I've been thinking about client-server interactions in the #fediverse. #ActivityPub #C2S isn't widely used, and most clients rely on Mastodon-compatible APIs instead.
What if we created a new standardized API based on GraphQL + Relay for client-server communication, while keeping ActivityPub for server-to-server federation?
The Mastodon-compatible API lacks formal schema definitions for code generation and type checking, which hurts developer productivity. And ActivityPub C2S is honestly too cumbersome to use directly from client apps.
#GraphQL would give us type safety, efficient data fetching (only get what you need), and the ability to evolve the API without breaking clients. #Relay's features for pagination, caching, and optimistic updates seem perfect for social apps.
Would this be valuable to our community? What challenges do you see? How might we handle backward compatibility? And should this be formalized as an FEP?
Curious what others think about this approach.

As #Fedify's author, I'm contemplating its adoption beyond Ghost's #ActivityPub implementation. Finding potential users for ActivityPub tools seems challenging—perhaps I'm addressing a very niche need?
While the technical complexity of ActivityPub makes tools like Fedify valuable, I wonder about the actual market demand for federation outside specific communities.
Open, decentralized systems make sense to many developers, but businesses often prefer closed ecosystems that align with traditional models.
Still, I see potential as the #fediverse grows and digital sovereignty concerns increase. Fedify aims to lower the technical barriers to federation.
I'm curious: Which projects would benefit most from Fedify today? What would make federation compelling enough for platforms to implement?
Would appreciate perspectives from both developers and platform owners.

@nprofile…kgua Do you have a working branch implementing RFC 9421 in Mastodon? I'm implementing it in Fedify, and would like to test against Mastodon's implementation of RFC 9421.

I'm exploring a new idea called FediOTP (codename): an authentication system that uses #ActivityPub DMs to deliver one-time passwords, allowing any #fediverse account to authenticate with web services. Unlike current solutions that rely on specific APIs (#Mastodon, #Misskey), this would work with any ActivityPub-compatible server, increasing interoperability across the fediverse. Would love to hear your thoughts on potential challenges or use cases for this approach.

突然、日本語のネイティブスピーカーは旧字体を自然に読めるのだろうかと気になった。韓国で漢字教育を受けた私としては、中国語や日本語を別途学ぶまでは「國=国」くらいは知っていたが、「礙=碍」などは全く知らなかったから。（韓国の漢字は基本的に旧字体または繁体字に近い康熙字典体が標準）

2025-04-23 10:02:32

My stance on #ActivityPub's adoption of JSON-LD: Since we've already decided to use JSON-LD, I hope we do it properly. However, if we hadn't used JSON-LD from the beginning, things would have been much less complicated.
#JSONLD #fedidev

2025-04-23 04:18:30

🤔
Protocols such as ActivityPub are widely used and useful, but unfortunately are not the best option when efficiency is important. Messages are in plain JSON format, which is wasteful, and extensions by various implementations complicate the implementation.
XQ's focus on replacing JSON with Protocol Buffers seems misguided. While serialization efficiency matters, ActivityPub's fundamental bottlenecks are in its multi-hop network architecture and request patterns. Optimizing message format without addressing these core architectural inefficiencies is like polishing doorknobs on a house with structural issues. True performance gains would require rethinking the communication model itself.

I've been reflecting lately on projects like @nprofile…j979, @nprofile…d3ay, and @nprofile…xex2. Sometimes I wonder if I'm solving problems that very few people actually need solved. How many developers truly want to build their own #ActivityPub server from scratch?
It feels a bit like inventing shoes that let people walk on their hands all day. Would there be a viable market? How many would actually buy them?
That's the sense I get with these projects. They do have users who find them tremendously valuable, but the total user base is inherently limited. The tools serve an important function for a small audience of specialized developers.
There are moments when my motivation wavers. When the user community consists of just a handful of enthusiastic supporters, it's sometimes difficult to maintain momentum and justify the ongoing investment of time and energy.
And yet, there's something meaningful about creating specialized tools that solve complex problems well, even if they're only used by a few. Perhaps that's enough.

Another annoying thing about the current custom emoji spec in the fediverse: the type is just called Emoji instead of CustomEmoji. Such a small detail, but it creates unnecessary ambiguity between Unicode emojis and custom ones. I ran into this while implementing BotKit and had type name collisions with Emoji—had to use awkward namespacing to work around it. These little inconsistencies make implementation more tedious than it needs to be.

2025-04-19 14:57:36

As someone who has developed several #ActivityPub software implementations (Fedify, Hollo, BotKit, and Hackers' Pub), I believe one of the most frustrating features to implement in the #fediverse is #custom_emoji.
The challenges are numerous:
First, there's no standardization. ActivityPub specifications don't define how custom emoji should work, leading to inconsistent implementations across different servers like Mastodon and Misskey.
Rendering is particularly problematic. Emojis must display properly across different contexts (in text, as reactions, in emoji pickers) while maintaining quality at various sizes. Animated emojis add another layer of complexity.
Perhaps most concerning is the poor #accessibility. Most implementations simply use the emoji code (like :party_blob:) as the alt text, which provides no meaningful information to screen reader users (in particular, non-English speakers) about what the emoji actually depicts or means.
What really dampens my motivation to implement this feature is knowing I'm investing significant effort into something that ultimately creates accessibility barriers. It's disheartening to work hard on a feature that excludes part of the community.

생각해 보니 정작 저도 어제 飮食(음식) 사진 올릴 때 프로틴이 들어있는데도 CW도 別(별) 태그도 달지 않았기 때문에 堂堂(당당)하게 말할 처지는 못 됩니다만… @nprofile…ru55 님이 쓰신 引用(인용)한 글에 同感(동감)합니다.
크게 세 가치 側面(측면)에서 이야기해보고 싶은데요.
애初(초)에 @nprofile…ld07 님이 付託(부탁)하신 건 肉食(육식) 寫眞(사진)에 CW를 걸어달라는 것까지도 아니고, 필터링할 수 있게끔 通用(통용)되는 해시태그가 있었으면 한다는 말씀이셨는데요… 이게 어쩌다 肉食(육식) 寫眞(사진)에 CW 달아야 한다는 「無理(무리)한」主張(주장)으로 歪曲(왜곡)되었는지 모르겠습니다. (事實(사실) 왜 그런지 알 것도 같지만요.)
비건이라는 運動(운동)에 同意(동의)를 하든 안 하든, 맞팔한 사이에 비건이 있다면 肉食(육식) 寫眞(사진)을 올릴 때 苦悶(고민)하는 程度(정도)의 配慮(배려)는 그냥 사람과 사람 사이에서 얼마든지 할 수 있는 일 아닐까 싶습니다.
「肉食(육식) 寫眞(사진)까지 CW 걸어야 하냐」라는 꽤나 恣意的(자의적)인 「常識(상식)」(제가 정말 안 좋아하는 單語(단어)인데요… 이를테면 어떤 사람들에겐 트랜스젠더나 同性愛(동성애)도 常識(상식) 밖의 일이기 때문이죠)에 依據(의거)한 이야기를 하시는 분들도 많이 보였는데요. 그렇게 치면 韓國(한국)의 어떤 커뮤니티들은 그들의 「常識(상식)」에 依據(의거)하여 反女性主義的(반여성주의적) 主張(주장)도 橫行(횡행)하고 多分(다분)히 極右的(극우적)인 主張(주장)들도 便(편)하게 올리고 한단 말이죠. 애當初(당초) 「몇 안 되는 사람들까지 配慮(배려)해야 하냐」라는 말 自體(자체)가 暴力的(폭력적)이라는 認知(인지)를 한다면 그렇게 말할 수 없지 않을까 합니다. 비록 비건이 아니더라도요. (이를테면, 저는 비건이 아닙니다. 어제도 肉食(육식)을 했고요.)

I just discovered why some of my followers from larger #Mastodon instances (like mastodon.social) would mysteriously unfollow me after a while!
A pull request was just merged in Mastodon that fixes a critical bug in their follower synchronization mechanism.
Turns out Mastodon implements the FEP-8fcf specification (Followers collection synchronization across servers), but it expected all followers to be in a single page collection. When followers were split across multiple pages, it would only see the first page and incorrectly remove all followers from subsequent pages!
This explains so much about the strange behavior I've been seeing with #Hollo and other #Fedify-based servers over the past few months. Some people would follow me from large instances, then mysteriously unfollow later without any action on their part.
Thankfully this fix has been marked for backporting, so it should appear in an upcoming patch release rather than waiting for the next major version. Great news for all of us building on #ActivityPub!
This is why I love open source—we can identify, understand, and fix these kinds of interoperability issues together. 😊

Most #ActivityPub implementations include Mention objects in the tag attribute when someone mentions another actor within the content of a Note or Article. Should actor objects like Person or Group also include Mention objects in their tag attribute when mentioning other actors within their bio (summary)? Are there any implementations that already work this way? (I've checked Mastodon and it seems they don't include these mentions.) What are your thoughts on this?
