Designing a Minimal OTP Supervision Tree for Fault‑Tolerant Erlang Services
Learn how to build a minimal OTP supervision tree in Erlang: requirements, design, trust boundaries, operational checks, failure modes, and when to redesign.
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.
Building a Fault‑Tolerant Erlang Service with a Simple OTP Supervision Tree
A concise architecture note that outlines requirements, the minimal supervision‑tree design, trust boundaries, operational checks, failure modes, and triggers for redesign when using Erlang/OTP for resilient services.
erlangErlang Supervision Strategies: Choosing one_for_one or rest_for_one by Dependency
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.
Designing a Stateful Worker in Elixir: When One GenServer Is the Right Answer
An architecture note on using a single supervised GenServer for serialized state in Elixir: requirements, a minimal implementation, trust boundaries, production checks, and the conditions that should push you to ETS, sharding, or distribution.
Implementing Passwordless Login with Supabase Magic Links
Eliminate password friction by implementing Supabase Magic Links. Learn how to set up passwordless OTP authentication, handle redirects, and secure your flow against phishing.

A technical decision guide for Erlang/OTP state management, comparing ETS, persistent_term, and the process dictionary based on latency, concurrency, and mutability.
GenServer in Practice: Managing Concurrent State in Elixir Without Locks
GenServer serializes access to state without locks. This post builds a working key-value store, puts it under supervision, and explains when a single process becomes the bottleneck.
