I have a question about how to perform an asynchronous task in a while-loop until some condition is met. This is more of a theoretical question but I can see how this could be an issue in some scenarios. I'll try demonstrate the problem at an example
So I've been going over Beej's networking guide. On an earlier question, I was told that to remove a lot of the freezing happening due to blocking I/O I needed to use select to check file descriptors and such before receiving so I only received when
I like to avoid resetting data registers that don't need to be reset. For example, when streaming data through pipeline stages, if each stage has a valid bit, there is no need to reset the data registers. (I believe this eases routing and timing on t
