macOS上基于httpd搭建WebDav服务

在局域网中，要想共享或访问 macOS 机器上的文件，可以通过文件共享、屏幕共享或 远程登录 这几种方式：

  1. FS（SMB）: Set up file sharing on Mac，Control access to your Public folder on Mac。
  2. SSH+SFTP: Allow a remote computer to access your Mac
  3. Screen Sharing（VNC）: Turn Mac screen sharing on or off，Share the screen of another Mac。
  4. RD: Enable remote management for Remote Desktop

FS 模式一般默认开放给 everyone 只读，可以以 Guest User 身份免登录访问，但是一旦涉及到要开放写权限，会涉及到系统账户分级分组管理和ACL权限控制和分配粒度问题。局域网内怎么样部署简易轻量的共享同步存储系统呢？

在多终端设备时代，很多人都购买了在线网络云盘服务，或者自己动手DIY搭建部署家庭局域网NAS私有云服务器，作为家里的数据和影音中心，方便文件共享和存储备份同步。另一个日益增长的需求就是分布式协作，Google文档、腾讯文档等产品就是解决这类问题的在线协同编辑的办公软件。

SDLC methodology

The abbreviation SDLC stands for Software Development Life Cycle. It is frequently used in technology to refer to the entire process of technology innovation and support.

In software engineering, a software development process or software development life cycle is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.

Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming.

Abstraction & Virtualization

In software engineering and computer science, abstraction is the process of generalizing concrete details, such as attributes, away from the study of objects and systems to focus attention on details of greater importance. Abstraction is a fundamental concept in computer science and software engineering, especially within the object-oriented programming paradigm.

In computing, virtualization (refer to IBM, AWS) is the act of creating a virtual (rather than actual) version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources.
