| centos book: Sorted Books Nina Katchadourian, 2013-02-08 A witty and thought-provoking collection of visual poems constructed from stacks of books. Delighting in the look and feel of books, conceptual artist Nina Katchadourian’s playful photographic series proves that books’ covers—or more specifically, their spines—can speak volumes. Over the past two decades, Katchadourian has perused libraries across the globe, selecting, stacking, and photographing groupings of two, three, four, or five books so that their titles can be read as sentences, creating whimsical narratives from the text found there. Thought-provoking, clever, and at times laugh-out-loud funny (one cluster of titles from the Akron Museum of Art’s research library consists of: Primitive Art /Just Imagine/Picasso/Raised by Wolves), Sorted Books is an enthralling collection of visual poems full of wry wit and bookish smarts. Praise for Sorted Books “Katchadourian’s project . . . takes on a weight beyond its initial novelty. It’s a love letter to books, book collecting and the act of reading.” —San Francisco Chronicle “As a longtime fan of [Katchadourian’s] long-running Sorted Books project I’m thrilled for the release of Sorted Books—a collection spanning nearly two decades of her witty and wise minimalist mediations on life by way of ingeniously arranged book spines. . . . In an era drowned in periodic death tolls for the future of the physical book, her project stands as a celebration of the spirit embedded in the magnificent materiality of the printed page.” —Brain Pickings “Katchadourian’s stacks possess an understated sophistication; they are true to the intimate nature of books and yet reveal their dramatic features and unexpected potential.” —Publishers Weekly |

| centos book: Systems Performance Brendan Gregg, 2013-10-07 The Complete Guide to Optimizing Systems Performance Written by the winner of the 2013 LISA Award for Outstanding Achievement in System Administration Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux® and Unix® performance, while illuminating performance issues that are relevant to all operating systems. You’ll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu®, Fedora®, CentOS, and the illumos-based Joyent® SmartOSTM and OmniTI OmniOS®. He systematically covers modern systems performance, including the “traditional” analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the “unknown unknowns” of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish. Coverage includes • Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques • Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf • Kernel internals: uncovering what the OS is doing • Using system observability tools, interfaces, and frameworks • Understanding and monitoring application performance • Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling • Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators • File system I/O, including caching • Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O • Network-related performance issues: protocols, sockets, interfaces, and physical connections • Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing • Benchmarking: getting accurate results and avoiding common mistakes This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg’s extensive instructional experience. |
