Second Life is an online multimedia platform that allows people to create an avatar for themselves and have a second life in an online virtual world. Developed and owned by the San Francisco-based firm Linden Lab and launched on June 23, 2003, it saw rapid growth for some years and in 2013 it had approximately one million regular users. Growth eventually stabilized, and by the end of 2017 the active user count had declined to "between 800,000 and 900,000". In many ways, Second Life is similar to massively multiplayer online role-playing games; nevertheless, Linden Lab is emphatic that their creation is not a game: "There is no manufactured conflict, no set objective".
A virtual world is a computer-simulated environment which may be populated by many users who can create a personal avatar, and simultaneously and independently explore the virtual world, participate in its activities and communicate with others. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Virtual worlds are closely related to mirror worlds.
Furcadia is a free-to-play MMOSG/MMORPG or graphical MUD, set in a fantasy world inhabited by magical creatures. The game is based on user-created content with emphasis on world building tools, exploring, socializing, and free-form roleplaying. Furcadia hosts a large volunteer program called the Beekin Helpers, allowing players to help with community moderation, welcoming new players, handling in-game technical support, running in game events, creating art for the game itself, accessing and updating the game's website, and bug hunting. Furcadia holds the Guinness World Records title for the longest continuously running social MMORPG and in addition to being one of the first games to heavily encourage modding and let users build virtual worlds for themselves, it was also one of the first freemium online games. In 2008, Furcadia was reported as having over 60,000 players.
In futurism and science fiction, the metaverse is a hypothetical iteration of the Internet as a single, universal and immersive virtual world that is facilitated by the use of virtual reality (VR) and augmented reality (AR) headsets. In colloquial use, a metaverse is a network of 3D virtual worlds focused on social connection.
A virtual power plant (VPP) is a cloud-based distributed power plant that aggregates the capacities of heterogeneous distributed energy resources (DER) for the purposes of enhancing power generation, as well as trading or selling power on the electricity market. Examples of virtual power plants exist in the United States, Europe, and Australia.
Teen Second Life was a version of Second Life reserved for teenagers, running on the so-called "Teen Grid." It was officially opened to the public on February 14, 2005 for people aged 13–17 to use Second Life, without entering false information to participate in Second Life . On January 1, 2006, Teen Second Life's operating hours were increased to 24 hours a day, whereas it was previously open only from noon to 10 pm Pacific Time.
4D film is a high technology presentation system combining motion pictures with physical effects that are synchronized and occur in theatre. Effects simulated in 4D films include motion, vibration, scent, rain, mist, bubbles, fog, smoke, wind, temperature changes, and strobe lights. Advanced seats in 4D venues vibrate and move during these multisensory presentations. Other common effects include air jets, and water sprays. Auditorium effects may include smoke, rain, lightning, bubbles, and scent. 4D films are exhibited in every major global market in stadium seating multiplexes and are exhibited via worldwide theatrical releases.
In the virtual world of Second Life, there are a number of in-world business and user-groups founded specifically for the game, some of which have become legal entities in their own right, as well as preexisting companies and organizations that have involved themselves in the world.
Kernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules.
OpenSimulator is an open-source server platform originally launched in 2007 for hosting virtual worlds and metaverse environments. It is largely compatible with the virtual world Second Life but full compatibility is not a design goal.
The Virtual Universe Community or VUC is the internal IBM interest group for Virtual Worlds.
The Second Life Grid is the platform and technology behind 3D online virtual world Second Life. In April 2008, IBM announced that it would explore future deployment of a portion of the Second Life Grid behind a corporate firewall.
Virtual worlds are playing an increasingly important role in education, especially in language learning. By March 2007 it was estimated that over 200 universities or academic institutions were involved in Second Life. Joe Miller, Linden Lab Vice President of Platform and Technology Development, claimed in 2009 that "Language learning is the most common education-based activity in Second Life". Many mainstream language institutes and private language schools are now using 3D virtual environments to support language learning.
AutoDock is a molecular modeling simulation software. It is especially effective for protein-ligand docking. AutoDock 4 is available under the GNU General Public License. AutoDock is one of the most cited docking software applications in the research community. It is used by the FightAIDS@Home and OpenPandemics - COVID-19 projects run at World Community Grid, to search for antivirals against HIV/AIDS and COVID-19. In February 2007, a search of the ISI Citation Index showed more than 1,100 publications had been cited using the primary AutoDock method papers. As of 2009, this number surpassed 1,200.
Second Life is used as a platform for education by many institutions, such as colleges, universities, libraries and government entities.
4DX is a 4D film format developed by CJ 4DPlex, a subsidiary of South Korean cinema chain CJ CGV. It allows films to be augmented with various practical effects, including motion seats, wind, strobe lights, simulated snow, and scents.
