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.

@SnoopJ The real solution to the trolley problem is to understand that it's not a problem, in the sense that it's presented.

You are given two options, both of which suck. But *you* didn't set this situation up. This situation is *the system*, and you are being told you're responsible for the outcome. You are not. Since only your hand is close enough to the lever, you can make a difference, but the fact that the problem exists in the first place, and therefore any outcome, is the responsibility of The System, not you. The System tries to make you think it's about you, that it's your fault this is happening, that whoever dies, it's on you. It is not. Don't believe what The System is telling you. You may be forced to live within it, but its evil outcomes are not truly your responsibility. The right answer is that, whatever you choose to do with that lever, proceed to work to dismantle The System that put those people on the track and sent the trolley toward them in the first place.

Thanks all for listening to my talk about at 2026 today! Here's my deck for the talk: Fedify: Building ActivityPub servers without the pain.

Fedify: Building ActivityPub servers without the pain - Slidev

"Implementing ActivityPub looks simple at firstโ€”it's just JSON over HTTP,\nright? Then you hit JSON-LD context resolution. Then HTTP Signature\nverification fails on Mastodon but works on Misskey. Then you realize\nthe spec spans hundreds of pages across W3C documents and [FEPs] (Fediverse\nEnhancement Proposals), and every implementation interprets them differently.\n\nI went through this pain building [Hollo], a single-user microblogging server.\nHalfway through, I realized I was building a framework instead of an app.\nSo I extracted that framework and called it Fedify.\n\n[Fedify] is an opinionated ActivityPub framework for TypeScript. It handles\nthe protocol plumbing so you can focus on your application logic.\n\nIn this talk, I'll cover:\n\n - *Type-safe vocabulary:* The Activity Vocabulary spec is loosely defined,\n but Fedify maps it to strict TypeScript types. Your IDE knows that\n `Note.content` is a `LanguageString`, and calling\n `await create.getActor()` returns an `Actor` object.\n No more guessing at property shapes.\n\n - *Comprehensive signature support:* Fedify implements four authentication\n mechanismsโ€”HTTP Signatures (draft-cavage), HTTP Message Signatures (RFC\n 9421), Linked Data Signatures, and Object Integrity Proofs (FEP-8b32).\n For HTTP Signatures, it uses [double-knocking]: trying RFC 9421 first,\n falling back to draft-cavage if rejected, and remembering the preference.\n This kind of interoperability work is exactly what you shouldn't have to\n do yourself.\n\n - *Framework-agnostic design:* Fedify works as middleware for Hono, Express,\n Fastify, Next.js, or any framework that speaks `Request`/`Response`.\n Bring your own database, ORM, and authโ€”Fedify only needs a keyโ€“value store\n for caching.\n\n - *CLI toolchain:* The `fedify inbox` command spins up an ephemeral server\n to receive and inspect activities. `fedify lookup` fetches any ActivityPub\n object by URL or fediverse handleโ€”including from servers that require\n [authorized fetch]. No need to create throwaway accounts on production\n instances.\n\nI'll also share production stories: [Ghost chose Fedify] for federating their\npublishing platform rather than implementing the protocol themselves. Hollo\ndemonstrates single-user microblogging with full Mastodon API compatibility.\n[Hackers' Pub] shows how a developer community can integrate with\nthe fediverse.\n\nWhether you're building a new federated service or adding ActivityPub to\nan existing app, this talk will show you how Fedify turns months of protocol\nwrangling into days of actual development.\n\n[FEPs]: https://w3id.org/fep/\n[Hollo]: https://docs.hollo.social/\n[Fedify]: https://fedify.dev/\n[double-knocking]: https://swicg.github.io/activitypub-http-signature/#how-to-upgrade-supported-versions\n[authorized fetch]: https://swicg.github.io/activitypub-http-signature/#authorized-fetch\n[Ghost chose Fedify]: https://activitypub.ghost.org/day-4/\n[Hackers' Pub]: https://hackers.pub/\n"

if youโ€™re not masking you may end up with which is no joke.

In Feb 2022 I got COVID. In March I had to stop working because I couldnโ€™t even focus long enough to make coffee let alone work.

By 2023 I found workarounds that enabled me to be a functioning parent and husband again.

In 2025 I found medication that enabled me to work and think again, but part time.

That is 4 years ago and I am not yet over Long Covid.

Mask Up
Wash hands
Use a CO2 meter as proxy for polluted air - stay under < 700 and you are probably safe indoors
If youโ€™re sick stay away from events and people

Do you repost content from other social platforms to the fediverse? e.g. reddit, instagram, etc? Do you link or use a screenshot?

(I'm not as thoughtful as @evanEvan Prodromou so don't come at me about poll question design).

What the actual fuck. It's not April Fools Day, right? This is real?! Fuck you, SpaceX. Maybe this will help regulators realize how fucking shortsighted companies' plans in orbit are?

Surely the FCC won't rubber-stamp-approve this one??... ONE MILLION STARLINKS FUUUUCCCKKKKKK

In a late Friday FCC filing, the company mentions deploying a staggering 'one million satellites' in orbits ranging from 500 kilometers to 2,000km.

Some nice themes running through the Devroom at : storytelling from different national and international contexts (Italy, Netherlands, Germany, Europe); new apps and ideas (badgefed, splinter, FASPs, Spritely); building infrastructure and foundational tech (Bonfire, Fedify, Emissary). This is really great momentum! The speaker list today has been wonderful.

THAT is growth! That is EXCITEMENT! That is people spreading this thing. Keep up the amazing work ALL of you!
