The A100 Paradox: Why Aging GPUs Could Cost More to Rent zhuchang.substack.com/p/the-…
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

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 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 🎮
