Recently encountered a scene: PHP project needs to use a third-party function (stuttering participle), and on GitHub there is a class library written in Golang. So the question is, how do you achieve communication between different languages? The general scenario: Write a http/tcp service with Golang, PHP communicates wi

If you are interested in Golang but have not yet begun to get started, this article is for you. Why do you learn Golang? Many of the articles lobbying developers to try Golang.For example, a speech by Golang's main designer, a German spat, a preface to a book by a domestic Golang preacher. I do not want to repeat Daniel's point of view, just to talk about their

Golang, which is the go language, has now been released to 1.4.1 version, the advantages of language features and Google behind the strong backers of what is not said. Golang's official offers a binary installation package on multiple platforms, unfortunately not a binary installation package that does not release the arm platform. The ARM platform is not able to download the binary installation package directly from the official website, fortunately

Some views on the design pattern of Golang For C, C + +, the object of design exist these several problems 1, the object is dead, only their own properties, behavior (function). There are no mechanisms that can be implemented independently 2, the object is alive, has its own attributes, behavior (functions), as well as independent execution of the activities (their own independent thread). However, due to system constraints, this number of objects

As a transport personnel, the use of Python language is sufficient, in theory, do not need to understand Golang.

Recently in tinkering with the implementation of the Golang daemon, I have no intention of discovering supervisor this interesting thing. Supervisor is a UNIX system process management software that can be used to manage Apache, Nginx and other services, if the service hangs can let them automatically restart. Of course, can also be used to implement the Golang daemon, the following describes the implementa

In the previous article, "Using Golang to design our Ubuntu scope," We've covered how to use Golang to develop Ubuntu scope. In today's article, let's take a brief look at how to use Golang to develop QML applications. This is a good choice for some of the familiar Golang languages, but not very familiar with C + + dev

Under the microservices architecture, we decompose the original single application into a series of independent, focused microservices based on functional boundaries. Each microservices corresponds to a component in a traditional application, but can be compiled, deployed, and scaled independently. Each team c

The ingenious combination of Docker and Golang "Editor's words" This is a simple repertoire of tips and tricks that show how to make Docker more useful when using the go language. For example, how to use different versions of the Go tool chain to compile go code, how to cross compile to a different platform (and test results!). Or how to make a really small container image.
