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！

Fedify 2.3.0 is out! This release is largely about production observability: OpenTelemetry metrics now cover every major federation path, and a monitoring guide and runnable example stack ship alongside them. Also new: a delivery circuit breaker that holds queued activities for unreachable servers rather than retrying indefinitely; @fedify/backfill, a new package for reconstructing conversations via FEP-f228; and fedify bench, an ActivityPub-aware load testing command. Release notes: https://github.com/fedify-dev/fedify/discussions/821.

Thanks to @2chanhaeng (@fedify/uri-template), @z9mb1 (@fedify/backfill), @sabrinkmann (FEP-0837 vocabulary), @nyanrus (@fedify/lint/oxlint), and @fruitsssdev (--skip-install) for their contributions to this release.

@reiver The date has been confirmed for August 9th on our end as well!

Seonbi is a Korean typography tool. It fixes the small things I don't want to handle by hand: curly quotes, spacing around punctuation, hanja annotations, and other Korean prose conventions.

https://github.com/dahlia/seonbi

Gukhanmun converts mixed hanja-hangul Korean text into hangul-only output, using the Standard Korean Dictionary. It handles plain text, HTML, and Markdown, with parenthetical or ruby annotations when you need them. There's a CLI, a Rust crate, and a WebAssembly build.

https://gukhanmun.org/

Hongdown is the Markdown formatter I use across most of my own projects. Written in Rust, it enforces an opinionated style for headings, code blocks, lists, links, and East Asian wide characters. There are integrations for Neovim, VS Code, Zed, and Helix.

https://github.com/dahlia/hongdown

Upyo is a zero-dependency email sending library for TypeScript. It gives the same API for SMTP, Mailgun, Resend, SendGrid, Amazon SES, and more, so changing email providers doesn't mean rewriting your send code. Works on Node.js, Deno, Bun, and edge functions.

https://upyo.org/

Optique is a type-safe CLI parser for TypeScript. Instead of parsing arguments and then validating them separately, you describe the command shape in code and let TypeScript enforce it.

https://optique.dev/

LogTape is a zero-dependency logging library for TypeScript and JavaScript. It works in Node.js, Deno, Bun, browsers, and edge functions. I made it especially for library authors who want to emit logs without choosing everyone else's logger for them.

https://logtape.org/

Hackers' Pub is a federated social network for developers, built on ActivityPub. Think DEV Community or Zenn, but federated: people can follow you from Mastodon, Misskey, and other fediverse servers. Still invite-only and moving fast, but the code is AGPL-3.0.

https://hackers.pub/

Hollo is a single-user fediverse microblogging server, built on Fedify. It's for people who want their own Mastodon-style home without running a whole multi-user instance.

https://docs.hollo.social/

Fedify is a TypeScript/JavaScript library for building fediverse software with ActivityPub. It takes care of the annoying protocol parts: WebFinger, HTTP Signatures, inboxes, outboxes, and NodeInfo. Ghost uses it for their fediverse integration, and the work is backed by the @sovtechfund.

https://fedify.dev/

No day job. Just me, building F/OSS full-time on public grants and individual sponsorships. If my work has saved you time, please consider sponsoring me on GitHub: https://github.com/sponsors/dahlia.

I maintain Fedify, Hollo, Hackers' Pub, LogTape, Optique, Upyo, Hongdown, Gukhanmun, and Seonbi. A thread on each ↓

I know mise is basically a watered-down version of Nix, but practically speaking, it's just so much easier to adopt that I keep using it. Lately, I've been using mise in all the F/OSS projects I maintain.

@XavCC Thanks! Yeah, of course, I'm interested!

#LogTape 2.2.0 is out!

The headline is two new packages:

@logtape/lint adds lint rules for ESLint v8/v9 (flat config), Oxlint, and Deno Lint that catch common logging mistakes before they reach production: template literal interpolation in message arguments, eager property evaluation where lazy is needed, unawaited async log callbacks, and missing meta sink configuration.

@logtape/testing gives you createLogRecorder() and domain-aware assertion helpers, replacing the hand-rolled array-sink boilerplate that every project ends up writing.

Other highlights:

• context: true on Express/Hono/Koa/Elysia middleware handles request ID generation, x-request-id header propagation, and implicit context. One option instead of several moving parts.

• Seven performance optimizations on the enabled-logging hot path

• New logtape.org website

「マストドン」と言われていちいちキレるのは大人気ないかも知れないけど、小規模な「インスタンス」に細分化されていることからフルスタックのアプリケーション実装としての多様性が高めな点もFediverseの特徴としてあると思っていて、しかし「マストドン」と特定の実装で提喩されてしまうとその特徴が切り捨てられてしまうので……

@sabrinkmann Thanks! Stay tuned! 😎

@zundan 1年以上ずっと2.0アルファ版を使っていますが、問題がまったくなく満足しています。

@cheeaun Yeah, I personally prefer the compact syntax (which is widely used) over “readable” ones, but if people get hard to read them, “readable” ones can be a good alternative.

@cheeaun Yeah, exactly! I guess your ex-colleagues might be bothered if patterns were written in Parsec-style syntax. 🤔

The reason people avoid regular expressions is ultimately because of the syntax. No indentation, no comments. It might be a minority opinion, but I think the x (EXTENDED) flag should be the default for regex.

@stefan Thank you! 🥰
