I deleted tailwind-merge from production

I deleted tailwind-merge from production While auditing dependencies in my monorepo, I ran an experiment that bothered me more than it should have: twMerge('border-grid border-red-500') // => 'border-red-500' border-grid is a custom utility defined in my component library's CSS. tailwind-merge has never heard of it, so it does what its heuristics say: anything shaped like border-<something> that is not a known width or style must be a border color. Two border colors conflict, the later one wi

当“小野猫”遇上“UFC表哥”：一场关于深夜醉酒短信的翻译美学实验

前言：文本背景解密首先，让我们把这段话写在黑板上，并给它做一个极其不情愿的“语法纠错”：原视频/原文本： "Baby I pay I you tonight. What's go on you little wild cat. Kate what the hell. The way that's your name if imma. My cousin is mma fighter. He fight ufc for sure. He training on aka. You know the gym have that good fighter you know. Yeah yeah." 背景脑补：这段话融合了“夜店搭讪”、“吹牛炫耀”、“家族背景展示（？）”以及“硬核格斗科普”。最亮眼的是，他提到了 AKA（American Kickboxing Academy，美国顶级格斗抱摔天团，出了哈比布、DC科米尔等神级选手的武馆）。为了完美呈现这段话在不同语境下的神韵，我们准备了四种完全不同画风的翻译版本。适用场景：凌晨两点，工体、蹦迪卡座、或某酒吧门前的马路牙子上。

Building a signed handoff protocol for AI coding agents

Building a signed handoff protocol for AI coding agents If you run more than one AI coding agent, you've hit this: Claude Code (or Codex, or whichever) gets deep into a task, hits its usage limit, and everything it knew evaporates. The plan, the half-finished edit, the "don't redo this migration" context. You paste a summary into the next tool by hand and hope you didn't forget anything. I got tired of that enough to build Relay: a Go daemon that sits in front of whichever agents you run and t

Blinding the State Informant: How Axiom Shield Weaponizes Client-Side Sandboxing Against EU Chat Control

The regulatory push for EU Chat Control 2.0 has exposed a fundamental architectural vulnerability in modern operating systems. Governments have realized that while breaking End-to-End Encryption (E2EE) at the protocol level causes massive public backlash, they can simply bypass encryption entirely by enforcing Client-Side Scanning (CSS) hooks directly on your physical hardware. Axiom Shield (v1.2.0) - an independent, non-commercial desktop workspace engine designed to enforce structural, client-

A founder once asked me why refunds kept disappearing, here is what NestJS was actually doing

A founder once messaged me with a problem that sounded almost too simple to be real. Customers were saying they never received their refund. Support would check the payment provider's dashboard, see the refund clearly marked as processed, and tell the customer it was sent. The customer would insist it never showed up. Both sides were technically right, and that is exactly what made it so hard to track down. The refund had genuinely gone through on the provider's side. What had not happened was a

My build in public journey: creating an Ebook generator

I once spent three weekends writing a single ebook for my Python course. Last month, my product (Ebookr.ai) generated a better one in about fifteen minutes, while I was making coffee. This is the story of the gap between those two sentences. I run Jornada Python, a Python course for Brazilian devs. Ebooks are great assets for a course business: lead magnets, bonus material, complementary content. Students love them. The problem: I hated making them. Writing was slow. Formatting was slower. And I
