What algorithm is used to sort the posts on lemmy? This is the 10th entry on my home feed sorted as Hot. It’s a 2 years old post. Why it is “hot” now?

top 7 comments

sorted by: hot top controversial new old

a bug that was/will be fixed that mostly stoped posts from aging properly. it and some other nice things should be in the next release.

I believe there will need an additional commit to increase the frequency of the age update (as I understand it, it's only once a week because the update query was too slow before this PR was merged)

it does the hot update every 15 minutes now and it pretty much instantly nuked the ancient posts when I started running with it.

Oh, nice! Can't wait for the next Lemmy release the.

if you're impatient like me you could just grab the latest code from git; there's another change in there that dramatically reduces the database size: my one person instance went from having a database dump taking 1.3 Gb to 250Mb.

Lemmy’s algorithm is broken, it will take time to fix it. Just sort by new for now.
