Does the #Bluesky bridge thing use some kind of odd
content-typewhen requesting profile data? I'm seeing these errors in my logs when my server tries to retrieve posts (as part of my reply retrieval functions):[2025-12-09T00:59:33Z ERROR enigmatick::retriever] Failed to fetch object from remote. URL: https://bsky.brid.gy/convert/ap/at://did:plc:oofa3qqoiszsmajbigfqskqv/app.bsky.feed.post/3m7egmddbwk2h, Status: 502 Bad Gateway, Body: <!doctype html> <html lang=en> <title>502 Bad Gateway</title> <h1>Bad Gateway</h1> <p>Couldn't fetch https://enigmatick.social/user/jdt as ActivityStreams 2: Couldn't decode as JSON</p>If I'm reading that right, my
retrieveris failing because the bridge is trying to retrieve my profile and can't convert it to JSON. But I verified that my profile is provided as JSON for requests with theseAcceptheader types:application/jsonapplication/activity+jsonapplication/ld+jsonapplication/ld+json; profile="https://www.w3.org/ns/activitystreams
...so I can't figure out what it's complaining about. I'll need to watch my varnish logs to see if I can capture one of the requests live from that perspective.

@jdt this seems like it could use a @snarfed.org tag :)

liaizon@social.wake.st I pinged him, he says he can't respond yet because of the aforementioned connection negotiation issue! 🙂

Hey jdt@enigmatick.social, sorry for the trouble! We send
Accept: application/activity+json, application/ld+json; profile="https://www.w3.org/ns/activitystreams", text/html; charset=utf-8; q=0.5with our AP fetches, which seems to make enigmatick.social 303 redirect to the HTML profile page, eg/@jdthere.(Sorry for the complicated Accept header! We get URLs from various places, so if a URL isn't an AP id, we want to fall back to handling it as HTML and find its AP object via a rel-alternate link.)

@julian@activitypub.space My guess is that his JSON processor is choking on a non-standard tag I have in my profile (e.g.,
keysorephemeral.webfinger). I should clean up the latter since it's intended for client operations only.But it is valid JSON either way. The
ephemeralobject might cause a JSON-LD parser to choke since I don't declare it in the@context. -

@julian@activitypub.space I think I see the issue on @snarfed's post on your site (thanks @snarfed). I don't currently handle
application/activity+jsonrequests for the URL (i.e., https://enigmatick.social/@jdt). I only handle those on the ID (i.e., https://enigmatick.social/user/jdt).I don't see any harm in adding that to the URL, so I'll add a
301to redirectapplication/activity+jsonrequests for/@jdtto/user/jdt.It's odd, though - my logs seem to indicate that the bridge server is requesting
/user/jdtalready. -
@julian@activitypub.space I see the issue clearly now and can reproduce it (thanks @snarfed). It's just the complexity of the
Acceptheader - I'll dig into why mynginxconfiguration isn't handling that well. -

if let Some(accept) = headers.get(header::ACCEPT) { if let Ok(accept_str) = accept.to_str() { if accept_str.contains("text/html") { log::debug!("Redirecting to presentation page"); return Ok(AbstractResponse::Redirect(Redirect::to(&format!( "/@{username}" )))); } if accept_str.contains("application/activity+json") { log::debug!("Returning application/activity+json"); return Ok(AbstractResponse::ActivityJson(ActivityJson(actor))); } if accept_str.contains("application/ld+json") { log::debug!("Returning application/ld+json"); return Ok(AbstractResponse::LdJson(LdJson(actor))); } } }Just a priority issue with the existence of
text/html. I'll rearrange. -

Acceptheader per RFC specifications now (i.e., by explicit weight first and by order second). -
@julian@activitypub.space BTW, I love that your interface uses rich formatting for markdown code blocks - so many platforms just phone that bit in.
Enigmatick uses highlight.js too, so I tend to use that a lot.

jdt@enigmatick.social thanks! Yeah it was important to me to get that right. That little highlight library has been chugging along all this time lol.

@phnt can be enabled by an admin via ui?

@lqdev@lqdev.me indeed, now I no longer see raw markdown 😁
-
Since I use custom markdown blocks for media posts, the raw markdown blocks were being rendered in Mastodon. That's now fixed and working as expected. Here's what that a media post (note with attachment) looks like.
I'm feeling really good about my implementation. I'll keep testing other post types but I'm feeling confident about deprovisioning my instance and moving entirely to my website soon.

@lqdev@lqdev.me hey, welcome to the Fediverse!
Couple smol things...
When I try to resolve your post by URL, I get a Person back, whoops! Not sure why on NodeBB, I see raw markdown. Was going to inspect source.content, but see #1 :sweat:

I could use some help. I'm trying to make a list of all the websites that list ActivityPub 1) software 2) instances and whose content isn't too out of date. Here are some I know:
https://fedidb.com
https://fediverse.observer/stats
https://the-federation.info
https://delightful.coding.socialWhat else is there? Which is your go-to list?

I just wrapped up the MVP to [connect my website to the Fediverse by implementing a small subset of ActivityPub](/notes/website-now-natively-posts-to-the-fediverse-2026-01-22/). [Nostr](https://nostr.com/) is a protocol I've heard about but hadn't dipped my toes into, until today. I downloaded the [Amethyst client from F-Droid](https://amethyst.social/). The following are my off-the-cuff initial impressions of Nostr. ## The Good - Creating an account was easy. I just provided a username and was immediately taken to the feed. - The protocol seems simple. It's "just keys and events". In some ways, this simplifies account creation and enables building simple relays that are event / task-specific (search, outbox, DM). - Amethyst is preconfigured with a set of default relays so it solves the empty feed problem. You just create an account, pull up the global feed, and immediately start receiving posts. - Live video? Given Nostr stands for (Notes and Other Stuff Transmitted by Relays), live video is covered under other stuff. Still I was pleasantly surprised to see it. ## Not Ideal? - The global feed is chaos. It's like drinking from a fire hose. There's so many posts coming in all at once it's hard to keep track. - Tons of DeFi content. From what I've read, there's a large DeFi community presence on Nostr. Personally, I don't care for DeFi and Bitcoin content. Building a curated feed over time though should address this issue and reduce the amount of this content I see on my personal feed. Overall, I like what I'm seeing and curating my feed is relatively simple to do so I'm not constantly bombarded with posts from the global feed. 😔just like with ActivityPub and the Fediverse, I already know I'm going to end up running my own relay and start cross-posting content from my site to Nostr. It's just a matter of time. First I want to get my ActivityPub implementation in a more stable state where it manages itself and I can feel comfortable directing folks to subscribe to my Fediverse content through my website instead of the instance I'm currently running. Once that's done, I'll take the lessons and patterns from my ActivityPub implementation and build something similar for Nostr.

@3rdi@mastodon.social @stevejb@beige.party I don't think it is a social network, Dan just made a landing page showcasing (his) Canadian alternatives.
