Dive headfirst into solving actual enterprise problems and start cutting code from the word go. You will build complete applications around a variety of subjects using a range of different technologies and techniques, all of which are directly applicable to today's tech start-up world. Scale, performance, and high availability lie at the heart of the projects, and the lessons learned throughout this book will arm you with everything you need to build world-class solutions. Well-designed applications and sensible architectures can scale horizontally to cope with the demands of up to millions of users, while avoiding the prohibitive up-front investment that can bring a project to its knees. Mat Ryer has a family legend (or conspiracy) that tells of him programming computers from the age of 6—he and his father would build games and programs, first BASIC on a ZX Spectrum then later AmigaBASIC and AMOS on their Commodore Amiga. Many hours were spent manually copying out code from the Amiga Format magazine, before spending more still tweaking variables or moving GOTO statements around to see what might happen.The same spirit of exploration and obsession with programming led Mat to start work for a local agency in Mansfield, England, when he was 18, where he started to build websites and services. After contracting around London for a few years, coding everything from C# and Objective-C to Ruby and JavaScript, Mat noticed a new systems language called Go that Google was pioneering. Because it addressed very pertinent and relevant modern technical challenges, Mat started using it to solve problems while the language was still in beta and he has used it ever since.
I have been wanting to learn golang for some time, did the excellent 'Go Tour', and decided to try this next. I liked the premise of this book -- every project is a full, meaningful, end to end example, including (some) tests, (some) UI, etc. I typed in every line of code, built it, found my typos, ran it, troubleshot it, etc and by the end of a few days, Go actually feels familiar to me. It was a great 'breadth first' introduction to what it's really like to work with the language, and has given me a lot of context for deeper dives. Next up is the Kernighan/Donovan "The Go Programming Language", and I'm sure I'll retain significantly more of it due to doing this first.
