Observability is critical for building, changing, and understanding the software that powers complex modern systems. Teams that adopt observability are much better equipped to ship code swiftly and confidently, identify outliers and aberrant behaviors, and understand the experience of each and every user. This practical book explains the value of observable systems and shows you how to practice observability-driven development. Authors Charity Majors, Liz Fong-Jones, and George Miranda from Honeycomb explain what constitutes good observability, show you how to improve upon what youâ??re doing today, and provide practical dos and don'ts for migrating from legacy tooling, such as metrics, monitoring, and log management. Youâ??ll also learn the impact observability has on organizational culture (and vice versa). You'll explore: How the concept of observability applies to managing software at scale The value of practicing observability when delivering complex cloud native applications and systems The impact observability has across the entire software development lifecycle How and why different functional teams use observability with service-level objectives How to instrument your code to help future engineers understand the code you wrote today How to produce quality code for context-aware system debugging and maintenance How data-rich analytics can help you debug elusive issues

The wit and wisdom of one of our greatest military leaders in a compact, highly readable edition!

Letters by George S. Patton

"I don't know what a Philadelphia lawyer might say, but I know what I mean by Country. It is the Constitution! 'Just the greatest document ever written by man' according to an English Prime Minister. You know why we serve the Constitution? Simple! Recall what you said when you got your first commission or got a promotion. You take an oath to God 'to support the Constitution against all enemies foreign and domestic.' We are fighting for our great Constitution. We are not fighting for any man, president, senator, congressman nor potentate. This is what I mean by Country."

--General George S. Patton

Hydrogen offers a promising alternative for supplying clean and sustainable energy to meet increasing demands worldwide. However, materials are key to transforming the technology into a viable industry. Materials for the Hydrogen Economy describes the technical challenges and the current efforts in developing materials possessing the properties required for handling each stage of the hydrogen fuel chain. Thorough coverage offers newcomers as well as experienced engineers and researchers a reliable and fully scalable foundation in this field. This book covers all seven of the current hydrogen production methods, as well as distribution, storage, and utilization technologies, particularly fuel cells. It details the chemical reactions, processes, types of feedstock, and commercial equipment involved in hydrogen production. It also covers methods, membranes, liners, and sensors used for separating, sealing, and purifying hydrogen. Several chapters examine corrosion effects in pipeline steels and other storage and transportation vessels, leading to discussions of hydrogen permeation barriers, barrier coatings, and hydrides for on-board hydrogen storage. The final chapters focus on electrolytes and component materials for solid-oxide fuel cells (SOFCs) and H2/O2 PEM fuel cells. Materials for the Hydrogen Economy provides a broad review of material requirements for handling hydrogen from production to market. It explores the development of these materials alongside essential considerations and issues associated with their deployment.

The publications of the Hakluyt Society (founded in 1846) made available edited (and sometimes translated) early accounts of exploration. The first series, which ran from 1847 to 1899, consists of 100 books containing published or previously unpublished works by authors from Christopher Columbus to Sir Francis Drake, and covering voyages to the New World, to China and Japan, to Russia and to Africa and India. This 1863 volume contains a Victorian translation of Ludovico di Varthema's account of his travels, originally published in 1510, and translated into many European languages within a few years. Ludovico set off from Italy in 1502 (determined, he says, 'to investigate some small portion of this our terrestrial globe') and travelled first to Egypt and Syria; he then journeyed through the Arabian peninsula (where he was imprisoned as a spy), Persia and India, and reached the Molucca islands before returning to Europe in 1508.

"The life, work and activism of Rocky Jones are central to African-Canadian history and the civil rights movement in Canada. Canadians lost a great soul, with the recent death of Rocky Jones, but his autobiography - co-written by James Walker, a close friend of Rocky Jones and one of our foremost writers about Black history in Canada - is a wonderful gift to the entire country. Revolutionary will soon be required reading for any person who seeks to understand the civil rights movement in Canada." - Lawrence Hill "A must read, a manual for all freedom fighters, and a testament to Rocky Jones' and Black power and resilience." -- Afua Cooper "Any telling of human rights and social equity in Canada would be incomplete without reference to "revolutionary" Rocky Jones' truth-telling about his life captured in this compelling exemplary autobiography. This insightful account is not only about life as an African Nova Scotian, but also about the community, law, politics." -- Carl James Born and raised in Truro, Nova Scotia, Burnley "Rocky" Jones is one of Canada's most important figures of social justice. Often referred to as Canada's Stokely Carmichael, Jones was tirelessly dedicated to student movements, peace activism, Black Power, anti-racism, women's liberation and human rights reform. He was a leader in the Student Nonviolent Coordinating Committee, brought the Black Panthers to Canada, taught at Dalhousie and founded his own law firm. This autobiography tells the story of Jones's inimitable life and his accomplishments. But it also does more. It illuminates the Black experience in Nova Scotia, it explains the evolving nature of race relations and human rights in recent Canadian history, and it reveals the origins of the "remedial" approach to racial equality that is now practised by activists and governments. Finally, the story of Rocky Jones is a reminder that human rights are not a gift, but a prize that must be fought for.

Nintendo's hugely popular and influential video game console system considered as technological device and social phenomenon. The Nintendo Wii, introduced in 2006, helped usher in a moment of retro-reinvention in video game play. This hugely popular console system, codenamed Revolution during development, signaled a turn away from fully immersive, time-consuming MMORPGs or forty-hour FPS games and back toward family fun in the living room. Players using the wireless motion-sensitive controller (the Wii Remote, or "Wiimote") play with their whole bodies, waving, swinging, swaying. The mimetic interface shifts attention from what's on the screen to what's happening in physical space. This book describes the Wii's impact in technological, social, and cultural terms, examining the Wii as a system of interrelated hardware and software that was consciously designed to promote social play in physical space. Each chapter of Codename Revolution focuses on a major component of the Wii as a platform: the console itself, designed to be low-powered and nimble; the iconic Wii Remote; Wii Fit Plus, and its controller, the Wii Balance Board; the Wii Channels interface and Nintendo's distribution system; and the Wii as a social platform that not only affords multiplayer options but also encourages social interaction in shared physical space. Finally, the authors connect the Wii's revolution in mimetic interface gaming-which eventually led to the release of Sony's Move and Microsoft's Kinect-to some of the economic and technological conditions that influence the possibility of making something new in this arena of computing and culture.

2016 Best Book Award, North American Society for the Sociology of Sport A human face on the realities of professional football, from the challenges players face after leaving the NFL to the factors that can enable them to continue to find success Is There Life After Football? draws upon the experiences of hundreds of former players as they describe their lives playing the sport and after their football days are over. The "bubble"-like conditions of privilege that NFL players experience while playing, often leave players unprepared for the real world once they retire and must manage their own lives. The book also reveals the difficulties affecting former NFL players in retirement: social isolation, financial concerns, inadequate career planning, psychological challenges, and physical injuries. From players who make reckless and unsustainable financial investments during their very few high-earning years, to players who struggle to form personal and professional relationships outside of football, the stories in the book put a very human face on the realities of professional football. George Koonce Jr., a former NFL player himself, weaves in his own story throughout, explaining the challenges he encountered and decisions that helped him succeed after leaving the sport. Ultimately, Is There Life After Football? concludes that, despite the challenges players face, it is possible for players to find success after leaving the NFL if they have the right support, education, and awareness of what might await them.
