JDK14初体验

JDK14也发布挺长时间了，从使用JDK8来，一直就没有动过升级JDK的想法，想想这种也不符合自己的风格，所以这次正好拿自己平时弄的一个项目试试手。 Test blocks 其实就是文本块，在之前用Golang、python的时候都使用过，这次总算可以在Java中也同样的使用了。 image.png 相对之前需要使用+拼接确实能省去一些输入量。 Pattern Matching for the instanceof Operator image.png 使用instanceof做match操作时，如果match上就可以把t传成match上的class，同时使用一个引用指向match上的对象。 Switch Expressions image.png 在switch中可以使用新的语法case ...阅读全文

Python协程与Go协程的区别二

Go入门系列（一）伊始

欢迎来到Golang入门系列，说起这个系列出现的缘由，1、Golang的潜力无疑；2、笔者希望把所有有价值的主流语言全学一遍。 首先，我们来明确下定位，Go始于07年，在09年开源，官方团队来自Google。 然后是最耐人寻味的一点，它是一门面向对象的or面向过程的语言？ Yes and no. Although Go has types and methods and allows an object-oriented style of programming, there is no type hierarchy. The concept of “interface” in Go provides a different approach that we believe is easy ...阅读全文

利用阿里云容器服务实现自定义节点伸缩

摘要： 容器服务目前提供创建节点触发器的功能，调用节点触发器，并可以利用openAPI查看扩容出来的ECS节点方便管理和自动化的需求. 本文将向您介绍完成这一能力的步骤。 简介 阿里云容器服务很早就提供了基于集群CPU/内存的平均使用量触发节点自动伸缩功能，帮助许多客户自如应对业务压力的弹性变化。其原理是利用阿里云的云监控能力，在资源使用（cpu和memory）达到阈值时，触发节点伸缩。 同时还有一些企业级用户希望根据自身的监控数据和逻辑判断是否进行扩容和缩容操作，甚至可以按照固定时间进行节点扩容和缩容，针对这种场景，就需要调用的是扩容或者缩容触发器。 容器服务目前提供创建节点触发器的功能，调用节点触发器，并可以利用openAPI查看扩容出来的ECS节点方便管理和自动化的...阅读全文

构建更小Docker镜像的一些建议

背景: 前两天在群里看到有人提到说，自己构建了一个镜像，明明就只往base镜像中增加了tomcat，但是构建好的镜像大小最终却是两倍的tomcat包的大小，最后看到Dockerfile后才发现作者在把tomcat包拷贝进去之后，又使用RUN指令，执行了一次chmod a+x tomcat，我想说，这么搞镜像不大那是不可能的。另外一件事就是前段时间，同事说让搞一个公司级别的base镜像，要稳定并且尽量小，借着这两个事，和大家分享几点Docker镜像相关的事情。 首先，镜像的大小最终取决于如下几点: 1.业务需求和debug的便利性(比如科学计算和普通的java或者golang程序) 2.业务镜像构建的依赖特性(构建过程和交付物的依赖关系) 3.交付物的定义过程(Dockerfile分层过程中的...阅读全文
