elixirManaging Process State in Elixir with GenServer: Calls vs. Casts
Learn how to manage process state in Elixir using GenServer, including the critical technical differences between synchronous calls and asynchronous casts to avoid timeouts and mailbox overflows.
Implementing a Gen Server and Supervision Tree in Gleam with gleam_otp
Learn how to use gleam_otp to implement Erlang gen_server behaviours and supervision trees in Gleam, with concrete build and verification steps for the Erlang target.
gleamElixir Supervisor Restart Strategy Diagnostic Guide: Recognize, Check, Fix, Escalate
Frequent `:shutdown` messages and CPU spikes signal rapid child restarts; this guide shows how to diagnose and fix Supervisor restart strategy issues in Elixir.
Performing a Zero‑Downtime Hot Code Upgrade in Erlang/OTP with Release Handler
Learn how to update an Erlang/OTP application on a live node using release_handler, appup files, and OTP’s built‑in rollback. Follow a step‑by‑step guide, verify the upgrade, and recover if something goes wrong.
erlangManaging Volatile State in Elixir: Beyond Simple GenServers
GenServer isolates state in a single process, but that state vanishes on crash. Learn the API-callback split, a working counter example, and how to monitor mailbox bottlenecks before they stall your system.
Choosing Erlang’s one_for_one Supervision Strategy for Fault‑Tolerant Services
Learn how the one_for_one restart strategy isolates failures in Erlang OTP supervision trees, see a concrete gen_server example, and understand when to use it.
