Things you didn

From time to time, when I create a code, people ask me: Is this working? , or they tell me: I didn’t know that. Being in those situations allows me to understand that something normal for me can be new for someone else. So, today I would like to share with you some Ruby tips and tricks.

Ruby map(&:method) syntax - meaning & usage

Ruby map(&:method) syntax - meaning & usage

A few days ago, I worked on a customer project, and I wanted to use one line map but with an argument for a method inside this map. I never had this need before. Normally in one line map, I do something like .map(&:next). This time I needed something else. So, I did a short research on how can I do that. The results of this research were so interesting to me that I decided to create an article about this topic. So let’s get started!

Logitech G915 TKL with Ubuntu

I bought a Logitech G915 TKL keyboard at a beginning of the 2021 year. This keyboard works pretty well on Windows and Logitech G Hub software. There is a ton of ways to customize it. It can be fun.

Test doubles - the difference between stubs and mocks

In the testing world, we have stubs, mocks, dummy objects, and so on. It can be confusing what to use and when to use it. I would like to organize all of those terms in a more accessible way.

I don’t want to save those data in the git repository, but it is too early to put them in the database. In this case, environment variables can do the trick. You put sensitive data to the .env file, and you don’t track this file in the git repository. We’re done! Not exactly, in my case. I wanted to have the structured data in one file. So I used the environment variable together with YAML (recursive acronym...

How to focus as a programmer?

In times of full connections and online life, we have a problem staying focused. We need to focus, to feel the flow. One of the most important feelings in our work time.
