Lately I try to level up my skills with Kotlin, mostly from the view point of a JVM backend developer. I really feel very motivated and enthusiastic, I think the language has the right balance to make me feel like home (I am a hardcore Java developer after all) but at the same time give me new skills. As I've said …

Today we spent half a day, on our first HackTheTower event. Members of London's Java User Group (aka LJC), gathered on the 26th floor of SalesForceTower (aka Heron Tower) at the City of London, invited by: Heather VanCura Mani Sarkar Simon Maple to talk and learn about one Project Jigsaw, Java 9's modular-isation …

I guess lots of people will have something similar, I thought to share my small customized container. So here, you can find a small Alpine Based container, stuffed with bash curl envsubst kubectl helm (client) It is mostly used as a _gitlab runner, in order to _talk to kubernetes clusters (injected with the appropriate …

I am thinking (or maybe I can see), that while more companies jump to the cloud, migrating their existing software solutions and services, things like tech-debt or architectural-debt are going to become a first class citizen and hot topic, again. Which is a good thing! Really! I am very happy about it, because I do …

The original author, had created a very elegant way …

One of the projects I follow lately, is Wildfly Swarm. Eventually my request during this year's Devoxx in the JBoss BOF, to consider changing the name of the project, did not go through (due to the conflict with the famous Docker Swarm). So what is Wildfly Swarm? Simply put, is the Wildfly application server (app …

Well I needed to kill some time during this strange intermission period between jobs. My original 1-hour hack (less than 100 lines of code), evolved to something more flexible and useful (I hope so). Eventually my father is very happy now, instead of 1 newspaper summary he now receives He was also kind enough, to email …

Recently I stumbled upon several articles and examples of this handy library called JSoup, and I wanted to give it a try. It was a good opportunity to play and experiment around with CSS Selectors. My main need was a family request. My father is a captain for the trade navy. He still travels around the oceans in big …

I am new to Vert.x but as a Java developer (die hard) I find it much more enjoyable and promising comparing to NodeJS or whatever - Reactor based frameworks/libraries. So I was going through implementing a very simple Restful API, using Vert.x. My problem for today is that I wanted to include some certain HttpHeaders …
