This resource is essential for programmers eager to learn Go, presenting clear and idiomatic approaches to solving real-world problems. It is designed for readers without prior knowledge of Go or any specific programming language, making it accessible for those familiar with JavaScript, Ruby, Python, Java, or C++. The initial chapter serves as a tutorial on fundamental Go concepts through practical examples, including file I/O, text processing, simple graphics, and web clients and servers. Subsequent chapters delve into the structural elements of Go programs, covering syntax, control flow, data types, and program organization into packages, files, and functions, while illustrating the use of standard library packages and creating new ones. Later sections provide a detailed explanation of the package mechanism and project management using the go tool. The book introduces Go's unique take on object-oriented programming through methods and interfaces, emphasizing encapsulation, composition, and substitutability with realistic examples. Two chapters focus on concurrency, covering goroutines, channels, and shared variables, laying a solid foundation for newcomers to the topic. The final chapters address lower-level features, including metaprogramming with reflection and using the unsafe package for special cases, alongside creating Go bindings for C libraries with cgo.

The riveting story of a nation at a crucial crossroadsFrom the start of his stint as RTÉ's Washington Correspondent Brian O'Donovan's lively and authoritative reporting of a tumultuous period in American life has been must-watch TV.Four Years in the Cauldron is his account of four busy years working in the US. He draws a compelling picture, full of telling colour and detail, of covering its fractured politics, particularly the extraordinary presidency of Donald Trump and the knife-edge election of Joe Biden. And he gives his unique perspective on big stories such as the Covid emergency, the Capitol riot, the murder of George Floyd and trial and conviction of his police killer.He also provides a visceral sense of what it's like living in a country shaped by guns, God, far-fetched conspiracy theories and the running sore of racism. Yet, drawing on his network of contacts, neighbours, friends and family connections outside the white-hot heat of Washington politics, he writes about the lives of ordinary American people with nuance and understanding.Four Years in the Cauldron is a must-read for getting to grips with the US at a moment of profound reckoning.

The only book-length account of the life of Wendell Scott, the one-time moonshine runner who broke the color barrier in stock-car racing in 1952 and, against all odds, competed for more than 20 years in a sport dominated by Southern whites. Hard Driving is the story of one man's determination to live the life he loved, and to compete at the highest level of his sport. When Wendell Scott became NASCAR's version of Jackie Robinson in the segregated 1950s, some speedways refused to let him race. Scott appealed directly to the sport's founder, NASCAR czar Bill France Sr., who promised that NASCAR would treat him without prejudice. For the next two decades, Scott chased a dream whose fulfillment depended on France backing up that promise. France reneged on his pledge, but Scott did receive inspiring support from white drivers who admired his skill and tenacity, such as NASCAR champions Ned Jarrett and Richard Petty.
