Handling InterruptedException in Java, so much fun 😐

Currently preparing a workshop for a client on how to become more productive with @intellijidea.com. Not something I expected to be asked for, but here we are.

Git graph showing a tangled mess of overlapping branches and merges, all created by a single developer in one day.

Thankfully, the project follows a strict branching strategy. Otherwise it would be pure chaos if a second developer worked on it today.

Gute Besserung!

Also a form of coupling, but at a very detailed level, right? What belongs together should stick together. What doesn't directly belong together should be separated from the rest.

Containers don’t save you from a distributed monolith.

OH: headless is overhead

Absolutely

Wait, did you skip the 80% of creating the demos?

Preparing a talk means spending 80% of the time thinking about what to talk about and the remaining 80% of the time creating the slides.

Our next #JCON2025 session is live: 'Unit Test Your #Java Architecture With #ArchUnit' with Roland Weisleder

#Architecture and #code are drifting more and more apart? The implementation of non-functional requirements and cross-cutting concerns…

Grab your coffee and hit play: youtu.be/MxP521_i9zM

#ChatGPT answering with "If you want I can..." and "Would you like me to..." is like an excited child saying "Look what I can do!"

And here I am, sitting on a friday afternoon, trying to fix an integration test that tests the interaction of mock objects based on false assumptions instead of testing the real system

Java code snippet with two fields: private Boolean optional = false; private @Nullable Boolean isMandatory = null;

*opens new Java legacy project*
*opens random POJO*
*sighs deeply*

Something that annoyed me when viewing test results in IntelliJ: it indeed shows the execution time for each test method, but not how long it took for example to start @SpringBootTest.

Today I discovered "Use Wall Time".

Would love to see that as a conference talk
