Today’s Java is vastly different, although it is still true to its root principles of robustness, portability, and ease of programming. Your options for where to get your Java have similarly evolved. If you download Java directly, you might think that you can only get an official version from Oracle. This is no longer the case. In fact, there are …

Last year, I wrote my first yearly retrospective. I liked the experience, so I’m trying one more time. Let the future decide if it will become a trend or not. Before diving into our safe technological world, my thoughts go to Ukraine, to my friends who had to flee their own country, to other friends who fought on the front …
