How does coding change the way we think about architecture? This question opens up an important research perspective. In this book, Miro Roman and his AI Alice_ch3n81 develop a playful scenario in which they propose coding as the new literacy of information. They convey knowledge in the form of a project model that links the fields of architecture and information through two interwoven narrative strands in an “infinite flow” of real books. Focusing on the intersection of information technology and architectural formulation, the authors create an evolving intellectual reflection on digital architecture and computer science.

Film noir is more than a cinematic genre. It is an essential aspect of American culture. Along with the cowboy of the Wild West, the denizen of the film noir city is at the very center of our mythological iconography. Described as the style of an anxious victor, film noir began during the post-war period, a strange time of hope and optimism mixed with fear and even paranoia. The shadow of this rich and powerful cinematic style can now be seen in virtually every artistic medium. The spectacular success of recent neo-film noirs is only the tip of an iceberg. In the dead-on, nocturnal jazz of Charlie Parker and Miles Davis, the chilled urban landscapes of Edward Hopper, and postwar literary fiction from Nelson Algren and William S. Burroughs to pulp masters like Horace McCoy, we find an unsettling recognition of the dark hollowness beneath the surface of the American Dream. Acclaimed novelist and poet Nicholas Christopher explores the cultural identity of film noir in a seamless, elegant, and enchanting work of literary prose. Examining virtually the entire catalogue of film noir, Christopher identifies the central motif as the urban labyrinth, a place infested with psychosis, anxiety, and existential dread in which the noir hero embarks on a dangerously illuminating quest. With acute sensitivity, he shows how technical devices such as lighting, voice over, and editing tempo are deployed to create the film noir world. Somewhere in the Night guides us through the architecture of this imaginary world, be it shot in New York or Los Angeles, relating its elements to the ancient cultural archetypes that prefigure it. Finally, Christopher builds an explanation of why film noir not only lives on but is currently enjoying a renaissance. Somewhere in the Night can be appreciated as a lucid introduction to a fundamental style of American culture, and also as a guide to film noir's heyday. Ultimately, though, as the work of a bold talent adeptly manipulating poetic cadence and metaphor, it is itself a superb aesthetic artifact.
Accelerate your development process using Drupal 8 Views with this advanced, practical guide About This Book A practical, step-by-step guide with illustrative examples to give you a clear understanding of Drupal 8 views Get the only book on the market that talks about Drupal 8 views and their importance for developers Get an understanding of how views work and how they help to create modular applications Who This Book Is For This book is for web developers, web designers, and website administrators who use Drupal 8, have some basic knowledge of managing and developing apps with Drupal, and who want to get an advanced, practical knowledge of views and how to leverage them in Drupal 8 applications. What You Will Learn Create displays of content that are automatically updated when you add new content Show maps and rotating image carousels on your site Combine content to create composite displays using the same data in different ways Use fields from more than one content type to create powerful views of multi-table data Modify the field data being displayed, combining it in different ways or changing the HTML that might be normally generated Add headers and footers above and below a views display Make the output of your view look exactly like the designer specifies Change the order in which a list of content is displayed, limit the content shown to only certain content types or values Filter content using values passed to the view in the URL, making a single view work different ways In Detail Learn how to build complex displays of content—all without programming. Views were used on more than 80% of all Drupal 7 sites; now they are part of the Drupal 8 core. While most site builders and site owners are aware of views, they don't understand how to take full advantage of their power to create many amazing pages and blocks. If they use views, they might build 10 different view displays with different filters, without knowing that a contextual filter would require only a single display. Using our sample company, we'll take its existing content and evolve an ever more complex and powerful website for that company, starting with adapting the administration the user sees and moving on to making complex pages of information for site visitors. While the book is written for Drupal 8, the similarities between Views in Drupal 7 and 8 make this a useful reference for Drupal 7 site builders also. Style and approach This is the only advanced resource that will show you how to create, customize, and manage views in the Drupal 8 development environment. This has become more important since Drupal 8 has made views part of its core architecture.
