Dev Null
Dev Null was an animated virtual reality character created in 1996 by Leo Laporte for MSNBC's computer and technology TV series ''The Site''. Espresso barista Dev talked with host Soledad O'Brien each weeknight in a five-minute segment. Laporte was awarded a 1997 Northern California Emmy for his nightly performances as cyber character Dev Null. Background and history Dev was animated in real time on a million-dollar Silicon Graphics Onyx computer. Laporte generated both the voice and actions while wearing a VR motion capture suit. When O'Brien sat at the espresso bar to read email from viewers, Dev flirted with her while answering her computer questions. She recalled, "One of the reasons that segment of the show worked is that I could not see him as I was talking to him, and the segment was unscripted. He was funny, and his jokes were not gags." While O'Brien looked at a piece of tape on the wall indicating Dev's virtual position, the VR suit captured Laporte's actions, and a com ...

Devnull
Devnull is the name of a computer worm for the Linux operating system that has been named after , Unix's null device. This worm was found on 30 September 2002. This worm, once the host has been compromised, downloads and executes a shell script from a web server. This script downloads a gzipped executable file named from the same address, and then decompresses and runs the file. This downloaded file appears to be an IRC client. It connects to different channels and waits for commands to process on the infected host. Then the worm checks for presence of the GCC compiler on the local system and, if found, creates a directory called . Next, it downloads a compressed file called . After decompressing, two files are created: an ELF binary file called and a source script file called . The latter gets compiled into the ELF binary . The executable will scan for vulnerable hosts and use the compiled program to exploit a known OpenSSL vulnerability. See also *Linux malware Linux m ...

Virtual Reality
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silicon Graphics
Silicon Graphics, Inc. (stylized as SiliconGraphics before 1999, later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS) was an American high-performance computing manufacturer, producing computer hardware and software. Founded in Mountain View, California in November 1981 by Jim Clark, its initial market was 3D graphics computer workstations, but its products, strategies and market positions developed significantly over time. Early systems were based on the Geometry Engine that Clark and Marc Hannah had developed at Stanford University, and were derived from Clark's broader background in computer graphics. The Geometry Engine was the first very-large-scale integration (VLSI) implementation of a geometry pipeline, specialized hardware that accelerated the "inner-loop" geometric computations needed to display three-dimensional images. For much of its history, the company focused on 3D imaging and was a major supplier of both hardware and software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion-capture Acting
Motion-capture acting, also called performance-capture acting and often abbreviated as mo-cap or P-cap, is a type of acting in which an actor wears markers or sensors on a skintight bodysuit or directly on the skin. Hugh Hart, January 24, 2012, Wired magazineWhen will a motion capture actor win an Oscar? Accessed June 21, 2014, "...the Academy of Motion Picture Arts and Sciences’ historic reluctance to honor motion-capture performances ....." January 25, 2012, Calgary HeraldNo Oscar nod for Andy Serkis: master of motion-capture acting Accessed June 21, 2014, "..Serkis has carved out a niche for himself as master of motion-capture roles..." Several cameras from different angles record the actor's movements simultaneously, recording the three-dimensional position of the sensors without recording the rest of the actor. Sampling is done many times each second, aided by advances in computer technology. The resulting database of 3D points permits a filmmaker or video game creator to cr ...

Vision Mixer
A vision mixer is a device used to select between several different live video sources and, in some cases, compositing live video sources together to create visual effects. In most of the world, both the equipment and its operator are called a vision mixer or video mixer; however, in the United States, the equipment is called a video switcher, production switcher or video production switcher, and its operator is known as a technical director (TD). The role of the vision mixer for video is similar to what a mixing console does for audio. Typically a vision mixer would be found in a video production environment such as a production control room of a television studio, production truck or post-production facility. Capabilities and usage Besides hard cuts (switching directly between two input signals), mixers can also generate a variety of transitions, from simple dissolves to pattern wipes. Additionally, most vision mixers can perform keying operations (called mattes in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

/dev/null
In some operating systems, the null device is a device file that discards all data written to it but reports that the write operation succeeded. This device is called /dev/null on Unix and Unix-like systems, NUL: (see TOPS-20) or NUL on CP/M and DOS (internally \DEV\NUL), nul on OS/2 and newer Windows systems (internally \Device\Null on Windows NT), NIL: on Amiga operating systems, and NL: on OpenVMS. In Windows Powershell, the equivalent is $null. It provides no data to any process that reads from it, yielding EOF immediately. In IBM operating systems DOS/360 and successors and also in OS/360 and successors such files would be assigned in JCL to DD DUMMY. In programmer jargon, especially Unix jargon, it may also be called the bit bucket or black hole. History According to the Berkeley UNIX man page, Version 4 Unix, which AT&T released in 1973, included a null device. Usage The null device is typically used for disposing of unwanted output streams of a process, or as a conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
