运筹帷幄之中，决胜千里之外 - 西汉·司马迁《史记·高祖本纪》 使用场景 之前一篇文章介绍了通过XML文件来自定义MTR的背景图片，其实我们通过XML文件其实还可以做更多在MTR会议室的日常运维任务。 想像一下这样一个场景：当你需要为分布在不同地方的多间MTR会议室进行配置或管理的时候，例如: 变更MTR会议室的帐号？ 在改密码之后需要更新MTR设备的密码？ 为了安全原因需要隐藏会议主题？ 会议室新购多一块会议交互大屏，变成了双屏会议室？我们需要打开MTR的双屏显示开关 自定义MTR的主题图片？参考这篇： 自定义主题让你的MTR会议与众不同 具体配置步骤 这些操作我们都可以通过XML配置文件的方式远程推送给MTR设备来实现（用共享目录的方式来推，用组策略来推，用SCCM来推，都行，只要你能够把SkypeSettings.XML这份XML文件放在MTR的指定目录即可） 什么是MTR? Microsoft Teams Room 首先需要先创建一份名字为SkypeSettings.XML的文件。 接着就可以去修改SkypeSettings.XML里面的内容,例如以下代码配置了三个设置（自动屏幕共享，隐藏会议主题，MTR帐号）。 PS. 当你要运维多个MTR会议室时，你不需要把所有参数都放在XML里面，只需要把要改的放进来即可，这样就可以有针对性地去维护这些会议室。

I am trying to develop a HTML5 white board. I want the users viewing the board to know where exactly the presenter is pointing within the screen. I am able to collect the mouse movements using this jquery function. But even if i succeed to pass this values to other clients using php, how can I emulate it? Is it possible to move a small pointer image, based on the co-ordinates obtained from the presenter? Is there any functions or snippets from which I cant get started? Will this be very hardware intensive task that normal people may have issue? Is this the best way to achieve what I am trying

I am occasionally called upon impromptu to white-board (non-virtually) data flows, architecture diagrams etc., for both a technical and non-technical audience. Unfortunately my drawing skills (and print legibility) are terrible. How can I become more effective at doing this? I am looking for tips on standard symbols and connectors to use, some standard ways of organizing and categorizing the information (e.g., swim lanes ), etc. What can I practice to become better at this? I want these visual presentations to be effective in communicating my ideas, and badly presented diagrams can make the
