I did a system design interview today. And whilst they didn't ask this question, I offered to show them anyway.
This is a system design 'interviewer' app.
It uses Excalidraw but with a bunch of features on top. The agent provides a technical brief, and then you can use the agent in voice mode and it will draw the diagrams for you based on what you say. It can't help fill in gaps or suggest things, because thats cheating!
It's purely a 1:1 draw what I say. After you finish, it will interview you, score your result and provide feedback where there are any gaps in your design.
Hey @ChatGPT @OpenAIDevs @thsottiaux How come Codex can't use the browser directly if you launch voice mode? This is a big problem for me, I want to discuss things on websites and do interactive things, but I can't, because its forced to use subagents??? These are openai defined system prompts...
HOW FAST IS CODEX CURRENTLY?
I decided to run a small bench with my agent against the Codex CLI.
The results surprised me... check comments to see more 👇🏻
I used to love Gyazo… until I had to pay just to access my own files sitting on servers in other countries.
So I built capz.dev
Capz is a native macOS app that hooks straight into the built-in screenshot tool (no new keybinds, no workflow change).
Every capture lands in your private cloud, stays organised + searchable, and gives you clean share URLs when you need them.
Your screenshots. Under your control.
Thats the vision anyhow. You can try Capz today, but I will be open sourcing this app soon so it's truly under you control and in your own private cloud!
Hey @elonmusk @spacexai @cursor_ai You guys should register a new domain TLD and offer free domain names for peoples projects - those on your annual plans!
GPT 5.6 Sol is great, but as you may have noticed... it tends to just over engineer things way too hard. Even the simplest of code tasks end up being a whole framework sometimes!
I think I've found a solution though... ponytail.dev
Have any of you guys tried Ponytail?

Wow, @CyberpunkGame Brain Dances are becoming more and more real each day!! 🤯
Re-shoot an existing video from a new angle 🤯
Truly insane work from @theworldlabs, this new model is a game-changer.
The initial clip was filmed with three cell phones on tripods - the model reconstructed a full view of the scene to reframe the video.
