Goal

Chinese version: 面向产品工程师的精益数据分析

Continuing the product engineer career path discussion, this article helps software engineers build a basic product thinking framework:

1. What validation stages does product innovation usually go through?
2. What qualitative judgment should be made at each stage?
3. What quantitative metric can be used to validate that judgment?

This article draws on Lean Analytics, a book on validating innovation that also helps engineers develop product thinking.

Recommended by Kevin Weil, Dan Martell, Fan Bing, Zhang Ximeng, and Ding Lei.

Goal

Chinese version: 产品工程：传统 SDE 在 AI 时代的可能职业方向

Explore one judgment: product engineering may be a new direction for traditional SDEs in the AI era.

• How AI affects the traditional SDLC
• Where SDEs can move their capability focus in the AI era
• How to build product engineering capability

Goal

Chinese version: 全栈视角下的后端技术栈地图

Get a fast overview of full-stack architecture, with a focus on backend systems.

1. A high-level architecture and technology stack map for full-stack projects.
2. A flash-sale e-commerce case study to connect the architecture with key backend technologies.
3. Practical references for project technology selection and architecture design.

Background

Chinese version: 我进入 AI 领域的方式，以及 Agent SDK 的设计

This article is about how to enter a new field quickly. The method used here is seeking truth from facts, with three steps: investigation, practice, and iteration through review. The concrete example in this article is agent engineering in the AI domain.

• Investigation: what problems appeared when entering the AI field, how to approach it, and what initial assumptions were formed through investigation
• Conclusions: what core judgments were formed after investigation and practice
• Practical engineering: how those judgments were derived, designed, and validated through a real agent engineering project

概览

• 前端检查
• ir生成
• recompose判断

概览

Compose compiler是compose框架的一部分, 本质是一个kcp(kotlin compiler plugin),用于支持编译期针对compose特性进行静态检查和代码生成.

在进入compose的编译之前, 需要事先对kotlin的编译架构、过程以及概念做一些探究储备
