In the IT world the idea of a hackathon is widely known and very popular. This is a very good opportunity to test your programming skills, free up creative resources and test your presentation skills. So when we got the invitation from Sandoz, one of the world’s largest drug manufacturers, we didn’t hesitate for a moment. We knew we would be there. And we were. What’s more, we brought one out of the three awards with us! How did this happen? You must read on.

Machine Learning is slowly becoming synonymous with Artificial Intelligence, and around the mysterious name of Data Science accumulated so many myths that it has lost its original meaning long ago. Personally, I consider myself more of a mathematician rather than a programmer because of my mathematical background, which in turn is not so rare among Data Scientists. It will not surprise anyone that I like to use terms that are ordered within a certain system. Therefore, let’s have a look at the AI ecosystem together to introduce some order.

Sometimes constantly improving and updating old software is as demanding as preparing a new solution from scratch. Considering that there are pros and cons to both approaches, the best way may be to combine both methods and create a hybrid software. Though creating a hybrid software is not alchemy. To clarify, the result may well be the philosopher’s stone of business software.

In our company teams are practicing Scrum. In this article, you can find a simple explanation on how we perform backlog items estimation.

As a rule, it looks like most of us don’t think about how to build a development team. The team is just there. There are several developers, sometimes a tester and they form a team… only in name. However, are these people really a team? Real teamwork is really a fleeting matter. Unfortunately, organizations often fall into traps that don’t allow them to achieve teamwork within their dev teams. How to get out of the impasse? Read below.

Some may ask: what is the point in doing code review if we have automated tests? Let me ask differently…what exactly do tests test? Is the app correct? Or whether the app has errors? My answer is: tests can only help us know if the app has errors. Tests alone, don’t care about the quality of the code.

I have already written about the art of communication with business here. However, the ability to communicate is one of the basic skills of the system architects. Actually, how else can you make a good system without prior, good understanding?

System architect is a person who misses the code. Ha! Surprised? I don’t think so. If you are an architect like me, you probably feel this longing. Smaller or larger, but somewhere subcutaneously, admit it, you miss coding, don’t you?

As a QA, I have to admit the last day at work before holidays is a disaster. But it is not as bad as when I am sick and I’m not able to work at all for a few days. And that is a complete catastrophe! Is there any way to deal with QA absence?

As software developers, we write code which falls into one of two categories. The first one is the business logic code – the essence of the software we create. The second one is infrastructure code – a backbone of the application. Did you ever think what is the optimal ratio between an amount of code in these two categories? In this article, I will share my observations on this topic. Small side note, in the course of this article I will use term BICR to denote Business/Infrastructure Code Ratio.
