"Reflections on my first day (ever) at FOSDEM"

I suspect that the fact that I'm hanging around my hotel room, writing this and doing other admin-y bits, rather says it all...

Reflections on my first day (ever) at FOSDEM

Yesterday was my first day ever at FOSDEM, a large conference about Free and open source software, held in Brussels.

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 first—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 mechanisms—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 auth—Fedify only needs a key–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 handle—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"

> O’Reilly said that he reached out to Moltbook’s creator Matt Schlicht about the vulnerability and told him he could help patch the security. “He’s like, ‘I’m just going to give everything to AI. So send me whatever you have.’” O’Reilly sent Schlicht some instructions for the AI and reached out to the xAI team.

거기까지 공부하는 데 시간을 쓰고 싶지 않은 것도 계속 모르는 이유 중 하나일듯… 블랙 숄즈 머튼 이해하는 것만 해도 한 세월 걸렸는데 이렇게 공부해서 언제 2026년을 따라잡겠어

【国内現存唯一無二かも？】独自のインデックスを持った新しい検索エンジンを作りました！
プライバシーに配慮した、新しい選択肢。

Rumi Search は、国内でインデックスを構築し、試験的ではありますが検索エンジンサービスを提供しています。

我々のログは、何と検索したか、いつ検索したかなどのデータが自動反映される機能を有していません。我々が収入を得るための広告もありません。

Googleなどの検索エンジンサービスは、莫大な費用と時間をかけてインデックスを構築してきました。そのため、Rumi Searchはまだその領域に達していません。

しかしながら、これは大きな挑戦です。

このシステムが行く末を、ぜひ、最後まで見届けてください。

アクセスはこちらから
↓
https://zssu.me/web-search (高性能/推奨)
または
https://search.zssu.me (シンプル)

※国内現存唯一無二というのは、検索エンジンのコアとなるインデックスを現在国内サーバーで構築していることを指します。なお、個人の実験等、見落としていて実は唯一無二ではないという可能性もあります。

Another thing with server I had to figure out painfully.

I always got the error message that my video was not between 250K and 40960K big.
Spent a lot of time to increase limits in PHP, nginx or through artisan tinker. Tried a 100M video and it still complained it wasn't between 250K and 512000K.

Had to dive into developers console to realize, the error code was 422 because there was not video uploaded. Transcoding failed in browser.

Why? 1. Spotify owner investing in the military and the biz of genocide, 2. Spotify hardly pays anything to the artists (only to the famous ones), 3. Spotify uses AI generated music to avoid paying artists

Boicot a Spotify - Marxem juntes el 30 de Gener

Llancem una crida a artistes, discogràfiques i oients dels nostres territoris per marxar juntes d'Spotify el dia 30 de Gener. El CEO de Spotify, Daniel Ek, ha invertit prop de 700 milions d'euros a Helsing, una startup armamentística alemanya que fabrica tecnologia militar amb intel·ligència artificial. Per molt que la tasca sembli difícil, fem-ho juntes. No serem còmplices de la massacre i l'extermini.

Today is a great day, the campaign starts (at least in Spain ;-))

So we decided with our family to leave spotify, for the reasons exposed here: social.coop/@Wtebbens/11597219

It was easy as this:
1. Move all playlists to another service, we are trying Qobuz for now. FreeYourMusic.com is an easy app to do that for you
2. Upload a BoicotSpotify.org banner into my inactive account (optional)
3. Hit the cancel option in the spoti account page
