Oh I didn't realize the entire vidzy github project was nuked github.com/vidzy-social/vidzy

There's a couple of archive snapshots of it though web.archive.org/web/2024110418 so at least somewhat preserved

📝 Sharkey/Misskey 實例重裝後的聯邦宇宙同步問題解決指南

如果你曾經重新安裝過 Sharkey 或 Misskey 實例,可能會遇到一個棘手的問題:其他實例的使用者突然無法與你正常互動了!

🔴 常見症狀:
• 好友請求卡在待處理狀態,無法接受或拒絕
• 你的大頭貼和橫幅圖片在其他實例上顯示不出來
• 遠端使用者嘗試互動時會收到錯誤訊息

🔍 問題根源:
這是因為 ActivityPub 協議設計時,假設每個使用者的識別碼(Actor URI)是永久不變的。但當你重裝實例後,系統會生成全新的使用者 ID 和加密金鑰,導致其他實例快取的舊資料失效。簡單來說,其他伺服器還在用舊地址找你,當然找不到!

解決方案:
最有效的方法是請對方實例的管理員刪除你的舊使用者記錄,系統就會自動重新抓取你的新資料。雖然會失去追蹤關係和歷史互動記錄,但這是最乾淨的解法。如果想保留資料,也可以選擇手動更新公鑰,但操作較為複雜。

💡 預防建議:
重裝實例前記得備份資料庫和設定檔!未來 ActivityPub 社群也正在開發身份可攜性的標準,希望能從根本解決這個問題。

📝 Solving ActivityPub User Sync Issues After Sharkey/Misskey Reinstallation

If you've ever reinstalled your Sharkey or Misskey instance, you might have encountered a frustrating problem: users from other instances suddenly can't interact with you properly!

🔴 Common Symptoms:
• Follow requests get stuck in pending status, unable to accept or reject
• Your avatar and banner images don't display on other instances
• Remote users receive error messages when trying to interact with you

🔍 Root Cause:
This happens because the ActivityPub protocol assumes that each user's identifier (Actor URI) is permanent. When you reinstall your instance, the system generates a completely new user ID and cryptographic keys, causing the cached data on other instances to become invalid. Simply put, other servers are still looking for you at your old address!

Solutions:
The most effective approach is to ask the admin of the remote instance to delete your old user record, allowing the system to automatically fetch your new data. While this means losing follow relationships and interaction history, it's the cleanest solution. If you need to preserve data, you can manually update the public key, though this is more complex.

💡 Prevention Tips:
Always backup your database and configuration files before reinstalling! The ActivityPub community is also developing identity portability standards to fundamentally solve this issue in the future.

📝 Sharkey/Misskey 再インストール後の連合宇宙同期問題の解決ガイド

Sharkey や Misskey のインスタンスを再インストールしたことがある方は、厄介な問題に遭遇したかもしれません。他のインスタンスのユーザーが突然正常にやり取りできなくなるのです!

🔴 よくある症状:
• フォローリクエストが保留状態のまま、承認も拒否もできない
• あなたのアバターやバナー画像が他のインスタンスで表示されない
• リモートユーザーがやり取りしようとするとエラーメッセージが表示される

🔍 問題の根源:
これは ActivityPub プロトコルが各ユーザーの識別子(Actor URI)が永久不変であることを前提に設計されているためです。インスタンスを再インストールすると、システムは全く新しいユーザー ID と暗号鍵を生成し、他のインスタンスにキャッシュされた古いデータが無効になります。簡単に言えば、他のサーバーはまだ古いアドレスであなたを探しているのです!

解決方法:
最も効果的な方法は、リモートインスタンスの管理者にあなたの古いユーザーレコードを削除してもらうことです。そうすれば、システムが自動的に新しいデータを取得します。フォロー関係や過去のやり取り履歴は失われますが、これが最もクリーンな解決策です。データを保持したい場合は、公開鍵を手動で更新することもできますが、操作はより複雑になります。

💡 予防のヒント:
再インストール前には必ずデータベースと設定ファイルをバックアップしましょう!将来的には ActivityPub コミュニティがアイデンティティの可搬性に関する標準を開発しており、この問題を根本的に解決できることが期待されています。

I went to a great meet up last night that focused on #atproto and its differences with #activitypub I learned a lot and came away appreciating its approaches to content ownership, identity management, and moderation

I am periodically upset that ActivityPub does not mandate a closed json-ld context for all objects. The reason it can accept new context definitions is basically so that useless examples can fit on less documentation space. It sacrifices practical interoperability for the theoretical comfort of developers.

Just opened an issue for a major new task for #Fedify: building an #interoperability smoke test suite.

To ensure Fedify-built servers federate correctly with the wider #fediverse, we're planning to run automated E2E tests in #CI against live instances of Mastodon, Misskey, and more. This is crucial for a framework's reliability.

You can see the full plan and discussion here:

It seems to me that lots of opinions about how to improve the fediverse miss the basic fact of federation. ActivityPub is a protocol (standard?) that allows information to flow freely between vastly different applications and servers. That allows for distributed social media among other things. There is no particular reason why you have to take advantage of that feature. Truth.social, for example, does not.

I think that this becomes obscured because there are a variety of different reasons for wanting your social media use to be based on ActivityPub. Truth.social was, presumably, that it works and is easy and cheap enough to deploy. That is probably quite attractive for less awful people. If I want a social media experience dedicated entirely to discussion of cats, I can probably make it happen at a reasonable cost by using ActivityPub. You might want to use it because it allows interoperability between different applications, so you don't have to have Instagram, Facebook, twitter, substack, etc. You might want it because it is non-commercial. You might want it because it gives you power over moderation.

These are all good reasons, but they do not result in the same outcomes for how the fediverse is run. They couldn't. In fact, there cannot be a how the fediverse is run anymore than a how the internet is run. What that means is that there will not be a fediverse. There will be kolektiva.social, truth.social, mastodon.social, cats.social and so on. The level of interaction that happens between them will be determined by the vision of people running the server.

It doesn't surprise me that some of the smaller instances that exist to provide a heavily moderated social media experience block mastodon.social which wishes to be part of a large, interoperable social media ecosystem or kolektiva.social which wishes to be part of a large, DIY non-commercial (left wing) social media ecosystem. When mastodon.social allows ads, I suspect Kolektiva will block it because the tension between the visions will become apparent. What does surprise me is that some people both want to take advantage of a distributed social media ecosystem whilst expecting uniformity of use.

@pheonix I've used for many years as well as other projects. I prefer , overall appreciate the and posts here... It's / friendly and most recently having used , i've moved a discovery project off there to Mastodon and my linktree works here without users having to be logged in, unlike Bluesky.

🌀 Misskey 帳戶遷移實際會遷移哪些資料? / What data is actually migrated during Misskey account migration? / Misskey のアカウント移行ではどのデータが移行されますか?



🇹🇼 中文 / Chinese (Traditional)
最近在研究 Misskey 的「帳戶遷移」功能,想更清楚了解它實際會遷移哪些資料。

目前看起來它會轉移「追隨與被追隨」的關係,但我不確定是否也包含:
• 使用者頭像、橫幅與簡介
• 貼文、圖片與附件
• 使用者設定與偏好

另外,如果兩台伺服器之間的聯邦協議(ActivityPub)通訊正常,是否代表遷移時能自動同步所有可用資料?

我想確認 Misskey 的帳戶遷移到底是偏向「社交關係導向」(像 ActivityPub 的 Move 活動),還是能完整搬移內容與媒體的「資料轉移」。
如果有開發者或懂協議的朋友能說明一下,會很感謝
🙏



🇬🇧 English
I’m trying to understand how Misskey account migration actually works.

From what I’ve seen, it seems to transfer followers and following, but I’m not sure if it also includes:
• Profile info (avatar, header, bio)
• Posts, images, attachments
• User settings or preferences

If both instances communicate properly over ActivityPub, does migration automatically sync all available data?

I’d like to know if Misskey’s migration is more like a “social relationship redirection” (similar to ActivityPub’s Move), or a full “data transfer” including posts and media.
Any insights from developers or experienced admins would be appreciated
🙌



🇯🇵 日本語 / Japanese
最近、Misskey の アカウント移行 機能について調べています。
実際にどのデータが移行されるのか、もう少し詳しく知りたいです。

現時点では、フォロー/フォロワー関係は引き継がれるようですが、
次の項目も含まれるのでしょうか?
• プロフィール情報(アイコン、ヘッダー、自己紹介)
• 投稿・画像・添付ファイル
• ユーザー設定や環境設定

また、サーバー間の ActivityPub 通信が正常な場合、自動でデータ同期が行われるのでしょうか?

Misskey のアカウント移行は ActivityPub の Move のような「ソーシャル関係の移動」なのか、
それともユーザーコンテンツを含む「完全なデータ転送」に近いのか、
開発者や詳しい方の意見をお聞きしたいです
🙏
