The way it works is you load in some JavaScript (typically from a third-party domain), and that JavaScript runs, applying the experiments you’re running for any given situation. Since those experiments usually involve changing the display of the page in some way, these scripts are typically either loaded as blocking JavaScript (meaning nothing happens until the JavaScript arrives and gets execut

There are features many of us shy away from, like cursors, triggers, and dynamic SQL. There is no question they each have their use cases, but when we see a trigger with a cursor inside dynamic SQL, it can make us cringe (triple whammy).

In the past, software systems ran in highly controlled environments on-premise and managed by an army of sysadmins. Today, migration to the cloud is relentless; the stage has completely shifted. Systems are no longer monolithic and localized; they depend on many globalized uncoupled systems working in unison, often in the form of ethereal microservices.
