Hackers' Pub Introduces Flexible Username Changes: Breaking the Fediverse Norm
https://hackers.pub/@hongminhee/2025/hackers-pub-introduces-flexible-username-changes
Hackers' Pub · Hackers' Pub Introduces Flexible Username Changes: Breaking the Fediverse NormHackers' 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 choiceYour online identity can evolve as you doYour content history remains intact during the transitionYou 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.

Viele #X-User wechseln zu Bluesky - mit Vorteilen gegenüber dem ehemaligen #Twitter: „Offenheit, Transparenz, Partizipation und eine gleichmäßigere Machtverteilung“. Dazu gibt's mit dem #OpenSource-#Handle https://brid.gy eine 1a-Verbindung zu #Mastodon.

I made the #brass washer myself, on which I'll mate the tang.
Having fun with the handle. Something so soothing about the neat, tight, orderly stitches...

Lately I see a lot of posts from people who have deleted their #twitter / #X account.
My warning: beware of #impersonations
Once a handle disappears, someone can come along and impersonate you with all the digital trail we leave behind.
Tip: check in search engines periodically if your old #handle is being used.
Disclaimer: it happened to me with my #Facebook and #Gmail accounts. Someone tried to #scam my mother's friends by impersonating me.
Someone's handle on a social media platform is:
teadrinker
I read:
teardrinker
Give a very different vibe.

Better get a handle on that.
These have somehow gotten a standard size where you can rock up in the hardware store, wave your window handle around, buy the one model they have and it magically fits your window. Down to the length of the shaft and the size and length of the bolts. Amazing.
Easy job, for once.
#Schwiemu is breaking shit faster than I can fix it.
Part of this problem is that the PVC windows have been installed before the logs the house is made of were done shrinking, so now some of the windows are load bearing 
Die 9 Stufen der #iwp-Wertkette https://chaos.social/@plinubius/112758870170057894 taugen zur Kategorisierung von #Toots und #Handle. Handelt es sich um den Bericht zu einem Ereignis: Toot #kat2, Liste Berichterstatter. Meinungsäußerungen sind Beurteilungen, also Interpretationen und ergo Toot #kat7. Ob ein kat7-Toot interessant ist, hängt vom Umfang der in ihm dargestellten Informationen ab, also ob kat2-Information enthalten ist oder Verweise, d.h. welche Auswahl- und Dokumentationsleistung im Sinne von #kat5und6. 1/x

Ich schlage das Modell einer #Wertkette als #Analyserahmen vor, um Demokratie als einen informationswirtschaftlichen Wertschöpfungsprozess #iwp zu beschreiben, der Märkte für Informationsgüter und -dienstleistungen konstituiert. Nicht nur wird so ein analytisches und ideologiekritisches Nachdenken über Öffentlichkeit möglich, sondern auch die Konstruktion von Innovationen, die diese Märkte disruptiv verändern, und die Untersuchung deren Marktpotentiale und ihre absehbar transformativen Effekte.

@ctietze Mastodon nutzt #hashtags, die ich als Schlagworte verstehe und #handle, um den Autor zu referenzieren. Ein Toot ist i.d.R. eine 500-Zeichen-Notiz, in der man etwas für einen Neues formuliert und mit dem eigenen Vorwissen verknüpft. Das Microblog ist quasi der Zettelkasten, nur dass das Publikum eben nicht zwingend nur aus mir selbst besteht. Die strukturelle Ähnlichkeit von Mastodon mit dem Zettelkasten-Prinzip liegt auf der Hand. Warum sollte man es nutzen, wenn nicht genau deshalb?
Ich suche Texte zur Philosophie bzw. zu den Leitideen der #Mastodon-Entwicklung. Vor allem interessieren mich Gedanken zu #reblog später umbenannt in #boost, zum Sinn von #hashtags und Überlegungen zur Identität von Mastodon-Autoren und den damit verbundenen Funktionen wie #handle, Profil, Avatar, verifizierter Link usw. Ich las in diesem Zusammenhang auch bei Wikipedia zu Mastodon und kam hier auf die Verweise zur #wissenschaftskommunikation
