Sometimes it happens. You stumble upon something that feels brand new to you — only to find out it’s been around for years. When I joined Moderne and started working with its OpenRewrite framework, this exact thing happened. I discovered the Java Service Provider Interface (SPI), a native mechanism in Java that enables plugin-like extensibility in applications.
It’s the year 2023. JDriven colleagues have gathered to discuss the new trends and deprecations of our work to put on the latest TechRadar. Once everybody is seated, everyone contributes their latest opinions. Very soon discussions run high. Lombok is dropped at the table of discussion as well. After some debate, it is decided. Lombok is put on HOLD!
False expectations take away joy, according to Sandra Bullock. Such was my feeling when I tried to write a full-fledged document using AsciiDoc. I thought I would be a pleasant journey. Could I be wrong?
Sometimes the answer to your problems is right in front of you. But somehow you just can’t grasp it until you’ve had a bit of an enlightenment experience. This happened to me a couple of weeks ago.
You never touched Groovy, nor did you jump on the Scala train. Clojure never attracted you; and you heard about Ceylon long after the language had already died. You are one of those old-fashioned Java folks! But now, after all those years, you want to join the cool Kotlin kids. So, where to start? Let’s discover the language together by decompiling it to Java code. Today: The things we tend to forget!
Dear Diary,
"Hobbits really are amazing creatures. You can learn all that there is to know about their ways in a month, and yet after a hundred years they can still surprise you"[1]. The astonishment Gandalf experiences, that you know something very well but somehow overlooked it, is not unfamiliar to me. Well, let me tell you a story…
Dear Emily,
You know that feeling when it suddenly clicks? Something you never knew or could not understand. And then, boom, this new knowledge is there for the taking. Well, I had this experience some time ago.
You can tell your old man
You’ll do some largemouth fishing another time
You just got too much on your plate to bait and cast a line
You can always put a rain check in his hand
'Til you can’t
