In many applications it’s a requirement to keep track of when a record was created and updated the last time. Often, this is implemented by having columns such as created_at and updated_at within each table. To make things as simple as possible for application developers, the database itself should take care of maintaining these values automatically when a record gets inserted or updated.

Imagine a city mayor considering a project offering to build parks in several neighborhoods. It can be a good budget investment since it can potentially increase the happiness level of the citizens. However, it is just a hypothesis: if parks do not impact happiness, it is worth considering other city renovation projects. It makes sense to perform a pilot experiment before spending the budget on all the parks. The mayor is thinking about the....

Java Foreign Function Interface (FFI) Evolved Binary has been working on several aspects of how the Java API to RocksDB can be improved. The recently introduced FFI features in Java provide significant opportunities for improving the API. We have investigated this through a prototype implementation.

Yesterday, I went on a hiking trip to Monte Tiravento. This majestic loop tour is uncommon compared to the classic woody image of the Parco Nazionale del Foreste Casentinesi, as it takes place mainly on aerial and partly even barren ridges, resulting in magnificent views. Compared to other variants I did in the past, this one starts at a high altitude, offering lower elevation differences. It is inadvisable on the hottest summer days when..

So if the goal is to replace the traditional search engine then we’re already failing. Because we’re not replacing anything, we’re just hiding it behind some AI tool. The second issu....

War Room is a board game by Larry Harris, the designer of Axis and Allies. I see it as at least a spiritual successor to AA, if not a complete overhaul. Like AA, it’s a grand strategy game set during World War II. Players control the major Axis and Allied powers and vie for the control of territories. The ultimate goals is to capture the opposing capitals and win the war. You can see my original Python notebooks on GitHub . I previousl....
