A decade ago, developers built information-sharing software by writing a lot of custom code in a single code base, then adding layers of caching. Now we build information systems: interdependent software and services, data platforms, and event streams. Many of our software-to-systems initiatives fail, though, and when they do, we double down on traditional linear approaches. But linear thinking cannot resolve systems challenges. We need to shift to systems thinking.

How does a neural network become a brain? While neurobiologists investigate how nature accomplishes this feat, computer scientists interested in AI strive to achieve this through technology. The Self-Assembling Brain tells the stories of both fields, exploring the historical and modern approaches taken by the scientists pursuing answers to the quandary: What information is necessary to make an intelligent neural network? As Peter Robin Hiesinger argues, "the information problem" underlies both fields.

Rick Howard, the Chief Security Officer, Chief Analyst, and Senior fellow at The Cyberwire, challenges the conventional wisdom of current cybersecurity best practices, strategy, and tactics and makes the case that the profession needs to get back to first principles.

The Wireless World sets out a new research agenda for the history of international broadcasting, and for radio history more generally. It examines global and transnational histories of long-distance wireless broadcasting, combining perspectives from international history, media and cultural history, the history of technology, and sound studies. Bringing together their knowledge of a wide range of different countries, languages, and archives, the coauthors show how broadcasters and states deployed international broadcasting as a tool of international communication and persuasion.

Cybersecurity All-in-One For Dummies covers a lot of ground in the world of keeping computer systems safe from those who want to break in. This book offers a one-stop resource on cybersecurity basics, personal security, business security, cloud security, security testing, and security awareness. Filled with content to help with both personal and business cybersecurity needs, this book shows you how to lock down your computers, devices, and systems—and explains why doing so is more important now than ever.

Optimization is the driving principle of our modern world. We now can manufacture, transport, and organize things more cheaply and faster than ever. Optimized models underlie everything from airline schedules to dating site matches. We strive for efficiency in our daily lives, obsessed with productivity and optimal performance. How did a mathematical concept take on such outsize cultural shape? And what is lost when efficiency is gained? Optimal Illusions traces the fascinating history of optimization from its roots in America’s founding principles to its modern manifestations.

Hacker culture can be esoteric, but this entertaining reference is here to help. Written by a longtime hacker, this fun reference introduces you to key people and companies, fundamental ideas, and milestone films, games, and magazines in the annals of hacking. From phreaking to deepfakes, and from APT (advanced package tool) to zombie malware, grasping the terminology is crucial to understanding hacker culture and history.

Most companies developing software employ something they call "Agile." But there's widespread misunderstanding of what Agile is and how to use it. If you want to improve your software development team's agility, this comprehensive guidebook's clear, concrete, and detailed guidance explains what to do and why, and when to make trade-offs.

■空気のようなインターネット 2016年に『さよならインターネット　まもなく消えるその「輪郭」について』という本を中央公論新社から出しました。インターネット論というほどのものではないけれど、これまでのインターネットと、これからのインターネットについて真面目に語ったもので、最近だとドワンゴの川上量生（かわかみ・のぶお）さんが出した『鈴木さんにも分かるネットの未来』（岩波書店）と、方向性は似ています。 発端は、僕が知り合いの編集者に、うちの会社にいる二十歳のインターンの子の話を、なにげなくしたことでした。 そのインターンの子は、こんなことを言っていました。 「家入さんはよくインターネットが大好きって言ってますけど、僕にはよくわか らないんです。なんだか、例えばハサミを好きって言ってるみたいで……」(本文より) 家入一真　「家入学級」はこちらから→ http://yakan-hiko.com/ieiri.html

ダイソンが掃除機や扇風機で蓄積してきたノウハウを活かして参入した“ヘアドライヤー”という新しい事業領域。その高価格（4万5000円）が話題だ。高価だけに、SNSのタイムラインで検索をすると、本当にその価値があるのか？という視点での話題が拡がっている。 また、高価格を肯定するために、必要以上に広告やPRで消費者をミスリードするメッセージを出しすぎているのではないか？　という意見もあった。家電ベンチャーCEREVOを経営する友人の岩佐氏は「618gのドライヤなんて軽くないぞ！　メディアよ、ダイソンのPR戦略に踊らされるな！ ...という話」というブログを書いていた。 ダイソンの製品は悪くないが、そのPR戦略の踊らされているマスコミはおバカであるという指摘だ。実際にお馬鹿な記事が大量にあるかどうかはともかく、ダイソンが“消費者を踊らせるPR戦略”をしているかというと、まったくそんなことはない。(本文より) 本田雅一　続・モバイル通信リターンズはこちらから→http://yakan-hiko.com/honda.html

2016年3月に筆者はアメリカ・サンフランシスコに出張した。出かける前後、日本で話題になっていたのが、Googleが開発した囲碁用AI「AlphaGo」と、囲碁の世界チャンピオン・李世ドルの対決だ。アメリカでは日本ほど話題になっていないようだが、そこは囲碁というゲームに対する認知度というか、注目度の差かな、と思う。筆者は囲碁にはさほど詳しくない。弱いながら、将棋とチェスはそこそこわかるが、囲碁はルールを知っている程度。場の展開の有利・不利がどうにも見通せない、というレベルに過ぎない。だが、囲碁というゲームの複雑さや、先を読むことの難しさを思うと、ここまでの囲碁用AIが作れたことには、感嘆を禁じえない。囲碁は、ゲーム理論の世界では「二人ゼロサム有限確定完全情報ゲーム」と呼ばれる。意思決定に関わる情報のすべてが盤面に存在するため、コンピュータにとっては比較的与し易いものとされ、AI研究の初期から研究が続けられてきた。それでも囲碁と将棋は難しく、プロに確実に勝つソフトを作るのは、一つの目標とされてきた。(本文より)小寺・西田の「金曜ランチビュッフェ　はこちらから→http://yakan-hiko.com/kode-nishi.html

Literary Theory for Robots reveals the hidden history of modern machine intelligence, taking listeners on a spellbinding journey from medieval Arabic philosophy to visions of a universal language, past Hollywood fiction factories, and missile defense systems trained on Russian folktales. In this provocative reflection on the shared pasts of literature and computer science, former Microsoft engineer and professor of comparative literature Dennis Yi Tenen provides crucial context for recent developments in AI, which holds important lessons for the future of humans living with smart technology.

PLAYING WITH REALITY explores the riveting history of games since the Enlightenment, weaving an unexpected path through military theory, biology, artificial intelligence, neuroscience, cognitive psychology, and the future of democracy. As neuroscientist and physicist Kelly Clancy shows us, games have been deeply intertwined with the arc of history. War games shaped the outcomes of real wars in nineteenth and twentieth century Europe. Game theory warped our understanding of human behavior and brought us to the brink of annihilation.

En Nexus, Harari contempla a la humanidad desde la amplia perspectiva de la historia para analizar cómo las redes de información han hecho y deshecho nuestro mundo. Durante los últimos 100.000 años, los sapiens hemos acumulado un enorme poder. Pero, a pesar de todos los descubrimientos, inventos y conquistas, ahora nos enfrentamos a una crisis existencial: el mundo está al borde del colapso ecológico, abunda la desinformación y nos precipitamos hacia la era de la I.A. Con todo el camino andando, ¿por qué somos una especie autodestructiva?

In this updated and expanded edition of Human + Machine—including a new chapter on gen AI—Daugherty and Wilson show that the essence of the AI paradigm shift is the transformation of all business processes within an organization, whether related to breakthrough innovation, everyday customer service, or personal productivity habits. As humans and smart machines collaborate ever more closely, work processes become more fluid and adaptive, enabling companies to change them on the fly—or completely reimagine them.
