Astrology chart calculation in pure Ruby: apparent planetary longitudes (VSOP87D, ELP-2000/82B moon, Meeus Pluto), Placidus and whole-sign houses, retrograde flags, aspects, derived points (Part of Fortune, mean Lilith), aspect-pattern detection and element statistics, plus synastry, transits, secondary progressions, composite charts and solar returns. No C extension, no external data files. Implemented from public formulas (Meeus, Astronomical Algorithms 2nd ed.).

Astrolith is a decoupled astrological data calculation engine that generates structured JSON output. It supports multiple chart types including Natal, Solar Return, Progressed, Composite, and Transit charts.

An Async AWS SDK adapter for `socketry/async` framework

A production-grade lightweight background job scheduler built on the Fiber::Scheduler interface itself, not on any one implementation: it runs under Async/Falcon, Itsi, or anything else that installs a scheduler. Single event loop with min-heap timer, skip-overlapping execution, jitter, monotonic clock intervals, semaphore concurrency control, and deterministic worker sharding.

Pattern and library for implementing asynchronous caching

With EventEmitter you can build your application in Event-Driven way. It acts as global pub/sub mechanism and uses Sidekiq to reliably and asynchronously deliver messages to subscribers. Using this approach you can enforce low coupling between different components of the system.
