Opal – Ruby on JavaScript VM – What’s Still Missing

JavaScript VMs are everywhere, and environments running them such as browsers and phones look likely to remain the dominant way for users to interact with software for a very long time. This led to an explosion in the popularity of JavaScript – the native language of that environment.
But JavaScript is a dreadful language. It started a dirty hack, which just so happened to be positioned right and benefited from browsers becoming the universal user interface. It can’t even ever get properly fixed like, let’s say, Python 1, due to unique backward compatibility cost.

RSpec Rails Controller Test

Rails is a web development framework, where model, view, and controller are important aspects of your application. Controllers, just like models and viewers, need to be tested with the Ruby community’s favorite tool, RSpec.
Controllers in Rails accept HTTP requests as their input and deliver back and HTTP response as an output.

Pipelines on a Rails Environment With react_on_rails and Webpack

I noticed a bit of a gap when it comes to documentation and setting up Bitbucket Pipelines when you have some modern webpack dependencies with yarn.
If you’ve gone through this process, you may have struggled to find helpful documentation, too. I thought it may be useful to walk through some of the basics of how Bitbucket Pipelines is set up and strategies to help debug your pipeline’s configuration. Read on for my experience of going through the process of setting up Bitbucket Pipelines on a Rails 5.2 environment.

Ruby vs Golang: Which Is the Best Solution?

The fast growth of software applications is not a question of popularity alone, but a real opportunity to profoundly improve the business process of any industry. Get ahead right away by choosing the perfect programming stack that you will use while creating an excellent software solution. Below, we compare Golang vs Ruby, two of the most notable programming languages of recent years.
Ruby vs Golang: Performance
The key principles of Golang development are simplicity and productivity. Go is very fast to learn, easily readable by developers, and has a simple, intuitive syntax. Rob Pike, one of the leading authors of Go, assures that the language was specially created to simplify the development process and to achieve results faster.
