The concept of the so-called ubiquitous computing was introduced in the early 1990s as the third wave of computing to follow the eras of the mainframe and the personal computer. Unlike previous technology generations, ubiquitous computing recedes into the background of everyday life: It activates the world, makes computers so imbedded, so fitting, so natural, that we use it without even thinking about it, and is invisible, everywhere computing that does not live on a personal device of any sort, but is in the woodwork everywhere. (Weiser & Brown, 1997, p. 81)

The concept of the so-called Pervasive and Ubiquitous Computing was introduced in the early nineties as the third wave of computing to follow the eras of the mainframe and the personal computer. Unlike previous technology generations, Pervasive and Ubiquitous Computing recedes into the background of everyday life: “it activates the world, makes computers so imbedded, so fitting, so natural, that we use it without even thinking about it, and is invisible, everywhere computing that does not live on a personal device of any sort, but is in the woodwork everywhere” (Weiser 1991). Pervasive and Ubiquitous Computing is often referred to using different terms in different contexts. Pervasive, 4G mobile and sentient computing or ambient intelligence also refer to the same computing paradigm. Several technical developments come together to create this novel type of computing, the main ones are summarized in Table 1 (Davies and Gellersen 2002; Satyanarayanan 2001).

The concept of ubiquitous computing or Ubicomp was first articulated by Mark Weiser in 1988 at the Computer Science Lab at Xerox PARC (Palo Alto Research Centre). He asserted that the most profound technologies associated with ubiquitous computing are those that disappear as they weave themselves into the framework of our everyday lives. He described Ubicomp as the third wave of computing. The first wave of computing, from 1940 to about 1980, saw the use of one mainframe computer by many people. The second wave saw a one-to-one computer to human ratio where individuals were connected to desktops or laptops. We are now in the third wave of computing where many computers dispersed throughout the physical environment, service one person, and as these technologies recede into the background of people’s lives, they are increasingly being used unconsciously for task completion (Weiser, 1991, 1996). In this regard, ubiquitous computing is viewed as the age of “calm technology” (Weiser and Brown, 1996). In a similar analogy, O’Malley & Fraser (2006) describe technology associated with ubiquitous computing as “tangible” in which “the technology is so embedded in the world that it ‘disappears’ ” (p.2).

  The COVID -19 pandemic has hit the world for a period of a year and a half; it has been a triple crisis, with medical, economic, and psychological consequences. After 18 months of going through a pandemic, this includes not only facing the transmission of SARS CoV-2 virus but also restricted movements. Communities are now facing pandemic fatigue starting as early as the third wave of increased cases in September 2020. Pandemic fatigue is the stage when the initial enthusiasm and eagerness to tackle the crisis is replaced by feelings of exhaustion. In a simple definition, pandemic fatigue is understood as demotivation to follow recommended protective behaviours. It is a natural and expected reaction to sustained and unresolved adversity in people’s lives, evolving gradually over time and affected by several emotions, experiences, and perceptions as well as the cultural, social, structural, and legislative environment.

ResumoA partir de uma crônica de Bráulio Tavares, este artigo reflete sobre cenas da precariedade de ontem e de hoje. A primeira cena está em Lima Barreto, em Recordações do escrivão Isaías Caminha, ao referir a Revolta da Vacina no Rio de Janeiro do século XX, comparada às manifestações de 2013 e 2014 no país; a segunda é a espetacularização da mídia sobre as manifestações de rua em 2013 e 2014, e sobre o processo de impedimento do mandato presidencial de Dilma Rousseff em 2015; a terceira é uma cena da vida cotidiana de uma moça de Brasília em outubro de 2014. As três situações revelam o mundo da classe trabalhadora e seu desamparo em meio ao espetáculo midiático.Palavras-chave: Trabalho. Mídia. Política. Espetáculo. AbstractFrom a chronicle by Bráulio Tavares, this paper reflects about scenes of the precariousness of yesterday and today. The first scene is in Lima Barreto’s novel Recordações do escrivão Isaías Caminha (Memories of the scrivener Isaías Caminha), when referring to the Vaccine Revolt in the Rio de Janeiro of the 20th century, compared to the manifestations of 2013 and 2014 in Brazil; the second is about the media spectacularization of the street manifestations between 2013 e 2014 in Brazil, and also on Dilma Rousseff's impeachment process in 2015; the third one is from the everyday life of a girl from Brasília in October of 2014. All those three situations reveal the world of the working class and its helplessness in the face of the media spectacularization.Keywords: Work. Media. Politics. Spectacle.

Feminism has been a good movement with the noble aim of freeing the world from the shackles of an evil superiority of men over women. The principal of feminism as a movement was political equality between men and women. In itself, it was a fair and just course such that it was inclusive of men as well, men were also part of the movement with no insults, threats, and hate speech. But in this technological era some impurities have also crept into it. From the third wave of feminism which is also known as GRRRL feminism which turned the offensive names into jokes and somehow normal to be pronounced in public, things became no longer about equality and respect of humanity. As feminism grew, it became less critical and became more sensitive towards emotions and uncritical amassment of followers. To some extent, being critical about feminism is unacceptable because someone becomes quickly accused of being patriarchal and antifeminism. Indeed, patriarchy is a negative and destructive idea perpetrated by those who were suffering from testosteron-epowersyndrome . But, when some thinkers like Valenti, Arndt, and Harrow have identified the syndrome and implemented some medication to it, others inject the other side with similarly fatal ideas. I call those ideas Oestrgoen-powersyndrome because they make their victims think that with collapse of patriarchy, men should be disgraced and be made to feel not existentially necessary. Symptoms of this syndrome start from no more knowing that hating the other sex is wrong and should not be promoted. Writers like Annapuranny and Jansen even perpetrate non progressive talks like “what’s wrong with hating men”, “the world would be better off without men” and many phrases of such destructive nature. But the issue which this paper seeks to address is that there is no philosopher who has critically tackled this matter. In fact, some African philosophers rather reject the whole feminism movement as non-African. Using analytical framework, this research ventures into critical analysis of this issue of feminist extremism coupled with the silence of African philosophers.

A dramatic change by the growth of new ubiquitous computing, our globe is moving towards the fully connected paradigm called Internet of Things (IoT). The world is being connected and interlinked with the exponential growth of this pervasive technology. It plays a significant role in many fields such as healthcare, manufacturing industry, agriculture, transportation, smart homes etc and reinforces our everyday life. It acts as an aegis for covering all the factors such as protocols, key elements, technologies etc. IoT includes many capabilities and numerous mechanisms but protection hassle that slow down the era. In this paper we discussed about essential protocols and security issues of IoT.

No global political trend in the last quarter of the 20th century has been more far-reaching and profound than the growth of democracy. During what Samuel P. Huntington has called the “third wave” of democratization, the percentage of states in the world that are democratic has grown from 27 (when the third wave began in 1974) to 61 percent. The trend was particularly powerful during the first half of the 1990s, when the number of democracies increased from 76 to 117, where it has essentially remained during the subsequent four years.

Recent years have seen the swift development and deployment of Internet-of-Things (IoT) applications in a variety of application domains. In this scenario, people worldwide are now ready to delight the benefits of the Internet of Things (IoT). The IoT is emerging as the third wave in the evolution of the Internet. The 1990s’ Internet wave connected 1.2 billion subscribers while the 2000s’ mobile wave connected another 2.4 billion. Actually, IoT is expected to consist of more than 84 billion connected devices generating 186 zettabyte of data by 2025, in the opinion of IDC. It includes major types of networks, such as distributed, ubiquitous, grid, and vehicular, these have conquered the world of information technology over a decade. IoT is growing fast across several industry verticals along with increases in the number of interconnected devices and diversify of IoT applications. In spite of the fact that, IoT technologies are not reaching maturity yet and there are many challenges to overcome. The Internet of Things combines actual and virtual anywhere and anytime, fascinate the attention of both constructor and hacker. Necessarily, leaving the devices without human interference for a long period could lead to theft and IoT incorporates many such things. In this paper, we are briefly discussing technological perspective of Internet of Things security. Because, the protection was a major concern when just two devices were coupled. In this context, security is the most significant of them. Today scenario, there are millions of connected devices and billions of sensors and their numbers are growing. All of them are expected secure and reliable connectivity. Consequently, companies and organizations adopting IoT technologies require well-designed security IoT architectures.

For twenty years, humanity has seen the third attempt at the transition of coronavirus to humans. The vaccine has been found, but coronavirus transitions will not stop even with the improvement of medicine. Nobel laureate in medicine Professor Luc Montagnier argues that vaccines may not live up to humanity's hopes of getting rid of COVID-19. Collective immunity for coronavirus has not been developed, repeated infections are more and more common, beds of seriously ill people are not empty, and mortality is running high, no one knows what will happen to all of us. In Israel, where vaccination has long been compulsory, and over 60% of the population, including underage children, have been vaccinated, the incidence is not just declining, but still breaking all records. So, the maximum number of cases here was revealed on September 1 - 16,629, which almost caught up with Russia (18,368 confirmed on the same September 1) with our percentage of vaccinated 26.1% of the number of citizens. At the end of September 2021, morbidity and mortality increase, because it is a system. Based on existing monthly pneumonia mortality statistics over the past 15 years, there are three waves each year. Since September 22, there has been a surge of pneumonia, ARI, and even non-communicable diseases. The second wave comes at the end of December - January, it is usually three times larger than the first. Then around March-April there is a third wave. These three waves exist steadily from year to year, their amplitudes can change, then one will be higher, then the other, they are not absolutely hard on schedule, but they are reproduced regularly in other countries. The first wave of the Spanish pandemic covered the world just at the end of September 1918. The coronavirus was the same. The first wave in America is September 2019, an unexplained surge of pneumonia with a rather high mortality rate, which was written off for smoking e-cigarettes and called "vape." Now they decided to watch the surviving tests of patients, and there - COVID-19. In Europe, it was the same.
