Me, writing my PhD thesis 15 years ago: “I hope someday we’ll have a better editor for LaTeX.” AI in 2026: “Here’s a beautifully formatted 4-page LaTeX PDF. Oh, and by the way, it contains a Fields Medal–level proof of a Millennium Prize Problem.”

Given how high the bar is just to understand Navier–Stokes, I can only imagine how many tokens are currently being burned in data centers trying to solve the Collatz conjecture.

I listen to a lot of podcasts, but skip most episodes. I really only want to hear a handful of people like Jensen Huang and Gavin Baker. Yet I have to follow dozens of shows just to not miss them. So I built an iOS app. Attunex lets you follow people, not jut shows. Every episode they appear on, across any podcast, lands in one feed. Here's what that looks like for Jensen: attunex.app/p/jensen-huang Available on the App Store: apps.apple.com/us/app/attune…

Best investment ideas are hidden in your error logs. Engineers think they’re debugging production issues. Actually, they’re reading Wall Street research in monospace. ⸻

codex is actually the best Remote Desktop solution

Chatbox is not sticky. Coding agent is sticky. Memory, logs, repo context, and interaction style compound over time. That accumulated context is the product.

True fatherly love is giving all your Claude Code quota to your kid to build games, while you go back to last year’s workflow: hand-write coding using VS Code.

This is not a human error, Claude is shipping itself.

Claude Code is AGI for software engineer

Companies using Claude Code: “Productivity boost, layoffs planned” Companies not allowed to use Claude Code: OpenAI: “Hire more people” xAI: “Rebuild it, it wasn’t built right”

当年有幸试用过师兄的产品,现在想想确实太早了,对于预测下一个token的这个能力的想象力不足。

Codex App Server is a very under-mentioned feature: it runs locally as a server exposing the full Codex agent runtime. That means you can build any interface on top of it. The Codex app and CLI are just clients. I’m building a two-panel Electron app(using codex, and connecting to code app server) for my kid: Left: chat (or voice) with the computer Right: realtime HTML game rendering My kid can literally tell the computer what game he wants, or what feature he wants and it just works 🎮

Actually I just built a chatgpt app(using codex and connecting to codex app server) for me and especially for my kid, the only desktop we have at home is 2015 iMac using intel chips, most AI apps does not support it. The best part? I can keep adding new features using codex.
