Building a local-first music app @overtone_app with @livestoredev. Host @localfirstfm. DX @EffectTS_. Founded @prisma. https://t.co/74n8eMH4cs
Berlin, Germany 🇪🇺
Joined August 2009
Just recorded this little performance demo of @overtone_app while working on my talk for @localfirstconf. Near-zero query latency enables a magical UX.

My prediction from 3 years ago seems to be well on track. 2026 looks like the year where Effect hits mainstream with the tailwind of coding agents. 🔥
Prediction: Effect is going to be one of the most important web technologies in the next 10 years.

Effect + React + OpenTUI = match made in TUI heaven

This, plus TypeScript (specifically @EffectTS_ ) for everything where Rust doesn’t make sense, and then Bash for whatever is left.
rust is a perfect language for agents, given that if it compiles it's ~correct

Effect is the best „programming language“ for agents
@rauchg this is why i'm so bullish on effect, the new answer overflow codebase is fully on it and the feedback loop is incredible: - the agent can write tests w/ mocked services easily, it doesn't have to mess with jest mocks - it can just go pull in from the source the best patterns -

So I'm on the _intro_ and https://t.co/58SLvDpWzC is already the most compelling learning experience in recent memory. The attention to detail, alone. Incredible, @kitlangton.

while it teaches the science behind prompt caching, @samwhoo's blog post is, imo, the best intro to how LLM's work. filled with Sam's charm, animations, and ability to distill highly technical topics into engaging blog posts, this is well worth your time https://t.co/SyC4ysYRgC

A far more detailed explanation of prompt caching than anyone asked for.

Is there something like Fuse FS for @linear to map issues to local markdown files? Agents have a much easier time working with files than with MCP.

Fun convo with @schickling . We discuss: - Why Warp writes typescript - Why typescript sucks - How we found effect - Why we’re making a huge bet on it - How we’re incrementally adopting it Tldr: When building a pre-pmf product iteration speed matters most, often above
Cause & Effect #7 with @rankintweets, CTO at @joinwarp. We talk about using Effect to bring structure and composability to a growing TypeScript codebase, enabling a small, fast-moving team to stay productive while shipping reliable payment & payroll systems.

I've always been fascinated by React Native macOS, but it seems to have come a really long way and seems like a very compelling alternative to Electron. Anyone out there using it?
My talk with @SaadNajmi at @RNLConf is up! You might have seen me talking about React Native macOS a lot. This is my argument for why we should take React Native on desktop seriously and make apps good again✌️. And Saad shows off the cool new stuff! https://t.co/Sav9AjuRxp

Very excited to see more libraries and tools focusing on events and streams!
Today we're open-sourcing Durable Streams: a persistent stream primitive and HTTP protocol for reliable, resumable, real-time data streaming to clients. We built it inside Electric. Now we're standardizing it as a standalone protocol.

AI should remove friction, not resistance. Same as going to the gym where you don’t press a button to have the weights lifted for you.
A few things I've noticed as all devs write code with AI. When you write foundational / architectural code of a new project by hand, you "feel" the code pushing back if your abstraction isn't right. You feel when something is harder than it should be. The code is telling you

Is there some sort of spreadsheet tool that works well hand in hand with local coding agents? Basically, what is the equivalent of Google Sheets to Markdown?

This is absolutely crazy. Bought the Limitless Pendant less than a month ago and had to pre-pay for a year worth of service. Wtf.
I'm excited to share that Limitless has been acquired by Meta! Here’s why we joined forces, what this means for customers, and what comes next.
