Building a central Go modules repository: GoCenter’s back to the future. @jfrog @ankushchadha111 GopherCon 2019 Lightning Talk Ankush Chadha About me • Dev Manager, Community & Partner Engineering

Introduction 5 Introduction 6 1 Go Environment Configuration Welcome to the world of Go, let's start exploring! Go is a fast-compiled, garbage-collected, concurrent systems programming language environment variables after the installation has completed.( Everything that looks like this means it's commented by a translator: If you are using 64-bit Windows, you should install the 64-bit version of systems. Going all the way to the end by clicking "next", ~/go/bin will be added to your system's $PATH after you finish the installation. Now open the terminal and type go . You should see the same

kindly answered my countless boring questions on go-nuts group and the Go project issue tracker. Ian's answers helped me clear many of my ever confusions in using Go. I want to give thanks to the following picture used in the covers of the digital and paper versions of this book is copied from one of from Rob's slides . Renee is the author of the lovely gopher iconic mascots used in the picture. (The Go 101 garbage collection GC). The Go design team also maintains a second Go compiler, gccgo. Nowadays it's use is less popular than gc, but it always serves as a reference, and both compilers are in active development

终极目标也是为了保证软件开发维护的效率和质量。 模块化设计-复用原则 REP 发布等同原则 (Release/Reuse Equivalency Principle) 软件复用的最小粒度应等同于其发布的最小粒度。 CCP 共同闭包原则 (Common Closure Principle) 为了相同目的而同时修改的类，应该放在同一个模块中。 对大部分应用程序而言，可维护性的重要性远远大于可复 用性，由同一个原因引起的代码修改，最好在同一个模块 用性，由同一个原因引起的代码修改，最好在同一个模块 中，如果分散在多个模块中，那么开发、提交、部署的成 本都会上升。 CRP 共同复用原则 (Common Reuse Principle) 不要强迫一个模块依赖它不需要的东西。 模块复用原则竞争关系张力图 模块化设计-单仓包设计 痛点： • 实现相同功能逻辑的模块百花齐放，选择成本过高 • 项目依赖的模块过多，项目整体的稳定性会受到影响 • Controller和Model的职责边界模糊，对于开发人员写好代码的 要求会比较高 经典MVC模式 代码分层设计-三层架构模式 表示层 - UI 位于三层构架的最上层，与用户直接接触，主要是B/S中 的 WEB页面，也可以是API接口。 业务逻辑层 - BLL 对具体问题进行逻辑判断与执行操作。 数据访问层 - DAL 实现数据的增删改查等操作，并将操作结果反馈到业务逻辑层 BLL。

Don’t pay for what you don’t use Java, Ruby, Smalltalk Everything is an object What are a Gopher’s values? The Zen of PythonGo Beautiful is better than ugly. Explicit is better than implicit. Simple implementation is hard to explain, it's a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea -- let's do more of those! –Tim Peters, PEP-20 PEP-20 “Namespaces are one honking great idea–let’s do more of those!” Each package should have a single purpose –Sandi Metz “Design is the art of arranging code to work today, and be changeable
