In this post, we’ll look into tried and true methods of improving Rails view performance. Specifically, I will focus on database efficiency, view manipulation, and caching. I think the phrase “premature optimization is the root of all evil” has been taken a little out of context. I’ve often heard developers use this during code reviews when simple optimization techniques are pointed out.

In today’s post, we’ll cover the significant differences and benefits of using structure.sql versus the default schema.rb schema formats in your Ruby on Rails application. In a data-driven world, knowing how to exploit all of your database’s rich features can make the difference between a successful and unsuccessful enterprise.

Hi there stroopwafel fans As we’re looking forward to publishing more Ruby, Elixir, and JavaScript posts in the coming 2020, we decided to take a look back at the blog posts that you gave the most hearts on Twitter, reads on the blog, and that we got the most appreciation for in 2019.

In today’s post, we will be covering the Elixir library named Broadway. This library is maintained by the kind folks at Plataformatec and allows us to create highly concurrent data processing pipelines with relative ease. After an overview of how Broadway works and when to use it, we’ll dive into a sample project where we’ll leverage Broadway to fetch temperature data from https://openweathermap.org/ in order to find the coldest city on earth.

In this post, we’ll explore how to create Ruby modules that are configurable by users of our code — a pattern that allows gem authors to add more flexibility to their libraries. Most Ruby developers are familiar with using modules to share behavior. After all, this is one of their main use cases, according to the documentation.

Hello again! Welcome to the finalé of a two-part series of posts on errors in JavaScript. Last time, we took a look into the history of errors in JavaScript — how JavaScript shipped without runtime exceptions, how error handling mechanisms were later added both to the fledgeling web browsers of the day and to the ECMAScript spec, and how they future efforts to standardise these features would be connected to the politics of the browser wars of the late 90’s and 2000’s.

In this post, you’ll learn how to use ETS as a caching mechanism in your Elixir applications, get familiar with different available options, and be made aware of some things to keep in mind.

In this post, you’ll learn which metrics to keep an eye on to improve your application performance, how AppSignal works, and how to interpret the data it generates. Grab a stroopwafel, make yourself comfy, and let’s start!

We often get questions about optimizing or monitoring Sidekiq. Monitoring is kind of our game, but optimizing Sidekiq’s performance is a different ball game altogether. In reality, optimizing is complex, but let’s start by looking at the seemingly simple answers…
