What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

"Ein »führender Verfassungsschützer« beschwert sich dort sogar, ein Verbot käme nun zur »Unzeit«, weil man gerade dabei sei, »in die Führungsebene einer Landes-AfD hineinzukommen«. Ein Satz, der aufhorchen lässt, schließlich war aus dem Debakel beim NPD-Verbot der Schluss gezogen worden, dass V-Leute keine steuernden Aufgaben übernehmen sollen."

Q: Why is so much Black music about violence and misogyny? I'm not racist, but is Black culture just more violent?

A: Racism. Rap, trap, and drill, are only the most popular genres of Black music listened to *by white people.*

@appassionatoearthling interesting detail here is that this is all intentional: the area is a floodplain that gets flooded naturally in periods of heavy rain or melting snow. When the rail line was constructed, the rails were built on top of a dam. Apparently that was in 1880!

(Maybe you already know all this, but I was curious so I did a quick search for an explanation.)

Ein knappes Jahr seit dem Wechsel ins Fediverse. Was mir fehlt: Austausch mit Künstlern und Kollegen aus Literatur und Show. Wo finde ich die? Gibt es Gruppen? Oder nur Listen? Wenn ich oder eingebe, finde ich nur eine Handvoll Einträge. Fühle mich ein bisschen verloren hier. Was ich nicht vermisse: Werbung, Filter und "Schaut-her-wie-geil-mein-Leben-ist"-Posts.

Hey Fediverse! 👋

We just wrapped up an amazing FediForum June 2025 a week ago, and BadgeFed was right in the thick of it! Here’s a recap of what we did, what we learned, and what’s next for decentralized badges.


BadgeFed at FediForum: Unconferences & Speed Demos

BadgeFed had the honor of presenting and hosting two unconference sessions and showing off our work in one speed demo slots (watch the demo). The energy was fantastic; lots of curiosity, sharp questions, and a real hunger for open standards in the credentialing space.

Community Feedback: Standards, Docs, and Openness

A big theme at FediForum was specs and open standards. We’re right there with you! That’s why we’ve enhanced our technical documentation to explain exactly how BadgeFed uses ActivityPub and OpenBadges together:

  • Issuers are ActivityPub actors, each instance can federate and follow others.
  • Badges are ActivityPub Notes with OpenBadge 2.1 attachments for maximum compatibility and verifiability.
  • Strict linking between issuer and badge, and between badge and recipient, to prevent spoofing.
  • Signature validation for both ActivityPub and OpenBadge data.
  • Federation: badges propagate via follows, and a special announcer actor helps with discoverability.
  • Comments and interactions: badges can be discussed and shared across the Fediverse.

Read more in our DETAILS.md.

Making BadgeFed Easier to Try

We heard you: people want to try BadgeFed! Right now, it’s a solo setup (one admin, one Docker container), but we’re working hard to make it easier for others to deploy, configure, and even federate their own instances. Stay tuned for updates on multi-admin support and streamlined onboarding.

Feedback: Discoverability vs. Spam

One of the most important pieces of feedback we received was about badge discoverability vs. timeline spam (see the issue). We want badges to be easy to find and share, but we also don’t want to flood the Fediverse with unwanted posts. This is now our top priority, we’re rethinking how verbose BadgeFed should be, and exploring opt-in/opt-out models for badge visibility and hashtag use.

What’s Next: Embedding & Profile Badges

We’re also working on ways to let you embed badges in your blog or add them to your Mastodon profile. More news on that soon!


FediForum was a fantastic experience, huge thanks to everyone who attended, gave feedback, and showed interest in decentralized credentials. Let’s keep building a more open, verifiable, and user-empowered Fediverse!

Badge up, and see you in the timeline! 🏅

And so comes over the next 24hs, the final issue of 's 25th year of issues and updates @blog.
)…

It's been an interesting experiment of using WordPress Plugin to publish a group blog - alongside an email newsletter. It's been more work than I expected. The only things that got more than a few likes and boosts were about Fediverse people.

More recently, changes to either the plugin or Mastodon's rendering has lost the paragraph breaks which makes it not as good for publishing/reading long-form as other APub tools (social.coop/@nicol/11609169297). The roadmap for the plugin (activitypub.blog/2026/02/11/ro) seems more about reading than growing to be a Fediverse publishing powerhouse, tho improving discoverability is promising - most of the authors suffer from the "no posts here!" problem when you visit the author urls.

Anyway, links should trickle out - finishing with an interview I'm really excited to share, having sat on it for five years…

The #ProxLB for #Proxmox Discord chat just moved to a new location!

As several people on Discord’s free plan are limited to join servers, I merged them all into a single one with different rooms. The new one is also for all ProxTools like #ProxLB, #ProxSnap, #ProxCLMC, #ProxWall and other projects!

You can simply join at: https://discord.gg/p9UxdMnx

PS: The #IRC and #Matrix bridge will be recreated asap!

I am becoming more and more frustrated with how Mastodon behaves towards the ecosystem.

After I finish with the current plans I have for GoActivityPub I have to push into making good enough to be used as a daily driver fediverse profile and switch to that.

I'm not entirely sure the inbox model of social consumption is good enough for others, but I think for me it'll have to be enough.

For obvious reasons, I'm naturally quite excited about the PL Squibs track, based on an idea we have shamelessly stolen from linguistics.

The idea of a squib is a short, to-the-point articulation of something that's important and worth having in the record, but may not fit the shape of a traditional full paper --- sometimes simply pointing something out clearly is all you need to drive the point home!

A squib might capture undiscussed limitations of a common approach, common assumptions that are now outdated, problems to solve that nobody has noticed yet, non-obvious lessons from some work, or other under-discussed matters of import to PL research. They are meant to be concise articulations for when these things can be treated fully in something quite a bit shorter than a typical research paper.

This is a class of paper that has existed for quite a while. My editorial about PL squibs (dl.acm.org/doi/10.1145/3785413) points out that TOPLAS has published papers that fit this heading in the past, and discusses why some of those papers fit the bill for PL squibs. But most of those papers are now 20+ years old, and it was never a class of papers that it was well-known were of interest to TOPLAS. Other times I've seen papers kicked around in traditional conference PCs with debates about whether something is really "a paper" or "a whole paper," and while most conference CfPs say papers aren't obligated to use the whole page limit... we all know that reviewers tasked with reviewing a dozen traditional papers will look askance at the odd one out. For PL squibs, brevity is a virtue, as long as it's telling the whole story.

I get that this is kind of a different category of papers, which the PL community isn't quite used to. So I fully expect to spend a lot of time answering email about whether or not X seems like it's in bounds for a PL squib submission. Don't be shy, my email address is public for a reason.
