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

安寧(안녕)하세요, 저는 서울에 살고 있는 30代(대) 後半(후반) 오픈 소스 소프트웨어 엔지니어이며, 自由(자유)·오픈 소스 소프트웨어와 聯合宇宙(연합우주)(fediverse)의 熱烈(열렬)한 支持者(지지자)입니다.

저는 TypeScript用(용) ActivityPub 서버 프레임워크인 @fedify 프로젝트와 싱글 유저用(용) ActivityPub 마이크로블로그인 @hollo 프로젝트와 ActivityPub 봇 프레임워크인 @botkit 프로젝트의 製作者(제작자)이기도 합니다.

저는 東(동)아시아 言語(언어)(이른바 #CJK)와 유니코드에도 關心(관심)이 많습니다. 聯合宇宙(연합우주)에서는 國漢文混用體(국한문 혼용체)를 쓰고 있어요! 제게 韓國語(한국어)나 英語(영어), 日本語(일본어)로 말을 걸어주세요. (아니면, 漢文(한문)으로도!)

I asked Nano Banana to draw an ad poster for a fictional McDonald's menu item called the “McBook,” and this is the image that was generated.

We've got some updates on TypeScript 7! The new native port

- can type-check any project
- supports --build and --incremental
- has rich editor features implemented
- is still 10x faster

and is ready for you to try today!

12月中旬、弟と一緒に、1ヶ月間の出張に行っている妻に会いに東京へ行くことにした。

불교기(일본어 仏旗)는 한국에서는 자주 보이지 않지만 불교 상징으로서 외국에서는 종종 보인다. 이 깃발을 채택한 세계불교도우의회(WFB: World Fellowship of Buddhists)에는 한국의 불교 종파들도 참여하고 있다.

I wish I could lube my 10-year-old HHKB Pro 2 and tune the stabilizers so it sounds as good as the keyboard in this video.

결국 #해커즈펍송년회 에 커스텀 키캡을 배포해야 할 것 같다...

BotKitは、ActivityPubボットを作るためのTypeScriptフレームワークです。既存のMastodon/Misskeyボットとの違いは、ボット自体が独立したサーバーとして動作すること。プラットフォームのアカウントは不要です。

文字数制限もなければ、APIレート制限に悩まされることもありません。

bot.onMention = async (session, message) => {
  await message.reply(text`こんにちは、${message.actor}さん！`);
};

フェデレーション、HTTP Signatures、配送キューといったActivityPub周りの処理はFedifyがすべて引き受けます。ボットのロジックを書くだけです。

DenoでもNode.jsでも動きます。

https://botkit.fedify.dev/

#BotKit #Fedify #ActivityPub #TypeScript #Deno #NodeJS

BotKit은 ActivityPub 봇을 만드는 #TypeScript 프레임워크입니다. 일반적인 Mastodon/Misskey 봇과 다른 점은, 봇 자체가 독립된 서버로 돌아간다는 겁니다. 플랫폼 계정이 필요 없습니다.

글자 수 제한도 없고, API 호출 제한에 시달릴 일도 없습니다.

bot.onMention = async (session, message) => {
  await message.reply(text`안녕하세요, ${message.actor}님!`);
};

연합(federation), HTTP Signatures, 메시지 전달 같은 #ActivityPub 관련 처리는 Fedify가 알아서 해줍니다. 봇 로직만 짜면 되는 거죠.

#Deno 및 #Node.js 둘 다 지원합니다.

https://botkit.fedify.dev/

#BotKit #Fedify

#BotKit is a #TypeScript framework for building #ActivityPub bots. The difference from typical Mastodon/Misskey bots? Your bot runs as its own independent server—no platform account needed.

This means no character limits, no rate limiting headaches, no API restrictions.

bot.onMention = async (session, message) => {
  await message.reply(text`Hi, ${message.actor}!`);
};

The ActivityPub stuff (federation, HTTP Signatures, delivery queues) is handled by #Fedify under the hood. You just write your bot logic.

Works with both #Deno and #Node.js.

내 트리를 꾸며줘!

ActivityPub client development is coming along!

AP platform developers be warned, I be opening issues in your repo soon.

#ActivityPub #c2s

@dansup Did you apply to the NLnet 2026 fund? My team and I also submitted our application yesterday.

한국에도 NLnet이나 STA처럼 자유·오픈 소스 소프트웨어 프로젝트에 투자하는 기관이 있으면 좋겠다.

Personally, I believe “fediverse” should be a common noun, not a proper one, and since I think it has in fact become one, I tend to write it in lowercase.

#Note
日：局所変数，大域変数，有効範囲
韓：지역 변수(地域變數), 전역 변수(全域變數), 변수 영역 (變數領域)
英：local variable, global variable, scope
台華：局部變數、總體變數（資訊學會譯法，不是中國影響的「全局變數」）、範疇（後來受中國影響用「作用域」）

@simonzerafa Thanks, just registered fedify.studio!

@simonzerafa Yes, like a supercharged ActivityPub.Academy?

A while back I mentioned the idea of “Fedify Studio”—a web-based toolkit for #ActivityPub debugging and development. I've been quietly working on shaping that idea into something more concrete.

Nothing to announce yet, but it's looking like this might become a team effort rather than a solo project, which would be nice. We'll see how it goes.

아무래도 來年(내년)에는 海外(해외) 컨퍼런스에 많이 參加(참가)하게 될 것 같다. 一旦(일단) 只今(지금) 생각나는 것만으로도 네 個(개)나 있음:

• FOSDEM 2026 (브뤼셀)
• FediCon 2026 (밴쿠버)
• COSCUP 2026 (臺北(타이베이))
• TSKaigi 2026 (東京(도쿄))

@julian @liaizon Would FediCon happen in Vancouver again next year? If so I'd love to participate there and hang out!

apmodel 0.4.5

バグ修正だけ、特に新しいものとかはない (そもそも次になる予定な0.5.0まで破壊的変更無し)
https://pypi.org/project/apmodel/0.4.5/

@thisismissem @liaizon That would be great if we could do such an event!

@liaizon That sounds great! I'd love to visit Berlin if my schedule allows. Still figuring out flights and dates, but I'll let you know once things are more concrete.

Update: I just submitted a talk proposal to the Social Web Devroom at @fosdem 2026—Fedify: Type-safe ActivityPub for TypeScript. Guess I'm flying to Brussels after all. 😅

RE: https://mastodon.social/@dansup/115497711169256588

Seems like bsky starts experimenting using mediabunny (https://mediabunny.dev/) to compress videos https://github.com/bluesky-social/social-app/commit/0a7209c623fbaf1e34e6143017c907f30a3c8bb4

Loops did the same too.

The bundle size is quite big, tho' I think will still be smaller than ffmpeg-wasm (https://github.com/ffmpegwasm/ffmpeg.wasm), used on https://tools.rotato.app/compress (I've been using this for videos I upload here instead of Handbrake app)

Small note: the previous figure I'd shared for community support accidentally omitted the €1730 from GitHub Sponsors because I don't see that in my normal Stripe dashboard

The NLNet amount also jumped up as I was able to submit another request for payment, which has since been approved.

I've also submitted grant applications for FediMod FIRES (to continue development) and for the ActivityPub Trust & Safety Taskforce, which if approved will unlock funds for myself and others on the taskforce, allowing us to spend more time on that work.

Hey #fediverse people, I've an ask: If you appreciate all that I do for the fediverse and open social web, and you'd like to see me continue to do that work, please support my work financially.

Right now I'm having to look for work outside of the Fediverse because I simply cannot make ends meet.

I need €60-70k per year to support myself, with costs everywhere feeling increased (so that number may even be too low)

Right now, year to date, I've received a total of €20,170 in financial support from the community, and €22,450 from NLNet grants. I've also only had minimal freelance work this year, as I've been busy on grant work & try to focus on the fediverse & open social web.

So my total income isn't yet enough to be regularly sustainable. I've had problems being able to make rent payments this year because cashflow on grants comes in large chunks usually months after the work has been done.

So if you want to see me keep doing what I'm doing, please support my work!
