Book excerpt: When her grandmother dies and the once-majestic family estate is sold, eleven-year-old Julia Lancaster and her aunt Constance must take to the road to find Julia’s long-lost mother. They bring with them only the most practical travel things—silver candlestick holders, a few Oriental carpets, some steamer trunks, and Julia’s beloved Brownie camera, which she will use to document their journey across 1960s America. On the road, Julia and her aunt meet a cast of peculiar characters, including guitar-strumming hippies in Greenwich Village, a legendary voodoo queen in New Orleans, the honorable proprietor of the World’s End Cattle Ranch in Texas, and the colorful sheriff of Gold Point, Nevada (population: 1), who also happens to be the town’s mayor, fire chief, and reverend. But will they find Julia’s mother and a place to call home? Poignant, engaging, and funny, Lesley M. M. Blume’s new novel is a meditation on the thin line between being an insider and being an outsider, and the deep-rooted need we all have to find a place where we can feel at home.

Book excerpt: The first months and years of motherhood can be the most challenging and disorienting of your life—and faith. When you’re surrounded by the happy chaos of children, how do you spend quiet time with God if the only quiet time you get is while you sleep? How can you demonstrate a solid spiritual life to your children if you don’t have time to pursue one yourself? When Julia Roller discovered that her spiritual growth had been stunted by the busyness of life with her toddler, she embarked on a yearlong journey through ten spiritual disciplines: prayer, fellowship, submission, study, simplicity, silence, worship, fasting, service, and celebration. As she focused on each discipline, she discovered practical ways to observe them—even in the chaos of her every day. Mom Seeks God offers a highly relatable story and useful advice to help new moms grow in their faith as they address life changes with grace, patience, and prayer. As readers discover ten essential faith practices, they’ll learn that motherhood, itself, is a spiritual discipline, and may be God’s most effective technique for forming a more Christ-like life.

Available in PDF, EPUB and Kindle. Book excerpt: Last Updated: December 2020 Based on Julia v1.3+ and JuMP v0.21+ The main motivation of writing this book was to help the author himself. He is a professor in the field of operations research, and his daily activities involve building models of mathematical optimization, developing algorithms for solving the problems, implementing those algorithms using computer programming languages, experimenting with data, etc. Three languages are involved: human language, mathematical language, and computer language. His team of students need to go over three different languages, which requires "translation" among the three languages. As this book was written to teach his research group how to translate, this book will also be useful for anyone who needs to learn how to translate in a similar situation. The Julia Language is as fast as C, as convenient as MATLAB, and as general as Python with a flexible algebraic modeling language for mathematical optimization problems. With the great support from Julia developers, especially the developers of the JuMP—Julia for Mathematical Programming—package, Julia makes a perfect tool for students and professionals in operations research and related areas such as industrial engineering, management science, transportation engineering, economics, and regional science.

Available in PDF, EPUB and Kindle. Book excerpt: "This book is a great way to both start learning data science through the promising Julia language and to become an efficient data scientist."- Professor Charles Bouveyron, INRIA Chair in Data Science, Université Côte d’Azur, Nice, France Julia, an open-source programming language, was created to be as easy to use as languages such as R and Python while also as fast as C and Fortran. An accessible, intuitive, and highly efficient base language with speed that exceeds R and Python, makes Julia a formidable language for data science. Using well known data science methods that will motivate the reader, Data Science with Julia will get readers up to speed on key features of the Julia language and illustrate its facilities for data science and machine learning work. Features: Covers the core components of Julia as well as packages relevant to the input, manipulation and representation of data. Discusses several important topics in data science including supervised and unsupervised learning. Reviews data visualization using the Gadfly package, which was designed to emulate the very popular ggplot2 package in R. Readers will learn how to make many common plots and how to visualize model results. Presents how to optimize Julia code for performance. Will be an ideal source for people who already know R and want to learn how to use Julia (though no previous knowledge of R or any other programming language is required). The advantages of Julia for data science cannot be understated. Besides speed and ease of use, there are already over 1,900 packages available and Julia can interface (either directly or through packages) with libraries written in R, Python, Matlab, C, C++ or Fortran. The book is for senior undergraduates, beginning graduate students, or practicing data scientists who want to learn how to use Julia for data science. "This book is a great way to both start learning data science through the promising Julia language and to become an efficient data scientist."
