序不知不觉一年又要过去了，又到了写总结的时候了。盘点整体而言，今年技术层面稍微有点拓宽，跨入了外表看上去高大上的流式计算领域，打开了另外一扇窗；而基于java的分布式/微服务领域，今年变化比较大，spring cloud netflix的部分组件宣布将要进入维护阶段，而国内spring cloud alibaba组件逐渐活跃起来，目前看来处于PublicEvolving阶段；而java自身也处在不断进化中，今年发布了java10及java11，明年java12也要来了，版本变化非常快。稍不留神就跟不上技术更迭了。今年不知道为什么没有什么想说的了，感觉整体而言自己表现非常一般，有点老气沉沉的感觉，可能是失去了年轻时候的激情，面对现实开始接受自己的平庸。展望面对纷繁复杂的技术，觉得技术真是无止境，有时候觉得自己真的很忙，时间真的不够用；但是面对生活，有时候又觉得人毕竟也是要生活的，是为技术而生活，还是为生活而技术，是一个值得思考的问题。今年定的几个目标基本也没有实现，明年就不再定具体的目标了，大的几个方向就是深入研究流式计算及系统架构，同时也希望自己脚踏实地的同时多仰望星空，多感受人文的世界。文章导航arch演进式架构聊聊系统设计中的trade-off聊聊rest
