Securing a Public Chat Socket and a Desktop GitHub Sign-In
A live chat has two trust problems: anyone on the internet can open the visitor socket, and exactly one person should be able to answer. The cheap layers that keep an anonymous WebSocket from sinking a 1 GB server, and a PKCE-protected GitHub sign-in for a desktop app that never holds the OAuth secret.
Building a Live Chat Desk in C++: The Whole Architecture
A website chat that only says “online” when a real person is at their desk: a tiny site widget, a WebSocket relay, and a native macOS app with a C++17 core. Here is how the three pieces fit, and why presence is computed rather than stored.
Scheduling a Local LLM Under a Live Microphone
Two 7B models racing each other on a laptop don't just answer slowly — they starve the transcription queue. Priority lanes, same-model serialization, five resource gates, and a grounding contract that makes the output worth the heat.
Who Said That? Online Speaker Diarization With No Enrollment
Labelling speakers in a live meeting without voiceprints, registration, or knowing how many people are in the room — 256-dimensional embeddings, one cosine comparison, and a threshold that is a trade rather than a truth.
Spool It to SQLite First: A Durable Audio Queue for Local Transcription
When local inference falls behind a live microphone, the backlog has to live somewhere. Put it in an array and a slow model becomes a memory leak; put it in a table and it becomes a row count you can restart into.
RMS Is Not a VAD: The Two-Stage Gate That Stops Whisper Hallucinating
Whisper handed three seconds of HVAC returns a fluent sentence nobody said. The fix is not one filter — it is an energy segmenter, a neural speech gate, constrained decoding, and a word histogram, each catching what the others can't.
On-Device Meeting Transcription: The Whole Local Speech Stack
Every meeting recorder ships your audio to someone else's GPU. Here is the other architecture, stage by stage: AudioWorklet capture, a neural speech gate, Whisper in a worker, SQLite on OPFS, and a local LLM — with nothing crossing the network.
