Lincoln’s Dreams

From Publishers Weekly

As a researcher for a popular historical novelist, Jeff Johnston finds himself immersed in the minutiae of the Civil War, tracking down the name of a general’s favorite horse or the spot where Lincoln’s son was buried. His meeting with Annie, the patient of old friend Dr. Richard Madison, changes his perspective. While the novelist contemplates a book on Lincoln’s prophetic dreams and consults sleep specialist Madison, Jeff discovers that Annie is having vivid, horrible dreams of the Civil War containing details she couldn’t possibly know. The point of view is unmistakably that of defeated Confederate leader Robert E. Lee. Jeff tries to shield Annie from the opportunistic reach of both novelist and doctor, but he can’t protect her from herself, for she feels duty bound to refight the war if it will finally allow Lee some measure of peace. This charming, unpredictable book, with its unforced subtext of more recent wars and their veterans’ lingering bad dreams, is an impressive first novel from a talented writer whose short stories have already won acclaim.

The Lesson of Her Death

Bill Corde looks down at the face of the murdered girl and sees the horror of sudden death. He cannot know, as he stands there at the trampled, muddy scene beside the college girl’s corpse, that his own life is about to slip into terror. He cannot know that everything he holds precious is about to shatter before his eyes. He cannot know that his career–and his family–are about to enter a new dimension of danger. For Bill Corde, the killer is everything he fears most. For Sarah, Bill’s wild, learning-impaired daughter, trapped in a world of frustration and ridicule, he may be just the person she’s been waiting for. Someone who understands her worries and loneliness. Someone who signs his notes “The Sunshine Man.” Someone she can run away with–even a perfect stranger.

Leashed 4: Tangled Leashes

Sometimes we get what we never wanted, and Meg never wanted to be grand dame. Now that she’s got the job, she’s doing her damnedest to do it right. But it’s far from a one-woman show.Michael is the one who really should be running the show, but his newly discovered magic powers make managing his own life almost too much to handle. Then there’s Rudy. Sweet Rudy who is all about doing everything he can, but who’s just too young and inexperienced to be much help. So what’s a busy grand dame to do?Lucky for Meg, she’s got one more shape-shifter to lean on. Connections, personality, and background make Logan uniquely suited to be Meg’s righthand man, at least in the public eye. Problem is, he claims to be in love with her.

Learning Data Mining With Python

The next step in the information age is to gain insights from the deluge of data coming our way. Data mining provides a way of finding this insight, and Python is one of the most popular languages for data mining, providing both power and flexibility in analysis.
This book teaches you to design and develop data mining applications using a variety of datasets, starting with basic classification and affinity analysis. Next, we move on to more complex data types including text, images, and graphs. In every chapter, we create models that solve real-world problems.
There is a rich and varied set of libraries available in Python for data mining. This book covers a large number, including the IPython Notebook, pandas, scikit-learn and NLTK.
Each chapter of this book introduces you to new algorithms and techniques. By the end of the book, you will gain a large insight into using Python for data mining, with a good knowledge and understanding of the algorithms and implementations.

Learning Concurrency in Kotlin

**Take advantage of Kotlin’s concurrency primitives to write efficient multithreaded applications**
#### Key Features
* Learn Kotlin’s unique approach to multithreading
* Work through practical examples that will help you write concurrent non-blocking code
* Improve the overall execution speed in multiprocessor and multicore systems

#### Book Description
The primary requirements of modern-day applications are scalability, speed, and making the most use of hardware. Kotlin meets these requirements with its immense support for concurrency. Many concurrent primitives of Kotlin, such as channels and suspending functions, are designed to be non-blocking and efficient. This allows for new approaches to concurrency and creates unique challenges for the design and implementation of concurrent code. Learning Concurrency in Kotlin addresses those challenges with real-life examples and exercises that take advantage of Kotlin’s primitives. Beginning with an introduction to Kotlin’s coroutines, you will learn how to write concurrent code and understand the fundamental concepts needed to be able to write multithreaded software in Kotlin. You’ll explore how to communicate between and synchronize your threads and coroutines to write asynchronous applications that are collaborative. You’ll also learn how to handle errors and exceptions, as well as how to leverage multi-core processing. In addition to this, you’ll delve into how coroutines work internally, allowing you to see the bigger picture. Throughout the book you’ll build an Android application – an RSS reader – designed and implemented according to the different topics covered in the book
#### What you will learn
* Understand Kotlin’s approach to concurrency
* Implement sequential and asynchronous suspending functions
* Create suspending data sources that are resumed on demand
* Explore the best practices for error handling
* Use channels to communicate between coroutines
* Uncover how coroutines work under the hood

#### Who this book is for
If you’re a Kotlin or Android developer interested in learning how to program concurrently to enhance the performance of your applications, this is the book for you.
