洪 民憙 (Hong Minhee)

Hello! I'm Hong Minhee (洪 民憙), an open source software engineer in my late 30s, living in Seoul, Korea. I'm bisexual and non-binary (they/them), and an enthusiastic advocate of free/open source software and the fediverse.

I work full-time on @fedify, an ActivityPub server framework in TypeScript, funded by @sovtechfund. I'm also the creator of @hollo, a single-user ActivityPub microblog; @botkit, an ActivityPub bot framework; Hackers' Pub, a fediverse platform for software developers; and LogTape, a logging library for JavaScript and TypeScript.

I have a long interest in East Asian languages (CJK) and Unicode. I post mostly in English here, though occasionally in Japanese or in mixed-script Korean (國漢文混用體), a traditional writing style that interleaves Chinese characters with the native Korean alphabet. Wanting to write in that style was actually one of the reasons I joined the fediverse. Feel free to talk to me in English, Korean, Japanese, or even Literary Chinese!

#introduction

はじめまして！ソウル在住の30代後半のオープンソースソフトウェアエンジニア、洪 民憙（ホン・ミンヒ）と申します。バイセクシュアル（bisexual）・ノンバイナリー（non-binary）で、自由・オープンソースソフトウェア（F/OSS）とフェディバース（fediverse）の熱烈な支持者です。

STF（@sovtechfund）の支援を受け、TypeScript用ActivityPubサーバーフレームワーク「@fedify」の開発に専念しています。他にも、おひとり様向けのActivityPubマイクロブログ「@hollo」、ActivityPubボットフレームワーク「@botkit」、ソフトウェア開発者向けフェディバースプラットフォームHackers' Pub、JavaScript・TypeScript用ロギングライブラリLogTapeなどの制作者でもあります。

東アジア言語（いわゆるCJK）とUnicodeにも興味があります。このアカウントでは主に英語で投稿していますが、時々日本語や国漢文混用体（漢字ハングル混じり文）の韓国語でも書いています。実はこの文体で書きたくてフェディバースを始めた、という経緯もあります。日本語、英語、韓国語、漢文でも気軽に話しかけてください！

#自己紹介

安寧(안녕)하세요! 저는 서울에 살고 있는 30代(대) 後半(후반)의 오픈 소스 소프트웨어 엔지니어 洪民憙(홍민희)입니다. 兩性愛者(양성애자)(bisexual)이자 논바이너리(non-binary)이며, 自由(자유)·오픈 소스 소프트웨어(F/OSS)와 聯合宇宙(연합우주)(fediverse)의 熱烈(열렬)한 支持者(지지자)이기도 합니다.

STF(@sovtechfund)의 支援(지원)을 받아 TypeScript用(용) ActivityPub 서버 프레임워크 @fedify 開發(개발)에 專業(전업)으로 任(임)하고 있습니다. 그 外(외)에도 싱글 유저用(용) ActivityPub 마이크로블로그 @hollo, ActivityPub 봇 프레임워크 @botkit, 소프트웨어 開發者(개발자)를 위한 聯合宇宙(연합우주) 플랫폼 Hackers' Pub, JavaScript·TypeScript用(용) 로깅 라이브러리 LogTape 等(등)의 製作者(제작자)이기도 합니다.

東(동)아시아 言語(언어)(이른바 CJK)와 Unicode에도 關心(관심)이 많습니다. 이 計定(계정)에서는 主(주)로 英語(영어)로 포스팅하지만, 때때로 日本語(일본어)나 國漢文混用體(국한문 혼용체) 韓國語(한국어)로도 씁니다. 聯合宇宙(연합우주)에 오게 된 動機(동기) 中(중) 하나가 바로 國漢文混用體(국한문 혼용체)로 글을 쓰고 싶었기 때문이기도 하고요. 韓國語(한국어), 英語(영어), 日本語(일본어), 아니면 漢文(한문)으로도 말을 걸어주세요!

韓國語(한국어) 母語(모어) 話者(화자)로서 정말 하고 싶은 말이 많아지게 하는 글이네… 只今(지금) 東京(도쿄) 旅行中(여행중)이라 글을 쓸 수가 없는데, 있다가 角(각) 잡고 제대로 反駁(반박) 글을 써 봐야 할 듯.

(Disclosure: Using the name and logo of Encyclia – symbolically, since Encyclia is not a legal entity – I have an active monthly donation to @fedify on OpenCollective. However, I do not believe that this is getting me any preferential treatment, and in my observation the Fedify project treats all contributors and downstream implementers with equal respect.)

Seems as good a day as any to thank @hongminhee and team for the exemplary work on @fedify. Following Fedify's big 2.0 release, my two largest interoperability pain points in @encyclia can be fixed. 🙂

https://github.com/fedify-dev/fedify/issues/473 means that people using @gotosocial will finally be able to follow @encyclia accounts soon (whenever I finish the upgrade).

https://github.com/fedify-dev/fedify/issues/472 will let me (and others) handle more account resolution edge cases and reduce failure mode traffic after Fedify 2.1 is out.

this piece by @hongminhee is excellent. #copyleft

@monaco_koukoku ご報告ありがとうございます。まさに既知の問題で、先ほどGitHubのイシュー#472としてクローズされました。

問題の本質は、Delete(Actor)を送ってくるアクターはすでに削除済みであるため、署名検証に必要な公開鍵が取得できずFedifyが401 Unauthorizedを返してしまうことにあります。結果としてハンドラーが呼ばれないのは仕様どおりの動作ではあるのですが、Deleteの場合はそれが根本的に困るというわけです。

この問題は次のリリースのFedify 2.1.0で対処されます。InboxListenerSettersにonUnverifiedActivity()というフックが追加され、署名検証に失敗したアクティビティをアプリケーション側でオプトインして処理できるようになります。詳しい使い方はドキュメントをご参照ください。

現在お使いのv1.10.3では残念ながら組み込みの回避策がありません。v2.1.0の正式リリースはまだですが、プレリリースビルドv2.1.0-dev.513+f5543fcaがすでにnpmおよびJSRに上がっていますので、今すぐ試すことも可能です。

Legal vs. Legitimate, good article by @hongminhee

> Whatever courts eventually decide about AI reimplementation, the question we need to answer first is not a legal one. It is a social one. Do those who take from the commons owe something back? I think they do. That judgment does not require a verdict

"Can the commons expect something back from those who extract value?" is a key question of Social experience design. The answer forms one of 3 core principles: The Mindfulness principle.

No. You can't expect *anything* back. That philosophical insight is crucial to organizing a healthy commons that's able to retain its value and evolve.

Paint any principles and values on a flag but as long as the battle is scattered farmers holding feeble Copyright Law pitchforks against a vast drone army, its no use. Know thy enemy helps too. It's not proprietary code or corporations. It's hypercapitalism: The Rules of Battle.

I'm thinking of proposing a #fediverse/social web community track at @COSCUP 2026 (Aug 8–9, Taipei)—think FOSDEM's Social Web devroom, but in East Asia. Before I submit the CFP, I'd love to get a sense of what to call it. What do you think?

Title: Is legal the same as legitimate: AI reimplementation and the erosion of copyleft
Link: https://writings.hongminhee.org/2026/03/legal-vs-legitimate/

這篇文章討論了 chardet 這個 Python 編碼檢測庫在使用 AI 重寫後，授權和社會倫理問題的爭議。

### 文章翻譯與總結：

2026 年 3 月 9 日，chardet 庫的維護者 Dan Blanchard 發布了第 7.0 版本，此版本比之前快了 48 倍，並支持多核心，且重寫後完全新建，原始代碼相似度低於 1.3%。他聲稱藉由使用 AI（Anthropic 的 Claude）依照 API 和測試套件重寫，因而不受原 LGPL 授權約束，改採 MIT 授權。原作者 Mark Pilgrim 反對此作法，指出 LGPL 規定修改必須維持相同授權，且 AI 重寫並

@hongminhee@hollo.social said

The proposed solution is to split responsibility more aggressively: the C2S server should be nearly stateless and dumb, storing ActivityPub objects without interpreting them, while a separate “client” layer handles indexing, timelines, moderation, and exposes its own API to the frontend running on the user's device. It's a clean separation of concerns on paper.

This is exactly what I say in the talk that I still need to record, and why I was working on that ActivityPDS concept last september.

Salvatore Sanfilippo (@antirez) and Armin Ronacher (@mitsuhiko) both argue that #AI reimplementation of #copyleft libraries is fine. Their legal reasoning might be correct. That's not the point.

Legal and legitimate are different things—and both pieces quietly assume otherwise.

@vappster BotKit currently supports only a single bot per instance, but in the future releases, such limitation could be gone. See also this related issue: https://github.com/fedify-dev/botkit/issues/16.

Hey #ActivityPub friends. Are there any new ActivityPub / Mastodon features I should add to #ActivityBot?

It's a small bot-only ActivityPub server in a single PHP file.

https://gitlab.com/edent/activity-bot/

It can be followed, post images, allow quote posts, etc.

Is there anything else you would like a bot-server to be able to do?
