Its been some weeks now that our migration to Amazon EKS (work place) is completed and the clusters are in production. I have written a brief in the past on some major points, you can find it here. With some extra confidence while the system is serving real traffic I decided to come back for a more concrete and thorough ...

Yesterday I had the pleasure to attend the very first Voxxed Days Athens. As I have written 6 months ago while attending Voxxed Days Thesalloniki, this was the day I’ve waiting for too many years, a  proper conference, with top class speakers on the main IT hub of Greece, Athens. Once again, congrats to Patroklos Papapetrou and the team around Voxxed Athens, at ...

Yesterday at the Java9, Jigsaw HackTheTower event, I realized that I need to step up my game and improve my existing mechanism on maintaining several different JDK’s on my machines. I used to manually download the jdk’s, or install them using brew cask, and I would set ‘bash alias’ on my `~/bash_profile` to switch between different ‘ JAVA_HOME‘ etc etc. I am ...

I always enjoyed sharing knowledge. One of the reasons I blog is to share my knowledge on things around my job as a software engineer. Founding and running (with a handful of friends) the first Java User Group in Greece back in 2003, was due to the fact that we could not get sufficient training or access to personal development ...

I still remain skeptic towards Spring, of course there are some very nice ideas, there are some nice (too many) abstractions, there are some very handy ‘shortcuts’ ...

In the project which I recently joined, I discovered a set of annotations, (part of the code) that eventually did not add any functionality but they were ‘marking’ classes or fields  as a potential bad implementation, or as a potential case that may need to be reworked. The original author, had created a very elegant way (imho) on annotating parts ...

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).

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 in most (all) of my ...
