TanStack DB 0.6 Now Includes Persistence, Offline Support, and Hierarchical Data

"With v0.6 of TanStack DB, we're bringing some highly anticipated features and improving the ergonomics for app development. You can now project normalized data into the same hierarchical shape as your UI, persist local state across runtimes with a SQLite-backed layer, and trigger reactive side effects directly from live queries. Row metadata unlocks outbox views and delivery indicators (think WhatsApp-style), and APIs that previously relied on implicit behavior are now explicit and consistent."

QCon London 2026: Kleppmann on Mitigating Europe's Cloud Dependency with Local-First Software

"For collaborative tools, Kleppmann described local-first software as the combination of the best of Google Sheets (rich data, real-time collaboration, usability) with the best of Git (version control, branching, multi-provider hosting, files on your own machine). The core shift: the user's local copy of data becomes primary, with cloud services reduced to sync and backup. This minimizes the role of centralized servers, makes provider switching trivial, and even enables peer-to-peer sync."

How We Synchronized Editing for Rec Room's Multiplayer Scripting System

"Circuits is Rec Room's technology for programming rooms: a multiplayer-synchronized realtime scripting system that lets players build interactive experiences together. Creating Circuits is one of the top honors of my career. I'd like to share how we solved core networking challenges, for anyone working on similar problems." See also HN discussion

Talat’s AI meeting notes stay on your machine, not in the cloud

"He then stumbled upon a software toolkit called FluidAudio, a Swift framework that enables fully local, low-latency audio AI on Apple devices. It lets you run small, fast transcription models directly on the Mac’s Neural Engine — Apple’s dedicated hardware for AI processing. That was the piece that made Payne realize he could turn his research into an actual product — one where your audio never leaves your Mac and your transcripts aren’t stored on another company’s servers."
