go programming book

The Tiobe programming language community released the July 2017 rankings, and the rankings were less than June, and Java, C, C + + and Python remained stable in the top 4. The go language soared this year, finally entered the top 10 this month, but only 55 in the same period in 2016, the speed is strong enough, the reason may be related to the development trend of large data ai. Last month, Google announce

If the Goroutine and channel are the cornerstone of the concurrency model that supports the go language, making the go language an extremely beautiful landscape in today's clustered and multicore era, the interface is the cornersto

Frankly speaking, I study Go time is not long, accumulation is not deep, this coincidence, the same group of colleagues was Shanghai University, one of the open source community, and we also hold some propaganda company and technology to share the intention, further, but also to learn to do a summary, so developed this share. In addition, most of the classmates are sophomore Junior "Meng New", considering the audience level and the nature of technolog

Original: Go programming tips--goroutine's elegant control GoroutineIs the most important mechanism of the go language, which Goroutine abstracts the complex asynchronous IO calls into synchronous calls, conforms to the normal sequence of human thinking, greatly simplifies the diffi

A switch statement allows a variable to be tested equal to the list of opposing values. Each value is referred to as a case, and the variable is switched on to check each switch case. In go programming, there are two types of switch. Expression switch-the value of the switch expression when the expression Switch,case contains a comparison. Type switch-in this type of switch, there is a type that contains

I saw an article in csdn a few days ago. Although I wrote my life experiences, the technology mentioned in it made me stunned (I couldn't speak for a long time ), (High School Students Write Nimda virus source code analysis, Tsinghua graduate students write the Linux server cluster system, lion is a four-year middle school student .....), hi, think about this. Let's take a look at yourself. It's really sad to think about how much we can't do in this regard. I calmed down and summarized some expe
