Femtoblogger now sends IndexNow notifications for new and updated posts, using a key-backed verification file to prove site ownership without account management.

A real-world Lua policy manages dual-voltage battery banks, solar, generators, relays, and inverter interlocks—plus a practical workflow for staging configurations, flashing firmware, and inspecting controller snapshots with `power4ctl`.

A Swift Concurrency–friendly SQLite layer offers actor-owned connections, explicit read/write transactions, prepared statements, and typed row decoding—without an ORM, query builder, or migration framework.

A USB serial tool polls SRNE-based inverter registers via Modbus, emits periodic or one-shot JSON, and can toggle power-saver mode for basic automation.

blescan uses Rust, zbus, and BlueZ’s D-Bus APIs to list nearby advertisers or inspect a device’s GATT services, characteristics, and readable values. Prebuilt Debian packages are available for Raspberry Pi.

Reverse-engineering undocumented BLE characteristics and avoiding BlueZ/NimBLE connection traps made remote battery telemetry possible—until a stuck client silently removes a pack from advertising for hours.

Cassandra’s Deal eliminates its “Settings” screen and makes for a less stressful app experience.

Cassandra’s Deal uses real-time solvability analysis to flag the move that ruins a winnable Klondike hand—while its creation exposes where AI coding agents excel and where platform expertise still matters.

Keep Ethernet as the active connection while macOS scans nearby Wi‑Fi beacons for geolocation. Disabling Auto Join on saved networks prevents unwanted wireless failover without sacrificing Location Services.
