Just because words form a sentence, it doesn't mean it has meaning.
Some sentences are like a blank puzzle. The pieces fit together, but it shows you nothing. Those sentences irritate me.

Oh wow, Zed supports select by semantic selection, like JetBrains (and unlike VS Code/Cursor).
Ok... I think I'm switching and seeing if it works.

Every time I pick up a new framework, I find myself replicating how the database and tests works in Rails. I wish the Rails out-of-the-box experience was more common.
This time it was NextJS, Prisma, and Vitest.

What things should be is good for philosophy, what things are is good for planning. Plan with how the world behaves, not how it ought to.

This weekend I changed directions with the experimental app that I'm building. I was using Convex, which I was enjoying, but realistically what I'm building doesn't need the sync system Convex offers, and I realized it needs PostgreSQL. #buildinpublic

Every company I worked at needed 10 times more engineering, 10 more code, 10 times more solutions, than they could afford.
LLMs will allow us to start tackling that.

I built a tiny sample application with #Convex and I think it's more complex than an app with one form, one table and 5 fields should be. I'd appreciate any feedback in how I can make it better (while still being sound):
