cloudrunUsing Swift Actors to Protect Shared State in Asynchronous Code
Learn how Swift actors eliminate data races by isolating mutable state, see a concrete counter example, and understand the reentrancy trade‑off.
swiftCloud Run Concurrency: Why the Default of 80 Is Probably Wrong for Your Service
Cloud Run's default container concurrency of 80 is great for I/O-bound services and quietly terrible for CPU-bound ones. Here's how to find the right value with a simple stepped load test — and what it costs you.
Shared Mutable State in Rust with Arc<Mutex<T>>: A Practical Guide
Arc<Mutex<T>> is Rust's idiomatic answer to shared mutable state across threads. Here's how the guard-and-poisoning mechanics work, a runnable counter example, and when atomics, RwLock, or channels are the better call.
rustDiagnosing Memory Ordering Bugs when Porting to ARM64
Learn how to diagnose and fix subtle multithreading bugs when porting code from x86-64 to ARM64, focusing on the transition from a strong to a weak memory model.
aarch64Designing 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.
Building 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.
Fetching Many Things at Once in F#: Async Workflows Without the Threading Headaches
F# async workflows make concurrent I/O-bound work simple with async { } and Async.Parallel — if you avoid the blocking-call trap that starves the thread pool.
dotnetFrom Callbacks to Structured Concurrency: A Practical Guide for Swift 5.5+
Callbacks and GCD can hide bugs and leak work. Swift 5.5+ structured concurrency—async/await, TaskGroup, and actors—offers a compile-time-safe replacement. This guide covers wrapping callbacks, parallel fan-out, actor isolation, and migration steps.
