Jenkins is one of the earliest and still one of the most-used continuous integration and continuous delivery (CICD) servers. It has lots of competition these days, but still has a robust community and a wide range of plugins (1,400 when I last checked). Even if you wind up using a different automation server, it is worth understanding how to use Jenkins: The underlying concepts of CICD don’t change much from one implementation to another, even though the vendors do tend … Read the rest

PostgreSQL (aka Postgres) is old as dirt, yet over the past five years it has panned out as pure gold. MongoDB got the billion-dollar IPO and AWS launched the mind-bendingly cool Aurora Serverless, but it’s PostgreSQL that keeps having its moment—again and again and again.
