Gonna be geeking out at BugBash this year, running a session on what the world might look like without traditional code review 👀
It’s a small, deeply technical conference on software reliability in DC. If that’s your kind of thing, come hang: bugbash.antithesis.com

Thanks! It’s been a dream come true to be honest!
LLMs can write code, but their tests tend to self-affirm the patterns they created. My current research is to teach agents to think in properties and let @antithesis.com automatically test the software. It’s still early, but already showing promise! antithesis.com/blog/2026/ag...
I use Hegel to help test Splinter github.com/orbitinghail...
Getting all that Hypothesis goodness via a rust shaped PBT library is amazing. And if you want to get started quickly they even have an AI skill that I used: github.com/hegeldev/heg...
I'll be in SF this week if you want to hang out! Or just come and see me at PWL! It's gonna be a sweet talk.

they keep referring to my creation as This. i don't know what it is either. it changes every time i look at it, squirming, writhing like a lamb caught in many mouths, the abalone surface of a bubble. it quivers with uneasy kinetic energy like the face of a child on the verge of tears
This is so good! Really fantastic read. Valeria has my vote for best debut blog in the bloggies!
Def going to be trying out daggerheart this year I think. I really love their approach to classes and the hope fear mechanic is neat. Probably will still yolo encounters tho :)
"It's about 25 minutes out of date, so it's missing nearly half the features."
vibe coding is pretty nuts yall
It's such a good quote! But nw, that's what reposts are for :)
Thanks for the awesome article!

If you’re trying to interface rust and c++ this blog post might give you some neat ideas!
Check out my talk on physical replication and Graft that I delivered at the recent @syncconf.bsky.social in SF. youtu.be/QoKzDyH2MEA?...
Thanks!! Are you at SyncConf? Come say hi!
I just wrote an article on my experience playing the collaborative storytelling game Microscope: Chronicle. It's written by @lamemage.com and is in playtesting now!

Full lineup and schedule for @syncconf.bsky.social in SF on Nov 12. Link in the 🧵 below 👇
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
Honored to be speaking at SyncConf this November! The line up is stacked!
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 :)
What if your test system could find bugs you didn’t anticipate?
Meet Antithesis: deterministic simulation testing for the rest of us. It changed how I test—and build—Graft.
This post covers DST’s origins, how Antithesis works, and what it taught me. sqlsync.dev/posts/antith...
Splinter would be a cool talk. Will give me a reason to SIMD accelerate it :)
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!)
Let me know what you think! Enjoy :)
My vancouver.systems talk is up! It's a deep dive on Graft—a transactional storage engine providing lazy, partial and strongly consistent edge replication.
Thanks to Cameron Morgan and Kir Shatrov for hosting
and @tavis.damnsimple.com for video!

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
What if your app could combine the simplicity of physical replication with the efficiency of logical replication? Meet Graft: lazy, partial, strongly consistent edge replication.
