Storm Over Java

Meteorology of Hydrologically Critical Storms in California

Getting Started with Storm

Even as big data is turning the world upside down, the next phase of the revolution is already taking shape: real-time data analysis. This hands-on guide introduces you to Storm, a distributed, JVM-based system for processing streaming data. Through simple tutorials, sample Java code, and a complete real-world scenario, you’ll learn how to build fast, fault-tolerant solutions that process results as soon as the data arrives. Discover how easy it is to set up Storm clusters for solving various problems, including continuous data computation, distributed remote procedure calls, and data stream processing. Learn how to program Storm components: spouts for data input and bolts for data transformation Discover how data is exchanged between spouts and bolts in a Storm topology Make spouts fault-tolerant with several commonly used design strategies Explore bolts—their life cycle, strategies for design, and ways to implement them Scale your solution by defining each component’s level of parallelism Study a real-time web analytics system built with Node.js, a Redis server, and a Storm topology Write spouts and bolts with non-JVM languages such as Python, Ruby, and Javascript

Silenced Voices

Like a number of Netherlanders in the post-World War II era, Inez Hollander only gradually became aware of her family's connections with its Dutch colonial past, including a Creole great-grandmother. For the most part, such personal stories have been, if not entirely silenced, at least only whispered about in Holland, where society has remained uncomfortable with many aspects of the country's relationship with its colonial empire. Unlike the majority of memoirs that are soaked in nostalgia for tempo dulu, Hollander's story sets out to come to grips with her family's past by weaving together personal records with historical and literary accounts of the period. She seeks not merely to locate and preserve family memories, but also to test them against a more disinterested historical record. Hers is a complicated and sometimes painful personal journey of realization, unusually mindful of the ways in which past memories and present considerations can be intermingled when we seek to understand a difficult past. Silenced Voices is an important contribution to the literature on how Dutch society has dealt with its recent colonial history.
