4Developers Wroclaw - 2019

In 2019 I had an opportunity to be a speaker and participant on three local 4Deveopers events. In Krakow and in Katowice I was presenting my two speeches. I wrote about them an article Speaker at 4Developers 2019. One of my presentations you can watch on YouTube: Are you an Egoistic Programmer? - Step by step refactoring [PL]. The last event was in Wroclaw. This time I was a participant. It was a nice feeling to be there only as a participant. I could focus on conference its self without stressing out. How in few words I can describe 4Developers...

There it is! The Rails Girls Warsaw 2019 edition! Rails Girls workshops in Warsaw are one of my favorites in Poland. They are always close to my heart. First time I was a mentor at Rails Girls Warsaw in 2014. Now I go around Poland to share my programming knowledge. This time in Warsaw.

Local editions of 4Developers 2019

Local editions of 4Developers 2019

In one of my last articles I have written about my new challenge. To be a speaker at a conference. This happened two times at local editions of 4Developers in Krakow and in Katowice. It was for me interesting experience, especially that this audience doesn’t know Ruby as programming language too well. I had a chance to share my knowledge about Ruby and good programming practices with them. In the near future there are going to be two more local editions of 4Developers. And because of that I have a surprise for you which is prepared together with 4Developers organizers....

Iterators in Ruby

Ruby as other programming languages has many ways to repeat instructions. We can use loops for that. Loops like loop, while, until or even for. This is very useful, but Ruby has also something like iterators. Iterators are even more awesome than loops. In Ruby you have many iterators with some specific destiny. You can use each, map, collect, select, find, times or even more. But wait! When should I choose each and when should I choose map? This is a good question! And I’m going to answer it. Basic terms Before we start, let me explain you basic terms...

4Developers 2019

4Developers 2019

Normally I’m quite active in Rails Girls community. I’m a mentor and an organizer, and also a speaker at Rails Girls workshops. In this year is a little bit different. I spend less time supporting Rails Girls events, but I challenged myself in a different way. I started sending my proposals to the conferences. I wanted to be a speaker at more than just local community groups or Rails Girls events.

Functional programming in Ruby

Ruby is an object oriented language. That doesn’t mean we cannot do some functional programming in Ruby. When you take a look closer to the history of the Ruby language, you can find out, that Ruby was influenced by other languages like Perl, Smalltalk, Eiffel, Ada, Basic or Lisp. Because of this different inspirations we can find in Ruby not only object oriented concepts, but also a little bit of functional programming.

Ruby pattern matching

Some time ago I wrote an article about Pattern matching in Elixir. I really like this idea. Now from Ruby version 2.7 we have pattern matching in Ruby!!! It is not the same like in Elixir, but it is a nice feature to have. Keep in mind that this is still an experimental feature, so it can change in the future versions of Ruby. Let’s check out what we can do with pattern matching in Ruby.
