Title.
A small drunk goblin in every server throws a dart at a handwritten piece of paper with every post ever
I think your prompt was wrong there mate. He said small not swol.
Looks more like an orc, maybe it’s the goblins boss
Thank you Post Goblin, I love the work you do.
Can I buy him a beer or something?
I hear he likes beans
I KNEW it!
This is my favorite theory so far.
Can confirm. Found the process on my server. I named him frank.
https://join-lemmy.org/docs/contributors/07-ranking-algo.html is everything you need
To summarize it for people that don’t feel like clicking the link, it essentially takes the log of the post score and then divides it by an exponential function of the time since the post was published.
And this picture helps too: shows the decay in ranking scores for posts of different popularity (score) over time.
After a day or so, the curve flattens out. This probably explains why we keep seeing posts that are months old in “hot” - if not enough new material is being posted, after the first few pages of “hot”, posts that are 5 days old and 5 months old are essentially the same due to the exponential decay function that was chosen.
That page gives this equation:
Rank = ScaleFactor * log(Max(1, 3 + Score)) / (Time + 2)^Gravity Score = Upvotes - Downvotes Time = time since submission (in hours) Gravity = Decay gravity, 1.8 is default
My guess is that the “gravity” parameter is the issue at the moment. Something is needed to make the decay less steep, so that really old posts aren’t making it up to the top of the feed.
There might be some way of tuning the gravity parameter dynamically based on how much content is being submitted, perhaps aiming for something like “the average age of the first 200 posts should be 10 days” (I made those numbers up, but the basic idea would be that the time decay should be steeper when lots of content is submitted and less steep when content is infrequent?)
don’t worry, its already fixed. should be in the next release.
On my personal instance I’m running a build with that and its properly giving nice recent posts ( including the OP)
I understand some of the words you said. Sounds like you are the person to fix it 😁.
I know some of those words.
Yeah? Well… I understood that reference.
Thank you.
And the relevant source code
It would be kind of cool to be able to define yourself the function that decides this for your account.
Whatever is being upvoted the most recently.
I too would like to know this and am too lazy to look at the source code. Maybe tomorrow.
“Maybe tomorrow” is about one fifth of the human condition
Only one fifth? Those are rookie numbers.
Have to leave 79% for “eh”
Perhaps, it’s purpose is to help make old cold posts warmer by bringing them to the top.
Is that like a shit flambe?
“Shit Flambe” is my cool new hacker name.
