长出手来：Agent 的三次进化，和它正在走向的地方
Growing Hands: How Agents Evolved, and Where They're Heading
我们对 AI 的想象，正从「对话」换成「托付」。这篇梳理 Agent 如何一步步长出手、2026 上半年马具与协议之变、它为何还不是靠谱员工，以及真正的瓶颈正从「能力」滑向「治理」。
Our picture of AI is quietly shifting from conversation to delegation. A plain-language map of how agents grew hands, the 2026 turn toward harnesses and protocols, why they still aren't reliable coworkers, and how the real bottleneck slides from capability to governance.

给 AI 装上"护栏"：什么是 Hook
Guardrails for AI — What Is a Hook?
跟 AI 说话是叮嘱，给 AI 设 Hook 是上锁。Hook 就是在别人流程的关键节点上挂一个你自己的动作——在 AI 每次真正触碰现实的那一刻，插进一道你说了算的关卡。
Talking to an AI is a request; setting a Hook is a lock. A Hook is your own action hung at a key node in someone else's workflow — a checkpoint you fully control, inserted at the exact moment the AI reaches out to touch the real world.

三万英尺
Thirty Thousand Feet
飞得够高就没有阴天了——这话在三万英尺是对的。但云并没有消失，它还在下面下着雨。真正的智者不是飞起来的人，是那个在阴天里替别人多撑一会儿伞、没有走的人。
Fly high enough and there are no cloudy days — true, at thirty thousand feet. But the clouds haven't vanished; it's still raining down below. The wise one isn't the person who flew up, but the one who stayed to hold an umbrella a little longer for someone in the rain.

最后的稀缺品
The Last Scarcity
历史上的革命都在争夺分配权——谁来分那些不够分的资源。AI 革命争夺的却是"被需要"的资格。当毁灭性能力像火柴一样人人可得，管制会达到顶峰，物质的政治让位于意义的政治。
Every past revolution fought over distribution — who gets to divide what isn't enough to go around. The AI revolution fights over something new: the right to be needed. When world-ending capability becomes as common as a matchstick, control peaks, and the politics of matter gives way to the politics of meaning.

没有谁可以在原地等你
No One Will Wait Where You Left Them
父亲用一支笔，把等待伪装成充实。我以为"以后"是仓库，长大才知道那是河——它从不欠谁，只负责流走。
My father uses a pen to disguise his waiting as a full life. I thought "later" was a warehouse; growing up, I learned it is a river — it owes no one, it only flows away.

它出念头，我出失眠
It ideates, I lose sleep
AI 一秒钟给我一百个念头，我才看清：念头从来不稀缺，稀缺的是那一下心头微动。它交出可能性，我交出半生——这买卖，暂时还算公道。
AI hands me a hundred ideas a second, and only then did I see it — ideas were never scarce. What's scarce is that small stir of the heart. It offers possibility; I offer half a lifetime. For now, a fair trade.

一句话概括 Copilot 与 Codex 的关系
Copilot and Codex in one sentence
同源、异路、现在正面竞争——Copilot 当年靠 Codex 起家，如今却分属微软和 OpenAI 两家，而"Codex"这个名字本身还被复用过一次。
Same origin, diverged paths, now competitors — Copilot grew out of Codex but now belongs to Microsoft while OpenAI revived the "Codex" name for an entirely different product.

Shadowsocks 技术速记
Shadowsocks — A Technical Primer
从协议设计、组件分工到 Ubuntu 部署清单——ss-libev + Privoxy 的最小可用配置，以及为什么 SS 在 DPI 演进面前需要叠加伪装。
Protocol design, component roles, and a minimum-viable Ubuntu deployment of ss-libev + Privoxy — plus why plain SS needs obfuscation layers in the age of active probing.

frp 内网穿透 RDP 准点 180 秒掉线之谜
The 180-second RDP drop on frp tunnel
tcpMux 接管了保活，应用层心跳却仍被 frps 当看门狗——两套保活机制相互不知情，便有了准点掉线的灵异现象。
When tcpMux took over keepalive but frps still ran its own application-layer watchdog — two liveness mechanisms unaware of each other, and a clockwork disconnection was born.

共产主义的条件
Conditions for communism
先抄一遍马克思的原话，再想一想，那个社会到底要什么样的物质与人才能存在。
First copy out Marx's own words, then ask what kind of material base and what kind of people that society would actually require.
