"My husband complains about the cold," the man said. "Can you teach me a spell to keep him warm?"
"I can teach you to bind hair into a net to catch heat," the wizard said, "using arcane counting and a pair of fine wands."
After a while, the man said "Isn't this knitting?"
"This, too, is magic."

in reply to Peter Lord • • •It automatically adjusts depending on how often the source posts articles. Presumably the idea is to avoid sending frequent requests to small servers that rarely publish. This does mean that if an account only publishes once a month or so, it'll probably take a day or so before you see the article.
It used to be configurable on a per-feed basis, but looking now I think that setting went away. It can still be configured in the database I believe.
The way Friendica does RSS polling is pretty broken. You're supposed to make conditional requests so that the feed only needs to be built when it genuinely has something new, and you're supposed to respect the retry time. That way you can request much more frequently without overloading the server. But implementing that would require database schema changes.

in reply to Matthew Exon • • •Ah, I see, many thanks.
I just found adjustPollFrequency() in the source which adjusts the feed "rating" based on the number of recent posts.
The feed I was looking at has a rating of 8 (polling once a day) but other feeds I have lower ratings (more frequently polled). Thats consistent with what I see.
Thanks again.
