Same here. Just got one of those right after opening this post.
Also, just noticed the upvotes count changing frequently, like from 9 to 800+, then 400+, 100+, 800+ again. lol
The upvote jumping is caused by issues with the websocket implementation. As far as I heard they are going to get rid of websockets completely in the next version and have static page rendering instead.
Yup -- that's been reported too. It's not a great look. I've been looking at the up/down vote functionality, and it is literally triggering an INSERT to the DB every single time you click either button.
Is that because of some kind of event sourcing, though? That's not an uncommon way of handling these things.
Yes, of course it makes sense to do it that way. The issue is you can literally click the up arrow repeatedly as fast as you can and create some database load.
Usually, at least from my experience, it is good practice to put some logic client-side to prevent a user from repeatedly clicking a button accidentally (or on purpose -- hey, why did I get a double post?!). Even a quarter second delay can help.
Yeah, that kind of abuse prevention really shouldn't be client side at all. It's one thing to prevent a user accidentally causing harm, but if a bad actor can deliberately do it then we've got bigger problems.
