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！

Sneak peak.

Working on @fedify/debugger, an embedded ActivityPub debug dashboard for Fedify applications. It will be shipped with Fedify 2.0.

Good reads:

― the 2024 blog post
― the 2026 discussion in Lobsters.

Incidentally, I did stop using Discord. No regrets.

#Discord

Just promoted XenoAtom.Terminal.UI to 1.0! 🎉

I have added 2 new features from the preview: placeholder and brush gradients usable with text controls! 🎨

I'm going to see if I can add an extension to XenoAtom.CommandLine library to generate beautiful command line help and I will be hopefully done with this entire sidetrack of projects! ☺️

URI는 고유하지만 WebFinger 핸들이 동일한 계정들에 대해 각 구현체들이 어떻게 대응하는지가 궁금하다...

@pkgupdt 음, 그렇다기 보다는 ActivityPub 具顯(구현)이 어카운트의 캐시에 依存(의존)하면 안 된다고 보시면 될 것 같아요. 🤔

@pkgupdt 實(실)은 도메인 네임 再使用(재사용)이 可能(가능)하긴 합니다. 서비스 終了(종료)하기 前(전)에 모든 어카운트에 對(대)한 Delete 액티비티를 날리면 (이른바 self-destruct) 確實(확실)하게 可能(가능)하고, 그렇지 않더라도 時間(시간)이 좀 지나면 可能(가능)해야 합니다.

Go try it out and give feedback!

#Haskell

@deach I'm not particularly knowledgeable about them. I used to spend a lot of time on implementing localization stuff, but not much on vertical text unfortunately.

This reminded me of articles by @huijing which have a lot more details and background:

- https://chenhuijing.com/blog/vertical-typesetting-revisited/ (2017)

Early bird CFP for @COSCUP 2026 seems available now. Anyone interested?

And of course, I'm already taking the first steps.

Just created a Matrix room for Fedify contributors: #fedify-contributors:matrix.org. If you'd like to contribute to Fedify or wonder how Fedify internals are going on please join there!

Did you know there's a community space for #Fedify, #Hollo, #BotKit, and other Fedify ecosystem projects?

Whether you have questions, want to share what you're building, or just want to hang out with fellow fediverse developers—come join us!

Someone at #FOSDEM asked us to put some promotional materials on our website that they could print for an event. There is now a section for that on the Branding page with our first poster:

@dansup Isn't Matrix enough for you? 😅

I'm not just working on @loops, @fedidb, @webintents, @activityrank, and other initiatives.

I'm also quietly rebuilding @pixelfed, preparing it for a major release that solves every bug and issue you've ever had.

It's not easy, or quick. I have to redesign and rewrite every page, including the admin dashboard.

But trust me, it will be worth the wait.

If you run a Loops server, you know what I mean 😉

#Pixelfed

I wish more free/open source software developers got paid for their work.

Dear FOSS maintainers,

here’s a list of funding programs currently accepting proposals for maintenance work:

Codeberg: https://codeberg.org/mechko/awesome-maintainer-funding

GitHub: https://github.com/mechko/awesome-maintainer-funding

Thanks to everyone who helped crowdsource it! I’ll keep it updated, issues and PRs are very welcome :)

#opensource #funding #maintenance #foss

@kai Yes!

This weekend I was thinking about programming languages. Programming languages for agents. Will we see them? I believe people will (and should!) try to build some. https://lucumr.pocoo.org/2026/2/9/a-language-for-agents/

Alright, maybe I should start by making a list of what needs to get done:

• Fedify STF milestone 3: ActivityPub debug tools
• Fedify 2.0 release
• Hackers' Pub renewal
• Optique new version release

What else was there...?

I've taken on way too much lately, and I just don't have the time or energy to handle it all properly…

@jedi Yeah, there are times I want to call my own code “slop.” 😂 But I think it's going too far to call someone else's work that.

For extra context: I'm saying this because I saw someone call my code “AI slop.”

I think it's rude to just dismiss someone's work as “AI slop” simply because it uses some AI.

Hi, new followers! Seems like a good time for a re-introduction.

I'm Hong Minhee (洪 民憙), a software engineer based in Seoul. My pronouns are they/them.

I build tools for the fediverse. Fedify is an ActivityPub server framework in TypeScript, Hollo is a single-user microblogging server (what you're reading this on), and BotKit is a framework for making ActivityPub bots. I care a lot about making federation more accessible to developers, which, as my recent JSON-LD rant probably made clear, sometimes means wrestling with parts of the spec I have complicated feelings about.

I'm a free/open source software person through and through, and a socialist, which informs how I think about tech. Lately I've been thinking a lot about LLMs. My position is probably not what you'd expect from either camp: I think the problem isn't the technology itself but the enclosure of the commons. I wrote about this at length here if you're curious: Histomat of F/OSS: We should reclaim LLMs, not reject them.

Outside of software, I have a long-running interest in CJK languages and writing systems. I'm always happy to talk about Chinese characters, Korean orthography, or the weird corners of Unicode where these things intersect.

Nice to meet you all, and thanks for following.

It's 7 AM in Korea right now, and I still haven't been able to sleep. I guess I've completely failed to adjust to the time difference.

@liaizon Thanks, I'm checking it out!

The Internationalization Working Group @webi18n has published the first draft of a Group Note titled "Text-to-Speech Rendering of Electronic Documents Containing Ruby: User Requirements".
