工作上我會用到 Skype 與同事對話，Skype for Desktop 預設是單一視窗介面，一次只能與一個人聊天，而 Skype 有提供一個「分割檢視 (Split View)」模式，讓 Skype 可以同時開啟多個視窗來跟不同人聊天:
因為能開啟多個視窗，我時常會用來:
對我而言，Skype 能同時開啟多個聊天視窗是很重要且實用的功能。

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.
我的車機是 Pioneer AVH-Z9250BT，手機是小米 12，我通常是使用無線的方式連接車機的 Android Auto。
不過在車機上的 Android Auto 使用 Google Maps 導航時，偶爾會出現行車位置漂移、GPS 訊號中斷、正在搜尋 GPS 訊號，或無法顯示地圖...之類的問題! Android Auto 的 GPS 定位應該是來自手機，但是同一時間，如果我開啟手機上的導航王來查看，導航王的定位卻又無比正確!
原本以為是我我的車機太爛，或有相容性的問題，上網尋找答案，又發現很多網友有同樣的問題，其中也不乏一些百萬名車內建的車機! 幸好有找到解決方法!

這些指令的執行檔通常是放在 C:\Windows\System32\，可在這些地方執行指令:
我的電腦在某次更新 Windows 10 之後，原本已設定好不讓它自動關機的電腦竟會進入休眠狀態! 原因似乎是進入休眠的時間被改動了，而在 Windows 的設定中卻不容易找到「休眠」的細部選項!
這 Windows 可真愛找麻煩!
先來看一下 Windows 10 關機選單的 4 個選項做為相關知識:
若執行 yum 出現:
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.
