Now it is time to focus on real-life problems that are high-dimensional or ill-defined, for example, due to delay, spatial extent, stochasticity, or the limited nature of available data. Written by international experts, Nonlinear Dynamics and Chaos: Where Do We Go from Here? assesses what the future holds for dynamics and chaos. The chapters address one or more of the broad and interconnected main themes: neural and biological systems, spatially extended systems, and experimentation in the physical sciences. The contributors offer suggestions as to what they see as the way forward, often in the form of open questions for future research.

"Your organization needs this book!"
--Peter Salus, Chief Knowledge Officer, Matrix.Net, "The Bookworm"

This book describes the best practices of system and network administration, independent of specific platforms or technologies. It features six key principles of site design and support practices: simplicity, clarity, generality, automation, communication, and basics first. It examines the major areas of responsibility for system administrators within the context of these principles. The book also discusses change management and revision control, server upgrades, maintenance windows, and service conversions. You will find experience-based advice on topics such as:

• The key elements your networks/systems need that will make all other services run better
• Building and running reliable, scalable services, including email, printing, and remote access
• Creating security policies and enforcing them
• Upgrading thousands of hosts without creating havoc
• Planning for and performing flawless scheduled maintenance windows
• Superior helpdesks, customer care, and avoiding the temporary fix trap
• Building data centers that prevent problems
• Designing networks for speed and reliability
• Email scaling and security issues
• Why building a backup system isn't about backups
• Monitoring what you have and predicting what you will need
• How to stay technical and how not to be pushed into management

And there's more! When was the last time you read a book that dealt with:

• Real-world technical management issues, including morale, organization building, coaching, maintaining positive visibility, and communicating with nontechnical management
• Personal skill techniques, including our secrets for getting more done each day, dealing with less technical people, ethical dilemmas, managing your boss, and loving your job
• System administration salary negotiation tips--the first book that includes this topic!

Chapters are divided into The Basics and The Icing. The Basics are those key elements that, when done right, make every other aspect of the job easier. Things like starting all new hosts with the same configuration and picking the right things to automate first. The Icing sections contain all those powerful things that can be done on top of the basics to wow customers and managers. Do the basics first. The icing is a vision for the future that usually only comes with decades of experience.

Desde el comienzo de la civilización, el ser humano se ha preguntado acerca de su lugar en el cosmos y sobre el origen de éste. En la actualidad, como explica claramente este sencillo volumen, disponemos de un modelo sólido sobre el origen del universo: el Big Bang, completado con la idea de la inflación cósmica. Centrándose en las ideas clave y evitando detalles técnicos que atañen sólo a los especialistas, Craig J. Hogan ofrece el relato moderno de la evolución cósmica, exponiendo en EL LIBRO DEL BIG BANG de forma sumaria, pero rigurosa y precisa, el hito fundamental de la cosmología: un conjunto de ideas teóricas capaz de explicar no sólo el origen y la abundancia de los elementos que constituyen el universo, sino también de hacer un conjunto de predicciones que, día a día, la astrofísica actual va verificando.

Todo lo que realmente se requiere para jugar un buen golf es ejecutar un número relativamente pequeño de verdaderos movimientos fundamentales.
El swing de golf que se describe en estas lecciones es la esencia del movimiento reducido a sus fundamentos que son todo lo que necesita el jugador para desarrollar un swing correcto y potente que podrá repetir una y otra vez.
Los fundamentos del golf se agrupan en cuatro puntos:
-el grip que es el pulso de la acción del swing de golf,
-la colocación y la postura,
-la primera parte del swing (desde la colocación inicial hasta el alto de la subida), y
-la segunda parte del swing (desde el inicio de la bajada hasta el finish).
Ben Hogan tenía un swing que era considerado perfecto. Ganó 63 torneos profesionales por lo que es considerado como uno de los mejores golfistas de la historia.
