Through versions, Rails integrated tools, enhanced performance, and adapted to industry standards, keeping a focus on developer happiness and efficiency. ActiveModel::Error is an example of that. On this blog post, we’ll dive into the evolution of this object.

As we mentioned many times, at FastRuby.io we like to use the Dual-Boot technique opens a new window during upgrades to quickly test the same code with the current and the next version of what we are upgrading. We usually talk about dual-booting Rails versions but this can be used to upgrade Ruby itself too. We have to make some changes to adapt the technique, and we’ll explain the basic changes in this article.

The Ruby community is special. It has an incredibly inclusive and supportive culture that feels different than other languages. It was great to take some time to come together and enjoy the community’s hard work, network, and plan for the future.

Here at FastRuby.io we always try to have our own applications in such a state that they can always be pointed to as models in terms of performance and accessibility.

One of the tools we use to achieve that is our CDN. After all, considering we have clients everywhere from the US to New Zealand, we want anyone perusing our websites to have good loading times for the pages and, especially, the assets.

However, no matter how thorough, one always misses a spot or two.
