A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Cool!
Cans has source? I've been hacking on a per-instance community scraper (that pulls a list of communities from the community directory page) for !lemmy411[email protected], in an attempt to have a regularly published community list, but I'm a bit bogged.
I have links to the source for my crawler (written in nodejs with redis task queuing) on https://lemmyverse.net (GitHub link top right) 🤗 It's a bit messy at the moment but has all the community crawling stuff.
Wow. Stickied THAT to [email protected] thanks!
I’m probably going to put the source up shortly but how I decided to find communities is by scraping my instances “federated with” list from https://toast.ooo/api/v3/site
Then going through the /.well-known/nodeinfo -> /nodeinfo/v2.0.json (or whatever url the well-known gives) to check the software to make sure it’s a Lemmy instance
Then using the Lemmy rest API to paginate through the open communities for that instance
