洪 民憙 (Hong Minhee)

Hello, I'm an open source software engineer in my late 30s living in #Seoul, #Korea, and an avid advocate of #FLOSS and the #fediverse.

I'm the creator of @fedify, an #ActivityPub server framework in #TypeScript, @hollo, an ActivityPub-enabled microblogging software for single users, and @botkit, a simple ActivityPub bot framework.

I'm also very interested in East Asian languages (so-called #CJK) and #Unicode. Feel free to talk to me in #English, #Korean (#한국어), or #Japanese (#日本語), or even in Literary Chinese (#文言文, #漢文)!

#introduction

こんにちは、私はソウルに住んでいる30代後半のオープンソースソフトウェアエンジニアで、自由・オープンソースソフトウェアとフェディバースの熱烈な支持者です。名前は洪 民憙（ホン・ミンヒ）です。

私はTypeScript用のActivityPubサーバーフレームワークである「@fedify」と、ActivityPubをサポートする1人用マイクロブログである 「@hollo」と、ActivityPubのボットを作成する為のシンプルなフレームワークである「@botkit」の作者でもあります。

私は東アジア言語（いわゆるCJK）とUnicodeにも興味が多いです。日本語、英語、韓国語で話しかけてください。（または、漢文でも！）

#自己紹介

TIL: Node.js introduced import.meta.main since its v22.18.0 and v24.2.0.

@monaco_koukoku それもバグのようですね。まもなくバグ修正をリリースいたします！

I wish there was a high-level functional programming language that transpiles to Go.

@olivia Thanks!!

今まで外国語で発表を全部で3回したんだけど、3回ともなぜか日本の聴衆の前だったんだ。1回は10年くらい前に日本語が全然できなかった時に英語で、残りの2回は去年に日本語でやったよ。

By the way, this talk is my first English presentation in almost 10 years, and I'm so nervous. I think I need to practice a lot. 😰

경찰에서 연락 받았습니다. 실종 8시간만에 신병확보 했다고 합니다.

무슨 일이 있었는지는 알 수 없습니다만, 현재 안전 확보된 상태라고 합니다.

걱정해주신 분들 정말 감사드립니다.

@bart Great, I'm going there when I have a time!

ioriについて

ActivityPubを部分的にサポートするioriは、自分のためのナレッジ管理サービスとして開発した。

現代では様々なブログサービスやナレッジ共有サービスが存在するが、どれもいつか滅びてしまうリスクを抱えている。

それは仕方がないことだが、自分が得た知識や情報がある日突然アクセスできなくなるのは避けたい。

そこで、ioriでは自分で情報のフローをコントロールできることを重視し、ActivityPubを通じて自由な形式でナレッジが共有できるように設計した。

特定のサービスのレコメンド機能に依存せず、読者が自分の好きなサービスから情報を取得できることを目指している。

@monaco_koukoku 該当のバグはv1.9.3およびv1.10.1で修正されました！

I'll be presenting @fedify at @fosdem 2026! My talk Fedify: Building ActivityPub servers without the pain was accepted for the Social Web Devroom. See you in Brussels on January 31–February 1!

Incredible news: Skip is now free and open-source for everyone!

@monaco_koukoku ありがとうございます！確認してみますね！

@monaco_koukoku はい、そちらにご投稿いただければ大丈夫です。ありがとうございます！

Fedifyってテスト用に相手のAPサーバーのモック的なのが使えるのね。署名やネットワークのことを気にせずにActivityの送受信をテストできると。素晴らしい。

@monaco_koukoku オブジェクトディスパッチャーを設定したのに、ctx.getObject()がnullを返すんですか？どうやらバグっぽいですね。よければ、イシュートラッカーに課題を作成していただけますか？🙏🏻

After much faffing about, I have implemented the dynamic #OAuth2 client creation for #GoActivityPub services using the Client ID Metadata Document[1] that's been proposed as a replacement(?) for RFC7591 (Dynamic Client Registration Protocol).

The changes are in both the Authorization service and in the BOX #ActivityPub client to server helper.

브라우저 API가 모두 ‘웹’ API는 아님
------------------------------
- 웹 플랫폼은 *표준화된 API* 위에서 동일하게 동작한다는 인식이 널리 퍼져 있으나, 실제로는 *브라우저 벤더별 인프라* 에 의존하는 API가 다수 존재함
- Geolocation, Speech, Push, Payments, Passkeys 등은 표면적으로는 웹 표준이지만, 내부적으로는 *Google·Apple·Microsoft의 서비스* 를 호출
- 동일한…

So, I wrote a longer piece on this: https://writings.hongminhee.org/2026/01/ethics-of-small-actions/index.en.html.

이 主題(주제)와 關聯(관련)해서 조금 더 길게 글을 써 보았습니다.

오늘 발견한 거: 위키피디아에는 LLM이 작성한 걸로 의심되는 징후를 모아서 정리한 글이 있더라.. https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing

"AD8K, with Dolby Vision"

Armin Ronacher, who even very recently has previously has been very pro ai agent vibecoding to the point of criticizing critics, seems to have stepped back and asked the question: are AI coding agent users all experiencing mass delusion... including himself? https://lucumr.pocoo.org/2026/1/18/agent-psychosis/

Conversation on lobste.rs is also interesting https://lobste.rs/s/0pxvyd/agent_psychosis_are_we_going_insane

I'm uncomfortable with using language that evokes slavery in the context of AI/LLMs. Actually, not just for AI/LLMs, but for any subject at all.

AI/LLM에 對(대)해 奴隸制(노례제)를 聯想(연상)시키는 表現(표현)을 쓰는 것에 拒否感(거부감)이 있다. 아니, AI/LLM이 아니라 어떤 對象(대상)에 對(대)해서든.

These days, my friends with ADHD and I have started calling our condition AD4K, or even AD8K, because our symptoms feel so severe. 😂

Dojang is a dotfiles manager I built a few years back and then basically abandoned. I'd accumulated enough friction points that I wasn't really using it myself anymore. Finally got around to addressing those issues and just shipped a new version: https://github.com/dahlia/dojang/releases/tag/0.2.0.

If you're curious about Dojang, the docs are here: https://dojang.dev/.

I know I made this project, but I have no idea why people are starring the repository for this Markdown formatter that I created solely for myself. 😂
