How to do distributed locking (2016)

Or they care but don’t bother checking whether what they’re doing is correct.

For example, in my field, where microservices/actors/processes pass messages between each other over a network, I dare say >95% of implementations I see have edge cases where messages might be lost or processed out of order.

But there isn’t an alignment of incentives that fixes this problem. Ie the payment structures for executives and engineers aren’t aligned with the best outcome for customers and shareholders.

"Microservices" itself is often a symptom of this problem.

Everyone and their dog wants to introduce a network boundary in between function calls for no good reason just so they can subsequently have endless busywork writing HTTP (or gRPC if you're lucky) servers, clients & JSON (de?)serializers for said function calls and try to reimplement things like distributed transactions across said network boundary and dealing with the inevitable "spooky action at a distance" that this will yield.
