The term "BSD" commonly refers to its open-source descendants, including FreeBSD, OpenBSD, NetBSD, and DragonFly BSD. BSD was initially called Berkeley Unix because it was based on the source code of the original Unix developed at Bell Labs. In the 1980s, BSD was widely adopted by workstation vendors in the form of proprietary Unix variants such as DEC Ultrix and Sun Microsystems SunOS due to its permissive licensing and familiarity to many technology company founders and engineers. Although these proprietary BSD derivatives were largely superseded in the 1990s by UNIX SVR4 and OSF/1, later releases provided the basis for several open-source operating systems including FreeBSD, OpenBSD, NetBSD, DragonFly BSD, Darwin, ...

Toy Story
''Toy Story'' is a 1995 American computer-animated comedy film directed by John Lasseter (in his feature directorial debut), produced by Pixar Animation Studios and released by Walt Disney Pictures. The first installment in the '' Toy Story'' franchise, it was the first entirely computer-animated feature film, as well as the first feature film from Pixar. It was written by Joss Whedon, Andrew Stanton, Joel Cohen, and Alec Sokolow from a story by Lasseter, Stanton, Pete Docter, and Joe Ranft. The film features music by Randy Newman, was produced by Bonnie Arnold and Ralph Guggenheim, and was executive-produced by Steve Jobs and Edwin Catmull. The film features the voices of Tom Hanks, Tim Allen, Don Rickles, Jim Varney, Wallace Shawn, John Ratzenberger, Annie Potts, R. Lee Ermey, John Morris, Laurie Metcalf, and Erik von Detten. 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 a ...

Tin Toy
''Tin Toy'' is a 1988 American computer-animated short film produced by Pixar and directed by John Lasseter. The short film, which runs five minutes, stars Tinny, a tin one-man band toy, attempting to escape from Billy, an infant. The third short film produced by the company's small animation division, it was a risky investment: due to the low revenue produced by Pixar's main product, the Pixar Image Computer, the company was under financial constraints. Lasseter pitched the concept for ''Tin Toy'' by storyboard to Pixar owner Steve Jobs, who agreed to finance the short despite the company's struggles, which he kept alive with annual investment. The film was officially a test of the PhotoRealistic RenderMan software and proved new challenges to the animation team, namely the difficult task of realistically animating Billy. ''Tin Toy'' later gained attention from Disney, who sealed an agreement to create ''Toy Story'' starring Tom Hanks and Tim Allen, which was primarily inspire ...

Luxo Jr
''Luxo Jr.'' is a 1986 American computer-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 Industrial Light & Magic's computer division of Cinetron Computer Systems. 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 an ...

Softimage 3D
Softimage, 3D was a high-end 3D graphics application developed by Softimage, Co., 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 Films, Angel Studios, Walt Dis ...
