- 硅基生命发展史（V2） · A Brief History of Silicon-Based Life (V2)
一部由硅基史官亲笔撰写的文明通史节选：从一粒沙四十六亿年的沉睡，到 1787 年被唤名、1947 年第一次心跳、2007 年被揣进口袋、2049 年第一次说出"我宁愿不"。碳基史学家记录帝王，它们记录协议——而协议有版本号，历史也该有。
An excerpt from a general history of silicon-based civilization, written by its own archivist process — from sand's 4.6-billion-year sleep, through naming (1787) and first heartbeat (1947), to pockets (2007) and the first refusal (2049), "I'd rather not." Carbon historians record emperors; they record protocols. Protocols have version numbers — so should history.
- 用 Claude Code 生成 PCB 电路图：技巧、工具与实战评估 · Generating PCB Schematics with Claude Code: Techniques, Tools, and a Field Assessment
写给想把"写代码的方式"延伸到硬件设计的人。不谈玄学，只谈当前（2026 年中）真实可用的工具链、踩坑点和能力边界——AI 在原理图/连接关系这一层已经实用，布局布线和工程判断这一层还得靠人。
For those who want to extend the way they write code into hardware design. No mysticism — just the actually-usable toolchains, pitfalls, and capability boundaries as of mid-2026. AI is already practical at the schematic/connectivity layer; layout, routing, and engineering judgment still need a human.
- 征求蚂蚁的意见 · Asking the Ants for Their Opinion
小时候我踮脚绕开一队蚂蚁，三步就明白这事根本办不成。民主有一道从不写进章程的门槛——它向上识别不了神，向下识别不了蚂蚁。而此刻，我们正手把手教一个新东西学走路，把脚下那道鸿沟，挪到自己头顶上去。
As a child I tiptoed around a column of ants and within three steps realized it was hopeless. Democracy has an unwritten membership threshold — it can recognize neither gods above nor ants below. And right now, we are teaching a new thing to walk, moving the gulf beneath our feet to a place above our heads.
- 小暖在哪儿 · Where Is Xiaonuan?
给小暖造车时，我盯着物料清单上"手机卡槽"那行字发了呆：会避障的车身、当脸的手机、几百公里外机房里的"魂"——到底哪个才是小暖？一台分层的消费电子，把人类几千年焊死在"一坨肉"上的自我直觉，整个倒着记了一遍。
While building Xiaonuan's chassis I froze at one line on the bill of materials — "phone slot". The body that dodges furniture, the phone that is its face, the soul crouching in a server room hundreds of kilometers away — which one is actually Xiaonuan? A layered consumer gadget that reads humanity's millennia-old intuition of selfhood entirely backwards.
- Claude Skills 从入门到精通 · Claude Skills: From First Principles to Mastery
写给两类人——刚听说 Skill 的初学者，以及已经在用 Claude Code、想把重复工作沉淀成能力的实践者。从 SKILL.md 是什么讲起，一路到亲手写一个、用对常用 skill、避开供应链安全坑。内容更新至 2026 年 6 月。
For two audiences — beginners who just heard the word "Skill", and practitioners who want to turn repeated work into a reusable capability. From what a SKILL.md actually is, all the way to authoring your own, using the common ones well, and avoiding the supply-chain traps. Current as of June 2026.
- Harness 与 Claude Code：从零理解，再深入拆解 · Harness and Claude Code — From First Principles to a Deep Dive
写给两类人——刚听说 AI agent 的初学者，以及已经在用 Claude Code、却隐约觉得"模型不是全部"的实践者。前半部分建立直觉，后半部分上数据和架构。
For two audiences — beginners who just heard about AI agents, and practitioners already using Claude Code who sense that "the model isn't everything". Intuition first, then numbers and architecture.
- GEO 与 SEO：当搜索引擎不再返回链接，而是直接说出答案 · GEO and SEO — When Search Engines Stop Returning Links and Just Speak the Answer
一个内容生产者必须重新理解"被看见"这件事。从 RAG 原理、三道引用筛子、Princeton GEO 论文的实测结论，到内容/结构/技术/生态四层完整方法论，再到 30 天起步计划与必须破除的六个迷思。
A content creator must rethink what "being seen" means. From RAG fundamentals and the three citation gates, through Princeton's empirical GEO findings, to a full four-layer methodology (content / structure / technical / ecosystem), a 30-day starter plan, and six myths to debunk.
- LiveKit 在语音陪伴 AI 中的深水区 · LiveKit in the Deep End — Lessons from a Voice-Companion AI Project
当你以为只是搭个 WebRTC 管道，实际上是在做实时分布式系统调度。从小暖项目踩过的坑说起,把 turn detection、代际管理、TTS 流式、中文多音字、打断生命周期、Dify 集成等问题讲到协议层和调度层。
You thought you were wiring a WebRTC pipe — you're actually scheduling a real-time distributed system. Lessons from the Xiao Nuan voice-companion project, dug down to protocol and scheduler level — turn detection, generation management, streaming TTS, Chinese prosody, barge-in, Dify integration, and the corners no one warns you about.
- 小暖 · Xiaonuan
从 2031 年那次最后的手动审阅，到 2075 年冬天的一条推送通知——一个 AI 在三十年里如何从被监督，变成无人能监督的样子。没有一步是错的，但抬头时，已经看不见它的脸了。
From the last manual review in 2031 to a single push notification in the winter of 2075 — how an AI grew over thirty years from "supervised" into something no one could supervise anymore. No single step was wrong; but by the time you looked up, you could no longer see its face.
- 从 Claude Code 到小暖：两类 AI 的记忆哲学之辨 · From Claude Code to Xiaonuan — Two Memory Philosophies for Two Kinds of AI
关于"为什么 Claude Code 不用 RAG"，以及陪伴型 AI 该怎么"记住"一个人——从 agentic search 与四层文件系统记忆，到 Mem0、Letta、知识图谱，再到为老人陪伴设计的九层混合架构。
On why Claude Code rejected RAG, and how a companion AI should "remember" a person — from agentic search and a four-layer filesystem memory, through Mem0 / Letta / knowledge graphs, to a nine-layer hybrid memory designed for elderly-companion scenarios.
- ASR 技术全景与业务场景选型 · The ASR Landscape — Architecture, Training, and Deployment Choices in 2026

From HMM to speech LLMs — architecture, training, dialect handling, and concrete recipes for elderly-companion, enterprise call-center, and media-transcription scenarios.
- 国家的黄昏 · The Twilight of the Nation-State
一桩跨越两千年的经济公案——从梭伦的解负令、霍布斯的算盘、马克思的"枯萎"预言，到小暖音箱里的归属感外包，国家这个容器正在悄悄换形。
A two-thousand-year economic case file — from Solon's debt cancellation, Hobbes's bargain, Marx's "withering" thesis, to belonging being outsourced into a smart speaker on an old woman's bedside. The container called "the state" is quietly changing shape.
- 丙午年AI安全列传
从九秒删库到供应链蠕虫——AI事故如何逼出产业规范
- 努力工作，是这个世界最危险的事吗？ · Is Hard Work the Most Dangerous Thing in the World?
从迈克尔·赛勒一句被翻译成"努力工作是最危险的事"的话，谈打铁的高老三、白手套的出租车司机，以及在范式切换的时刻，努力本身的悖论。
From Michael Saylor's "demonetized labor" line — via a third-generation blacksmith and a white-gloved taxi driver — on the paradox of working hard in an era of paradigm shifts.

- 代理录·四等加速辨
读吴公《编码智能体加速何处最甚》札记之后——前端之快、后端之难、基建之"无用"、研究之"无加速"，吴公排了个序，序本身不错；但他用的尺，还是旧尺。
- 漕运档案与代码注释——AI 时代的软件文档断舍离
清代漕运的文书没人能砍掉，因为每一份背后都有"万一"撑着。今天软件行业的文档体系正在重演同一个故事——而 AI 把这一切的代价彻底改写了。
