The goal here is to demonstrate how true parallelism can be achieved with global mutable state (which at the time of writing, is not supported by built-in Ruby primitives). Familiarity with Ruby, Rust, C, (and a bit of other tooling) is nice to have, but hopefully not mandatory. The repository with code examples can be fo

  This article was discussed on Hacker News. While considering concurrent queue design I came up with a generic, lock-free queue that fits in a 32-bit integer. The queue is “generic” in that a single implementation supports elements of any arbitrary type, despite an implementation in C. It’s lock-free in that there is guaranteed system-wide progress. It can store up to 32,767 elements at a time — mo

One of these is controlling the load on the origin servers. Usually, most systems are designed with a centralized origin service that is responsible for producing the required content for the CDN to pull and cache. This works great when the content ca
