Apache Ignite is one of the most widely used open source memory-centric distributed, caching, and processing platform. This allows the users to use the platform as an in-memory computing framework or a full functional persistence data stores with SQL and ACID transaction support. On the other hand, Apache Ignite can be used for accelerating existing Relational and NoSQL databases, processing events & streaming data or developing Microservices in fault-tolerant fashion. This book addressed anyone interested in learning in-memory computing and distributed database. This book intends to provide someone with little to no experience of Apache Ignite with an opportunity to learn how to use this platform effectively from scratch taking a practical hands-on approach to learning. Please see the table of contents for more details.

The full spectrum of industry sectors that will benefit from this technology include, but are not limited to, in-memory and traditional databases, AI, analytics, HPC, virtualization, and big data. Programming Persistent Memory describes the technology and why it is exciting the industry. It covers the operating system and hardware requirements as well as how to create development environments using emulated or real persistent memory hardware. The book explains fundamental concepts; provides an introduction to persistent memory programming APIs for C, C++, JavaScript, and other languages; discusses RMDA with persistent memory; reviews security features; and presents many examples. Source code and examples that you can run on your own systems are included. What You’ll Learn Understand what persistent memory is, what it does, and the value it brings to the industry Become familiar with the operating system and hardware requirements to use persistent memory Know the fundamentals of persistent memory programming: why it is different from current programming methods, and what developers need to keep in mind when programming for persistence Look at persistent memory application development by example using the Persistent Memory Development Kit (PMDK)Design and optimize data structures for persistent memoryStudy how real-world applications are modified to leverage persistent memoryUtilize the tools available for persistent memory programming, application performance profiling, and debugging Who This Book Is For C, C++, Java, and Python developers, but will also be useful to software, cloud, and hardware architects across a broad spectrum of sectors, including cloud service providers, independent software vendors, high performance compute, artificial intelligence, data analytics, big data, etc.

In February 1861, the twelve-year-old son of Arizona rancher John Ward was kidnapped by Apaches. What followed would ignite a Southwestern frontier war between the Chiricahuas and the US Army that would last twenty-five years. In the days following the initial melee, innocent passersby would be taken as hostages on both sides, and almost all of them would be brutally slaughtered. Thousands of lives would be lost, the economies of Arizona and New Mexico would be devastated, and in the end, the Chiricahua way of life would essentially cease to exist. In a gripping narrative that often reads like an old-fashioned Western novel, Terry Mort explores the collision of these two radically different cultures in a masterful account of one of the bloodiest conflicts in our frontier history.

In the early morning of November 29, 1864, with the fate of the Union still uncertain, part of the First Colorado and nearly all of the Third Colorado volunteer regiments, commanded by Colonel John Chivington, surprised hundreds of Cheyenne and Arapaho people camped on the banks of Sand Creek in southeastern Colorado Territory. More than 150 Native Americans were slaughtered, the vast majority of them women, children, and the elderly, making it one of the most infamous cases of state-sponsored violence in U.S. history. A Misplaced Massacre examines the ways in which generations of Americans have struggled to come to terms with the meaning of both the attack and its aftermath, most publicly at the 2007 opening of the Sand Creek Massacre National Historic Site. This site opened after a long and remarkably contentious planning process. Native Americans, Colorado ranchers, scholars, Park Service employees, and politicians alternately argued and allied with one another around the question of whether the nation’s crimes, as well as its achievements, should be memorialized. Ari Kelman unearths the stories of those who lived through the atrocity, as well as those who grappled with its troubling legacy, to reveal how the intertwined histories of the conquest and colonization of the American West and the U.S. Civil War left enduring national scars. Combining painstaking research with storytelling worthy of a novel, A Misplaced Massacre probes the intersection of history and memory, laying bare the ways differing groups of Americans come to know a shared past.
