Akka uses Actors-independently executing processes that communicate via message passing—as the foundation for fault-tolerant applications where individual actors can fail without crashing everything. Perfect for high-volume applications that need to scale rapidly, Akka is an efficient foundation for event-driven systems that want to scale elastically up and out on demand, both on multi-core processors and across server nodes.Akka in Action is a comprehensive tutorial on building message-oriented systems using Akka. The book takes a hands-on approach, where each new concept is followed by an example that shows you how it works, how to implement the code, and how to (unit) test it. You'll learn to test and deploy an actor system and scale it up and out, showing off Akka's fault tolerance. As you move along, you'll explore a message-oriented event-driven application in Akka. You'll also tackle key issues like how to model immutable messages and domain models, and apply patterns like Event Sourcing, and CQRS. The book concludes with practical advice on how to tune and customize a system built with Akka.

    When boats break down, wreck or call for help, Seychelle and her tug Gorda are on the scene. Accidents do happen, but in South Florida, when somebody dies at sea, all too often it is murder. The Seychelle Collection Boxed Set Books #1-4 brings readers the opportunity to buy the entire Seychelle Sullivan series at one low price.Book #1 SURFACE TENSION On a steamy Florida morning Seychelle is answering a Mayday call launched from the five-million-dollar Broward yacht called Top Ten. Seychelle has a personal stake in this rescue: her former lover, Neal Garrett, is the yacht’s hired skipper. But being the first to reach Top Ten leads to a bloody payday. A beautiful woman has been stabbed to death onboard. And Garrett is nowhere to be found. T o find out what really happened to Neal Garrett, Seychelle must retrace his last steps, through two murders and a horrific crime wave, to a final confrontation with someone who may want to kill her . . . or be her salvation.Book #2 CROSS CURRENTFor Seychelle Sullivan, life is all about making a living, making love, and keeping her eye on the beauty that still remains in her beloved Florida. Then her life takes a turn when her tug intercepts with a swamped fishing boat in the Gulf Stream. Inside the boat are a murdered woman and a little girl in a white dress.Seychelle returns to shore with a traumatized Haitian girl named Solange. Determined to protect Solange, and somehow keep her from being sent back to Haiti, Seychelle becomes obsessed with the forces that nearly killed the girl. To get the answers she needs, Seychelle must return to where it all started: in the waters of the Gulf Stream, where people died for their dreams of freedom– and a man with a machete did the work of the devil himself.Book #3 BITTER ENDThe third book in the Seychelle Collection is loosely based on the real South Florida murder of Greek immigrant tycoon Gus Boolis, once the owner of South Florida's Sun Cruz Casino Gambling boats. Seychelle didn’t see the sniper who picked Nick Pontus off at the helm of his yacht, but she knows that there are plenty of people in South Florida who wanted to see the gambling-boat tycoon dead: the Russian mobsters looking for a piece of his casino action, the Indian gamers who resent his competition, and the ecological activists fighting his plans to develop Fort Lauderdale’s waterfront. But it’s Molly, Seychelle’s former childhood best friend and Nick’s ex-wife whom the cops zero in on. And despite her bitter feelings and against her better judgment, when her back-from-the-blue friend asks for help, Seychelle can’t just weigh anchor and cruise. She’s got to dive in.Book #4 WRECKERS’ KEYIn the 1800s, Key West was built by wrecking skippers who in feats of derring-do raced to shipping disasters to save valuable cargos from the ocean depths. Today, as too many boats chase too few wrecks, salvage has turned into a cutthroat corporate enterprise. And when a friend is killed, Seychelle begins to suspect a chilling scenario: that modern-day wreckers are causing yachts to crash onto the reefs–and killing off whoever gets in the way.Nestor Frias was piloting a billionaire’s luxury power yacht on its maiden voyage when it ran aground. A few days later, Frias was dead. His eight-months-pregnant widow is distraught, and a host of questions surround both Frias’s death and the ship’s accident. When another man dies while asking questions, Seychelle navigates the dangerous shoals and channels of the case and her life, unaware that a greater danger is looming: a murderous human storm designed perfectly for her.About the AuthorChristine Kling is the author of five nautical thrillers and one anthology of short stories.

    Changing the function of a word, or a room, can produce surprise and meaning. In How to Architect, Patt--an architect and the creator of a series of wildly popular online videos about architecture--presents the basics of architecture in A-Z form, starting with A is for Asymmetry (as seen in Chartres Cathedral and Frank Gehry), detouring through N is for Narrative, and ending with Z is for Zeal (a quality that successful architects tend to have, even in fiction--see The Fountainhead's architect-hero Howard Roark.)How to Architect is a book to guide you on the road to architecture. If you are just starting on that journey or thinking about becoming an architect, it is a place to begin. If you are already an architect and want to remind yourself of what drew you to the profession, it is a book of affirmation. And if you are just curious about what goes into the design and construction of buildings, this book tells you how architects think. Patt introduces each entry with a hand-drawn letter, and accompanies the text with illustrations that illuminate the concept discussed: a fallen Humpty Dumpty illustrates the perils of fragile egos; photographs of an X-Acto knife and other hand tools remind us of architecture's nondigital origins.How to Architect offers encouragement to aspiring architects but also mounts a defense of architecture as a profession--by calling out a defiant verb: architect!
