The Customer-Driven Culture: A Microsoft Story
If you're striving to make products and services that your customers will love, then you'll need a customer-driven organization. As companies transform their businesses to meet the demands of the digital age, they find themselves grappling with uniquely human challenges. Organizational knowledge becomes siloed, employees move to safeguard their expertise, and customer data creates polarization and infighting between teams. All of these challenges widen the distance between the people who make your products and the customers who use them. To meet today's challenges, companies need to do more than build processes for customer-driven products. They need to create a customer-driven culture. With the help of his friend and mentor Monty Hammontree, Travis Lowdermilk takes readers through the cultural transformation of the Developer Division at Microsoft. This book shows readers how to "hack" their culture and reduce the distance between them and their customers' needs. It's a uniquely ...

Using Asyncio in Python
If you're among the Python developers put off by asyncio's complexity, it's time to take another look. Asyncio is complicated because it aims to solve problems in concurrent network programming for both framework and end-user developers. The features you need to consider are a small subset of the whole asyncio API, but picking out the right features is the tricky part. That's where this practical book comes in. Veteran Python developer Caleb Hattingh helps you gain a basic understanding of asyncio's building blocks - enough to get started writing simple event-based programs. You'll learn why asyncio offers a safer alternative to preemptive multitasking (threading) and how this API provides a simple way to support thousands of simultaneous socket connections. Get a critical comparison of asyncio and threading for concurrent network programming; Take an asyncio walk-through, including a quickstart guide for hitting the ground looping with event-based programming; Learn the differen ...

Software Engineering at Google
Today, software engineers need to know not only how to program effectively but also how to develop proper engineering practices to make their codebase sustainable and healthy. This book emphasizes this difference between programming and software engineering. How can software engineers manage a living codebase that evolves and responds to changing requirements and demands over the length of its life? Based on their experience at Google, software engineers Titus Winters and Hyrum Wright, along with technical writer Tom Manshreck, present a candid and insightful look at how some of the world's leading practitioners construct and maintain software. This book covers Google's unique engineering culture, processes, and tools and how these aspects contribute to the effectiveness of an engineering organization. You'll explore three fundamental principles that software organizations should keep in mind when designing, architecting, writing, and maintaining code: How time affects the sustai ...
