## Prototype your design! Robert Griesemer dotGo 2016, Paris ## Getting to good software design • Literature is full of design paradigms • Usually involves ○ Design docs Feedback from reviewers • Often a “dry” exercise ☐ No software is created until design is “completed” ## How can we tell if we have a good design? ## Elsewhere, design thinking requires prototyping Try stuff Reframe problems mutation Define appropriate methods on that type A Go implementation allows us to explore our design. ## Key missing feature: Nice notation ### The work-around, accessor methods for multi-dim. index

Design Patterns are reusable elements of design that may help aid in making software more maintainable, flexible, and extensible. The term 'design patterns' can be traced Four' book Design Patterns, in which common software design patterns were defined and categorized. In this talk, you will learn the fundamentals of the creational, structural, and behavior design patterns

《Go Web 编程》 因为自己对Web开发比较感兴趣，所以最近抽空在写一本开源的书籍《Go Web编程》《Build Web Application with Golang》。写这本书不表示我能力很强，而是我愿意分享，和大家一起分享Go写Web应用的一些东西。 - 对于从PHP/Python/Ruby转过来的同学了解Go怎么写Web应用开发的 对于从C/C++转过来的同学了解Web到底是怎么运行起来的 这样读者就可以把相应的Markdown文件编译成html文件，执行go build build.go，执行生成的文件，就会在底目录下生成相应的html文件 ## 交流 欢迎大家加入QQ群：259316004《Go Web编程》专用交流群 大家有问题还可以上德问上一起交流学习：http://www.dewen.org/topic/165 ## 致谢 首先要感谢Golang-China的QQ群102319854， - 2.6. interface - 2.7. 并发 - 2.8. 小结 3.
