Understanding a fundamental Ruby abstraction for concurrency etc.

This article was originally published by Ross Kaffenberger on his personal site, and with his permission, we’re sharing it here for Codeship readers. One of the fundamental concepts in key Ruby libraries that embrace concurrency is the thread pool. You can find examples of thread pool implementations in gems like puma, concurrent-ruby, celluloid, pmap, parallel, […]

Capybara, aside from being the largest rodent in the world, is also a fantastic tool to aid you in interacting with browser functionality in your code, either for testing or just to interact with or scrape data from a website. Capybara isn’t what actually interacts with the website — rather, it’s a layer that sits […]

Learn the essentials of cache expiration in Rails, and see how fundamental cache key composition is to a performant cache.

On RubyTapas, I occasionally need to demonstrate web application code. I often use little Sinatra apps for this purpose, because it allows me to illustrate a web app programming concept with all the usual features like routing, sessions, and templates without switching between lots of different files. When I do this, I also like the […]

With very little effort, you can tap into Postgres' native full-text search functionality with PgSearch. PgSearch also exposes a number of options/configurations that allow you to tweak how full-text search happens inside Postgres. Alright, let's do it!
