”The primary focus of this article is asynchronous control in digital electronic systems.[1][2] In a synchronous system, operations (instructions, calculations, logic, etc.) are coordinated by one, or more, centralized clock signals. An asynchronous digital system, in contrast, has no global clock. Asynchronous systems do not depend on strict arrival times of signals or messages for reliable operation. Coordination is achieved via events such as: packet arrival, changes (transitions) of signals, handshake protocols, and other methods.”

- Someone 9y agoThe thing being discussed is https://en.wikipedia.org/wiki/Asynchronous_method_invocation https://en.wikipedia.org/wiki/Asynchronous_method_invocation: ”asynchronous method invocation (AMI), also known as asynchronous method calls or the asynchronous pattern is a design pattern in which the call site is not blocked while waiting for the called code to finish. Instead, the calling thread is notified when the reply arrives.”
- he0001 9y agoUh, no. It was about if the world is asynchronous or not. I don’t have much to say about OP, but the “world is asynchronous” usually comes up in these discussions. I think that’s really wierd and wanted more info about it since I haven’t yet seen a convincing explanation about that.
- inyourtenement 9y agoYou're just misunderstanding the claim. People mean something like "most things in the world operate in a non-blocking manner". It's not some deep claim about the universe.
- he0001 9y agoIn this case perhaps, but it usually becomes some sort of deep claim of how the universe work. And I do think asynchronous computer execution is not even close to how the world operates, so it’s not even a good metaphor.
