    With this guide, pioneering Go programmer Mark Summerfield shows how to write code that takes full advantage of Go's breakthrough features and idioms. Both a tutorial and a language reference, "Programming in Go" brings together all the knowledge you need to evaluate Go, think in Go, and write high-performance software with Go. Summerfield presents multiple idiom comparisons showing exactly how Go improves upon older languages, calling special attention to Go's key innovations. Along the way, he explains everything from the absolute basics through Go's lock-free channel-based concurrency and its flexible and unusual duck-typing type-safe approach to object-orientation. Throughout, Summerfield's approach is thoroughly practical. Each chapter offers multiple live code examples designed to encourage experimentation and help you quickly develop mastery. Wherever possible, complete programs and packages are presented to provide realistic use cases, as well as exercises. Coverage includes:-- Quickly getting and installing Go, and building and running Go programs -- Exploring Go's syntax, features, and extensive standard library -- Programming Boolean values, expressions, and numeric types -- Creating, comparing, indexing, slicing, and formatting strings -- Understanding Go's highly efficient built-in collection types: slices and maps -- Using Go as a procedural programming language -- Discovering Go's unusual and flexible approach to object orientation -- Mastering Go's unique, simple, and natural approach to fine-grained concurrency -- Reading and writing binary, text, JSON, and XML files -- Importing and using standard library packages, custom packages, and third-party packages -- Creating, documenting, unit testing, and benchmarking custom packages

    A dirty little secret assembly language programmers rarely admit to, however, is that what you really need to learn is machine organization, not assembly language programming. Write Great Code Vol I, the first in a series from assembly language expert Randall Hyde, dives right into machine organization without the extra overhead of learning assembly language programming at the same time. And since Write Great Code Vol I concentrates on the machine organization, not assembly language, the reader will learn in greater depth those subjects that are language-independent and of concern to a high level language programmer. Write Great Code Vol I will help programmers make wiser choices with respect to programming statements and data types when writing software, no matter which language they use.

    Your colorful pictures of flowers will produce a stunning flower art book that you can be proud of.In recent years coloring for grown-ups has become a widespread and growing hobby. There are of course many reasons for this, but here are just some... Coloring Lowers Stress And Anxiety Psychiatrists have long known that coloring relaxes the fear center of the brain and allows your mind to get some rest. In fact the founder of analytical psychology, Carl Jung, is known to have given his patients mandalas to color more than one hundred years ago. In today's hectic world the stress reducing properties of coloring are possibly more valuable than ever. Coloring Trains Your Brain To Focus Remaining inside the lines as you color needs focus and, while you are concentrating on this stress-free and relaxing activity, you can forget about your worries. Coloring is a mind exercise which allows you to put aside everything else for the time you spend coloring, and this is very important in our increasingly demanding world. Coloring Helps In The Development Of Fine Motor Skills And Vision Coloring forces the two hemispheres of the brain to work together and involves both the use of logic (necessary for coloring forms) and creativity (as we mix and match colors). In turn, this brings those areas of the brain responsible for fine motor skills and vision into play, and helps in keeping these active and in developing them further. It is this aspect of coloring which is being seen more and more as especially valuable for older individuals, as many in the medical profession believe that it can delay, or even prevent, the onset of dementia. Coloring Provides The Chance To Be Social Although you might feel that coloring should be a solo occupation, its rising popularity is quickly turning it into a social one. Friends, families, work colleagues and others are getting together to eat, drink and enjoy the chance to socialize, through their shared interest in coloring books. Without doubt, this is a perfect excuse for getting together, as coloring needs only a minimum of concentration and can easily be done in a group setting. Coloring Lets You Be Yourself There are no rules when it comes to coloring and your coloring book is your coloring book. If you mistakenly make the cat's back leg green because you mistook it for part of the grass, who cares? If you feel like making the sky yellow, what does it matter? You can be as creative as you wish because this is your coloring book, and yours alone."You may already be a convert to adult coloring, in which case you will already know and appreciate its value. This may however be a new project for you and one which you are considering for any one of several different reasons. If this is something new for you then I urge you to give it a try. There is a reason why so many people are fired up about the world of adult coloring, so join in and start enjoying the benefits for yourself today.
