started playing with coding agents and immediately wanted a nicer way to manage multiple agents each isolated to their own working sandbox - so I created KĹshĹ. check it out and lmk what you think :) happy weekend projects!.

RT @schickling: @arnabch20k @livestoredev That's a great question. The answer is that sufficiently complex apps often accidentally "turn inâŚ.

Stoked to see LiveStore launch! It's a really interesting app sync solution that absolutely nails a lot of the issues I talked about in Nice job @schickling!.

RIP webcam (2020â2025). You survived the pandemic, countless meetings, awkward small talk, and painful "no, you go ahead" moments. You'll be missed. Taking recs for a worthy replacement.

As Will said in the launch, I was the guinea pig to see how well self-serve would go. While there are some rough edges, itâs like any other early-stage or open source project. But once you go Antithesis you wonât go back :). Read about my experience here:.

We have a new product offering that produces an insane amount of value for people willing to endure a little bit of pain. So to try it out we're looking for people who endure pain professionally (i.e. founders):

Always a pleasure nerding out with @aarondfrancis. Graft is my attempt to rethink syncing data to the edge. Partial, lazy, consistent. Watch the deep dive đ.
I had another great talk with @carlsverre about his new project: Graft. Itâs designed specifically for lazy, partial replication with strong consistency, horizontal scalability, and object storage durability. Incredibly fascinating.

What if your test system could find bugs you didnât anticipate?. Meet @AntithesisHQ: deterministic simulation testing for the rest of us. It changed how I testâand buildâGraft. This post covers DSTâs origins, how Antithesis works, and what it taught me.

Thanks for highlighting Graft @simonw! If you don't already follow Simon I highly recommend you fix that. They work on open source tools like Datasette for data journalism.
Graft is a really interesting new open source replication system designed for read-write multi-leader replication, with a SQLite extension as the first demonstration of what it can do

Is anyone planning on going to @rustconf this year? I'm considering A. attending and B. submitting a talk about one of my open source rust projects (Culprit? Precept? Splinter? Graft? SQLSync? . vote now!).

My talk is up! It's a deep dive on Graftâa transactional storage engine providing lazy, partial and strongly consistent edge replication. Thanks to @cameron_p_m and @kirshatrov for hosting.and @tavisrudd for video!.

To celebrate the beginning of 2025 I implemented a error handling pattern that's been living rent free in my brain for too long. It's far from complete/documented/tested/etc but if you get weirdly excited about error handling and Rust like me consider taking a look and sending me.
