The metaverse is a hypothesized iteration of the Internet, supporting persistent online 3D virtual environments through conventional personal computing, as well as virtual and augmented reality headsets. Metaverses, in some limited form, have already been implemented in video games such as Second Life. Some iterations of the metaverse involve integration between virtual and physical spaces and virtual economies. Current metaverse development is centered on addressing the technological limitations with virtual and augmented reality devices. The term "metaverse" has been used as a buzzword for promotion, and as a way to generate hype for public relations purposes by making vague claims for future projects. Information privacy and user addiction are concerns within the metaverse, stemming from current challenges facing the social media and video game industries as a whole. Current implementations •Video games Several components of metaverse technologies have already been develop

  Product-service systems  are business models  that provide for cohesive delivery of products and services. PSS models are emerging as a means to enable collaborative consumption of both products and services, with the aim of pro-environmental outcomes. Product service systems, put simply, are when a firm offers a mix of both products and services, in comparison to the traditional focus on products. As defined by (van Halen, te Riele, Goedkoop) "a marketable set of products and services capable of jointly fulfilling a user's needs", PSSes can be realized by small products. The initial move to PSS was largely motivated by the need on the part of traditional manufacturing firms to cope with changing market forces and the recognition that services in combination with products could provide higher profits than products alone. Faced with shrinking markets and increased commoditization of their products, these firms saw service provision as a new path towards profits and growt

  In  computer programming   and  software development ,   debugging   is the process of finding and resolving bugs   (defects or problems that prevent correct operation) within  computer programs ,  software , or  system . Debugging tactics can involve interactive debugging debugging, control flow analysis, unit  testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps, and profiling. Many programming languages and software development tools also offer programs to aid in debugging, known as  debuggers . The terms "bug" and "debugging" are popularly attributed to Admiral Grace Hopper in the 1940s. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system. However, the term "bug", in the sense of "technical error", dates back at least to

  A   bug tracking system   or   defect tracking system   is a  software application   that keeps track of reported  software bugs   in software development projects. It may be regarded as a type of  issue tracking software. Many bug tracking systems, such as those used by most open source software projects, allow end-users to enter bug reports directly. Other systems are used only internally in a company or organization doing software development. Typically bug tracking systems are integrated with other project management software. A bug tracking system is usually a necessary component of a professional software development infrastructure, and consistent use of a bug or issue tracking system is considered one of the "hallmarks of a good software team". The main benefit of a bug-tracking system is to provide a clear centralized overview of development requests (including both bugs and improvements, the boundary is often fuzzy), and their state. The prioritized list of pendin

Web Development is the work involved in developing a Web site for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing a simple single static page of plain text to complex web applications, electronic businesses, and social network services. A more comprehensive list of tasks to which Web development commonly refers, may include Web engineering, Web design, Web content development, client liaison, client-side/server-side scripting, Web server and network security configuration, and e-commerce development. Among Web professionals, "Web development" usually refers to the main non-design aspects of building Web sites: writing markup and coding. Web development may use content management systems (CMS) to make content changes easier and available with basic technical skills. For larger organizations and businesses, Web development teams can consist of hundreds of people (Web developers) and follow standard methods like Agile

Human enhancement (HE) can be described as the natural, artificial, or technological alteration of the human body in order to enhance physical or mental capabilities. Technologies Existing technologies Three forms of human enhancement currently exist: reproductive, physical, and mental. Reproductive enhancements include embryo selection by preimplantation genetic diagnosis, cytoplasmictransfer, and in vitro-generated gametes. Physical enhancements include cosmetics (plastic surgery & orthodontics), Drug-induced (doping & performance-enhancing drugs), functional (prosthetics & powered exoskeletons), Medical (implants (e.g. pacemaker) & organ replacements ( e.g. bionic lenses)), and strength training (weights (e.g. barbells) & dietary supplement)). Examples of mental enhancements are nootropics, neuro-stimulation, and supplements that improve mental functions. Computers, mobile phones, and Internet can also be used to enhance cognitive efficiency. Notable efforts in

Cloud computing security or, more simply, cloud security refers to a broad set of policies, technologies, applications, and controls utilized to protect virtualized IP, data, applications, services, and the associated infrastructure of cloud computing. It is a sub-domain of computer security, network security, and, more broadly, information security. Security issues associated with the cloud Cloud computing and storage provide users with capabilities to store and process their data in third-party data centers. Organizations use the cloud in a variety of different service models (with acronyms such as SaaS, PaaS, and IaaS) and deployment models (private, public, hybrid, and community). Security concerns associated with cloud computing are typically categorized in two ways: as security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers (companies or organizations who ho
