This chapter examines an efficient algorithm that solves NP problems, the Urbana algorithm. With the Urbana algorithm one can solve all the NP problems quickly, finding the simplest program that classifies data becomes an easy programming exercise. All one needs do is feed in lots of data and the algorithm does the rest. And that lets one learn just about everything. If it turns out that P = NP and the world has efficient algorithms for all NP problems, it will change in ways that will make the Internet seem like a footnote in history. Not only would it be impossible to describe all these changes but the biggest implications of the new technologies would be impossible to predict.

AbstractIn the last 20 years we have moved from a somewhat idealistic vision of the internet to one that is far more nuanced and complex. Disruption and change now surround us in a more uncertain and unpredictable world (Foer, 2017; Greenfield, 2017; Lanier, 2018; O'Neil, 2016). This article examines some of the key changes in the wider world and how they may relate to the use of new technologies in second language learning. This topic is approached from three perspectives that have thus far been relatively unexplored. First, the article looks at digital literacy, a cognate field that has long been motivated by issues and concerns relating to educational technology and the classroom–world connection. Second, it considers the role and use of authentic materials and texts. Third, it contrasts notions of input and output as these terms apply to humans and machines, and as they are used in research on second language learning.The goal throughout is to highlight the benefits of increased connectivity between the wider world and the world of the language classroom. Through increased awareness and informed debate, it is hoped this will place us in a stronger position to understand and plan for the changes ahead.

The Bulletin Board System (BBS), when it first appeared in the middle 1970s, was essentially “a personal computer, not necessarily an expensive one, running inexpensive BBS software, plugged into an ordinary telephone line via a small electronic device called modem” (Rheingold, 1993). The networked computers used to create these parallel worlds and facilitate communication between human beings constitute the technical foundations of computer-mediated communication (CMC) (Nancy, 1998). CMC systems link people around the world into public discussions. While CMC can exist solely between two people or between one person and an anonymous group, increasingly, virtual communities of many people are being formed. With advent of the Internet, the World Wide Web (WWW) brought more new technologies to the BBS. Thousands of BBSs sprang up across the world. Many turned out tremendously successful and evolved into lively virtual communities. These communities provided forums with increasing importance for individuals and groups that share a professional interest or share common activities. Online BBS communities now play an important role in information dissemination and knowledge collaboration on the Internet. On one hand, online forums enable people to disseminate information in an extremely efficient way without geographical restriction. On the other hand, the freedom also comes with uncertainty. Any information can be released and the content is almost beyond control, or even unreliable. To understand the content and quality of the information in BBSs, we would split the task into two subjects: one is to assess the information sources; another is to assess the information providers, people themselves in the virtual communities. Most BBSs are anonymous, because people usually use a pseudonym rather than their real name when registering. A user does not need to provide real personal information to the system, either. Thus, how to assess the trust of the users in a BBS community and attract more trustful and worthy users to participate in the activities of the community have become crucial topics to establish a successful community. Two subjects are important for establishing user trust in a BBS community: First, a BBS system must be able to identify a user and provide efficient security protection for each user and his/her privacy. Second, the value and the trustworthiness of a user should be assessed according to that user’s behavior and contribution to the community in comparison to peers.

Purpose Many investigations are going on in monitoring, contact tracing, predicting and diagnosing the COVID-19 disease and many virologists are urgently seeking to create a vaccine as early as possible. Even though there is no specific treatment for the pandemic disease, the world is now struggling to control the spread by implementing the lockdown worldwide and giving awareness to the people to wear masks and use sanitizers. The new technologies, including the Internet of things (IoT), are gaining global attention towards the increasing technical support in health-care systems, particularly in predicting, detecting, preventing and monitoring of most of the infectious diseases. Similarly, it also helps in fighting against COVID-19 by monitoring, contract tracing and detecting the COVID-19 pandemic by connection with the IoT-based smart solutions. IoT is the interconnected Web of smart devices, sensors, actuators and data, which are collected in the raw form and transmitted through the internet. The purpose of this paper is to propose the concept to detect and monitor the asymptotic patients using IoT-based sensors. Design/methodology/approach In recent days, the surge of the COVID-19 contagion has infected all over the world and it has ruined our day-to-day life. The extraordinary eruption of this pandemic virus placed the World Health Organization (WHO) in a hazardous position. The impact of this contagious virus and scarcity among the people has forced the world to get into complete lockdown, as the number of laboratory-confirmed cases is increasing in millions all over the world as per the records of the government. Findings COVID-19 patients are either symptomatic or asymptotic. Symptomatic patients have symptoms such as fever, cough and difficulty in breathing. But patients are also asymptotic, which is very difficult to detect and monitor by isolating them. Originality/value Asymptotic patients are very hazardous because without knowing that they are infected, they might spread the infection to others, also asymptotic patients might be having very serious lung damage. So, earlier prediction and monitoring of asymptotic patients are mandatory to save their life and prevent them from spreading.

Electronic networking has been welcomed in Australia not least because of its potential to help solve problems of distances within Australia and of the isolation of Australia. In the world as a whole, the Internet, and the World Wide Web in particular, is transforming the communication of art information and access to art images. Three Australian Web servers focus on the visual arts: Art Serve, Diva, and AusArts. A number of initiatives intended to provide online bibliographic databases devoted to Australian art were launched in the 1980s. More recently a number of CD-ROMs have been published. As elsewhere, art librarians in Australia need new skills to integrate these products of new technology into the art library, and to transform the latter into a multimedia resource centre.

<p>The Internet has rapidly become the world’s most prevalent form of communication. It can be accessed twenty-four hours a day from virtually any location in the world from a myriad of technologically savvy devices. Internet users can keep up to date with world events, watch movies, listen to music, interact with government agencies, analyse business trends, undertake research and maintain contact with people anywhere. The Internet also provides the ability for users to shop ‘online’ with virtually any product or service supplier anywhere in the world. This has created concerns regarding the use of personal information obtained through the medium of the Internet. An individual’s right to privacy is a right enshrined in legislation and through tort law. With the uptake of technology and the burgeoning use of the Internet the subject of online privacy has become a complex issue for law and policy makers both in New Zealand and internationally. The aim of this paper is to look at the online shopper or consumer and how their information could be protected. This paper looks at the key areas of privacy legislation, the storage of data and the rise of new technologies including ‘cloud’ computing and suggests that the complexity of online privacy is such that a different approach to access and use of personal information of online shoppers may be required. The rate of technology change, the enormity of the data capture situation and the international accessibility of the Internet are all factors that create an almost impossible situation for ensuring consumer privacy so this paper proposes that the onus moves away from the law and policy makers and put into the hands of the users of the Internet.</p>

The Internet allows us to build a side-world where we invent and re-invent ourselves, relate to the world and face reality through a screen. The new generations are being socialized in virtual surroundings. Which will the consequences be? The step forward from the atom to the bit has determined a new form to see the outside. It has extended the capacity of memory and storage of the human being, but mainly it allows people to relate in a way which will change the idiosyncracy of the man. New technologies are shaping the man. They have already made his body infinite and free, marked by virtual processes that we do not even know. Young people of XXIth century are the digital generation. Internet ha ido construyendo un mundo paralelo donde nos se crea y se recrea, donde nos relacionamos con el mundo y afrontamos la realidad a través de una pantalla. Las nuevas generaciones se están socializando en entornos virtuales, pero ¿cuáles serán las consecuencias? El paso del átomo al bit ha determinado una nueva forma de ver el exterior, ha ampliado la capacidad de memoria y almacenamiento del ser humano, pero sobre todo permite una forma de relacionarse que cambiará la idiosincrasia del hombre. Las nuevas tecnologías modelan al hombre, lo han hecho infinito, libre de su cuerpo, condicionado por procesos virtuales que aun no se conocen. Los jóvenes del siglo XXI son la generación digital.

With the explosion of public awareness of the Internet in the early 1990s, much attention has been focused on ways in which these new technologies can be used in developing nations. Some of the primary proponents of these initiatives include the World Bank, The United Nations Conference on Trade and Development (UNCTAD) and the Inter American Development Bank. The major themes include ways in which the Internet and electronic commerce can be harnessed for development, impediments to rapid diffusion of Internet technologies and success stories in small and medium companies.

The 1990s have been marked by extraordinary changes in many of the fundamental elements of human existence, among the most powerful, the introduction of a global networking system. Indeed, it is difficult to consider thoughtfully any major aspect of our socio-economic-political circumstances, current and future, that are not in some way profoundly affected by this revolution. For those of us with Internet service, even a few keystrokes on a laptop computer can now put us in touch with friends, family, colleagues, or strangers almost anywhere in the world, certainly on all seven continents including Antarctica. Business can be conducted, money transferred, medical records evaluated, books/papers jointly written and edited, inventions created, ideas shared. The unprecedented ease and speed of access to knowledge and experience, and increasingly commerce, is at the heart of the promise of the new technologies for cyberconnectivity. Communities in all parts of the world are finding ways to make the Internet serve them, and becoming energized, organized and activated as a result. Two factors, however, contribute to a sobering backdrop that frames further exploration of these exciting new frontiers. First, access to the underlying technologies is severely constrained in developing countries, and in poorer communities of industrialized countries. Differential access to key resources, such as capital, electricity, telephone service, exacerbates gaps between the haves and the have-nots. Furthermore, even for those who gain basic access, other constraints, such as predominance of “colonial” languages, limit their ability to take advantage of opportunities offered by the technology. Second, the glitter of cybertechnology tends to divert us from addressing broader problems of inequities in social and economic development, and their associated ecological consequences. These have been sharply documented in the UNDP Human Development Report Series. (The most recent of these 10 annual Human Development Reports, that of July 1999, can be found at: http://www.undp.org/hdro/99.htm.) This chapter presents the results of an experiment to bring together these two contemporary forces — the Internet explosion, and a sense of growing inequality in economic and political power — to create a new channel into global decision making fora, particularly for communities that seem increasingly to be left behind. The context for this effort was the United Nations, and a series of global conferences that focused attention on the major social, environmental, and economic issues of our time. The objective was to explore ways to use new electronic networking to link communities around the world more directly to top level decision makers.

Cultural globalization arises from increased cultural flows across the world. ‘The cultural dimension of globalization’ focuses on the tension between cultural sameness and cultural difference, broadly defining culture as the ideas, customs, and social behaviour of people or society. The globalization of culture is often primarily attributed to international mass media. New technologies such as satellite television and the Internet have created a steady flow of images and messages which have had a strong effect on cultures and communities, profoundly impacting the way people experience their everyday lives. As the world becomes more connected, language diversity is decreasing as more languages become obsolete.

How have relatively new technologies changed the way in which the celebrity system and tabloid culture function in North American culture? With access to technologies, such as the internet and digital film and photography, and websites, such as Youtube.com, the average citizen is now able to actively participate in the world of celebrity and even turn themself into a celebrity figure. The world of celebrity (online, at least) has become do-it-yourself and has, in many ways, democratized the process of fame. Through the rise in online readership and recognition, even the creators of online tabloids have themselves become celebrities and active members in the star system they seek to critique. This thesis will demonstrate that the technologies used to demystify the celebrity through perpetual surveillance have, at the same time, succeeded in turning ordinary people into celebrities, thus placing them squarely within the star system they never intended to inhabit.
