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.
A Native macOS App Without Xcode: Makefile, AppKit and a Slack-Style Room
Shipping a real Mac app with nothing but clang++ and a Makefile: a hand-built .app bundle, an icon the app draws itself, what ad-hoc signing costs you, a Slack-style chat room in plain AppKit, and why the notifications that looked broken were being eaten by Focus.
WebSockets From C++ on macOS That Survive Sleep, Wi-Fi Drops and Restarts
A laptop is a hostile place for a long-lived socket. How a C++ desktop chat app wraps NSURLSessionWebSocketTask in a small state machine: pings and a stall watchdog, backoff that resets at the right moment, stale-callback guards, close codes that mean stop, and a reconnect the instant the lid opens.
A Dependency-Free C++17 Core for a Desktop Chat App
The model behind a native chat app, in portable C++17 with no packages: a 300-line JSON parser that degrades instead of throwing, one apply() function that turns every server frame into an event, and unread rules that know a launch from a reconnect.
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.
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.
