Hi! I'm Szymon

In this blog post, I show you how to build stackoverflow-cli - a command-line application that allows you to search Stack Overflow questions directly from the terminal window. I use Java 11+, Micronaut, Picocli, and GraalVM’s native-image.

In this blog post, I explain why you may want to use curl command in your Jenkinsfile, how to catch curl response and store it in a variable, as well as how to read HTTP response status code and extract some data from the JSON document. Enjoy!

Sticking to the process of achieving my goals has always been one of the most difficult obstacles to overcome, both on my way to becoming a better professional, and in my private life. I have found that in some areas I need to make an extraordinary amount of effort to keep myself on the right track, no matter how S.M.A.R.T. (Specific, Measurable, Achievable, Relevant, Time-based) my goals are. I couldn’t understand why in some cases I was able to make the desired progress, while in others I kept failing. Was it a matter of talent I was missing, or a skill I haven’t acquired yet? I have seen the dots, but I didn’t yet know how to connect them.

Have you ever wondered, what is the most convenient way to parse JSON data in the Unix/Linux command line? For instance, how to parse some information from the curl JSON response? Grep? No, thank you. There is a better tool for that. And it’s called jq.

The declarative Jenkins Pipeline allows us to define timeout either at the pipeline level or the specific stage. This feature prevents Jenkins’s job from getting stuck. However, in some cases, we want to accept that one stage may timeout, but we want to keep the remaining stages running.

Many content creators celebrate their 10k, 100k, or 1M subscribers/followers milestones. There is nothing wrong with that. Achieving such numbers require tons of work, time, effort, sometimes even luck. Those numbers do not show up overnight. People deserve celebrating those moments and sharing their happiness with their community. Today I want to share my own success with you. The number that wouldn’t be possible without your trust and support.

Dynamic type inference in Groovy might be tricky. Add generic type erasure to it, and you can find yourself in trouble. In this blog post, I would like to show you such use case and explain what happens under the hood. Enjoy reading!

Groovy 3 helps you write less, but more secure code. Today I want to show you one of the features added in the latest release - @NullCheck annotation.
