Hvordan forholder man sig til det moderne menneskes afhængighed over for computeren og andre medier?For at få ro til at finde svaret, opsøger forfatteren kirkegården. Her taler han problemerne igennem med et gammelt egetræ, som begejstret lever sig ind i beretningen om hans dag med alle dens impulser, tilbud og krav.Samtaler med et træ er et forsøg på at vise forskellen på verdens viden og træets visdom, på information og klogskab, og et opgør med myten om at information er god og nyttig til alle tider i alle sammenhæng. Bogen er en odyssé gennem alle de problemer, som det moderne samfunds opmærksomhedskrige starter, og ved forfatterens beretning forundres træet over computernes og informationshungerens magt over menneskers fantasi, deres vaner, deres liv.Bogen er fuld af humor, alvor, satire, ironi og ærlighed. Den er således en vigtig modgift mod den ureflekterede betagelse af teknologiens muligheder. Bogen er udgivet internationalt og har solgt mere end 12000 eksemplarer i Danmark. I Danmark har den modtaget en pris fra forfatterforeningen for at være årets mest interessante bud på en anderledes fagbog.Et uddrag af bogen kan læses på: www.stemningshotellet.dk

In July 1976 a new type of Integrated Circuit was released into the world and over half a century later it is still in production. This device is the Zilog Z80 processor and its longevity surely makes it one of the most successful electronic devices ever produced.This device spawned the rapid development of multitude of relatively low cost personal computer systems which would previously have been impossible to produce.This book is aimed at anyone who has ever wanted to design their own Z80 based computer system. From first principles to a fully working computer it delves into circuit design at the discrete logic level. Each circuit is fully described in detail and although this computer has many of the features found in many vintage computer systems it avoids the use of large scale integration devices. Each circuit is constructed using discrete logic gates to provide a fully immersive development experience.

The Financial Times - Best books of 2022: Politics 'The prolific military chronicler and analyst Mark Galeotti has produced exactly the right book at the right time.' The Times A new history of how Putin and his conflicts have inexorably reshaped Russia, including his devastating invasion of Ukraine. Putin's Wars is a timely overview of the conflicts in which Russia has been involved since Vladimir Putin became prime minister and then president of Russia, from the First Chechen War to the two military incursions into Georgia, the annexation of Crimea and the eventual invasion of Ukraine itself. But it also looks more broadly at Putin's recreation of Russian military power and its expansion to include a range of new capabilities, from mercenaries to operatives in a relentless information war against Western powers. This is an engrossing strategic overview of the Russian military and the successes and failures on the battlefield. Thanks to Dr Galeotti's wide-ranging contacts throughout Russia, it is also peppered with anecdotes of military life, personal snapshots of conflicts, and an extraordinary collection of first-hand accounts from serving and retired Russian officers. Russia continues to dominate the news cycle throughout the Western world. There is no better time to understand how and why Putin has involved his armed forces in a variety of conflicts for over two decades.

Despite repeated warnings from the White House, Russia's invasion of Ukraine in February 2022 shocked the world. Why did Putin start the war-and why has it unfolded in previously unimaginable ways? Ukrainians have resisted a superior military; the West has united, while Russia grows increasingly isolated.Serhii Plokhy, a leading historian of Ukraine and the Cold War, offers a definitive account of this conflict, its origins, course, and the already apparent and possible future consequences. Though the current war began eight years before the all-out assault-on February 27, 2014, when Russian armed forces seized the building of the Crimean parliament-the roots of this conflict can be traced back even earlier, to post-Soviet tensions and imperial collapse in the nineteenth and twentieth centuries. Providing a broad historical context and an examination of Ukraine and Russia's ideas and cultures, as well as domestic and international politics, Plokhy reveals that while this new Cold War was not inevitable, it was predictable.Ukraine, Plokhy argues, has remained central to Russia's idea of itself even as Ukrainians have followed a radically different path. In a new international environment defined by the proliferation of nuclear weapons, the disintegration of the post-Cold War international order, and a resurgence of populist nationalism, Ukraine is now more than ever the most volatile fault line between authoritarianism and democratic Europe.

"As a pioneer of ubiquitous computing-the embedding of technology in everyday objects from thermostats to doorbells-computer scientist Mark Weiser's descriptions of smart homes, now thirty years later, might seem to approach our reality. Weiser's views certainly influenced our technology's developers-his 1991 Scientific American article 'The Computer for the 21st Century' was flagged a must-read by Microsoft's Bill Gates and then circulated among the day's digirati, including those Silicon Valley insiders who crowded his beer garden-based 'office hours.' Unlike many of his contemporaries, Weiser's vision was motivated by the philosophies of Michael Polanyi and Martin Heidegger, collaboration with anthropologists such as Lucy Suchman, and insights from artists including Natalie Jeremijenko. He hoped to realize 'tacit computing' as an escape from a single attention-grabbing screen as a portal to work, entertainment, and education. When rivals such as Nicholas Negroponte at MIT's Media Lab championed the development of smart agents (the ancestors of Siri and Alexa) or pervasive sensing in wearable technologies (proto-Fitbits or Apple Watches), Weiser balked. Weiser wanted computers to be something closer to the white cane a person with low vision might use to navigate the world. Good technology, he argued, should not mine our experiences for data to sell or demand our attention. Technology should not rob its users of the hardships that establish their expertise, but instead give them the ability to conceive of the world in new ways. In this compelling biography of a person and idea, digital studies scholar John Tinnell shows Weiser, who died of cancer at 46, would be heartbroken if he had lived to see the ways we use technology today. Informed by deep archival research and interviews with Weiser's family and Xerox PARC colleagues, this book uses Weiser's life to offer a new history of today's technological reality, an inside view of Xerox PARC during its heyday, and a compelling vision of what computers failed to be"--

'History is made up of myths,' writes the renowned Russian dissident journalist Mikhail Zygar. 'Alas, our myths led us to the fascism of 2022. It is time to expose them.' Drawing from his perilous career investigating the frontiers of the Russian empire, Zygar reveals how 350 years of propaganda, bad historical scholarship, folk tales and fantasy spurred his nation into war with Ukraine.A noted expert on the Kremlin with unparalleled access to hundreds of players in the current conflict - from politicians to oligarchs, gangsters to comedians (not least Zelensky himself) - Zygar chronicles the power struggles from which today's politics grew, and digs out the essential truths from behind layers of seductive legend. By surveying the strange, complex record of Russo-Ukrainian relations, WAR AND PUNISHMENT reveals exactly how the largest nation on Earth lost its senses. A work of history can't undo the past or transform the present, but sometimes it can shape the future.

Oleksandr Zinchenko's story is so much more than a typical footballer's story. He has shown heroism of a very different kind through his extraordinary campaigning in support of Ukraine throughout the ongoing war with Russia. Although his instinct was to join the fight, he decided - following the advice from close loved ones - that he could make the most difference by using his platform to spread awareness and raise money. A fan favourite at Arsenal and previously at Manchester City, Zinchenko, has been lighting up the Premier League with his fearless performances for many years. Although, his success has not come without its challenges. Having begun his career as a teenager at Shakhtar Donetsk, his world was upended when Russia invaded the Donbas region and he was stranded in Russia. But after he joined Manchester City in 2016 he would go on to experience exhilarating career highs, with four league titles in six years, before moving to Arsenal where he has played an integral part in their return to the top.Written with candour and bravery, Triumph & Tears is no ordinary tale of success on the pitch, but one of unwavering strength and integrity, tempered by sadness and anger. It provides unique insights into the methods of Pep Guardiola and Mikel Arteta. It is the story of a selfless man who prioritised his homeland's welfare before his own - delivering his best on and off the field.

Internet of Things (IoT) is coined in 1999 by Kevin Ashton. IoT can be de¿ned in many ways. 'Internet' refers to the interconnectivity of devices to create a network, and 'Things' refers to the embedded objects or devices that can connect to the Internet. One way of de¿ning is, 'it is a network of sensors and smart devices which sense the data which is further processed and analysed in an ubiquitous network.' IoT has seen rapid development in recent years because of its 'smartness.' The various applications of IoT include Smart City, Smart Home, Smart Health, Transport and Logistic applications, Weather monitoring and Forecast etc. These applications have millions of devices generating large volumes of data. The rapid development of IoT has increased the curiosity of the attackers. The devices (nodes) in the IoT network have weak security protocols because of their limited computation ability and energy. Hence the nodes of the network are vulnerable to various kinds of attacks. The IoT network has sensors, actuators, controllers, gateway heads, sink, etc. For our reference, we have broadly classi¿ed these devices into sensor nodes and gateway nodes. Sensor nodes includes low computation end devices such as sensors, actuators etc., and gateway node includes gateway, sink, cluster head etc. The gateway nodes have better computation power as compared to sensor nodes. But the overall network is not competent to handle complex cryptographic operations. Signature is a unique way to identify a signer. The authenticity of a person/ organization/ entity is veri¿ed through its signature. A signature can be a handwritten one, or it can be a digital one. Digital signatures are used to verify the content of the received message and the signer's identity in digital communication. The exponential growth of Internet technology has led to the growth in usage of digital signatures. Every signer generates a unique signature using his/her private key. The veri¿er possesses the public key of the signer and veri¿es the signature using the same. The signature generated by the signer can be veri¿ed by everyone who has access to the public key. The concept of batch veri¿cation is introduced to reduce the veri¿cation time and complexity. Batch veri¿cation schemes verify multiple signatures together with signatures either signed by single or multiple signers.
