Το συγκεκριμένο post το έχω γράψει και σβήσει στο μυαλό μου αρκετές φορές να ξέρεις, τις πιο πολλές φορές ακόμα και η σκέψη για το θέμα μου έφερνε ένα κόμπο στην καρδιά και στο στομάχι. Τώρα δεν ξέρω πως θα μου βγει, αυτό το blog εδώ και μερικά χρόνια έχει χάσει λίγο το προσωπικό look and feel, αλλά είναι λογικό, …

Νομίζω ξεκινάει μια αρκετά καλή προσπάθεια στη Θεσ/νίκη, για τα ελληνικά πλαίσια αλλά και την τωρινή κατάσταση της ελληνικής αγοράς πληροφορικής. Ακούει στο όνομα DevIt conference, και έχει ομιλητές από διάφορα τεχνικά battle grounds. Παρά λίγο να βρισκόμουν και εγώ στη λίστα των ομιλητών, ίσως την επόμενη χρονιά. …

Series it's been a long time since my last post, for this series of tutorials. it's time to resume and add new features on our simple project.

Όπως όλοι οι Έλληνες λίγο πολύ, έτσι και εγώ είχα και έχω τις δικές μου πολιτικές εμμονές και ελπίδες. Με αυτές τις εκλογές, αυτή την εποχή, για μένα προσωπικά τελειώνει το κεφάλαιο της ελπίδας σε ότι έχει να κάνει με πράγματα που θα ήθελα να δω εγώ στη χώρα μου και στη διακυβέρνηση της.

Like many of you out there, I am working with a multi module Maven project. It is not a huge one comparing to many systems out there, it has 15 modules, with 3 different ear deployments, lots of parametrization with property files and around 100K lines of Java code.
