A bunch of talks yesterday name-dropped Lustre which is so surreal, super wild for folks to just be talking about Your Thing ™️ in the middle of a talk.
We're only 18 stars off of 1.9k and I'm desperately trying to get 2k before the end of the year. 🥺👉👈

Update on my reactflow ripoff, we have properly functional handles and connections! I think almost all the fundamentals are here enough to publish a v1.
Before I do that it's time for a round of docs and polish ^.^

tonight i added panning inertia and rewrote how the core rendering works, i'm super pleased.
that's the fundamentals down i think, tomorrow is on to all the events required to implement real things. first up is connecting handles together.

You know how LLMs have a bit of a writing style and you can get a vibe for ai-generated text? I get the same feeling from ai-generated UI. It's got this uncanny valley vibe to it and once you start noticing the big padding, large border radius, bright colours, emojis, ... it's super jarring.

I'm thinking about wholesale ripping of @vuejs.org's long-form guide for Lustre. I'm guessing the overlap is quite small but do I know anyone who's worked through that guide and can remember any good/bad thoughts?

Suuuuuuuper excited to confirm that I'll be speaking again at @codebeam.bsky.social EU later this year. If you're a gleamlin or just gleam-curious just take a look at how many gleam talks there are this year 🤯💕

In the future, this may be optimized further. Of course, another way to handle lists is to use streams, but that's not always the solution.

Can you believe i tricked these chumps into letting me talk about testing 🫣 i’ve been building out some wicked testing apis for lustre, conf-driven-development is the way
Yes, it’s true — she did sneak in a talk about frontend #testing.
And we’re glad she did. @hayleigh.dev takes on slow CI, flaky tests, and shows how #functional #UIs (like #Lustre & #Elm) help us test smarter.
Catch it at #LambdaDays!

It always makes me feel weird when a cfp or a grant application wants me to describe how I'm under-represented or otherwise a minority in tech.
Logically I get it, but it feels so uncomfortable.. what do you mean you can't just magically ✨ Know ✨ ???
