Note: if you are looking for an all-around guide to set up your environment, have a look here. Yet again, a small tip towards configuring your Java development environment on a Mac (OSX 10.8.x+). If you are really starting right now, I recommend you read one of my previous posts, a quick and clean (I suppose) way to …

This post mostly serves (as many others) as a technical note to myself for future reference. I am not an Oracle DB Administrator nor do I plan to become one in the future. As a software engineer I am required (like many of you), from time to time to interact or administer at some level the underlying RDBMS. In general, …

For the last 3 weeks or so, I have been using BitBucket to privately host one of my late night coding experiments, along with my friend and co-jug leader Panos. It is a private git/mercurial repository service and it's been around for a while, it is also free to use with a limit of 5 user accounts per repository. The …

Another quick late night Eclipse test hack I guess. Well it is the Java application that I use the most, meaning at least 9-10 hours per day.

For various reasons and mostly simplicity, in terms of moving straight away from the model of keeping my own SQL statements and applying them manually,to the context of Liquibase and it's automation, I have been using the formated sql changeset/log …

I am not a huge fan of DB specific and DB oriented development. For years now I have been participating in projects using different systems like MySQL, Ingress, SQLServer and of course Oracle. The last one one (Oracle) seems to be dominating in these recent years in most of the projects I _ve seen. When it comes to …

This is one of these posts, for me as I call them. A log of helpfull tips during work that might prove handy in the future.
