12. The Biggest Safety Threat Facing Airlines 航空公司面临的最大安全威胁 (1) The biggest safety threat facing airlines today may not be a terrorist with a gun,but the man with the portable computer in business class。In the last 15 years,pilots have reported well over 100 incidents that could have been caused electromagnetic interference。The source of this interference remains unconfirmed,but increasingly,experts are pointing the blame at portable computers,radio and cassette players and mobile phones。 (2) RTCA,an organization which advises the aviation industry,has recommended that all airplanes ban such

PHP设计模式—装饰器模式

南楼画角 提交于 2020-05-05 18:35:44
定义: 装饰器模式(Decorator): 动态的给一个对象添加一些额外的职责,就增加功能来说,装饰器比生成子类更加灵活。 结构: Component: 定义一个对象接口,可以给这些对象动态地添加职责。 ConcreteComponent: 定义了一个具体的对象,也可以给这个对象添加一些职责。 Decorator: 装饰抽象类,继承了 Component ,从外类来扩展 Component 类的功能,但对于 Component 来说,是无需知道 Decorator 的存在的。 ConcreteDecorator: 具体的装饰对象,起到给 Component 添加职责的功能。 代码实例: 这里以一个游戏角色为例,角色本身自带基础攻击属性,也可以通过额外的武器装备增加属性值。这里的装备武器就是动态的给角色添加额外的职责。 1、角色Role.php,对应Component /* * * 角色,抽象类 * Class Role */ abstract class Role { /* * * @return mixed */ abstract public function getName(); /* * * @return mixed */ abstract public function getAggressivity(); } 2、武器Arms.php

在英语中,主要有三大从句,即 名词性从句 (包括 主语从句 , 宾语从句 , 表语从句 , 同位语从句 )、 形容词性从句 (即 定语从句 )、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。 引导 主语从句 连词有that,whether,who,what,whatever等 定义:如果一个句子在复合句中充当一个主语,那么这个句子就是 主语从句 . 第一部分:常规主语从句,即句子在复合句中充当一个主语 (1)That he finished writing the composition in such a short time surprised us all. (2)Whether we will go for an outing tomorrow remains unknown. (3)Who will be our monitor has't been decided yet. (4) Whom we must study for is a question of great importance.

SonarQube 解决了代码追踪问题

3 月,跳不动了?>>> 通过不断分析代码以了解潜在的质量问题,开源的 SonarQube 项目支持了 DevOps 的“尽早发布和经常发布” 的思维模式。 越来越多的组织正在实施 DevOps 以便在通过中间开发和测试环境以后更快更好的将新代码引入到生产环境。虽然版本控制、持续集成和部署以及自动化测试都属于 DevOps 的范畴,但仍然存在一个关键问题:组织如何量化代码质量,而不仅仅是部署的速度? SonarQube 是用来填补这个空隙的一种选择。它是一个开源平台,通过代码的自动化静态分析不断的检查代码质量。 SonarQube 支持 20 多种语言的分析,并在各种类型的项目中输出和存储问题。 SonarQube 同时也提供了一个可同时维护和管理不同项目、不同代码的集中的环境。可以为每个项目定制规则。持续的检查和分析代码的健康轨迹。 SonarQube 还可以集成到可持续集成和开发(CI/CD)流程中,协助和自动确定代码是否为生产环境做好了准备的过程。 它可以衡量什么 开箱即用,SonarQube 可以测量的关键指标,包括代码错误、代码异味code smells、安全漏洞和重复的代码。 代码错误 是代码中的一部分不正确或无法正常运行、可能会导致错误的结果,是指那些在代码发布到生产环境之前应该被修复的明显的错误。 代码异味 不同于代码错误,被检测到的代码是可能能正确执行并符合预期

问题 I just found out about gunDB and the concept seems very interesting and I'd like to find out more about it before starting to evaluate it further. If I wanted to build a chat app like the tutorial but implement chat rooms . Would there be a way for clients to only "subscribe" to certain chat rooms only, and avoid transferring the content of every other chat room? How does that affect persistence, if not all data is sync'd to all clients? Do we need to run a special client (ie a server?) that

Keeping a Gun DB user authenticated during a session

问题 I am trailing the Gun/SEA authentication system for a distributed/serverless application. This app is saving session information to local storage when a Gun user is authenticated. One problem I am having is when the page is refreshed or a new tab is opened I want to keep the user authenticated while the session is valid and I would rather not store the user name and password in local storage due to XSS and physical security reasons. Is there a solution to this problem currently? I think
