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!
安寧하세요! 저는 서울에 살고 있는 30代 後半의 오픈 소스 소프트웨어 엔지니어 洪民憙입니다. 兩性愛者(bisexual)이자 논바이너리(non-binary)이며, 自由·오픈 소스 소프트웨어(F/OSS)와 聯合宇宙(fediverse)의 熱烈한 支持者이기도 합니다.
STF(@sovtechfund)의 支援을 받아 TypeScript用 ActivityPub 서버 프레임워크 @fedify 開發에 專業으로 任하고 있습니다. 그 外에도 싱글 유저用 ActivityPub 마이크로블로그 @hollo, ActivityPub 봇 프레임워크 @botkit, 소프트웨어 開發者를 위한 聯合宇宙 플랫폼 Hackers' Pub, JavaScript·TypeScript用 로깅 라이브러리 LogTape 等의 製作者이기도 합니다.
東아시아 言語(이른바 CJK)와 Unicode에도 關心이 많습니다. 이 計定에서는 主로 英語로 포스팅하지만, 때때로 日本語나 國漢文混用體 韓國語로도 씁니다. 聯合宇宙에 오게 된 動機 中 하나가 바로 國漢文混用體로 글을 쓰고 싶었기 때문이기도 하고요. 韓國語, 英語, 日本語, 아니면 漢文으로도 말을 걸어주세요!
In Chinese, Japanese, Korean, and Mongolian vertically-set text it is normal for list counters to sit upright above the start of the list. This article describes how to use CSS for this, and what doesn't yet work.
@robin_maki 조금 테스트 해 봤는데, 일단 팔로 관계라든가 동작 면에서는 문제 없이 되는 건 맞고요. 핸들에서 유저명 부분이 바로 업데이트되진 않네요. 이것 저것 해 봤을 때는 해당 인스턴스에서 누군가가 그 계정을 팔로를 했다거나, 검색 창에서 해당 계정을 쳐봤다거나 하면 업데이트가 되고요.
@cheeaun Yeah, they can break too if someone else takes your old username. And, yeah, old permalinks redirect to new permalinks with 301 Moved Permanently!
At-mentions will be rendered as was, although links will work.
Hackers' Pub is a community-focused platform where programmers and technology enthusiasts share knowledge and experiences. As an ActivityPub-enabled social network, it allows users to connect with others across the broader fediverse ecosystem, bringing technical discussions and insights directly to followers' feeds.
In the fediverse landscape, your username is typically set in stone once chosen. Most ActivityPub-powered platforms like Mastodon, Pleroma, and others enforce this permanence as a fundamental design principle. However, Hackers' Pub is charting a different course with a more flexible approach to digital identity.
One-Time Username Change: Freedom with Responsibility
Unlike most fediverse platforms, Hackers' Pub now allows users to change their username (the part before the @ in your Fediverse handle) exactly once during the lifetime of their account. This policy acknowledges that people grow, interests evolve, and the username that seemed perfect when you joined might not represent who you are today.
This one-time change limit strikes a careful balance—offering flexibility while maintaining the stability and reliability that's essential for a federated network.
Username Recycling: New Opportunities
When you change your username on Hackers' Pub, your previous username becomes available for other users to claim. This recycling mechanism creates new opportunities for meaningful usernames to find their most fitting owners, rather than remaining permanently locked to accounts that no longer use them.
For newcomers to the platform, this means a wider selection of desirable usernames might become available over time—something virtually unheard of in the traditional fediverse ecosystem.
Link Preservation: Maintaining Digital History
Worried about broken links after changing your username? Hackers' Pub has implemented a thoughtful solution. All permalinks containing your original username will continue to function until someone else claims that username. This approach helps preserve the web of connections and conversations that make the fediverse valuable.
This temporary preservation period gives your connections time to adjust to your new identity while preventing immediate link rot across the federation.
The Technical Foundation: ActivityPub Actor URIs
What enables Hackers' Pub to offer username changes while other fediverse platforms can't? The answer lies in how actor identities are implemented at the protocol level.
Hackers' Pub uses UUID-based actor URIs that don't contain the username. For example, a user with handle @hongminhee has an underlying ActivityPub actor URI that looks like https://hackers.pub/ap/actors/019382d3-63d7-7cf7-86e8-91e2551c306c. Since the username isn't part of this permanent identifier, it can be changed without breaking federation connections.
This contrasts sharply with platforms like Mastodon, where a user @hongminhee has an actor URI of https://mastodon.social/users/hongminhee. With the username embedded directly in the URI, changing it would break all federation connections, which is why these platforms don't allow username changes.
This architectural choice gives Hackers' Pub the technical flexibility to implement username changes while maintaining account continuity across the fediverse.
GitHub-Inspired Approach
Those familiar with GitHub might recognize this model—Hackers' Pub has adapted GitHub's username change policy for the fediverse context. This approach brings the best of both worlds: the option for identity evolution from centralized platforms and the federation benefits of the fediverse.
What This Means for Users
For Hackers' Pub users, this policy offers a significant advantage over other fediverse instances:
You can correct an unfortunate username choice
Your online identity can evolve as you do
Your content history remains intact during the transition
You maintain your social connections despite the change
The Future of Fediverse Identity
Hackers' Pub's username policy represents an interesting experiment in the fediverse—testing whether more flexible identity management can coexist with the stability needed for federation. If successful, we might see other platforms adopt similar approaches, creating a more adaptable yet still interconnected social web.
For now, users should consider this policy a compelling reason to choose Hackers' Pub as their fediverse home, especially if username flexibility matters to their online experience.
Hackers' Pub is currently in invitation-only beta. If you're interested in trying out the platform and its unique username policy, please leave your email address in the comments below. We'll add you to the allowlist, enabling you to sign up directly on the website. Note that this doesn't involve sending invitation emails—your address will simply be approved for registration when you visit the signup page.

Just published a post about Hackers' Pub's unique username change policy! Unlike most #fediverse platforms, they allow a one-time username change while preserving your connections and content history. It's all possible thanks to some clever #ActivityPub implementation using UUID-based actor URIs instead of username-based ones. If you're interested in trying it out, the platform is currently in invitation-only beta—check the post for details on how to request access!

memory unsafety may cause a lot of software crashes, but it also helps a lot of people jailbreak their game consoles, so, it;s impossible to say if its bad or not,
@hongminhee@hollo.social 결론적으로 한국에는 가사적으로 Rage Against the Machine에 비할 만한 아티스트가 없다고 보시는군요. 네, 저도 그렇게 생각합니다. Rage Against the Machine은 그들의 음악 스타일과 가사에서 매우 독특한 위치를 차지하고 있으며, 한국 음악계에서 그들과 직접적으로 비교할 만한 아티스트를 찾기는 어렵습니다.
