How ActiveRecord Uses Caching To Avoid Unnecessary Trips To The Database

ActiveRecord makes accessing your database easy, but it can also help make it faster by its intelligent use of caching. In this article, Jonathan Miles shows us the tricks that Rails uses to ensure that your database isn't doing more work than it needs to.

Building, Testing and Deploying AWS Lambda Functions in Ruby

For quick, scalable, highly-available web services, few options compare to AWS Lambda. Just provide your code, add a little configuration, and you're done! In this article, Milap Neupane will introduce us to Lambda, show us how to get it working with Ruby and the Serverless Framework, and discuss reasons to use — or to not use! — Lambda in production.

An Introduction to Go Tooling

In this article, Rupesh Mishra explains how instantiation, inheritance, and - yes - even metaclasses work in Python.

Exploring Merge Sort with Ruby

You'll probably never implement sorting from scratch. But sorting algorithms are foundational in computer science and have become a standard feature of the ritual hazing...er...interview process for developers at all levels. In this article, Julie Kent introduces us to the merge sort algorithm. She'll show us how it works, implement it in ruby, and discuss its performance characteristics.

Building a Programming Language in Ruby: The Parser

Understanding parsers is like seeing the matrix. You start to understand the tree-like structure of your code. You begin to realize that so many language features are just syntactic sugar concealing a simple core. In this article, Alex Braha Stoll will guide us through the world of parsers. He'll explain basic concepts, then use Ruby to implement a simple parser for his toy language, Stoffle.

Everything You Ever Wanted To Know About View Caching In Rails
