What’s New pulls release notes and patch notes from across the software world — open source, games, operating systems, the apps on your phone — into a single feed you can read, search, subscribe to, and cite. A look at why the pages never wait on a third party, why almost nothing here is scraped, and why every entry tells you where it came from.

Corpusly indexes a Google Drive for semantic search and serves it to Claude and other MCP clients, with no vendor server anywhere in the data path. A look at the local embedding pipeline built on a quantized, in-process transformers.js model, the two-transport MCP server it’s served over, and the engineering it took to make ’nothing leaves the machine’ actually true: a memory blowout fixed by sub-batching, a stdout-corruption constraint solved structurally, and an OAuth scope decision that doubled as a compliance strategy.

Knit is a phone-to-phone messenger that needs no internet, no account, and no server to work: it talks straight to the phones around it over Wi-Fi Aware and Bluetooth LE. After a full rewrite it does that without Google Play Services either. A look at the dual-radio mesh, the wire protocol, and the on-device features that hold it together.

An installable Agent Skill that teaches a coding agent the dotagents standard: a slim AGENTS.md router plus a hidden .agents/ library, split by kind and loaded only when the current task matches. Built after watching my own CLAUDE.md files drift toward becoming the thing they were supposed to prevent.

How I built grandma.chat — a Next.js + AI Gateway chat app — with layered abuse defense, dual in-memory/Mongo backends, and a daily spend circuit-breaker.

A Godot 4.6 / .NET 8 narrative sandbox with two parallel deterministic world grids, a headless determinism test wireable into CI, and a debug-only HTTP introspection server built specifically for AI-assisted debugging — where there is no window to eyeball.

A multi-year personal-research thread: device-free human sensing from Wi-Fi Channel State Information — reproducing WhoFi as a metric-learning retrieval system, plus a graduated occupancy preprint with the kind of statistical scaffolding the field too often skips.

Building, packaging, and daily-driving a custom audio-tuned Linux kernel — XanMod base, hand-curated patch stack, ISA-targeted, packaged the proper Debian way — and the audio-stack work that makes it worth the trouble.

An architectural sketch of the platform shape I keep building for managed OpenWrt device fleets — admin portal, signed-config provisioning API, MQTT telemetry, Vault-backed secrets, and a Docker-isolated flasher with a safety flow operators actually trust.

A weekend that turned into a project: a clean-room software reimplementation of the Security+ and Security+ 2.0 garage-door rolling-code systems, framed as an RF reverse-engineering exercise.
