B-trees and database indexes — PlanetScale

Link: B-trees and database indexes — PlanetScale: "B-trees are used by many modern DBMSs. Learn how they work, how databases use them, and how your choice of primary key can affect index performance."

Linked is a neat article explaining a lot about b-trees. Especially notable are the excellent visualization and animations which gave me a new way to understand these incredibly important data structures.

The Thread API : Concurrent, colorless Ruby

Link: The Thread API : Concurrent, colorless Ruby: "👋🏼 This is part of series on concurrency, parallelism and asynchronous programming in Ruby. It’s a deep dive, so it’s divided into 12 main parts: Your Ruby programs are always multi-threaded: Part 1 Your Ruby programs are always multi-threaded: Part 2 Consistent, request-local state Ruby methods are colorless The Thread API: Concurrent, colorless Ruby Interrupting Threads: Concurrent, colorless Ruby Thread and its MaNy friends: Concurrent, colorless Ruby Fibers: Concurrent, colorless Ruby Processes, Ractors and alternative runtimes: Parallel Ruby Scaling concurrency: Streaming Ruby Abstracted, concurrent Ruby Closing thoughts, kicking the tires and tangents How I dive into CRuby concurrency You’re reading “The Thread API: Concurrent, colorless Ruby”."

Linked is a really excellent, comprehensive tour of the Thread class and feature of Ruby. If you're a ruby person, then this is as good as anything you will find.
