@hongminhee@hollo.social

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!

Hackers' Pub Introduces Flexible Username Changes: Breaking the Fediverse Norm

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.

Just published a post about Hackers' Pub's unique username change policy! Unlike most platforms, they allow a one-time username change while preserving your connections and content history. It's all possible thanks to some clever 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!

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.

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.
