GWG Also, a double - in a property name, like h-u-whatever is that allowed? I know x is, but...
Seirdy, hepphepp[d], cygnoir[d] and prologic joined the channel
#
prologic IN order to prevent abuse of a websub's callback, you can verify you actually have a valid and confirmed subscription to the hubendpoint for self -- How how shall I respond to such bogus inbound notifs?
#
prologic 410 Gone by the looks of the RFC
#
prologic Is this right?

Zegnat GWG: I am not sure I understand the question. You can have as many - in an mf2 property as you want: “one or more '-' separated lowercase a-z words.”
#
jacky how does one compute 'feed frequency'?
#
jacky like I figure that you could find the delta between two 'published_at' values in a set of posts
#
jacky and from there, determine the average in change between those deltas
#
aaronpk I do it based on whether it changes between fetches
#
GWG Zegnat: I thought there was something on single letters
#
jacky aaronpk: that's clever
#
jacky sk
#
jacky agh vim-isms leaking out lol
#
jacky I'm thinking about adding this to my site but I can see this being helpful for a microsub server to inject into timeline info
#
sknebel inoreader shows "posts per week", not sure if thats last week or an average over X time

[snarfed] superfeedr's has a feed velocity measurement: https://documentation.superfeedr.com/schema.html#velocity
jacky joined the channel
#
jacky ahh thanks [snarfed]
#
jacky that's the bit I think I needed to understand maybe
#
jacky a unit to measure and then maybe see what to go from there
#
[snarfed] Bridgy also tracks and uses webmention and syndication link velocity (similar to feed velocity), eg https://brid.gy/about#missing

#
jacky regarding Vouch, I wonder if it's useful for people to consider something like https://en.wikipedia.org/wiki/Trust_on_first_use
#
jacky like if I've sent a Webmention to someone before and then I've recieved one from them, using those links as 'vouches' of 'good faith' especially if one's own internal moderation hasn't flagged them as such
#
jacky as a low friction (but also low marker) for vouches (since we can send multiple, it couldn't hurt)
#
[snarfed] yes! trust on first use is a great technique
#
[snarfed] can also use it as pass/fail, not necessarily part of Vouch at all
#
jacky oh like pass/fail for validating the Webmention itself?
#
[snarfed] sure, as an alternative to Vouch instead of part of it
#
jacky ah okay
#
[snarfed] but both are doable
MarkJR84[d], chenghiz_ and tetov-irc joined the channel; prologic left the channel
#
[snarfed] hah, jacky: https://web.resource.org/rss/1.0/modules/syndication/#description : "Description: Provides syndication hints to aggregators and others picking up this RDF Site Summary (RSS) feed regarding how often it is updated."
#
[snarfed] looks like WordPress RSS feeds include its sy:updatePeriod and sy:updateFrequency elements, eg https://snarfed.org/feed
