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. A story to bring hope in times of trouble, Stay Through the Storm is a moving reminder that we're never alone even when things seem darkest.

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.

Storm in the night. Thunder like mountains blowing up. Lightning licking the navy-blue sky. Rain streaming down the windows, babbling in the downspouts. And Grandfather? . . . And Thomas? . . . And Ringo, the cat? They were in the dark. Too early to go to bed, and with only flashes of lightning to see by, Thomas and his grandfather happily find themselves re-discovering the half-forgotten scents and sounds of their world, and having a wonderful time learning important, new things about each other in a spirited conversation sparked by darkness. Mary Stolz and Pat Cummings have each brought their unique talents to this lyrical tale about a magical, stormy night and a special relationship.

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.

Lin and Larry Pardey demonstrate methods to help you bring your boat and crew safely through storms. Join them near South Africa's Cape of Storms to watch a live demonstration of setting and retrieving a para-anchor, then sail on board Taleisin during Lin & Larry's rounding of Cape Horn with storm sails in action in 70-knot winds. They demonstrate techincal details of storm tactics for both modern and classic boats. Learn how to prepare your crew and boat to eliminate fear and face heavy weather with a plan. Learn how and when to use the sailor's safety valve, heaving-to, with or without a para-anchor. They also discuss gear and equipment, plus special sails for heavy weather.
