Understanding and implementing them can be daunting. Curious learners and industrial developers can find these complex, especially if they focus on the detailed implementation of these data structures. Clojure is a highly pragmatic and expressive language with efficient and easy data manipulation capabilities. As such, it is great for implementing these algorithms. By abstracting away a great share of the unnecessary complexity resulting from implementation, Clojure and its contrib libraries will help you address various algorithmic challenges, making your data exploration both profitable and enjoyable. Through 25 recipes, you'll explore advanced algorithms and data-structures, well served by a sound Clojure implementation. This book opens with an exploration of alternative uses of the array data-structure, covering LZ77 compression, drawing fractals using Pascal's triangles, simulating a multi-threaded program execution, and implementing a call-stack winding and un-winding operations. The book elaborates on linked lists, showing you how to construct doubly linked ones, speed up search times over the elements of such structures, use a linked-list as the foundation of a shift-reduce parser, and implement an immutable linked-list using skew binary numbers representation. After that, the tree data-structure is explored, focusing on building self-balancing Splay Trees, designing a B-Tree backing-up an efficient key-value data-store, constructing an undo capable Rope, and showing how Tries can make for an auto-completing facility. Next, some optimization and machine learning techniques are discussed, namely for building a co-occurrence-based recommendation engine, using branch-and-bound to optimize integral cost and profit problems, using Dijkstra's algorithm to determine optimal paths and summarizing texts using the LexRank algorithm. Particular attention is given to logic programming, you will learn to use this to discover interesting relations between social website data, by designing a simple type inferencer for a mini Java-like language, and by building a simple checkers game engine. Asynchronous programming will be addressed and you will design a concurrent web-crawler, an interactive HTML5 game, and an online taxi booking platform. Finally, you'll explore advanced cases for higher order functions in Clojure while implementing a recursive descent parser using efficient mutual resucrsion, devising a mini resusable firewall simulator thanks to Clojure 1.7 new tansducers feature or building a simple unification engine with the help of Continuation Passing Style.

Closer: Performance, Technologies, Phenomenology

by Susan Kozel

In Closer, Susan Kozel draws on live performance practice, digital technologies, and the philosophical approach of phenomenology. Trained in dance and philosophy, Kozel places the human body at the center of explorations of interactive interfaces, responsive systems, and affective computing, asking what can be discovered as we become closer to our computers--as they become extensions of our ways of thinking, moving, and touching. Performance, Kozel argues, can act as a catalyst for understanding wider social and cultural uses of digital technology. Taking this one step further, performative acts of sharing the body through our digital devices foster a collaborative construction of new physical states, levels of conscious awareness, and even ethics. We re-encounter ourselves and others through our interactive computer systems. What we need now are conceptual and methodological frameworks to reflect this. Kozel offers a timely reworking of the phenomenology of French philosopher Maurice Merleau-Ponty. This method, based on a respect for lived experience, begins by listening to the senses and noting insights that arrive in the midst of dance, or quite simply in the midst of life. The combination of performance and phenomenology offered by Closer yields entwinements between experience and reflection that shed light on, problematize, or restructure scholarly approaches to human bodies using digital technologies. After outlining her approach and methodology and clarifying the key concepts of performance, technologies, and virtuality, Kozel applies phenomenological method to the experience of designing and performing in a range of computational systems: telematics, motion capture, responsive architectures, and wearable computing. The transformative potential of the alchemy between bodies and technologies is the foundation of Closer. With careful design, future generations of responsive systems and mobile devices can expand our social, physical, and emotional exchanges.

Cloud Bibliography

by Safari Content Team

One of the greatest changes in the computing world has been the move to using common, distributed hardware and software to support services, coined cloud computing. We have chosen a selection of the most useful books in cloud computing within this bibliography. First we look at the basics and some of the key concepts and issues that arise in Cloud computing in general. Then we examine how the 'as a service' (aaS) has helped to drive and expand the reach of the cloud deployment environment. Next, the role of different cloud services, both internal to support cloud operations, and externally provided as a part of the web of cloud operational support are covered. Virtualization, the effective division of computing to more essential computing units has helped to make broad-spectrum web services effective and distributed, and is another key driver behind understanding the cloud. Combining both cloud services and existing datacenters is the role of the Hybrid cloud, aiming to take advantage of the best of both worlds. An array of cloud deployment and development platforms are described, covering both public and private cloud services. Throughout the cloud environment security is a major concern, especially when sharing and distributing user and customer data. Finally, the role of development tools and environments are examined, covering both key tools and entire development stacks. So, be sure to take advantage of the books and videos on cloud computing that you will find in the Safari Books Online library.
