I have organized my first free C# refactoring workshop. I called it From CHAOS to SOLID. The main idea of the workshop is to teach how the source code can be transformed in an easy way to be more maintainable and robust.

For the last few weeks, I have been learning docker. The start with new technologies was, as usual, easy for the basics and fairly difficult for the more advanced stuff. On some stage, I found KataCoda. The service motto is: Learn new technologies using real environments right in your browser.

Today I wanted to touch the subject of programming schools.

There are plenty of books about motivation. How to motivate yourself and others. We give ourselves something we like after finishing a difficult task. It can be a chocolate bar or an hour of video gaming. We try to motivate out employees with many benefits: free healthcare, informal Fridays, pizza days, in-house conferences etc. At the beginning it works quite fine, but as we go the effects are weaker and weaker.

Maintaining large software systems is hard. Such systems are usually complex by nature. On diagrams they look nice - couple figures exchanging messages each other. The devil is in details - as always. Microservices add extra complexity. We moved from monoliths to farms of services. Now we can deploy changes separately - we decoupled the responsibilities (SOLID rocks!). Now we have more nodes where out messages are flowing from and to.

In IT industry we have to learn quite intensive new things. Everything changes, but in our industry, it happens much faster. Today's buzzword is forgotten tomorrow. How do we approach that? 's annoying and silly to waste time on somethings like that.

Technical debt in software development is considered as implementing quick and dirty solutions in order to satisfy user (or deliver a sprint - Sic!). Those solutions should be paid-off in the future.

A while ago I wrote a post about [7 mental types of software developer]. Now it is time to the first adjustment. It turned out that "Code nazi" and "SOLID junkie" are pretty similar. Junkie was merged in to "Code nazi".

In every group of individuals, we can recognize a pattern. Observing and grouping people can give us more understanding of how teams are formed, how they work etc...

In the past, there were myths and legends passed between generations. Later Gutenberg introduced printing... the knowledge started to spread across the world rapidly. This day's books are the main sources of transferring knowledge. Open-minded people read a lot. I try to stay open-minded...
