Building and deploying new applications is faster with containers.

Docker containers wrap up software and its dependencies into a standardized unit for software development that includes everything it needs to run: code, runtime, system tools and libraries.

This guarantees that your application will always run the same and makes collaboration as simple as sharing a container image.

One time I accidentally discovered Kali’s tool Lynis, I tried to run it and found a new continent. So I was out of control, and was installed Lynis on Linux systems such as Raspberry Pi, Notebook and VPS.
Then I summed up the security advice provided by Lynis and wrote this article.

Caddy, sometimes clarified as the Caddy web server, is an open source, HTTP/2-enabled web server written in Go. It uses the Go standard library for its HTTP functionality.

One of Caddy’s most notable features is enabling HTTPS by default.

Other web servers were designed for the Web, but Caddy was designed for humans.

自从Phicomm N1替代*Raspberry Pi 2b+*成为家里的媒体中心后，家里的幸福感提升了许多。直到近来发现它不支持手机屏幕镜像功能（声画同步传输），于是就有这篇文章。

因为国内网站需要备案，所以主机在香港或国外的站点无法备案，国内的 CDN 自然而然也就无法使用了。
好在国外的 Cloudflare 提供免费优质的 CDN，我们可以用它来加速网站访问速度。

如果想要自己建站，那么VPS, Domain, Web Server 一个都不能少。建站初期或建设临时网站，可以先申请免费域名来使用。如果网站准备长期使用，建议网站稳定后更换为付费域名。
毕竟付费域名的使用时效长且稳定性好，所以搜索引擎也倾向于优先收录付费域名。

WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the lighttpd server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

RaspberryPi 2b 在我家做了 2 年多的媒体中心，随着时间的推移，它百兆网口和 GPU（不支持硬解 H265) 的缺陷越来越明显了。终于在 PDD 寻了一台 Phicomm N1 （千光网口与硬解 H265），到手就刷了官改ROM，顺利替代了 RaspberryPi 并且提升了家庭的幸福指数。

想把家里2块老旧的80G硬盘当作下载盘来使用，但总不能每次下载时查看硬盘剩余空间够不够吧，想着如果可以把这2块硬盘当作一块160G的硬盘来使用就好了。在一番搜索后，发现 LVM 完全可以满足我的需求。

The layout of the home is strange, and the location of the router is relatively biased, so in some places, wifi cannot be covered. I want to add another WIFI router to achieve seamless roaming. This article is the knowledge point learned.
