I strongly believe there are entire companies right now under heavy AI psychosis and its impossible to have rational conversations about it with them. I can't name any specific people because they include personal friends I deeply respect, but I worry about how this plays out.

I lived through the great MTBF vs MTTR (mean-time-between-failure vs. mean-time-to-recovery) reckoning of infrastructure during the transition to cloud and cloud automation. All those arguments are rearing their ugly heads again but now its... the whole software development industry (maybe the whole world, really).

It's frightening, because the psychosis folks operate under an almost absolute "MTTR is all you need" mentality: "its fine to ship bugs because the agents will fix them so quickly and at a scale humans can't do!" We learned in infrastructure that MTTR is great but you can't yeet resilient systems entirely.

The main issue is I don't even know how to bring this up to people I know personally, because bringing this topic up leads to immediately dismissals like "no no, it has full test coverage" or "bug reports are going down" or something, which just don't paint the whole picture.

We already learned this lesson once in infrastructure: you can automate yourself into a very resilient catastrophe machine. Systems can appear healthy by local metrics while globally becoming incomprehensible. Bug reports can go down while latent risk explodes. Test coverage can rise while semantic understanding falls. Changes happens so fast that nobody notices the underlying architecture decaying.

I worry.

现在很多人在用Claude Code ，但大部分人其实只用到了它很小一部分能力。

GitHub 上有人专门做了一个项目，把 Claude Code 怎么用、怎么配置、怎么选工作流，全部整理成了一份系统化的指南，叫 claude-code-best-practice，

目前已经 3.2 万 Star 了，连 Claude Code 的创造者都在推特上多次引用。

干的事情很简单：把 Claude Code 的各种使用技巧、工作流、配置模板，系统化地整理成了一份完整指南。

目前收录了 86 条以上的实战技巧，不是翻译官方文档那种，而是社区真实踩坑后总结出来的经验。

Agents、Commands、Skills、Hooks、MCP Server、Subagents，每个模块都有现成的模板，Clone 下来直接往自己项目里搬就行。

我觉得最有价值的是它做了一个主流工作流的横向对比。Everything Claude Code、Superpowers、Spec Kit、Get Shit Done 这些热门方案，每个的侧重点、Star 数、核心特色都标得很清楚。

简单说就是：追求代码质量选 Superpowers，追求速度选 Get Shit Done，想要全家桶选 Everything Claude Code。

还有个 Hot Features 表格，实时追踪 Claude Code 最新的 Beta 功能，比如云端规划 Ultraplan、后台自动权限确认 Auto Mode、macOS 屏幕控制等等。

一位工程师老哥做了一件号称30年没人做成的事：

让网页上的文字像杂志一样排版，文字绕图流动、多栏分布、适配任意形状，120帧丝滑。

他写了一个叫Pretext的库，完全绕过了浏览器的DOM排版系统。以前网页要知道一段文字多高多宽，必须把它塞进DOM让浏览器算一遍，这个过程极其昂贵。Pretext用纯数学自己算，快了500倍。

听起来像底层技术不关你事？但如果你用过任何网页编辑器、AI生成的UI、或者在浏览器里做过排版，卡顿的根源就在这里。这东西一旦普及，网页的表现力会跨一个时代。

Building a mobile game for 10M players. You need a real-time leaderboard for the top 10k.

Your SELECT * FROM scores ORDER BY score DESC LIMIT 10000 query runs thousands of times/sec with 1M concurrents.

Your DB CPU hits 100%, and the game lags for everyone.

How do you design a leaderboard that can handle this scale?

The latency between even two "nearby" regions like us-east 1 and 2 is ~18ms. us-east-1 to us-west-1 is closer to 60ms.

This advice is spot on. Do yourself a favor and keep your database in the same region as your other infra.

Better yet, same AZ!

@ezzz_au “The people you love, a part of them lives on with you. They see the world through your eyes. They feel what you feel. So you gotta live for them too. You gotta live a big life for them. Because you're the only one who remembers them. So you live, and you live big for them”

今天安排了一場臨時的技術面試，B輪新創，對於整個面試體驗是好的，面試官是UC Berkeley CS畢業的，問的問題不是Leetcode，是寫一個簡易的command line argument parser，感覺面試是著重於如何清楚溝通跟思考解法，我最感興趣的是最後他問了如果有其他的人使用了我實作的class，要如何避免他感到意外

晚上陪小孩睡，早上陪他起床，陪他玩，陪吃早餐這些看起來好像都是很平常的事，我心裡其實充滿感激生活所帶來的一切讓我有機會好好體會養小孩這件事😌

[Vic Yang @vrootic]

覺得還是要隨時準備好面試，臨時找工作實在是太可怕

入職後，在某次午餐時間，team裡面的某個人問我說所以你也是leetcode很久後才進來嗎？我回：「對啊，這個環境要的不只是刷題刷好，即使寫出來了，聊天中有點問題都會被刷掉」，現在回頭想想還真可怕啊
