Application Level Homoiconicity

"Malleable software bends but doesn't break. Encoding behavior as data is a natural fit for sync engines and provides a fine-grained boundary for developers to safely expose parts of the application."

My self-sovereign / local / private / secure LLM setup, April 2026

"I have started to think about the question: what kind of AI setup would we build if we took privacy, security and self-sovereignty as non-negotiable? All LLM inference local first. All files hosted locally. Sandbox everything."

The Real Ambient Scribe Question is Trust, Not Note Quality

"We’re now close enough that you can build a credible local-first scribe workflow prototype in the browser, and once it exists, the conversations get better."

Building Aether: Architectural Breakdown of a Local-First P2P Messenger

"The goal was to build a strictly local-first software architecture. If two devices are on the same network, they should be able to discover each other and communicate directly—no cloud, no central databases, and no intermediary nodes. Here is a technical breakdown of how I built an architectural MVP of a decentralized P2P messenger using Electron, React, and libp2p, and the engineering bottlenecks I had to solve along the way."

Local First – How To Build Software Which Still Works After the Acquihire

"Alex Good discusses the fragility of modern cloud-dependent apps and shares a roadmap for 'local-first' software. By leveraging a Git-like DAG structure and Automerge, he explains how to move from brittle client-server models to resilient systems where data lives on-device. He explores technical implementation, rich-text merging, and how this infrastructure simplifies engineering workflows."

Your File System Is Already a Graph Database

"A file system with markdown and wikilinks is already a graph database. Files are nodes. Wikilinks are semantic edges. Folders introduce taxonomy. You don’t need a special MCP server or plugin. The file system abstraction is the interface, and LLMs are surprisingly good at navigating it." See also HN discussion

🛠️ Tools & Resources

A Technical Blueprint for Local-First AI with Rust and Tauri

"This project began as a personal side experiment to explore the feasibility of running modern LLMs entirely offline using Rust and Tauri. It is not a finished product, but a prototype and a living proof of concept."

What’s new in Gemma 4

"In this video, Olivier Lacombe (Group Product Manager, Google DeepMind) introduces the Gemma 4 model family. We also showcase multiple demos of Gemma 4 being used across a wide variety of hardware, from mobile to laptops."

Modern SQLite: Features You Didn’t Know It Had

"Write-ahead logging (WAL) is a journaling mode that improves concurrency and performance for many workloads. Readers don’t block writers, and writers don’t block readers in the common case. [...] For desktop apps, local-first tools, and small services, WAL mode can dramatically improve perceived performance while keeping SQLite’s simplicity and reliability." See also HN discussion

✨ Apps

"Manual sync for ultimate security and privacy: Unlike other tools, SheetLink never runs in the background. You click 'Sync Now' when you want to update your data. No surprises, no automatic access to your accounts."

Google quietly launched an AI dictation app that works offline

"The app is free to download, and once its Gemma-based automatic speech recognition (ASR) models are downloaded, you can start dictating on your phone."

Opensidian

"I built Opensidian as an open-source proof of concept: what happens when you store notes as Yjs CRDTs, sync them across servers, encrypt them end-to-end, and put a POSIX-like filesystem on top?"

formAIt

"Local AI document cleanup that turns raw inputs into structured docs." "Runs LLaMA.cpp locally with GPU acceleration when available, guided by a prompt that focuses on structure over creativity."
