Evgenii Ray has used AI since the very first models. And even he's surprised by how fast it's improved. Two years ago it struggled with complex code. Now it actually understands patterns. That's not a small jump.

There is no `anchor` attribute in HTML, it was decided CSS `anchor-name` / `position-anchor` was the way to go. But modern CSS functions can get us there anyway.

@SandroDoesStuff Not that we're aware of. Email [email protected] if you're still having issues? They can look into it for you.

The barrier to querying your own data is almost gone.

Front-end devs can now load their Google Analytics into DuckDB, ask "which browsers have the most latency?" and get the answer.

You don't need a data scientist for every question anymore. You just need to know what to ask.

@AdamRackis @FrontendMasters I was there online. Learned a lot in such a short time! FE Masters has to be one of the best values out there.

[Adam Rackis @AdamRackis]

Hard to overstate how wonderful of a process @FrontendMasters is. The staff is incredibly friendly, and great at what they do.

Just wrapped my second workshop, and had even more fun this time. Hope to be back 😬

React Server Components in TanStack

RSCs in TanStack Start are server-only executed code — perhaps a significant improvement over the Next.js implementation.
