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!

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！

国漢文混用体からHolloまで

本発表では、韓国語の「国漢文混用体」（漢字ハングル混じり文）を自分のフェディバース投稿に実装したいという小さな目標から始まった旅路を共有します。 この目標を達成するために、ActivityPubのJSON-LDの複雑さやHTTP Signatures、WebFingerなどの仕様を理解する必要性に…

Some nice themes running through the Devroom at : storytelling from different national and international contexts (Italy, Netherlands, Germany, Europe); new apps and ideas (badgefed, splinter, FASPs, Spritely); building infrastructure and foundational tech (Bonfire, Fedify, Emissary). This is really great momentum! The speaker list today has been wonderful.

@andypiper@macaw.social just said at #FOSDEM that 2 years ago Mastodon had a booth. Last year Fediverse had half a day. This year, there's a FULL TRACK of #fediverse !

THAT is growth! That is EXCITEMENT! That is people spreading this thing. Keep up the amazing work ALL of you!

ALL OF US MAKE THIS WORK!

And I am so grateful to you for it.

Thanks all for listening to my talk about at 2026 today! Here's my deck for the talk: Fedify: Building ActivityPub servers without the pain.

Fedify: Building ActivityPub servers without the pain - Slidev

"Implementing ActivityPub looks simple at first—it's just JSON over HTTP,\nright? Then you hit JSON-LD context resolution. Then HTTP Signature\nverification fails on Mastodon but works on Misskey. Then you realize\nthe spec spans hundreds of pages across W3C documents and [FEPs] (Fediverse\nEnhancement Proposals), and every implementation interprets them differently.\n\nI went through this pain building [Hollo], a single-user microblogging server.\nHalfway through, I realized I was building a framework instead of an app.\nSo I extracted that framework and called it Fedify.\n\n[Fedify] is an opinionated ActivityPub framework for TypeScript. It handles\nthe protocol plumbing so you can focus on your application logic.\n\nIn this talk, I'll cover:\n\n - *Type-safe vocabulary:* The Activity Vocabulary spec is loosely defined,\n but Fedify maps it to strict TypeScript types. Your IDE knows that\n `Note.content` is a `LanguageString`, and calling\n `await create.getActor()` returns an `Actor` object.\n No more guessing at property shapes.\n\n - *Comprehensive signature support:* Fedify implements four authentication\n mechanisms—HTTP Signatures (draft-cavage), HTTP Message Signatures (RFC\n 9421), Linked Data Signatures, and Object Integrity Proofs (FEP-8b32).\n For HTTP Signatures, it uses [double-knocking]: trying RFC 9421 first,\n falling back to draft-cavage if rejected, and remembering the preference.\n This kind of interoperability work is exactly what you shouldn't have to\n do yourself.\n\n - *Framework-agnostic design:* Fedify works as middleware for Hono, Express,\n Fastify, Next.js, or any framework that speaks `Request`/`Response`.\n Bring your own database, ORM, and auth—Fedify only needs a key–value store\n for caching.\n\n - *CLI toolchain:* The `fedify inbox` command spins up an ephemeral server\n to receive and inspect activities. `fedify lookup` fetches any ActivityPub\n object by URL or fediverse handle—including from servers that require\n [authorized fetch]. No need to create throwaway accounts on production\n instances.\n\nI'll also share production stories: [Ghost chose Fedify] for federating their\npublishing platform rather than implementing the protocol themselves. Hollo\ndemonstrates single-user microblogging with full Mastodon API compatibility.\n[Hackers' Pub] shows how a developer community can integrate with\nthe fediverse.\n\nWhether you're building a new federated service or adding ActivityPub to\nan existing app, this talk will show you how Fedify turns months of protocol\nwrangling into days of actual development.\n\n[FEPs]: https://w3id.org/fep/\n[Hollo]: https://docs.hollo.social/\n[Fedify]: https://fedify.dev/\n[double-knocking]: https://swicg.github.io/activitypub-http-signature/#how-to-upgrade-supported-versions\n[authorized fetch]: https://swicg.github.io/activitypub-http-signature/#authorized-fetch\n[Ghost chose Fedify]: https://activitypub.ghost.org/day-4/\n[Hackers' Pub]: https://hackers.pub/\n"

@hongminhee hat mit Fedify ein Framework erstellt, also ein Software-Baustein, der anderer Software dabei helfen kann, schneller „fediversisch“ zu sprechen. Und das ist gar nicht so einfach. Um so wichtiger, dass es Fedify gibt. Die Blogsoftware Ghost nutzt es beispielsweise.

I’ll be talking about ties, the federated bookmark manager, today at FOSDEM - 14:00 in the Social Web devroom.

Come join and get some ties stickers!
