Book Description
Let M be a smooth manifold and G a Lie group. In this book we shall study infinite-dimensional Lie algebras associated both to the group Map(M, G) of smooth mappings from M to G and to the group of dif feomorphisms of M. In the former case the Lie algebra of the group is the algebra Mg of smooth mappings from M to the Lie algebra gof G. In the latter case the Lie algebra is the algebra Vect M of smooth vector fields on M. However, it turns out that in many applications to field theory and statistical physics one must deal with certain extensions of the above mentioned Lie algebras. In the simplest case M is the unit circle SI, G is a simple finite dimensional Lie group and the central extension of Map( SI, g) is an affine Kac-Moody algebra. The highest weight theory of finite dimensional Lie algebras can be extended to the case of an affine Lie algebra. The important point is that Map(Sl, g) can be split to positive and negative Fourier modes and the finite-dimensional piece g corre sponding to the zero mode.

Book Description
Akka solves the big problems of distributed systems, from multithreading and concurrency to scalability and failure. Learn how to use it effectively. In Akka in Action, Second Edition you will learn how to: Create basic programs with Akka Typed Work with clusters to build robust, fault-tolerant programs Use Akka with Kubernetes Build microservices with Akka Create and maintain distributed state with strong consistency guarantees Employ actor-based concurrency and parallelism Test Akka software Akka in Action, Second Edition teaches you to use Akka Typed to solve common problems of distributed systems. You’ll learn how to bring together all of Akka’s moving parts to design and implement highly scalable and maintainable software. Extensively revised by Akka contributor Francisco López-Sancho Abraham, this new edition demonstrates Akka’s complex concepts through engaging hands-on examples. Discover the power of the Actor Model, how Akka works with Kubernetes, and how to utilize Akka modules to create microservices that are reliable and fault tolerant. About the technology For large software systems, the action is in the “-ilities.” Scalability. Reliability. Maintainability. Capability. Akka, toolkit for building distributed message-driven applications, delivers on the “ilities.” And recent innovations, including Akka Typed, ensure that this amazing platform will remain the best way to build and deploy distributed Java and Scala applications for years to come. About the book Akka in Action, Second Edition is your guide to building message-centric distributed applications systems. This new edition covers all features of Akka, including Akka Typed. You’ll learn to create microservices using Akka’s powerful suite of tools, Akka Sharding, Persistence, Streams, Persistence Query, Projections, and gRPC. Practical examples taken directly from industry guide you through clustering, deploying to Kubernetes, and taking full advantage of Akka’s Actors-based approach to concurrency. What's inside Work with clusters to build robust, fault-tolerant programs Maintain distributed systems with strong consistency guarantees Utilize concurrency and parallelism Test Akka software About the reader For readers comfortable with Java and Scala. About the author Francisco Lopez Sancho-Abraham is a senior consultant at Lightbend, and a principal engineer on the Akka Team. Raymond Roestenburg, Rob Bakker, and Rob Williams are the authors of the first edition of Akka in Action.

Book Description
One of a firm's most valuable resources is its data: client lists, accounting data, employee information, and so on. This critical data must be securely managed and controlled, and simultaneously made available to those users authorized to see it. The IBM® z/VSE® system features extensive capabilities to simultaneously share the firm's data among multiple users and protect them. Threats to this data come from various sources. Insider threats and malicious hackers are not only difficult to detect and prevent, they might be using resources with the business being unaware. This IBM Redbooks® publication was written to assist z/VSE support and security personnel in providing the enterprise with a safe, secure and manageable environment. This book provides an overview of the security that is provided by z/VSE and the processes for the implementation and configuration of z/VSE security components, Basic Security Manager (BSM), IBM CICS® security, TCP/IP security, single sign-on using LDAP, and connector security.
