Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.

    Johnstone, Best-selling western author, John Spiars has created a timeless hero of the old west. The first novel in the Heck Carson Series, Riders of the Lone Star brings the wild and lawless Texas frontier to life. When the Law ain’t enough… He brings Justice. The year is 1852. Settlers on the Texas frontier are at the mercy of hostile Comanche and vicious outlaws, and the only ones holding the line between life and death are a few brave men, known as Texas Rangers. Outnumbered and outgunned, they bring law and order to the untamed land. They face impossible odds with nothing more than grit, determination, and a fast gun. It is this adventure and excitement that lures sixteen-year-old Jesse “Heck” Carson to leave his families ranch to join the fight. Heck quickly learns that this life comes at a price, the cost of which is hardship, danger, and possibly his own life. The bonds of friendship, loyalty, and duty lead him into epic battles that test his courage and resolve, and along the way he learns what it means to wear the star of the Texas Rangers. Excerpts: As fast as he could, he pulled the hammer back and fired, the first Comanche jerked once and hit the ground. The other warrior was no more than two feet away now. Heck wondered if he had another bullet left. Had he fired five or six shots? He couldn’t remember. Saying a silent prayer, Heck pulled the hammer back and looked at his approaching enemy. The point of the warrior’s lance was inches away from his chest when heck pulled the trigger. The barrel of the Walker was almost touching the chest of the charging Indian. Heck heard no sound, but saw the smoke pour out of the barrel and the big warrior dropped to his knees, and fell on top of the young Ranger. Lieutenant Sutter and Corporal Anderson approached the men on horseback, ready to do what had to be done. Looking at the group of riders, however, Sutter immediately recognized he had made a terrible mistake. These men were not military, not even by Southern standards. They were unkempt, filthy, and armed to the teeth. His heart sank as he noticed that most of the detachment were Mexican and their guns were not in their holsters. “What is going on here?” he said, unable to believe what he was seeing. The lead rider smiled and said, “This was even easier than Senor Cortina said it would be. Thank you.” Without saying another word, the man raised his pistol and fired two quick shots, hitting both Lieutenant Sutter and Corporal Anderson between the eyes. The man wheeled around with his rifle as Heck landed on his back, but it was a fruitless gesture. There was a look of pained surprise on the man’s face as Heck covered his mouth and pulled him to the floor. Heck plunged his knife into the man’s chest several times, as he kept his hand over the man’s mouth. After several seconds his muffled cries were silent. John Spiars is the author of the Heck Carson Series. He is a writer and amateur historian with a passion for the history and myths of the "Old West". His hope is to keep alive the western genre for this generation and all of those to come, while both entertaining and educating readers of all ages. He is a native Texan and lives in North Texas with his wife and four children. When not writing western novels, he maintains a blog and Facebook page about Texas history and travel entitled Under the Lone Star.

    Mike and his cousin, Salvatore “Sally-Boy” Boccanera are born one minute apart, in the same hospital, and it seems like they’ll never be more than a minute apart the rest of their lives. Their experiences knocking around the city are challenging, funny, touching, and at times disturbing—all of the ingredients that define growing up. Life lessons happen in the Italian bakery Sally-Boy’s father owns, where the boys loll and play, with ears and eyes wide open. But maybe the biggest lesson of all looms over Mike’s father, who’s determined to make drastic changes in pursuit of a better life. Hanging in the balance, at the center of the boys’ tumultuous lives, is the fire escape. It’s a place that is uniquely theirs, and Mike best describes its spell, recalling how it reeks in the rain, blisters in the sun, and ices over in the snow. It’s where he and Sally-Boy talk and think and philosophize and plot and try to understand all they can about themselves and the world.
