    Intended for developers who are already familiar with the Apex language, and experienced Java and C# developers who are moving to Apex, this book starts where the Force.com documentation leaves off. Instead of trying to cover all of the features of the platform, Advanced Apex programming focuses entirely on the Apex language and core design patterns. You’ll learn how to truly think in Apex – to embrace limits and bulk patterns. You’ll see how to develop architectures for efficient and reliable trigger handling, and for asynchronous operations. You’ll discover that best practices differ radically depending on whether you are building software for a specific organization or for a managed package. And you’ll find approaches for incorporating testing and diagnostic code that can dramatically improve the reliability and deployment of Apex software, and reduce your lifecycle and support costs. Based on his experience both as a consultant and as architect of a major AppExchange package, Dan Appleman focuses on the real-world problems and issues that are faced by Apex developers every day, along with the obscure problems and surprises that can sneak up on you if you are unprepared.

      Just after Jean Baur adopted a rescue dog, Bella, she lost her job at sixty-five. She decided to enroll Bella in a certified therapy-dog class. This new work, visiting hospital patients with her therapy job, gave Jean hope and purpose.   As Bella’s work expanded to nursing homes and elementary schools, the journey into the world of therapy-dog work allowed Jean and Bella to help others. They met an Alzheimer’s patient who learned to smile again after Bella took a treat from her hand. They befriended a six-year-old boy with autism who previously had a deep fear of dogs. Bella also coaxed an uncommunicative hospital patient to open up again after she jumped into bed with him.   National award-winning author Kim Kavin says Joy Unleashed “isn’t just another book about a dog and a person rescuing one another. It’s about how, together, Jean and Bella share their beautiful gift with countless other people who so desperately need to smile.”

    In The Book on Making Money, he reveals what he learned while successfully hitting this goal for seven years in a row, growing his annual income to more than $1 million. Walking readers through the steps he took to reach his goal, Oliverez shows how they can apply the same techniques to greatly increase their own income, whether they work for someone else or run their own business. Oliverez spells out his disagreements with the traditional wisdom that tells young adults to go to school, get good grades and find a safe, steady job - advice that has left many Americans with tens or hundreds of thousands of dollars in student loans, credit card debt or mortgages on homes they can't afford. He also assaults the idea of saving one’s way to wealth as absurd and counterproductive, using his own experience of trying to save money while poor as an example. Instead of promoting an austere lifestyle of clipping coupons and spending as little as possible, he shows how those habits can actually prevent people from becoming wealthy. Perhaps your goal is to create passive income, launch a startup or make money investing in the stock market. Maybe you're still an employee and you want to learn how to write a better resume, ask for a raise, and budget so you can get out of debt. This straight-forward guide will teach you how money works and give you the tools to achieve financial freedom.
