Spun up a clean AEM local today and wrote down the bits that keep my Maven and HTL setup neat and readable. Maven first, because future me likes boring builds When a project starts small and then grows new features each week, a tidy Maven reactor saves the day. The…

Java 10 brings var to local variables and it is already changing how my editor looks during code review. The new var keyword is short for local type inference. The compiler still knows the exact types and keeps all the strong guarantees we expect from Java. We just stop repeating…

Java 9 modules land with a simple promise: real fences for our code. If you have shipped large Java apps, you know the drill. The classpath is a mystery box, private stuff leaks out, and a tiny bump in a jar can wake the pager. Project Jigsaw has been years…

Dependency Injection Without Frameworks sounds like a dare, but it is really about writing code that reads like plain English and runs like a quiet engine. Every week I see someone reach for a giant container just to pass a couple of collaborators into a constructor. I get it. Angular…

Project Jigsaw is finally knocking on the door and everyone who writes Java is about to learn a new word: modules. For years the classpath has been our bag of tricks and pain. You dump jars in there and pray conflicts do not explode at runtime. It works until it…

I spent the evening shaving old code with fresh lambdas and it felt good. There is a special kind of joy in taking a brittle util class or a forest of anonymous classes and swapping them for clean lambda expressions. The code stops yelling and starts whispering. Today lambdas are…

Logging is that quiet teammate who remembers everything you forget in production. Why logging still wins If you build Java services for the web, logs are your second debugger. You can not attach a profiler to every box, and sometimes the bug shows up only under load or at three…

Null is boring, the crash at three in the morning is not, so lets keep null boring and safe with Optional. Swift just went open source a moment ago, Java 8 is now common on the server, Android builds are catching up, and Kotlin is knocking at the door with…

Streams are easy to read, tricky to test, and even trickier to trust without good tests. Every feed today chats about streams. Java 8 streams sit in most new code reviews, RxJava keeps popping up in talks, and Node 4 just landed with a comfy ES6 baseline that makes stream…

I keep coming back to the same thought when I sketch APIs on a napkin at a cafe: streams make code cleaner. We ship more JSON across the wire every week. We smash more collections into memory than we want to admit. The more I build services, the more I…
