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！

Tsuzuri(綴り)が実運用(外部からのフォローや外部への記事の配信など)ができるようになったので、これをベースに拡張すればお一人様向けのActivityPub実装を作れそうだなと考えている

Tsuzuriにタイムラインや通知、フォロー、公開範囲の対応などをすれば一通り使えるものにはなるのではないかと

通知やフォローなどはTsuzuriの既存機能を拡張すれば良いからそこまで実装コストはかからなさそう

ただタイムラインや公開範囲などは考えることも多いと思うので、そこの見通しが立たない限りは実装しないかもしれない

Mastodonの引用機能やMisskeyなどの絵文字リアクションまで考慮するとなるとより難しくなる

ただ、お一人様向けのActivityPub実装が増えること自体は良いことだと思うので、うまくやる方法を考えたい

@evan @swf That means a lot, thank you! I'd love to take you up on that—will send you a DM with some specifics shortly.

🚨 #GNOME 50 will be released on March 18!

😍 Star or/and boost this post if you're excited! With 5 more days to go we just asked our developers to drop their final GNOME 50 release of their projects.

A good piece on why XML deserves a second look as a format for DSLs: XML is a cheap DSL.

I've long thought there are problems where XML genuinely shines, and the richness of its tooling ecosystem is a big part of that. What's unfortunate is that the XML boom of the early 2000s left people with bad associations—not because XML is bad, but because it got dragged into problems it was never suited for. Reflexively avoiding XML today isn't really a rational response to that history. It's just the hangover.

@Edent Unfortunately, there's no travel bursary—@COSCUP is a free, volunteer-run event. That said, if you need a visa to enter Taiwan, COSCUP can provide an official invitation letter to support your application.

実際、韓国人にとっては日本語能力試験（JLPT）の1級（N1）はかなり取りやすい方なので、「日本語のチュートリアルみたいなもの」という表現はあながち間違いではないかもしれない。😂

去年12月受けたJLPTの認定書きたなんか日本語が喋れる韓国のオタクたちがみんなN1って日本語のチュートリアルみたいなものだと言ってて最初は自慢するのかなと思ったけど最近これは割と事実だったなと気付いた

@bootlegrydia That's a fair point… Taiwan is genuinely difficult to get to for many people from the PRC, and I don't see that changing anytime soon.

That said, we're also hoping to bring a similar Fediverse & Social Web track to FOSS for All Conference later this year—an open source conference held in Seoul. If Taipei doesn't work out, Seoul might be a friendlier option. Stay tuned!

Update: we've decided to go ahead and submit the CFP to @COSCUP 2026. The track will be called Fediverse & Social Web—think FOSDEM's Social Web devroom, but in Taipei. #COSCUP is free to attend, like FOSDEM.

If the track is accepted, would you be interested in coming to Taipei (Aug 8–9) to give a talk?

(Boosts appreciated!)

I find the tension concerning the use of AI tooling in the open source community interesting.

On the one hand, here we have a community who believe code should be openly shared and can be used for any purpose; that's encoded in the license.

The only difference of opinion is whether the license should enforce this openness.

But there's also a very strong reaction by many in the same community to training AI on open source code.

Emotion is a large part of both beliefs: wanting to use open source, or against training AI on it. Emotional reactions are legitimate. There must be an underlying belief system that evokes both.

I can see this as "rage against the system" except that many of the same people do not seem to react as angrily if open source code is used by that same system in other ways. Even free software purists accept this reuse, as long as the source remains open.

Perhaps it's that this use of open source source code was never expected: you'd either reuse its functionality OR learn from it as a human. Machine learning doesn't fit that.

元々ブログとしては、はてなブログを使っていたんだけど微妙にリッチテキストを書くのが面倒くさくなってきていた

そのため、もっと簡単に文を綴れるブログが欲しいなと思い、ブログを作ることにした
ついでに「ActivityPub対応にすれば毎回ブログの記事をシェアする必要もなくなるので便利だよな」と考え、ActivityPub対応のブログとして「Tsuzuri(綴り)」を作った

開発にあたっては使い慣れたRailsを使い、サポートにLLMとFedifyを使ってローカル環境でのMastodonとの疎通確認とかを行った
正直FedifyとLLMとの組み合わせて雑にセットアップを任せられるの便利だった

今後は何かしら思いついたことを雑に書きつつ、何かしらのイベントで話せればと思う

I've been meaning to finish my ActivityPub guide since I started the first draft back in June 2018.

Yeah, I got a bit busy with Pixelfed and my other projects, but I have been working on it periodically since then.

I really do think we have the advantage in many respects, and now we have fully featured AP SDKs like @fedify, now more than ever we need better dev resources and guides.

Can't wait to ship this!

#ActivityPub #ActivityPubSocial

everybody says ActivityPub is too hard.

so i'm building the thing that proves them wrong.

debug tools. validators. real docs.

built by someone who actually ships projects people use (@pixelfed (1M+ users) and @loops)

activitypub deserves better resources. i'm making them.

it only takes one person to spark a revolution ✨

coming soon. stay tuned.

@tatmius はい、韓国にも実印はあります。もっとも、正確に言うと実印という表現はほとんど使わず、印鑑という表現を使いますが。

@tatmius そうですね、歴史的な経緯によるものだと言えるでしょう。もちろん、漢字表記のない名前を持つこともできますので、その場合は括弧内の漢字表記には姓だけを漢字で書き、名前はハングルで表記されます。21世紀の韓国では、漢字の名前は…うーん、実印を作ったり、役所で書類を書くときくらい以外は、ほとんど使われない気がしますね。

@tatmius はい、政府のデータベースに電算化されて記録されます。住民登録証にも漢字表記が出ますし。

Getting your fediverse project funded isn't easy, and while I've been especially fortunate, I do feel bad for projects that are rejected from grant requests or have few patrons/donations.

We're all in this together, and I wish we were able to attract corporate sponsors like other initiatives.

I hope this doesn't discourage devs and they keep building, because I was rejected from my first 2 grant applications before I got my first NLnet grant.

@tatmius 現代韓国では名前はたいていハングルだけで表記されるので、ハングルで見ると日本の名前より多いとも少ないとも言いにくい感じなんですが、裏にある漢字表記を見るとかなりバリエーションが豊富なんですよね。たとえば「민희」（ミンヒ）という読みひとつとっても、「民憙」「旻熙」「珉嬉」など、かなりの組み合わせがあって。ハングルで読むと同じなのに、漢字にすると全然違う名前、みたいな感覚です。

사실 LLM에 대한 몇몇 반론은 좀... 다양인(다양성)배제적이라고 생각하는 바예요

그래서 "LLM이 인간을 대체할 수 없다"는 몇몇 주장은 좀 공허한 것 같음. 예를 들어 LLM은 지능적이지도, 창의적이지도 않다, GIGO다, 데이터의 거울일 뿐이다 등등.

"LLM은 데이터의 거울일 뿐이다"라는 문장 자체에는 동의하는데, 인간은 다른가?는 잘 몰겠숭 똑같은 것 같은데
