I’ve been using Capybara-WebKit for a long time, but, while switching from CircleCI 1.0 to CircleCI 2.0, I had some problems using it on the CI.
This triggered me to try Chrome Headless with Selenium Webdriver. I will show you how to configure Circle CI 2.0 and your Ruby on Rails project to use Capybara, Selenium, and Chrome headless together.
GitHub introduced their own CI server solution called GitHub Actions. You will learn how to set up your Ruby on Rails application on GitHub Actions with the YAML config file. To run your RSpec test suite faster, you will configure parallel jobs with matrix strategy on GitHub Actions.
GitHub Actions makes it easy to automate all your software workflows with world-class CI/CD. The building, testing, and deploying your code right from GitHub became available with simple YAML configuration.
When working on a larger project, you may struggle with the problem of an increasingly growing set of tests, which over time begins to perform slower on your continuous integration (CI) server. I had this problem while working on a project in Ruby on Rails, where RSpec tests on CircleCI took about 15 minutes.
As it was bothering me, I decided to do something about it, which resulted in building an open-source Knapsack Ruby gem library (the name derives from the knapsack problem), which deals with distributing tests between parallel CI servers. In this article, you will learn about two approaches to split tests on parallel continuous integration servers - static and dynamic.
Rails version 1.0 is approaching its 15 year anniversary, and there’s reason to celebrate the framework's progress.
There have been hundreds of amazing products built with Rails since its creation.
As a developer, you will be seeing numerous articles on Big Data, containers, complex algorithms, caching, etc. But the reality is that a lot of us still have to solve simple problems, especially if one is a freelance programmer or working with small companies.
A simple use case is that of data, coming in spreadsheets or CSV files, have to be visualized in a simple dashboard. You and the customer agree to build it as a web application. There are plentiful ways, from PHP to the Java-based Metabase, of implementing the solution. Since I have experience with Ruby on Rails (RoR or just Rails) and it has extensive easy-to-use libraries, it's my first go-to choice to build a web application real quick.

Hey!
This is the blog post version of the Youtube video of the Ruby Coding Challenges in 30 days.
Hey folks!
In today’s post, which is the written version of the Youtube video, we’ll rewrite the previous algorithm with a little bit better version. It’ll be really quick, I promise.
Hey folks!
In today’s post, which is the written version of the Youtube video, we’ll explore how to calculate Factorial Numbers in Ruby. I know that you have heard about that before, but just a refresh:

Given the popularity of our post on connecting MongoDB SSL with Self-Signed Certificates in Node.js, we decided to write a tutorial on connecting MongoDB with Ruby. In this article, we’ll show you how to connect to a MongoDB server configured with self-signed certificates for SSL using both the Ruby MongoDB driver and the popular Object-Document-Mapper (ODM) mongoid.
ScaleGrid currently uses self-signed certificates for SSL when creating nodes for a new cluster. Additionally, we also provide you with the option of purchasing your own SSL certificates and configuring them on the MongoDB server, and you can email to learn more about this offer.
The CData ODBC Driver for Cloudant makes it easy to integrate connectivity to live Cloudant data in Ruby. This article shows how to create a simple Ruby app that connects to Cloudant data, executes a query, and displays the results.
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
