Hey Community,

We explore Grok Build, the new terminal-based TUI coding agent from x.ai. We also look at Appless, an experiment from the creators of OpenUI that bypasses chat bubbles to stream live native UI components using openui-lang.

Finally, we dive into Maestro MCP, a new tool context protocol server that lets AI agents automatically build and run YAML test flows from plain English instructions.

If the Rewind made you nod, smile, or think "oh… that's actually cool" — a share or reply genuinely helps ❤️

i'll go first. i was writing .then().catch() chains for like two years before i actually started using async/await. i knew it existed, i'd seen it in tutorials, but my code "worked" so i never bothered switching. then i refactored an old project and realized half my bugs were from mishandled promise chains that async/await would have caught immediately.

also took me way too long to start using optional chaining. i had nested ternaries and && checks everywhere like some kind of animal. the day i discovered user?.address?.city i mass-replaced like 40 lines across a project.

what's yours?

This is not about UI, read more if you are into DAGs, Declarative Programming, or if you just like to do things differently
