New IntelliJ IDEA Tech Talk episode! Architecture as code. @rweisleder.de joins IntelliJ IDEA Tech Talks to turn architecture rules into ArchUnit tests, catch cycles before they catch you, and keep docs and code from drifting apart. 🔗 youtu.be/hEnSy8vlK10

Checking dependency upgrades is now a tool-tip away #DependencyAssistant 1.0 is GA now plugins.jetbrains.com/plugin/30958... #Maven #Gradle #NPM #GitHubActions

Slides should only support what you're saying, not replace it. You'll notice this, for example, when the audience points out that you haven't shared your screen yet... after 15 minutes.

TIL: Iconify - over 300,000 open source vector icons iconify.design

Just fixed a bug where Java's operator associativity actually mattered, hidden in some not-so-clean code. I guess it's time for a blog post...

Me traveling from DE 🇩🇪 into the NL 🇳🇱 bounded context. A domain event occurred.

OH "Ich bin im Unternehmen wie die Klobürste: für jeden Scheiß zuständig"

Today I installed Windows XP so I could install a program from a CD published in 1998. Being the badass that I am, I ignored the “optimized for Windows 95/98” part.

Ah, those cryptic tracking numbers again... #scammers

Sitting in a bus in Strasbourg when suddenly @kevlin.bsky.social enters

Today at the @lu.voxxeddays.com, talking about architecture and legacy systems

Days since last "@Data generates wrong equals method" incident: 0

Tonight at the @jugbb.bsky.social where @martinelli.ch talks about spec-driven development

Most teams already practice spec-driven development. Spec as in speculation.

github.com/rweisleder/a... has reached 100 stars on GitHub 🥳 Nice to know that it’s helpful to at least some people. And also a sign that it’s time to plan another release.

In today's episode of "tell me you don't understand agile without telling me you don't understand agile": "We canceled the Daily because the PO is on vacation."

Complexity is easy to add, but hard to remove.

Started the day fixing an N+1 problem. Turns out it’s a 4N+1 problem. Happy Monday.

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.

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

#JUnit 6.0.0 is released! ✨ Java 17 and Kotlin 2.2 baseline 🌄 JSpecify nullability annotations 🛫 Integrated JFR support 🚟 Kotlin suspend function support 🛑 Support for cancelling test execution ⏭️ New `--fail-fast` mode for ConsoleLauncher 🧹 Removal of deprecated APIs docs.junit.org/6.0.0/releas...

Honored to have been chosen as @sessionize.com Speaker of the Day!

Containers don’t save you from a distributed monolith.

OH: headless is overhead

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!"

Clean code starts with an appropriate data structure.

There's a great talk by @rweisleder.de abiut ArchUnit fyi

That moment 2 weeks before go-live when the client finally connects their frontend, built over 6 months, and the data model doesn’t match our API at all

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

*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".

OH: Comedy Admin (instead of Company Admin)

The reward for good work is more work.

OH: "andere Firmen haben auch schöne Software"

NullPointerExceptions are in fact just a love letter from Java to us developers. Brought to us by @intellijidea.com #Java30WithIntelliJIDEA

Fellow Java developers, if you're looking for a library or framework for your task, check out this repo: github.com/akullpp/awes... Looking at the diversity, you can already see that #Java is awesome!
