Java keeps evolving! Java 26 is out. The release brings many features aimed at optimizing Java applications and drops support for applets. We cover all of this and more below. Currently, Java ships a new version every six months. The last release was Java 25 in September 2025, so March 2026 meant it was time for Java 26.

A* looks simple until you implement it. Then one question appears: Why does this algorithm find good paths without checking every possible path? The answer is its scoring structure. A* does not only ask, “How far have I moved?” It also asks, “How far do I probably still need to go?” A* is a shortest-path search algorithm. But it is not blind search. It combines: the real cost so far the estimated

I recently read @raviteja_nekkalapu_'s excellent article "I built an AI security Firewall and made it open source because production apps were leaking SSNs to OpenAI" and it resonated deeply with challeng

So you've outgrown MySQL. Maybe you need better JSON support, real window functions, or you're moving to a managed cloud database that defaults to Postgres. Whatever the reason — MySQL to PostgreSQL migration trips up almost everyone the first time. The two dialects look similar but behave very differently under the hood. Why MySQL Dumps Don't Import Directly into PostgreSQL users ( id INT(11) NOT
