  • Added these files to xlog repo on github https://github.com/emad-elsaid…
  • this repo deploys to xlog.emadelsaid.com
  • trying the follow @xlog@xlog.emadelsaid.com still didn’t show anything. I thought maybe it crawls /@xlog and can’t find anyting. my profile on toot.community has a link tag. maybe that’s it
1<link href='https://toot.community/users/emad__elsaid' rel='alternate' type='application/activity+json'>
  • Crawling the link curl -H"Accept: application/activity+json" https://toot.community/users/emad__elsaid returns this json. which is an activity streams person https://www.w3.org/TR/activity…

  • Added the file after cleanup to github repo https://github.com/emad-elsaid…
  • Still nothing
  • I checked the code and it hits host-meta only if there is a problem fetching webfinger so removing host-meta shouldn’t be a problem
  • used ngrok locally and wrote an extension that handle these two files instead of static files and it worked

  • clicking the item shows the profile
