一、先定方向：为什么要 SRE

Recently, I've been taking a Udemy course to learn about Terraform. The course explains the core paradigm of writing Terraform code while using Terraform to manipulate Azure resources. I also decided to take this opportunity to learn as much about Azure as possible, so I looked through the self-study materials for the Azure Developer Associate certificate. The materials mainly focus on theoretical knowledge, but also include hands-on coding and command line operations. There are also multiple-choice questions. I've always thought that obtaining a certificate doesn't necessarily mean you'll be able to actually build or code software in the real world, as defined by the certificate's subject. I still think that, but I've found the certificate questions to be difficult. In fact, if I were to obtain the Azure Developer Associate certificate, I would have to spend time memorizing the details of Azure services, and the certificate questions are not completely unrelated to software construction and engineering.

Pitfalls of running an npx-based MCP server on Windows

I've been seriously trying to use MCP server for the past 2 days. Today, I successfully completed a small demo task using the coding agent plugin - Roo Code on VS Code. Here are some specific steps and pitfalls you're likely to encounter.

I added 2 MCP Servers in Roo Code, namely:

Initially, the "Filesystem" MCP server wouldn't run because I was using VS Code in Windows with PowerShell. If you're also a Windows user, you'll likely encounter errors running Node.js-based MCP servers. You can refer to the following two posts to resolve the issue:

Running a public server from WSL 2

Forward from: https://www.williamjbowman.com/blog/2020/04/25/running-a-public-server-from-wsl-2/

2020-04-25 :: linux, tricks, windows, wsl

This week, for ReAsOnS, I wanted to run a server on WSL 2 that was accessible from the internet. This was surprisingly involved and requires lots of hard-to-find tricks to forward ports through 4 different layers of network abstractions and firewalls.

In WSL, make sure your server is using IPv4. I spent a hell of a long time just trying to figure out why I couldn’t access the server from localhost. I had successfully run a handful of local http servers from WSL that were accessible from the Windows host, so I wasn’t sure what the problem was. It turns out this server, written in Java, wouldn’t work until I added -Djava.net.preferIPv4Stack=true to the java options. It appears that Java was defaulting to IPv6, and WSL doesn’t forward IPv6 properly, or something.

通过搜索以及向New Bing提问，解除了我的一些疑惑:

需求分析是软件生命周期中的一个阶段。软件生命周期包括: 需求分析、架构设计、详细设计、编码、测试、部署和维护。
"UML建模"可以在需求分析、架构设计和详细设计阶段使用，用于描述软件系统的静态和动态特征。
在详细设计阶段之后，应该就产出了与具体代码密切相关的产物，比如类图、序列图、活动图等文档。
