Svelte good a huge DX boost with remote functions. And grateful for @joyofcode.xyz to create a banger video explaining them, walking through the tutorial has been lots of fun.

Was looking into SvelteKit and got pretty far, pretty quickly in building a prototype of an app. with the help of AI.
However, I also got stuck, not understanding what I had actually build. Went back to rebuilding from scratch, making sure I understand each piece of code. There is a lesson here.

Details matter. Email input is active while opening the page. Button starts disabled, as the form becomes valid, the button transitions to being enabled. Only thing I don't like is that the button jumps because of the error message.

Vercel came out with their new domains app and its getting much praise for its snappy UI. Can we build an UI as polished with LiveView? Should be doable no? #elixirlang

I woke up and decided to write something to promote #ElixirLang more, since it brought us so much.

Elixir was our unfair advantage, then AI made it a cheat code.
We didn't plan for the AI wave, but Elixir's actors and supervision turned out to be exactly what modern AI agents need. Ship twice as fast, stay reliable.

Oban alone is worth switching stacks for. I haven't seen an as powerful, easy to run and polished background job processor in any other stack.

New #ElixirLang and Phoenix project checklist:
- Setup LiveDashboard
- Configure .iex.exs (auto_reload)
- Add Credo
- Add LiveDebugger
- Add Oban
- Add Tidewave
- Setup Fluxon (my components of choice)
Anything I'm missing?

Hear me out... what if we build replication of SQLite across the cluster with #ElixirLang and the primitives provided by the BEAM?
Instead of using external tools like LiteFS or the new Beamer project by Basecamp, we make it easy to use with Phoenix and Ecto.

The Zen Browser has come a long way. If you gave it a shot before and didn't like it, please try again. We could use more Firefox users out there to balance the scales.

Watched a video from a fellow developer about their journey in finding a TypeScript stack that manages real-time updates, streaming, and background jobs. It required multiple subscriptions.
In #ElixirLang, we often take for granted how seamlessly these features come with the platform.

Presentation on Beamer for SQLite was just released. It shows replication for SQLite databases and Rails apps. This is definitely something I would like to port over to Phoenix and Ecto for #elixirlang.

Loved DHHs presentation and the "Many Small Outposts".
As an #elixirlang dev, this concept resonates deeply, LiveView experience is so much better when users are close to the database. Great opportunity for the Elixir community to tag on this initiative and help.

I don't use Daisy UI for any of my #ElixirLang projects, but luckily, it's really easy to remove:

I like to keep a `NOTES.md` file within each project. My flow in Zed is that I now pin the file and then can quickly switch to it with CTRL-1.
