What happened to the ancient Egyptians? The Persians? The Romans? The Mayans? ARE WE THEIR DESCENDANTS? Recent genetic discoveries are uncovering surprising links between us and the peoples of old—links that rewrite race, ethnicity, and human history. Today’s Native Americans descend from Central Asians who arrived in the early A.D. era. Abraham, Isaac, and Jacob still have clearly identifiable descendants, albeit rare ones. Every people group on earth can genetically trace their origins to Noah and his three sons.
In most college and university libraries, materials published before 1800 have been moved into special collections, while the post-1923 books remain in general circulation. But books published between these dates are vulnerable to deaccessioning, as libraries increasingly reconfigure access to public-domain texts via digital repositories such as Google Books. Even libraries with strong commitments to their print collections are clearing out the duplicates, assuming that circulating copies of any given nineteenth-century edition are essentially identical to one another. When you look closely, however, you see that they are not. Many nineteenth-century books were donated by alumni or their families decades ago, and many of them bear traces left behind by the people who first owned and used them. In Book Traces, Andrew M. Stauffer adopts what he calls "guided serendipity" as a tactic in pursuit of two goals: first, to read nineteenth-century poetry through the clues and objects earlier readers left in their books and, second, to defend the value of keeping the physical volumes on the shelves. Finding in such books of poetry the inscriptions, annotations, and insertions made by their original owners, and using them as exemplary case studies, Stauffer shows how the physical, historical book enables a modern reader to encounter poetry through the eyes of someone for whom it was personal.
The theory of traces employs techniques and tackles problems from quite diverse areas which include formal language theory, combinatorics, graph theory, algebra, logic, and the theory of concurrent systems. In all these areas the theory of traces has led to interesting problems and significant results. It has made an especially big impact in formal language theory and the theory of concurrent systems. In both these disciplines it is a well-recognized and dynamic research area. Within formal language theory it yields the theory of partially commutative monoids, and provides an important connection between languages and graphs. Within the theory of concurrent systems it provides an important formal framework for the analysis and synthesis of concurrent systems.This monograph covers all important research lines of the theory of traces; each chapter is devoted to one research line and is written by leading experts. The book is organized in such a way that each chapter can be read independently ? and hence it is very suitable for advanced courses or seminars on formal language theory, the theory of concurrent systems, the theory of semigroups, and combinatorics. An extensive bibliography is included. At present, there is no other book of this type on trace theory.
With a New Preface by the Author Through personal journeys and historical inquiry, this PEN Literary Award finalist explores how America’s still unfolding history and ideas of “race” have marked its people and the land. Sand and stone are Earth’s fragmented memory. Each of us, too, is a landscape inscribed by memory and loss. One life–defining lesson Lauret Savoy learned as a young girl was this: the American land did not hate. As an educator and Earth historian, she has tracked the continent’s past from the relics of deep time; but the paths of ancestors toward her—paths of free and enslaved Africans, colonists from Europe, and peoples indigenous to this land—lie largely eroded and lost. A provocative and powerful mosaic that ranges across a continent and across time, from twisted terrain within the San Andreas Fault zone to a South Carolina plantation, from national parks to burial grounds, from “Indian Territory” and the U.S.–Mexico Border to the U.S. capital, Trace grapples with a searing national history to reveal the often unvoiced presence of the past. In distinctive and illuminating prose that is attentive to the rhythms of language and landscapes, she weaves together human stories of migration, silence, and displacement, as epic as the continent they survey, with uplifted mountains, braided streams, and eroded canyons. Gifted with this manifold vision, and graced by a scientific and lyrical diligence, she delves through fragmented histories—natural, personal, cultural—to find shadowy outlines of other stories of place in America. "Every landscape is an accumulation," reads one epigraph. "Life must be lived amidst that which was made before." Courageously and masterfully, Lauret Savoy does so in this beautiful book: she lives there, making sense of this land and its troubled past, reconciling what it means to inhabit terrains of memory—and to be one.

From one of the foremost medievalists of our time, a groundbreaking work on history and memory that goes well beyond the life of this influential saint. Elected bishop of Milan by popular acclaim in 374, Ambrose went on to become one of the four original Doctors of the Church. There is much more to this book, however, than the captivating story of the bishop who baptized Saint Augustine in the fourth century. Trace and Aura investigates how a crucial figure from the past can return in different guises over and over again, in a city that he inspired and shaped through his beliefs and political convictions. His recurring lives actually span more than ten centuries, from the fourth to the sixteenth. In the process of following Ambrose’s various reincarnations, Patrick Boucheron draws compelling connections between religion, government, tyranny, the Italian commune, Milan’s yearning for autonomy, and many other aspects of this fascinating relationship between a city and its spiritual mentor who strangely seems to resist being manipulated by the needs and ambitions of those in power.
"I heard some things about you.... I just wondered if the rumors were true." "Like what?" "Don't you know? I mean, don't you know what's going around?" "Yeah, I know. Who told you?" "I don't want to say- I promised. But... is it true?" I held my breath, surprised at my own boldness. Trace said nothing at first. But I could hear him breathing. Had I made a mistake in asking him? I sat there holding the phone in anticipation, sharing the open line between us. I looked out my bedroom window, past the pink curtains, beyond the safety of all I knew, and stared into the darkness. Finally, Trace spoke. "Yeah. It's true." "It is?" "Yeah. Does that scare you? "No." "Really? Well, it could.... If you knew everything, you might really be afraid." It's 1988 and school is back in session at Fairview High. That means freshly waxed floors, the sound of lockers slamming and bells ringing through the halls. For one student, the challenge of a new school and new friends will be just the beginning of what she faces her freshman year when she meets Trace Erring, an older boy with a dark secret. Pursued by Trace, almost immediately, she is captivated by his mystery as well as his persistence. In her search to learn more about Trace, she soon finds herself drawn into a strange new world, seeking help from an unlikely source.
Understand how to apply distributed tracing to microservices-based architectures Key FeaturesA thorough conceptual introduction to distributed tracingAn exploration of the most important open standards in the spaceA how-to guide for code instrumentation and operating a tracing infrastructureBook Description Mastering Distributed Tracing will equip you to operate and enhance your own tracing infrastructure. Through practical exercises and code examples, you will learn how end-to-end tracing can be used as a powerful application performance management and comprehension tool. The rise of Internet-scale companies, like Google and Amazon, ushered in a new era of distributed systems operating on thousands of nodes across multiple data centers. Microservices increased that complexity, often exponentially. It is harder to debug these systems, track down failures, detect bottlenecks, or even simply understand what is going on. Distributed tracing focuses on solving these problems for complex distributed systems. Today, tracing standards have developed and we have much faster systems, making instrumentation less intrusive and data more valuable. Yuri Shkuro, the creator of Jaeger, a popular open-source distributed tracing system, delivers end-to-end coverage of the field in Mastering Distributed Tracing. Review the history and theoretical foundations of tracing; solve the data gathering problem through code instrumentation, with open standards like OpenTracing, W3C Trace Context, and OpenCensus; and discuss the benefits and applications of a distributed tracing infrastructure for understanding, and profiling, complex systems. What you will learnHow to get started with using a distributed tracing systemHow to get the most value out of end-to-end tracingLearn about open standards in the spaceLearn about code instrumentation and operating a tracing infrastructureLearn where distributed tracing fits into microservices as a core functionWho this book is for Any developer interested in testing large systems will find this book very revealing and in places, surprising. Every microservice architect and developer should have an insight into distributed tracing, and the book will help them on their way. System administrators with some development skills will also benefit. No particular programming language skills are required, although an ability to read Java, while non-essential, will help with the core chapters.
An innovative multidisciplinary study of the relationship between visual perception and temporal meaning in ancient Greek literature and history writing
In a debut novel that's perfect for fans of Jason Reynolds and Erin Entrada Kelly, award-winning author/illustrator and educator Pat Cummings tells a poignant story about grief, love, and the untold stories that echo across time. Trace Carter doesn’t know how to feel at ease in his new life in New York. Even though his artsy Auntie Lea is cool, her brownstone still isn’t his home. Haunted by flashbacks of the accident that killed his parents, the best he can do is try to distract himself from memories of the past. But the past isn’t done with him. When Trace takes a wrong turn in the New York Public Library, he finds someone else lost in the stacks with him: a crying little boy, wearing old, tattered clothes. And though at first he can’t quite believe he’s seen a ghost, Trace soon discovers that the boy he saw has ties to Trace’s own history—and that he himself may be the key to setting the dead to rest.
