We all started at the same point - learning how to code. Most of us focused almost exclusively on learning how to program in a chosen language and practiced it. And there’s nothing wrong with that. It’s natural when you...

Recently we made an introduction to the Rails Event Store but to get fully into the topic there are dozens of ideas to learn about, so we won’t stop there. Today I would like to tackle the simplest problem in the stack...

Storing passwords is a pretty common workflow that needs to be done when developing web applications, so it's best to use well-established solutions for that.

Event store is a proper name for a..., well, storage of events. Events are facts from the past. Such a trait makes our storage a great candidate for append-only mode, ie. there are only two operations available: read...

Perhaps, bootcamps that you have experienced before were quite different than what we're doing. They may have cost you a lot of money and left you with a lot of theoretical knowledge but no real sense of what to do...

Over the past couple of years, we wrote extensively about Ruby (and Ruby on Rails), so you know we like it a lot. We’ve also dabbled some in Elixir (and Phoenix), but never before have we compared the two side by side...

Every year, we’re pelted by articles proclaiming the death of this gem of a framework. And while Ruby on Rails (RoR) is almost 15 years old, it’s nowhere close to passing on from the world of programming. 

To build a Web application that effortlessly serves your target audience, you have to make sure your chosen technology stack has the necessary capabilities.

So there you are: a backend developer with a few years’ experience in developing Ruby on Rails applications. Lucky for you, Ruby on Rails seems to be versatile enough to solve pretty much any problem you encountered...

I’m pretty much sure that sooner or later every developer finds themselves working on a project that makes them face the need to refactor legacy code. For those lucky ones who didn't experience it firsthand—legacy code...

Remember the story of tech leading a project in fours acts? It was a motivational (hopefully!) story about delivering a project and my experience with being a tech lead. It was focused around repositories helping us...

It happens in the lifecycle of every product—some dead or duplicated legacy code is slowing the project down, the team working on that particular product has changed, the technology and practices used have become...

Recently, I had a pleasure of attending the Wroclove.rb conference in Wrocław where one talk in particular caught my attention more than others. And not just because Ruby on Rails is my mother tongue. “Web Performance...

For a long time, I’ve been hearing a lot of criticism about the Rails way and some months ago my private experiences convinced me that I cannot find any use cases for that approach. It has developers build very fat...

Is there anyone out there in the Ruby community who doesn’t know Active Record? I don’t think so. Many of us start our adventure with Rails by writing AR models. And we write them a lot. We detect the N+1 issue many...

Recently, I’ve been playing around with a search in Elasticsearch and got stuck with development when attempting to work with an array of objects. Indexing went fine, the query results, however, did not look as expected.
