If you're interested in #TTRPG games, I wrote an article on Grimwild. This innovative game combines some of my favorite Blades in the Dark systems with cinematic heroic fantasy. Check it out here: drosmir.com/blog/thought...

Carl Sverre @f0a.org of SQLSync is speaking at Sync Conf 2025 on partial replication.
He takes a slightly contrarian view: no CRDTs, but instead block-level replication. Hear all about it on Nov 12.3

Sorry for the delay! NATS Jetstream is a cool solution, however only solves part of the problem. The Graft architecture depends on a versioned pagestore layer which is independent from the log. Also I'd like the Graft core to only take a dependency on object storage for simplicity and robustness.

Haha, yup! It’s my latest baby :)

Fantastic post detailing Figma's sync engine. IMO one of the biggest success stories for real time sync in an application. So cool!

I have! They are certainly innovating, however the implementation has a lot of limits and doesn’t support the replication side of the story. But still very cool!

Graft is very much aligned with that idea!

Btw we should chat :) so much alignment between s2 and graft. I’ll dm

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 but if you get weirdly excited about error handling and Rust like me consider taking a look and sending me your thoughts.

Thanks @b5.bsky.social! I actually started with the "Code" term but changed to Fingerprint later which felt a bit better to me. But it's still very up in the air. Appreciate the feedback!

New blog post! I wrote about how I use GitHub contributions as another source of motivation when working on solo projects. Specifically I added a mini GitHub contribution graph to my Polybar (system taskbar).
