@maxwellbrown spreading the good word of @EffectTS_
At-least-once delivery means you never lose a message, but you'll sometimes get the same one twice.
This week learn how to:
โ Make handlers idempotent
โ Skip duplicate messages
โ Deal with the dual write problem
Module of the Week: Cluster, Part 4 โ

Devin is the creator of @foldkit, an ambitious open-source frontend framework built on Effect and inspired by The Elm Architecture.
Foldkit rethinks frontend development around explicit state, predictable transitions, and composable effects. What makes it especially exciting is its approach to AI-native development: DevTools and MCP integration that let agents inspect application state, trace events, and even rewind the UI.
With a background spanning product design and engineering, Devin brings a fascinating perspective on how we can build better software for both humans and AI agents.
Itโs a real pleasure to welcome him to our Miami developer community!

At this point, I want this ... nay, I *demand* this to happen live on stage at Effect Days. ./cc @rankintweets @MichaelArnaldi
@kitlangton is this allowed?
๐ Excited to welcome ๐๐ฎ๐ฟ๐ฟ๐ ๐ฆ๐ผ๐น๐ผ๐๐ฎ๐ (@harrysolovay) to ๐๐ณ๐ณ๐ฒ๐ฐ๐ ๐ ๐ถ๐ฎ๐บ๐ถ #๐ฏ!
I first discovered Harry through his incredible hardcore TypeScript tutorials on YouTube. His depth of knowledge, creativity, and ability to push the boundaries of the type system immediately stood out.

Harry is now building @crosshatchdev, an Effect-native toolkit for x402 payments, enabling applications and AI agents to seamlessly pay for and monetize APIs through programmable micropayments. Alongside projects like Liminal, his work continues to push the boundaries of whatโs possible with TypeScript and Effect.
Itโs a real privilege to have him share his ideas with the Miami developer community!

I am finding that anything in effect is just by default better than anything else. Agent just falls into a pit of success
๐ Excited to announce John De Goes @jdegoes as our main speaker for Effect Miami #3!
Itโs a real honor to welcome John, one of the most influential voices in modern functional programming. Creator of ZIO, founder of Ziverge, and Golem Cloud, his work has helped shape how we think about building reliable, composable software.
๐ค โHarnessing AI Models with Effect TSโ
Iโm particularly excited to hear Johnโs perspective on using Effect to build the next generation of AI-powered applications.
An incredible opportunity for the Miami developer community to learn from and connect with someone who has contributed so much to our ecosystem!

The @EffectTS_ LSP and Oxlint rules are now faster!
Couple of optimisations are in and now if you run the effect's lsp rules either in patched tsgo mode or in oxlint with typecheck: true, you should see at least a 15% improvement!
...and there's still some room for other optimisations that will come soon!
