微软开发的 Visual Studio Code (简称 VS Code) 是一套非常热门的“编辑器”! VS Code 跨平台，且开放原始码。它虽然仅是一个轻量版的编辑器，却可经由安装延伸模组来支援程式码语法突显、侦错、自动补全、重构、Markdown...等琳瑯满目功能，打造你梦想中的 IDE (整合开发环境)。
VS Code 默认仅支援 JavaScript、TypeScript、CSS、HTML，同样能透过下载延伸模组来支援 Python、C/C++、Java、Perl、Go... 等其他程式语言。
据说 Perl 可能是近几年会消失的 5 种程式语言之一 (另外 4 个语言分别是 Ruby、Haskell、Object-C 跟 R)! 现在在 Visual Studio Code (简称 VS Code) 建立 Perl 的程式开发环境也算是帮 Perl 续一下命，大慈大悲、功德无量。
要建立好整个 Perl 的开发环境主要分为三个步骤:
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! 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!

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.
To address this issue please refer to the below knowledge base article
表示系统默认的 yum 套件库可能已经不存在!
我们可以在 vault.centos.org 找到可用的套件库来源:
1. xrdp 是放在 EPEL 套件库，所以我们要先安装 EPEL。依据不同版本的 CentOS 请参考: CentOS 如何加入第三方 Yum 套件库: EPEL。
2. 安装 xrdp 及 tigervnc server:
yum install xrdp tigervnc-server
3. 启动 xrdp
service xrdp start
4. 加到开机自动执行
chkconfig xrdp on
PS. 只要启动 xrdp 即可，tigervnc server 装好后就不用理它了。
设定与登入的方式与之前的教学一样，请自行参考。
