Run custom TextSecure (Signal) server

北慕城南 提交于 2019-11-30 12:10:22
问题 I am trying to start my custom TextSecure (Signal) server. I want to use it for all functions that Signal has (both SMS and telephony). I believe that I also need redphone server to run telephony. I've found github repos for TextSecure server only https://github.com/WhisperSystems/TextSecure-Server but no repos for redphone server. I think that I also need to run this server https://github.com/WhisperSystems/PushServer to properly operate Signal. I have tried downloading whole TextSecure

分布式设计与开发------几种必须了解的分布式算法

那年仲夏 提交于 2019-11-30 11:48:30
分布式设计与开发中有些疑难问题必须借助一些算法才能解决,比如分布式环境一致性问题,感觉以下分布式算法是必须了解的(随着学习深入有待添加): Paxos算法 一致性Hash算法 Paxos算法 1)问题描述 分布式中有这么一个疑难问题,客户端向一个分布式集群的服务端发出一系列更新数据的消息,由于分布式集群中的各个服务端节点是互为同步数据的,所以运行完客户端这系列消息指令后各服务端节点的数据应该是一致的,但由于网络或其他原因,各个服务端节点接收到消息的序列可能不一致,最后导致各节点的数据不一致。举一个实例来说明这个问题,下面是客户端与服务端的结构图: 当client1、client2、client3分别发出消息指令A、B、C时,Server1~4由于网络问题,接收到的消息序列就可能各不相同,这样就可能由于消息序列的不同导致Server1~4上的数据不一致。对于这么一个问题,在分布式环境中很难通过像单机里处理同步问题那么简单,而Paxos算法就是一种处理类似于以上数据不一致问题的方案。 2)算法本身 算法本身我就不进行完整的描述和推导,网上有大量的资料做了这个事情,但我学习以后感觉莱斯利·兰伯特(Leslie Lamport,paxos算法的奠基人,此人现在在微软研究院)的 Paxos Made Simple 是学习paxos最好的文档

Difference between a server with http.createServer and a server using express in node js

a 夏天 提交于 2019-11-30 11:18:35
What's the difference between creating a server using http module and creating a server using express framework in node js? Thanks. Ultimately, express uses node's http api behind the scenes. express framework The express framework provides an abstraction layer above the vanilla http module to make handling web traffic and APIs a little easier. There's also tons of middleware available for express (and express-like) frameworks to complete common tasks such as: CORS, XSRF, POST parsing, cookies etc. http api The http api is very simple and is used to to setup and manage incoming/outgoing ,HTTP

在Active Directory域中限制用户并发登录:LimitLogin VS UserLock

百般思念 提交于 2019-11-30 10:12:25
LimitLogin 是一款于2005年面世的登录管理工具,由一名微软合作伙伴技术专家和一名应用程序开发顾问合力开发。LimitLogin旨在在Active Directory域中跟踪和限制并发工作站和终端用户登录。 UserLock 是由微软合作伙伴 IS Decisions 提供的企业级软件解决方案,专门保护Windows和Active Directory基础架构,能够监控和审计用户对Active Directory网络的访问。UserLock可按一系列标准进行拒绝或限制访问,这些限制可以根据用户、用户组、企业部门或会话类型(工作站、终端、交换机、互联网信息服务、Wi-Fi/Radius或VPN/RAS等)来自定义。UserLock还可以实时监控所有会话,对可疑事件快速响应,提供警报和消息,并为审计和鉴证提供访问信息日志。 以下表格对LimitLogin和UserLock的特性做了详细对比: 特性 LimitLogin UserLock 代理技术 Logon Scripts Windows Service AD架构更改 - Web Server需求 - 工作站OS支持 Windows 2000 SP4, Windows XP SP1 Windows XP, Windows Vista,Windows 7, Windows 8 服务器OS支持 Windows Server

如何在 IIS 上搭建 mercurial server

冷暖自知 提交于 2019-11-30 09:12:27
mercurial server 对于代码管理工具,更多的人可能更熟悉 Git 一些(Git 太火了)。其实另外一款分布式代码管理工具也被广泛的使用,它就是 mercurial 。多人协作时,最好能够通过创建一个 mercurial server 对用户进行权限认证,同时也会方便持续集成。 关于创建 mercurial server 的步骤,mercurial 官方的 wiki 有说明,网上也有很多朋友分享了自己的创建过程。但笔者在创建的过程中还是颇费了一番周折才最终成功,所以也在此分享一下自己的经验,希望对朋友们有所帮助。 文章来源: 葡萄城产品技术社区 一、环境及软件安装 笔者使用的操作系统为 Server2012R2 x64 Standard 中文版。 首先,在安装其他工具前,需要先安装 IIS。安装 IIS 时需要注意,一定要把 CGI 和 ISAPI 这两个选项都勾选上。 然后,安装 Python,使用默认设置安装 python 2.7.x。 最后,安装 mercurial server,请从 这里 在这里下载 mercurial server 的安装包并安装,安装完成后检查 C:\Python27\Lib\site-packages\mercurial 目录是否被正确安装! 注意,python 和 sercurial server 必须保持相同的架构,不要一个安装

Load local data into IPython notebook server

烂漫一生 提交于 2019-11-30 07:34:12
I did setup an ipython server for other people (in my company department) to have a chance to learn and work with python. Now I wonder how people can load their own local data into the ipython notebook session on the remote server. Is there any way to do this? Since you have jupyter installed, all users should see the files/folders in the jupyter startup directory as well as its subdirectory. The new button on the jupyter notebook can be used to create a new file/folder or even a terminal. Files can be uploaded using drag-drop or click here feature highlighted below. volhv An alternative way

Generate Swagger Document for existing NodeJS server

问题 According to Swagger website, there are two approaches: Bottom-up and Top-down. I have an existing NodeJS server that I'd like to deploy in the Azure enviroment, that require a swagger document (API APP). Does anyone know a tool for generating the swagger using the code? Even better if you could point a tutorial. I couldn't find it. 回答1: It’s not difficult to integrate Swagger in exist express applications following this tutorial. Generally, we can follow these steps: Add the dependencies in
