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！

STF(@sovtechfund)의 支援(지원)을 받아 TypeScript用(용) ActivityPub 서버 프레임워크 @fedify 開發(개발)에 專業(전업)으로 任(임)하고 있습니다. 그 外(외)에도 싱글 유저用(용) ActivityPub 마이크로블로그 @hollo, ActivityPub 봇 프레임워크 @botkit, 소프트웨어 開發者(개발자)를 위한 聯合宇宙(연합우주) 플랫폼 Hackers' Pub, JavaScript·TypeScript用(용) 로깅 라이브러리 LogTape 等(등)의 製作者(제작자)이기도 합니다.

東(동)아시아 言語(언어)(이른바 CJK)와 Unicode에도 關心(관심)이 많습니다. 이 計定(계정)에서는 主(주)로 英語(영어)로 포스팅하지만, 때때로 日本語(일본어)나 國漢文混用體(국한문 혼용체) 韓國語(한국어)로도 씁니다. 聯合宇宙(연합우주)에 오게 된 動機(동기) 中(중) 하나가 바로 國漢文混用體(국한문 혼용체)로 글을 쓰고 싶었기 때문이기도 하고요. 韓國語(한국어), 英語(영어), 日本語(일본어), 아니면 漢文(한문)으로도 말을 걸어주세요!

This is how monopoly looks… Remember, not a single book author, artist, or FLOSS developer has ever been paid. They just used all of your data to train AI and are now making billions in profits while you struggle to buy eggs. This is why monopoly is so bad. #ai #microsoft #openai

@hollo 간단…하려나요? 저는 어렵지 않긴 했어요. Railway에서 돌고 있는 데이터베이스에서 pg_dump로 데이터 백업 받고, 미디어 저장용 오브젝트 스토리지는 그대로 썼고요.

@hollo 저도 Railway에서 굴리다가 결국 홈서버로 옮겼습니다.

Firefox GNOME 테마를 適用(적용)했고, 아주 마음에 든다!

中學生(중학생) 때 내가 컴퓨터를 잘 안다고 생각해서 先生(선생)님들이 나에게 學校(학교) 電算室(전산실)을 맡겼는데, 어릴 때 公私(공사)를 모르고 學校(학교) 서버를 私用(사용)했던 것이 생각난다. Windows 서버였어서 IIS에 PHP를 붙여서 썼었다.

I wish #Zed had profiles like Visual Studio Code. The interference between extensions is annoying. For example, Biome and Deno both try to do formatting.

@realgsong 그래도 한국 통신사 로밍 통하면 안 막히던 것 같았어요!

Started writing a new FEP:

FEP-0151: NodeInfo in Fediverse Software (2025 edition)

Mentioned some best practices. What else should be added there?

If you’re a developer writing a GTK app and you want it to be accessible, you might want to check out the following links:

Okay, I've just deployed a bleeding edge #Fedify, which implements both RFC 9421 and double-knocking, to Hackers' Pub. If you'd like to test your implementations against a real server, please give it a try! (If you want to create an account, let me know—I can invite you.)

#fedidev #ActivityPub

@adiz Oh, that also looks cool! The layout is just not for me though, haha.

@thisismissem Yeah, indeed I have few disagreed answers too.

This is definitely the correct answer.

(This is a joke, but funny to me because I'm working on the AP T&S Taskforce)

@nki The typical one is a combination of ANSI layout and dubeolsik layout. I normally use the default Korean input methods built in operating systems.

Lately, I've been really into buying keyboards. The one I'm currently eyeing is the NuPhy Gem80. Has anyone used this keyboard before? I'm curious about your experience with it.

Just for fun... try this #ActivityPub quiz to test your knowledge of the protocol.

I got 19/20 on the ActivityPub Quiz!

I've taken a lot of jazz improvisation courses over the years. One bit of advice given is that "rhythm is king." Basically, it means that above all else, if you're not making rhythm and playing in time, whatever else you do, no matter how "correct" it might be in other ways, it's still going to sound messed up in a bad way.

I wonder if there's some kind of similar concept for software development.

Today, after several months of work and testing, Lume 3 was finally released.

🔥 🔥 🔥

Dedicated to all galician cantareiras.

Thanks to all people involved in this huge release.

@dansup

☝️ This is really great. Daniel Supernault, the Pixelfed developer, has created a general Fediverse on-boarding tool (https://fedidb.com/welcome), and is looking for feedback. This thread (begins here: https://mastodon.social/@dansup/114482960842967063) has lots of constructive suggestions already.

Let's pull our Fedi hive mind together to help Daniel refined this much needed capability!

Great job Daniel!

토스의 어떤 機能(기능)들은 모바일 앱보다는 데스크톱 웹으로 쓰는 게 더 便(편)할 것 같은데, 토스는 데스크톱 웹 버전은 만들 생각이 없으려나?

If you're wondering why I'm doing tonnes of OAuth implementation work in @hollo, it's because it allows me to more quickly ship prototypes of things like:
- Client ID Metadata Documents
- Expiring Access Tokens & Refresh Tokens
- Public Clients

Both of those are planned for Mastodon, but I'm still waiting on funding & needing to make upstream dependency changes or write entirely new dependencies.

By implementing in Hollo, I can get these features in the hands of downstream client developers like @cheeaun to have them test out and prepare for supporting these features. (They're all discoverable via OAuth Authorizatiob Server Metadata)

Like does a Mastodon API-like server support these things? Check the OAuth Authorization Server Metadata for client_id_metadata_documents_supported (or something) and check if grant_types_supported has refresh_grant and scopes has offline_access, or something like that.

And then that tells you how to interact with that Mastodon API-like server, e.g., do you need to dynamically register a client (current) or can you use Client ID Metadata Documents (future)

Getting these things into Mastodon can take significantly longer because of complex dependencies and extensive test coverage and other interesting issues. And then longer into developers hands due to release cadence & ease of development deployments

In between working on FIRES yesterday, I also finished up a rather substantial contribution to @hollo that I'd been working on.

https://github.com/fedify-dev/hollo/pull/130

It's an OAuth thing, which to end users shouldn't really change anything, but internally it helps pave the way for supporting PKCE and Device Code Authorization Grant Flow, the first shipped in Mastodon 4.3, the second I want to land in a future version of Mastodon (it's a low priority on the oauth roadmap but just because of a dependency issue)

This also increases the test coverage of Hollo too, which is neat.

Admittedly we're able to take some shortcuts in Hollo, like only supporting Bearer tokens and not access_token query parameter, because the latter really shouldn't be used.

We do currently only support client_secret_post as a client authentication mechanism, not client_secret_basic and none, so those need to be added too, to be more compatible.

@cheeaun Now it's fixed! Thanks!

다양한 의견이란 것은 존중되어야 하지만 기초적인 사실관계 자체가 틀려먹은 기반에서 나온 의견은 좀 철저하게 부술 필요가 있다

중국인이 부당하게 보험금을 타먹으니 전부 내쫓으라는 주장을 다양한 의견이랍시고 들고 오는 것 자체를 막아야

@cheeaun I think notifications are broken on Hollo? It says “You're all caught up.”
