FastAPI is a young yet solid framework that takes advantage of newer Python features in a clean design. As its name implies, FastAPI is indeed fast, rivaling similar frameworks in languages such as Golang. With this practical book, developers familiar with Python will learn how FastAPI lets you accomplish more in less time with less code. Author Bill Lubanovic covers the nuts and bolts of FastAPI development with how-to guides on various topics such as forms, database access, graphics, maps, and more that will take you beyond the basics. This book also includes how-to guides that will get you up to speed on RESTful APIs, data validation, authorization, and performance. With its similarities to frameworks like Flask and Django, you'll find it easy to get started with FastAPI. Through the course of this book, you will: Learn how to build web applications with FastAPI Understand the differences between FastAPI, Starlette, and pydantic Learn two features that set FastAPI apart: asynchronous functions and data type checking and validation Examine new features of Python 3.8+, especially type annotations Understand the differences between sync and async Python Learn how to connect with external APIs and services

Easy to understand and fun to read, this updated edition of Introducing Python is ideal for beginning programmers as well as those new to the language. Author Bill Lubanovic takes you from the basics to more involved and varied topics, mixing tutorials with cookbook-style code recipes to explain concepts in Python 3. End-of-chapter exercises help you practice what you've learned. You'll gain a strong foundation in the language, including best practices for testing, debugging, code reuse, and other development tips.

If you're an experienced system administrator looking to acquire Linux skills, or a seasoned Linux user facing a new challenge, "Linux System Administration" offers practical knowledge for managing a complete range of Linux systems and servers. The book summarizes the steps you need to build everything from standalone SOHO hubs, web servers, and LAN servers to load-balanced clusters and servers consolidated through virtualization. Along the way, you'll learn about all of the tools you need to set up and maintain these working environments. Linux is now a standard corporate platform with users numbering in the hundreds of millions, and there is a definite shortage of talented administrators. "Linux System Administration" is ideal as an introduction to Linux for Unix veterans, MCSEs, and mainframe administrators, and as an advanced (and refresher) guide for existing Linux administrators who will want to jump into the middle of the book. Inside, you'll learn how to: set up a stand-alone Linux server; install, configure, maintain, and troubleshoot a DNS server using BIND; build an Internet server to manage sites, perform email and file transfers, and more; set up an email service for a small-to-medium-sized site, complete with authentication; install and configure Apache, PHP, and MySQL on a web server built from scratch; combine computers into a load-balanced Apache web server cluster based on the free Linux Virtual Server; set up local network services from distributed file systems to DHCP services, gateway services, print services, user management and more; use Linux virtualization with Xen or VMWare to run multiple kernels on one piece of hardware; manage each kernel's access to processor time, devices, and memory; create shell scripts and adapt them for your own needs; and back up and restore data with rsync, tar, cdrecord, Amanda, and MySQL tools. "Linux System Administration" is not only knowledgeable and practical, but convenient. The ingredients for this book had been scattered throughout mailing lists, forums, and discussion groups, as well as books, periodicals, and the experiences of colleagues. Everything is now in one handy guide. In the course of their research, the authors also solved many problems whose solutions were completely undocumented. They now pass their lessons on to you.
