Demystifying Dependency Injection - What It Is and Why It Matters Most projects use Dependency Injection in some form. However, many developers take it for granted and do not really question what it is or why they are using it in the first place. This article aims t...

Last year I gave the talk "Demystifying Dependency Injection" at a few #Java conferences and Meetups ( #JconSlovenia, @javaforumnord.bsky.social, #JavaCro, @jugmuenster.bsky.social , @openvalue.eu ). I am now breaking that talk up into a series of articles.

Though I am home for a few weeks now and the daily grind has caught up, looking back to #JavaCro is still putting a big smile on my face.

A really well run conference with inspiring talks in a unique location: an island before Rovinj.

Hashtag Jakarta EE #303 Welcome to issue number three hundred and three of Hashtag Jakarta EE! This week I was in Croatia for JavaCro 2025. The conference season isn't quite over yet. Next week, I will go to Kraków to present Jakarta EE at JDD 2025. Last time I was at JDD was in 2014, so It has been a while since I spoke at this conference.

Hashtag Jakarta EE number 303 is out!

JavaCro 2025 My first time at JavaCro was a vert pleasant ecperience. I have heard so much about this conference located on an Island off the shore of Croatia. The Island is Sveti Andrija (St. Andrew Island), a 15-minute boat trip from Rovinj. I had two talks on the first day of the conference. The day started with Tanja's talk titled Jakarta EE impact on the Java ecosystem.

All you need is fast feedback loop, fast feedback loop, fast feedback loop is all you need (JavaCro '25) Have you ever been on a project where desperation can get the better of you? It was more of an odyssey to get a change working in a real environment... in less than 1 or 2 hours? Or where to do a…
