In article How to change parent branch in git? I talked quickly about using git rebase --onto in a case when you want to replace the current parent branch. But git rebase --onto is more than just replacing parent branch. We can do much more with git rebase --onto help. It’s a good topic to take a look closely. To use it freely first, you need to understand it.
A few days ago, I created new branch. I did some commits there, but after a while I noticed, that I created this new branch from the wrong parent branch. I created it from some feature branch not from the master. What I should do in this situation? I need to merge my current branch before I will merge this other feature branch and I don’t want to add not needed commits to mater branch. How can I handle it? Well, here is the time for git.
When it comes to programming I always think about the quality. And when we talk about quality, we need to mention testing. Testing software is very important. This is for me so natural, so transparent that almost obvious. I realized that this isn’t obvious to everyone on one of my presentations. I asked the audience about testing and I have already known, that I need to talk about testing more. When I write a code, I also write tests, but I do that in reverse order. First, I write a test, then the code. This are for me two elements...
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.

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.
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....
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...
