(Tacking on because this is currently the highest comment.)
When I come to HN, I usually read all topics on the front page, then open interesting ones in tabs. After opening 10 tabs, I hear music, then I find the culprit, close the tab, do not look back.
Never play music without user permission.
Generally I dislike websites that randomly start playing sound (and follow the same tab-close behaviour), but this was not ill-advertised or unexpected.
HN: should I continue to tag those?
I haven't ever submitted anything with autoplaying audio, but I imagine I'd use [autoplay] or similar.
Solving it in the community can solve the problem of people unwittingly stumbling upon it from here, but it doesn't solve the bigger problem, which is that autoplay is rude. (Surely we've all had the experience of not being able to find the tab from the huge group we just opened that's playing the sound.) It's good if sites see that they get fewer visitors with autoplay than without.
I'm not sure there is a good solution to auto-playing. People are fine with it on well-known sites like YouTube, Vimeo, Soundcloud, etc. And most people, when they unwittingly click on a YouTube link, blame the person who made the link, not the site itself. Bizarrely, the target of ire shifts to the site if it's not popular enough.
(Genuine question, as you stated it as a matter of fact. Not trying to be obtuse or annoying.)
You are right about YouTube and I actually think they should handle visitors that come from outside YouTube differently than visitors from inside the site. In the first case auto-play is annoying in the second it is what is wanted.
The new user announcement seems to be on a 7th (always attractive for a short amount of time - mainly minor but not always - I've listened for a short amount of time). The deletes seem to be biased towards a minor chord.
I might have mixed that all up, but the chord seems to show some dependency.
Or it is just late a night.
I looked at the source but I'm hardly a JS/Web expert.
Seems to be from here:
https://meta.wikimedia.org/wiki/Special:RecentChanges
https://wikitech.wikimedia.org/wiki/RCStream
but only found a list of weird addresses: https://github.com/hatnote/listen-to-wikipedia/search?utf8=%...
Looking at their other repos and the addresses you linked to, looks like the project for publishing the changes is at https://github.com/hatnote/wikimon, which is in turn getting changes from an IRC feed at https://meta.wikimedia.org/wiki/Research:Data#IRC_Feeds
Is there some way to be cleaning up old circles after X new ones (or X minutes?)
It already does this, inspect the DOM. The ones that fade away are removed as children of the <svg>.
In addition, the WikiPedia is so powerful because the green dominates the purple..
EDIT: Turns out you need to open TCP port 9000
