整理一下常见的 Docker Network 操作 Default Bridge Network After a fresh Docker installation, you can find a default bridge network up and running. docker network ls Docker uses a software-based bridge network that allows containers connected to the same bridge network to communicate while isolating them from other containers not running in the same bridge network. docker run -dit --name busybox1 busybox docker run -dit --name busybox2 busybox docker inspect busybox1 | jq -r ' [0].NetworkSettings.IPAddress' docker inspect busybox2 | jq -r '.[0].NetworkSettings.IPAddress' # OK docker exec -it busybox2 ping 172.17.0.3 # Error docker exec -it busybox2 ping busybox1 Conclusion All containers will automatically connect to this default bridge network. Default bridge network allows container communication using IP addresses. ...

Using Error Wrapping An error often “bubbles up” a call chain of multiple functions. In other words, a function receives an error and passes it back to its caller through a return value. The caller might do the same, and so on, until a function up the call chain handles or logs the error. An error can be “wrapped” around another error using fmt.Errorf() and the special formatting verb %w. ...

这里简单总结一下三种组合方式: interface 中嵌套 interface struct 中嵌套 struct struct 中嵌套 interface interface 中嵌套 interface 这种组合方式体现了接口隔离原则(ISP)和接口组合原则, 通过接口嵌套，我们可以构建更大的接口 // 基础读接口 type Reader interface { Read(p []byte) (n int, err error) } // 基础写接口 type Writer interface { Write(p []byte) (n int, err error) } // 组合接口 type ReadWriter interface { Reader // 嵌套 Reader 接口 Writer // 嵌套 Writer 接口 } struct 中嵌套 struct 这种组合方式体现了组合优于继承12的原则，是 Go 中实现代码复用的重要方式 // 地址信息 type Address struct { Street string City string Country string } // 用户信息 type User struct { Name string Age int Address // 嵌套 Address struct } // 使用示例 func main() { user := User{ Name: "张三", Age: 25, Address: Address{ Street: "中关村大街", City: "北京", Country: "中国", }, } // 可以直接访问嵌套字段 fmt.Println(user.Street) // 输出: 中关村大街 } struct 中嵌套 interface 这种组合方式体现了依赖倒置原则(DIP)，常用于策略模式的实现 ...

Concepts Each workspace contains its own single root node Each non-leaf node is called a “Container” Each container can contain arbitrary number of children nodes Windows are the only possible leaf nodes. Windows contain zero children nodes Every container has two properties: Layout (Possible values: tiles, accordion) Orientation (Possible values: horizontal, vertical) Some examples: In total, AeroSpace provides 4 possible layouts: h_tiles horizontal tiles (in i3, it’s called “horizontal split”) v_tiles vertical tiles (in i3, it’s called “vertical split”) h_accordion horizontal accordion (analog of i3’s “tabbed layout”) v_accordion vertical accordion (analog of i3’s “stacked layout”) Accordion is a layout where windows are placed on top of each other. ...

本篇 Blog 正在更新中 这篇 Blog 主要记录了一些在 Unix 终端环境下对应的 Windows 下的常见的鼠标操作 主要面向 Linux 和 MacOS 的新手们，所以有些信息会被简化或者忽略 可为什么要用终端/命令行呢？ 就像“为什么使用 Vim”一样，原因有很多，对于我来说，它足够简单，足够快，支持许多的自定义，是 Programmable 的 在程序员的世界里，你真的能够做到（抖个机灵哈哈哈）： 如果你觉得终端难用，就去定制你的 Shell 配置；如果你觉得命令不够方便，就写个函数或别名把它封装得更好；如果你觉得工具功能太弱，就用脚本扩展它的能力；如果你觉得操作繁琐，就从自动化开始，一点点改善工作流程，而不是一昧地抱怨，排斥，逃向 GUI。 Left Click 首先需要学习的肯定是鼠标左键的双击 — 打开某个文件夹，以及打开某个文件夹后的结果：查看这个文件夹的内容 对应到终端中： cd 跳转到某个文件夹 ls 展示文件夹的内容 > ls Applications Playground DataGripProjects Projects Desktop Public Documents Scripts Downloads Temp Dropbox Virtual Machines.localized Library Zotero Movies dotfiles-main Music go Pictures > cd Projects 在使用 cd 命令时，不用把文件夹的名字输入完整 比如想要 cd Projects，只需要输入 cd Pro，然后按下键盘上的 Tab 键，就能触发自动补全 ...
