Coming back to Java from C# and @jetbrains Rider, I missed having warnings for explicit types instead of var. Since IntelliJ lacks this feature, I built a small plugin that detects and fixes it. You can Check it out here: github.com/KalbarczykDev/…
Unpopular opinion: Software engineering is the only job where the interview is harder than the actual job Interview: Design a distributed system for 10M users Job: The login button moved 2 pixels, please fix
Do you still write imperative code when working with collections that looks like it was written before Java 8? Embrace functional programming in Java. Check out my recent video about Streams: youtube.com/watch?v=pa_3nK… #java #java8 #programming #functionalprogramming
Had the chance to join the AI Summit PJATK 2025 🎉 Hosted at my school (@polskojaponska ), it was super inspiring & gave me fresh perspective on AI in business. Also… gotta say, loved the swag bag 📷 #AI #Conference #AISummit #PJATK
One day you're young, the next you're watching a Java launch stream.
Funny observation I had recently: I’ve seen more people debunking the ‘Java is dead’ claim than people actually saying it. Does anyone in 2025 still believe that Java is going away anytime soon? #Java #Programming #SoftwareDevelopment #Developers #Coding #Tech
i never saw this coming
🍃 Spring Boot Tips #4 🚀 3 ways to map inheritance with Spring Boot Data JPA: 1️⃣ Table Per Class: each class its own table, parent few fields, children many 👩🎓👨🏫 2️⃣ Joined: shared parent table, children reference by ID ✅ 3️⃣ Single Table: one table + type column ⚡
Language verbosity is a blessing in disguise. While some devs may not like it when writing a solution, you'll surely appreciate it when reading someone else's code. In non-trivial software projects, development is more about reading than writing.
🍃Spring Boot Tips #3🚀 toList() vs Collectors.toList() in Java Both produce a list from Stream, but they are not exactly the same. Collectors.toList() → returns a modifiable list ✅ toList() → returns an unmodifiable list ❌ (add/remove = UnsupportedOperationException)
