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

With lyrical text and comforting illustrations, Stay Through the Storm is a deeply moving meditation on the power of friendship to carry us through difficult times. When dark clouds gather in the distance, two friends come together to comfort each other through the storm. They shield each other through the rain, make a fort inside, and play games between claps of thunder. Through it all, they come back to a consistent plea: Stay. Stay through the storm.

It is a day in the country, and everthing is hot and still. Then the hazy sky begins to shift. Something is astir, something soundless.

It's the definitive bible on storm chasing, updated in 2008! The Storm Chasing Handbook examines the hobby of storm chasing - the people, the philosophy, and the equipment. Using key findings from the past four decades of scientific literature, readers learn the inner workings of severe weather and dabble with the fundamentals of forecasting techniques, blended with wisdom from the author's own experiences. From target area and storm type prediction to successful, safe navigation, the Storm Chasing Handbook has it covered. A large appendix features a Great Plains travel guide covering local history, culture, meteorology, and geology for nearly 100 chase routes, dining recommendations, broadcast radio and NOAA weather maps, an almanac of past chase seasons, special telephone numbers for reporting severe weather, and a list of recommended videos, books, websites, and references. If you're heading into the field or you just have an interest in severe weather forecasting, Storm Chasing Handbook is the book you can't afford to be without.

Radio astronomy is a mystery to the majority of amateur astronomers, yet it is the best subject to turn to when desirous of an expanded knowledge of the sky. This guide intends to instruct complete newcomers to radio astronomy, and provides help for the first steps on the road towards the study of this fascinating subject. In addition to a history of the science behind the pursuit, directions are included for four easy-to-build projects, based around long-term NASA and Stanford Solar Center projects. The first three projects constitute self-contained units available as kits, so there is no need to hunt around for parts. The fourth – more advanced – project encourages readers to do their own research and track down items. Getting Started in Radio Astronomy provides an overall introduction to listening in on the radio spectrum. With details of equipment that really works, a list of suppliers, lists of online help forums, and written by someone who has actually built and operated the tools described, this book contains everything the newcomer to radio astronomy needs to get going.

A storm and its sunny aftermath come to life through gorgeous art and lyrical text. What do you do when the clouds roll in, When the wind chimes clang and the weather vanes spin? When stormy skies threaten, people stock up on supplies, bring in their outside toys, and check the news for updates. And during the storm, if the power goes out, they can play games and tell stories by candlelight. But what do animals do? They watch and listen, look for a cozy den or some other sheltered spot, and hunker down to wait. After the storm, while the people are cleaning up their yards, making repairs, and checking on the neighbors, the animals emerge from their hiding places and shake off the rain. And everyone is happy to be out in the sunshine again, grateful for better weather and the company of friends.
