Erlang/OTP Supervision Trees: Choosing a Restart Strategy That Actually Fits Your Workers
How OTP supervisors restart failed workers: one_for_one vs one_for_all vs rest_for_one, a worked supervisor module with map child specs, intensity/period escalation, and the state-loss and crash-loop mistakes to avoid.
Detaspace Architecture: Isolation, Trust Boundaries, and Resilience
Detaspace partitions isolate data, enforce trust domains, and provide failure recovery. This guide outlines requirements, minimal design, boundary rules, operational checks, and failure modes to help architects decide when to adopt detaspace.

Supervision strategy is a claim about which Erlang processes depend on which. Pick it from the dependency graph, then confirm it with a deliberate kill on a test node.
erlangBuilding Fault‑Tolerant Concurrency with Erlang’s Lightweight Processes
Erlang’s lightweight processes enable millions of concurrent tasks with minimal memory. Learn how to build a fault‑tolerant counter server, watch it recover from crashes, and understand key trade‑offs like mailbox size, data copying, and supervision loops.
Turning Redis Streams into a Fault‑Tolerant Ingestion Engine for Real‑Time Analytics
Learn how Redis Streams and consumer groups can turn a simple key‑value store into a scalable, fault‑tolerant ingestion pipeline for real‑time analytics. See a concrete example, key trade‑offs, and actionable steps to get started.
