Packages

A pure-Elixir TUI framework for Unix terminals. TEA-style model / update / view loop on top of OTP, with first-class focus traversal, layout constraints, ANSI cell-diff rendering, and a thin termios NIF for direct /dev/tty control.

Dedicated UDP socket source for phi_accrual. Escapes BEAM distribution head-of-line blocking. Receiver-driven clock discipline; packet timestamp is diagnostic-only.

Source-agnostic φ-accrual failure detector for Elixir/OTP. Observability-grade, telemetry-first, EWMA-based. Emits a continuous suspicion value per monitored node; thresholding and policy are consumer concerns.

Space-efficient distinct counting for the BEAM. Implements UltraLogLog (Ertl, VLDB 2024), a 2024 successor to HyperLogLog with 24–28% less memory at the same accuracy. Includes FGRA, MLE, and martingale estimators, CRDT merge, and bit-exact validation against the Hash4j Java reference.

Dedicated AMQP 0-9-1 consumer source for phi_accrual (RabbitMQ-class brokers; not AMQP 1.0). Treats broker deliveries as liveness signals; receiver-driven clock discipline. Envelope timestamp is diagnostic-only.
