You haven't made any technical points. You just waffled nonsense about scalability. I see you're bowing out of the argument because you have no case. Once you have interrupts on a platform, you have polling. If you're stuck with polling you can't recover interrupts. Which is why we have websockets decades late. The truth is there is not tension between interrupts and polling. Interrupts are plainly superior, since you can opt out of them trivially. But the platform should not opt out ahead of the developer. This turns out to be inadequate, so we get polling implemented inside interrupts and then a separate mechanism for interrupts. And the interrupt driven stuff has stupid reload buttons and so forth on the GUI. It's dumb engineering because increases complexity and leads to bad results for the user. You have no case. Polling is dumb. And if you think software engineers ever needed "good reasons" to add a bunch of pointless complexity to things, then you simply have no clue on the history of software development.
I had not downvoted you, but I thought about it - because you are making ranty, ad hominem attacks ("lazy thinking", "dumb excuses"), and you appear to be ignoring or handwaving away all the actual points anyone makes. I have no interest in engaging you in any discussion for these reasons, and I expect that other people feel the same way: hence, downvotes and lack of replies. Feel free to do what you wish with this information.
Web applications are a very small part of the web as a whole.
you can implement polling with interrupts
But why would you?
Are you aware that the OS is using an interrupt-driven system to poll the server?
Yes. So? In that case, interrupts are a great fit. In others, they aren't.
This is just dumb engineering.
Why?
And to say that it's good for "most things" is just lazy thinking.
It's not good: it's better for most things. There's nothing lazy about evaluating the options and choosing one.
"Most things" are that way precisely because of the crappy architecture. Rationalisations.
Sure, everyone who implemented this shit is dumb and lazy. It couldn't be that they have good reasons for doing what they did.
I see you criticized me for not providing technical points, yet now you refuse refute them. I don't see the point of this conversation anymore.
