Git - basics

Git is a very important tool in a programmer toolbox. It is one of the version-control systems. Because git has a lot of very cool and useful features, it is also the most common one. I recommend you start learning git. So, to help you with that challenge, today we’ll focus on the basic git commands. This article is the second one in the git series. Last time, I talked about what is git? and why as programmers we should use it daily. Now, I will talk about: How to create the first git repository? How to configure git locally...

Lambdas in Ruby

I had situation where I worked with many different (but in some way similar) collections in Ruby. This collections had very similar methods to search elements by name. In this particular example I decided to use lambda. Let me show you how this looks like. Code which I get looks like this: do |activity| == 'name' end This is not bad code but in others places I had similar things. Collections (I mean arrays) and names were only changes. Like this: do |activity| == 'name1' || == 'name2' end So I decided to use lambda....

Coderetreat 2015 Cracow

Coderetreat 2015 Cracow

In last Saturday I was on Global Day of Coderetreat in Krakow. Coderetreat is one day in year when programmers focus not on delivery new functionality but focus on good code quality.

Be yourself – How deal with low self-confidence

Be who you are, say what you feel, those who mind don’t matter, those who matter don’t mind. Today I would write about very important for me topic. About self-confidence. I don’t know if you have some problems with it but I do. I went through this many times. And I went back to this topic because I change project at my work. About 4 weeks ago I started work on new project (for me of course, because rest of the team work on this project about 2 years). Project has very complex logic. On the beginning I felt like...
