Universos paralelos
by Ricardo HomsLa tecnología informática le han dado a los medios masivos de la comunicación una gran capacidad de convocatoria para unir los consensos de sectores sociales y políticos y, de esta manera, incidir enormemente en la opinión pública. Con esto, sin que estemos conscientes, nos han impuesto los temas que ahora son prioritarios para la sociedad. Universos paralelos nos ofrece una versión de cómo se han conformado, a partir de la tecnología virtual y la globalización, fuerzas ocultas que quieren controlar nuestro estilo de la vida y nuestra mente, y muestra también cómo se han constituido poderes fácticos que deciden en qué clase de mundo debemos vivir. En los últimos años, sin darnos cuenta, hemos vivido en dos mundos: el de nuestra vida cotidiana, y en uno paralelo que no tiene control, que es invisible, pero determinante.
UNIX: The Textbook, Third Edition
by Syed Mansoor Sarwar Robert M. KoretskyUNIX: The Textbook, Third Edition provides a comprehensive introduction to the modern, twenty-first-century UNIX operating system. The book deploys PC-BSD and Solaris, representative systems of the major branches of the UNIX family, to illustrate the key concepts. It covers many topics not covered in older, more traditional textbook approaches, such as Python, UNIX System Programming from basics to socket-based network programming using the client-server paradigm, the Zettabyte File System (ZFS), and the highly developed X Windows-based KDE and Gnome GUI desktop environments. The third edition has been fully updated and expanded, with extensive revisions throughout. It features a new tutorial chapter on the Python programming language and its use in UNIX, as well as a complete tutorial on the git command with Github. It includes four new chapters on UNIX system programming and the UNIX API, which describe the use of the UNIX system call interface for file processing, process management, signal handling, interprocess communication (using pipes, FIFOs, and sockets), extensive coverage of internetworking with UNIX TCP/IP using the client-server software, and considerations for the design and implementation of production-quality client-server software using iterative and concurrent servers. It also includes new chapters on UNIX system administration, ZFS, and container virtualization methodologies using iocage, Solaris Jails, and VirtualBox. Utilizing the authors’ almost 65 years of practical teaching experience at the college level, this textbook presents well-thought-out sequencing of old and new topics, well-developed and timely lessons, a Github site containing all of the code in the book plus exercise solutions, and homework exercises/problems synchronized with the didactic sequencing of chapters in the book. With the exception of four chapters on system programming, the book can be used very successfully by a complete novice, as well as by an experienced UNIX system user, in both an informal and formal learning environment. The book may be used in several computer science and information technology courses, including UNIX for beginners and advanced users, shell and Python scripting, UNIX system programming, UNIX network programming, and UNIX system administration. It may also be used as a companion to the undergraduate and graduate level courses on operating system concepts and principles.

Unjust: Social Justice and the Unmaking of America
by Noah Rothman"An elegant and thoughtful dismantling of perhaps the most dangerous ideology at work today." — BEN SHAPIRO, bestselling author and host of "The Ben Shapiro Show" "Reading Noah Rothman is like a workout for your brain." — DANA PERINO, bestselling author and former press secretary to President George W. Bush There are just two problems with “social justice”: it’s not social and it’s not just. Rather, it is a toxic ideology that encourages division, anger, and vengeance. In this penetrating work, Commentary editor and MSNBC contributor Noah Rothman uncovers the real motives behind the social justice movement and explains why, despite its occasionally ludicrous public face, it is a threat to be taken seriously. American political parties were once defined by their ideals. That idealism, however, is now imperiled by an obsession with the demographic categories of race, sex, ethnicity, and sexual orientation, which supposedly constitute a person’s “identity.” As interest groups defined by identity alone command the comprehensive allegiance of their members, ordinary politics gives way to “Identitarian” warfare, each group looking for payback and convinced that if it is to rise, another group must fall. In a society governed by “social justice,” the most coveted status is victimhood, which people will go to absurd lengths to attain. But the real victims in such a regime are blind justice—the standard of impartiality that we once took for granted—and free speech. These hallmarks of American liberty, already gravely compromised in universities, corporations, and the media, are under attack in our legal and political systems.
The Unknown Component Problem
by Alberto Sangiovanni-Vincentelli Alan Mishchenko Alexandre Petrenko Tiziano Villa Robert K. Brayton Nina YevtushenkoThe Problem of the Unknown Component: Theory and Applications addresses the issue of designing a component that, combined with a known part of a system, conforms to an overall specification. The authors tackle this problem by solving abstract equations over a language. The most general solutions are studied when both synchronous and parallel composition operators are used. The abstract equations are specialized to languages associated with important classes of automata used for modeling systems. The book is a blend of theory and practice, which includes a description of a software package with applications to sequential synthesis of finite state machines. Specific topologies interconnecting the components, exact and heuristic techniques, and optimization scenarios are studied. Finally the scope is enlarged to domains like testing, supervisory control, game theory and synthesis for special omega languages. The authors present original results of the authors along with an overview of existing ones.
