工作上我会用到 Skype 与同事对话，Skype for Desktop 默认是单一视窗接口，一次只能与一个人聊天，而 Skype 有提供一个“分割检视 (Split View)”模式，让 Skype 可以同时开启多个视窗来跟不同人聊天:
因为能开启多个视窗，我时常会用来:
对我而言，Skype 能同时开启多个聊天视窗是很重要且实用的功能。

Transport Layer Security (TLS), the successor to Secure Socket Layer (SSL), is a network protocol that encrypt communications between TLS servers (e.g., websites) and TLS clients (e.g., web browsers). Every communication is secured by a cipher suite: a combination of several algorithms working in concert. Cryptographic algorithms do not have a defined lifetime, but academics, researchers, and nation states are constantly evaluating them for weaknesses. Consensus on which algorithms are untrustworthy evolves over time, and if a communication is protected with a weak cipher suite then that communication can be altered or decrypted.
The SSH server is configured to support either Arcfour or Cipher Block Chaining (CBC) mode cipher algorithms. SSH can be configured to use Counter (CTR) mode encryption instead of CBC. The use of Arcfour algorithms should be disabled.
The SSH server is configured to support MD5 algorithm. The cryptographic strength depends upon the size of the key and algorithm that is used. A Modern MAC algorithms such as SHA1 or SHA2 should be used instead.

The site responds to HTTP requests without ultimately redirecting the browser to a secure version of the page. Since the site allows plaintext traffic, a man-in-the-middle attacker is able to read and modify any information passed between the site and the user. There are a variety of situations in which an attacker can intercept plaintext traffic in a man-in-the-middle position, including but not limited to:
It's important to remember that in many of the above situations, an attacker can not only read traffic, but also actively modify the traffic. Even if a site that does not contain sensitive information, an attacker can still inject malicious content to a user’s browser.
我的车机是 Pioneer AVH-Z9250BT，手机是小米 12，我通常是使用无线的方式连接车机的 Android Auto。
不过在车机上的 Android Auto 使用 Google Maps 导航时，偶尔会出现行车位置漂移、GPS 讯号中断、正在搜寻 GPS 讯号，或无法显示地图...之类的问题! Android Auto 的 GPS 定位应该是来自手机，但是同一时间，如果我开启手机上的导航王来查看，导航王的定位却又无比正确!
原本以为是我我的车机太烂，或有相容性的问题，上网寻找答案，又发现很多网友有同样的问题，其中也不乏一些百万名车内建的车机! 幸好有找到解决方法!

这些指令的执行档通常是放在 C:\Windows\System32\，可在这些地方执行指令:
我的电脑在某次更新 Windows 10 之后，原本已设定好不让它自动关机的电脑竟会进入休眠状态! 原因似乎是进入休眠的时间被改动了，而在 Windows 的设定中却不容易找到“休眠”的细部选项!
这 Windows 可真爱找麻烦!
先来看一下 Windows 10 关机选单的 4 个选项做为相关知识:
若执行 yum 出现:
http://mirror.centos.org/centos/6/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
