题目链接 Problem Statement At Quora, we run all our unit tests across many machines in a test cluster on every code push. One day, we decided to see if we could optimize our test cluster for cost efficiency by using only one machine to run all N tests. S…

终于,你们期待的 flow.ci iOS 项目持续集成 开始公测了.在这几个工作日, flow.ci 做了些许「功能优化」与「问题修复」,性能和体验都在持续优化中.比如: iOS 快速入门文档更新: 构建列表状态显示优化,更方便地辨别当前任务的构建状态: 前端界面体验优化: GitLab 支持读取 Group 项目列表. 更新详情见 flow_ci changelog.如果你在使用过程中遇到问题,可以通过「在线消息」或去Gitter群 反馈给我们 :) 这期 CI Weekly 收录了一些国外公…

There are a total of n courses you have to take, labeled from 0 to n - 1. Some courses may have prerequisites, for example to take course 0 you have to first take course 1, which is expressed as a pair: [0,1] Given the total number of courses and a l…

我们都知道任务调度可以用Quartz,但对于简单的定时任务,可以直接用Spring内置的Schedule来实现.可以由两种方式,注释+XML配置 注解方式: 注解也要先在sping.xml配置文件中配置自动发现 XML中引入命名空间: xmlns:task="http://www.springframework.org/schema/task" http://www.springframework.org/schema/task http://www.springframework.o…

题目传送门:https://www.hackerrank.com/challenges/unique-colors 感谢hzq大神找来的这道题. 考虑点分治(毕竟是路经统计),对于每一个颜色,它的贡献是独立的.我们可以在一次点分治中合在一块处理(为什么时间复杂度是对的呢,因为我们每次改动只会根据当前点的颜色进行变动,而不是所有颜色对着它都来一遍).每次先对重心单独计算答案贡献,此时也将当前区域的各个答案贡献计算出来,并以此为基础(之后称之为基准贡献,即代码中的tot).对于每一棵子树,我们先df…

在spring 中的新引入的task 命名空间.可以部分取代 quartz 功能,配置和API更加简单,并且支持注解方式. 第一步: 在Spring的相关配置文件中(applicationContext.xml或者是{project_name}_servelt.xml或者是独立的配置文件如XXX_quartz.xml)中配置并开启Spring Schedule Task.注意其中高亮的部分是必须的. <?xml version="1.0" encoding="UTF-8…

现在做的项目都有用到Schedule,现在用一点时间来总结. 一.首先要到Nuget中下载Quartz.net. 二.下载下来了,你需要对它进行配置,使它能给你正常的使用. 三.在Global.asax中进行quartz进行初始化. 四.quartz_jobs_Schedule.xml 可以在这边个格式是这样的. <schedule> <name>DownloadDso</name> <job-type>LocalKwmsOne.Schedule.Jobs.…
