这3周为了学习工作上需要的通讯和网络知识，看了大量电子网络文档，写了30篇笔记（都在掘金我的博客），并使用设备和笔记做了多次重复的验证。我认为这种方法对我快速获取知识有用。
做法就是把信息做一次粗加工，变成我容易接受的样子，具体而言：
长文划短。文章长了也是一个负担，因此有必要去掉重复和过分的多角度，那些角度是多余的，是个人上下文而定，因此笔记就是信息个人话的过程。具体而言，把长段落变成短段落，把并列内容提取出来单列，还有去掉不影响阅读的已知知识点。对于阅读英语不是母语的，长文化短价值更大。
直接点题。直接到位，避免或者减少反着说。我个人特别反感可以直说的，非要绕着说反着说，但是又大量的作者喜欢这样。他改不了，他提供的内容又是有价值的，怎么办？我改就是。我改了，我看着就心情好了。
清理重复。不同的作者，有不同的风格。有些人写的内容，直接到位，短小精悍，那么世界是宁静而美好的，也就是大家喜欢说的，都是干货。有的则是喜欢多角度的重复讲一个内容，有些人讲的内容是系统的，但是对我而言是已知的，那么重复看这些也是一个负担。
作为个人，难免有错误的呈现。比如简单的拼写，断句的错误，语法的啰嗦等。把它们修正，也是笔记的一重要构成。不然的话，那些看起来不大的错误，在重复验证的过程中，多看了几眼也是烦的，影响心情也就影响效果。
NOTE: 常常也需要把HTML Table转成Markdown语法，那么首先得把Table的源代码拷贝出来，做法就是：
打开Chrome DevTools
选中表
点击右键，点击copy，点击Copy Element
可以使用此工具，把剪贴板内容贴到Enter HTML table code内：

具体做法，举一个案例，如下。
加工结果
RADIUS authentication and accounting gives the ISP or network administrator ability to manage PPP user access and accounting from one server throughout a large network.
The MikroTik RouterOS has a RADIUS client which can authenticate for
- HotSpot,
- PPP,
- PPPoE,
- PPTP,
- L2TP and
- ISDN connections.
The attributes received from RADIUS server override the ones set in the default profile.
The RADIUS server database is consulted only if no matching user access record is found in router's local database.
If RADIUS accounting is enabled, accounting information is also sent to the RADIUS server default for that service ,else Traffic is accounted locally with MikroTik Traffic Flow and Cisco IP pairs and snapshot image can be gathered using Syslog utilities.
笔记过程
完全清晰的直接删除，比如括号内的（RADIUS, short for Remote Authentication Dial-In User Service, is a remote server that provides authentication and accounting facilities to various network apliances）. RADIUS authentication and accounting gives the ISP or network administrator ability to manage PPP user access and accounting from one server throughout a large network. 长段落分段。The MikroTik RouterOS has a RADIUS client which can authenticate for 并列的关键知识应从长句中提出来（HotSpot, PPP, PPPoE, PPTP, L2TP and ISDN connections. （前后两句是一个含义的反向重复，删除后一句）The attributes received from RADIUS server override the ones set in the default profile, but if some parameters are not received they are taken from the respective default profile.
The RADIUS server database is consulted only if no matching user acces(拼写错误) record is found in router's local database.
这两句的后一句是直言，前一句是反向说，但是也提供了后一句没有的信息，因此把直言放到前面。Traffic is accounted locally with MikroTik Traffic Flow and Cisco IP pairs and snapshot image can be gathered using Syslog utilities. If RADIUS accounting is enabled, accounting information is also sent to the RADIUS server default for that service.
